Abstract: 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.

Abstract: In a radio frequency (RF) receiver, a receiver RF chain is tuned to a first (e.g., global positioning system (GPS)) channel to permit receipt of a first (e.g., GPS) signal over the first (e.g., GPS) channel on the receiver RF chain during a first time duration. The receiver RF chain is tuned to a second (e.g., cellular page) channel to permit receipt of a second (e.g., cellular page) signal over the second (e.g., cellular page) channel on the receiver RF chain during a second time duration, following the first time duration. The first (e.g., GPS) signal is processed during the first time duration and the second time duration, without any apparent interruption of the first (e.g., GPS) signal during the second time duration. The processing, for example, treats the actual interrup-tion as a temporary, short term fade of the first (e.g., GPS) signal during the second time duration, or provides a bridge signal (e.g., an estimated GPS signal on the receiver RF chain or an actual GPS signal received on another receiver RF chain) during the second time duration.

Abstract: Apparatus, and method for adaptive discovery and scanning of wireless access points (105-109). In one embodiment, a set of channels can be scanned (305) in a first iteration to discover wireless access points. In one embodiment, a discovery profile based on the discovered wireless access points can be determined (310) and in a second iteration, a subset of the set of channels can be scanned (315). In one embodiment, the subset consists of non-overlapping channels selected (315) according to the discovery profile.
