摘要： A few high power tones used for synchronization and/or other purposes are transmitted in a FDM system during a period of time, e.g., a symbol transmission time period. During normal data transmission symbol periods signals are transmitted using at least 10 tones, e.g., per symbol time. Less than 5 high power signals are transmitted in a symbol time with at least 80% the maximum total transmitter power transmitted being allocated to the high power signals where the maximum total transmitter power is determined from a period of time which may includes one or more data and/or high power tone transmission periods. When the high power tones are transmitted at most 20% of transmitter power is available for transmitting other tones with the power normally being distributed among multiple tones. Normally some tones which would be transmitted in a symbol time go unused during transmission of the high power signals.

摘要： Methods and apparatus for simulating, in reduced resolution video decoders, the biasing effect associated with MPEG's specified rounding of pixel values including a fractional component of 0.5 to the next highest integer value are described. In one embodiment, the biasing effect is simulated by generating luminance and chrominance DC DCT coefficient bias values from, e.g., motion vector offset data. The DC DCT bias values are then added to the DC DCT coefficients of the luminance and chrominance blocks, respectively, which correspond to the same image block to which the motion vector data used to generate the bias values corresponds. In another embodiment, pixel values are directly adjusted to simulate the biasing effect associated with MPEG compliant rounding. In such an embodiment, luminance and chrominance pixel biasing values are generated as a function of, e.g., motion vector offset information. The bias values are added to the pixel values generated through the use of motion compensated prediction. The pixel values are then rounded by performing a non-biased rounding operation to generate integer pixel values.

摘要： A first mobile node supports peer to peer communications but not cellular communications. Other mobile modes in the communication system support a cellular mode and may support a peer to peer communications mode. The communications system is such that spectrum may be dynamically reallocated between being designated to be used for peer to peer operations and being used primarily for cellular network based operations. Beacon signals are used to communicate a current mode of frequency spectrum usage designation. The first mobile node, being in an ongoing peer to peer communications session detects that the spectrum is being reallocated for cellular based operations. The first mobile node reduces its transmission power level in response to the detected spectrum reallocation. In some embodiments, the first mobile is allowed to continue its ongoing peer to peer session while the spectrum is primarily allocated for cellular communications, albeit at a lower transmission power level.

摘要： A mobile communications device initiates a handoff from its current base station (BS) sector network attachment point to a new BS sector. The mobile sends a handoff request over its current wireless link to the current BS sector, which forwards the request to the new BS sector, e.g., via a network link. The new BS sector processes the request assigning dedicated resources, e.g., an identifier and dedicated uplink segments. Information identifying the allocated resources is conveyed from the new BS sector via the current BS sector to the mobile. The mobile determines the time of the allocated dedicated segments based upon a received beacon signal from the new BS sector with known timing relationships to dedicated segments. The mobile breaks the original wireless link just prior to the time of the first assigned dedicated segment. The mobile communicates information on the assigned dedicated segments to perform registration operations, e.g., timing synchronization and power control, establishing a new wireless link.

摘要： Downlink traffic channel data rate options and methods of indicating to a wireless terminal a utilized downlink data rate option are described. The downlink traffic channel rate option for a segment is conveyed using an assignment signal and/or a block in the downlink traffic channel segment which is not used for user data. Downlink segment assignment signals in some implementations allocate fewer bits for rate option indication than are required to uniquely identify each option. In some implementations low rate options, e.g., using QPSK, are uniquely identified via assignment signals. Higher rate options, e.g., using QAM16 modulation, are conveyed via the distinct information block in the downlink traffic segment using a first coding/modulation method. Still higher rate options, e.g., using QAM16, QAM64, or QAM256, are conveyed via the information block in the segment using a second coding/modulation method which is applied to the rate option information.

摘要： Methods and apparatus for controlling the communications between a wireless microphone receiver and one or more wireless microphone transmitters are described. In accordance with some embodiments a common control channel is used for communicating control signals between the wireless microphone receiver and one or more wireless microphone transmitters, while separate audio data channels are used to carry audio data traffic from each individual wireless microphone transmitter to the microphone receiver. In accordance with some other embodiment, a time division approach is used in which there are microphone transmit time periods and control signaling time periods. During the microphone transmit time periods, wireless microphone transmitters transmit audio data signals and, in some embodiment, control signals, to the wireless microphone receiver using separate frequency subbands within a frequency band. During control signaling time periods, the wireless microphone receiver transmits a control signal to a wireless microphone transmitter using the frequency band.

摘要： A wireless terminal using OFDM signaling supporting both terrestrial and satellite base station connectivity operates using conventional access probe signaling in a first mode of operation to establish a timing synchronized wireless link with a terrestrial base station. In a second mode of operation, used to establish a timing synchronized wireless link with a satellite base station, a slightly modified access protocol is employed. The round trip signaling time and timing ambiguity between a wireless terminal and a satellite base station is substantially greater than with a terrestrial base station. The modified access protocol uses coding of access probe signals to uniquely identify a superslot index within a beaconslot. The modified protocol uses multiple access probes with different timing offsets to further resolve timing ambiguity and allows the satellite base station access monitoring interval to remain small in duration. Terrestrial base station location/connection information is used to estimate initial timing.

摘要： Techniques for performing automatic gain control (AGC) at a receiver are described. The receiver may receive an OFDM-based symbol composed of a cyclic prefix and a useful portion. The receiver may scale the OFDM-based symbol with an initial receiver gain, adjust the initial receiver gain based on the cyclic prefix, apply the adjusted receiver gain prior to the useful portion, and process the useful portion to recover at least one signal sent by at least one transmitter. The receiver may select the initial receiver gain, e.g., based on a predicted received power level for the at least one transmitter, a pattern of different receiver gains, etc. The receiver may apply the initial receiver gain at the start of the OFDM-based symbol. The receiver may measure the power of a set of samples in the cyclic prefix and may adjust the receiver gain based on the measured power and a target power.
