Problems solved by technology

First, both solutions are equivalent to configuring only one available SPS configuration for the UE, so that even if the UE is not scheduled this time, the PUCCH resource position is still reserved, causing unnecessary waste; second, Solution 1 does not use the flexible scheduling function of the PDCCH field. Although Solution 2 uses the flexible scheduling function of the PDCCH field, the actual effect is the same as that of Solution 1, and no obvious benefits are introduced.

Abstract

The present invention relates to an SPS business PUCCH channel dynamic distribution method and device. The method comprises: the same PUCCH channel resource set is configured for a plurality of SPS business terminals, and the resource index value of each PUCCH channel resource in the configured resource set is sent to each SPS business terminal; PUCCH subframes corresponding to the dispatched time of the SPS business terminal having the arrival of the downlink SPS business according to the sequential relationship are determined; and resource blocks, of the PUCCH channel resource set configured by the SPS business terminal, without being occupied in the determined PUCCH subframes are searched, and the position identification of the PUCCH channel resource including the searched resource blocks is sent to the SPS business terminal. Therefore, the resource blocks of the same PUCCH channel located at different subframes can be distributed to different SPS business terminals for usage with no need for fixedly distributing one PUCCH channel for each SPS business terminal so as to improve the resource utilization rate of the PUCCH channel.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a PUCCH channel dynamic allocation method and device for SPS services. Background technique [0002] In an LTE (Long Term Evolution, long-term evolution system) system, a PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) mainly carries uplink control information (Uplink Control Information, UCI) fed back to a base station. Uplink control information includes: SR (Schedule Request, scheduling request), ACK / NACK (Acknowledgment, positive acknowledgment / Negative Acknowledgment, negative acknowledgment) and CQI / PMI (Channel Quality Indicator, downlink channel quality indicator / Precoding Matrix Indicator, precoding matrix Indication) and RI (Rank Indicator, level indication), corresponding to the Format1, Format1A / 1B and Format2 / 2A / 2B formats of the PUCCH. details as follows: [0003] Format1: used for UE (User Equipment, user equipment)...
