BACKGROUND
I. Field
The following description generically refers to wireless communications, and more particularly to the use of variable standby modes to facilitate the reduction of energy consumption by a communication device in a wireless communication system.
II. Background
Wireless communication systems are widely used to provide various types of communication; for example, voice and / or data can be provided through such wireless communication systems. A typical wireless communication system or network can provide multiple users with access to one or more shared resources (for example, bandwidth, transmission power, ...). For example, a system can use a variety of multiple access techniques such as Frequency Division Multiplexing (FDM), Time Division Multiplexing (TDM), Code Division Multiplexing (CDM), Long Evolution Systems
2/49
Deadline (LTE) of third generation partnership project (3GPP), orthogonal frequency division multiplexing (OFDM) and others.
Generally, multiple wireless access communication systems can simultaneously support communication to multiple mobile devices. Each mobile device can communicate with one or more base stations through direct and reverse link transmissions. The direct link (or downlink) refers to the communication link from base stations to mobile devices, and the reverse link (or uplink) refers to the communication link from mobile devices to base stations. This communication link can be established through a single input single output system, multiple input signal output or multiple input multiple output (MIMO).
For example, a MIMO system can employ multiple transmission antennas (N<sub>T</sub>) and multiple receiving antennas (N<sub>R</sub>) for data transmission. A MIMO channel formed by the N transmission antennas<sub>T</sub> and reception N<sub>R</sub> can be decomposed into N<sub>s</sub> independent channels, which are also referred to as space channels, where N<sub>s</sub> <min {N<sub>T</sub>, N<sub>R</sub>}. Each of the N<sub>s</sub> independent channels can correspond to one dimension. The MIMO system can provide improved performance (for example, higher transmission capacity and / or greater reliability) if the additional dimensions created by the multiple transmit and receive antennas are used.
A MIMO system can support a time division duplex (TDD) and frequency division duplex (FDD) system. In a TDD system, direct and reverse link transmissions can be in the same frequency region so that the principle of reciprocity allows the estimation of the direct link channel from the reverse link channel.
3/49
This can allow the access point to extract transmission beam gain in the direct link when multiple antennas are available at the access point.
Wireless communication systems often employ one or more base stations that provide a coverage area. A typical base station can transmit multiple data streams for broadcast, multicast and / or unicast services, where a data stream can be a data stream that may be of interest to independent reception to a mobile device. A mobile device in the coverage area of that base station can be employed to receive one, more than one, or all data streams carried by the composite stream. Similarly, a mobile device can transmit data to the base station or another mobile device.
Typically, mobile devices use power (for example, battery power) while connected as well as during periods of communication with a base station and / or other mobile devices via the base station. The amount of energy consumed by a mobile device may depend in part on the configuration of the mobile device and / or function (for example, operation) being performed by the mobile device. The reduction in the amount of energy used by a mobile device is desirable since such a reduction can result in extended battery life and decreased cost of using the mobile device and battery.
SUMMARY
The following provides a simplified summary of one or more modalities to provide a basic understanding of such modalities. This summary is not an extensive overview of all the modalities considered, and is not intended to even identify key or critical elements of
4/49 or outline the scope of all or any modalities. Its sole purpose is to present some concepts of one or more modalities in a simplified form as a prelude to the more detailed description that is presented later.
According to one or more modalities and corresponding disclosure thereof, several aspects are described in relation to the facilitation of a reduction in energy consumption in a communication device (for example, mobile device) by employing several standby modes in the communication device . A mobile device can use a standby controller that can facilitate selection and / or switching to a desired standby mode based in part on predefined standby criteria. Standby modes can include a standby mode, light standby mode, and / or deep standby mode, for example. The mobile device may employ an analyzer that can operate in combination with the standby controller to evaluate information relevant for determining standby mode transitions, such as explicit signals (for example, message from the base station instructing a change in standby mode) standby), implicit signals (for example, no data exchange between the mobile device and base station for a predetermined period of time), the current standby state, and / or available standby states to determine whether a condition is met based in part on predefined standby criteria such that a transition to a different standby mode must be performed. If such a condition is met, the standby controller can facilitate the transition from the current standby mode to a different standby mode to facilitate the reduction of power consumption by the device
5/49 mobile.
According to related aspects, a method that facilitates the selection of a standby mode associated with a mobile device is described here. The method may include flagging to facilitate selection of a standby mode. In addition, the method may comprise selecting a standby mode based in part on a predefined standby criterion.

The wireless communication equipment may include a signaling means to facilitate the selection of a standby mode. In addition, wireless communication equipment may include a means of selecting a standby mode based in part on a predefined standby criterion.

DETAILED DESCRIPTION
Several modalities are now described with reference to the drawings, where similar reference numerals are used to refer to similar elements from beginning to end. In the following description, for the sake of explanation, numerous specific details are set out to provide a complete understanding of one or more modalities. It may be evident, however, that such (such) modality (s) can be put into practice without these specific details. In other instances, well-known structures and devices are shown in the form of a block diagram to facilitate the description of one or more modalities.
As used in this order, the terms component, module, system, and the like may refer to a computer-related entity, whether hardware, firmware, a combination of hardware and software, software, or running software. For example, a component can be, but is not limited to, a process that runs on a processor, a processor, an object, an executable, a flow of execution, a program, and / or a computer. As an illustration, both an application that runs on a computing device and the computing device can be a component. One or more components can reside in a process and / or execution flow and a component can be located on a computer and / or distributed between two or more computers. In addition, these components can run from various computer-readable media having multiple data structures stored therein. The
10/49 components can communicate via local and / or remote processes as per a signal having one or more data packets (for example, data from one component interacting with another component on a local, distributed system , and / or through a network such as the internet with other systems using the signal).
