Base station for allocating channel state reports and channel state report allocation method

Abstract

The invention discloses a base station for allocating channel state reports and a channel state report allocation method. The base station comprises a memory, a communication module and an arithmeticprocessor. The arithmetic processor drives the communication module to respectively send RRC configuration messages including periodic channel state information return parameters and discontinuous reception parameters to a plurality of user equipments. The periodic channel state information return parameter comprises a return period, return time displacement and PUCCH resource information. The RRCconfiguration messages comprise the same return period, return time displacement and PUCCH resource information. When the arithmetic processor predicts that a plurality of conflicting user devices inthe user devices execute channel state information return at the same time, the arithmetic processor determines that one of the conflicting user devices executes channel state information return andsends a sleep instruction to other conflicting user devices except the conflicting user device capable of executing channel state information return.

Description

technical field [0001] The invention relates to a base station capable of allocating channel state reports and a method for allocating channel state reports. Background technique [0002] In the current Long Term Evolution (LTE) network, in order to improve spectrum utilization efficiency and provide better service quality for the UE, the network often requires the UE to perform wireless channel measurement and report back. If the network side needs the user equipment (UE) to report the channel state information (CSI) periodically, it usually configures the UE-specific Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) resources for periodic CSI reporting. However, when the number of UEs or the number of antennas increases, the overall system bandwidth occupied by the PUCCH will increase accordingly, resulting in the reduction of the available uplink bandwidth of the UE, that is, the bandwidth of the Physical Uplink Shared Channel (PUSCH) decreases. ...
