ORTHOGONAL RESOURCE REUSE WITH SDMA BEAMS

摘要

A wireless communication system can implement beamforming across multiple omni-directional antennas to create beams at different spatial directions. The communication system can arrange the beams in sets, with each set arrang ed to provide substantially complete coverage over a predetermined coverage area. The communication system can arrange the multiple SDMA beam sets to su pport substantially complementary coverage areas, such that a main beam from a first set provides coverage to a weak coverage area of the second beam se t. The wireless communication system assigns or otherwise allocates substant ially orthogonal resources to each of the beam sets. The wireless communicat ion system allocates resources to a communication link using a combination o f beam sets and substantially orthogonal resources in order to provide impro ved coverage without a corresponding increase in interference.
