Abstract

The invention provides a link self-adaptive adjustment method, a base station and core network side equipment. The method is applied to a base station and comprises the steps of obtaining input data;wherein the input data comprises current carrier channel intensity distribution information, channel error information, channel quality indicator (CQI), a user multiple-input multiple-output (MIMO) transmission mode and the current number of MIMO service users of the base station of the target user terminal (UE); obtaining a target output data set output by the link adaptive decision model according to the input data and the link adaptive decision model; determining a target modulation and coding strategy MCS according to the target output data set; and performing adaptive adjustment on a linkbetween the base station and the target UE according to the target MCS. Compared with the prior art, the embodiment of the invention can better ensure the link self-adaptive adjustment effect.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a link self-adaptive adjustment method, base station and core network side equipment. Background technique [0002] Due to the effects of propagation loss, fast fading, slow fading, and interference changes, wireless channels have time-varying characteristics. In order to maximize system performance, adaptive modulation and coding (AMC) is often used as a link adaptation technology to adapt to the impact of wireless channel changes. [0003] Specifically, when AMC is adopted, a user terminal (User Equipment, UE) first measures downlink channel quality by detecting a downlink common reference signal, and calculates a corresponding signal to interference ratio (Signal to Interference and Noise, SINR). Next, the UE maps the calculated SINR to a specific channel quality indicator (Channel quality indicator, CQI) through a certain method, and feeds back the map...
