System and method for multiple contention access periods
First Claim
1. 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, andwherein 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.

Abstract
A system and method for multiple contention access periods is disclosed. In one embodiment, the system for wireless communication comprises a coordinator configured to schedule 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 is configured to receive 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, wherein the coordinator is configured to receive 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, and wherein the first and second values for the parameter are different from each other.

28. An electronic device for wireless communication, the device comprising:
-
a transmitter wirelessly transmits a data packet to a coordinator during a contention access period of at least one of a plurality of superframes, the contention access period comprising a plurality of non-overlapping sub-contention access periods, wherein the sub-contention access periods are each assigned to wireless transmissions in different directions from one another for one or more transmissions from selected transmitting positions, wherein the plurality of sub-contention access periods are dynamically partitioned based on different parameters, and each sub-contention access period corresponds to a different sector of an antenna; and a receiver receives information on the plurality of sub-contention access periods, wherein the transmitter sends the data packet during one or more of the plurality of sub-contention access periods based at least partly on the received information. - View Dependent Claims (29, 30)

31. A method of wireless communication in a wireless network, the method comprising:
-
receiving a first data packet having a first value for a parameter during a first sub-contention access period of a superframe, wherein the superframe comprises a contention access period, wherein the contention access period comprises the first sub-contention access period and at least a second sub-contention access period, the first and second sub-contention access periods being non-overlapping with each other and are assigned to wireless transmissions in different directions from one another; and receiving a second data packet having a second value for the parameter during the second sub-contention access period, wherein the first and second values for the parameter are different, wherein the first and second of sub-contention access periods are dynamically partitioned based on different parameters, and each sub-contention access period is associated with a different transmission direction for one or more transmissions from selected transmitting positions. - View Dependent Claims (32, 33, 34, 35, 36)
