Abstract

The present invention provides a wireless communication system uplink multi -child resource allocation method, device and user equipment. This method includes: user equipment UE sends upward resources to the base station through a wireless frame.The first feedback information, the second feedback information of the PUCCH2 bearer, the context used to estimate the PUCCH1 and PUCCH2, the frequency of the estimated PUSCH 2. and the data information carried by the PUSCH; where the upward resources in the wireless frame areDistributed according to the preset resource allocation strategy.This method can effectively improve the upward spectrum efficiency of the system, and through feedback to control the design of the channel PUCCH, it can support the distribution of dynamic spectrum resources of the wireless communication system.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and user equipment for uplink multi-subband resource allocation in a wireless communication system. Background technique [0002] A wireless communication system occupies a discontinuous spectrum bandwidth, and its schematic diagram is as follows figure 1 shown. Each physical channel with a frequency domain of 25kHz bandwidth is defined as a frequency point, up to frequency points. Each frequency point adopts Orthogonal Frequency Division Multiplexing (OFDM) technology. All discontinuous frequency points are aggregated together, and the system performs unified scheduling and assigns them to users, which constitutes this communication system with carrier aggregation characteristics. . [0003] In this wireless communication system, a wireless frame corresponding to each frequency point has a length of 25ms and contains 45 OFDM symbols...
