    Abstract: A method, an apparatus, and a computer program product for sustaining a link with a wireless network are provided. The apparatus communicates data with the wireless network via a first link with a first base station, acquires a resource to perform a beam training sequence with a second base station, wherein the acquired resource allows the beam training sequence with the second base station to be performed while the data is communicated via the first link, performs the beam training sequence and exchanging signaling information with the second base station using the resource to establish a second link to the second base station, evaluates a link strength of the second link based on the beam training sequence, and determines whether to switch the data communication from the first link to the second link based on the evaluation.

    Abstract: FDM signal communication methods and apparatus are described. In accordance with the invention FDM signals are generated in the time domain with symbols being mapped to specific point in time. Training symbols may be included in the transmitted FDM signal to facilitate symbol recovery. An exemplary receiver receives the FDM signal from the communications channel, converts it into the frequency domain, and then filters it in the frequency domain to eliminate tones corresponding to other users. The filtered signal free of MAC interference is then converted into the time domain where channel estimation and compensation operations are performed. After channel compensation symbol recovery is performed in the time domain

    Abstract: In a first configuration, the apparatus may be a base station. The base station adjusts a periodicity for performing a beam sweep, sends information indicating the adjusted periodicity for performing a beam sweep, and performs the beam sweep at the adjusted periodicity. In a second configuration, the apparatus may be a UE. The UE receives information indicating a periodicity for performing a beam sweep from a base station, adjusts the periodicity for performing the beam sweep, and performs the beam sweep at the adjusted periodicity. For both configurations, the beam sweep is a plurality of transmissions of a beam in a plurality of different transmit spatial directions by one of the base station or the UE and a plurality of scans of the beam transmissions in a plurality of different scan spatial directions by an other of the one of the base station or the UE.

    Abstract: 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

    Abstract: Methods and apparatus for wireless communications in regional networks, e.g., ad hoc peer to peer networks, are described. Wireless communications devices transmit and monitor for presence indicator signals broadcast from other peer communications devices in its local vicinity. A wireless communications device maintains a list of discovered devices in its vicinity. A first wireless communications device transmits a paging signal directly over an airlink to a second communications device, which is on its list and to which it desires to send data units, e.g., user data in a peer to peer traffic segment. In response to a received paging response signal from the second device, the first device transmits data units, intended for the second device, to a third device, which acts as an intermediary node. The power level for the data unit signal is controlled to be lower than the power level used for the paging signal.
