The information of the PDCCH of remaining system information RMSI and/or the information of PDSCH.In one embodiment, the embodiment of the present invention can be with
Whether the channel for first detecting the synchronizing signal block idle, then detect the RMSI PDCCH and/or PDSCH it is whether idle.
In other embodiment, the present invention, which implements, can also use other detection orderings to the channel of the synchronizing signal block and described
The PDCCH and/or PDSCH of RMSI is detected, and the embodiment of the present invention is to detecting the channel of the synchronizing signal block and detecting institute
The detection ordering for stating the PDCCH and/or PDSCH of RMSI is not specifically limited.
In one embodiment, the base station 21 to the channel of the synchronizing signal block and the PDCCH of RMSI and/
It, can be according to the running time-frequency resource position of the PDCCH of the corresponding RMSI of synchronizing signal block come really or before PDSCH is detected
Determine Channel Detection mechanism.Wherein, the PDCCH of the RMSI is for sending scheduling information, and the scheduling information is for informing user
The relevant informations such as the reception decoding of the PDSCH of equipment RMSI；And the PDSCH of the RMSI be used for send remaining system information to
Family equipment.
It should be noted that the time domain initial position of the PDCCH of the corresponding RMSI of the synchronizing signal block SSB is joined by configuration
Number O is determined.For example, SSB, the monitor window monitoring window of the PDCCH of corresponding RMSI that a number is i
It is for two continuous slot s lot, starting slotIt base station 21 can be at this
The information of the PDCCH of suitable position transmission RMSI and/or the information of PDSCH are chosen in monitoring window.Wherein,
Parameter O and M is provided by corresponding table, μ ∈ { 0,1,2,3 }, and the subcarrier spacing SCS subcarriers of the PDCCH based on RMSI
Interval,When to give SCS in one system-frame frame slot quantity, SCS determines by μ.
Therefore, base station 21 can be according to the configuration parameter O come the channel for determining the SSB and the RMSI
The Channel Detection mechanism of PDCCH.Wherein, the value of parameter O can be determined according to frequency range (frequency range, FR).Its
In, for FR1 (frequency range 1, i.e. 6GHz or less), parameter O values are { 0,2,5,7 }, for FR2
(frequency range 2, i.e. 6GHz or more), parameter O values are { 0,2.5,5,7.5 }.And parameter O determines RMSI's
The time domain of the monitoring window of PDCCH originates slot.For example, when O values are 0,2 (FR1) or 0,2.5 (FR2),
SSB is spaced smaller in the time domain with the information of the PDCCH of corresponding RMSI, and base station may be used in a variety of Channel Detection mechanism
Any one, the embodiment of the present invention using which kind of Channel Detection mechanism to being specifically not specifically limited.And in this case, it is right
The channel of the SSB carries out Channel Detection with the PDCCH of corresponding RMSI using the Channel Detection mechanism of joint-detection mode, can
Utmostly to ensure that base station can be after sending SSB, to the information of PDCCH in corresponding RMSI and/or the information of PDSCH
It can be successfully transmitted, and will not be accounted for because of channel is sent between the time-domain position of the information of SSB time-domain positions and the PDDCH
Excessive running time-frequency resource is wasted with signal.
In another example when O values are 5,7 (FR1) or 5,7.5 (FR2), SSB exists with the information of the PDCCH of corresponding RMSI
Be spaced in time domain it is larger, if using the Channel Detection testing mechanism of joint-detection to the PDCCH of the SSB and corresponding RMSI
More running time-frequency resource can be wasted by carrying out Channel Detection, at this moment can use to the channel of SSB and the PDCCH of corresponding RMSI into
The channel sensitive manner of row independent detection, and use different Channel Detection mechanism.Or channel and phase to SSB can also be used
The PDCCH of the RMSI answered carries out the channel sensitive manner of independent detection, uses identical channel detection method and the channel of the two
The associated Channel Detection mechanism of detection parameters.
It should be noted that the embodiment of the present invention is according to the information of the PDCCH of the corresponding RMSI of synchronizing signal block
Running time-frequency resource position determines that Channel Detection mechanism is one of which method of determination, and the embodiment of the present invention can also determine any one
Channel Detection mechanism is planted to carry out Channel Detection, the embodiment of the present invention is not specifically limited the determination of Channel Detection mechanism.By
Larger in NR bandwidth and with the characteristic of a variety of SCS configurations, when carrying out Channel Detection, used parameter is (priority, competing
Strive window, random number N, postpone phase defer period etc.) may need to be changed according to SCS used.
It needs further exist for illustrating, in a variety of Channel Detection mechanism mentioned in the embodiment of the present invention, has given tacit consent to RMSI
PDCCH information in the time domain always after corresponding SSB, in Channel Detection, always first whether detection SSB channels empty
Spare time, then detect RMSI PDCCH it is whether idle.This is because if base station detects that SSB does not send success, base station hair
The information of the information and/or PDSCH of sending corresponding PDCCH is also nonsensical.And in fact, in some cases, RMSI's
The information of PDCCH in the time domain may be before corresponding SSB, in this case, and the embodiment of the present invention can also make
With any one in a variety of Channel Detection mechanism provided in an embodiment of the present invention.For the embodiment of the present invention, base station can be first
The Channel Detection of PDSCH in similar LTE is carried out to the PDCCH of RMSI, the information of the information and/or PDSCH that wait for PDCCH has been sent
Cheng Hou continues to send channel occupancy signal, until sending corresponding SSB.

