Abstract

The embodiment of the invention provides a method and a device for PUSCH (Physical Uplink Shared Channel) scheduling of a terminal, relating to a network communication technology. The method comprises the steps of: according to the RIP (Routing Information Protocol) of an upstream subframe of the PUSCH of the terminal and the RIP of an upstream subframe of an SRS (Sounding Reference Signal), correcting a CQI (Channel Quality Indicator) of an upstream subframe of the SRS to obtain the CQI of the upstream subframe of the PUSCH, determining the grade of the initial MCS (Modulation and Coding Scheme) of the upstream subframe of the PUSCH according to the CQI of the upstream subframe of the PUSCH, and carrying out next scheduling on the terminal according to the grade of the MCS of the upstream subframe of the PUSCH. According to the technical scheme, by means of taking the influence of different interference levels of different upstream subframes to the grade of the MCS of the scheduled PUSCH into consideration and jointly determining the grade of the initial MCS according to the CQI of the upstream subframe of the SRS and the actual condition of the upstream subframe of the PUSCH, the signal transmission ratio is improved, and the error rate is reduced.

Description

technical field

[0001] The present invention relates to network communication technology, in particular to a terminal PUSCH scheduling method and device. Background technique

[0002] In the Time Division Long Term Evolution (TDD LTE) system of mobile communication, there are many forms of interference, including full-time full-band interference, full-time part-frequency band interference, and the most common crossover slot interference. For example, when networking, the signal transmission environment of some base stations has a water surface, which will cause the signal transmission to be far away and interfere with the signal reception of the uplink subframe of other base stations; the GPS direction of some base stations is incorrect, and the downlink signal sent will interfere with other base stations. The signal reception of the uplink subframe of the base station; there are also some base stations with the same frequency network, but when the uplink and downlink subfr...
