Specific implementation mode
In 5G systems, primary synchronization signal (Primary Synchronization Signal, PSS), SSS
(Secondary Synchronization Signal, SSS) and Physical Broadcast Channel (Physical Broadcast
Channel, PBCH) it is included in synchronizing signal block (SS-block).On analog domain, each synchronizing signal block can be regarded as
The resource of a wave beam during beam scanning (Beam Sweeping).Multiple synchronizing signal blocks form a synchronizing signal
Happen suddenly (SS-burst) resource, and synchronizing signal burst resource can be regarded as sweeping the money that multiple wave beams are sent in turn in wave beam
Source.Multiple synchronizing signal burst resources form a synchronizing signal burst set (SS-burst-set).Synchronizing signal burst collection
Conjunction can be regarded as the decodable full resources of PBCH.The period of synchronizing signal burst set is exactly between the PBCH decodable times
Every the i.e. Transmission Time Interval of PBCH.
The concept of some broadcast type channels and signal is introduced in 5G systems.Broadcast type signal includes PSS and SSS
Deng the channel of broadcast type includes：PBCH, common control channel and the second Physical Broadcast Channel (sPBCH).
In detail, in 5G systems, the system information of broadcast is divided into two classes, and one kind is minimum system information
(Minimum System Information, MSI), another kind of is other systems information (Other System
Information, OSI).MSI is sent to user equipment by way of broadcast, and OSI generally asks unicast again by user
Mode be sent to user equipment.Therefore, only MSI could be sent in PBCH.Also, PBCH is generally limited to number of resources and leads
The bit number of enable carrying is less, 24 bits of carrying is only capable of in LTE system, therefore only part MSI can be in PBCH
Middle transmission.
Remaining MSI can be sent by two ways, and one is define a new broadcast channel, such as the second object
Broadcast channel (Secondary Physical Broadcast Channel, sPBCH) is managed, is sent on sPBCH remaining
MSI.Another kind is to be scheduled for physical data channel, is also known as sent on Physical Shared Channel (PDSCH).When using second of side
When formula, the channel for dispatching remaining MSI is also to send in a broadcast manner, that is, is carried on the channel of some broadcast type.
The channel of this broadcast type can be the control channel of certain broadcast type, can also be one of down control channel and public search
Rope space (Common Search Space, CSS), our referred to as common control channel.
Common control channel, can be with scheduling paging message (paging) other than it can dispatch remaining MSI.It is worth note
Meaning, 5G systems may only define common control channel, and MSI remaining in this way and paging message are all in common control channel
Transmission, it is also possible to while defining common control channel and sPBCH, then remaining MSI is transmitted in sPBCH, and paging message exists
It is transmitted in common control channel.
Due to these concepts of the synchronizing signal block introduced in 5G systems, their resource location how is configured, especially
It is how to configure the resource location of the synchronizing signal block including PSS, SSS and PBCH, finally to realize between base station and user equipment
Transmission to synchronizing signal block, has become urgent problem to be solved.
To solve the above problems, the base station in the embodiment of the present invention configures in synchronizing signal block occupied by each particular content
Symbolic number transmit the synchronizing signal block to user equipment, then user equipment can be according to current then in maximum bandwidth
Stage of communication and own type determine the frequency domain position of synchronizing signal block, that is, the bandwidth corresponding to synchronizing signal block,
And then the synchronizing signal block, and the symbolic number occupied by particular content in synchronizing signal block are received in the bandwidth,
It determines the resource location residing for each particular content in the synchronizing signal, therefore the transmission of synchronizing signal block may be implemented.And
Since user equipment can determine the bandwidth received with self-condition, the flexibility of synchronizing signal block configuration can also be improved.
To make the above purposes, features and advantages of the invention more obvious and understandable, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
Fig. 1 shows a kind of flow diagram of the transmission method of synchronizing signal block in the embodiment of the present invention, joins below
It examines Fig. 1 the method is discussed in detail step by step, the method can be implemented with following steps：
Step S11：According to the multiplexed situation of the synchronizing signal block and common control channel, sign resources quantity and institute
The particular content for stating synchronizing signal block configures the symbolic number occupied by particular content described in the synchronizing signal block.
