Example Embodiment

[0032] Example 1

[0033] like image 3 As shown, the method for configuring PUCCH resources in the first embodiment of the present invention is to set the same PUCCH format channel starting point for multiple downlink component carriers, and different dynamic ACK / NAK resource mapping starting offsets; The PUCCH resources of the downlink component carrier correspond to the same uplink component carrier. Wherein, the setting of the same PUCCH format channel starting point is specifically setting the same second parameter and third parameter, wherein the second parameter represents 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 on the resource block allocated to the PUCCH format 1 / 1a / 1b channel. The setting of different dynamic ACK / NA response resource mapping start offsets is specifically to set a different fourth parameter, where the fourth parameter represents t...

Example Embodiment

[0059] Embodiment 2

[0060] In the above embodiment, except for the dynamic ACK / NACK mapping resources, the rest of the PUCCH resources are completely shared among all component carriers. And also by setting different second parameters and / or third parameter The PUCCH resources other than the dynamic ACK / NACK mapping resources are partially shared, and the fourth parameter can also be passed to control whether the dynamic ACK / NACK mapping resources among multiple downlink component carriers overlap each other.

[0061] The method for configuring PUCCH resources according to the second embodiment of the present invention is to set different PUCCH format 1 / 1a / 1b channel starting points for at least one downlink component carrier in the multiple downlink component carriers, and set different channel starting points for the downlink component carriers in the multiple downlink component carriers. Different dynamic ACK / NACK resource mapping start offset settings; wherein the ...

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 by the 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 (PrecodingMatrix Indicator, PMI), used for user equipment to indicate the measured downlink channel quality conditions to the base station; scheduling request indicator (Scheduling Reque...
