Claim 13:
14. A non-transitory computer-readable storage medium storing a program that is executable by one or more processors, the program including instructions for:
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 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 comprise instructions for:
performing beamforming on a to-be-transmitted signal based on the M weight sets, to obtain M beams, wherein the M weight sets comprise N positive polarization weight sets and N negative polarization weight sets, each positive polarization weight set of the N positive polarization weight sets comprises a positive polarization phase weight set, each negative polarization weight set of the N negative polarization weight sets comprises a negative polarization phase weight set, each positive polarization weight set of the N positive polarization weight sets corresponds to one positive polarization beam, and each negative polarization weight set of the N negative polarization weight sets corresponds to one negative polarization beam, wherein M is twice N;
calculating a sum of dedicated physical control channel (DPCCH) transmit powers of all users corresponding to each of the M beams, wherein a sum of DPCCH transmit powers of all users corresponding to the one positive polarization beam is a sum of positive polarization DPCCH transmit powers, and a sum of DPCCH transmit powers of all users corresponding to the one negative polarization beam is a sum of negative polarization DPCCH transmit powers;
determining a beam corresponding to a smallest sum of positive polarization DPCCH transmit powers in N sums of positive polarization DPCCH transmit powers as the target downlink positive polarization beam; and
determining, based on the target downlink positive polarization beam and N sums of negative polarization DPCCH transmit powers, the target downlink negative polarization beam paired with the target downlink positive polarization beam.
