摘要： A system and method for multiplexing subchannels in an OFDMA network is provided. The subchannels can be multiplexed by splitting the subchannels in the frequency domain. Alternatively, the subchannels can be code division multiplexed using N orthogonal spreading codes. The subchannel multiplexing increases system capacity for low-rate services, such as voice-based services.

摘要： A system and method for handoff are provided. A mobile station performs a make-before-break handoff of a control channel between a serving and target base station and a break-before-make handoff of a traffic channel between the serving and target base stations. The traffic channel handoff is performed after the control channel handoff has completed.

摘要： Methods and apparatus for notifying mobile stations in an inactive state of the presence of uplink or downlink channel configuration, broadcast system updates, traffic channel allocations and paging messages are provided. The notification can be provided in an information element in the same channel as the frame, or in a different channel. The information element identifies a subsequent frame which includes broadcast or configuration changes. The notifications for traffic channel allocations can include a first field, which identifies whether there are any traffic channel allocations for any sleep mode mobile station, and a second field for identifying the particular sleep mode mobile stations which are to receive traffic channel allocations. Notifications for paging messages can include a field, which identifies whether there are any paging messages for any idle mode mobile stations, and use second field to identify the particular idle mode mobile stations, which are to receive the paging messages.

摘要： Systems and methods for allocating traffic and associated control channels are provided. A downlink traffic control message can include an identification of a downlink traffic channel and an identification of an associated uplink control channel. An uplink traffic control message can include an identification of an uplink traffic channel and an identification of an associated downlink control channel in a frame subsequent to the frame of the uplink traffic channel. The associated control channels can be a feedback channel, which can provide power control information, retransmission request information, channel quality indication information and/or the like.
