Carry out the formation of ground floor wave beam, can from the array of transmitting terminal, select Nt bay, from the array of receiving terminal, select Nr bay, and make antenna elected all in running order, and make remaining bay be in non operating state, for example in 9 bays of transmitting terminal, select 2 bays as in running order bay, all the other 7 bays are as the bay of non operating state, and receiving terminal also can do same setting.
The beam resolution of supporting according to this Nt array element of institute's transmitting terminal work forms N possible beam position, respectively to this N possible M training symbol of direction transmitting, wherein, M be receiving terminal antenna in the situation that of Nr array element participation work, the number of the beam position that can form.
Transmitting terminal antenna, completing after training symbol process of transmitting, transfers accepting state to by transmission state, prepares to receive the feedback information pointing to about optimal beam that receiving terminal bay is sent.
Nr array element of receiving terminal participation work, according to supported beam resolution, forms M beam position, and to this M, a sensing scans receiving terminal successively, extracts the training symbol of transmitting terminal transmitting.Receiving terminal, according to the training signal receiving, is selected optimum beam position, this information is fed back to transmitting terminal simultaneously.
Transmitting terminal in accepting state is receiving after the feedback of pointing to about optimum, increase the element number of array of participation work, make it become Nt ' from Nt, simultaneously, receiving terminal is also increased to Nr ' by the element number of array of the work of participation by Nr, for example, in 9 bays of transmitting terminal, increase by 2 bays as in running order bay, now, 4 in running order bays altogether, all the other 5 bays are as the bay of non operating state, and receiving terminal also can do end is set equally.Transmitting terminal and receiving terminal carry out wave beam formation according to above-mentioned steps again.In the process realizing, the wave beam of this new level forms, and the optimum that its beam position only need obtain in last layer level is searched within pointing to, and without processing remaining beam position.
