The embodiment of the present document provides a method for matching an interference channel codeword in an inter-cell multi-antenna coordinated system, including: a user equipment obtaining a signal to interference plus noise ratio (SINR), or obtaining a SINR and a signal to noise ratio (SNR), and comparing the SINR, or the SINR and the SNR, with a preset threshold, generating coordinated multi-point transmission/reception (COMP) policy information according to a comparison result, and transmitting the COMP policy information to the base station. The present document further provides a user equipment.
