In inventive embodiments, which comprises
S201, the network equipment determine r synchronization according to the holding time of unlicensed spectrum channel in m synchronization signal block
Block.
Specifically, preset duration is a time interval, initial time, duration and the end time of preset duration can
To be preconfigured, such as: the duration of preset duration is 5ms, and preset duration periodically occurs.M is preset duration
The maximum quantity for the synchronization signal block for inside including, i.e. preset duration include up to m synchronization signal block.M and currently used son
Carrier wave interval k is related, and m synchronization signal block includes p synchronization signal block of the subcarrier spacing k in the case where authorizing spectral channel, in advance
If the quantity s for the time slot that duration includes is related with subcarrier spacing k.
Such as: referring to fig. 2 shown in b, Fig. 2 b is the distribution signal of 4 synchronization signal blocks under subcarrier spacing is 15kHz
Figure, preset duration is 5ms in figure 2 c, and preset duration includes 5 time slots (slot), and each time slot includes 14 symbols, each
Synchronization signal block corresponds to 4 symbols, and 4 synchronization signal blocks are located at the 2nd symbol of the first two time slot to the 5th symbol,
And the 8th symbol is to the 11st symbol；The synchronization signal block index of 4 synchronization signal blocks uses SSB#0, SSB#1, SSB# respectively
2 and SSB#3 is indicated.
The network equipment monitors the state of unlicensed spectrum channel in preset duration, is listening to unlicensed spectrum channel
When idle, the transmission time window on unlicensed spectrum channel is determined, then determine the complete r synchronization in transmission time window
Block.
In a kind of possible embodiment, do not overlapped between each synchronization signal block in m synchronization signal block.
Specifically, each synchronization signal block occupies n symbol, in preset duration other than p synchronization signal block
Time-domain resource, only there is continuous n symbol, so that it may configure a synchronization signal block.
Such as: the example of c according to fig. 2, white symbol is the time domain other than p synchronization signal block in preset duration
Resource, 5 × 14-4 of residue × 4=54 symbol can increase 1 newly simply by the presence of continuous 4 symbols for this 54 symbols
A synchronization signal block, therefore 12 synchronization signal blocks can be increased in Fig. 2 c newly, preset duration includes 16 synchronization signal blocks, m=
16.It is the distribution schematic diagram of the synchronization signal block increased newly in Fig. 2 b referring to fig. 2 shown in c, in Fig. 2 c, m=16, preset duration packet
Include 16 synchronization signal blocks.
In a kind of possible embodiment, preset duration 5ms, subcarrier spacing k=15kHz, preset duration when
Gap quantity s=5, authorizes the quantity p=8 of synchronous block under spectral channel, m=15, include in preset duration in authorization frequency
Referring to fig. 2 shown in d, 8 synchronization signal blocks occupy in the time slots of front 4 distributing position of 8 synchronization signal blocks under spectrum channel
The 2nd symbol to the 5th symbol and the 8th symbol to the 11st symbol.15 synchronization signals for including in preset duration
The distributing position of block is referring to fig. 2 shown in e.
In a kind of possible embodiment, preset duration 5ms, subcarrier spacing k=30kHz, preset duration when
Gap quantity s=10 authorizes the quantity p=4, m=33 of synchronous block under spectral channel；Or
Preset duration is 5ms, subcarrier spacing k=30kHz, the number of timeslots s=10 of preset duration, authorizes spectral channel
The quantity p=8, m=32 of lower synchronous signal frequency domain resource；Or
Preset duration is 5ms, subcarrier spacing k=30kHz, the number of timeslots s=10 of preset duration, authorizes spectral channel
The quantity p=4, m=35 of lower synchronous block；Or
Preset duration is 5ms, subcarrier spacing k=30kHz, the number of timeslots s=10 of preset duration, authorizes spectral channel
The quantity p=8, m=34 of lower synchronous signal frequency domain resource；Or
Preset duration is 5ms, subcarrier spacing k=120kHz, the number of timeslots s=40 of preset duration, is authorized under frequency spectrum
The quantity p=64, m=140 of synchronization signal frequency domain resource；Or
Preset duration is 5ms, subcarrier spacing k=240kHz, the number of timeslots s=80 of preset duration, is authorized under frequency spectrum
The quantity p=64, m=280 of synchronization signal block.
