PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate utilizing different power control algorithms as a function of access terminal speed.SOLUTION: Instantaneous channel quality indicator (CQI) reports can be inverted for slow moving access terminals while long-term geometry inversion (e.g., average CQI report inversion) can be utilized for quick moving access terminals. Speed of the access terminal can be estimated upon the basis of time correlation of CQI values. Further, selection of implementing instantaneous CQI inversion or long-term geometry inversion can be based upon the estimated speed of the access terminal.

PROBLEM TO BE SOLVED: To provide a method and an apparatus of wireless communications, more specifically, a method and an apparatus for implementing a dedicated control channel and using the dedicated control channel.SOLUTION: Wireless terminals and base stations support multiple modes of dedicated control channel operation, where different amounts of dedicated uplink resources for reporting control information are allocated to the wireless terminals. A set of dedicated control channel segments is utilized by the wireless terminals to communicate uplink control information reports to serving base station attachment points. Full tone and split-tone modes of dedicated control channel operation are supported. In the full tone mode, each of the dedicated control channel segments associated with a single logical tone is allocated to a single wireless terminal. In the split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals.

PROBLEM TO BE SOLVED: To support a plurality of report dictionaries, e.g., uplink transmission backlog request report dictionaries, in a wireless communications system.SOLUTION: Each report dictionary provides bit mapping definition information corresponding to a set of fixed bit size request reports. Different report dictionaries are structured to accommodate different reporting conditions, needs, and/or requirements. A communications device selects a report dictionary, e.g., on a per connection basis, to be used in communicating transmission backlog information, from among the plurality of possible report dictionaries. Information characterizing active traffic flows such as the number of distinct quality of service profiles and/or the current mixture of best effort and latency constrained traffic flows is used in performing the selection of a report dictionary. The selected report dictionary is subsequently utilized to generate reports and interpret information communicated in those generated reports.

PROBLEM TO BE SOLVED: To provide a multi-mode base station having a transmission standby mode that is a low power/low interference level of operation.SOLUTION: A multi-mode base station includes a transmission standby mode and an active mode. Transmission standby mode (1322) of base station operation is a low power/low interference level of operation as compared to active mode. In transmission 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 the transmission standby mode, the base station may have some sleep state registered wireless terminals being serviced. Mode transitions (1320) from active to transmission 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 transmission 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.

Further, power to be used by transmitters can be assigned as a function of time. Moreover, a single sub-carrier network and/or a multiple sub-carrier network can utilize one or more power allocation schemes.

Additionally, the multiple connections may be evaluated and a preferred connection among the set of multiple connections may be utilized to transfer data to the wireless terminal over a downlink connection.

PROBLEM TO BE SOLVED: To provide methods related to communications device control information reporting.SOLUTION: An initial reporting structure for an uplink dedicated control channel is used by a wireless terminal following a transition into a state of wireless terminal operation or action which makes it desirable to provide a base station with an initial set of control information which can be used to support uplink transmission of user data. Subsequently, while continuing operation in a state supporting uplink transmission of user data, a recurring scheduled reporting structure for the uplink dedicated control channel is followed by the wireless terminal. The initial reporting structure provides communication of at least some information reports, e.g., infrequently scheduled reports which may not be otherwise communicated during the same time interval if the recurring scheduled reporting structure is not overridden.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for communicating transmission backlog information.SOLUTION: Reporting control factors are utilized to expand reporting possibilities for a fixed bit size request report. The 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 adaptively selects 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 the number of frames in a request report, and the same report may indirectly request the number of communications segments needed to clear its transmission backlog.
