Problems solved by technology

[0012] The base station in the prior art does not update the "type A proportion", only the radio network controller can reconfigure the "type A proportion", but when the radio network controller reconfigures the "type A proportion", It is impossible to know the channel status that the UE is using, so the reconfiguration performed by the radio network controller does not necessarily conform to the current actual situation of the UE, resulting in the UE being unable to report the CQI reasonably according to the actual situation, thus reducing the system performance

Embodiment Construction

[0031] Embodiments of the present invention provide a channel quality indicator reporting control method, base station and user equipment, which are used to dynamically adjust the proportion of type A, so that UE can report CQI reasonably according to actual conditions, thereby improving system performance.

[0032] see figure 1 , the CQI reporting control method in an embodiment of the present invention may include:

[0033] 101. The base station judges whether the buffered data volume of the UE meets the adjustment condition, and if so, executes step 102;

[0034] In this embodiment, the base station can determine whether the cached data volume of a certain UE meets a preset adjustment condition from a cached queue stored locally. The cached queue is preset in the base station, and each UE corresponds to a cached queue.

[0035] 102. Adjust the type A ratio, and send the adjusted type A ratio to the UE, and then the UE reports the CQI according to the adjusted type A ratio....

Abstract

The embodiment of the invention discloses a method for controlling the reporting of a channel quality indicator (CQI), a base station and user equipment, which are used for improving the performance of a system. The method of the embodiment of the invention comprises the following steps of: determining whether the cached data quantity of the user equipment (UE) meets the adjustment condition or not; if so, adjusting the proportion of type A; transmitting the adjusted proportion of type A to the UE; and reporting the CQI by the UE according to the adjusted proportion of type A. The embodiment of the invention also provides the base station and the user equipment. The embodiment of the invention can effectively improve the performance of the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a channel quality indicator reporting control method, a base station and user equipment. Background technique [0002] After the introduction of MIMO (Multi Input Multi Output) technology in the R7 version of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), it is stipulated that the user equipment (UE, User Equipment) should report the following two types of channel quality Indication (CQI, Channel Quality Indication): [0003] 1. Type A (Type A) CQI: [0004] If the UE feels that it is suitable to use dual-stream transmission, the Type A CQI is the dual-stream CQI value (CQI1 and CQI2); [0005] If the UE feels that it is suitable to use single-stream transmission, the Type A CQI is a single-stream CQI value (CQIs); [0006] The process for the specific UE to determine which transmission mode is suitable can be determined by each terminal ma...
