摘要:
A wireless remote unit performs SPS acquisition interleaved with receiving paging information over a wireless slotted paging channel and receiving data packets over a wireless data communication system. The remote unit tunes to a pilot channel, synchronizes to an internal clock of the wireless remote unit with a pilot signal transmitted over the pilot channel; and starts a search for SPS satellites after completing synchronization with the internal clock.
