Abstract
A method of transmitting a downlink, coding scheme CS-1 RLC/MAC control message from a BSS to an EGPRS MS (61), and receiving and detecting the CS-1 RLC/MAC control message in the MS. The BSS places in an MCS-1 radio block, a CS-1 RLC/MAC control block identical to a coding scheme CS-1 RLC/MAC control message excluding the MAC header octet. The BSS also places a coding scheme CS-4 stealing bit code word in the radio block using legacy stealing bit values and positions. The CPS field (26) of the block header (25) indicates that the radio block contains a CS-1 RLC/MAC control message. The MS receives the radio block and detects the coding scheme CS-4 stealing bit code word. In response, the MS interprets the received radio block header to identify the CPS field. The MS determines from the CPS field that a CS-1 RLC/MAC control block has been received.
