摘要： Methods and apparatus for base-station-assisted handover between WiMAX (Worldwide Interoperability for Microwave Access) and CDMA (Code Division Multiple Access) EVDO (Evolution-Data Optimized) or 1xRTT (one times Radio Transmission Technology, or 1x) networks during normal operation of a dual-mode mobile station (MS) are provided. By having a base station (BS) using one radio access technology (RAT) broadcast information about a BS in a neighboring cell employing a different RAT, the methods and apparatus may improve service continuity during handover.

摘要： A method for efficiently performing ranging in a wireless communication network may be implemented by a mobile station. The method may include sending a ranging code to a base station. The method may also include receiving a ranging response message from the base station. The method may also include determining whether a ranging failure condition is satisfied. The ranging failure condition may relate to something other than a duration of time. The method may further include re-sending the ranging code to the base station if the ranging failure condition is satisfied.

摘要： An appliance facilitates localization of a station (STA) in a network, for example, a short-range wireless network. An automatic response to a request for a measurement related communication is provided. The appliance can include a radio frequency (RF) interface and a media access control (MAC) section. The MAC section can receive the request and generate the automatic response immediately after a uniform period that is uniform among any such appliance within the network. The appliance performs only the generation of the automatic response, though the response can include additional information such as (x, y) coordinates of the appliance.

摘要： Noise and interference can be independently measured in a multiple user Orthogonal Frequency Division Multiplexing (OFDM) system. Co-channel interference is measured in a frequency hopping, multiple user, OFDM system by tracking the sub-carriers assigned to all users in a particular service area or cell. The composite noise plus interference can be determined by measuring the amount of received power in a sub-carrier whenever it is not assigned to any user in the cell. A value is stored for each sub-carrier in the system and the value of noise plus interference can be a weighted average of the present value with previously stored values. The noise component can be independently determined in a synchronous system. In the synchronous system, all users in a system may periodically be prohibited from broadcasting over a sub-carrier and the received power in the sub-carrier measured during the period having no broadcasts.

摘要： The subject matter disclosed herein relates to a system and method for receiving, by a first mobile station, a signal transmitted from a second mobile station and addressed to a communication device (e.g., a communication device having a known location). The signal comprises a location estimate for the second mobile station. A range from the first mobile station to the second mobile station is estimated based at least in part on a measured signal strength of the received signal.
