(Demodulation reference signal, DMRS) is carried.It should be noted that when the DMRS carrying 3 using PBCH
For the information of a bit there are when problem, above-mentioned design can return back to 2 bits.That is, 2 bits in b5b4b3b2b1b0 can benefit
It is carried with the DMRS of PBCH.
In the prior art, when 3 bits in b5b4b3b2b1b0 using the DMRS of PBCH to carry when, complete PBCH
DMRS detection after, the information of 3 bits in SSB TI can be obtained.Frequency range below for 6GHz completes PBCH
DMRS detection after, the information of SSB TI can obtain completely.Then, the boundary of synchronization signal burst collection is assured that.
When 2 bits in b5b4b3b2b1b0 using the DMRS of PBCH to carry when, complete PBCH DMRS detection after, can obtain
Obtain the information of 2 bits in SSB TI.Frequency range below for 3GHz, after completing the DMRS detection of PBCH, SSB TI
Information can obtain completely.Then, the boundary of synchronization signal burst collection is assured that.For the frequency of 3GHz to 6GHz
Range not yet obtains in SSB TI there are also 1 bit information after completing the DMRS detection of PBCH.However, according in 3GPP NR
The boundary of the design that synchronization signal block about 15kHz and 30kHz is constituted, synchronization signal burst collection can determine.
But be 120kHz in subcarrier spacing, synchronization signal period for integrating of burst as in the scene of 5ms, either SSB
3 of TI or 2 bits are carried with the DMRS of PBCH, the boundary of synchronization signal burst collection can not be detected by the DMRS of PBCH come
It determines.In this scene, for multiple SSB, it can not prejudge whether it belongs to the same synchronization signal burst collection, in turn
It can not prejudge whether it belongs to same PBCH TTI.During PBCH soft merging, this uncertainty be will lead to greatly
The blind examination of amount is combined, and the complexity so as to cause terminal demodulation PBCH increases.

Bit；
Step S104: the bit to be sent being carried in corresponding synchronization signal block, and is sent to user equipment, with
The burst collection of synchronization signal belonging to the synchronization signal block received is determined according to the bit to be sent for the user equipment
Boundary.
In specific implementation, in step s101, the digit of bit to be sent is determined.Specifically, the position of bit to be sent
Number can be preset；It is also possible to selected from preset multiple numerical value.Due to bit indicate binary number, by
The digit for sending bit can determine the maximum decimal number that bit to be sent can indicate.For example, the digit of bit to be sent
When being 2, the maximum decimal number that bit to be sent can indicate is 4；When the digit of bit to be sent is 3, bit to be sent can
With the maximum decimal number that indicates for 8.
In specific implementation, each synchronization signal burst collection may include multiple synchronization signal block (Synchronization

Quantity is related to the digit of the bit to be sent.In other words, the quantity of index group can be less than or equal to bit to be sent can be with
The maximum decimal number of expression.
For example, the quantity of index group can be less than or equal to 4 when the digit of bit to be sent is 2；The digit of bit to be sent
When being 3, the quantity of index group can be less than or equal to 8.
In specific implementation, in step s 103, by group number corresponding two belonging to the time index of each synchronization signal block
System number is as bit to be sent.And then in step S104, the bit to be sent is carried on corresponding synchronization signal block
In, and it is sent to user equipment.After then user equipment receives synchronization signal block, which can be determined by bit to be sent
The corresponding group number of block.
In the present embodiment, base station can by synchronization signal happen suddenly collect in all synchronization signal blocks time index it is corresponding to
It sends bit and is sent to user equipment；The time index that synchronization signal burst collection inner part synchronization signal block can also be chosen is corresponding
Bit to be sent be sent to user equipment.
Specifically, there is tactic group number since the burst of each synchronization signal collects interior multiple index groups, use
After family equipment determines group number by bit to be sent, each synchronization signal block can be judged according to the size of each group number whether
Belong to same synchronization signal burst collection, and then can determine the boundary of synchronization signal burst collection.
It is understood that the boundary of synchronization signal burst collection can refer to, the starting time-frequency position of synchronization signal burst collection
Set or terminate time-frequency location；Alternatively, the range of the starting time-frequency location of synchronization signal burst collection or the range of termination time-frequency location.
The embodiment of the present invention is grouped by the time index of all synchronization signal blocks in collecting to synchronization signal burst, so
It is sent to user equipment using the group number of index group as bit to be sent afterwards, so that user equipment can be according to the row of group number
Column sequentially determine the boundary of synchronization signal burst collection, for use in other subsequent operations.
It, can be without demodulating PBCH by determining the boundary of synchronization signal burst collection in a kind of concrete application scene
In the case where, relatively accurate alignment operation is carried out, to meet the diversified demand of user.
Preferably, the sending cycle of the synchronization signal burst collection is 5 milliseconds, the subcarrier of the synchronization signal burst collection
Between be divided into 120KHz.
It is 5 milliseconds in the sending cycle of synchronization signal burst collection, the subcarrier spacing of the synchronization signal burst collection is
Under the scene of 120KHz, the prior art can not determine the boundary of synchronization signal burst collection.And use the synchronization signal of the present embodiment
Happen suddenly the sending method collected, can determine the boundary of synchronization signal burst collection.
It should be noted that the sending cycle in synchronization signal burst collection is other numerical value and/or synchronization signal burst collection
Subcarrier spacing be other numerical value in the case where, for example, the sending cycle that integrates of synchronization signal burst is 20ms, 40ms, 80ms
Deng, subcarrier spacing 240KHz, 15KHz, 30KHz etc., can also using the embodiment of the present invention synchronization signal burst collection
