Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the present invention one
Section Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
Fig. 1 shows a kind of schematic flow chart of the transmission method of SSB provided in an embodiment of the present invention, the method for Fig. 1
It can be executed by base station, as shown in Figure 1, this method comprises:
Step 101 sends at least one SSB；Wherein, any of at least one described SSB SSB belongs to a SSB points
Group, the SSB in any one SSB grouping corresponds to a random access resource, when the number of at least one SSB is more than one
When, any of at least one described SSB SSB is different from the grouping of SSB belonging to other SSB, any one SSB grouping is equipped with default
Main SSB.
It will be appreciated that multiple SSB form a SSB grouping, a SSB is at most sent in each SSB grouping, and each
The corresponding a random access resource of SSB in SSB grouping.And base station sends at least one SSB, when at least one that base station is sent
When the number of SSB is more than one, any of at least one SSB SSB is different from the grouping of SSB belonging to other SSB.
Wherein, random access resource can refer to how many SSB is corresponding leading in random access opportunity RO and each RO
Code Preamble.
It illustratively, is from 0 to 63 there are when most 64 SSB, being 64 SSB configuration numbers.Every 4 can be divided into
One group, 16 groups altogether, i.e., first group of number is SSB#0~3, and second group of number is SSB#4~7, and the number of third group is
SSB#8~11 ... ..., the 16th group of number is SSB#60~63.
Then this step specifically can be achieved to be that base station is planned to which SSB group sent as unit of group, as base station plans to send
The first six group, the then information that the signaling for being used to refer to actually have sent which SSB that base station is sent is included may is that base station is sent
SSB#0, SSB#4, SSB#8, SSB#12, SSB#16, SSB#20.It is of course also possible to be the other information in every group, such as base station
Have sent SSB#2, SSB#5, SSB#10, SSB#14, SSB#18, SSB#21.
That is, base station is sent for every group.It include SSB#0, SSB#1, SSB#2, SSB# for first group
3, vertical arrangement on the time.So Channel Detection is carried out before the present SSB#0 sending time position of base station, if detection letter
Road is idle, then sends SSB#0, first group with regard to the end of transmission；If but SSB#0 detects channel busy before, continues to test, directly
Until channel until successfully transmitting a SSB in first group, or before detecting SSB#3 also hurries.In other words
It says, according to grouping, every group interior according to Channel Detection busy situation for base station, at most sends a SSB.
Above-mentioned example is continued to use, any one SSB for such as defaulting each group is main SSB, i.e. SSB#0, SSB#5, SSB#9 ...
SSB#63。
That is, can according to the actual situation any any one SSB chosen in every SSB grouping as main SSB.
The present invention forms a SSB grouping by multiple SSB, at most sends a SSB in each SSB grouping, and every
The corresponding a random access resource of SSB in a SSB grouping reduces random access money to improve the probability that is successfully transmitted of SSB
The waste of the waste in source, i.e. RO and lead code.Meanwhile the quantity of the corresponding random access resource of each SSB is improved, to improve
The chance that random access is sent improves random access and sends success rate.
Optionally, as one embodiment, the main SSB of the default is first number in affiliated SSB grouping
SSB。
Continue to use above-mentioned example, such as default each group first SSB be main SSB, i.e. SSB#0, SSB#4, SSB#8 ...,
That is SSB#4*n, n take 0~15 integer.
Illustratively, as user UE#1 has received SSB#1, then the user knows that be because SSB#0 does not send success,
The time-frequency code resource location of the corresponding random access channel PRACH of SSB#0 can be used in so SSB#1.
Illustratively, as user UE#2 has received SSB#13, then the user knows that being because SSB#12 is not sent into
Function, then the time-frequency code resource location of the corresponding PRACH of SSB#12 can be used in SSB#13.Meanwhile UE#2 needs to assume front
SSB#0, SSB#4, SSB#8 or these SSB are sent successfully with other SSB in group.So UE#2 receives oneself
To SSB#13 still come the 4th of 6 SSB of base station notice, must then when mapping the RO time-frequency code resource of oneself
After the time-frequency code resource for first reserving the SSB of front 3, oneself available running time-frequency resource code is just taken turns to.Even if truth may be
Group none SSB where SSB#8 is sent successfully, that UE#2 can not go to occupy SSB#8 for RO time-frequency code resource,
Because UE#2 exact can not know whether SSB#8 sends.
Therefore, the transmission method of SSB based on the embodiment of the present invention makes to send a SSB's in each SSB grouping
The probability of success increases, to greatly reduce the waste of RO time-frequency code resource.The SSB phase in each SSB grouping is also ensured simultaneously
When in having shared a RO time-frequency code resource, the corresponding RO time-frequency code resource of SSB each really sent in this way is also just very abundant,
Compared at least 16 RO SSB points all come with 64 SSB points of all RO, running time-frequency resource improves many times, causes random
It is successfully accessed probability and also increases many times.
Each SSB grouping by being equipped with the main SSB of default by the embodiment of the present invention, can be with so that base station is when sending SSB
It is sent according to the instruction of base station, what it is such as base station instruction is to be planned to send respective main SSB in several groupings, in order to visitor
User at the end of family is in the information for receiving base station transmission, it is known that base station has sent the SSB of which group, it is known that the running time-frequency resource etc. of RO
Position.

The embodiment of the present invention passes through the lead code Preamble for sending the corresponding SSB of random access resource, in order to client
User at end is in the information for receiving base station transmission, it is known that the corresponding preamble of how many SSB in each RO.
Optionally, as one embodiment, the grouping of SSB is predefined；Alternatively, the grouping of SSB is that base station configures for UE
's.
When it is UE configuration that the grouping of SSB, which is base station, the grouping of the SSB is based on following at least one parameter configuration
:
The continuously distributed situation of the quantity of wave beam, the number of the estimated SSB sent in base station, SSB time-domain position, fixed duration
And channel condition.
Wherein it is possible to be grouped according to the continuously distributed situation of SSB time-domain position, specifically: it is illustrative, such as
240KHz, 4 continuous SSB are one group；Or in 120KHz, 2 continuous SSB are one group.
Wherein it is possible to be grouped according to fixed duration, specifically: it is illustrative, as being one group in 1ms window.
Wherein it is possible to be grouped according to channel condition, specifically: it is illustrative, if channel condition is poor, then needing every
SSB number in SSB grouping is more more.
The embodiment of the present invention is by being predefined by the grouping of SSB, alternatively, the grouping of SSB is that base station configures for UE.When
When the grouping of SSB is that base station configures for UE, the grouping of SSB is based on following at least one parameter configuration: the quantity of wave beam, base
It stands and expects the continuously distributed situation of the number of the SSB sent, SSB time-domain position, fixed duration and channel condition.So that every SSB
Grouping sends the chance of a SSB more greatly a bit, so that the RO wasting of resources is more a little less.
