Abstract
The invention relates to a method and apparatus for determining whether two user equipments (UEs) in a wireless network can be co-scheduled by an uplink scheduler of a base station. The method includes: the determination of a steering vector for each of a plurality of user equipments to be considered; and, for each pair of the user equipments, the determination of a corresponding orthogonality factor based on the steering vectors of the user equipments comprising the pair. A pair of user equipments may be selected for co-scheduling based on the orthogonality factors. For example, a pair of user equipments may be co-scheduled if its orthogonality factor is below a threshold. As another example, a pair of user equipments that has the lowest of the orthogonality factors may be co-scheduled.
