Method of the invention is described in detail with specific embodiment below.It is worth noting that in following tool First ray is otherwise known as leading frequency sequence in body embodiment, and the second sequence is otherwise known as leader sequence or mask code sequence.

Specific embodiment one

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

All wave beams are divided into 4 groups, wherein there are many kinds of division principles, such as: lesser wave beam will be interfered to divide To same group, biggish wave beam is interfered to be divided in different groups, or biggish wave beam will be interfered to be divided into same group, Lesser wave beam is interfered to be divided in different groups etc..In the embodiment of the present invention, for the ease of the description of method below, every company 4 continuous wave beams are divided into one group, i.e. wave beam 0~3 forms the first wave beam group (being also referred to as wave beam group 0 below), wave in Fig. 2 Beam 4~7 forms the second wave beam group (being also referred to as wave beam group 1 below), and wave beam 8~11 forms third wave beam group and (is also referred to as below For wave beam group 2), wave beam 12~15 forms the 4th wave beam group (being also referred to as wave beam group 3 below).

For same frequency resource, different beams group, which is located on different time quantums, to be sent, the wave in same wave beam group Beam, which is located on identical time quantum, to be sent.The pilot tone of the channel measurement pilot frequency sent on different beams in same wave beam group Sequence is different, distinguishes corresponding wave beam using different pilot frequency sequences for receiving side.

The mode mutually distinguished between the pilot frequency sequence of the channel measurement pilot frequency sent from the wave beam in same wave beam group Have in very much, such as several ways below:

Mode one:

Beam index mark is added before the leading frequency sequence that each wave beam to be sent, as shown in Figure 3.Wherein, it dominates 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..Fig. 5 In show channel measurement pilot frequency sequence on 0 different beams of wave beam group, sent on 4 wave beams in the same wave beam group Channel measurement pilot frequency sequence consists of two parts, i.e. beam index mark (0000,0001,0010 and 0011 in such as Fig. 5) With leading frequency sequence.Wherein,

The leading frequency sequence in channel measurement pilot frequency sequence on 4 wave beams is identical, each respective wave beam of wave beam It indexes as the beam index mark for constituting its channel measurement pilot frequency sequence, for distinguishing the different waves in the same wave beam group Beam.

For example, the beam index of 4 wave beams in wave beam group 0 is followed successively by 0~3, bit map (bit can be used respectively Map it) 0000,0001,0010,0011 indicates；The beam index of 4 wave beams in wave beam group 1 is followed successively by 4~7, Ke Yifen It is not indicated with bit map 0100,0101,0110,0111；The beam index of 4 wave beams in wave beam group 2 is followed successively by 8~ 11, bit map 1000,1001,1010,1011 can be used respectively；The beam index of 4 wave beams in wave beam group 3 is followed successively by 12~15, it can be indicated respectively with bit map 1100,1101,1110,1111.

Specific embodiment two

It is assumed that Fig. 4 is the beam patterns (pattern) that transmitting terminal is used to send channel measurement pilot frequency.Its In, there are 16 different wave beams altogether in wave beam pattern, be respectively directed to different directions.

All wave beams are divided into 4 groups, wherein there are many kinds of division principles, such as: lesser wave beam will be interfered to divide To same group, biggish wave beam is interfered to be divided in different groups, or biggish wave beam will be interfered to be divided into same group, Lesser wave beam is interfered to be divided in different groups etc..In the embodiment of the present invention, for the ease of the description of method below, every company 4 continuous wave beams are divided into one group, i.e. wave beam 0~3 forms the first wave beam group (being also referred to as wave beam group 0 below), wave in Fig. 4 Beam 4~7 forms the second wave beam group (being also referred to as wave beam group 1 below), and wave beam 8~11 forms third wave beam group and (is also referred to as below For wave beam group 2), wave beam 12~15 forms the 4th wave beam group (being also referred to as wave beam group 3 below).

For same frequency resource, different beams group, which is located on different time quantums, to be sent, the wave in same wave beam group Beam, which is located on identical time quantum, to be sent.By all wave beam groups in wave beam pattern all successively send one time it is occupied Time quantum is referred to as a beam scanning period.It can be seen that a beam scanning period is made of one group of time quantum.

Transmitting terminal sends channel measurement pilot frequency in the way of wave beam group, and specifically the mode of transmission wave beam group is, each The wave beam group index initially sent in the beam scanning period is random, or where the wave beam group according to starting transmission The index of time quantum, serving cell ID (i.e. Physical Cell Identifier (Physical Cell Identity, abbreviation PID)), void Quasi- cell ID (Virtual Cell Identity, abbreviation VID), user identifier (such as RNTI (Radio Network Temporary Identity, radio network temporary identifier)), network side notice dedicated for determining the wave beam that initially sends At least one of in the parameter of group index, to determine that starting sends wave beam group index；And in next wave beam group scan period Wave beam group transmission sequence be the wave beam group transmission sequence in the previous wave beam group scan period cyclic shift.Wherein, it constitutes The time quantum in each beam scanning period is the time quantum that can be used for sending channel measurement pilot frequency.

In the present embodiment, the starting wavenumber group index in wave beam group sequence can determine in the following way:

BID_i=XIDmodN；

Wherein c_init=XID；

BID₂=(BID₁+Δ)modN；

Wherein, BID_iIndicate the home beam group index of i-th (i=1 or 2) wave beam group sequence；N indicates wave beam group number c () indicates that pseudo-random sequence Gold sequence generates formula, c_initIndicate the initialization value that pseudo-random sequence Gold sequence generates, Δ is the parameter dedicated for the determination home beam index of network side configuration, and XID indicates Physical Cell Identifier or void Quasi- cell ID or radio network temporary identifier, n_sCharacterization sends the time quantum index of the home beam group.

By taking four wave beam groups of above-mentioned wave beam pattern as an example, as shown in Table 1, the first beam scanning period is by first It is formed to four time quantums, wherein first to fourth time quantum is the time quantum that can be used for sending channel measurement pilot frequency, first On four time quantums in beam scanning period with wave beam group 0 be home beam group successively according to the sequence of wave beam group 0,1,2,3 Send all wave beam groups in above-mentioned wave beam pattern；Home beam group index is 1 on second beam scanning period, then Wave beam group successively is sent according to the sequence of wave beam group 1,2,3,0 on four time quantums in second beam scanning period, In the transmission sequence of wave beam group on the second beam scanning period be just wave beam group transmission sequence in the first scan period Wave beam group transmission sequence after cyclic shift one backward；In the beam scanning period after similarly, determined according to ad hoc fashion After home beam group, the wave beam group transmission sequence in the place beam scanning period was still in a upper beam scanning period Wave beam group transmission sequence cyclic shift.
