摘要： For restrictive reuse, each cell (or each sector) is assigned (1) a set of usable subbands that may be allocated to users in the cell and (2) a set of forbidden subbands that is not used. The usable and forbidden sets for each cell are orthogonal to one other. The usable set for each cell also overlaps the forbidden set for each neighboring cell. A user u in a cell x may be allocated subbands in the usable set for that cell. If user u observes/causes high level of interference from/to a neighboring cell y, then user u may be allocated subbands from a "restricted" set containing subbands included in both the usable set for cell x and the forbidden set for cell y. User u would then observe/cause no interference from/to cell y. The subband restriction may be extended to avoid interference from multiple neighboring cells.

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： 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 mitigating pilot pollution in a wireless network are described. In an aspect, pilot pollution may be mitigated by reducing density and/or transmit power of common pilots whenever possible. A cell may send a common pilot at a first density and a first transmit power level during a first time period and may send the common pilot at a second density and a second transmit power level during a second time period. The second density may be lower than the first density and/or the second transmit power level may be lower than the first transmit power level. Lower density may be achieved by sending the common pilot less frequently, on fewer subcarriers, and/or from fewer antennas. The cell may determine whether to reduce the density and/or transmit power of the common pilot based on network loading, SINRs of terminals, etc. In another aspect, pilot pollution may be mitigated by performing pilot cancellation at a terminal.
摘要翻译：描述了减轻无线网络中导频污染的技术。在一方面，可能通过尽可能减少公共飞行员的密度和/或发射功率来减轻飞行员污染。小区可以在第一时间段期间以第一密度和第一发射功率电平发送公共导频，并且可以在第二时间段期间以第二密度和第二发射功率电平发送公共导频。第二密度可以低于第一密度，和/或第二发射功率电平可能低于第一发射功率电平。较低的密度可以通过在较少的子载波上和/或从更少的天线较少频率地发送公共导频来实现。小区可以基于网络负载，终端的SINR等来确定是否降低公共导频的密度和/或发射功率。另一方面，可以通过在终端执行导频消除来减轻导频污染。

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： 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 serving sector directed transmit power control in a wireless communication environment. Under certain conditions, an access point can have better data with which to determine appropriate power levels than an individual terminal. Accordingly, an access point can transmit power control information to one or more terminals supported by the access point overriding normal power determination procedures. In particular, power control information can be included within an assignment message that designates resources (e.g., frequency, time) assigned to a terminal. Power control information can be based upon SNR, quality of service requirements, interference information, any other relevant information or any combination thereof.

摘要： Certain aspects of the present disclosure generally provide methods and apparatus for enhanced discovery procedures in peer-to-peer (P2P) wireless local area networks (WLANs). With these procedures, discovery duration may be decreased, battery power consumption may be reduced during discovery, provided services may be ascertained during the device discovery phase without performing a separate service discovery phase, and/or the discovery range may be extended in an effort to discover a greater number of devices.
