1. A method of communication for an apparatus, comprising:sending a plurality of beam reference signals via at least a portion of a plurality of directional beams such that different beam reference signals of the plurality of beam reference signals are sent in different directions;
selecting a channel for transmission of uplink control information to the apparatus, wherein the selection is between a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH);
determining a quantity of beams for which another apparatus is to transmit channel information to the apparatus, wherein the determination of the quantity of beams comprises selecting a first quantity of the plurality of directional beams if the selected channel is the PUSCH and selecting a second quantity of the plurality of directional beams if the selected channel is the PUCCH, wherein the first quantity is larger than the second quantity, and wherein the channel information depends on at least one of: a parameter of a path loss associated with the other apparatus, an angle of departure of a signal from the other apparatus, an angle of arrival of a signal at the apparatus, or any combination thereof;
receiving the channel information for the determined quantity of beams from the other apparatus, wherein the received channel information comprises first reference signal information for the first quantity of beams if the selected channel is the PUSCH and the received channel information comprises second reference signal information for the second quantity of beams if the selected channel is the PUCCH; and
scheduling at least one beam of the plurality of directional beams for traffic based on the received channel information.
