Patent ID: 7835340

Claim:
A method of supporting multiple code types in a wireless mobile communication system, the method comprising: receiving by a mobile station (MS) a downlink channel descriptor (DCD) from a base station (BS), wherein the DCD includes at least one downlink burst profile comprising a type of the at least one downlink burst profile, a downlink interval usage code (DIUC) and type/length/value (TLV) encoded information, wherein a value of the type of the at least one downlink burst profile determines whether a code type is included in the at least one downlink burst profile; and recognizing, by the MS, the code type if the code type is included in the at least one downlink burst profile, wherein the code type indicates a coding scheme to be used by the BS to code a downlink burst associated with the at least one downlink burst profile, wherein the coding scheme is at least one of Block Turbo Code (BTC), Convolutional Turbo Code (CTC), Zero Tail Convolution Code (ZTTC), and Low Density Parity Code (LDPC), wherein when the value of the type of the at least one downlink burst profile is set to 1, the at least one downlink burst profile does not include the code type and the downlink burst associated with the at least one downlink burst profile is encoded by a convolutional code, wherein when the value of the type of the at least one downlink burst profile is set to 153, the at least one downlink burst profile includes the code type for indicating the coding scheme and the downlink burst is encoded by the coding scheme indicated by the code type, wherein the DIUC for the convolutional code is referred to the at least one downlink burst profile with the value of type set to 1.
