摘要： A wireless local area network (WLAN) mobile station (110, 112, 114) has an application processor core (204) and a WLAN processor (202). So as to conserve energy, when the two processors are not needed, they are both placed in a minimal power consumption mode. The WLAN processor operates a WLAN radio and receives beacon transmissions from an access point (120). Upon extracting the beacon data from a received beacon signal, the WLAN processor passes the beacon data to the application processor. To ensure receipt of the beacon data, the WLAN processor remains active until the application processor acknowledges receipt of the beacon data before transitioning back to a sleep mode. To prevent keeping the WLAN processor waiting longer than necessary, the application processor wakes up ahead of the beacon receipt time, in time to allow transition to an awake mode so that it is active by the time the WLAN processor passes the beacon data.

摘要： A wireless station (114) is within range of more than one access point (120, 124) transmitting on the same channel. The wireless station is associated with one access point and not the other. Consequently the wireless station may receive undesired beacons (304) and desired beacons (302) on the channel. To optimize power save operation the wireless station arbitrates between a scan and shut down scanning procedure (708) and a timed window channel scanning procedure (724), depending on whether the desired beacon is the first received beacon upon waking up from a low power state at a target beacon time.

摘要： A power calibration scheme adjusts power levels of network of femtocells based on macro signals seen at different points in and around a coverage area and based on the mutual positions of the femtocells (e.g., based on femtocell signals seen at these points). The power calibration scheme thus facilitates a good balance between providing a desired level of coverage and mitigation of interference to nearby macrocells and femtocells.
