摘要： Providing fairness-based metrics for managing inter-sector interference of a mobile AN is described herein. By way of example, accumulation of resource utilization messages (RUMs) at a sector of the mobile AN can be based at least in part on a performance metric of that sector as compared with one or more neighboring sectors. In at least one aspect, performance metrics of multiple sectors of the mobile AN can be aggregated and a RUM accumulation rate of each sector is determined based on the aggregated metric. Accumulation rates can further be updated periodically as sector and/or aggregated metrics of the mobile AN change. Accordingly, accumulation and utilization of RUMs is based on inter-sector fairness to optimize overall wireless communication quality of service for the mobile AN.

摘要： Providing for management of wireless communications in a heterogeneous wireless access point (AP) environment is described herein. By way of example, system data of an over-the-air message can be configured to include information identifying a distinct type of transmitting base station. In some aspects, the information can include an access type of the base station and/or a sector ID for distinguishing the base station among large numbers of other base stations. According to other aspects, the information can include wireless channel resources designated for a particular type of base station, or blanked by the transmitting base station, to facilitate interference reduction on such resources. By employing aspects of wireless communication management disclosed herein, efficient and reliable communication can be affected in large heterogeneous AP networks.

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 provide techniques for performing adjustments for delta-based power control and interference management in a wireless communication system. A terminal can utilize one or more delta-based power control techniques described herein upon engaging in a reverse link transmission after a predetermined period of silence or after receiving indications of interference from neighboring access points. A delta value can be computed through open-loop projection, based on which transmission resources such as bandwidth and/or transmit power can be increased or decreased to manage interference caused by the terminal. A delta value, other feedback from the terminal, and/or indications of interference caused by the terminal can also be communicated as feedback to a serving access point to allow the access point to assign transmission resources for the terminal.

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： 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.
