Claim 5:
6. The method according to claim 4, wherein said determining, by the network equipment, the spread spectrum sequence group used by the terminal for the NOMA multi-layer transmission comprises:
receiving, by the network equipment, configuration information of the spread spectrum sequence group sent by the terminal, and determining the spread spectrum sequence group used by the terminal for the NOMA multi-layer transmission according to the configuration information of the spread spectrum sequence group;
wherein the spread spectrum sequence group is selected by the terminal from a spread spectrum sequence pool, and the spread spectrum sequence pool comprises M spread spectrum sequence groups, spread spectrum sequences in each of the M spread spectrum sequence groups are mutually orthogonal, and M is an integer greater than 1; wherein the spread spectrum sequence pool is preconfigured or agreed by a system.