In addition, several modalities are described here with respect to a mobile device. A mobile device can also be called a system, subscriber unit, subscriber station, mobile station, mobile, remote station, remote terminal, access terminal, user terminal, terminal, wireless communication device, user agent, device user, or user equipment (UE). A mobile device can be a cell phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop station (WLL), a personal digital assistant (PDA), a portable device having capacity wireless connection device, computing device, or other processing device connected to a wireless modem. In addition, several modalities are described here with respect to a base station. A base station can be used to communicate with mobile device (s) and can also be referred to as an access point, Node B, or some other terminology.
In addition, various aspects or features described here can be implemented as a method, equipment or industrial product using standard engineering and / or programming techniques. The term industrial product, as used herein, is intended to encompass a computer program accessible from any computer-readable device, carrier or medium. For example, computer-readable media may include, however,
11/49 is not limited to, magnetic storage devices (eg hard disk, floppy disk, magnetic strips, etc.), optical discs (eg compact disk (CD), digital versatile disk (DVD), etc.). ), smart cards, and flash memory devices (for example, EPROM, card, stick, key unit, etc.). In addition, various storage media described here may represent one or more devices and / or other machine-readable media for storing information. 0 Machine-readable means may include, but are not limited to, wireless channels and various other means capable of storing, containing and / or carrying instruction (s) and / or data.
Referring now to Figure 1, a wireless communication system 100 is illustrated according to the various modalities presented here. System 100 comprises a base station 102 that can include multiple antenna groups. For example, an antenna group can include antennas 104 and 106, another group can comprise antennas 108 and 110 and an additional group can include antennas 112 and 114. Two antennas are illustrated for each antenna group; however, a greater or lesser number of antennas can be used for each group. Base station 102 may include a transmitter chain and a chain which may, in turn, additionally receive a receiver, each comprising a plurality of components associated with transmitting and receiving signals (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be recognized by a person skilled in the art.
Base station 102 can communicate with one or more mobile devices such as mobile device 116 and mobile device 122; however, it must be recognized that base station 102 can communicate substantially with
12/49 any number of mobile devices similar to mobile devices 116 and 122. Mobile devices 116 and 122 can be, for example, cell phones, smart phones, laptops, portable communication devices, portable computing devices, satellite radios, global positioning systems, PDAs, and / or any other appropriate device for communicating via wireless communication system 100. As shown, mobile device 116 is in communication with antennas 112 and 114, where antennas 112 and 114 transmit information to mobile device 116 via a direct link 118 and receive information from mobile device 116 via a reverse link 120. In addition, mobile device 122 is in communication with antennas 104 and 106, where antennas 104 and 106 transmit information to mobile device 122 via a direct link 124 and receive information from mobile device 122 via a reverse link 126 . In a frequency division duplex (FDD) system, direct link 118 may use a different frequency band than that used by reverse link 120, and direct link 124 may employ a different frequency band than that employed by the link reverse 126, for example. In addition, in a time division duplex (TDD) system, forward link 118 and reverse link 120 may use a common frequency band and forward link 124 and reverse link 120 may use a common frequency.
Each group of antennas and / or the area in which they are designated to communicate can be referred to as a sector of base station 102. For example, antenna groups can be designed to communicate with mobile devices (for example, 116) over a sector of the areas covered by base station 102. In communication through links
13/49 direct 118 and 124, the transmission antennas of the base station 102 can use beam formation to improve the signal / noise ratio of direct links 118 and 124 for mobile devices 116 and 122. In addition, while base station 102 uses beamforming to transmit to mobile devices 116 and 122 randomly dispersed through an associated cover, mobile devices in neighboring cells may be subject to less interference compared to a base station that transmits over a single antenna for all your mobile devices.
According to one aspect, a mobile device (eg 116) can be configured in such a way that such a mobile device can transition (eg switch) between different modes, such as deep standby mode (DS), standby mode (LS) and / or continuous reception mode (CRX) based in part on predefined standby criteria. In one aspect, the mobile device (for example, 116) can have cycles (for example, batch transmission (DTX)) where each cycle can include a linked period where the mobile device can monitor transmissions from base station 102 and / or an off period where the generation of radio frequency (RF) can be turned off on the mobile device to facilitate the reduction of energy consumption. 0 The length of a specific cycle associated with a specific mode can be based in part on the total length of a respective off period combined with a respective on period in the cycle. Thus, for example, since the off period associated with DS mode can be longer than the off period associated with LS mode, the DRX cycle for DS mode can be longer in length than the DRX cycle for DS. LS mode. In one aspect, DS mode can have a cycle (for example, DRX cycle) with an off period
14/49 specified associated with discontinuous reception (DRX) which can be longer than the specified off period for a cycle associated with LS mode or the specified off period for a cycle associated with CRX mode (for example, which may have its period off set to 0) to facilitate the reduction of energy consumption (for example, reduce the use of battery energy). During the disconnected period, the mobile device (for example, 116) can disconnect (for example, disable) its RF generation (for example, where there is also a batch transmission period (DTX)) where during the disconnected period the mobile device does not is able to receive data or control information, to facilitate the reduction of energy consumption. 0 DS mode can also have a specified off period associated with DTX which can be longer than the off period associated with LS mode or CRX mode (for example, which can have its off period set to 0) to facilitate reduced consumption power. DS mode can also have a linked period of time specified during a cycle, where the linked period may occur less frequently than a linked period for LS mode, and where the mobile device (eg 116) can receive certain information (e.g., control information) during such linked periods. DS mode can also have a connected time period specified during a DTX cycle. While in DS mode, the mobile device (eg 116) is not able to transmit data over the data channel, but it can receive and / or transmit control information through the control channel during the connected period (eg, intervals connected). To exchange data with base station 102, the mobile device (eg 116) must transition out of DS mode to
15/49 LS mode or CRX mode.
