Wireless transmission/reception unit (WTRU) and integrated circuit (IC)
This creation is related to a wireless communication system including a wireless transmission/reception unit (WTRU) and at least Node B. More specifically, this creation is a method and device for selectively enabling downlink (DL) enhanced uplink (EU) signal channel reception established between the wireless transmission/receiving unit and the Node B.
In the R6 version of the third-generation mobile communications project (3GPP), methods for improving uplink (UL) coverage, processing capabilities, and transmission latency have been studied. In order to successfully implement these methods, the scheduling and allocation of uplink radio resources has been moved from a radio network controller (RNC) to a node B. Therefore, even if the radio network controller maintains all over the node B Control, the Node B can make decisions and manage the uplink wireless resources more efficiently on a short-term basis than the wireless network controller.
The enhanced uplink operation requires information such as the uplink signal channel through the downlink enhancement, the allocation of the uplink channel to the wireless transmission/receiving unit, and the transmission of feedback information. The wireless transmission/receiving unit monitors the downlink enhanced uplink signal channel for channel allocation and the reception of transmission feedback information.
What is needed is a method and device for controlling the downlink-enhanced uplink signal channel and enabling it only when needed.
This creation is related to a device used to selectively enable at least one channel to enhance the uplink signal channel reception during the uplink operation. During an enhanced dedicated channel operation, a wireless transmission/reception unit monitors the connection between the wireless transmission/reception unit and the Node B based on the knowledge of the wireless transmission/reception unit in the at least one establishment standard step only when needed. , The established at least one link enhances the uplink signal channel. The wireless transmission/receiving unit coordinates and integrates most of the channel allocation and/or data transmission steps performed by the wireless transmission/receiving unit, and the downlink signal channel reception requirements are consistent with the establishment standard steps. The wireless transmission/reception unit determines whether to enable the reception of at least one specific downlink signal channel according to the integrated downlink signal channel reception requirements.
Consistent with this creation, during the enhanced uplink operation, the wireless transmission/reception unit does not need to continuously cause the downlink to receive the enhanced uplink signal channel. Instead, the wireless transmission/reception unit can be selectively turned on or off (in other words, enabled or disabled), at least one specific downlink enhances the reception of uplink signal channels, thereby reducing the processing needs of the wireless transmission/receiving unit, And reduce the possibility of misinterpretation of the downlink signal.
Hereafter, the term "wireless transmission/reception unit" includes, but is not limited to, a user equipment (UE), a mobile station, a fixed or mobile user unit, a pager, or any device that operates in a wireless environment The form of the device. In the following, the term "B node" includes but is not limited to a base station, a location controller, an access point, or any form of interface device that operates in a wireless environment.
The features of this creation can be combined with an integrated circuit (IC) or configured in a circuit that includes many interconnected components.
Figure 1 is a block diagram of the operation of a wireless communication system 100 consistent with this creation. The system 100 includes a wireless transmission/reception unit (WTRU) 102, at least one Node B 104, and a radio network controller (RNC) 106. The wireless transmission/reception unit 102 includes an enhanced dedicated channel (E-DCH) data buffer 112, a physical reception control entity 114, a receiver 116, a transmitter 118, a processor 120, and a standard database 122.
The transmitter 118 located in the wireless transmission/reception unit 102 transmits an enhanced uplink channel allocation request (in other words, an enhanced uplink channel 108 for enhanced uplink (EU) to the node B 104). A ratio request) to the Node B 104. The enhanced uplink channel allocation request may include scheduling information. The scheduling information may include enhanced dedicated channel data traffic measurement (TVM) information stored in the buffer 112 of the wireless transmission/reception unit 102, and available enhanced uplink transmission power information.
After transmitting the enhanced uplink channel allocation request, the receiver 116 in the wireless transmission/receiving unit 102 monitors a plurality of downlink (DL) enhanced uplinks for channel allocation information through the physical reception control entity 114 Chain signal channel 110<sub>1</sub>、110<sub>2</sub>、…、110<sub>N</sub>. The Node B 104 uses the downlink signal channel 110 to enhance the uplink signal<sub>1-N</sub>One of the on-chain channel allocation information should respond to the on-chain channel allocation request.