Specifically, be not overlapped between m synchronization signal block, i.e., it is continuously distributed between the adjacent synchronization signal block of any two
Or discontinuous distribution, the distributing position for m synchronization signal block for including in the preset duration of 5ms can refer to the side of Fig. 2 b to Fig. 2 e
Formula, details are not described herein again.
In a kind of possible design, each synchronization signal block is in discontinuous distribution in m synchronization signal block.
Specifically, being separated with one or more symbols between any two synchronization signal block in m synchronization signal block.It will
Newly-increased synchronization signal block and existing p synchronization signal block are divided into synchronization signal group, and each synchronization signal includes at least one
Or multiple continuous and nonoverlapping synchronization signal block, then being spaced one or more symbols between each synchronization signal group.Actually
That is between newly-increased synchronization signal block, and can be in company between newly-increased synchronization signal block and existing synchronization signal
Continuous distribution, can also be in discontinuous distribution.Can be continuous with several synchronization signals, be then spaced one or more symbols and then
There is synchronization signal.That is do not emphasize there is interval between every two.This interval main purpose is for unlicensed spectrum
The channel-monitoring time, when different synchronization signal block groups indicates different wave beams (beam), the synchronization signal of each beam
Block group will carry out channel-monitoring before sending.
It is obvious that the quantity of newly-increased synchronization signal block be certainly less than it is continuous equal between mentioned-above synchronization signal block
Quantity when distribution.
It is overlapped between each synchronization signal time domain in m synchronization signal block in a kind of possible design.
Specifically, there may be the symbol of overlapping between two adjacent synchronization signal blocks, packet in preset duration when overlapping
The maximum quantity for the synchronization signal block that preset duration includes when the maximum quantity of the synchronization signal block included is not overlapped significantly greater than.Example
Such as: when not being overlapped, the maximum quantity of the preset duration synchronization signal block that includes under subcarrier is 15kHz is 16, and subcarrier is
The maximum quantity for the synchronization signal block that the preset duration of 30kHz includes is 35, and subcarrier is that the preset duration of 120KHz includes
The maximum quantity of synchronization signal block is 140, and subcarrier is the maximum quantity for the synchronization signal block that the preset duration of 240KHz includes
It is 280.When being so overlapped, subcarrier is that the maximum quantity for the synchronization signal block that the preset duration under 15kHz includes is greater than 16,
Subcarrier is that the maximum quantity for the synchronization signal block that the preset duration of 30kHz includes is greater than 35, and subcarrier is the default of 120KHz
The maximum quantity for the synchronization signal block that duration includes is greater than 140, and subcarrier is the synchronization signal that the preset duration of 240KHz includes
The maximum quantity of block is greater than 280.

Number block.16 synchronization signal blocks are indicated with 0000~1111.
Subcarrier spacing is 120kHz, m=140, in order to indicate 140 synchronization signals, needs to carry out table using 8 bits
Show.
It is 240kHz, m=288 in subcarrier spacing, in order to indicate 280 synchronization signals, needs to come using 9 bits
It indicates.
In a kind of possible embodiment, the m-p in the m synchronization signal block in addition to p synchronization signal block is a
Synchronization signal block, the synchronization signal block index of any one synchronization signal block synchronous is believed for described p in m-p synchronization signal block
Randomly selected synchronization signal block index in number block.
Specifically, newly-increased synchronization signal block is multiplexed existing synchronization signal block (p synchronous letter under authorization spectral channel
Number block) synchronization signal block index (SSB index), that is to say, that do not need to support the downlink of user under unlicensed spectrum channel
Synchronous, the synchronization signal under unlicensed spectrum channel is only used as a discovery reference signal for finding unlicensed spectrum place
