Patent ID: 8917675

Claim:
A system for wireless communication, the system comprising: a coordinator that schedules wireless transmissions among a plurality of wireless devices during a plurality of superframes, at least one of the superframes comprising a period during which the coordinator receives one or more data packets from the wireless devices via at least one random access scheme, the period being partitioned into a plurality of sub-periods which do not overlap with one another and are assigned to wireless transmissions in different directions from one another, wherein the coordinator receives at least a first data packet having a first value for a parameter during a first sub-period and a second data packet having a second value for the parameter during a second sub-period, wherein the first and second values for the parameter are different from each other, and wherein the plurality of sub-periods are dynamically partitioned based on different parameters that are selected by the coordinator, and each sub-period is associated with a different transmission direction for one or more transmissions from selected transmitting positions.
