摘要： A method for determining associated parameters of beam space is disclosed, which includes: the user terminal receives the common pilot signals which are respectively sent by at least two antennas; when the number of the antennas which need to send the common pilot signals is not more than the number of the antenna ports, the common pilot signals are respectively sent by the antennas through the antenna ports; or, when the number of the antennas which need to send the common pilot signals is more than the number of the antenna ports, the antennas are grouped, and the common pilot signals are sent by antennas of each groups through the antenna ports based on time division multiplex mode, wherein the number of the antennas in each group is not more than the number of antenna ports; and the user terminal determines the associated parameters of each beam space of the user terminal itself according to the received signals respectively sent by at least two antennas. A user terminal for determining associated parameters of beam space, and a method and base station for forming signal are also disclosed. By applying the solutions of this invention, the problem that the associated parameters of each beam space can not be determined accurately in the prior art can be solved.