In order to enable user equipment can parse after receiving synchronizing signal block and obtain the resource of each particular content
Position, in specific implementation, base station can be according to multiplexed situation, the sign resources of the synchronizing signal block and common control channel
The particular content of quantity and the synchronizing signal block, to configure the symbol occupied by particular content described in the synchronizing signal block
Number.
In specific implementation, base station can also configure the common control channel and occupy a symbol.In other words, for when
Domain resource location, if common control channel in synchronizing signal block, can configure common control channel and occupy a symbol.
In an embodiment of the present invention, it is 7 that common control channel and synchronizing signal block, which account for the sign resources quantity,.And
And the sign resources quantity shared by synchronizing signal block can be 7 or 6.It should be noted that herein with common control channel and
The sign resources quantity that synchronizing signal block accounts for jointly is to synchronize symbolic number shared by particular content in block based on 7
Configuration.
In specific implementation, the configuration about the symbolic number of the particular content of synchronizing signal block, base station can configure first
The synchronizing signal PSS in the block occupies a symbol, then according to the multiplexing of the synchronizing signal block and common control channel
The particular content of situation and the synchronizing signal block configures the symbol occupied by other particular contents in the synchronizing signal block
Number.
Specifically, when the common control channel and synchronizing signal block are time-multiplexed, that is, same band is occupied, but make
With different symbols.Common control channel occupies a symbol before synchronizing signal block.Synchronizing signal block can take up 6 symbols
Number.If further include in synchronizing signal block have extension synchronizing signal (Extended Synchronization Signal,
ESS), index values of the ESS for indicating synchronizing signal block in beam scanning, so that user equipment can detect the wave beam institute
Corresponding timing information can then be configured according to any one mode in following three kinds of modes.
Specifically, first way, which is the configuration synchronizing signal SSS in the block, occupies 1 symbol, the synchronization of extension
Signal occupies 1 symbol, and Physical Broadcast Channel occupies 3 symbols.The second way is the configuration synchronizing signal SSS in the block
2 symbols are occupied, the synchronizing signal of extension occupies 1 symbol, and Physical Broadcast Channel occupies 2 symbols.The third mode is to match
It sets synchronizing signal SSS in the block and occupies 1 symbol, the synchronizing signal of extension occupies 2 symbols, and Physical Broadcast Channel occupies
2 symbols.Wherein：The synchronizing signal of the extension is suitable for indicating the index value of affiliated synchronizing signal block in beam scanning.
It, can when the common control channel and synchronizing signal block are time-multiplexed, and when not including ESS in synchronizing signal block
1 symbol is occupied to configure the SSS, the Physical Broadcast Channel occupies 4 symbols, or the configuration SSS occupies 2 symbols
Number, the Physical Broadcast Channel occupies 3 signals.
In specific implementation, the SSS, ESS, the demodulated reference signal of Physical Broadcast Channel, the second Physical Broadcast Channel
Demodulated reference signal and the demodulated reference signal of common control channel be adapted to the Time and Frequency Synchronization of user equipment.
In specific implementation, if the common control channel and the non-time division multiplexing of synchronizing signal block, and synchronizing signal
Further include that can configure the synchronous letter when being useful for indicating the ESS of the index value of synchronizing signal block in beam scanning in block
Number SSS in the block occupies 1 symbol, and ESS occupies 1 symbol, and Physical Broadcast Channel occupies 4 symbols, or configuration is described same
Step signal SSS in the block occupies 2 symbols, and ESS occupies 1 symbol, and Physical Broadcast Channel occupies 3 symbols, or configuration institute
It states synchronizing signal SSS in the block and occupies 1 symbol, ESS occupies 2 symbols, and Physical Broadcast Channel occupies 3 symbols.
