User pairing method and related device

A user pairing apparatus, wherein the apparatus comprises:

• one or more processors;
• a non-transitory memory coupled to the one or more processors, wherein the non-transitory memory stores a program to be executed by the one or more processors, the program including instructions for:
• determining a first generation parameter of a first base sequence of a first user and a second generation parameter of a second base sequence of a second user, wherein the first base sequence is used to generate a first uplink reference signal of the first user, and the second base sequence is used to generate a second uplink reference signal of the second user;
• determining multiplexing evaluation information of the first base sequence and the second base sequence based on the first generation parameter and the second generation parameter, wherein the multiplexing evaluation information comprises at least one of correlation strength between the first base sequence and the second base sequence, and interference leakage information between a first power delay profile of a channel response corresponding to the first uplink reference signal and a second power delay profile of a channel response corresponding to the second uplink reference signal;
• determining, based on the multiplexing evaluation information, that the first user and the second user are successfully paired;
• and
• determining that the first user and the second user multiplex a same communication resource for communication based on being successfully paired,
• wherein after the determining that the first user and the second user multiplex a same communication resource for communication, the method further comprises:
• determining a cyclic shift guard interval between the first base sequence and the second base sequence;
• determining a first cyclic shift value of the second base sequence based on the quantity of second user multiplexing layers and the cyclic shift guard interval;
• and
• performing a cyclic shift on the second base sequence based on the first cyclic shift value to obtain the second uplink reference signal, wherein the second uplink reference signal is used to estimate an uplink channel of the second user when the first user and the second user multiplex the same communication resource for communication.
