    • A method and system for communicating header compression layer control messages. Header compression control messages are generated by a header compression layer (302) and are sent through at least one link layer data packet by a link transport communications protocol layer (304) to a remote receiver (104). The link transport communications protocol layer (304) monitors receipt of link layer data packet acknowledgements that are received from the link transport communications protocol layer (304) of the remote receiver (104) for the at least one link layer data packet. The link transport communications protocol layer (304) determines successful transmission of the header compression control message and provides, to the header compression layer (302), an indication of successful header compression control message transmission.

    • A communication system provides secure communication between two nodes in a self-organizing network without the need for a centralized security or control device. A first node of the two nodes is provisioned with one or more security profiles, auto-discovers a second node of the two nodes, authenticates the second node based on a security profile of the one or more security profiles, selects a security profile of the one or more security profiles to encrypt a communication session between the two nodes, and encrypts the communication session between the two nodes based on the selected security profile. The second node also is provisioned with the same one or more security profiles, authenticates the first node based on a same security profile as is used to authenticate the second node, and encrypts the communication session based on the same security profile as is used for encryption by the first node.

    • Communication devices and methods for transmitting and receiving a wideband signal using aggregated discontiguous narrowband channels in a band are presented. During transmission, a fold point is determined in which symmetric free channels are sufficient to transmit the signal. The signal is then synthesized by aggregating the data in the channels and transmitted using the fold point as the up-conversion modulation frequency. During reception, information regarding which channels are being used to provide data signals and which channels are occupied by interferers is received. This information is used to determine one or more fold points as the down-conversion modulation frequencies. The fold points are selected such that an image of each interferer falls on an unoccupied channel or a narrowband channel occupied by another interferer.
