Various embodiments relate to wireless communication, and more particularly to methods and devices that can be used to communicate low bit number data information transfers in wireless communication systems.
Location-based applications such as "Loopt" running on mobile over a wide area network require frequent updates of extremely short messages to be sent by mobile to access points, such as base stations, on uplinks. , Downlinks need to be sent to mobile by the access point. Location updates are on the order of tens of bits, but must be sent and received every few seconds, so the need for this information exchange to take place using regular wide area network traffic channels is Extremely expensive in terms of control messaging overhead. In addition to location updates, various other types of applications, such as social networking applications that utilize localized peer-to-peer communication for primary communication, communicate relatively small amounts of information relatively frequently in an efficient manner. You also need to. For example, it may be advantageous to be able to communicate a small amount of peer discovery information in the local area in such a way. For example, the number of devices that can be actively supported at a given time during the transmission of data by a so-called active mobile, which has dedicated resources, including data traffic channel resources, is relatively limited. To increase the number of devices that can be supported, WAN systems typically go to sleep, where the devices are not subject to closed-loop timing and / or closed-loop power control and also lack dedicated traffic channel resources. to support. In a typical wide area network, there can be thousands of mobiles that are "sleeping" at a given time. Sleeping mobiles typically lack a dedicated channel for traffic data and usually have a dedicated traffic channel before sending or receiving meaningful data, including very short messages of the type described above. Complex c to be able to allocate resources Must be transitioned to the "active" state by the process shaking procedure. Therefore, the overhead associated with sending short messages for sleeping devices can be significant due to the resources required to allow the transition to the active state.
Based on the above description, there is a need for methods and devices that provide efficient means of frequently communicating small amounts of information in wireless communication systems. It would be advantageous if such a method did not require a large amount of signaling overhead. Further, if some methods and devices are scalable, it would be desirable, for example, if it is possible to support an implementation with a small number of users and an implementation with a large number of users.

FIG. 14 includes illustrated 1400 of an exemplary wide area network (WAN) uplink timing frequency structure according to an exemplary embodiment. The vertical axis 1402 represents frequency, eg, OFDM tones, and the horizontal axis 1404 represents time. In some embodiments, the unit of time is the OFDM symbol transmission time interval. The WAN uplink timing frequency structure includes WAN traffic and / or control signaling airlink resource 1406, representational advertising airlink resource 1408, and WAN traffic and / or control signaling airlink resource 1410. In this embodiment, the timing frequency structure follows a circulation pattern. In this example, the expression advertising airlink resource 1408 occurs during the expression advertising interval 1412. In this example, the representational advertising airlink resource is a very small part of a set of resources that includes resource 1406, resource 1408, and resource 1410, for example, about 2% of that set.
The representational advertising airlink resource 1408 contains, in this example, a set of 16 different resources, each associated with a different representational advertising resource index (1, 2, ..., 16). In other embodiments, there are different numbers of resources in the set, and generally more resources in the set. The number of resources in the set of representational advertising resources for an access point is expected in some embodiments to be a user who can always be registered with the access point, including sleeping and active users. It has been selected to adapt to the number of resources. The number of users allowed to be active at a given time is generally much smaller than the number of users who can sleep on the access point. Also, the number of users sleeping on the access point at a given time is generally much smaller than the number of sleeping users in the paging area containing the access point and in the entire system. In one exemplary embodiment, the structure consists of 200 active users on the access point, 4000 sleep users on the access point, 5600 represented advertising resource IDs on the access point, the access point and one. Or it is structured to support 20000 paging IDs in a paging area containing multiple other access points and 10000000 wireless communication devices in a communication system. In some embodiments, the individual representational advertising airlink resources have one OFDM tone for a predetermined fixed number of OFDM symbol transmission time intervals.
In some embodiments, the signal transmitted by the wireless terminal using the Representation Advertising Airlink Resource 1408 is a signal with open loop power control. At least some signals transmitted by wireless terminals in one or more of WAN traffic and / or control airlink resources (1406, 1410) are closed-loop power control signals and / or closed-loop timing control signals. As a result, some uplink traffic signals communicated on one or more of the resources (1406, 1410) are closed-loop power controlled and / or closed-loop timing controlled signals.
