ABSTRACT:
Machine-readable media, methods, apparatus and system for allocating power in a MU-MIMO communicating system are described. In some embodiments, an apparatus of a base station in the MU-MIMO communication system may comprise: a power calculating logic to calculate a power for each user of a plurality of users communicating with the base station in the MU-MIMO system, based upon an average power and a power increment. The power calculating logic may further comprise an average power logic to calculate the average power among the plurality of users based upon a total power for the base station to communicate with the plurality of users, and a power increment logic to determine the power increment for the each user based upon at least one of a fairness algorithm and a throughput algorithm, and wherein different users of the plurality of users having different long-term signal to interference plus noise ratios (SINRs) are calculated with different powers. The apparatus may further comprise a power allocating logic to allocate the power to the each user.