The LS mode can have a different cycle than the DS mode, since the off period associated with DRX, in comparison with the DS mode, can be a shorter length of time than the off period associated with DRX of DS mode. LS mode can also have a defined off period associated with DTX which can be shorter than the off period associated with DTX of DS mode. 0 LS mode can still have a defined on-time period related to DRX, which can occur more frequently than periods connected to DS mode (but can occur less frequently than CRX mode, which can be turned on continuously to receive information) , where data and / or control information can be received during such non-DRX partitions. LS mode can have a defined on-time period associated with DTX. While in LS mode, the mobile device (for example, 116) can transmit and / or receive data through the data channel and / or control information through the control channel. In LS mode, the mobile device (eg 116) can facilitate the reduction of energy consumption, although the reduction in energy consumption is not typically as large as the reduction in energy consumption while in DS mode.
In CRX mode, the mobile device (for example, 116) can be in a state where it is turned on (for example, in non-DRX mode) at all times while in such a mode, and is capable of receiving data and / or information from control. That is, in CRX mode, the off period can be set to 0 so that there is no off period during a cycle. According to one modality, the CRX mode (for example, non-standby mode) can be considered a special mode associated with the LS mode, where for the CRX mode, the
16/49 off period can be set to 0, where the cycle can be made up of a series of linked partitions, for example, so that the mobile device (for example, 116) can be in a continuously on state. In this way, the LS mode can be configured so that the off period is set to 0, and the mobile device (for example, 116) can be in a continuously on state. While in CRX mode, the mobile device (for example, 116) can typically consume more power than when the mobile device is in LS mode or DS mode.
The length of an off period (for example, respectively associated with DRX and DTX) can be configurable, as desired, and can range from 0, which can be associated with CRX mode, for example, to a desired number of seconds (for example , 2 seconds), where the length of the off period can typically be longer for DS mode than LS mode. The length of a linked period (for example, associated with DRX and DTX respectively) can be configurable, as desired, and can vary from 1 ms to more than 1 ms. The respective lengths of an off period and / or an on period can be based in part on the type of mode (eg DS mode, LS mode, CRX mode). Base station 102 can schedule and / or process data transmissions between base station 102 and the mobile device (eg 116) when the mobile device is in a linked period (eg, bound partition), except that while in mode DS the mobile device (for example, 116) cannot exchange data with base station 102, but can exchange control information with base station 102.
Each of DS mode, LS mode and CRX mode can be additionally configured based in part on
17/49 respective CQI attributes, respective sound reference signal (SRS) attributes, respective measurement events, and / or respective timer values, where the timer values can be used to facilitate the determination of when the mobile device ( for example, 116) must transition from one mode to another mode. For example, CQI attributes can be configured or updated based in part on the type of standby mode, or transition from one standby mode to another standby mode.
With regard to pre-defined standby criteria, such criteria can relate, for example, to an explicit signal (for example, control message) from base station 102 indicating and / or orienting the mobile device (for example, example 116) to transition from one mode to another mode (for example, from LS mode to DS mode) and / or an implicit signal (for example, lack of data communication associated with the mobile device for a predetermined period of time or more). The mobile device (eg 116) can monitor and analyze information received, such as control messages, data messages, and / or information regarding the length of time between events (for example, receiving or sending a data transmission or information from control) and / or the type of events that occur, and you can control the selection of, and / or switching between, the different modes based in part on the predefined standby criteria. 0 mobile device (eg 116) can also track the time span between events to facilitate the determination of whether the predetermined time period elapsed between specific events in order to trigger a transition from one mode to another mode. The mobile device (for example, 116) can transition
18/49 for LS mode or DS mode based in part on predefined standby criteria to facilitate the reduction of energy consumption. As a result, the mobile device (eg 116) can facilitate a reduction in energy consumption compared to conventional mobile devices.
In one aspect, when the mobile device (for example, 116) is in DS mode, an implicit signal to transition from DS mode to LS mode may include receiving information regarding a downlink data transmission such as scheduling a data transmission. downlink data from base station 102 to the mobile device (eg 116) or access or schedule an uplink data transmission (eg scheduled uplink transmission) and after any of the events mentioned above have occurred, the predefined standby criteria may indicate that the mobile device should transition from DS mode to LS mode. The mobile device (e.g. 116) can transition from DS mode to LS mode after any such event (s) has occurred based in part on predefined standby criteria.
If in DS mode, a mobile device (for example, 116) can still transmit uplink control signals at predefined time events (for example, during connected periods). The mobile device (for example, 116) can also remain in DS mode if it receives special control information via the control channel (for example, PDCCH). For example, while in DS mode, the mobile device (eg 116) can receive power control information, Layer 1 (eg physical layer) / Layer 2 control channel message (eg, link layer) (L1 / L2), or commands
19/49
Up down. For example, when the mobile device (eg 116) receives information, the mobile device (eg 116) can signal to base station 102 that only the L1 / L2 control is successfully decoded (for example, where transmission of downlink data is not successfully decoded), and the signal can be a negative acknowledgment (NAK); or the mobile device can signal that both the L1 / L2 control and the programmed downlink (for example, data) are successfully decoded, which can be an acknowledgment (ACK).
