In a mobile communication system, an error detection code or a quality frame indicator (e.g., CRC) is generated using selectively frame information, and at least one of a WCA identifier of another terminal, and a corresponding terminal identifier. And the terminal identifier can be implicitly transmitted to the receiver.

1. A method of transmitting signals via a physical channel in a mobile communication system, the method comprising: attaching a first error detection code to a first sequence to generate a second sequence, wherein the first error detection code is generated based on the first sequence by using a first cyclic redundancy code generator polynomial;attaching a second error detection code to at least a part of the second sequence to generate a third sequence, wherein the second error detection code is generated based on at least a part of the second sequence by using a second cyclic redundancy code generator polynomial; andtransmitting the third sequence via the physical channel defined without header, wherein the physical channel comprises control information to be processed in a physical layer for transmission of data. 2. The method of claim 1, wherein the physical channel comprises the control information multiplexed with data unit. 3. The method of claim 1, wherein the control information comprises quality indicator, and wherein the quality indicator is multiplexed with data unit. 4. The method of claim 1, wherein the first cyclic redundancy code generator polynomial and the second cyclic redundancy code generator polynomial are different from each other. 5. The method of claim 4, wherein the first error detection code is masked with a terminal identifier. 6. The method of claim 5, wherein the terminal identifier is a Medium Access Control (MAC) identifier. 7. The method of claims 6, wherein the terminal identifier identifies a terminal. 8. The method of claims 7, wherein the first sequence comprises variable size information corresponding to an encoder packet size field, an ARQ channel identifier field, a subpacket identifier field, a walsh code allocation field and a sequence number field. 9. The method of claim 7, wherein the second sequence further comprises encoder tail bits. 10. The method of claim 9, wherein the first error detection code is masked with the terminal identifier using a modulo-2 operation. 11. The method of claim 10, wherein the modulo-2 operation is an exclusive OR operation. 12. The method of claim 11, wherein the masked first error detection code and the second error detection code have an identical length.
