摘要： Receivers accommodating carrier frequency selection methods in wireless communications systems employing multiple carrier frequencies are described. Although the receiver is tuned to a single band, an estimate of the channel quality corresponding to the currently used carrier and an alternative carrier is generated without switching between carriers. Transmitters of different cells and/or different sectors primarily use different carrier frequencies but periodically transmit using a neighboring sector's carrier frequency. Mobile node receivers use a single RF chain with a controllable RF filter to receive and process a signal within a first selected carrier band including two components, a first signal component identified with the first currently selected band and a second signal component identified with a second alternative band. Separate quality indicator values are obtained from the first and second signal components, compared, and a determination is made as to whether the receiver's RF filter should be switched to the second band.

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： System and method for providing a timestamp packetized data interface between an RF unit and a modem. According to one embodiment, the RF unit receives an inbound RF signal, processes and demodulates the inbound RF signal to generate samples, generates a timestamp indicative of when the inbound RF signal was received, packetizes and multiplexes the samples and the timestamp, and sends the multiplexed stream to the modem. The modem generates received data from the samples. If the received data type requires a response to be sent at a particular time, the modem generates symbols from responsive outbound data, generates a timestamp which indicates when the outbound data is to be transmitted, packetizes and multiplexes the symbols and the timestamp, and sends the multiplexed stream to the RF unit. The RF unit generates an outbound RF signal from the symbols, and transmits the outbound signal in accordance with the timestamp.

摘要： Signal detectivity is improved by implementation of address adjustment to reorder samples and to discard undesired samples. Such reordering is utilized when the time order of received samples are distorted and/or corrupted, which can occur in at least three situations. If the samples are distorted in time order, the samples are rearranged to allow the samples to return to proper order. The samples, if corrupted, are discarded and replaced with zero samples.

摘要： Apparatus and methods for updating symbol information in a communication device with hardware such as a microcontroller are disclosed. The disclosed apparatus and methods employ waiting for the beginning of a symbol in a sample stream at a predetermined time. One or more programmed instructions are read at the beginning of the symbol, and then symbol information is updated based on the one or more programmable instructions and setting a time for a beginning of a next symbol. The programmed instructions consist of instruction code words that are executed by a dedicated microcontroller or similar hardware, which affords flexibility for updating symbol information, particularly for multimode communication devices operable across multiple communication technologies.

摘要： Methods and apparatus for insuring that a trick play data stream, e.g., a stream of data used for fast forward or reverse playback operation, complies with preselected data standards and in particular the MPEG-2 standard are disclosed. Various methods are described for generating PCR, PTS and DTS values for a trick play data stream, which is generated from a normal play data steam, and is intended for recording in trick play segments of a tape. The described methods include generating new PCR, PTS and DTS values as a function of the trick play speed at which the data is intended to be read back. Methods and apparatus for correcting PCR, PTS and DTS values read from a tape during trick playback operation are also disclosed. The disclosed methods are directed to generating new PCRs, PTSs and DTSs to provide am MPEG-2 compliant bitstream. The described methods and apparatus are applicable to a plurality of storage and playback devices capable of implementing trick play including compact disks.

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.
