The first, the terminal is according to the training signal and the wave beam grouping information, from N number of descending send wave T descending transmission wave beams for belonging to different grouping are determined in beam.

With N=4, exemplified by M=4, in the embodiment of the present invention, for 4 descending wave beams that send using A, B, C, D as representative, 4 descending It is representative that wave beam, which is received, with A ', B ', C ', D ', and the descending grouping information for sending wave beam represents, AB is one in descending transmission wave beam Group, CD are one group.It is then descending transmission wave beam A and descending transmission wave beam D to determine T descending transmission wave beams.Here T=2.

Specifically determination process can be:Terminal is first selected under receiving power highest from all descending transmission wave beams Row sends wave beam as first wave beam in T wave beam, might as well be set to descending transmission wave beam A;Then terminal is again under removing It is T that receiving power highest wave beam is selected in other wave beams outside all wave beams in packet where row transmission wave beam A Second wave beam in wave beam, second wave beam is descending transmission wave beam D in this example.If T is more than 2, its selection course is similar: From N number of descending all wave beams sent in the packet removed in wave beam where the wave beam selected, from remaining wave beam Select one wave beam of receiving power highest.

If T value is determined by terminal, the threshold value of a received signal power can be preset, terminal it is determined that under When row sends wave beam, the descending transmission wave beam that all receiving powers are first less than to threshold value excludes, then is pressed from remaining wave beam Descending transmission wave beam is determined according to aforementioned process, the number for the descending transmission wave beam that can determine that out, as T value.
