Claim:
1. 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 coordinated multi-point transmission/reception (COMP) policy information according to a comparison result, and transmitting the COMP policy information to a base station; wherein the method further comprises: using a first mark to carry the COMP policy information; 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 other base stations are not requested to cooperate; if the user equipment requests other base stations to cooperate, then the user equipment being able to respond to the cooperation requests of other base stations; and if the SINR is less than or equal to the second threshold, then comparing the SNR with a sixth threshold; if 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; if 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.
