Abstract: In some embodiments, Satellite Positioning System (SPS) time information associated with at least one SPS may be maintained at a UE, which may also receive time information from a Wireless Wide Area Network (WWAN). In some embodiments, the UE may determine a corrected SPS time information for a first time based, in part, on the received WWAN time information, where the corrected SPS time information corrects the SPS time information associated with the at least one SPS maintained at the UE. The UE may initiate transmission of SPS timing assistance information to an associated device over a Wireless Personal Area Network (WPAN), wherein the SPS timing assistance information comprises the corrected SPS time information for the first time.
