In addition, L synchronization signal block is in 5 milliseconds of times when subcarrier spacing (Subcarrier Space, SCS) is different Position in window is different, as shown in Figure 3.As SCS=15KHz, 1 time slot is including 5 time slots in 1 millisecond, 5 milliseconds, together The maximum number L=4 or L=8 for the synchronization signal block that step signal burst collection can include, as L=4,4 synchronization signal blocks In the first two time slot of half of radio frames；As L=8,8 synchronization signal blocks are located at preceding 4 time slots of half of radio frames In.

As SCS=30KHz, 1 time slot is in 0.5 millisecond, 5 milliseconds including 10 time slots, synchronization signal burst collection institute The maximum number L=4 or L=8 for the synchronization signal block that can include, as L=4, which is located at half of radio frames The first two time slot in；As L=8,8 synchronization signal blocks are located in preceding 4 time slots of half of radio frames.

As SCS=120KHz, 1 time slot is in 0.125 millisecond, 5 milliseconds including 40 time slots, synchronization signal burst collection The maximum number L=64 for the synchronization signal block that can include, it is assumed that the number of 40 time slots is 0 to 39, wherein time slot 0 to when Each time slot in gap 7 includes two synchronization signal blocks, and each time slot of the time slot 10 into time slot 17 includes two synchronization signals Block, each time slot of the time slot 20 into time slot 27 include two synchronization signal blocks, each time slot packet of the time slot 30 into time slot 37 Two synchronization signal blocks are included, then the index of 64 occupied time slots of synchronization signal block is { 0,1,2,3,4,5,6,7 }+10*n, n =0,1,2,3.Wherein, { 0,1,2,3,4,5,6,7 }+10*n, n=0,1,2,3 be equivalent to 0,1,2,3,4,5,6,7,10,11, 12,13,14,15,16,17,20,21,22,23,24,25,26,27,30,31,32,33,34,35,36,37 }.

As SCS=240KHz, 1 time slot is in 0.0625 millisecond, 5 milliseconds including 80 time slots, synchronization signal burst Collect the maximum number L=64 for the synchronization signal block that can include, it is assumed that the number of 80 time slots is 0 to 79, time slot 0 to time slot 15 In each time slot include two synchronization signal blocks, each time slot of the time slot 20 into time slot 35 include two synchronization signal blocks, Then the index of 64 occupied time slots of synchronization signal block be { 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 }+ 20*n, n=0,1.Wherein, { 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 }+20*n, n=0,1 be equivalent to 0, 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,20,21,22,23,24,25,26,27,28,29,30,31,32, 33,34,35}。

In addition, position of the synchronization signal block in time slot is also different when SCS difference.Fig. 4 is provided by the present application various A kind of mapping schematic diagram of the synchronous block in time slot under different SCS.As shown in figure 4, as SCS=15KHz, 1 time slot It is 1 millisecond, 1 time slot includes 14 OFDM symbols, and a synchronization signal block occupies 4 OFDM symbols, and 1 time slot may include two A synchronization signal block, it is assumed that the number of 14 OFDM symbols is 0 to 13 in 1 time slot, then two synchronization signal blocks occupy The index of OFDM symbol is { 2,3,4,5,8,9,10,11 }.

As SCS=30KHz, 1 time slot is 0.5 millisecond, and 1 time slot includes 14 OFDM symbols, and 1 time slot may include Two synchronization signal blocks, two synchronization signal blocks are there are two types of the mapping modes in 1 time slot, it is assumed that 14 in 1 time slot The number of OFDM symbol is 0 to 13, then under the first mapping mode, the index for the OFDM symbol which occupies For { 4,5,6,7,8,9,10,11 }；Under second of mapping mode, the index for the OFDM symbol which occupies is {2,3,4,5,8,9,10,11}。

As SCS=120KHz, 1 time slot is 0.125 millisecond, and 1 time slot includes 14 OFDM symbols, and 1 time slot can Including two synchronization signal blocks, it is assumed that the number of 14 OFDM symbols is 0 to 13 in 1 time slot, then two synchronization signal blocks The index of the OFDM symbol of occupancy is { 4,5,6,7,8,9,10,11 }.

As SCS=240KHz, 1 time slot is 0.0625 millisecond, and 1 time slot includes 14 OFDM symbols, synchronization signal Block is needed across time slot mapping, for example, the 1st time slot may include 1.5 synchronization signal blocks, the 2nd time slot may include 2.5 synchronizations Block.

