A signal measurement method for measuring a downlink angle of departure in wireless communications, comprising: receiving, by a terminal device, resource configuration information, wherein the resource configuration information comprises configuration information of a first reference signal set, the first reference signal set comprises M reference signals, N reference signals in the M reference signals are reference reference signals, M is an integer greater than 1, and N is an integer greater than 1, wherein the terminal device selects one or more reference signals with a largest reference signal received power (RSRP) as the N reference reference signals, or one or more reference signals with a shortest delay as the N reference reference signals; receiving, by the terminal device, the M reference signals; determining, by the terminal device, N first paths corresponding to the N reference reference signals, and determining M*N received powers of the M reference signals on the N first paths; and reporting, by the terminal device, a measurement result, wherein the measurement result comprises K*N received powers in the M*N received powers, and K≤M, wherein the measurement result further comprises delays of N-1 first paths, in the N first paths except a reference first path, relative to the reference first path; wherein the N reference reference signals correspond to N spatial receive filters; and M received powers of the M reference signals on any first path j in the N first paths are M received powers, on the first path j, of the M reference signals received by using a spatial receive filter corresponding to a reference reference signal corresponding to the first path j. receiving, by a terminal device, resource configuration information, wherein the resource configuration information comprises configuration information of a first reference signal set, the first reference signal set comprises M reference signals, N reference signals in the M reference signals are reference reference signals, M is an integer greater than 1, and N is an integer greater than 1, wherein the terminal device selects one or more reference signals with a largest reference signal received power (RSRP) as the N reference reference signals, or one or more reference signals with a shortest delay as the N reference reference signals; receiving, by the terminal device, the M reference signals; determining, by the terminal device, N first paths corresponding to the N reference reference signals, and determining M*N received powers of the M reference signals on the N first paths; and reporting, by the terminal device, a measurement result, wherein the measurement result comprises K*N received powers in the M*N received powers, and K≤M, wherein the measurement result further comprises delays of N-1 first paths, in the N first paths except a reference first path, relative to the reference first path; wherein the N reference reference signals correspond to N spatial receive filters; and M received powers of the M reference signals on any first path j in the N first paths are M received powers, on the first path j, of the M reference signals received by using a spatial receive filter corresponding to a reference reference signal corresponding to the first path j.
