A method and apparatus determines a physical location of a wireless infrastructure device. At least one coarse location data from an associated terminal device is determined. Additional coarse location data are stored and accumulated. The device location is considered accurate by determining that enough received coarse location data has been received.

Apparatus and methods for wireless communication transmission power control are provided. Determination of gain factors and adjustments for physical channel reconfiguration in the context of transmission power control are addressed. Preferably, implementation is in conjunction with communication systems in which wireless communications are conducted between wireless transmit receive units (WTRUs) using multiple channels that are concurrently transmitted.

The present invention is related to a method and system for preventing high speed downlink packet access (HSDPA) transmission loss due to transmission gap in compressed mode in a wireless transmit/receive unit (WTRU). In accordance with one embodiment, a Node-B receives a compressed mode transmission gap schedule of a WTRU, identifies HSDPA transmission time intervals (TTIs) that are affected by the WTRU compressed mode transmission gap schedule and schedules the HSDPA transmissions not to overlap the WTRU compressed mode transmission gap schedule. In accordance with another embodiment, the Node-B may inform the HSDPA transmission schedule to a radio network controller (RNC) and the RNC coordinates the HSDPA transmission schedule and a compressed mode transmission gap schedule of the WTRU.
