Abstract
Methods, systems, and devices for wireless communications are described that provide sequences of spreading codes and hopping patterns that may be used in non-orthogonal multiple access (NOMA) communications between a user equipment (UE) and a base station. A codebook of spreading codes and the associated hopping patterns may be systematically constructed by closed form formulas or look up table. The base station may receive multiple concurrent transmissions from multiple different UEs, and the sequences of spreading codes and hopping patterns, may be used to identify a particular UE of the multiple UEs.
