Abstract

The present invention relates to a method for transmitting data via a physical channel in a communication system, the channel being used by at least one first communication device and one second communication device and transmitting data with a defined bit rate. According to the present invention, the data to be transmitted (TD) is composed of load data (LD) and identification data (ID) for identifying the second communication device, the load data (LD) and identification data (ID) are coded separately from one another, the respective coding (C_LD, C_ID) takes place in such a way that an identical bit rate is achieved after the coding operation for the load data (LD) and the identification data (ID) and the rate is matched to the bit rate that has been defined for the physical channel by a rate matching mode, which defines which bits are punctured or repeated in a data stream. The rate matching model for load data (LD) and identification data (ID) is identical.

Claims

1. A method for transmitting data with a defined number of bits via a physical channel in a communications system, the physical channel being used by at least one first communication device and one second communication device, the method comprising:

providing that the data to be transmitted is composed of load data and identification data for identifying the second communication device;

separately coding the load data and the identification data from each other using convultional coding, wherein a same number of bits is produced after the coding operation for the load data and the identification data;

linking the coded load data and the coded identification data with each other via an XOR linking operation; and

matching a data rate to the number of bits defined for the physical channel using a rate matching pattern selected from the group consisting of a rate matching pattern used immediately before the XOR linking operation and a rate matching pattern used immediately after the XOR linking operation, the rate matching pattern defining which bits in a data stream have at least one characteristic selected from the group consisting of being punctured and being repeated, wherein the rate matching pattern for the load data and the identification data is identical.

2. A method for transmitting data as claimed in claim 1, wherein the coding operation supplies a bit sequence of bits 1 to n in a defined time window by which the rate is defined, and rate matching is performed via a rate matching pattern by which individual bits in the bit sequence are punctured.

3. A method for transmitting data as claimed in claim 1, wherein the physical channel is a High Speed Shared Control Channel.

4. A method for transmitting data as claimed in claim 1, wherein the identification data is an identification number of a communication device.

5. A method for transmitting data as claimed in claim 2, wherein the rate matching occurs using a rate matching pattern by which bits at positions 1, 2, 4, 8, 42, 45, 47 and 48 are punctured in a bit sequence consisting of n=48 bits.

6. A method for transmitting data as claimed in claim 5, wherein a position of the bits being punctured is shifted by a whole number k, where 0<

k≦

5.

7. A method for transmitting data as claimed in claim 1, wherein linking is bit-by-bit linking.
