Embodiment 1

[0036] Such as image 3 As shown, the PUCCH resource configuration method in the embodiment of the present invention is to set the same PUCCH format channel starting point and different dynamic acknowledgment / negative response resource mapping start offsets for multiple downlink component carriers; wherein the multiple The PUCCH resource of the downlink component carrier corresponds to the same uplink component carrier. The starting point of setting the same PUCCH format channel is specifically setting the same second parameter and third parameter, wherein the second parameter indicates the maximum number of resource blocks used to transmit the PUCCH format 2 / 2a / 2b channel; The number of cyclic shifts of the banner zero autocorrelation sequence allocated to the PUCCH format 1 / 1a / 1b channel on the resource block. The setting of different dynamic acknowledgment / negative response resource mapping start offsets is specifically setting different fourth parameters, wherein the four...

Embodiment 2

[0063] In the above embodiments, except for the dynamic ACK / NACK mapping resources, the rest of the PUCCH resources are fully shared among all component carriers. And it is also possible to set a different second parameter N RB (2) and / or third parameter N CS (1) , so that the PUCCH resources other than the dynamic ACK / NACK mapping resources are partially shared, and the fourth parameter N PUCCH，i (1) to control whether the dynamic ACK / NACK mapping resources between multiple downlink component carriers overlap each other.

[0064] The method for configuring PUCCH resources in Embodiment 2 of the present invention is to set a different PUCCH format 1 / 1a / 1b channel starting point for at least one of the multiple downlink component carriers, and set a different starting point for the downlink component carrier among the multiple downlink component carriers. Different dynamic ACK / NACK resource mapping start offset settings; wherein the multiple downlink component carriers acq...

Abstract

The invention relates to a configuration method of PUCCH (Physical Uplink Control Channel) resources. The method comprises the following steps of: arranging the same PUCCH format channel starting point for a plurality of downlink component carriers, and arranging different dynamic Acknowledgement / Negative-Acknowledgement (ACK / NACK) resource mapping start offsets, wherein the PUCCH resources of the downlink component carriers correspond to the same uplink component carrier. In the invention, the flexible PUCCH resource sharing is realized by arranging the same PUCCH format channel starting point for the downlink component carriers, and the overhead compaction of dynamic ACK / NACK mapping resources is realized by arranging different dynamic ACK / NACK resource mapping start offsets.

Description

technical field [0001] The embodiment of the present invention relates to the field of mobile communication, in particular, a method for configuring and sending PUCCH resources of a physical layer uplink control channel and a device thereof. Background technique [0002] In a wireless communication system, in order to assist the communication between the base station and the user equipment, the user equipment needs to feed back uplink control information to the base station. Uplink control information includes: Acknowledgment / Negative-Acknowledgment (ACK / NACK), which is used for user equipment to indicate to the base station whether the data reception is correct; rank indicator (Rank Indicator, RI), channel quality indicator (Channel Quality Indicator , CQI) and precoding matrix indicator (Precoding Matrix Indicator, PMI), used for user equipment to indicate the measured downlink channel quality conditions to the base station; scheduling request indicator (Scheduling Reques...
