Specific implementation mode

In 5G systems, different subcarrier spacings, the time slot that synchronizing signal block is made of at one 14 OFDM symbols In position it is different.The position of two synchronizing signal blocks in the high frequency subcarriers interval of 120KHz a, time slot is in time domain Upper continuous, for the high frequency subcarriers interval of 240KHz, the position of four synchronizing signal blocks in two time slots connects in the time domain It is continuous.

Fig. 1 is position of the synchronizing signal block in the time domain in a time slot under the subcarrier spacing of 120KHz.In Fig. 1 One square can represent an OFDM symbol, and a synchronizing signal block is made of 4 OFDM symbols, wherein in a time slot Can include 2 synchronizing signal blocks, the two synchronizing signal blocks are continuous in the time domain.

Fig. 2 is position of the synchronizing signal block in the time domain in two time slots under the subcarrier spacing of 240KHz.In Fig. 2 One square can represent an OFDM symbol, and a synchronizing signal block is made of 4 OFDM symbols, wherein in two time slots Can include 4 synchronizing signal blocks, this four synchronizing signal blocks are continuous in the time domain.

Base station needs to send in different beam directions when sending synchronizing signal block using unauthorized high band frequency spectrum Different synchronizing signal blocks, and, for each beam direction, when sending synchronizing signal block on the beam direction, need Whether the channel detected on the beam direction is idle, and when determining channel idle, and synchronizing signal is sent on the beam direction Block.

However, due under the subcarrier spacing of high band, multiple synchronizing signal blocks in a time slot or in two time slots It is continuous (as depicted in figs. 1 and 2) in the time domain, therefore, base station is sent completely a synchronous letter on a beam direction After number block, when sending another synchronizing signal block on another beam direction, without time interval for monitoring another wave Whether the channel on Shu Fangxiang is idle, causes base station that can not realize the hair of another synchronizing signal block on another beam direction It send.

For example, for two synchronizing signal blocks shown in FIG. 1, base station is sent completely first on a beam direction After a synchronizing signal block, when sending second synchronizing signal block on another beam direction, due to first synchronizing signal block Continuous in the time domain with second synchronizing signal block, therefore, base station does not have time interval for monitoring another beam direction Channel it is whether idle, in other words, base station is when whether the channel on detecting another beam direction idle, it will loses the Two synchronizing signal blocks, cause base station that can not complete the transmission to second synchronizing signal block.

Similarly, for four synchronizing signal blocks shown in Fig. 2, base station is sent completely first on a beam direction After a synchronizing signal block, since first synchronizing signal block and second to the 4th synchronizing signal block are continuous in the time domain, because This, also whether the free time is detected the channel on second to the 4th beam direction of no time pair for base station, cause base station without Method is completed to second transmission to the 4th synchronizing signal block.

In this way, once base station can not complete the transmission to synchronizing signal block, mobile terminal will can not receive synchronizing signal Block, and then can not complete to be initially accessed base station.

In order to solve the above-mentioned technical problem, the embodiment of the present application provides a kind of sending method and device of synchronizing signal, can Under unauthorized high spectrum, to ensure that the transmission to continuous multiple synchronizing signal blocks in time domain is completed in base station, and then ensure Mobile terminal can complete the initial access to base station.

In step 302, under unauthorized high spectrum, base station is sending continuous multiple synchronizing signal blocks in the time domain Before, continuous prewired seated position of the multiple synchronizing signal block in unit time slot in the time domain can be obtained.

The unit time slot can be the corresponding a cycle time slot of continuous the multiple synchronizing signal block in the time domain, It can specifically be determined according to different subcarrier spacings, if for example, subcarrier spacing is 120KHz, the unit time slot can be with A corresponding time slot, an interior time slot includes two continuous synchronizing signal blocks in the time domain；If subcarrier spacing is 240KHz, Then the unit time slot can correspond to two time slots, include four continuous synchronizing signal blocks in the time domain in two time slots.

The prewired seated position can be in 5G systems, as defined in 3GPP RAN1AdHoc#2 and RAN1#90 meetings, no Position of the synchronous block in the unit time slot under subcarrier spacing.For example, under the subcarrier spacing of 120KHz, institute The position for stating continuous synchronizing signal block in 2 time domains that prewired seated position can be as shown in Figure 1, between the subcarrier of 240KHz Under, the position of continuous synchronizing signal block in four time domains that the prewired seated position can be as shown in Figure 2.

In step 302, base station acquire in the time domain continuous multiple synchronizing signal blocks in unit time slot After prewired seated position, step 304 can be executed.

Step 304：The prewired seated position is adjusted so that multiple synchronizing signal blocks are in the unit time slot It is discontinuous in interior time domain.

In step 304, base station continuous multiple synchronizing signal blocks on getting time domain are prewired in unit time slot After seated position, the prewired seated position can be adjusted so that continuous multiple synchronizing signal blocks are in time domain in the time domain It is upper discontinuous, in order to which whether base station can idle for monitoring the channel on beam direction with having time.

The embodiment of the present application can be right respectively by taking the subcarrier spacing of the subcarrier spacing of 120KHz and 240KHz as an example The specific implementation mode of step 304 is illustrated.Including：

As shown in figure 4, after adjusting the positions of two synchronizing signal blocks after prewired seated position, when not occupying the unit The position of two OFDM symbols of the position and rearmost end of three OFDM symbols of front end in gap.As shown in figure 5, adjustment is pre- Behind the position of two synchronizing signal blocks after allocation position, two OFDM symbols of front end in the unit time slot are not occupied Position and rearmost end two OFDM symbols position.

It should also be noted that, under the subcarrier spacing of 120KHz, it is believed that when an OFDM symbol is occupied Whether the channel that long enough base stations are detected on a beam direction is idle.In practical applications, two after prewired seated position are adjusted The number for the OFDM symbol being spaced between a synchronizing signal block can according to base station detect the channel whether idle required time and Fixed, specifically, the occupied duration of OFDM symbol being spaced between two synchronizing signal blocks needs to detect channel not less than base station Whether the idle required time, in this way, base station can be used to monitor channel on different beams direction with having time it is whether idle.

In the embodiment of the present application, if subcarrier spacing is 240KHz, the prewired seated position is adjusted so that more A synchronizing signal block is discontinuous in the time domain in the unit time slot, including：

The unit time slot corresponds to 28 OFDM symbols in two continuous time slots, in the time domain the continuous synchronization The number of block is 4, after being adjusted to the prewired seated position of four synchronizing signal blocks：

Three are continuously spaced one in the time domain between the synchronizing signal block and another described synchronizing signal block Or multiple OFDM symbols；Or,

Two the continuous synchronizing signal block and other two continuous synchronizing signal in the time domain in the time domain One or more OFDM symbols are spaced between block；Or,

Two in the time domain the continuous synchronizing signal block discontinuous in the time domain described synchronous believe with other two One or more OFDM symbols are spaced between number block；Or
