摘要： A method and apparatus provide for soft handoff operation of at least a first signal transmitted according to a first communication standard (IS-95B) and a second signal transmitted according to a second communication standard (IS-95C). A mobile station (104) initially receives the first signal, detects presence of a pilot signal, measures pilot signal strength, transmits a pilot strength measurement message, fails to receive a handoff direction message after transmitting the pilot strength measurement message, searches for detecting presence of a broadcast control channel associated with the type IS-95C cell sites, measures a carrier to interference ratio of the broadcast control channel, compares the carrier to interference ratio to a threshold, if the carrier to interference ratio is above the threshold, initiates a second communication according to IS-95C standard, thus, allowing initiating a soft handoff operation by allowing the base sites to transmit information according to the IS-95B and IS-95C standards respectively via the first and second signals. MS 104 combines the first and second signals to take advantage of the soft hand-off operation.

摘要： A method and apparatus for maximal-ratio combining of received frame data is provided. This technique increases the reliability of a communication network that includes multiple independent receivers. For example, when multiple independent receivers are not in agreement as to the received frame data (501, 502, 503), an embodiment of the invention provides a higher likelihood of correctly identifying the received frame data (501, 502, 503). A technique for determining a signal-to-noise ratio from a metric signal (504) derived from a decoder (701) in a receiver is provided. The signal-to-noise ratio may be characterized according to a polynomial estimate or stored in lookup table. The signal-to-noise ratio is used to apply a weighting (805) to “hard decision” data from the receiver to yield a weighted value (806). The weighted value is combined with weighted values from other receivers. The combined weighted values are applied to a data slicer (414) to yield received data (807).

摘要： Method and apparatus to provide a pseudo random noise (PN) sequence having a particular code phase offset for use in a radio in a Code Division Multiple Access (CDMA) radio system (100). In one embodiment, a first mask (320) is applied to shift a reference PN sequence to the assigned PN code phase (416). Upon reaching the end of the reference PN sequence, the initial state is reloaded (420) into the PN generator state register to reset the state value to its initial value, thereby producing a cyclical sequence. In a second embodiment, a first mask (622) and a second mask (624) are applied to the reference sequence produced by the PN generator state registers (620) to produce the appropriate portions of the output sequence.

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： In some implementations, a processor may retrieve predicted positioning data and predicted orbital data from global navigation satellite service (GNSS) positioning circuitry of a wireless device in response to a request for device time. The processor may retrieve long-term learning (LTL) data for a temperature sensing crystal (TSX) of the wireless device, the LTL data including S-curve characteristics of the TSX, and the time tracking uncertainty of the TSX. The processor may generate a GNSS-based device time estimate using the predicted positioning data and the predicted orbital data. The processor may perform TSX-based device time processing by updating the GNSS-based device time estimate using a clock signal of the TSX to generate a final device time estimate, the updating based on the retrieved LTL data for the TSX.

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.
