Problems solved by technology

In the current channel quality indication information reporting method, the direct adjustment objects associated with the channel quality indication are all channel quality indication (CQI, Channel Quality Indication) calculation values; according to the provisions of the agreement, the CQI calculation value is generally a non-negative integer, This determines that the minimum granularity of CQI calculation value adjustment is 1, therefore, none of the existing technical solutions can achieve fine adjustment of channel quality indication information
This will cause the transmission mode selected by the network side to either fail to meet the communication quality of the UE, or cause a reduction in wireless data transmission efficiency

Abstract

An embodiment of the invention discloses a channel quality indication information adjusting method and device and a mobile terminal. The method comprises obtaining a first quality parameter of the channel, and determining whether the first quality parameter is larger than or equal to a first set threshold; subtracting a first adjusting step length from the adjusting amount of a second parameter corresponding to the first quality parameter when the first quality parameter is larger than or equal to the first set threshold; obtaining a second quality parameter of the channel, and accumulating the second quality parameter with the adjusting amount to be used as the adjusted second quality parameter; determining a third quality parameter according to the adjusted second quality parameter and reporting the third quality parameter.

Description

technical field [0001] The invention relates to channel quality indication information adjustment technology, in particular to a channel quality indication information adjustment method and device, and a mobile terminal. Background technique [0002] When performing wireless communication, user equipment (UE, User Equipment) needs to perform channel measurement, and report channel quality indication information to the network side according to the channel measurement results, so that the network side can select an appropriate encoding method for the UE to ensure that the UE can correctly receive wireless communication. Data, the communication quality can be guaranteed regardless of the communication conditions. In the current channel quality indication information reporting method, the direct adjustment objects associated with the channel quality indication are all channel quality indication (CQI, Channel Quality Indication) calculation values; according to the provisions of...
