摘要： Methods and apparatus for efficient communication of backlog information, e.g., backlog information indicating amounts of uplink traffic waiting to transmitted by a wireless terminal are described. Delta backlog reports are used in addition to absolute backlog reports, thus reducing control signaling overhead, at least some information communicated in a delta backlog report being referenced with respect to a previously transmitted backlog report. A base station uses received backlog information from wireless terminals in determining scheduling of uplink traffic channel segments In some embodiments, the absolute backlog report uses a first fixed size report format, while the delta backlog report using a second fixed size report format, said second size being different from said first fixed size.

摘要： Power control reports are communicated less frequently than the power control commands. The base station tracks the commands sent to the wireless terminal and estimates the wireless terminal's control channel transmit power. Received power control channel reports are utilized to compare the base station's estimated wireless terminal control channel transmit power to the actual wireless terminal control channel transmit power. An estimate of the error rate of transmitted power control signals is generated based using the tracked power command information and received power report information. Adjustments are performed in the power control command signaling to compensate for estimated error rates.

摘要： A wireless terminal receives a broadcast uplink interference report request conveying a requested report type and/or a locally unique base station identifier. The wireless terminal receives and measures broadcast reference signals, e.g., beacon and/or pilot signals, transmitted from a plurality of base station attachment points. Specific type interference reports relate a current serving connection base station attachment point to a selected base station attachment point corresponding to the received base station identifier. Generic type interference reports relate a current serving base station connection attachment point to other unspecified base station attachment points whose broadcast reference signals have been detected by the wireless terminal. Sub-types of generic reports include summation function and maximum function reports. Timing information is sometimes used to determine report sub-type and/or sector type of the selected attachment point. The wireless terminal generates the requested report and transmits it to the current connection attachment point.

摘要： Systems and methodologies are described that facilitate scheduling uplink transmissions. For instance, a time sharing scheme can be utilized such that differing mobile devices can be scheduled to transmit during differing time slots; however, it is also contemplated that a static scheme can be employed. Pursuant to an illustration, an interference budget can be combined with a time varying weighting factor associated with a base station; the weighting factor can be predefined and/or adaptively adjusted (e.g., based upon a load balancing mechanism). Moreover, the weighted interference budget can be leveraged for selecting mobile devices for uplink transmission (e.g., based at least in part upon path loss ratios of the mobile devices). Further, disparate interference budgets can be utilized by differing channels of a sector at a particular time. Also, for example, a base station can assign a loading factor to be utilized by wireless terminal(s) for generating channel quality report(s).
