    摘要: For interference control, a sector m estimates interference observed from terminals in neighbor sectors and obtains an interference estimate. Sector m may generate an over-the-air (OTA) other-sector interference (OSI) report and/or an inter-sector (IS) OSI report based on the interference estimate. Sector m may broadcast the OTA OSI report to the terminals in the neighbor sectors. These terminals may adjust their transmit powers based on the OTA OSI report. Sector m may send the IS OSI report to the neighbor sectors, receive IS OSI reports from the neighbor sectors, and regulate data transmissions for terminals in sector m based on the received IS OSI reports. Sector m may control admission of terminals to sector m, de-assign admitted terminals, schedule terminals in sector m in a manner to reduce interference to the neighbor sectors, and/or assign the terminals in sector m with traffic channels that cause less interference to the neighbor sectors.

    摘要: Systems and methodologies are described that facilitate efficiently providing scheduling information from an access terminal to a base station to enable effectuating scheduling decisions. Access terminals may transmit scheduling information in bifurcated requests. For instance, coarse scheduling information may be transferred utilizing a dedicated out-of-band channel, and fine scheduling information may be transmitted over an in-band channel.

    摘要: Techniques for adjusting transmit power to mitigate both intra-sector interference to a serving base station and inter-sector interference to neighbor base stations are described. The amount of inter-sector interference that a terminal may cause may be roughly estimated based on the total interference observed by each neighbor base station, channel gains for the serving and neighbor base stations, and the current transmit power level. The transmit power may be decreased if high interference is observed by a neighbor base station and increased otherwise. The transmit power may be adjusted by a larger amount and/or more frequently if the terminal is located closer to the neighbor base station observing high interference and/or if the current transmit power level is higher, and vice versa. The intra-sector interference is maintained within an acceptable level by limiting a received SNR for the terminal to be within a range of allowable SNRs.

    摘要: Systems and methodologies are described that facilitate scheduling via a power control algorithm that dynamically update a scheduling metric (e.g., adjusting transmission power for sub-carriers) based on a prediction function and/or inference model of expected power requirements. In one aspect, the power prediction component can include two further components, namely: the data channel component and the control channel component—wherein a carrier to interference ratio (C/I) information is being transmitted on such control channel and the power is adjusted to obtain performance requirements. Accordingly, an efficient scheduling of users on a reverse link in an orthogonal manner can be provided, to optimally use system resources, while simultaneously: maintaining a predetermined and/or arbitrary fairness metrics, maintaining quality of service and maximizing throughput.
