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 transmission, upon an uplink traffic channel in Orthogonal Frequency Division Multiplexing (OFDM) environments. Uplink scheduling may include user selection and rate selection. Further, user selection may be based on a token mechanism that provides control over fairness of allocation to disparate users. Moreover, rate selection may be based upon considerations of uplink interference mitigation.

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).

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 multi-mode base station includes a transmit standby mode and an active mode. Transmit standby mode of base station operation is a low power/low interference level of operation as compared to active mode. In transmit standby mode at least some of the synchronization signaling such as pilot tone signaling is reduced in power level and/or rate with respect to the active mode. In transmit standby mode, the base station has no active state registered wireless terminals being serviced but may have some sleep state registered wireless terminals being serviced. Mode transitions from active to transmit standby may be in response to: a detected period of inactivity, scheduling information, base station mode change signals, and/or detected wireless terminal state transition. Mode transitions from transmit standby to active may be in response to: scheduling information, access signals, wake-up signals, hand-off signals, wireless terminal state change signals, and/or base station mode change signals.

摘要： Techniques for efficiently sending reports in a wireless communication system are described. Reports may be sent repetitively in accordance with a reporting format. A terminal receives an assignment of a control channel used to send reports and determines a reporting format to use based on the assignment. The reporting format indicates a specific sequence of reports sent in specific locations of a control channel frame. The terminal generates a set of reports for each reporting interval and arranges the set of reports in accordance with the reporting format. The terminal repetitively sends a plurality of sets of reports in a plurality of reporting intervals. Reports may also be sent adaptively based on operating conditions. An appropriate reporting format may be selected based on the operating conditions of the terminal, which may be characterized by environment (e.g., mobility), capabilities, QoS, and/or other factors.

摘要： Methods and apparatus for communicating transmission backlog information are described. Reporting control factors are utilized to expand reporting possibilities for a fixed bit size request report. At least one report control factor is determined as a function of channel quality information, power information, device capability information, and/or quality of service information. A transmission backlog report value is interpreted as a function of a reporting control factor. A wide range of quantization schemes for reporting transmission backlog information are facilitated corresponding to a small bit size report. A communications device can adaptively select a quantization request level closely matched to its current needs such as to provide an accurate representation of its current traffic channel resource needs. A communications device may request a number of frames in a request report and the same report may be indirectly requesting a number of communications segments needed to clear its transmission backlog.
