Patent ID: 8565138

Claim:
A method of coordinating communications between a wireless MIMO base station and a plurality of wireless communication devices, comprising: generating a series of index numbers for controlling sub-slot assignments for the plurality of wireless communication devices, each of the index numbers having a corresponding sub-slot in a communication structure of unit size; providing data representing the series of index numbers to the MIMO base station and each of the plurality of wireless communication devices; and controlling simultaneous communication between the plurality of wireless communication devices and the MIMO base station by reassigning access by the plurality of wireless communication devices to a plurality of sub-slots in the communication structure, wherein reassigning access comprises reassigning the plurality of wireless communication devices to different sub-slots from one successive time period to a next successive time period, wherein the different sub-slots are sub-slots corresponding to index numbers selected based on positions at which the index numbers occur within the series of index numbers.
