Abstract
Techniques are provided for efficiently optimizing scheduling and beamforming in an OFDMA-based wireless network that uses SDMA. The techniques are capable of achieving a high level of spectral efficiency and throughput in a low complexity manner while still addressing quality of service (QoS) constraints.
