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： 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.

摘要： A network device may make a determination that a first backhaul connection, which serves a first base station, is congested and that a second backhaul connection, which serves a second base station, is not congested. This determination may be made based on a first periodic data cap imposed (on the first backhaul connection, a traffic load on the first backhaul connection, a second periodic data cap imposed on the second backhaul connection, and a traffic load on the second backhaul connection. In response to the determination, the network device may configure a value of a cellular communication parameter utilized by one or both of the base stations. The configuration may comprise periodic adjustments of the value of the cellular communication parameter. The periodic adjustments may cause one or more mobile devices to be cyclically handed-over between the first base station and the second base station.

摘要： Methods, devices and computer program products facilitate self-configuration and self-optimization of radio networks. An internal topology discovery is performed to assess characteristics of a plurality of access points within an internal network. An external cell discovery can also be performed to identify one or more access points operating within an external network. Based on the assessments obtained through the internal and/or external topology discovery processes, operational parameters are assigned to each access point within the internal network. Such operational parameters can include a transmit power associated with each radio node.

摘要： Group communications methods and apparatus are described. Multiple modes of group communications signaling are supported. In a first mode, copies of packets are separately transmitted to each group member in a sector or cell. In a second mode a copy of a packet is directed to multiple group members at the same time. Transitions between the two modes may be determined as a function of the cost of operating in each of the modes in terms of system cost and/or the number of group members in a cell or sector being serviced by a transmitter.

摘要： Methods of using superposition coding in a communications systems, e.g., a multi-user communications system. Superposition coding in accordance with the invention occurs in the case of an uplink by transmissions of different wireless terminals transmitting using the same communications resource, e.g., simultaneously transmitting using the same frequencies. The signals combine in the communications channel resulting in one transmission being superimposed on the other transmission. The device, e.g., base station, receiving the superimposed signals uses superposition decoding techniques to recover both signals. To obtain the benefit of the superposition, assignments of channel segments to multiple wireless terminals is controlled by the base station and/or transmission power levels are controlled by on or more wireless terminals sharing the same uplink communications resource, e.g., time slot, to make sure that the received signals from the different devices will have different received power levels making superposition decoding possible.

摘要： Embodiments describe mobility management utilizing neighbor discovery and at least two pseudo wires. When a wireless device desires to handoff to a detected access router, such handoff may not be configured until such time as a current access router receives routing information of the target access router. In order to minimize handoff time, communication between the target access router and the wireless device can be through the current access router utilizing least two pseudo wires. Bidirectional neighbor discovery and create is conducted by the access routers allow subsequent wireless devices to automatically handoff between the access routers.

摘要： Methods and apparatus for supporting and using multiple communications channels corresponding to different transmit technologies and/or access technologies in parallel within a cell of a wireless communications system are described. Mobile nodes support multiple technologies and can switch between the technology being used at a particular point in time, e.g., from a first channel corresponding to a first technology to a second channel corresponding to a different technology which provides better transmission characteristics, e.g., a better perceived channel quality. Mobiles maintain at least two sets of channel quality information at any one point in time. Mobiles select the better channel and communicate the channel selection to the base station or communicate channel quality information for multiple channels to the basestation and allow the base station to select the channel corresponding to the technology providing the better conditions for the mobile. Different mobiles in the same cell may support different technologies.
