Method and apparatus for beam management reference signals in wireless communication systems

A base station (BS) for a beam management in a wireless communication system, the BS comprising:

• a transceiver configured to:
• transmit, to a user equipment (UE), configuration information including information of receive (Rx) beam identifications (IDs) associated with Rx beams and configuration of Rx beam cycling to receive downlink channels,
• transmit, to the UE, a beam reference signal (BRS) and a channel state information-reference signal (CSI-RS), wherein the UE determines the Rx beams based on the BRS and the CSI-RS;
• and
• transmit, to the UE, downlink channels associated with the Rx beams and the Rx beam cycling.

A method of a user equipment (UE) for a beam management in a wireless communication system, the method comprising:

• receiving, from a base station (BS), configuration information including information of receive (Rx) beam identifications (IDs) associated with Rx beams;
• receiving, from the BS, reference signals for determining the Rx beams, wherein the Rx beams include different Rx beam IDs, respectively;
• measuring, based on the Rx beams, a beam reference signal (BRS) and a channel state information-reference signal (CSI-RS) received from the BS;
• and
• performing, based on the configuration information, an Rx beam cycling operation for the Rx beams to receive downlink channels.
