摘要： A base station uses a common link layer controller for multiple physical attachment points to facilitate concurrent wireless connections between different sector physical attachment points and a wireless terminal using the same link layer link. A wireless terminal maintains multiple simultaneous wireless connections for the same link layer link. A packet of user data is fragmented into a plurality of grouping of MAC frames, thus a packet portion can be communicated over a connection. A single packet is sometimes communicated with different portions conveyed over different wireless connections. Automatic repeat request, using the common link layer controller, allows for retransmission of a packet portion over a different connection than it was initially transmitted over. A wireless terminal sends connection request messages including lists of link layer identifiers associated with the wireless terminal. A base station responds with an indication of whether logical link state was already present.

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 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： 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： Wireless terminal for use with a multi-mode base station that supports a transmit standby mode and an active mode is described. 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 from the wireless terminal, hand-off signals, etc.

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.
