    Abstract: The present invention is directed to a communication device of a wireless communication network, the communication device including a message generator configured to generate a beacon message having a traffic indication map (TIM) information element (IE), wherein the TIM IE includes a partial virtual bitmap field including at least one cluster; a determiner configured to determine for at least one cluster information indicating whether data is available in the communication device to be transmitted to a plurality of communication terminals of the wireless communication network; an encoder configured to determine an encoding mode for the information depending on the information and to encode the information based on the encoding mode; and a transmitter configured to broadcast the beacon message to the plurality of communication terminals corresponding to the at least one cluster. Methods of simultaneously addressing a plurality of communication terminals in the wireless communication network are also disclosed.

    Abstract: Methods and systems are proposed for transmitting data from a source (110) to a destination (130) via a relay station (120) having multiple antennae (122, 124). The relay station (120) receives from the source a message containing the data and a first cyclic prefix. It does this using each of its antennae (122, 124), so producing multiple respective received signals. In certain embodiments, the relay station (120) removes the first cyclic prefix from the received signals, replacing it with a new one. In other embodiments, the relay station (120) removes only a portion of the first cyclic prefix. In either case, the relay station (120) may apply space-time coding to generate second signals, which it transmits to the destination (130), which extracts the data. Methods are also proposed for estimating parameters of the channel, to enable the destination (130) to decode the data.
