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

Embodiment Construction

[0019] The flow of the base station processing the CQI reported by the terminal proposed by the embodiment of the present invention is as follows: figure 2 shown, including the following steps:

[0020] Step 201: the base station receives the CQI reported by the terminal, and collects statistics on the reception and transmission performance of the CQI (eg, block error rate (BLER)).

[0021] Step 202: The base station judges whether the number of times of receiving CQI reaches the pre-configured number threshold, if yes, continue to execute step 203, otherwise return to step 201.

[0022] Step 203: The base station judges whether the receiving and transmission performance reaches a pre-configured performance threshold, and if so, executes step 204, otherwise executes step 205.

[0023] Step 204: The base station reduces the processing frequency of periodically reporting the CQI to the corresponding terminal. And return to step 201, and perform statistics on the reception and...

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 technical field of wireless communication, in particular to a method for a base station to process a channel quality indication 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 configure transmission modes and schedule air interface resources. [0003] figure 1 It is a schematic diagram of processing the CQI reported by the terminal by the base station in the prior art. The base station (eNB) sends a configuration message to the terminal (UE) at the start point of the CQI report, requiring 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, receive...
