ABSTRACT:
A Method and system for transmitting a signaling message between a base station and a mobile station over a half rate channel are shown. Traffic data is interleaved over k bursts diagonally (4 bursts diagonally in GERAN) and a signaling message is interleaved over m bursts diagonally, where m>k. The method includes transmitting the same encoded signaling message in two consecutive radio packets, where each radio packet is interleaved over k bursts diagonally (the consecutive radio packets have an interleaving depth of 6 in GERAN). By doing so the coded bits of the signaling message are effectively interleaved over two radio packets, and m>k. The receive side of the communication reads the first packet, stores the soft values for decoding, and soft combines them when the second radio packet is received. Diversity may be added by the transmit side. The re-transmission of the second radio packet is preferably mandatory at call set-up.
