1. A method for a user equipment (UE) device, comprising:
receiving, by the UE device and from a base station serving the UE device, information indicative of an air interface efficiency of the base station serving the UE device;
selecting, by the UE device, a voice coding rate for a voice call involving the UE device based on the information indicative of the air interface efficiency of the base station serving the UE device, the information further comprising at least one of a beamforming capability associated with the base station, a multi-user multiple-input multiple-output (MU-MIMO) capability associated with the base station, or an antenna configuration associated with the base station;
transmitting, by the UE device, an indication of the selected voice coding rate to the base station; and
transmitting, by the UE device, one or more voice frames to the base station during the voice call, wherein the one or more voice frames convey voice data coded at the selected voice coding rate.
