摘要： A wireless communications system supports wireless connections between base station sector attachment points and wireless terminals. Individual wireless connections correspond to one of a downlink-macrodiversity mode of operation and a downlink non-macrodiversity mode of operation. A wireless terminal has, for each of its current connections, a base station assigned dedicated control channel for communicating uplink control information reports. The uplink control information reports include downlink signal-to-noise ratio reports based on measured received pilot channel signals. If a connection corresponds to a macrodiversity mode of operation, a reporting format for the SNR report is used which reports (i) an SNR value and (ii) an indication as to whether or not the connection is considered a preferred connection by the wireless terminal. If a connection corresponds to a non-macrodiversity mode of operation, a reporting format for the SNR report is used which reports an SNR value.

摘要： An access node, e.g., base station, determines a configuration of an end node, e.g., wireless terminal, intended to support a specific traffic flow and sends a configuration command to the wireless terminal. A base station may determine one or more parameters associated with classification, queue management, scheduling, and/or automatic repeat request, and then send a configuration command to the wireless terminal instructing it to implement a configuration operation. In some embodiments, a wireless terminal sets the value of an internal parameter to a value directly provided by the base station in a configuration command. In some embodiments, a wireless terminal determines and sets the value of an internal parameter as a function of information included in the configuration command from the base station.

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： 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： Wireless terminals and base stations support multiple modes of dedicated control channel operation wherein wireless terminals are allocated different amounts of dedicated uplink resources for reporting control information. A set of dedicated control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of dedicated control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the dedicated control channel segments associated with a single logical tone. In split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the dedicated control channel segments. Logical dedicated control channel tones can be dynamically reallocated for full-tone mode use or split tone mode use.
