摘要： Method, mobile device, computer program product, and apparatus for optimizing sensor reporting are described. A mobile device can measure radio frequency (RF) signal characteristics while receiving data from one or more mobile device sensors. The mobile device may determine its relative displacement between RF signal measurements. The mobile device can send a representation of the RF signal characteristics and the displacement data to one or more servers. The representation displacement data may include one or more reliability characteristics and/or a displacement reliability rating. A server can obtain the displacement data and RF signal characteristics to determine positioning of wireless transmitters in an environment and build a positioning database.

摘要： Systems and methodologies are described that facilitate identifying resources upon which an acknowledgment can be sent or received in a wireless communication environment that leverages coordinated multi-point (CoMP). The resources can be identified based upon a criterion that can be identifiable to a non-anchor cell base station (as well as an anchor cell base station, a mobile device, etc.). The criterion can be an identifier corresponding to a mobile device, where the identifier maps to a predetermined set of resources. Examples of the identifier can include a media access control identifier (MACID), a cell radio network temporary identifier (C-RNTI), a short C-RNTI, etc. Further, the criterion can be physical resources corresponding to a transmission, where the acknowledgment is responsive to the transmission. Moreover, the acknowledgment can be sent or received in connection with a cooperation technique (e.g., joint transmission via inter-site packet sharing, cooperative beamforming, cooperative silence, . . . ).

摘要： Techniques for performing network-assisted peer discovery to enable peer-to-peer (P2P) communication are described. In one design, a device registers with a network entity (e.g., a directory agent) so that the presence of the device and possibly other information about the device can be made known to the network entity. The network entity collects similar information from other devices. The device sends a request to the network entity, e.g., during or after registration. The request includes information used to match the device with other devices, e.g., information about service(s) provided by the device and/or service(s) requested by the device. The directory agent matches requests received from all devices, determines a match between the device and at least one other device, and sends a notification to perform peer discovery. The device performs peer discovery in response to receiving the notification from the network entity.

In some embodiments, a method may comprise obtaining the speeds of a plurality of mobile stations in a set of mobile stations connected to an AP in a wireless network. The frequency of Round Trip Time (RTT) measurements between a mobile station in the plurality of mobile stations and the AP is increased during periods when the speed of the mobile station does not exceed a threshold. An estimate of variability may be obtained for RTT measurements for the AP.

摘要： A method of wireless communication includes receiving position location reference signals (PRSs) from multiple remote radio heads (RRHs) and a macro eNodeB having a same physical cell identity (PCI). Each PRS is a same PRS. Additionally, the PRSs from the multiple RRHs are received on subframes that are different from subframes used by the macro eNodeB. Furthermore, each PRS does not indicate a source of transmission. The method also includes determining a time difference between the received PRSs.

摘要： Systems and methodologies are described that facilitate providing high reuse for transmitting reference signals, such as positioning reference signals (PRS) and cell-specific reference signals (CRS), to improve hearability thereof for applications such as trilateration and/or the like. In particular, PRSs can be transmitted in designated or selected positioning subframes. Resource elements within the positioning subframe can be selected for transmitting the PRSs and can avoid conflict with designated control regions, resource elements used for transmitting cell-specific reference signals, and/or the like. Resource elements for transmitting PRSs can be selected according to a planned or pseudo-random reuse scheme. In addition, a transmit diversity scheme can be applied to the PRSs to minimize impact of introducing the PRSs to legacy devices. Moreover, potions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.

摘要： Measurements are conducted on one or more carriers in a case where an access terminal supports reception on multiple carriers. Upon determining that an access terminal is capable of concurrently receiving on a given set of carriers, a measurement is conducted on one or more carriers of the set while receiving on or more other carriers of the set. Conversely, upon determining that an access terminal is not capable of concurrently receiving on a given set of carriers, a measurement is conducted on one or more carriers of the set while not receiving on or more other carriers of the set. In addition, data transfers to or from an access terminal on a carrier may be restricted (e.g., data transfers not scheduled or only low priority data transfers scheduled) during one or more subframes before or after the access terminal conducts a measurement on another carrier.
