Patent ID: 8259662

Claim:
A method for base station operation in a wireless communications system, the wireless communications system having a mobile station, the method comprising: transmitting a first boundary indication to the mobile station, wherein the first boundary indication is based on a position of a boundary; transmitting a position indication to the mobile station, the position indication corresponding to an assigned network resource assigned based on a network resource request, the position indication being relative with respect to the first boundary indication; transmitting a second boundary indication to the mobile station in response to detecting a change in the position of the boundary, wherein the second boundary indication is based on a changed position of the boundary; and transmitting a first transmission to the mobile station using a network resource corresponding to the position indication or receiving a second transmission from the mobile station using a network resource corresponding to the position indication, wherein the position indication is relative to the second boundary indication, wherein the boundary comprises a boundary between a downlink region and an uplink region of a frame, a boundary between two consecutive permutation zones in a downlink region or an uplink region of a frame, a boundary between two resource blocks both of which allocate network resources over a common period in the time-domain, or a boundary between mobile station traffic of different half-duplex frequency division duplex (H-FDD) groups.
