Specific embodiment one

As illustrated in fig. 2, it is assumed that Fig. 2 is transmitting terminal being used to send the beam patterns (pattern) of channel measurement pilot frequency.Wherein, there are 16 different wave beams altogether in wave beam pattern, different directions are respectively directed to.

All wave beams are divided into 4 groups, wherein division principle there are many kinds, for example：Less wave beam will be disturbed to be divided into same group, disturb larger wave beam to be divided in different groups, or larger wave beam will be disturbed to be divided into same group, disturb less wave beam to be divided in different groups etc..In the embodiment of the present invention, for the ease of the description of method below, every continuous 4 wave beams are divided into one group, that is wave beam 0~3 constitutes the first wave beam group (being also referred to as wave beam group 0 below) in Fig. 2, wave beam 4~7 constitutes the second wave beam group (being also referred to as wave beam group 1 below), wave beam 8~11 constitutes the 3rd wave beam group (being also referred to as wave beam group 2 below), and wave beam 12~15 constitutes the 4th wave beam group (being also referred to as wave beam group 3 below).

For same frequency resource, different beams group is located on different time quantums and sends, and the wave beam in same wave beam group is located on identical time quantum and sends.The pilot frequency sequence of the channel measurement pilot frequency sent on the different beams in same wave beam group is different, and corresponding wave beam is distinguished using different pilot frequency sequences for receiving side.

The mode mutually distinguished between the pilot frequency sequence of the channel measurement pilot frequency sent on the wave beam from same wave beam group have it is many in, such as several ways below：

Mode one：

Beam index mark was added before each wave beam leading frequency sequence to be sent, as shown in Figure 3.Wherein, leading frequency sequence can be pseudo-random sequence, PN (Pseudo-noise Sequence, pseudo noise sequence) sequence, CAZAC (Const Amplitude Zero Auto-Corelation, permanent envelope zero auto-correlation) sequence or ZC (Zadoff-Chu) sequence etc..The channel measurement pilot frequency sequence on the different beams of wave beam group 0 is shown in Fig. 5, the channel measurement pilot frequency sequence sent on 4 wave beams in same wave beam group is constituted by two parts, i.e. beam index mark (in such as Fig. 5 0000,0001,0010 and 0011) and leading frequency sequence.Wherein,

Receiving side knows the beam information and the corresponding channel quality information of the wave beam measured by the channel measurement pilot frequency sequence using the different channels measurement pilot frequency sequence for receiving.

Mode three：

The channel measurement pilot frequency sequence sent on each wave beam is produced by pseudo-random sequence (such as PN sequences), as shown in Figure 7.Wherein, the initialization value of the PN sequences on different beams is related to beam index.For example PN sequences can be defined as form：
