Embodiment Construction

[0047] In an exemplary embodiment, the present invention uses the enhanced general packet radio service (EGPRS) modulation and coding scheme MCS-1 to transmit to a reduced transmission time interval (RTTI) mobile station (MS) including CS-1 RLC / MAC control The RLC / MAC control block of the message. MS lookup steal bit codeword=CS-4. If the basic TTI (BTTI) USF mode is used, the inherited stealing bit explained in the inherited BTTI burst sequence is used to send the CS-4 stealing bit codeword. If the RTTI USF mode is used, the bits explained in the RTTI burst sequence are used to send the CS-4 steal bit codeword. Once the MS determines that it has received the CS-4 steal bit codeword, the MS starts to interpret the radio block header as (using the burst pulse explained in the RTTI burst sequence) header type 3 (that is, assuming it has received the MCS- 1 to MCS-4 radio block), and assuming that it is actually sent by the BSS, then check the CPS field to confirm that the MCS-1...

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.

Description

[0001] Related application [0002] This application claims priority of U.S. Provisional Application No. 60 / 895,342 filed on March 16, 2007. Technical field [0003] The invention relates to a wireless communication network. More specifically, but not restrictively, the present invention is directed to a method for transmitting radio link control / media access control (RLC / MAC) control messages to an enhanced general packet radio service (EGPRS) mobile station, and the mobile station A processing unit for detecting the existence of CS-1RLC / MAC control messages in the coding scheme. Background technique [0004] When EGPRS is standardized, legacy GPRS mobile stations (MS) are required to decode the uplink status flag (USF) of the EGPRS radio block. It is also possible to utilize Gaussian Minimum Shift Keying (GMSK) as in the modulation and coding schemes MCS-1 to MCS-4 or to utilize 8-phase shift keying as in the modulation and decoding schemes MCS-5 to MCS-9 ( 8PSK) to modulate th...
