Abstract

The invention discloses a method for adjusting a channel quality indicator (CQI) and equipment. According to the method, a CQI during primary transmission of user data is adjusted according to the magnitude relationship between current retransmission number of times and preset retransmission number of times of the user date, and the user date is retransmitted by the use of the adjusted CQI. Thus, HARQ gain and the preset retransmission number of times corresponding to different business types of users are combined, self-adapting adjustment of the retransmission CQI is realized, and system performance is improved.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a method and equipment for adjusting channel quality indication. Background technique [0002] In an existing wireless communication system, data transmission uses a hybrid automatic requestor (Hybrid Automatic Requestor, HARQ) technology, and HARQ gains are obtained through retransmission combining. Judging from the current application situation, most of the scheduled Transport Block Size (Transport Block Size, TBS) can be received by users after one retransmission. Therefore, the gain of HARQ combination is relatively large, and it is necessary to consider how to combine Use this part of the gain reasonably. In addition, different service types have different requirements for delay quality of service (QoS) and the number of retransmissions, which need to be considered together. [0003] At present, the simplest retransmission resource allocation method is to directly use...
