Abstract: Various techniques are disclosed for unambiguously determining and tracking frame offset in asynchronous wireless communication user equipment. The user equipment determines the unambiguous connection frame number of a downlink channel. The equipment then determines frame timing information for neighbor cells. The frame timing information for the primary common control physical channel and uplink dedicated physical channels is determined. The frame timing is determined as a coarse resolution frame offset in conjunction with a fine resolution chip offset. The frame numbering information for the uplink and downlink dedicated physical channels and the primary common control physical channel is also determined. Then the frame number and timing information is updated using a counter accurate to one chip resolution. The frame offset is updated if the number of chips underflows or overflows a predetermined window. Frame timing may be updated by updating only the fine chip offset or may be completely determined.

Abstract: An access terminal (102) reacquires a system frame number (SFN) when a difference between a continuous counter elapsed time (220) and a calculated elapsed time (222) exceeds a threshold. The continuous counter elapsed time (220) is generated by a continuous counter (122) remaining active during a sleep state of the access terminal (102) and the calculated elapsed time (222) is based on a SFN derived from a counter value generated by a discontinuous counter (124) that is deactivated during the sleep state. In one aspect, the continuous counter (122) may be clocked by a continuous clock (118) during a sleep mode and the discontinuous counter (124) may be clocked by a faster clock (120) that is deactivated during the sleep mode. During reactivation after the sleep mode, the discontinuous counter (120) is set, at the counter set time, to a reset counter value (126) corresponding to an SFN indicated by the continuous counter (122).

Abstract: Techniques for reducing search time using known scrambling code offsets are disclosed. In one embodiment, a plurality of search results is generated by correlating a received signal with a synchronization sequence. The plurality of search results is reduced by removing any results within a stored threshold. Further, the plurality of search result is reduced by removing those results already detected in a previous analysis.

Abstract: A terminal communicates with a first wireless network and obtains a list of cells in a second wireless network to measure. The terminal operates in a compressed mode and receives multiple transmission gap pattern sequences for different measurement purposes, e.g., RSSI measurements, BSIC identification, and BSIC re-confirmation. The terminal utilizes each transmission gap for its designated purpose or an alternate purpose. For each transmission gap, the designated purpose for the transmission gap is ascertained, and whether the transmission gap is usable for an alternate purpose is also determined based on at least one criterion. The transmission gap is used for the alternate purpose if the at least one criterion is satisfied and is used for the designated purpose otherwise. For example, a transmission gap designated for RSSI measurement may be used for BSIC identification, a transmission gap designed for BSIC identification or BSIC re-confirmation may be used for RSSI measurement, and so on.
