Problems solved by technology

When there are many UEs, if a smaller code rate is used, one UE needs to use more resources to transmit data, and within one scheduling time, the number of UEs that can be scheduled is small, resulting in low utilization of spectrum resources

Abstract

The invention provides an information reporting method and a communication device, and the method comprises the steps that first equipment receives first indication information from second equipment,and the first indication information is used for indicating at least two BLERs; the first equipment reports CQI (Channel Quality Indicator) respectively corresponding to the at least two BLERs to thesecond equipment through at least two physical uplink control channel resources, wherein the at least two physical uplink control channel resources respectively correspond to the at least two BLERs. The first equipment can reasonably use the physical uplink control channel resources and report the CQI corresponding to the at least two BLERs to the second equipment, thereby reasonably allocating the size of the downlink transmission data block and ensuring that the first equipment obtains the optimal downlink performance.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and a communication device for reporting a channel quality indicator in a wireless communication system. Background technique [0002] Channel quality indication (channel quality indication, CQI) is the measurement standard of the communication quality of the wireless channel. The CQI is measured by the user equipment (user equipment, UE). The base station determines the transmission data block size, coding method, and modulation according to the CQI reported by the UE. way etc. [0003] In the long term evolution (LET) protocol, the CQI measurement method is not clearly defined, only the selection principle of the CQI is defined, that is, to ensure the decoding error rate of the physical downlink shared channel (PDSCH). The block error ratio (BLER) is less than 10% of the used CQI. Three major scenarios in the 5th Generation mobile communi...
