  • Publication number: 20070147424
    Abstract: A base station uses a common link layer controller corresponding to multiple physical attachment points, facilitating multiple concurrent wireless connections between different base station sector physical attachment points and the same 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, implemented 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.

  • Publication number: 20070149129
    Abstract: 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.

  • Publication number: 20070149131
    Abstract: Methods and apparatus related to control information reporting over wireless communication channels are described. Various embodiments include communicating control information format definition information over a wireless link. For example, in some embodiments, a base station downloads control information reporting format definition information, e.g., corresponding to a new release or a custom reporting format, into a wireless terminal. As another example, a wireless terminal generates a custom control information reporting format, that it intends to use, and communicates definition information corresponding to the generated custom control reporting format to a base station.

  • Publication number: 20070149132
    Abstract: Methods and apparatus related to the implementation and selection of alterative control information reporting formats are described. A control information reporting format, corresponding to a connection between a wireless terminal and a base station, e.g., for an uplink dedicated control channel, is selected, as a function of at least one of: an application being executed, device capability information, channel condition information, system loading information, and user quality of service information. Different wireless terminals may use different control information reporting formats at the same time. The same wireless terminal may use a different control information reporting format at different times.

  • Publication number: 20070149128
    Abstract: 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.

  • Publication number: 20070147377
    Abstract: Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.

  • Publication number: 20070142048
    Abstract: Methods and apparatus for indicating parameter change points with respect to multiple connections (wireless links) by transmitting a single message, e.g., over one of the connections, is described. A base station corresponding to at least one connection, considers the approximate timing relationship between the connections, selects one of the connections, selects an intended parameter switching point for that connection, determines a symbol time offset from the selected switching point such that the other intended switching points of other wireless links can be unambiguously interpreted by the wireless terminal from information indicating the offset with respect to the selected link, and communicates information indicating the offset and the wireless link to which said offset applies. A wireless terminal receives the information, identifies a time referenced with respect the timing structure of the identified wireless link and then determines individual parameter switching points for the other wireless links.

  • Publication number: 20070083669
    Abstract: Embodiments describe synchronizing access routers with wireless terminal state information. According to an embodiment is a wireless terminal that transmits a message that includes an address for at least two access routers. State change information can optionally be included in the message. According to another embodiment is an access router that receives a state change notification from a wireless device or another access router. The state change notification is updated in the access router. An acknowledgment confirming the updated state change may be sent to the wireless terminal. Dynamic state synchronization is provided with minimal communication with wireless terminal.

  • Publication number: 20070066329
    Abstract: 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.
