Patent ID: 8792881

Claim:
A coordinated multi-point (CoMP) transmission execution cell determination method in a wireless communication system for performing coordinated multi-point transmission in a multi-cell environment, the method comprising: determining, by a serving base station, a terminal to perform the CoMP transmission among terminals in a serving cell, the determining the terminal to perform the CoMP transmission among the terminals in the serving cell being performed by the serving cell based on signals from the terminals regarding channel quality in the serving cell; directing, by the serving base station, the terminal, determined to perform the CoMP transmission, to collect first measurement information on adjacent cells; receiving the first measurement information on adjacent cells from the terminal to prepare a candidate cell list to perform the CoMP transmission based on the first measurement information; transmitting the prepared candidate cell list to the terminal and instructing the terminal to collect second measurement information on candidate cells included in the candidate cell list to perform coordinated multi-point transmission; receiving the second measurement information from the terminal and determining adjacent cells to perform coordinated multi-point transmission in a range of predetermined number of cells based on the received second measurement information; and transmitting information on the determined adjacent cells to the terminal.
