Claim 3:
4. The method according to claim 1, further comprising:
for each of the plurality of UEs of the multi-user transmission system, obtaining, by the base station, second source information corresponding to the UE;
extracting, by the base station, a semantic feature of the second source information to obtain a second semantic feature sequence;
performing, by the base station, a joint source-channel coding on the second semantic feature sequence to obtain a second semantic information sequence;
mapping, by the base station, the second semantic information sequence in preset time-frequency resources;
superposing the second semantic information sequences of all the UEs to obtain a second superposition semantic information sequence;
broadcasting the second superposition semantic information sequence through the downlink broadcast channel to each of the UEs of the multi-user transmission system;
receiving, by the UE, the second superposition semantic information sequence; and
obtaining second reconstructed source information according to the second superposition semantic information sequence.
