    Abstract: 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.

    Abstract: 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.

    Abstract: Methods and apparatus for using end nodes, e.g., wireless terminals, to discover base stations and communicate information about discovered access nodes, e.g., base stations, to other access nodes in a system are described. As the wireless terminal roams in the system and new access nodes are encountered, one or more physically adjacent access nodes will be informed of the presence of the new access node as a result of communications with the wireless terminal. A message indicating an access node's inability to route a message to another access node which is known to a wireless terminal may trigger the wireless terminal to begin the process of updating access node routing and neighbor information.

    IPC: H04L27/26

    Abstract: A composite signal includes a high power beacon signal and low power corresponding wideband synchronization signal and is communicated over a time interval exceeding a single OFDM transmission time interval. A base station transmits one or more different such composite broadcast signals in a recurring timing structure. Each different potential beacon signal, e.g., a single tone signal, is paired with a unique wideband synchronization signal. A wideband synchronization signal includes at least some predetermined null tones and at least some predetermined non-null tones. For a given wideband synchronization signal, the predetermined null tones carry predetermined modulation symbol values, A wireless terminal receives a composite signal, identifies a beacon, determines a corresponding known wideband synchronization signal, compares received to known wideband synchronization signals, and determines at least one of a timing adjustment, frequency adjustment and channel estimation.

    Abstract: Systems and methodologies are described that facilitate assigning a flow (e.g., IP flow) to a wireless network link from a bundle that includes a plurality of wireless network links. Assignments can be based upon characteristics associated with the flow and characteristics associated with the links. For example, a service class corresponding to the flow can be evaluated to determine flow related characteristics. Moreover, link related feedback can be analyzed to determine characteristics of the links.

    Abstract: Un procedimiento para ajustar la temporización de símbolos en un primer dispositivo de comunicaciones en un sistema Ortogonal Multiplexador por División de Frecuencia (OFDM), comprendiendo el procedimiento: - determinar que se haga un ajuste de temporización de símbolos del receptor, a fin de ajustar la temporización de símbolos del receptor en dicho primer dispositivo de comunicaciones, para sincronizar la temporización de símbolos del receptor con la temporización de símbolos de un segundo dispositivo de comunicaciones; caracterizado por - ajustar la temporización de símbolos de un transmisor en dicho primer dispositivo de comunicaciones como una función de dicho determinado ajuste de temporización de símbolos del receptor; y - dicha etapa de ajuste de temporización de símbolos del transmisor incluye la selección de uno entre un primer y un último símbolo en un lapso a modificar para ajustar la temporización de símbolos del transmisor, siendo dicho lapso un periodo de tiempo durante el cual dicho transmisor mantiene el mismo tono, o un periodo de tiempo que comprende múltiples tiempos de símbolos antes de conmutar a otro tono o grupo de tonos.
