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.

摘要： Systems and methodologies are described that facilitate assigning carriers to access points based on power class. Devices can accordingly evaluate cells provided by the access points to select a cell with an optimal SNR or path loss for communication regardless of power class, since lower powered cells will not be interfered by higher powered cells communicating over different carriers. Cross-carrier operation is also provided where access points can transmit downlink signals according to carrier assignment information while receiving uplink signals over other carriers. Thus, once an optimal cell is determined, downlink control data can be received over the assigned carrier to ensure receipt without interference, but uplink transmissions can occur over multiple carriers to facilitate increased throughput using one or more reuse schemes.
摘要翻译：描述了有助于基于功率等级将载波分配给接入点的系统和方法。因此，无论功率等级如何，设备可以相应地评估由接入点提供的小区以选择具有最佳SNR或通信路径损耗的小区，因为低功率小区不会受到通过不同载波通信的较高功率小区的干扰。还提供跨载波操作，其中接入点可以根据载波分配信息发送下行链路信号，同时在其他载波上接收上行链路信号。因此，一旦确定了最佳小区，就可以通过分配的载波接收下行链路控制数据，以确保无干扰地接收，但是上行链路传输可以在多个载波上发生，以便利用一个或多个重用方案来提高吞吐量。

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： Techniques for allocating and mapping resources in a wireless communication system are described. The system may use hop-ports to facilitate allocation and use of subcarriers. In one aspect, the hop-ports may be partitioned into multiple subzones, with each subzone including a configurable number of hop-ports. The hop-ports within each subzone may be permuted or shuffled based on a permutation function. After permutation, the hop-ports in all subzones may be mapped to the subcarriers based on local or global hopping. In another aspect, a set of hop-ports may be mapped to a set of subcarriers. A hop-port may be mapped to an unavailable subcarrier and may then be remapped to another available subcarrier. In yet another aspect, a set of hop-ports may be mapped to a set of subcarriers distributed (e.g., evenly) across all subcarriers but avoiding subcarriers in a reserved zone.

摘要： Systems and methodologies are described that facilitates communicating Physical Control Format Indicator Channel (PCFICH) information to a user equipment (UE) in which the PCFICH information is specific to a particular component carrier. The PCFICH information for each component carrier can be communicated via an anchor component carrier in order to reduce decoding each PCFICH information for each component carrier. In particular, the PCFICH information can be decoded for an anchor component carrier and PCFICH information for additional carriers can be included in a Multi-Carrier (MC) grant of the Physical Downlink Control Channel (PDCCH).

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.
