Abstract:
1. A method for transmitting in a base station (BS) orthogonal code information to a plurality of mobile stations (MSs) in a mobile communication system, the orthogonal code information used by the MSs to receive a data, the method comprising the steps of: assigning at least one orthogonal code from a plurality of orthogonal codes to a first MS, the plurality of orthogonal codes being indexed by sequential orthogonal indices; assigning at least one orthogonal code from a plurality of orthogonal codes to a second MS, the at least one orthogonal code assigned to the second MS having a next orthogonal code index that follows a last orthogonal code index of the at least one orthogonal code assigned to the first MS; transmitting first control information including first orthogonal code information including the last orthogonal code index of the number of orthogonal codes assigned to the first MS; and transmitting second control information including second orthogonal code information including a last orthogonal code index of the at least one orthogonal codes assigned to the second MS.
