    摘要: A method and apparatus of synchronization and frame structure determination of a base station are disclosed. One method includes the base station determining an initial frame structure including an active region and a dummy region, wherein the regions are sets of OFDM symbols.

The base station adjusts its frame structure based at least in part on the timing information, wherein adjusting its frame structure includes at least one of adjusting the active region and the dummy region. The base station adjusts its internal timing to improve synchronization with the second base station based on the timing error information.

    摘要: A method and apparatus of link adaptation of a broadcast system is disclosed. The method includes a base station adaptively determining a signal quality threshold. The base station broadcasts a signal, wherein the signal includes the signal quality threshold. A plurality of subscribers receives the signal, and measure a signal quality. Each of a subset of the plurality of subscribers transmits back to the base station an indicator of whether the received signal has a measured signal quality that is either above or below the signal quality threshold. A percentage of subscribers that receive the signal having a received signal quality above the signal quality threshold is estimated. A transmission modulation format and coding is selected based on the estimated percentage.

    摘要: A method and apparatus for estimating frequency offset and timing offset of a first Mobile Station (MS) in a communication system is provided. The method includes receiving a composite signal at a plurality of receiver antennas of a Base Transceiver Station (BTS). The composite signal includes a first signal transmitted from a first MS and a second signal transmitted from a second MS. The composite signal includes one or more tiles. Each tile includes a plurality of data sub-carriers, a plurality of first pilot sub-carriers, and a plurality of second pilot sub-carriers. A total phase offset of the first MS is estimated based on a complex conjugate product of pilot symbols of the plurality of first pilot sub-carriers. Thereafter, a first phase offset corresponding to the timing offset of the first MS is estimated based on a Power Delay Profile (PDP) of one or more first pilot sub-carriers. Finally, a second phase offset corresponding to the frequency offset of the first MS is determined based on the total phase offset and the first phase offset.
