摘要： Techniques for using virtual noise figure for various functions in a wireless communication network are described. A virtual noise figure is an indication of a virtual noise level at a receiver, which may be higher than an actual noise level at the receiver. In an aspect, virtual noise figure may be used for serving base station selection. A terminal may receive information indicative of a virtual noise figure for each of at least one base station. The terminal may select a serving base station based on the virtual noise figure for each base station. The terminal may send data to the serving base station at a rate selected based on an actual noise figure for the serving base station. In other aspects, virtual noise figure may be used for interference management and/or power control.

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.
摘要翻译：描述了便于提供用于传输参考信号（诸如定位参考信号（PRS）和小区特定参考信号（CRS））的高重用以提高其对诸如三边测量等应用的可用性的系统和方法。具体而言，PRS可以在指定或选定的定位子帧中传输。定位子帧内的资源元素可以被选择用于发送PRS，并且可以避免与指定的控制区域，用于发送小区特定的参考信号的资源元素等的冲突。用于传输PRS的资源元素可以根据计划或伪随机重用方案来选择。另外，可以将发射分集方案应用于PRS以最小化将PRS引入到传统设备的影响。而且，未被指定用于PRS传输的子帧部分可以用于用户平面数据传输。

摘要： Providing for improved access communication for wireless systems is described herein. By way of example, wireless devices can employ wireless resource re-use in selecting a subset of access communication resources, to mitigate interference on uplink access requests. Re-use can be based on current network conditions, or on a type of base station facilitating the wireless communication. In some aspects, planned resource re-use can be facilitated by an access terminal. The access terminal requests neighboring or interfering network access points to reserve a set of resources for a serving access point. Reserved resources can be conveyed to the serving access point with an uplink access probe, to further mitigate interference.

摘要： In an access point identifier configuration scheme, different procedures are used for configuring (e.g., updating) different types of access points. For example, the criteria used to determine which identifiers are to be assigned to mobile access points may be different than the criteria used to determine which identifiers are to be assigned to stationary access points.

摘要： Systems and methodologies are described that facilitate employing distributed frequency planning and reuse factor optimization based upon forward link and/or reverse link interference management techniques. An optimal reuse factor for a base station can be determined based upon a metric that evaluates levels of service associated with neighboring base stations. Moreover, a subset of available resource sets can be selected for use by the base station; thus, a base station specific collection of resource sets can be formed through such selection. Further, mappings of each resource set to a set of physical resources can be disseminated in a network or portion thereof. According to another example, frequency hopping can be constrained to use of resources within a resource set (rather than across more than one resource set) as provided in a base station specific hopping pattern.
摘要翻译：描述了有助于采用基于前向链路和/或反向链路干扰管理技术的分布式频率规划和重用因子优化的系统和方法。可以基于评估与相邻基站相关联的服务等级的度量来确定基站的最佳重用因子。此外，可以选择可用资源集的子集供基站使用; 因此，可以通过这样的选择来形成基站特定资源集合。此外，每个资源集合对一组物理资源的映射可以在网络或其一部分中传播。根据另一示例，跳频可以被限制为使用资源集合（而不是跨越多于一个资源集合）的资源，如在基站特定跳频模式中所提供的。

摘要： Providing for interference reduction and/or avoidance utilizing backhaul signaling between wireless access points (APs) of a wireless access network (AN) is described herein. By way of example, an interference avoidance request (IAR) can be issued by an AP to reduce signal interference on forward link (FL) and/or downlink (DL) transmissions by neighboring APs. The IAR can be routed via a backhaul network and/or over-the-air via access terminals (ATs) coupled with the AP or one or more interfering APs. Upon receiving the IAR, an interfering AP can determine reduced transmit power levels for FL and/or RL transmissions and respond to the IAR. The response can include reduced power levels and can be sent via the backhaul network or OTA. By employing the backhaul network in full or in part, interference avoidance can be conducted even for semi-planned or unplanned heterogeneous networks coupled by the backhaul.
摘要翻译：这里描述了利用无线接入网络（AN）的无线接入点（AP）之间的回程信令来提供干扰降低和/或避免。举例来说，AP可以发布干扰避免请求（IAR）以减少相邻AP的前向链路（FL）和/或下行链路（DL）传输上的信号干扰。 IAR可以经由回程网络和/或经由与AP耦合的接入终端（AT）或一个或多个干扰AP在空中路由。一旦接收到IAR，干扰AP可以确定用于FL和/或RL传输的降低的传输功率电平并响应IAR。响应可以包括降低的功率水平，并且可以通过回程网络或OTA发送。通过全部或部分地使用回程网络，即使对于由回程链接的半计划或无计划异构网络，也可以执行干扰避免。

摘要： Techniques for centralized control of peer discovery pilot transmission are described. In an aspect, a designated network entity (e.g., a base station or a network controller) may control transmission of peer discovery pilots by stations located within its coverage area. In one design, the network entity may receive signaling triggering peer discovery pilot transmission. The network entity may direct each of at least one station to transmit a peer discovery pilot to allow one or more stations to detect the at least one station. The peer discovery pilot may include at least one synchronization signal or at least one reference signal. The network entity may receive pilot measurements from the one or more stations for peer discovery pilots from peer stations and/or reference signals from base stations. The network entity may determine whether or not to select peer-to-peer communication for two stations based on the pilot measurements.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may receive a message sent by a second station to request reduction of interference on at least one resource. In response to receiving the message, the first station may determine a first transmit power level to use for the at least one resource based on one or more factors such as a priority metric sent in the message, the buffer size at the first station, etc. The first station may send a power decision pilot on the at least one resource at a second transmit power level determined based on the first transmit power level.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a serving base station may send a message to a terminal to trigger short-term interference mitigation. In response, the terminal may send a message to request at least one interfering base station to reduce interference on at least one resource. Each interfering base station may determine a transmit power level to be used for the at least one resource and may send a pilot at this transmit power level. The terminal may estimate the channel quality of the at least one resource based on at least one pilot received from the at least one interfering base station. The terminal may send information indicative of the estimated channel quality to the serving base station. The serving base station may send a data transmission on the at least one resource to the terminal.
