Abstract: A solution for operating a radio communication apparatus exchanges narrowband control messages with other radio communication apparatuses, each control message comprising a pilot sequence and an identifier identifying a transmitter of the control message. The radio communication apparatus receives a broadband signal through a broadband radio receiver and correlates sub-bands of the received signal so as to detect a narrowband control message within the received broadband signal. Upon detection of the narrowband control message on a sub-band of the received broadband signal, the transmitter of the narrowband control message is determined from the identifier of the narrowband control message. It is also determined from the reception of the narrowband control message on the sub-band that the sub-band is preferred by the transmitter of the narrowband control message, and said sub-band is utilized in data communication with the transmitter of the narrowband control message.

Abstract: A solution for operating a radio communication apparatus communicating with at least one other apparatus is provided. In communication, a frequency block of a set of frequency blocks having a given center frequency is utilized. The center frequencies of at least some adjacent frequency blocks are separated by a given frequency offset. The offset is selected such that the adjacent frequency blocks are partly overlapping and the apparatus receiving a given frequency interprets a signal separated from the given signal by the offset as noise.

Abstract: A method and an apparatus for bundling data packet acknowledgments in a wireless communication device is disclosed. The method includes determining a metric proportional to a communication distance between the wireless communication device and a counterpart wireless communication device; selecting a number of data packet acknowledgments to be bundled together according to the determined communication distance such that when the communication distance is higher, the higher number of data packet acknowledgments are bundled together into a single acknowledgment message; and causing transmission of the acknowledgment message comprising the selected number of data packet acknowledgments.

Abstract: A communication system is provided. The system comprises a server arrangement; a plurality of mobile base stations coupled in communication with the server arrangement; and a plurality of mobile stations. A given mobile station from amongst the plurality of mobile stations is capable of communicating with two or more of the plurality of mobile base stations using radio communications. The server arrangement is operable to select, from amongst the two or more of the plurality of mobile base stations, a mobile base station to be used to route data to and/or from the given mobile station.

Abstract: A method of operating a radio station is provided. One or more capability announcement messages are received from one or more other radio stations. The one or more capability announcement messages are analyzed to gather analyzed communication-capability information indicative of the one or more other radio stations that are available for communication and respective communication capabilities of the one or more other radio stations. Subsequently, a station map, maintained locally at the radio station, is updated with the communication-capability information. The station map is then used to select a target radio station for accessing a communication network.

Abstract: A radio network uses two sequences to identify a receiver of a message. The receiver is identified with a network sequence and a recipient sequence both included in the message, wherein the network sequence is a group identifier, such as a network identifier, and has better autocorrelation properties than the recipient sequence.
