Claim 5:
6. An apparatus, comprising:
a processor; and
a memory coupled to the processor, wherein the memory stores instructions that, when executed by the processor, causes the apparatus to perform operations comprising:
determining a target downlink positive polarization beam and a target downlink negative polarization beam based on M weight sets, wherein each weight set of the M weight sets comprises a phase weight set and an amplitude weight set, different weight sets of the M weight sets comprise a same amplitude weight set, different weight sets of the M weight sets comprise different phase weight sets, and, for each weight set of the M weight sets, both a quantity of phase weights in the respective phase weight set and a quantity of amplitude weights in the respective amplitude weight set are determined based on a quantity of a plurality of channels, wherein M is an even number greater than 0, and wherein the M weight sets are preset; and
obtaining a target downlink signal based on the target downlink positive polarization beam and the target downlink negative polarization beam;

wherein determining the target downlink positive polarization beam and the target downlink negative polarization beam based on the M weight sets comprises:
periodically scanning uplink beams;
determining energy values of all users on the uplink beams in each period, wherein the energy values comprise an uplink positive polarization energy value and an uplink negative polarization energy value;
determining a target uplink positive polarization beam and a target uplink negative polarization beam based on the energy values and a positive-negative polarization orthogonal requirement;
determining the target downlink positive polarization beam based on the target uplink positive polarization beam; and
determining the target downlink negative polarization beam based on the target uplink negative polarization beam.
