A reception device (200a) transmits reception device state information indicating a modulation scheme with which the reception device is compatible, and a channel encoding method. Based on the reception device state information received, a transmission device determines a mapping method for a downlink signal to be transmitted to the reception device (200a). When the reception device (200a) is compatible with BICM-ID, the reception device (200a) transmits reception device state information indicating that the reception device (200a) is compatible with the BICM-ID. Accordingly, the backward compatibility with a communication system using gray mapping can be maintained, and the BICM-ID can be applied.

A source apparatus writes, in a route request packet, the number of routes requested by the source apparatus. When a relay apparatus receives a route request packet for the first time, the relay apparatus determines a waiting time period, based on a route evaluation value that indicates a state of a route through which the route request packet has passed, and starts a timer. The relay apparatus selects route request packets having as high route evaluation values as possible, among route request packets that have been received until the timer expires, the number of route request packets to be selected being equal to the number of routes requested by the source apparatus, and then broadcasts the selected route request packets.

A method, system and computer-usable medium are disclosed for providing information related to a user address as used in a communication session. A tag processing module is implemented for processing tags related to a user. A first user selects a second user to receive a message to initiate a communication session. The message recipient's tags, along with their preferred communication method(s) are displayed within the message sender's messaging client. The message sender then composes and sends a message to the message recipient, using the message recipient's preferred method of communication. The message is received by the message recipient and the message sender's tags are displayed within the message recipient's messaging client. If the message recipient decides to respond to the message, then a communication session is conducted. Once the communications session is ended, a linguistic analysis of the communication session is performed by the tag processing module. The message sender's tags are then updated.
