摘要： A method for wireless communication using MAC PDUs. The method includes determining one or more characteristics of a service flow and selecting on the basis of the one or more characteristics a MAC PDU header type among a plurality of MAC PDU header types. The service flow data is encapsulated in MAC PDUs with a header of the selected type. The MAC PDUs with the encapsulated service flow data are then wirelessly transmitted. Also, a method for communication between a Base Station (BS) and a Subscriber Station (SS). The method includes generating at the BS a plurality of MAC PDU packets with a payload component holding service flow data and a plurality of MAC PDU packets without payload component, carrying control information. The method also includes transmitting wirelessly the MAC PDU packets with the payload component and the MAC PDU packets with the control information to the SS.

摘要： Soft handoff in an OFDMA system is disclosed. If the pilot signal strength for a base station exceeds the defined threshold, the base station is added to an active set list. Subcarriers in a plurality of orthogonal frequency division multiplexing (OFDM) symbols are divided and allocated into subchannels. The OFDM symbols are divided and multiplexed. A soft handoff zone with a first dimension of the subchannels and a second dimension of the divided and multiplexed OFDM symbols is defined. The soft handoff zone has subcarriers with a subchannel definition, for example, an identical permutation.
