A method for matching an interference channel codeword in an inter-cell multi-antenna coordinated system, comprising: 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 SNR, with a preset threshold, generating a coordinated multi-point transmission/reception, COMP, policy information according to a comparison result, and transmitting the COMP policy information to a base station; characterized by that, the method further comprises: using a first mark to carry the COMP policy information; and the step of comparing the SINR or the SINR and SNR with the preset threshold and generating the COMP policy information according to the comparison result comprises: if the SINR is greater than a first threshold, a value of the first mark being a first assigned value, to indicate that the user equipment can respond to cooperation requests of other base stations; if the SINR is less than or equal to the first threshold and greater than a second threshold, then the value of the first mark being a second assigned value, to indicate that the user equipment will not participate in cooperation of other base stations when the user equipment does not request other base stations to cooperate, or to indicate that the user equipment is able to respond to the cooperation requests of other base stations when the user equipment requests other base stations to cooperate; and if the SINR is less than or equal to the second threshold, then comparing the SNR with a sixth threshold; when the SNR is greater than the sixth threshold, then the value of the first mark being a third assigned value, to indicate that the user equipment can participate in the cooperation; when the SNR is less than or equal to the sixth threshold, then the value of the first mark being a fourth assigned value, to indicate that the user equipment does not participate in the cooperation. 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 SNR, with a preset threshold, generating a coordinated multi-point transmission/reception, COMP, policy information according to a comparison result, and transmitting the COMP policy information to a base station;