As can be seen from the above description, when carrier frequency is in the range of 3GHz to 6GHz, i.e., the network equipment sends signal Carrier frequency in the range of 3GHz to 6GHz when, base station within half of radio frames corresponding time be 5 milliseconds of time windows in 8 synchronization signal blocks can only be at most sent, if base station there are 4 beam directions, base station sends 2 together on each beam direction Block is walked, the number for the synchronization signal block that terminal device receives on same beam direction is less, and the gain of acquisition is smaller, It is unable to satisfy the covering demand of Next-Generation Wireless Communication Systems synchronization signal.In order to solve this problem, present applicant proposes when load When wave frequency rate is in the range of 3GHz to 6GHz, base station is most in 5 milliseconds of time windows within half of radio frames corresponding time The scheme of 16 synchronization signal blocks can be sent.

Under normal conditions, the synchronization signal block that base station is sent in 5 milliseconds of time windows is more, then base station is in each wave beam side The synchronization signal block sent up is also more, and the synchronization signal block that terminal device can receive on same beam direction is also got over More, the merging gain obtained after terminal device merges each synchronization signal block on same beam direction is also bigger. When carrier frequency is in the range of 3GHz to 6GHz, if base station is 5 milliseconds of time windows within half of radio frames corresponding time There are 4 beam directions in 16 synchronization signal blocks of interior most transmissions, base station, then base station can be transmitted 4 together on each beam direction Block is walked, at most sends 8 synchronization signal blocks in 5 milliseconds of time windows compared to the network equipment, terminal device is in same wave It can receive more synchronization signal blocks on Shu Fangxiang, to obtain bigger gain, it is same to meet Next-Generation Wireless Communication Systems Walk the covering demand of signal.

Below in conjunction with specific application scenarios, to 16 synchronization signal blocks in the time window of half of radio frames i.e. 5 millisecond Mapping mode be introduced.

A kind of specific application scenarios are: when carrier frequency is in the range of 3GHz to 6GHz, when SCS=30KHz, and 1 Time slot is 0.5 millisecond, and it includes 10 time slots that half of radio frames is in 5 milliseconds of time windows in the time domain, and each time slot is in the time domain Including 14 OFDM symbols, then half of radio frames include 140 OFDM symbols in the time domain, and half of radio frames are corresponding The number of 140 OFDM symbols is 0 to 139.In such a scenario, 16 synchronization signal blocks are mapped in can in half of radio frames 16 synchronization signal blocks are mapped in 140 OFDM symbols with regarding as.

Specifically, it may include following several feasible that 16 synchronization signal blocks, which are mapped in 140 OFDM symbol upper types, Implementation:

One kind is feasible to be achieved in that: 8 synchronization signal blocks preceding in 16 synchronization signal blocks being mapped to described In half of radio frames in the corresponding OFDM symbol of preceding 5 time slots, 8 synchronization signal blocks after in 16 synchronization signal blocks are reflected After being mapped in half of radio frames in the corresponding OFDM symbol of 5 time slots, and first 8 synchronous letters in 16 synchronization signal blocks Number mapping mode of block and the mapping mode of rear 8 synchronization signal blocks are identical.

As shown in figure 5, as SCS=30KHz, 1 time slot is 0.5 millisecond, when half of radio frames is 5 milliseconds in the time domain Between include 10 time slots in window, the number of time slot is 0 to 9.It base station, can be same by 16 before sending 16 synchronization signal blocks Preceding 8 synchronization signal blocks in step block are mapped on time slot 0 to the corresponding OFDM symbol of time slot 4, by 16 synchronization signals Rear 8 synchronization signal blocks in block are mapped on time slot 5 to the corresponding OFDM symbol of time slot 9.Since 1 time slot can put 2 together Block is walked, therefore, in time slot 0 into time slot 4, preceding 8 synchronization signal blocks can be mapped in time slot 0 to the corresponding OFDM of time slot 3 On symbol, time slot 4 does not put synchronization signal block.In time slot 5 into time slot 9, rear 8 synchronization signal blocks can be mapped in time slot 5 to when In the corresponding OFDM symbol of gap 8, time slot 9 does not put synchronization signal block.Specifically, first 8 synchronous letters in 16 synchronization signal blocks Number mapping mode and rear 8 synchronization signal block of the block on time slot 0 to the corresponding OFDM symbol of time slot 3 is right to time slot 8 in time slot 5 The mapping mode in OFDM symbol answered is consistent.