The system 100 is configured so that both the uplink signal and the enhanced dedicated channel data are transmitted from the wireless transmission/reception unit 102 to the Node B 104 through the uplink enhanced uplink channel 108. In the slave node B 104, at least the uplink signal channel 110 is enhanced through the downlink<sub>1-N</sub>One is that after receiving scheduling information for channel allocation, the transmitter 118 in the wireless transmission/reception unit 102 transmits enhanced dedicated channel data through the allocated uplink enhanced uplink channel 108. The receiver 116 in the wireless transmission/reception unit 102 then monitors the downlink enhanced uplink signal channel 110 for the expected enhanced dedicated channel data feedback information<sub>1-N</sub>。
In order to respond to the received enhanced dedicated channel data, the Node B 104 uses the downlink enhanced uplink signal channel 110<sub>1-N</sub>, Transmitting the enhanced dedicated channel data feedback information to the wireless transmitting/receiving unit 102. The feedback information includes one of cognition (ACK) information or non-cognition (NACK) information, which is related to the enhanced uplink channel 108 transmitted by the wireless transmission/reception unit 102 through the uplink channel 108 by the node B 104 Decoding of the dedicated channel data succeeded or failed. The Node B 104 can also further transmit channel allocation information in response to enhanced dedicated channel data transmission. Such additional information can also be included in the feedback information, or the uplink signal channel 110 can be enhanced through the downlink.<sub>1-N</sub>Individual transmission.
The role in the wireless transmission/reception unit 102 enhances the state of the uplink step, and can be used to provide the physical reception control entity 114 input of the wireless transmission/reception unit 102. The physical receiving control entity 114 processes communication with a physical layer to selectively enable and disable the downlink to enhance the uplink signal channel 110<sub>1-N</sub>S reception.
Consistent with this creation, the physical receiving control entity 114 of the wireless transmission/receiving unit 102 disables (stops) the downlink enhanced uplink when the steps known by the wireless transmission/receiving unit 102 to enhance the uplink signal are not required. Chain signal channel 110<sub>1-N</sub>S reception. The wireless transmission/reception unit 102 does not need to receive the downlink enhanced uplink signal channel 110<sub>1-N</sub>During the period, the processing requirements and power consumption of the wireless transmission/reception unit 102 can be reduced, and the possibility of misinterpretation of the downlink signal can also be avoided.
Figure 2 is a flow chart of the procedure 200 of the steps of the method for selectively enabling at least the receiving of the downlink enhanced uplink signal channel during the enhanced uplink transmission period consistent with an embodiment of the present creation. In step 202, the wireless network controller 106 configures the wireless transmission/reception unit 102 to perform enhanced dedicated channel operation, thereby establishing the uplink between the wireless transmission/reception unit 102 and the Node B 104 Enhanced uplink channel 108 and the downlink enhanced uplink signal channel 110<sub>1-N</sub>. The wireless transmitting/receiving unit 102 does not need to be in the wireless transmitting/receiving unit 102, and immediately enables its downlink enhanced uplink signal channel 110 after configuration<sub>1-N</sub>S reception. Therefore, the physical reception control entity 114 of the wireless transmission/reception unit 102 disables the downlink enhanced uplink signal channel 110<sub>1-N</sub>S reception.
Still referring to FIG. 2, after configuring the wireless transmission/reception unit 102 for enhanced dedicated channel operation in step 202, the wireless transmission/reception unit 102 monitors its enhanced dedicated channel data buffer 112 (step 204). If, in step 206, the wireless transmission/reception unit 102 determines that there is no enhanced dedicated channel data in the buffer 112, the wireless transmission/reception unit 102 continues to monitor the buffer 112, and in the next step 204 Chain enhanced on-chain signal channel 110<sub>1-N</sub>Accepted, and still remain disabled. If, in step 206, the wireless transmission/receiving unit 102 determines that there is enhanced dedicated channel data (in other words, a row) waiting to be transmitted through the uplink enhanced uplink channel 108 in the buffer 112, the wireless transmission/reception unit 102 Through the uplink enhanced uplink channel 108, an enhanced uplink channel allocation request with or without enhanced dedicated channel data is transmitted to the node B 104, and at least the downlink enhanced uplink signal channel 110 is enabled<sub>1-N</sub>The reception (step 208). After a predetermined or calculated delay, the wireless transmission/reception unit 102 can selectively enable the downlink to enhance the uplink signal channel 110<sub>1-N</sub>S reception. The enhanced uplink channel allocation request may include scheduling information such as data traffic measurement information and available enhanced uplink transmission power information.
To operate the enhanced dedicated channel, the Node B needs to schedule and respond to an enhanced uplink channel allocation request transmitted by the wireless transmission/reception unit 102, and notify the wireless transmission/reception unit 102 of the wireless resource allocation. According to the established notification step, the wireless transmitting/receiving unit 102 keeps track of at least the down-link enhanced uplink signal channel 110 according to the enhanced uplink channel allocation request transmitted by the wireless transmitting/receiving unit 102.<sub>1-N</sub>, When to receive the required or expected enhanced dedicated channel data transmission schedule information including enhanced uplink channel allocation from the Node B (step 210).