In this embodiment, the location of the individual resources associated with a particular representational advertising resource index can and from time to time change at each representational advertising interval according to hopping information. Block 1408 shows the first mapping of airlink resources during the first representation ad interval 1412, and block 1408'is the thirst of the airlink resources during the subsequent representation ad interval according to an exemplary hopping function. The mapping of 2 is shown. A particular wireless terminal may collect and retain an individual representational advertising resource index and use the resources associated with that index while registered with an access point, eg, a base station. For example, the first wireless terminal may collect the Representation Advertising Resource Index 2 and use the individual resources 1414 of the Representation Advertising Resource Block 1408 and the individual resources 1416 of the Representation Advertising Resource Block 1408'.
In FIG. 15, a wireless terminal has a paging identifier associated with a paging airlink resource and a representational advertising resource identifier associated with a representational advertising airlink resource, with the representational advertising resource identifier local to the access point. FIG. 1500, wherein the paging identifier is used to indicate an exemplary embodiment applied to a paging area that includes a plurality of access points. Illustrated 1500 includes access point 1 1502, eg, base station 1, and access point 2 1504, eg, base station 2. Access point 1 1502 has a wireless coverage area represented by cell 1 1506, and access point 2 1504 has a wireless coverage area 1508 represented by cell 2 1508. Both cell 1 1506 and cell 2 1508 are within the paging area 1510.
The wireless terminal 1 1512 has a paging identifier = 30 1514, and the wireless terminal 1 1512 retains and uses the paging identifier = 30 1514 while in the paging area 1510. Consider that wireless terminal 1 1512 is registered with access point 1 1502, and that wireless terminal 1 1512 has a locally represented advertising resource identifier = 2 for access point 1 1502, as indicated by block 1516. The wireless terminal 1 1512 sends an uplink representation ad signal 1518 to access point 1 1502 using the representation advertisement airlink resource associated with the representation advertisement airlink resource index = 2 for access point 1 1502. The WT1 1512 may be sleeping or active with respect to access point 1 1502 when transmitting signal 1518.
Next, consider that wireless terminal 1 1512 moves from cell 1 1506 to cell 2 1508, as indicated by the dashed arrow 1520. As part of that move, a handoff will take place and wireless terminal 1 1512 will collect a new locally represented advertising resource identifier corresponding to access point 2 1504. In this example, wireless terminal 1 1512 collects a representational advertising resource identifier = 3 for access point 2 1504, as indicated by block 1522. The wireless terminal 1 1512 sends an uplink representation ad signal 1524 to access point 2 1504 using the representation advertisement airlink resource associated with the representation advertisement airlink resource index = 3 for access point 2 1504. The WT1 1512 may be sleeping or active with respect to access point 2 1504 when transmitting signal 1524.
FIG. 16 is a diagram showing an uplink representation advertising interval and a corresponding downlink representation broadcast interval according to an exemplary embodiment. Illustrated 1600 in FIG. 16 includes an exemplary access point 1 1602, eg, base station 1, and a plurality of wireless terminals (wireless terminal 1 1604, wireless terminal 2 1606, wireless terminal 3 1608). Illustration 1610 shows a portion of an exemplary uplink timing frequency structure used by access point 1 1602 and wireless terminals (1604, 1606, 1608). Illustration 1612 shows a portion of an exemplary downlink timing frequency structure used by access point 1 1602 and wireless terminals (1604, 1606, 1608).
The uplink timing frequency structure of 1610 in the figure includes a frequency, eg, a vertical axis 1614 representing an OFDM tone and a horizontal axis 1616 representing time. The uplink timing includes the expression ad interval 1618, and there is a set of expression advertisement airlink resources 1620 in the expression advertisement interval 1618.
The downlink timing frequency structure of FIG. 1612 includes a frequency, eg, a vertical axis 1622 representing an OFDM tone and a horizontal axis 1624 representing time. Its downlink timing includes the representation broadcast interval 1626, and within the representation broadcast interval 1626 there is a set of representation broadcast airlink resources 1628.
Each of the wireless terminals (WT1 1604, WT2 1606, WT3 1608) has a different representational advertising resource index. The WT1 representational advertising resource index maps to individual proprietary representational advertising airline resources 1632 in the set of resources 1620. The WT2 representational advertising resource index maps to individual proprietary representational advertising airline resources 1636 in the set of resources 1620. The WT3 representational advertising resource index maps to individual dedicated representational advertising airline resources 1640 in the set of resources 1620.