As an example of another implicit signal, while the mobile device (eg 116) is in LS mode, if the mobile device does not exchange (for example, transmit and / or receive) data with base station 102 for a predetermined period of time , the predefined standby criteria can specify that the mobile device should transition from LS mode to DS mode and the mobile device can switch from LS mode to DS mode, to facilitate the reduction of energy consumption on the mobile device. The mobile device (for example, 116) can be configured in such a way that the implicit signals for the transitions from DS mode to LS mode, and from LS mode to DS mode, associated with DRX may correspond to or be limited with the transitions from DS mode to LS mode, and from LS mode to DS mode, associated with DTX, or the transitions respectively associated with DRX and DTX can be configured without regard to each other. Where the mobile device (for example, 116) is accessing in DS mode associated with DRX, the mobile device is typically not able to transition out of DS mode until it receives implicit or explicit confirmation regarding access from the base station 102 .
Yet another example of an implicit signal can be
20/49 relate to the transition between CRX mode and LS mode. While the mobile device (eg 116) is in CRX mode, if the mobile device (eg 116) does not exchange (eg transmit and / or receive) data with base station 102 for a predetermined period of time, predefined standby criteria can specify that the mobile device should transition from CRX mode to LS mode, and the mobile device can switch from CRX mode

an L1 / L2 control message and a programmed data downlink (for example, L1 / L2 + DL SCH control channel), sent from base station 102 to the mobile device (for example, 116), where the predefined criteria standby mode can provide that after receiving such an explicit signal, the mobile device must transition from DS mode to LS mode (for example, with respect to DRX and / or DTX), and the mobile device can transition from mode DS for LS mode. An explicit signal can be generated by base station 102 and sent to the mobile device (eg 116) for example, when base station 102 knows that there will be no data exchange, and / or no data exchange, between the station base 102 and the mobile device for a predefined period of time based in part on the predefined standby criteria. Base station 102 can also track the amount of time that has elapsed between data exchanges with the mobile device (e.g. 116) to facilitate determining whether a predefined time period has elapsed between data exchanges.
As another example of an explicit signal, an explicit signal can also include an
21/49 L1 / L2 control, and / or an L1 / L2 control message and a programmed data downlink, sent from base station 102 to the mobile device (for example, 116), where the predefined waiting can provide that after receiving such an explicit signal, the mobile device must transition from LS mode to DS mode (for example, with respect to DRX and / or DTX) and the mobile device can transition from LS mode to DS mode .
Another example of an explicit signal may relate to the transition from / to CRX mode to / from LS mode or DS mode. Such an explicit signal may include an L1 / L2 control message, and / or an L1 / L2 control message and a programmed data downlink, sent from base station 102 to the mobile device (eg 116), where predefined standby criteria may provide that after receiving such an explicit signal, the mobile device must transition from / to CRX mode to / from LS mode or DS mode (for example, with respect to DRX and / or DTX ), and the mobile device can transition from / to CRX mode to / from the desired mode (for example, LS mode, DS mode), as specified in the message that provides the explicit signal.
In another aspect, the mobile device (for example, 116) can be configured to send CQI information. The CQI offset can vary from 0 to several partitions, for example. It may be desirable to synchronize uplinks when sending CQI information. CQI cannot typically be sent if the off period (for example, associated with XRD) is a significant period of time (for example, 2 seconds or more) and there is a possibility of losing synchronization. It may also be desirable to be controlled by energy when sending CQI information, as there may be little benefit from sending CQI if
22/49 the probability of successful decoding at base station 102 is low. To facilitate energy control, an additional broadband reference signal can be provided with CQI. For example, SRS can be employed when sending CQI from the mobile device (for example, 116) to base station 102. CQI information can be used by base station 102 to facilitate determining the appropriate data transmission rates between base station 102 and the mobile device (for example, 116), as a channel with a higher quality indicator can typically support a higher data transmission rate than a channel with a lower quality indicator.
In one embodiment, the mobile device (for example 116) can employ CRX mode, LS mode, and DS mode (for example, DRX and / or DTX). Such a modality of the present innovation can result in a substantial reduction in energy consumption by the mobile device (for example, 116) compared to conventional mobile devices, while also providing appropriate support for certain applications, such as games or Internet Voice Protocol (VoIP) , for example. The mobile device can transition between LS mode and DS mode (for example, DRX and / or DTX) based in part on explicit signaling and / or implicit signaling. Explicit signaling can also be used to facilitate the transition to and / or from CRX mode (for example, with respect to DRX and / or DTX).
According to another embodiment, the mobile device (for example, 116) can employ CRX mode and LS mode (for example, DRX and / or DTX). As a result, there may be a reduction in energy consumption (for example, by transitioning to LS mode) by the mobile device (for example, 116) compared to mobile devices
Conventional 23/49, while also providing appropriate support for certain applications, such as games or VoIP, for example. Transitions between CRX mode and LS mode can be performed using explicit signaling and / or implicit signaling.
According to yet another embodiment, the mobile device (for example, 116) can employ CRX mode and DS mode (for example, DRX and / or DTX). As a result, there can be a significant reduction in energy consumption (for example, by transitioning to DS mode) by the mobile device (for example, 116), compared to conventional mobile devices. Transitions between CRX mode and DS mode can be performed using explicit signaling and / or implicit signaling, for example.
Referring to figure 2, a system 200 is illustrated that can facilitate transitions between different standby modes associated with a mobile device in a wireless communication environment. System 200 includes a base station 102 that can communicate with one or more mobile devices, such as mobile device 116. It should be recognized and understood that only one mobile device is represented in figure 2 for clarity and brevity. In addition, base station 102 can communicate with other base station (s) and / or any different devices (for example, servers) (not shown) that can perform functions such as authentication, authorization, accounting, billing, and so on. The base station 102 and mobile device 116 can be individually the same or similar to, respectively, and / or can respectively comprise the same or similar functionality as respective components as described more fully here, as, for example, with respect to system 100.
