Method for base station to process channel quality indicators reported by terminal

Abstract

The invention provides a method for a base station to process CQIs (channel quality indicators) reported by a terminal. The method includes the steps: A, enabling the base station to receive the CQIs reported by the terminal and make statistics on receiving transmission performance of the CQIs; B, enabling a base station to judge whether CQI receiving times reach a time threshold or not, continuing to execute a step C if yes, and otherwise, returning to the step A; C, enabling the base station to judge whether the receiving transmission performance reaches a performance threshold or not, continuing to execute a step D if yes, and otherwise, executing a step E; D, enabling the base station to decrease processing frequency of the CQIs periodically reported by the corresponding terminal, and returning to the step A; and E, enabling the base station to increase the processing frequency of the CQIs periodically reported by the corresponding terminal, and returning to the step A.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a method for a base station to process a channel quality indicator reported by a terminal. Background technique [0002] In the closed-loop transmission mode of the LTE system, the base station can configure the terminal to periodically report channel quality indicator (CQI) information for the base station to perform transmission mode configuration and air interface resource scheduling. [0003] figure 1 It is a schematic diagram of a base station in the prior art processing the CQI reported by the terminal. The base station (eNB) sends a configuration message to the terminal (UE) at the starting point of the CQI report, requesting the UE to report the CQI periodically. After that, the UE reports the CQI to the eNB in ​​the agreed subframe, and the base station detects whether the CQI reported by the UE is received in the corresponding subframe, and if so, ...

AI Technical Summary

Problems solved by technology

[0004] In an environment with relatively stable transmission quality, if the base station does not change the transmission mode and air interface resource scheduling, the difference in the CQI information reported by the terminal is very small. In this environment, if the base station receives and processes all the CQI reported by the terminal, the obtained The amount of information is very small, and a large amount of calculation is wasted, which reduces the effectiveness of the processing; if the base station reconfigures the CQI reporting period of the terminal, it needs to increase the air interface signaling interaction process and increase the complexity of base station resource configuration. It also increases the complexity of base station and terminal processing