During the representational advertising interval 1618, (WT1 1604, WT2 1606, WT3 1608) each use the representational advertising signals (1632, 1636, 1640) to carry the representations (E1, E2, E3), respectively. Send 1630, 1634, 1638) to access point 1 1602.
In this example, the representation broadcast interval 1626 corresponds to the representation advertisement interval 1618, and the representation broadcast airlink resource set 1628 corresponds to the representation advertisement airlink resource set 1620. In this particular embodiment, the broadcast of the representation broadcast interval is an echoback of the information received during the representation advertisement interval. Access point 1 1602 broadcasts signals (1642, 1646, 1650) using resources (1644, 1648, 1652) that carry representations (E1, E2, E3), respectively. In this example, the location of a particular resource in the set 1620 of the representation advertising airlink resource and the location of the corresponding resource in the set 1628 of the representation broadcast airlink resource have the same relative location. In other embodiments, the relative positions of the corresponding resources differ between the representational advertising interval and the representational broadcast interval, and the mapping may be known to the access point and the wireless terminal.
The broadcast signal from the representation broadcast interval signal can be received and processed by wireless terminals (WT1 1604, WT2 1606, WT3 1608). A pair of individual wireless terminals may be in a state where, for example, terrain, obstacles, etc. may not be able to successfully receive and restore each other's uplink representation advertising interval signaling. .. However, for example, the antenna location and / or receiver / transmit capability of access point 1 is generally better than the antenna location and / or receiver / transmit capability of the wireless terminal, so the wireless terminal is access point 1. It is likely that you will be able to communicate well with the 1602. Therefore, the information sent by the wireless terminal at the representation advertising interval 1618 is likely to be successfully restored by another wireless terminal via the downlink representation broadcast interval signaling communicated by the access point. In addition, it can be observed that there are multiple individual representational advertising airlink resources that occur simultaneously during the representational advertising interval 1618. When a wireless terminal is transmitting its own uplink representation advertising signal, the wireless terminal cannot restore the representation advertisement signal from other wireless terminals that may be transmitting at the same time. The use of the representation broadcast interval 1626 allows the restoration of representations from other wireless terminals that may be scheduled to use time-simultaneous resources during the representation advertisement interval.
The example of FIG. 16 shows an access point, eg, a base station, that echoes back information received in a representational advertising airlink resource in the corresponding representational broadcast interval airlink resource. Such access points can be considered dam access points. In some other embodiments, the access point interprets bits of information received during the representation advertisement interval and selectively relays the information during the representation broadcast interval 1626. Such access points can be considered intelligent access points. In some embodiments where the access point makes a selection decision regarding the rebroadcast of information received during the representation broadcast interval, the size of the representation advertisement interval airlink resource and the size of the representation broadcast interval airlink resource may differ. , Sometimes different.
FIG. 17 shows an exemplary representational advertising airlink resource block 1708 and one or more corresponding representational broadcast interval airlink resource blocks (1760, 1762). Illustration 1700 of FIG. 17 shows an exemplary frequency vs. time plot of the uplink. The illustrated 1700 includes a frequency, eg, a vertical axis 1702 representing an OFDM tone and a horizontal axis 1704 representing time. Plot 1700 includes the representation ad airlink resource block 1708 that occurs during the representation advertisement interval 1706 in the uplink timing structure. Illustration 1750 of FIG. 17 shows an exemplary frequency vs. time plot of the downlink. The illustrated 1750 includes a frequency, eg, a vertical axis 1752 representing an OFDM tone, and a horizontal axis 1754 representing time. Plot 1750 shows the first representation broadcast interval that occurs during the representation broadcast interval 1756 in the downlink timing structure and the optional second representation broadcast that occurs during the representation broadcast interval 1758 in the downlink timing structure. Includes interval airlink resource block 1762.
In some embodiments, the information transmitted by the access point in the representation broadcast interval airlink resources 1760 and 1762 is a copy of the information received by the access point in the representation advertisement interval airlink resource 1708. In some other embodiments, the information transmitted by the access point in the representation broadcast interval airlink resources 1760 and 1762 is a processed version of the information received by the access point in the representation advertisement interval airlink resource 1708, eg. , A selected subset of the information received.
