Abstract:
1. A method of adjusting a modulation and coding scheme, the method comprising: selecting a modulation and coding scheme for a plurality of terminals by a base station; broadcasting a modulation and coding scheme identifier to the plurality of terminals, the modulation and coding scheme identifier configured to identify the selected modulation and coding scheme such that each of the plurality of terminals transmits a transmission to the base station based at least in part on the selected modulation and coding scheme; and receiving a second modulation and coding scheme identifier from one of the plurality of terminals, the second modulation and coding scheme identifier configured to identify a modulation and coding scheme adjusted at one of the plurality of terminals, wherein the adjusted modulation and coding scheme is determined by the one of the plurality of terminals performing operations comprising: calculating a success rate for the modulation and coding scheme; determining whether the success rate is within a target success rate range; and in response to the success rate being outside and less than the target success rate range, determining whether to decrease the modulation and coding scheme; or in response to the success rate being outside and greater than the target success rate range, determining whether to increase the first modulation and coding scheme.
