Publication number: 20180091257Abstract: A method for multi-user multiple-input multiple-output (MU-MIMO) communications between a communications device and a client station (STA). The communications device may initiate MU-MIMO transmissions to the STA according to a first modulation and coding scheme (MCS) and a first transmission power. The device may monitor packet error rates (PERs) associated with the MU-MIMO transmissions to the STA and select a second MCS to be used for subsequent MU-MIMO transmissions to the STA based, at least in part, on the PERs and the first transmission power. The device may determine a target transmission power associated with the first MCS and compare the target transmission power with the first transmission power. The selection of the second MCS may be based, at least in part, on the comparison. The device may record PERs associated with the MU-MIMO transmissions, in a PER table, in relation to the first transmission power.Type: ApplicationFiled: September 27, 2016Publication date: March 29, 2018Inventors: Gregory Steele, Ahmed Ragab Elsherif
