    摘要: 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.

    摘要: Symbol timing synchronization in OFDM communication systems where multiple wireless terminals communicate with a single base station is described. Base station transmitter and receiver symbol timing is fixed. Each wireless terminal operates to independently adjust its transmitter timing. Transmitter timing synchronization at the wireless terminal is slaved to the terminal's receiver timing synchronization. Each wireless terminal first corrects its receiver symbol timing based on a signal received from the base station. The wireless terminal then adjusts its transmitter symbol timing as a function of its receiver symbol timing. When the receiver symbol timing is to be advanced or delayed by some amount, the transmitter symbol timing is also advanced or delayed, respectively, by the same, or substantially the same, amount. Symbol timing adjustment can be made by adding or deleting digital samples from the first or last symbol in a dwell.

    摘要: Methods and apparatus of efficient communication of resource allocation are described. A base station transmits a resource assignment message, e.g., a state transition message, to a wireless terminal including a first part, e.g., a base station assigned wireless terminal On state identifier, identifying a resource being assigned and a second part, e.g., an ON state mask, identifying a portion of the resource allocated to the wireless terminal. The same resource allocation message information also communicates one of a plurality of different modes of commanded On state operation. The resource allocation message structure supports flexible allocation of available resources facilitating a resource to be partitioned differently at different times accommodating current needs. A predetermined recurring channel structure and association of segments with particular mask bits, facilitates allocated control segments to be used unambiguously without the need to include an overhead wireless terminal identifier field with the control report bits being communicated.

    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.

    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: Improved beacon signaling methods are described. Beacon signals are transmitted on the same tone in at least two consecutive symbol periods facilitating accurate energy measurements over a symbol period even if timing synchronization with the transmitter is not maintained. A low power wideband signal is also combined with the beacon signal to facilitate channel estimation and other operations such as timing synchronization operations.