24/49
The mobile device 116 can be connected communicatively (e.g., wirelessly) to the base station 102, where the connection can comprise a data channel and a control channel. The data channel can facilitate data transmission between the mobile device 116 and the base station 102, and the control channel can facilitate the transmission of control information between the mobile device and the base station 102.
In one aspect, the mobile device 116 may include a standby mode controller 202 that can facilitate the transition of the mobile device 116 between the various standby modes, such as DS mode, LS mode and / or CRX mode (for example, with DRX and DTX) based in part on predefined standby criteria that can be stored in data storage 204. 0 standby controller 202 can facilitate retrieving information associated with predefined from data store 204, and can provide predefined standby criteria for an analyzer component 206 that can evaluate information received regarding activity (e.g., data exchanges associated with the mobile device 116) and can compare such received information with the predefined standby criteria to facilitate the determination of whether the mobile device 116 should transition from one mode to another mode.
It will be recognized that the data storage 204 described herein may be volatile or non-volatile memory, or may include both volatile and non-volatile memory. As an illustration and not a limitation, non-volatile memory may include read-only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable PROM (EEPROM), flash memory, and / or
25/49 non-volatile random access memory (NVRAM). Volatile memory can include random access memory (RAM), which can act as external cache memory. As an illustration and not a limitation, RAM is available in many forms as
Synchronous RAM (SRAM), Dynamic RAM (DRAM), Synchronous DRAM (SDRAM), Dual Data Rate SDRAM (DDR SDRAM), Enhanced SDRAM (ESDRAM), DRAM Synchlink (SLDRAM) and Direct Rambus RAM (DRRAM). The memory 608 of the present systems and methods is intended to understand, without being limited to, these and any other appropriate types of memory.
mobile device 116 may also include a timer 208 which can track the time elapsed between the occurrence of events, such as, for example, the time elapsed between data exchanges associated with the mobile device 116. Timer 208 can provide information regarding the elapsed time between events to the standby controller 202 and / or analyzer 206 to facilitate the determination of whether the mobile device 116 was inactive with respect to data exchanges for a predetermined period of time or greater, where such a predetermined period of time can be specified by predefined standby criteria, and where there may be different predetermined periods of time employed with respect to different types of transitions (for example, a predetermined period of time associated with determining whether to transition from CRX mode to LS mode; a different predetermined period of time associated with determining whether to transition between LS mode and DS mode) and / or different types of transmissions (for example, data reception, data transmission).
For example, mobile device 116 may be in CRX mode, and analyzer component 206 may receive
26/49 time information from timer 208 indicating that there was no data exchange between the mobile device 116 and the base station 102 for two seconds. The analyzer 206 can compare this time information with the predefined standby criteria, which in this example, can specify that the mobile device 116 must be transitioned from CRX mode to LS mode if two or more seconds have elapsed since the last data exchange. Analyzer 206 can determine that predefined standby criteria have been met to transition from CRX mode to LS mode, and can communicate that determination to standby controller 202. Standby controller 202 can facilitate transition (e.g., switching) from the mobile device 116 from CRX mode to LS mode based in part on the predetermined standby mode determination and / or criteria. The elapsed time that meets the predefined criteria of standby mode for transition from CRX mode to LS mode can be an implicit signal to perform such a transition.
As another example, a mobile device 116 may be in LS mode. The mobile device 116 can receive an explicit signal, such as an L1 / L2 control channel or L1 / L2 + DL SCH control, from the base station 102 which indicates that the mobile device 116 must transition from LS mode to the DS mode. Such a message can be provided to analyzer 206, which can compare the received message with the predefined standby criteria, where such criteria can specify that a transition from LS mode to DS mode should be performed after receiving such a message, and the Analyzer 206 can determine that there must be a transition from LS mode to DS mode. Analyzer 206 can communicate this determination
27/49 to the standby controller 202, and the standby controller 202 can facilitate the transition of the mobile device 116 from LS mode to DS mode.
Referring now to Figure 3, a system 300 is illustrated which can facilitate transitions between different standby modes associated with a mobile device in a wireless communication environment. System 300 includes a base station 102 that can communicate with one or more mobile devices, such as mobile device 116. It should be recognized and understood that only one mobile device is represented in figure 3 for clarity and brevity. In addition, base station 102 can communicate with other base station (s) and / or any different devices (for example, servers) (not shown) that can perform functions such as authentication, authorization, accounting , billing, and so on. The base station 102 and mobile device 116 can individually be the same or similar to, respectively, and / or can respectively comprise the same or similar functionality to respective components as described more fully here, such as, for example, with respect to system 100 and / or system 200.
Base station 102 may include a controller 302 that can facilitate control of transitions between various standby modes on mobile device 116. For example, controller 302 in combination with analyzer 304 can facilitate the evaluation and / or comparison of information relevant to transition determinations in view of the predefined standby criteria to facilitate the determination of whether to generate and send an explicit signal ( for example, control message) for mobile device 116 directing mobile device 116 to transition from one standby mode to another mode.
28/49
Base station 102 can also include a timer 306 that can track the amount of time that has elapsed between data exchanges, or from the last data exchange, between base station 102 and mobile device 116. 0 timer 306 can provide that time information to controller 302 and / or analyzer 304, and that time information can be evaluated (for example, compared) against predefined standby criteria to facilitate determining whether a transition should be performed.
Base station 102 can also comprise a programmer 308 that can program uplink and / or downlink transmissions between base station 102 and mobile device 116. Programmer 308 can program that downlink transmissions occur when mobile device 116 is in a period or on state (for example, on period of LS mode, or CRX mode that can be in a continuous on state). Programmer 308 can also schedule uplink transmissions to occur when the mobile device 116 is in an on period (for example, LS mode on period, or CRX mode which can be in a continuous on state). Programmer 308 can facilitate the transmission of desired control messages and / or associated data as part of the specific transmission.
