1. A method for performing beam measurements in a wireless communication network, comprising:
performing first measurements of a first plurality of beams from a first transmission and reception point (TRP) of a network, wherein the first plurality of beams comprise non-single- frequency network (SFN) beams;
performing second measurements of a second plurality of beams, wherein each beam of the second plurality of beams is from a plurality of TRPs of the network, and wherein the second plurality of beams comprise SFN beams;
applying a first biasing factor to the first measurements based on the non-SFN beams and a second biasing factor to the second measurements based on the SFN beams, wherein the first biasing factor is different than the second biasing factor, wherein the second biasing factor is equal to one minus the first biasing factor;
selecting a best beam from the first plurality of beams based on the first measurements;
selecting a best beam from the second plurality of beams based on the second measurements; and
transmitting, to the network, a measurement report comprising:
a measurement of the best beam from the first plurality of beams; and
a measurement of the best beam from the second plurality of beams.
