What is claimed is: 1. A control information transmitting method in a base station (BS) of a mobile communication system, the BS transmitting data to a mobile station (MS), and transmitting an identifier (ID) of the MS and control information about the data to the MS, the method comprising the step
What is claimed is: 1. A control information transmitting method in a base station (BS) of a mobile communication system, the BS transmitting data to a mobile station (MS), and transmitting an identifier (ID) of the MS and control information about the data to the MS, the method comprising the steps of: generating first error detection bits; generating second error detection bits by exclusive-OR gating the first error detection bits and the MS ID; generating new control information by attaching the second error detection bits to the control information; and transmitting the new control information. 2. The method of claim 1, further comprising the step of padding a predetermined number of zeroes to the MS ID so that the MS ID has the same number of bits as the first error detection bits. 3. The method of claim 1, further comprising the step of block-encoding the MS ID so that the MS ID has the same number of bits as the first error detection bits. 4. The method of claim 1, wherein the control information includes a Walsh space indicator indicating a Walsh code used for the data. 5. A method of transmitting control information to a second mobile station (MS) in a base station (BS) of the mobile communication system, the BS transmitting data to at least two MSs, transmitting to a first MS first control information about the data and an identifier (ID) of the first MS, and transmitting to a second MS the first control information, second information and the ID of the second MS, the method comprising the steps of: receiving the first and second control information and generating a third control information by attaching first error detection bits to the first and second control information; generating second error detection bits by exclusive-OR gating the first error detection bits with the ID of the second MS; generating fourth control information by attaching the second error detection bits to the second control information; and transmitting the fourth control information. 6. The method of claim 5, further comprising the step of padding a predetermined number of zeroes to the second MS ID so that the second MS ID has the same number of bits as the first error detection bits. 7. The method of claim 5, further comprising the step of block-encoding the second MS ID so that the second MS ID has the same number of bits as the first error detection bits. 8. The method of claim 5, wherein the first control information includes a Walsh space indicator indicating a Walsh code used for the data for the first MS, and the second control information includes a Walsh space indicator indicating a Walsh code used for the data for the second MS. 9. A control information receiving method in a mobile station (MS) of a mobile communication system where a base station (BS) transmits data and error detection control information about the data to the MS, the control information including first error detection bits, the method comprising the steps of: receiving the control information; generating second error detection bits by exclusive-OR gating the first error detection bits with an identifier (ID) of the MS; comparing the first error detection bits with the second error detection bits; and determining that the control information is for the MS if the first error detection bits are identical to the second error detection bits. 10. The method of claim 9, further comprising the step of padding a predetermined number of zeroes to the MS ID so that the MS ID has the same number of bits as the first error detection bits. 11. The method of claim 9, further comprising the step of block-encoding the MS ID so that the MS ID has the same number of bits as the first error detection bits. 12. The method of claim 9, wherein the control information includes a Walsh space indicator indicating a Walsh code used for the data. 13. A control information transmitting apparatus in a base station (BS) of a mobile communication system, the BS transmitting data to a mobile station (MS), and transmitting an identifier (ID) of the MS and control information about the data to the MS, the apparatus comprising: an error detection bit generator for generating first error detection bits; an exclusive-OR operator for generating second error detection bits by exclusive-OR gating the first error detection bits and the MS ID; and a transmitter for generating new control information by attaching the second error detection bits to the control information and transmitting the new control information. 14. The apparatus of claim 13, further comprising a bit inserter for inserting a predetermined number of zero bits to the MS ID so that the MS ID has the same number of bits as the first error detection bits. 15. The apparatus of claim 13, further comprising a block encoder for block-encoding the MS ID so that the MS ID has the same number of bits as the first error detection bits. 16. The apparatus of claim 13, wherein the control information includes a Walsh space indicator indicating a Walsh code used for the data. 17. A control information receiving apparatus in a mobile station (MS) of a mobile communication system where a base station (BS) transmits data and error detection control information about the data to the MS, the control information including first error detection bits, the apparatus comprising: a receiver for receiving the control information; an exclusive-OR operator for generating second error detection bits by exclusive-OR gating the first error detection bits with an identifier (ID) of the MS; and a determiner for comparing the first error detection bits with the second error detection bits and, if the first error detection bits are identical to the second error detection bits, determining that the control information is for the MS. 18. The apparatus of claim 17, further comprising a bit inserter for inserting a predetermined number of zero bits to the MS ID so that the MS ID has the same number of bits as the first error detection bits. 19. The apparatus of claim 17, further comprising a block encoder for block-encoding the MS ID so that the MS ID has the same number of bits as the first error detection bits. 20. The apparatus of claim 17, wherein the control information includes a Walsh space indicator indicating a Walsh code used for the data.