With reference to figures 4-5, methodologies regarding the selection of standby modes and / or transition between standby modes associated with a mobile device in a wireless communication environment are illustrated. While, for the sake of simplicity of explanation, the methodologies are shown and described as a series of acts, it must be understood and recognized that the methodologies are not limited by the order of acts, since some acts may, according to one or more modalities , occur in
29/49 different orders and / or simultaneously with other acts from the one shown and described here. For example, those skilled in the art will understand and recognize that a methodology could alternatively be represented as a series of interrelated states or events, as in a state diagram. In addition, not all illustrated acts may be necessary to implement a methodology according to one or more modalities.
With reference to figure 4, a methodology 400 is illustrated that can facilitate the selection of a standby mode on a mobile device associated with a wireless communication system. In 402, a standby mode can be selected based in part on a predefined standby criterion. In one aspect, the standby modes available for selection can include an LS mode, a DS mode, and / or a non-standby mode (for example, CRX mode). 0 mobile device can facilitate selection of the desired standby mode. At 404, there may be a signal to facilitate selection of the standby mode. For example, signaling can be an explicit signaling, such as a control message from the base station (for example, 102) to a mobile device (for example, 116), instructing the mobile device to transition from a standby mode to another standby mode by selecting another standby mode; or it can be an implicit signal that can be based in part on a condition being met, such as a predetermined period of time that elapses between the last data exchange between the base station and the mobile device, where the condition (s) can be defined by predefined standby criteria, for example.
Going back to figure 5, a 500 methodology is illustrated that can facilitate the transition to a
30/49 standby on a mobile device associated with a wireless communication system. At 502, information related to a standby mode (s) can be evaluated. In one aspect, an analyzer associated with a mobile device (eg 116) or a base station (eg 102) can evaluate information related to standby modes, such as information related to the time period elapsed since the last data exchange between the base station and mobile device. In 504, a determination can be made as to whether a transition from a first standby mode to another standby mode should be performed, based in part on predefined standby criteria. For example, the analyzer can make a determination as to whether to transition from an LS mode to a DS mode after evaluating received information related to standby modes and comparing such received information with predefined standby criteria to determine whether a transition condition has been met. In 506, there may be a signal to facilitate a transition from the first standby mode to another standby mode. For example, if it is determined that a transition condition has been met based in part on the information received and / or the predefined standby criteria, an explicit and / or implicit signal can be generated to facilitate the transition from the first mode. to another standby mode. An explicit signaling can be a control message from the base station to the mobile device indicating that the mobile device must transition from the first standby mode to another standby mode. An implicit signaling can be, for example, a certain condition related to the predefined standby criterion being met, where the given condition being met can indicate (for example, signal
31/49) for the mobile device and / or base station that the mobile device must transition from the first standby mode to another standby mode. In 508, there may be a transition from the first standby mode to the other standby mode. For example, the signal may indicate that the mobile device must transition from the first standby mode (for example, LS mode) to another standby mode (for example, DS mode).
It will be recognized that, according to one or more aspects described here, inferences can be made regarding the selection of standby modes and / or determining when to transition between standby modes with respect to a mobile device. As used here, the term infer or inference generally refers to the process of reasoning about or inferring states of the system, environment and / or user from a set of observations as captured through events and / or data. Inference can be used to identify a specific context or action, or it can generate a probability distribution across states, for example. The inference can be probabilistic - that is, the computation of a distribution of probabilities through states of interest based on a consideration of data and events. Inference can also refer to techniques used to compose higher level events from a set of events and / or data. Such inference results in the construction of new events or actions from a set of observed events and / or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or more sources. data and events.
According to an example, one or more of the methods presented above may include making an inference (s)
32/49 pertinent to the selection of a standby mode and / or transition from one standby mode to another standby mode. As an additional illustration, an inference (s) can be made regarding the determination of whether a transition between a standby mode and another standby mode should be performed or has occurred. It will be recognized that the examples above are of an illustrative nature and are not intended to limit the number of inferences that can be made or the way in which such inferences are made in combination with the various modalities and / or methods described here.

substantially similar or different to the example base station 810 and mobile device 850 described below. In addition, it must be recognized that the base station 810 and / or mobile device 850 may employ the systems (figures 13, 6-7 and 9-10) and / or methods (figures 4-5) described here to facilitate wireless communication between them. It should be recognized that the base station 810 and mobile device 850 can individually be the same or similar to, respectively, and / or can comprise respectively the same or similar functionality to, respective components as described more fully here, as, for example, with respect to to system 100, system 200, system 300, system 600 and / or system 700.
At the base station 810, traffic data for various data streams is provided from a data source 812 to a transmission data processor (TX) 814. According to an example, each data stream can be transmitted via respective antenna. The TX 814 data processor formats, encodes and merges the traffic data stream based on a specific coding scheme selected for that data stream to provide encrypted data.
The encoded data for each data stream can be multiplexed with pilot data using
39/49 orthogonal frequency division (OFDM) multiplexing techniques. Additionally or alternatively, the pilot symbols can be multiplexed by frequency division (FDM), multiplexed by time division (TDM), or multiplexed by code division (CDM). Pilot data is typically a known data standard that is processed in a known manner and can be used on the mobile device 850 to estimate channel response. The encoded data and multiplexed pilots for each data stream can be modulated (for example, mapped in symbols) based on a specific modulation scheme (for example, binary phase switching manipulation (BPSK), phase switching manipulation in quadrature (QPSK), por phase shift manipulation (MPSK), M quadrature amplitude modulation (M-QAM), etc.) selected for that data stream to provide modulation symbols. The data rate, encoding and modulation for each data stream can be determined by instructions executed or provided by the 830 processor.
