摘要： Systems and methodologies are described that facilitate utilizing power-based rate signaling for uplink scheduling in a wireless communications system. A maximum nominal power (e.g., relative maximum transmit power that may be employed on an uplink) may be known to both a base station and a mobile device. For example, the base station and the mobile device may agree upon a maximum nominal power. According to another example, signaling related to a maximum nominal power for utilization on the uplink may be provided over a downlink. Further, selection of a code rate, modulation scheme, and the like for the uplink may be effectuated by a mobile device as a function of the maximum nominal power. Moreover, such selection may be based at least in part upon an interference cost, which may be evaluated by the mobile device.

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.

摘要： A wireless terminal determines the transmission power used for its dedicated control channel at a point in time, and generates a power report indicating a ratio of a maximum wireless terminal transmit power to the transmit power of the dedicated control channel at the point in time. The power report provides a measure of available transmit power for wireless terminal use for other purposes, e.g., uplink traffic channels, after taking into consideration the transmit power used for the dedicated control channel. The point in time has a known time offset from the start of a communications segment in which the power report is transmitted. This allows the base station receiving dedicated control channel uplink signals from the wireless terminal to measure the received signals, receive and process the communicated power report, and correlate information to be used for accurate wireless terminal closed loop power control.

摘要： A wireless terminal receives and measures broadcast reference signals, e.g., beacon and/or pilot signals, transmitted from a plurality of base station attachment points. The wireless terminal monitors for and attempts to recover broadcast loading factor information corresponding to attachment points. The wireless terminal generates and transmits an interference report to a current attachment point, the report based on the results of a measured received reference signal from the current attachment point, a measured received reference signal from each of one or more different attachment points, and uplink loading factor information. In the absence of a successfully recovered broadcast uplink loading factor corresponding to an attachment point, the wireless terminal uses a default value for that loading factor. Generated interference reports are based on beacon signal measurements and uplink loading factors, pilot signal measurements and uplink loading factors, or a mixture of beacon and pilot signal measurements and uplink loading factors.

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： 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).