In various embodiments, the same information is transmitted by the access point in the representation broadcast interval airlink resource 1760 and the representation broadcast interval airlink resource 1762. In some embodiments, in addition to the blocks 1760 and 1762 corresponding to the representational advertising airlink resource block 1708, there are additional representational broadcast interval airlink resource blocks.
The example of FIG. 17 shows that, in some embodiments, the downlink rebroadcast rate is higher than the uplink rate for the representational information. In general, access points, which are fixed location nodes that use line power, may not be as power-reduced as battery-powered wireless terminals, such as mobile nodes. A further advantage of multiple rebroadcasts of received representational information is that the discovery operation by the wireless communication device tends to be faster, for example, the peer-to-peer discovery operation tends to be faster.

Plot 1800 includes the representation advertisement airlink resource block 1808 that occurs during the representation advertisement interval 1806 in the uplink timing structure. Illustration 1850 of FIG. 18 shows an exemplary frequency-to-time plot of the access point downlink. The illustrated 1850 includes a frequency, eg, a vertical axis 1852 representing an OFDM tone and a horizontal axis 1854 representing time. Plot 1850 shows the representation broadcast interval airlink resource block 1860 that occurs during the representation broadcast interval 1856 in the downlink timing structure and the neighbor representation broadcast interval airlink resource block 1862 that occurs during the representation broadcast interval 1858 in the downlink timing structure. And include.

In the example of FIG. 18, a wireless terminal using an access point is capable of restoring expressive advertising information corresponding to a wireless terminal using the same access point via the express broadcast interval airlink resource 1860. In addition, the wireless terminal using the access point can restore the verbal advertising information corresponding to the wireless terminal using at least one neighboring access point via the neighbor representation broadcast interval airlink resource 1862.

Each of the access points mentioned with respect to FIGS. 14-21 implements the method according to Flowchart 200 and / or Flowchart 800 of FIG. 2 and / or of FIG. 3, FIG. 4, FIG. 9 and / or FIG. It can be an access point implemented according to any of the descriptions. Each of the wireless terminals referred to with respect to FIGS. 14-21 implements the method according to Flowchart 500 and / or Flowchart 1100 of FIG. 11 and / or of FIG. 6, FIG. 7, FIG. 12 and / or FIG. It can be a wireless communication device implemented according to any of the descriptions. The structure described in any of FIGS. 14-21 can be used in any of the devices described with respect to FIGS. 2-13.
Next, various features of some exemplary embodiments will be described. The access point has a representational advertising interval, eg, a peer advertising interval, in its timing structure. There are expressive ad airlink resources during the expressive ad interval. Representational advertising Airlink resources include a set of communication resource units, such as a set of OFDM tone symbols. A set of resource units, such as a set of OFDM tone symbols of a given size, is dedicated to each of the wireless terminals, eg, peers, registered on the wide area network at the access point.
Registered wireless devices, such as mobiles, may use a dedicated set of resource unit wireless devices during the representation ad interval, whether they are sleeping or active for the access point. .. A dedicated set of resource units allocated to registered wireless terminals during the representational advertising interval allows the wireless terminal to communicate a relatively small amount of information, eg, 128 information bits, to the access point. This information is communicated very efficiently with low overhead using a dedicated set of resource units.
The expressive ad interval is a relatively high rate compared to the rate at which a sleeping wireless device wakes up, eg, to update paging-related information and / or to perform other actions. Circulates in the timing structure. For example, a verbal ad interval can occur once per second, and wakeup from sleep can occur once every 30 minutes or once every hour. Wake up from sleep and subsequent communications include access hands that include significant overhead signaling, such as closed-loop timing and power control signaling, authentication, link establishment, uplink traffic resource collection, and data uplinks in traffic channels. May require shaking.
The registered wireless terminal transmits information in a dedicated set of registered wireless terminals of the resource unit of the expression advertising interval. For example, a registered wireless terminal, in some embodiments, communicates information for updating its location information. Alternatively or additionally, a dedicated set of representational ad interval resource units, in some embodiments, communicates other information, such as other low latency, low bitrate information, to the access point by a registered wireless terminal. Used to do.
