Abstract: Systems and techniques are disclosed wherein a gated pilot signal can be acquired faster by checking the neighbor pilot signals of the target pilot signal. A subscriber station may frequency lock onto a wrong pilot burst because a partial correlation exists between the wrong pilot burst and an adjacent pilot burst. Comparing the strength of the target pilot signal with the strength of neighbor pilot signals enables the selection of the strongest pilot signal before the timely process of frequency locking and demodulation are initiated. Grouping pilot signals with the same symbol sequence and a pseudo-random noise increment apart enables quick acquisition of a gated pilot signal.

Abstract: In a system for mobile wireless communication, it is desirable to minimize the period of time during which the RF circuitry is powered (i.e. the RF power period). A novel method and apparatus for pilot monitoring during standby mode defers processing of pilot search results until the RF power period has passed. This approach allows more searches to be performed without extending the RF power period, thus improving idle handoff performance without reducing battery charge life.

Abstract: A system and method of conducting wireless communications between a wireless communication device (WCD) and both a first network (e.g., IS-2000) supporting voice and data services and a second network (e.g., IS-856) supporting packet data services. The method comprises providing the WCD with a primary transceiver and a secondary receiver for conducting wireless communications in a spatial diversity for the second network traffic or broadcast; disabling the secondary receiver and spatial diversity before a paging slot or 1x system acquisition and synchronization attempts; tuning the secondary receiver to a first network carrier frequency to perform first network activities; and retuning the secondary receiver to a second network carrier frequency for spatial diversity after performing the first network activities. The first network activities may include pilot set maintenance, overhead message maintenance, page match detection, or 1x system acquisition and synchronization attempts.

Abstract: A novel and improved method and apparatus provide for controlling an operation of an access terminal while processing a signal from an access point in a communication system. Various aspects of the invention provide for an access terminal to disable a handoff process when its demodulator or decoder is operating to demodulate or decode a control message received from an access point. The operation of the access terminal is controlled in a manner that prevents terminating prematurely the demodulation and decoding process of a control signal by a handoff process. As a result, the access terminal may continue operating in a normal wake up/ sleep cycle period while conserving its battery power.

Abstract: A wireless mobile telephone (400) is operated so as manage the performance of “off-frequency searches,” that is, searches for base station pilot signals that differ in frequency from the pilot signals in the mobile station's active set. Whenever frequency searching is performed (such as responsive to emerging from a reduced-power sleep mode), the mobile station performs on-frequency pilot signal searching (902) upon a prescribed active set frequency. Only if a prescribed off-frequency searching condition (903-908) is satisfied, the mobile station additionally performs off-frequency pilot signal searching (912) upon one or more neighboring base stations' frequencies.

Abstract: A system and method of improving wireless communications between a wireless communication device and both a first network supporting voice and data services and a second network supporting packet data services. The method comprises providing the WCD with a primary transceiver and a secondary receiver for conducting wireless communications in both a simultaneous-mode and a hybrid-mode; performing simultaneous-mode-to-hybrid-mode and hybrid-mode-to-simultaneous-mode transitions based on a performance metric; and evaluating the performance metric to determine whether to perform the mode transitions. In the simultaneous-mode, the primary transceiver conducts wireless communications in the second network and the secondary receiver conducts wireless communications in the first network. In the hybrid-mode, the primary transceiver use is time multiplexed during all of the first and second networks communications combinations. When the metric measures below a threshold, the WCD reverts from one mode to another mode at paging slot wake-ups.

Abstract: A method and apparatus for improving the performance of a convolutional encoder used in a slotted mode communication system. In a typical slotted mode communication system a stream of continuously convolutionally encoded symbols is transmitted by a base station. A remote unit, comprising a convolutional decoder to decode the stream of symbols periodically transits between active and inactive states. While in the inactive state the remote unit misses a portion of the continuous stream of symbols. Following the interruption of the stream of symbols, the state metrics of a trellis within the decoder are initialized. Initialization of the state metrics may be such that the decoding process will be biased towards only valid states and away from invalid states. In addition, the initialization may be such that there is not a bias towards any particular state within the trellis.