In specific implementation, if the common control channel and the non-time division multiplexing of synchronizing signal block, and synchronizing signal
When not including ESS in block, synchronizing signal SSS in the block can be configured and occupy 1 symbol, Physical Broadcast Channel occupies 5
Symbol, or the configuration synchronizing signal SSS in the block occupy 2 symbols, and Physical Broadcast Channel occupies 4 symbols, Huo Zhepei
It sets synchronizing signal SSS in the block and occupies 3 symbols, Physical Broadcast Channel occupies 3 symbols.
Step S12：In maximum bandwidth, the synchronizing signal block is transmitted to user equipment.
In specific implementation, the maximum bandwidth carries out quickly synchronous and measures when institute for non-bandwidth limited users equipment
The bandwidth used.Maximum bandwidth is also the transmitted bandwidth of synchronizing signal block, is that systemic presupposition is set and gives synchronizing signal block.For example,
The synchronizing signal block of 15kHz subcarrier spacings, may be used the maximum bandwidth of 5MHz, include the primary bandwidth of 4 1.4MHz.Again
For example, the synchronizing signal block of 60kHz subcarrier spacings, may be used the maximum bandwidth of 20MHz, include the basic band of 4 5MHz
It is wide.
In specific implementation, about in maximum bandwidth, transmitting the synchronizing signal block to user equipment, can there are many
Mode.
In an embodiment of the present invention, N times of corresponding subcarrier spacing before the synchronizing signal block may be used
Subcarrier spacing, and utilize the maximum bandwidth, transmit the synchronizing signal block.Wherein：N is positive integer.
Specifically, as N=1, that is, base station sends synchronizing signal block, non-bandwidth limited users in maximum bandwidth
Equipment receives synchronizing signal block directly in maximum bandwidth.When N is positive integer more than 1, N times of the subcarrier spacing in base station
The corresponding synchronizing signal block of original subcarrier spacing is sent, the bandwidth of such synchronizing signal block naturally becomes original N times.Example
It is such as originally the synchronizing signal block of 15kHz subcarrier spacings, occupies bandwidth 1.4MHz, base station is sent out with 60kHz subcarrier spacings
It send, the bandwidth that synchronizing signal block occupies becomes 5MHz.Therefore, can not have to be that 60kH subcarriers design synchronizing signal again in this way
Sequence is easy to forward compatibility.
In specific implementation, for the frequency domain position angle of synchronizing signal block, what is transmitted in the maximum bandwidth is same
Walk the removable synchronizing signal block being divided on multiple primary bandwidths of block.In other words, " broadband " synchronizing signal in maximum bandwidth
Block can split into " narrowband " synchronizing signal block on multiple primary bandwidths, for example broadband PSS, SSS and PBCH can be in frequencies
On split into correspondence PSS, SSS and PBCH of multiple narrowbands.
It should be noted that there are one primary bandwidths for synchronizing signal block tool, this primary bandwidth is that Bandwidth-Constrained user sets
Standby (Bandwidth-limited UE) can complete the minimum bandwidth being initially accessed.For example, the synchronization of 15kHz subcarrier spacings
The primary bandwidth of 1.4MHz may be used in block, occupies 72 subcarriers, i.e. 6 Physical Resource Block (Physical
Resource Block, PRB).
In specific implementation, the maximum bandwidth may include multiple primary bandwidths.Maximum bandwidth can be split into more
A primary bandwidth, such as the maximum bandwidth of 5MHz occupy 24 resource blocks, occupy 288 subcarriers in total, can split into 4
The primary bandwidth of 1.4MHz, each primary bandwidth occupy 72 subcarriers.
In specific implementation, multiple continuous primary bandwidths form a maximum bandwidth.Such as each primary bandwidth
72 subcarriers are occupied, the primary bandwidth of 4 1.4MHz forms the maximum bandwidth of a 5MHz, occupies 24 resource blocks, in total
Occupy 288 subcarriers.
Under the premise of maximum bandwidth may include multiple primary bandwidths, believe about the synchronization in maximum bandwidth, is transmitted
Number block is to user equipment, in an alternative embodiment of the invention, it is also an option that a primary bandwidth in the maximum bandwidth, passes
The defeated synchronizing signal block, and due to there is multiple primary bandwidths in maximum bandwidth, so when user equipment is in some primary bandwidth
