Adaptive modulation and coding set system of wireless communication networks

摘要

Adaptive modulation and coding adjustment system in wireless communication networks.In a method of adjusting a modulation and docificau00e7u00e3o system level (MCS) for transmission over a communication channel between a base station and a mobile terminal.In the base station: a target value of a metric of error is defined; the measure of error is measured; a MCS displacement based on a degree of deviation of the measurement error metric of the target value is determined; an indication of a quality measurement of the channel for the communication channel is Received from the mobile terminal; a preset level corresponds to MCS indication of measuring the quality of CAnal is determined using a fixed mapping between a set of u00edveis quality of channel and a corresponding set of levels of MCS, MCS level set is determined by adding the MCS displacement to the MCS level pre adjusted, and the adjusted level MCS is attributed to t.
