摘要
There is a method and apparatus for transmitting a beacon for D2D communications in a first radio resource selected from among a first set of radio resources of a beacon frame; and for transmitting a broadcast message in a second radio resource selected from among a second set of radio resources of the same beacon frame. In various particular embodiments: the beacon has an indication that the broadcast message is to be transmitted in the beacon frame; the beacon has an indication specifying the second radio resource; there is transmitted a broadcast message header in the second radio resource during an initial subframe of the beacon frame and the broadcast message header has an indication of how many subframes are allocated for the broadcast message; and the broadcast message header has a retransmission control field that selectively indicates which broadcast partners are to re-transmit the broadcast message.
