摘要

A method for operating an adapting device includes selecting a first access mode out of a plurality of access modes for a first transmission between a first communications device and a second communications device, wherein the selection of the first access mode is made in accordance with an access mode criterion, and at least one of communications system information, and user equipment information, and determining sparse code multiple access (SCMA) parameters from the first access mode in accordance with a SCMA parameter mapping rule. The method also includes providing information about the first access mode to at least one of the first communications device and the second communications device.

說明書

Each codeword of a respective codebook may be mapped to a different data, e.g., binary, value. As an illustrative example, codewords 211, 221, 231, 241, 251, and 261 are mapped to binary value ‘00’, the codewords 212, 222, 232, 242, 252, and 262 are mapped to the binary value ‘01’, the codewords 213, 223, 233, 243, 253, and 263 are mapped to the binary value ‘10’, and the codewords 214, 224, 234, 244, 254, and 264 are mapped to the binary value ‘11’. It is noted that although the codebooks in FIG. 2 are depicted as having four codewords each, SCMA codebooks in general may have any number of codewords. As an example, SCMA codebooks may have 8 codewords (e.g., mapped to binary values ‘000’ . . . ‘111’), 16 codewords (e.g., mapped to binary values ‘0000’ . . . ‘1111’), or more.
