Wireless communication apparatus for receiving data from multiple transmission and reception points and operating method of the same

An operating method of a wireless communication apparatus receiving data from a first transmission and reception point (TRP) and a second TRP, the operating method comprising:

• receiving a first reference signal from the first TRP and a second reference signal from the second TRP;
• estimating channels of a plurality of subcarriers based on at least one of the first reference signal or the second reference signal to obtain estimated channels;
• determining a beamforming parameter based on the estimated channels, the beamforming parameter being determined based on a capacity of a first effective channel between the wireless communication apparatus and both of the first TRP and the second TRP;
• adjusting a reception beam based on the beamforming parameter to obtain an adjusted reception beam;
• and
• receiving a first physical downlink shared channel (PDSCH) from the first TRP and a second PDSCH from the second TRP, the first PDSCH being received through the adjusted reception beam.

A wireless communication system for supporting communication between multiple transmission and reception points (TRPs) and a wireless communication apparatus, the wireless communication system comprising:

• a first TRP configured to transmit a first reference signal to the wireless communication apparatus;
• a second TRP configured to transmit a second reference signal to the wireless communication apparatus;
• and
• the wireless communication apparatus configured to
• estimate channels of a plurality of subcarriers based on at least one of the first reference signal or the second reference signal to obtain estimated channels,
• determine a beamforming parameter based on the estimated channels, the beamforming parameter being based on a capacity of an effective channel between the wireless communication apparatus and both the first TRP and the second TRP,
• adjust a reception beam based on the beamforming parameter to obtain an adjusted reception beam,
• receive a first physical downlink shared channel (PDSCH) from the first TRP through the adjusted reception beam, and
• receive a second PDSCH from the second TRP.
