Method and apparatus for multiple transmission and reception point communication in communication system

A method of a terminal, comprising:

• receiving subband configuration information from a first transmission and reception point (TRP);
• receiving subband activation information from the first TRP;
• and
• receiving data from the first TRP through at least one subband based on the received subband configuration information and the received subband activation information.

A first transmission and reception point (TRP) comprising at least one processor, wherein the at least one processor causes the first TRP to perform:

• forming a TRP group including the first TRP and a second TRP;
• configuring at least one first subband in a first operating band of the first TRP by performing a role of a master TRP;
• generating at least one subband group including the at least one first subband;
• setting a transmission (TX) timing and reception (RX) timing for at least one constituent subband of the at least one subband group;
• and
• communicating with a terminal based on the set TX timing and RX timing by using the at least one constituent subband in cooperation with the second TRP.
