摘要： The present invention is a method and apparatus for voice communication. Vocoded frames are transmitted using a transmission intervals. Each transmission interval is split into a first interval portion and a second interval portion. Code symbols associated with each vocoded frame are divided into a group A and a group B. The method includes transmitting group A code symbols of a first vocoded frame using a first interval portion of an interval i; decoding the group A code symbols received at the first interval portion of the interval i; performing an error detection code check on the first interval portion of the interval i; generating and sending a negative acknowledgment signal when the first interval portion of the interval i fails the error detection code check; and transmitting group B code symbols of the first vocoded frame using a second interval portion of an interval i+N.

摘要： A method and apparatus for communicating in an OFDM system whereby data subcarriers associated with a first antenna of at least two transmit antennas are multiplexed with data symbols while modulating other subcarriers associated with other antennas with zero. The data subcarriers are separated between the at least two transmit antennas so that a data subcarrier and a mirror data subcarrier are not transmitted from a same transmit antenna and that adjacent data subcarriers are at least two subcarrier frequency bandwidths apart. In an embodiment, the method and apparatus further comprise receiving the transmitted subcarriers from at least two receive antennas where the transmitted data subcarriers are also separated so that the data subcarrier and the mirror data subcarrier are not received from a same receive antenna of the at least two receive antennas. The method and apparatus further comprises combining the received transmitted subcarriers from the at least two receive antennas into a single data stream.

摘要： A method and apparatus for communicating in an OFDM system whereby subcarriers of the OFDM system are multiplexed between at least a first and a second transmit antenna. The subcarriers are separated between the at least two transmit antennas so that a subcarrier and a mirror subcarrier are not transmitted on the same transmit antenna and that adjacent subcarriers on the same antenna are at least two subcarrier frequency bandwidths apart. The method and apparatus for communicating is compatible with either a single receive antenna or with more than one receive antennas. In an embodiment, the method and apparatus further includes receiving the transmitted subcarriers from at least a first and second receive antenna. The subcarriers may also be separated so that the subcarrier and the mirror subcarrier are not received from the same receive antenna and that adjacent subcarriers on the same antenna are at least two subcarrier frequency bandwidths apart. The method and apparatus further includes combining the received transmitted subcarriers from the at least two receive antennas into a single data stream.

摘要： At a first device (102 or 104), a message is received and processed. If the message is processed during a first time period, the first device transmits an acknowledgement message during a second time period; otherwise the first device transmits the acknowledgment message during a third time period. The second time period and the third time period are exclusive of each other.

摘要： A receiving communication device synchronizes to a timing reference of a transmitting communication device based on a determined timing error. The receiving communication device determines the timing error by processing a synchronization signal via a first stage filtering and interpolation process that includes predetermined coefficients and a second stage interpolation process that includes a minimal number of dynamically determined coefficients. By dividing the process into a predetermined coefficient stage and a dynamically determined coefficient stage, the receiving communication device is able to make timing adjustments in a more efficient manner, that is, at a lesser processor loading, than a communication device in which all filtering and interpolation coefficients are dynamically determined. In addition, by including a second order timing recovery loop, the receiving communication device is able to quickly and precisely respond to drifting of a timing reference differential between itself and the transmitting communication device.

摘要： An access point (100) transmits at least a first set of parameters intended for a first set of users (102) and a second set of parameters intended for a second set of users (104). The access point communicates with the first set of users during a first time period and communicates with the second set of users during a second time period, wherein the first time period and the second time period are exclusive of each other. Moreover, the first time period and the second time period lapse prior to the AP transmitting a next set of parameters intended for the first set of users.

摘要： A communication system (100) that includes base stations (103-109) comprising selection circuitry (207) is provided herein. The determination of a call anchoring base station (base station performing Code Division Multiple Access (CDMA) frame selection) is made based on the base station with a lowest mean work load. During communication with a remote unit (113), frames received by non-call anchoring base stations (105, 107) are backhauled to a switch (101). The switch (101) then sidehauls the frames to the call anchoring base station (103), where selection and call processing functions for the particular call takes place.

摘要： A method and apparatus for compensating for input threshold variations in input buffers is provided. The method and apparatus compensate for input threshold variations by applying a bias voltage on a known capacitance of an RC calibration circuit using, for example, a pulse width modulator. The bias voltage helps ensure that the time to charge the known capacitance from the bias voltage to the input threshold voltage of the input buffer is independent of the threshold voltage. The bias voltage is chosen using an iterative process in which the time to charge from the bias voltage to the threshold voltage is compared with a reference time. The bias voltage is adjusted based on the comparison.

摘要： Aspects of the disclosure permit agile acquisition of a location service in a device. In one aspect of such acquisition, the device can rely on location signals available globally in order to determine a region associated with the device, and in response to determination of the region, the device can acquire service information representative or otherwise indicative of the location service based at least on the region. In another aspect, the device can be configured to consume the location service. The agility of such acquisition can stem from the absence of (i) scanning for location services associated with the area in which the device is present and/or (ii) a predefined pool of location services established in production of the device.