The modulation symbols for the data streams can be provided to a MIMO TX 820 processor, which can additionally process the modulation symbols (for example, for OFDM). The MIMO TX 820 processor then provides N<sub>T</sub> modulation symbol streams for N<sub>T</sub> transmitters (TMTR) 822a up to 822t. In various modalities, the MIMO TX 820 processor applies beamforming weights to the symbols of the data streams and to the antenna from which the symbol is being transmitted.
Each transmitter 822 receives and processes a respective symbol stream to provide one or more analog signals, and further conditions (for example, amplifies, filters, and upwards converts) the analog signals
40/49 to provide a modulated signal suitable for transmission over the IMO channel. In addition, N modulated signals<sub>T</sub> from transmitters 822 to 822t are transmitted from N antennas<sub>T</sub> 824a to 824t, respectively.
On the 850 mobile device, the transmitted modulated signals are received by N antennas<sub>G</sub> 852a through 852r and the signal received from each antenna 852 is supplied to a respective receiver (RCVR) 854a through 854r. Each receiver 854 conditions (e.g., filters, amplifies and downwards converts) a respective signal, digitizes the conditioned signal to provide samples, and further processes the samples to provide a corresponding received symbol stream.
An RX 860 data processor can receive and process the received symbol streams N<sub>g</sub> from N receivers<sub>g</sub> 854 based on a specific receiver processing technique to provide N<sub>t</sub> detected symbol streams. The RX 860 data processor can demodulate, deinterleave and decode each detected symbol stream to retrieve traffic data for the data stream. The processing by the RX 860 data processor is complementary to that performed by the MIMO TX 820 processor and TX 814 data processor at the base station 810.
An 870 processor can periodically determine which pre-coding matrix to use (discussed below). In addition, processor 870 can formulate a reverse link message comprising a matrix index portion and a classification vapor portion.
The reverse link message can comprise various types of information regarding the communication link and / or the flow of data received. The reverse link message can be processed by a TX 838 data processor, which also receives traffic data for
41/49 several data streams from a data source 836, modulated by a modulator 880, conditioned by transmitters 854a through 854r, and transmitted back to base station 810.
At base station 810, signals modulated from mobile device 850 are received by antennas 825, conditioned by receivers 822, demodulated by a demodulator 840, and processed by an RX 842 data processor to extract the reverse link message transmitted by the device mobile 850. In addition, processor 830 can process the extracted message and can determine which pre-coding matrix to use to determine the beam formation weights.
Processors 830 and 870 can guide (for example, control, coordinate, manage, etc.) operation on base station 810 and mobile device 850, respectively. The respective processors 830 and 870 can be associated with memory 832 and 872 which stores data and program codes. Processors 830 and 870 can also perform computations to derive frequency and impulse response estimates for uplink and downlink, respectively.
In one respect, logical channels are classified into Control Channels and Traffic Channels. Logic Control Channels can comprise Broadcast Control Channel (BCCH) which is a DL channel for broadcasting system control information. Paging control channel (PCCH) which is a DL channel that transfers paging information. For example, PCCH can be used when the network does not know the UE's location cell. The common control channel (CCCH) which is a channel that can be used to transmit control information between UEs and the network. This channel can be used by UEs without a connection
42/49
RRC with the network. The Multicast Control Channel (MCCH) which is a point-to-multipoint DL channel used to transmit Multicast and Multimedia Broadcast Service (MBMS) control and programming information to one or more MTCHs. generally, after establishing RRC connection, this channel is used only by UEs that receive MBMS (Note: MCCH + old MSCH). It is observed that it is FFS as MBMS is transmitted by L2 / 3 signaling in MCCH or Ll signaling. The Dedicated Control Channel (DCCH) is a two-way point-to-point channel that transmits dedicated control information and is used by UEs having an RRC connection. In this respect, logical traffic channels can comprise a dedicated traffic channel (DTCH) which is a two-way point-to-point channel, dedicated to a UE, for the transfer of user information. A DTCH can be used in both UL and DL. In addition, a Multicast Traffic Channel (MTCH) for point-to-multipoint DL channel to transmit traffic data. This channel can be used by UEs that receive MBMS.
In one respect, transport channels are classified in DL and UL. DL Transport Channels comprise a Broadcast Channel (BCH), a Shared Downlink Data Channel (DL-SDCH), a Paging Channel (PCH)

hybrid automatic repeat request (HARQ); support for dynamic link adaptation by varying the modulation, encoding and transmission power; ability to be broadcast across the entire cell; ability to use beam formation; support for both dynamic and semi-static resource allocation; reception support
EU batch 43/49 (DRX) to allow EU energy savings; support for MBMS transmission. It is observed that the ability to use slow energy control can be based in part on the physical layer. 0 SHP can be characterized by having UE energy saving support (DRX cycle is indicated by the network for the UE); ability to be broadcast over the entire cell coverage area, and can be mapped to physical resources that can be used dynamically for traffic channels or other control channels. 0 MCH can be characterized by being able to be broadcast in the entire cell coverage area; support for combining MBSFN from multi-cell MBMS transmission; and support for semi-static resource allocation (for example, with a long cyclic prefix time frame). The UL Transport Channels comprise a Shared Uplink Channel (UL-SCH), a Random Access Channel (RACH) and a plurality of PHY channels. UL-SCH can be characterized by being able to use beam formation; support for dynamic link adaptation by varying transmission power and potentially modulation and encoding; support for HARQ; support for both dynamic and semi-static resource allocation. It is observed that the possibility of using UL synchronization and timing advance may depend in part on the physical layer. RACH can be characterized by having limited control information, and risk of collision. It is observed that the possibility of using open loop power control may depend in part on the physical layer solution. PHY channels comprise a set of DL channels and UL channels.
