In the application, synchronizing signal block (SS block) is referred to as sweep time block (sweeping time Block) either scanning block (sweeping block) or beam scanning time block (beam sweeping time ) or beam scanning block (beam sweeping block) block.
As shown in figure 4, comprising one or more SS block in each sync window signal (SS burst), for sending out respectively It send the SS of multiple beam directions or port and message signale or repeats to send the SS and message of same port or beam direction Signal.It may search for the synchronizing signal in wherein one or more SS block in terminal synchronization process, and further receive Message signale obtains down-going synchronous and system information to whole system.

Alternatively, the sequence of certain level-one synchronizing signal and the correspondence of synchronizing signal block configuration mode can be predefined, i.e. certain level-one is same The different sequences for walking signal indicate different synchronizing signal block configuration modes.Alternatively, the sequence of multistage synchronizing signal can be predefined Row combination and the correspondence of synchronizing signal block configuration mode；For example, synchronizing signal includes three-level synchronizing signal, three-level synchronizes letter Number combined sequence and synchronizing signal block configuration mode establish correspondence.Or or subcarrier maps mode with it is same The sequence of step signal is combined, and correspondence is established with synchronizing signal block configuration mode；For example, synchronizing signal is same comprising two-stage Signal is walked, i.e. the sequence of the subcarrier maps mode and SSS of PSS and SSS, SSS is established after being combined matches with synchronizing signal block Put the correspondence of mode.Alternatively, can predefine other combinations (for example, the subcarrier maps mode of multistage synchronizing signal with The combination of the sequence of certain level-one synchronizing signal, alternatively, the subcarrier maps mode of certain level-one synchronizing signal and multistage synchronizing signal Sequence combination, alternatively, the combination of the subcarrier maps mode of multistage synchronizing signal and the sequence of multistage synchronizing signal) with it is same Walk the correspondence of block configuration mode.

It should be noted that if the element mapping in subsequence encounters direct current subcarrier, skip direct current subcarrier and reflect Next subcarrier is penetrated, the subcarrier number of the element mapping in follow-up every subsequence can determine according to the following formula：S(n,m) =S0+Sn-0+m×K+1。
Wherein, for certain level-one synchronizing signal, according to the subcarrier maps sequence of N subsequence, it may be determined that exist The different subcarrier maps mode of kind.
For example, certain level-one synchronous signal sequence includes two isometric subsequences, i.e. subsequence 0, subsequence 1；Two Subsequence uses the sub-carrier intercrossed mapping ruler of pectination.In subsequence 0 each element mapping subcarrier number be：S(0,m) =S0+S0-0+ m × K, the subcarrier number of each element mapping in subsequence 1 are：S (1, m)=S0+S1-0+ m × K, m ∈ 0, 1,...,M-1}.This grade of synchronizing signal co-exists inSub-carrier mapping mode.That is mapping mode one：Member in subsequence 0 The subcarrier of 0 mapping of element is the starting subcarrier of this grade of synchronizing signal mapping, then S0-0=0, S1-0It takes more than 0 and whole less than K Number；Mapping mode two：Starting subcarrier of the subcarrier that element 0 in subsequence 1 maps for this grade of synchronizing signal mapping, then S1-0=0, S0-0Take the integer more than 0 and less than K.As shown in figure 8, taking K=2, the son of the element mapping in two subsequences carries Wave offset is 1.According to the difference of subsequence mapping subcarriers sequence, there are two sub-carrier mapping modes as shown in Figure 8, from It and can be with two different transmission modes of instruction message signal.

S (0,0)=S0=60,
S (0,1)=S0+ K=62,
S (0,2)=S0+ 2 × K=64,
...,
S (0, m)=S0+ m × 2=60+2m,
...,
S (0,30)=S0+ 30 × 2=120.
The subcarrier number of element mapping in subsequence 1 is followed successively by：
S (1,0)=S0+S1-0=61,
S (1,1)=S0+S1-0+ K=63,
S (1,2)=S0+S1-0+ 2 × K=65,
S (1,3)=S0+S1-0+ 3 × K=67,
...,
S (1, m)=S0+S1-0+ m × K=61+2m,
...,
