Method and device for generating inter-cell information for cancelling inter-cell interference
摘要:
Provided is a method for transmitting and receiving inter-cell information for cancelling inter-cell interference in a wireless communication system. The method for transmitting and receiving inter-cell information may comprise the steps in which: a base station of a victim cell transmits, to a base station of an adjacent aggressor cell, a first PMI set which is a set of PMIs of a signal corresponding to an area partitioned in a predetermined direction; the base station of the aggressor cell transmits, to the victim cell, the signal of the PMIs by using a specific resource; the base station of the victim cell receives, from a terminal in the victim cell, a feedback signal on the signal of the PMIs; the base station of the victim cell transmits, to the base station of the aggressor cell, the feedback information; and the base station of the aggressor cell updates the first PMI set to a second PMI set on the basis of the feedback information, and transmits, to the base station of the victim cell, the updated second PMI set.