The PHY channels (for example, from E-ULTRA) can be: physical broadcast channel (PBCH), the coded BCH transport block can be mapped to four
44/49 subframes over a 40 ms interval, 40 ms delay can be detected blindly (for example, there is no explicit signal indicating 40 ms delay), each sub frame can be assumed to be self-decoding (for example, the BCH it can be a single reception decoder, assuming sufficiently good channel conditions); physical control format indicator channel (PCFICH) that can inform the UE about the number of OFDM symbols used for PDCCHs, and can be transmitted in every subframe; physical downlink control channel (PDCCH) that can inform the US about the allocation of SHP and DL-SCH resources, and hybrid ARQ information related to DL-SCH, and may contain the granting of uplink programming; physical hybrid ARQR indicator channel (PHICH) that may contain hybrid ARQ ACK-NAKs in response to uplink transmissions; shared physical downlink channel (PDSCH) that can contain DL-SCH and PCH; physical multicast channel (PMCH) that can contain the MCH; physical uplink control channel (PUCCH) which may contain hybrid ARQ ACK / NAKs in response to downlink transmission, may contain programming (SR), and may contain CQI reports; shared physical uplink channel (PUSCH) that can contain the ULSCH; and physical random access channel (PRACH) that can contain the preamble of random access.
In one aspect, a channel structure is provided that preserves low PAR properties (at any given time, the channel is contiguous or evenly spaced in frequency) from a single carrier waveform.
It should be understood that the modalities described here can be implemented in hardware, software, firmware, middleware, microcode, or any combination thereof. For a hardware implementation, processing units can be implemented in one or more
45/49 application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable port arrangements (FPGAs), processors, controllers, microcontrollers, microprocessors, other electronic units designed to perform the functions described here, or a combination thereof.

6/49 processor through various means as known in the art.
Referring to figure 9, a system 900 is illustrated that can facilitate transitions between different standby modes on a mobile device associated with a wireless communication environment. For example, the 900 system can reside at least partially on a mobile device (for example, 116) It should be recognized that the 900 system is represented as including function blocks, which can be function blocks that represent functions implemented by a processor, software, or combination thereof (for example, firmware). System 900 includes a logical grouping 902 of electrical components that can act in combination.
For example, logical grouping 902 may include an electrical component to select a standby mode based in part on a predefined standby criterion, where the standby mode can be an LS mode, a DS mode or a non-standby mode (eg CRX mode) 904. For example, selecting a standby mode may involve switching from one standby mode to another standby mode. According to one aspect, the standby mode can be considered a special mode associated with the LS mode, where, for the standby mode, the off period can be set to 0, so that the mobile device (for example, 116) can be in a continuously on state. In addition, logic grouping 902 may comprise an electrical signaling component related to a 906 standby mode. For example, signaling may comprise explicit signaling (for example, control signal) and / or implicit signaling (for example, a predefined condition associated with the predefined standby criterion has been met). Additionally, the 900 system can include 908 memory
47/49 which retains instructions for performing functions associated with electrical components 904 and 906. Although shown to be external to memory 908, it should be understood that one or more electrical components 904 and 906 may exist in memory 908.
Going back to figure 10, a system 1000 is illustrated that can facilitate transitions between different standby modes in a mobile device associated with a wireless communication environment. The system 1000 can reside in a base station (for example, 102), for example. As shown, system 1000 includes function blocks that can represent functions implemented by a processor, software, or combination thereof (for example, firmware). System 1000 includes a logical grouping 1002 of electrical components that can act in combination. Logical grouping 1002 can include an electrical component to select a standby mode based in part on a predefined standby criterion, where the standby mode can be an LS mode, a DS mode, or a standby mode ( for example, CRX mode) 1004. For example, selecting a standby mode may involve switching from one standby mode to another standby mode on a mobile device (for example, 116) associated with the base station. According to one aspect, the standby mode can be considered a special mode associated with the LS mode, where, for the standby mode, the off period can be set to 0, so that the mobile device (for example, 116) can be in a continuously on state. In addition, logic grouping 1002 may comprise an electrical signaling component related to a standby mode 1006. For example, signaling may comprise explicit signaling (for example, control signal) and / or implicit signaling (for example, a condition
48/49 default associated with the default standby criterion has been met). In addition, logical grouping 1002 may include an electrical component for scheduling data transmissions 1008. For example, scheduling data transmissions may refer to uplink and downlink transmissions of data and / or control information between the base station and a mobile device. The scheduling of data transmissions can be such that data transmissions can be performed at times when a mobile device is in a linked period for a downlink transmission and / or a linked period for an uplink transmission. The programming of data transmissions can be based in part on the standby mode associated with the mobile device (for example, 116). In addition, system 1000 may include a memory 1010 that holds instructions for performing functions associated with electrical components 1004, 1006 and 1008. While shown to be external to memory 1010, it should be understood that one or more of electrical components 1004, 1006 and 1008 may exist in memory 1010.
What has been described above includes examples of one or more embodiments. Of course, it is not possible to describe every conceivable combination of components or methodologies for the purpose of describing the aforementioned modalities, but a person of ordinary skill in the art may recognize that many additional combinations and permutations of various modalities are possible.

Furthermore, to the extent that the term includes is used in the detailed description or claims, that term is intended to be inclusive in a similar way to the term comprising as comprising is
49/49 interpreted when used as a transitional word in a claim.
