Claim of US Patent No. 10,973,035

1. A method, performed by an access point, for scheduling transmission to a plurality of wireless communication devices, the method comprising:selecting respective modulation and coding schemes (MCS) for the wireless communication devices, wherein each selected MCS is associated with a corresponding power back-off;
sorting the wireless communication devices into two or more groups, wherein each group has a maximum size and wherein sorting comprises:
letting first wireless communication devices having the same first MCS and the same first power back-off belong to the same group, and
if the maximum size is not reached for the group, letting a second wireless communication device having a second MCS and a second power back-off belong to the same group, as the first wireless communication devices, if a grouping criterion is met,
wherein the grouping criterion is based on at least the first power back-off; and
scheduling each of the two or more groups of wireless communication devices on different transmission resources than used to schedule others of the two or more groups.