In step 212, the wireless transmission/reception unit 102 enhances the uplink signal channel 110 through the downlink.<sub>1-N</sub>, Receiving the required or expected scheduling information from the Node B 104, and then if there is no entity request, the physical receiving control entity 114 disables the downlink enhanced uplink signal channel 110<sub>1-N</sub>S reception. Optionally, in step 214, the wireless transmission/reception unit 102 schedules the downlink enhanced uplink signal channel 110 according to the downlink enhanced uplink signal channel scheduling information if configured to receive periodically<sub>1-N</sub>S reception. The downlink enhanced uplink signal channel 110<sub>1-N</sub>The reception of is related to which step of enhancing the uplink signal in the wireless transmission/reception unit 102 is caused by being effective.
Figure 3 is consistent with another embodiment of this creation. When the wireless transmitting/receiving unit 102 transmits enhanced dedicated channel data and expects to receive feedback information, it includes selectively enabling at least one-link enhanced uplink signal channel 110<sub>1-N</sub>A flowchart of the procedure 300 of the steps of the receiving method. In step 302, the wireless network controller 106 configures the wireless transmission/reception unit 102 to perform enhanced dedicated channel operations, thereby establishing the uplink between the wireless transmission/reception unit 102 and the Node B 104 Enhanced uplink channel 108 and the downlink enhanced uplink signal channel 110<sub>1-N</sub>. The wireless transmitting/receiving unit 102 does not need to be in the wireless transmitting/receiving unit 102, and immediately enables its downlink enhanced uplink signal channel 110 after configuration<sub>1-N</sub>S reception. Therefore, the physical reception control entity 114 of the wireless transmission/reception unit 102 disables the downlink enhanced uplink signal channel 110<sub>1-N</sub>S reception.
Still referring to FIG. 3, after configuring the wireless transmission/reception unit 102 to implement enhanced dedicated channel operation in step 302, the wireless transmission/reception unit 102 monitors its enhanced dedicated channel data buffer 112 (step 304). If, in step 206, the wireless transmission/reception unit 102 determines that there is no enhanced dedicated channel data in the buffer 112, the wireless transmission/reception unit 102 continues to monitor the buffer 112, and in the next step 304 Chain enhanced on-chain signal channel 110<sub>1-N</sub>Accepted, and still remain disabled.
Steps 308, 310, 312, and 314 of the procedure 300 can be implemented in parallel in the wireless transmission/reception unit 102 for a plurality of hybrid automatic repeat request (H-ARQ) processing operations. If, in step 306, the wireless transmission/reception unit 102 determines that there is enhanced dedicated channel data (in other words, ranks) waiting to be transmitted through the uplink enhanced uplink channel 108, for each hybrid automatic retransmission request processing, the wireless transmission The /receiving unit 102 transmits an enhanced uplink channel allocation request with or without enhanced dedicated channel data to the node B 104 through the uplink enhanced uplink channel 108, and enables the downlink enhanced uplink signal channel 110<sub>1-N</sub>Is received (step 308). After a predetermined or calculated delay, the wireless transmission/reception unit 102 can selectively enable the downlink to enhance the uplink signal channel 110<sub>1-N</sub>S reception.
According to the established notification step, the wireless transmission/reception unit 102 keeps track of when it receives the required or expected feedback information from the Node B 104 for each hybrid automatic retransmission request processing (step 310). In step 312, the wireless transmission/reception unit 102 receives feedback information from the Node B 104, and if it is not required by any entity, disables the downlink enhanced uplink signal channel 110<sub>1-N</sub>S reception. Optionally, in step 314, the wireless transmission/reception unit 102 schedules the downlink enhanced uplink signal channel 110 according to the feedback information that is periodically received if configured<sub>1-N</sub>S reception. Specific downlink enhanced uplink signal channel 110<sub>1-N</sub>The reception of is related to which step of enhancing the uplink signal in the wireless transmission/reception unit 102 is caused by being effective.

Downlink enhanced uplink signal channel 110<sub>1-N</sub>In order to enhance the dedicated channel transmission, it is used to provide feedback information from the Node B 104 to the wireless transmission/reception unit 102. Because the feedback transmitted to the wireless transmission/receiving unit reflects a specific action of the wireless transmission/receiving unit, the feedback information reception time of the wireless transmission/receiving unit can be correctly determined by the wireless transmission/receiving unit. The node B 104 enhances the uplink signal channel 110 through the downlink<sub>1-N</sub>The transmitted feedback information can be composed of mixed automatic retransmission request approval and/or uplink channel allocation information. Examples of the wireless transmission/receiving unit receiving feedback channels can be like the hybrid automatic retransmission request information channels (HICHs) and relative consent channels (RGCHs) or absolute consent channels (AGCH) in the third-generation mobile communication cooperation project.
