A mobile wireless terminal (MWT) includes multiple wireless modems. The multiple modems have their respective transmit outputs combined together to produce an aggregate transmit output. The multiple modems can concurrently transmit data in a reverse link direction and receive data in a forward link direction. The MWT is constrained to operate under an aggregate transmit power limit. Each of the multiple modems has an individual transmit limit related to the aggregate transmit power limit. An MWT controller adjusts the individual transmit power limits in the multiple modems based on an aggregate transmit power limit of the MWT and respective transmit power estimates from the modems, to cause each individual transmit power limit to track a corresponding individual modem transmit power.

Controlling multiple modems in a wireless terminal using dynamically varying modem transmit power limits

This disclosure is directed to techniques for generating position assistance information that can be used by a subscriber unit of a wireless communication system. In accordance with this disclosure, a position determination entity (PDE), e.g., which may be coupled to one or more of the base stations, implements techniques that can improve the position assistance information, and therefore improve the ability of the subscriber unit to quickly and accurately identify its location using the positioning satellites. In particular, the PDE receives information from the subscriber unit indicative of signals detected by the subscriber unit in the wireless communication system, and then divides an area where the subscriber unit is suspected to be into a plurality of sectors. The PDE scores the sectors based on the information received from the subscriber unit, wherein a score for a respective sector indicates a likelihood that the subscriber is in the respective sector.
