Problems solved by technology

Reporting the CQI value too frequently will lead to an increase in the load of the uplink channel, and reporting too little will lead to inaccurate UE channel condition indication obtained by the network side
There is a time delay due to the above-mentioned measurement and periodic reporting. The above-mentioned delay may cause the CQI value of the HSDPA scheduling reference on the network side to be inconsistent with the current channel condition of the UE, thereby reducing the user data transmission rate and the service quality (Quality of Service, Qos ) and system air interface capacity

Abstract

The embodiment of the invention discloses a method and a device for processing channel quality. The method for processing the channel quality comprises the following steps of: receiving a channel quality indication (CQI) value sent by user equipment; compensating the received CQI value by using channel parameters related with the channel quality of the user equipment; and converging the signal-to-noise ratio of a channel of the user equipment to be smaller than a target value. The technical scheme provided by the embodiment of the invention is favorable for improving the transmission rate of user data, the quality of service (QoS) and the null capacity of a system on the premise of reducing the load of an uplink channel.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a channel quality processing method and device. Background technique [0002] Channel Quality (Channel Quality) evaluation process has a wide range of applications in the field of communication, with the High Speed ​​Data Packet Access (HSDPA) introduced from R5 by the Third Generation Partnership Project (Third Generation Partnership Project, 3GPP) ) as an example. In HSDPA, the network side transmits data for users through the high-speed downlink physical channel HS-PDSCH, and uses the high-speed shared control channel (High Speed ​​Sharing Control Channel, HS-SCCH) as the high-speed physical data sharing channel (High Speed ​​Physical Data Sharing Channel, HS -PDSCH) control channel, indicating HS-PDSCH-related control information. The UE side uses the uplink high-speed dedicated physical control channel (High Speed ​​Dedicated Physical Control Channel, HS-DPC...
