    摘要: Systems and methodologies are described that provide techniques for generating and utilizing reverse link feedback for interference management in a wireless communication system. Channel quality and/or interference data can be obtained by a terminal from a serving sector and one or more neighboring sectors, from which an interference-based headroom value can be computed that contains interference caused by the terminal to an allowable range. The interference-based headroom value can then be provided with power amplifier (PA) headroom feedback to the serving sector. Based on the provided feedback from the terminal, the serving sector can assign resources for use by the terminal in communication with the serving sector. Further, the serving sector may choose to honor or disregard a received interference-based power value based on quality of service and/or other system parameters.

    摘要: Techniques for selecting a serving base station for a terminal in a wireless communication network are described. In one design, multiple candidate base stations for the terminal may be identified, with each candidate base station being a candidate for selection as the serving base station for the terminal. The multiple candidate base stations may include base stations with different transmit power levels and/or may support interference mitigation. One of the multiple candidate base stations may be selected as the serving base station. In one design, the serving base station may be selected based on at least one metric for each candidate base station. The at least one metrics may be for pathloss, effective transmit power, effective geometry, projected data rate, control channel reliability, network utility, etc. The selected candidate base station may have a lower SINR than a highest SINR among the multiple candidate base stations.

    摘要: Methods and apparatuses are provided that facilitate associating with relays in a wireless network. A device can select whether to utilize relay assistance where present based at least in part on measuring one or more determined or projected parameters related to the relay. Where utilizing a relay results in user-plane data channel conditions above a threshold level and control channel conditions below a threshold level, a serving base station can determine whether to employ another base station to serve the device, jointly serve a relay with an additional base station, and/or the like.

    摘要: Techniques for scheduling UEs are described. In one design, a scheduler (e.g., for a cell) may receive channel direction information (CDI) and channel strength information (CSI) from a plurality of UEs. In one design, the CDI from each UE may include at least one eigenvector, and the CSI from each UE may include at least one singular value corresponding to the at least one eigenvector. The scheduler may schedule at least one UE among the plurality of UEs for data transmission based on the CDI and CSI from the plurality of UEs. The scheduler may select the at least one UE based on a metric related to signal-to-leakage ratio (SLR), or spectral efficiency, etc. In one design, the scheduler may evaluate the performance of different sets of UEs to determine whether to schedule one UE for single-user MIMO or multiple UEs for multi-user MIMO.

    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.