In some embodiments, within a plurality of sets of resources, a dedicated set of resources dedicated to the registered wireless terminal is chronologically represented at ad intervals according to hopping functions known to the access point and the registered wireless terminal. Can change to, and changes from time to time.
In some embodiments, the wireless terminal collects a representational advertising resource identifier when it registers with the access point, and the representational advertising resource identifier is that particular wireless while the wireless terminal remains registered with the access point. Valid locally on the terminal. However, if the wireless terminal moves and, for example, hands off to another access point, the wireless terminal registers with the new access point and collects new representational advertising resource identifiers that are locally valid on the new access point. In contrast, wireless terminals may collect paging identifiers that are valid in a paging area that contains multiple access points.
In some embodiments, different access points may have different representational ad intervals and / or different repeat rates for expressive ad intervals. In some embodiments, the amount of resources allocated to the representation ad interval in the WAN uplink timing frequency structure is a function of the expected traffic load on the access point, for example, for a high traffic load representation ad interval. Less resources are allocated. In some embodiments, the amount of resources and / or repeat rate for the representation ad interval is a function of the need to use those representation ad airlink resources. For example, consider that a representational advertising resource is used to carry location information. The repeat rate can be selected as a function of the expected repositioning rate of the wireless terminal using the access point, for example, the access point is in a state of covering the inside of a shopping mall where the wireless terminal changes position fairly slowly. In some cases, the repeat rate may be low. However, the repeat rate may be higher if the access point is in a state of covering the area including the highway where the wireless terminal may be in the vehicle traveling at a relatively high rate.
In some embodiments, a wireless terminal, eg, a mobile node, may be simultaneously registered with multiple access nodes in its local vicinity. In such a situation, the wireless terminal may transmit expressive advertising information, eg, location information, at multiple expressive ad intervals, each interval where the wireless terminal is currently registered and dedicated expressive ad airlink resources. Corresponds to the collected different access points in the vicinity of the wireless terminal.
Like the representational advertising interval, each access point also has an associated representational broadcast interval. There is a representation broadcast airlink resource during the representation broadcast interval. Representation A broadcast airlink resource contains a set of communication resource units, such as a set of OFDM tone symbols. A set of resource units, such as a set of OFDM tone symbols of a given size, is dedicated to each of the wireless terminals, eg, peers, registered on the wide area network at the access point.
The access point broadcasts information obtained from the representation advertisement interval for wireless devices that may be listening during the representation broadcast interval on the downlink, such as peers. In some embodiments, this information is a copy of the information received during the peer advertising interval. In some other embodiments, the information communicated in the representation broadcast interval is a function of the information received in the representation advertisement interval. The structure of the representational advertising interval and the structure of the representational broadcast interval are the same in some embodiments. In some other embodiments, the structure of the representational advertising interval and the structure of the representational broadcast interval are different.
In some embodiments, different access points can have different representational broadcast intervals. In some embodiments, different access points have representational broadcast intervals that repeat at different rates. In some embodiments, different access points have representational broadcast intervals that occur at different times.
Registered wireless terminals, including sleeping wireless terminals, such as peers, have knowledge of the timing of the representation advertising interval and the representation broadcast interval corresponding to the access point to which the registered wireless terminal is registered. In some embodiments, the wireless terminal has knowledge of the timing of the representational advertising interval and the representational broadcast interval of access points in its vicinity.
In some embodiments, the access point may choose to forward the information received during its representational advertising interval to the server. In various embodiments, the access point can acquire expressive advertising information corresponding to other access points in the vicinity thereof. That information receives representational information communicated from one access point to another access point by listening to the representational broadcast intervals of other access points in the vicinity of the access point and / or over the backhaul network. By doing so, it can be acquired by the above access point. In various embodiments, the access point is capable of transmitting the acquired advertising information corresponding to the neighboring access point at the neighbor representation broadcast interval of its downlink timing structure.
One benefit of the exemplary method is for each wireless device that is in a "sleep" state, eg, a wireless device that wants to participate in an advertising mechanism, such as a location update mechanism, including peers, eg mobile. A dedicated low latency, low overhead channel is assigned. This enables efficient and scalable information distribution, such as location update information distribution.
