The PDCAB packet (300) and the RRA packet (308) are transmitted together on the F-SCCH. For example, 9 RRA bits (305) are appended to the PDCAB field (303), in place of the pad bits (205), thereby allowing both the PDCAB (303) and RRA (311) messages to be protected against errors by a 16-bit CRC (307). In accordance with the embodiments, a receiver is able to distinguish between the varying PDCAB (303) and RRA (305) message formats and transmitting the packets (300) and (308) together is a normal mode of operation in the embodiments. Therefore, in accordance with the embodiments, when the PDCAB packet (300) and RRA packet (308) are transmitted together, the network replaces the N PDCAB pad bits, such as pad bits (205), with the first N bits from the RRA bitmap (311), in order to use the nominal CRC length for both packets (300) and (308).
L'invention concerne le paquet PDCAB (300) et le paquet RRA (308) qui sont transmis ensemble sur le F-SCCH. Par exemple, 9 bits RRA (305) sont ajoutés au champ PDCAB (303), au lieu des bits de pastille (205), en permettant ainsi de protéger les messages PDCAB (303) et RRA (311) contre des erreurs par un CRC 16 bits (307). Selon les modes de réalisation, un récepteur peut distinguer les formats de messages PDCAB (303) et RRA (305) variables, et la transmission des paquets (300) et (308) ensemble est un mode de fonctionnement normal dans les modes de réalisation. Par conséquent, selon les modes de réalisation, lorsque le paquet PDCAB (300) et le paquet RRA (308) sont transmis ensemble, le réseau remplace les N bits de pastille PDCAB, tels que des bits de pastille (205), par les premiers N bits à partir du bitmap RRA (311), afin d'utiliser la longueur CRC nominale pour les paquets (300) et (308).
