Method and device for performing coordinated multi-point transmission based on selection of transmission point

A method of performing coordinated multi-point operation by a second transmission point based on transmission point selection, comprising:

• receiving, from the first transmission point, at least a part of a radio resource control (RRC) configuration configured in a user equipment served by a first transmission point;
• receiving, from the first transmission point, a message for requesting to transmit a physical downlink shared channel (PDSCH) to the user equipment;
• and
• transmitting the PDSCH to the user equipment based on the at least a part of the RRC configuration during a duration indicated by the message.

A transmission point performing coordinated multi-point operation based on transmission point selection, comprising:

• a radio frequency (RF) interface configured to transceive a radio signal with a user equipment served by the transmission point;
• a backhaul interface configured to transceive a backhaul link signal with one or more candidate transmission points participating in the coordinated multi-point;
• and
• a processor configured to control the backhaul interface to select a prescribed transmission point from the candidate transmission points and transmit a message for requesting to transmit a physical downlink shared channel (PDSCH) to the user equipment to the prescribed transmission point,
• wherein the message indicates a duration in which the PDSCH is transmitted by the prescribed transmission point.
