摘要： A set of signal prediction map generation parameters, used to generate a signal prediction map to determine mobile device location, are initially modeled as large variance random variables. A network device, e.g., a server, receives estimated positions of mobiles and corresponding signal measurements, e.g., received signal power measurements, taken at those estimated positions by the mobiles. Received signal measurement information and corresponding estimated position information from a mobile is used to update one or more of the signal prediction map generation parameter distributions. After multiple updates to a distribution of a signal prediction map generation parameter, the network node transmits a prediction parameter update signal communicating the new distribution of the signal prediction parameter to be subsequently used by the mobile devices in the system when generating a signal prediction map and estimating its position.

摘要： Various embodiments are directed to methods and apparatus for mobile device position determination and the efficient communication of mobile device position related information. In different areas different types of reference signals may be available to be used by a mobile device for position determination. Some types of references signal may be well suited for short range in an indoor environment, e.g., audio signals, Bluetooth signals and Wi-Fi signals, while other types of signals may be well suited for an outdoor environment, e.g., GPS signals and cellular base station signals. Different types of signals may facilitate different possible resolution accuracies for a position determination. In various embodiments, in different areas within a geographic coverage region, different sets of reference signals are available to be used by a mobile wireless device to determine its position.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus generates a codeword, determines at least one puncture to the codeword based on allowing a legacy receiver to decode the codeword without knowledge of the at least one puncture, replaces each of the at least one puncture with a pilot, and transmits the codeword. The apparatus may also generate an IEEE 802.11 codeword having pilots in a first set of subcarriers, and puncture the codeword with additional pilots unknown to a legacy receiver in a second set of subcarriers. Accordingly, when an original set of pilot symbols is insufficient or inappropriately placed in a resource structure, a codeword may be transmitted with a new pilot structure capable of being decoded by legacy receivers not aware of the new pilot structure.

摘要： Various methods and apparatus are directed to collision detection and/or avoidance regarding peer to peer connection identifiers. A wireless communications device broadcasts a signal indicating its acquired connection identifier in one of two alternative blocks. A base station monitors peer to peer signaling in its coverage area and tracks the usage of peer to peer connection identifiers by pairs of devices. The base station detects when multiple pairs of devices are using the same peer to peer connection identifier. The base station provides assistance to the peer to peer network to avoid a collision or facilitate rapid collision detection by the peer to peer devices. In one approach the base station sends an instruction for a connection to switch its connection identifier. In another approach the base station sends a connection a message to bias its selection as to which of the two alternative blocks to use for transmission.

摘要： A method of operating a first wireless device includes receiving a grant from a base station for peer-to-peer communication with a second wireless device using time-frequency resources utilized by a third wireless device for WWAN communication with the base station. In addition, the method includes receiving a transmit power for the peer-to-peer communication with the grant. The transmit power is determined based on an interference that can be caused to transmissions received by the base station from the third wireless device. Furthermore, the method includes communicating with the second wireless device at a power less than or equal to the received transmit power using peer-to-peer communication on the time-frequency resources.

摘要： A communications device synchronizes itself with respect to an external reference signal, e.g., a GPS signal. The communications device detects timing reference signals, e.g., beacon signals, from a communications network. If the communications device determines that the network is not synchronized to the external timing reference signal, the communications device operates as a master timing control device. In various embodiments, when operating as a master timing control device the wireless communications device communicates time stamps, e.g., in beacon signals, which indicate a greater passage of time than the actual passage of time. When operating as a master timing control device the communications device transmits network timing reference signals at a higher rate than is being used by the network to seize control of network timing and become the master timing control device. The communications device drives the network timing to synchronize network timing to the external timing reference.
