Embodiment Construction

[0075] Embodiments of the present invention provide a method for allocating uplink control channel resources of 2-antenna ports and a base station. According to the downlink semi-persistent scheduling reserved for 2-antenna ports by the system, the continuous frequency Domain resources, determine at least one set of resource lists, and then allocate two resource lists in a set of resource lists for the two antenna ports of the UE, realizing the 2-antenna port PUCCH for ACK / NACK feedback of downlink semi-persistent scheduling resource allocation.

[0076] like figure 1 As shown, the 2-antenna port uplink control channel resource allocation method provided by the embodiment of the present invention includes:

[0077] Step S101, according to the continuous frequency domain resources of the physical uplink control channel PUCCH reserved for the downlink semi-persistent scheduling acknowledgment ACK / non-acknowledgment NACK feedback of the 2-antenna port, at least one set of resour...

Abstract

The invention discloses a 2-antenna port uplink control channel resource allocation method and a base station, relating to communication technology, according to the physical uplink control channel PUCCH reserved for 2-antenna port downlink semi-persistent scheduling confirmation ACK / non-acknowledgment NACK feedback For continuous frequency domain resources, at least one set of resource lists is determined, and then two resource lists in a set of resource lists are assigned to the two antenna ports of the UE, realizing 2-way ACK / NACK feedback for downlink semi-persistent scheduling Antenna port PUCCH resource configuration.

Description

technical field [0001] The present invention relates to communication technology, in particular to a 2-antenna port uplink control channel resource allocation method and a base station. Background technique [0002] The LTE-A (Long Term Evolution Advanced) system uses the PUCCH (Physical Uplink Control Channel) to transmit synchronized UCI (Uplink Control Information, uplink control information). The uplink control information transmitted on the PUCCH mainly includes SRI ( Scheduling Request Indicator, scheduling request indicator), downlink ACK / NACK feedback, and periodic CQI (Channel Quality Indicator, channel quality indicator) / PMI (Precoding Matrix Indicator, precoding matrix indicator) / RI (Rank Information, rank information) report information. According to different information carried on the PUCCH, multiple PUCCH formats such as PUCCH format1 / 1a / 1b, PUCCH format2 / 2a / 2b, and PUCCH format3 are defined. The resource used to transmit PUCCH format1 / 1a / 1b is defined as PUC...
