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： 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 send a first message to at least one interfering station to request reduction of interference on at least one resource. The first station may send the first message in anticipation of receiving data on the at least one resource. An interfering station may receive the first message from the first station and may reduce interference on the at least one resource by reducing its transmit power and/or by steering its power in a direction different from the first station. The first station may thereafter receive data from a second station on the at least one resource. The techniques may be used for data transmission on the forward and reverse links.

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： Methods, systems, apparatus and computer program products are provided to facilitate power control in wireless communication systems. A cell that is experiencing excessive interference conditions may generate an over-the-air overload indicator indicative of interference conditions at the cell. The over-the-air overload indicator is received by one or more user equipment in a neighboring cell. In response, the user equipment determines adjustments to its transmit power that reduce and/or eliminate the interference. This determination may be carried out by the user equipment, by the serving base station, or through cooperation between the user equipment and the serving base station. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.

摘要： Providing for record filtering in distributed dynamic clustering algorithms for coordinated multipoint (CoMP) wireless communication is described herein. By way of example, strategy selection records distributed as part of a belief propagation network are pruned at recipient nodes, thereby reducing processing overhead for dynamic clustering. As a result, cooperative policies can be determined with greater efficiency, and with greater relevance to local clusters of cooperating base stations. In some aspects, record pruning can comprise identifying and discarding redundant or incompatible sets of policy decisions. In at least one aspect, a number of evaluated records can be capped based on relevance, while preserving deployment-wide applicability of the belief propagation network. Accordingly, dynamic distributed CoMP decisions are optimized on a deployment-wide scale that more efficiently converges to maximum utility solutions.

摘要： Techniques for performing association with leakage-based metrics in a wireless network are described. Association may be performed to select a serving node (e.g., a base station or a relay) for a station (e.g., a UE or a relay). In one design, at least one metric may be determined for at least one candidate node for possible association by the station. A metric for each candidate node may be determined based on leakage of the candidate node. The leakage of the candidate node may include interference due to the candidate node at stations not served by the candidate node (excluding the station). The metric for each candidate node may include a signal-to-leakage ratio (SLR), a geometry-to-leakage ratio (GLR), or a throughput-to-leakage ratio (TLR). A serving node for the station may be selected from among the at least one candidate node based on the at least one metric.

摘要： Techniques for performing association and resource partitioning in a wireless network with relays are described. In an aspect, resource partitioning may be performed to allocate available resources to nodes and access/backhaul links of relays. In one design, a node computes local metrics for a plurality of possible actions related to resource partitioning. The node receives local metrics for the possible actions from at least one neighbor node and determines overall metrics for the possible actions based on the computed and received local metrics. The node determines resources allocated to a set of nodes and resources allocated to the access and backhaul links of at least one relay based on the overall metrics for the possible actions. In another aspect, association involving relays may be performed by taking into account the performance of the relays. In yet another aspect, association and resource partitioning may be performed jointly.
