Scheduling of wireless communication devices

Abstract:

Disclosed is a method for an access point of scheduling a plurality of wireless communication devices for transmission. The method comprises selecting (210) a respective modulation and coding scheme--MCS--for each of the plurality of wireless communication devices, wherein each of the respective MCS:s is associated with a respective power back-off, sorting (220) the plurality of wireless communication devices into two or more groups, wherein each group has a maximum size, and scheduling (230) each of the two or more groups of wireless communication devices on different respective transmission resources. The sorting comprises letting first wireless communication devices having the same first respective MCS and the same first respective power back-off belong to the same group. The sorting also comprises (if the maximum size is not reached for the group) letting a second wireless communication device having a second respective MCS and a second respective power back-off belong to the group if a grouping criterion is met. The grouping criterion is based on at least the first respective power back-off. Corresponding arrangement, access point and computer program product are also disclosed.
