Patent ID: 8340601

Claim:
A method, comprising: transmitting, from a first of multiple antennas, training signals directionally in each of multiple sectors; repeating said transmitting from each of a remainder of the multiple antennas; receiving, from each of multiple mobile devices (MDs), information containing a sector identifier and an associated received signal strength indicator (RSSI) for each training signal received by said each of the multiple MDs; locating each of the multiple MDs in a particular sector, based on the received RSSIs; determining, for each sector, a signal-to-interference-and-noise ratio (SINR) for each combination of a transmission to that sector from one antenna and a transmission to another sector from another antenna; determining non-interfering combinations of sectors, based on said SINRs; and allocating the MDs into groups, with each group containing a maximum of one MD per sector for sectors whose SINR indicates simultaneous transmissions to all the MD's in the group from different antennas will not result in mutual interference.
