摘要： Positions of non-reference wireless transceivers to be added to a wireless communication network are determined as follows. Each non-reference wireless transceiver performs measurements of times of arrival (TO A) of signals transmitted by other non-reference wireless transceivers, as well as reference wireless transceivers. Thereafter, time difference of arrival (TDOA) values are computed from at least two types of pairs of measurements as follows: (a) unknown-unknown TDOA values are obtained as differences between TOA measurements of signals transmitted by non- reference wireless transceivers and (b) unknown-known TDOA values are obtained as differences between a TOA measurement of a signal transmitted by a non-reference wireless transceiver and another TOA measurement of another signal transmitted by a reference wireless transceiver. Both types of TDOA values are used to solve simultaneous equations to identify the positions of the non-reference wireless transceivers and optionally times of transmission of the signals by the non-reference wireless transceivers.

摘要： Techniques for determining resources to use for peer-to-peer (P2P) communication are disclosed. In an aspect, a network entity may receive feedback information (e.g., resource usage information and/or channel state information) from P2P devices and may perform resource partitioning based on the feedback information to allocate some of the available resources for P2P communication. The allocated resources may observe little or no interference from devices engaged in wide area network (WAN) communication. In another aspect, P2P groups may perform resource negotiation via a WAN connection (e.g., with little or no involvement by the WAN) to assign the allocated resources to different P2P groups. In yet another aspect, a device may autonomously determine whether to communicate with another device directly or via a WAN, e.g., whether to initiate P2P communication with another device and whether to terminate P2P communication. In yet another aspect, a network entity may participate in resource negotiation by P2P devices.
摘要翻译：公开了用于确定用于对等（P2P）通信的资源的技术。在一方面，网络实体可以从P2P设备接收反馈信息（例如，资源使用信息和/或信道状态信息），并且可以基于反馈信息执行资源划分，以分配用于P2P通信的一些可用资源。分配的资源可能观察到从事广域网（WAN）通信的设备的干扰很小或没有。在另一方面，P2P组可以经由WAN连接进行资源协商（例如，很少或没有WAN的参与）来将分配的资源分配给不同的P2P组。在另一方面，设备可以自主地确定是直接地还是经由WAN与另一设备通信，例如是否发起与另一设备的P2P通信以及是否终止P2P通信。另一方面，网络实体可以参与P2P设备的资源协商。

摘要： Techniques for supporting peer-to-peer (P2P) communication and wide area network (WAN) communication are disclosed. In one aspect, P2P communication may be supported on an uplink spectrum. A user equipment (UE) may communicate (i) with a base station on both a downlink spectrum and an uplink spectrum for WAN communication and (ii) with another UE on only the uplink spectrum for P2P communication. In another aspect, P2P communication may be supported by time division multiplexing the downlink and uplink (or transmit and receive links) for two UEs. In yet another aspect, WAN communication and P2P communication may be time division multiplexed, so that both can be concurrently supported by a UE. In yet another aspect, transmission gaps may be provided between WAN transmissions and P2P transmissions in order to avoid interference between these transmissions.

摘要： Techniques for mitigating interference due to peer-to-peer (P2P) communication are described. In an aspect, a P2P UE may measure the signal strength of downlink signals from base stations and may set its transmit power based on (e.g., proportional to) the measured signal strength in order to mitigate interference to WWAN UEs communicating with base stations. In another aspect, the P2P UE may measure the signal strength of uplink signals from WWAN UEs and may set its transmit power based on (e.g., inversely proportional to) the measured signal strength in order to mitigate interference to the WWAN UEs. In one design, the P2P UE may measure the signal strength of an uplink signal from a WWAN UE, estimate the pathloss between the two UEs based on the measured signal strength, and determine its transmit power based on the estimated pathloss.

摘要： Systems and methodologies are described that facilitate mitigating intercarrier and intersymbol interference in symbol transmissions over wireless communications where transmitter and receiver may not be time synchronized. Symbol periods can be extended for transmitting symbols such that an original symbol can be transmitted with one or more duplicated symbols keeping phase continuous, blank symbols, and/or the like. In this regard, multiple receiver windows can be required to receive the symbol such that at least one window has a non-interfered symbol even though timing can be misaligned (e.g., in asynchronous communications channels).

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 sub frames. Resource elements within the positioning sub frame 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： Techniques for centralized control of peer-to-peer (P2P) communication and centralized control of femto cell operation are described. For centralized control of P2P communication, a designated network entity (e.g., a base station) may control P2P communication of stations (e.g., UEs) located within its coverage area. The designated network entity may receive an indication of a first station (e.g., a UE) desiring to communicate with a second station (e.g., another UE). The designated network entity may determine whether or not to select peer-to-peer communication for the first and second stations, e.g., based on the quality of their communication link. The designated network entity may assign resources to the stations if peer-to-peer communication is selected. For centralized control of femto cell operation, the designated network entity may control the operation of femto cells (e.g., may activate or deactivate femto cells) within its coverage area.