In one embodiment, base station can detect the letter of the synchronizing signal block using different Channel Detection mechanism
The PDCCH in road and the remaining system information.For example, the Channel Detection mechanism using PDSCH in LAA detects synchronizing signal block
Channel, use the DRS in the LAA Channel Detection mechanism detection remaining system information PDCCH.Certainly, in other realities
It applies in example, base station can also use other Channel Detection mechanism to believe the channel of the synchronizing signal block and the remaining system
The PDCCH of breath is detected.
S302：If the channel idle of the synchronizing signal block, the synchronizing signal block is sent to user equipment.
In the embodiment of the present invention, if detecting the channel idle of the synchronizing signal block, base station can be set to user
Preparation send the synchronizing signal block.In one embodiment, when the channel idle for detecting synchronizing signal block by associated form
When, base station can send the synchronizing signal block in the time-domain resource of the total bandwidth to the user equipment.In a reality
It applies in example, when detecting the channel idle of synchronizing signal block by independent mode, base station can be in the synchronizing signal block
In the time-domain resource of channel the synchronizing signal block is sent to the user equipment.
In one embodiment, when detecting the channel and RMSI for detecting the synchronizing signal block using united mode
When PDCCH, base station after sending the synchronizing signal block to user equipment, can the channel of the synchronizing signal block when
After the end position of domain and before the time domain initial position of the PDCCH of the remaining system information, in the synchronizing signal block

Resource location.
It should be noted that for the PDCCH and PDSCH of remaining system information, due to the frequency of PDCCH and PDSCH occupancy
Domain resource is identical and time domain is continuous, when detecting that the channel is in the idle state, in the remaining system information
The information of the PDCCH of the remaining system information is sent in the time-domain resource and frequency domain resource of PDCCH to the user equipment；
When completing to send the information of the PDCCH of the remaining system information, the PDSCH of the remaining system information time-domain resource and
The information of the PDSCH of the remaining system information is sent in frequency domain resource to the user equipment.In remaining system information
Before PDSCH is sent after PDCCH is sent completely, Channel Detection need not be carried out.
S303：The information of the PDCCH of RMSI and/or the information of PDSCH are sent to the user equipment.
In the embodiment of the present invention, after detecting that base station has sent the synchronizing signal block to user equipment, base station can
To send the information of the PDCCH of RMSI and/or the information of PDSCH to the user equipment.In one embodiment, when pass through connection
When conjunction detection mode detects the PDCCH free time of RMSI, base station can be in the time-domain resource of the total bandwidth to the user

When the PDCCH for the channel and RMSI for detecting the synchronizing signal block using independent mode, the synchronizing signal block
Channel Detection mechanism and the Channel Detection mechanism of the PDCCH of remaining system information differ, and the second channel of the PDCCH
The priority of testing mechanism higher than the first Channel Detection mechanism of the channel of the synchronizing signal block priority when, base station can be with
Detecting that the SSB is idle using low the first Channel Detection mechanism of priority, and after having sent the SSB, use is excellent
First grade detects the PDCCH of the remaining system information higher than the second channel testing mechanism of the first Channel Detection mechanism, such as
Fruit detects that the PDCCH of the remaining system information is idle, then base station can send the remaining system information to user equipment
PDCCH information.
For example, it is assumed that the synchronizing signal block uses LAA (Licensed Assisted Access authorize auxiliary access)
The Channel Detection mechanism of middle PDSCH, first, in accordance with the first detection granularity Detection channel status, wherein the first detection granularity can be with
The phase (defer period) is postponed for one, the duration of each defer period includes 16us+M*9us, if channel is in sky
Not busy state, then it is contention window value that random number N, wherein q are taken between 0~q.Then according to the second detection granularity Detection channel shape
State, the second detection granularity is 9us.If channel is in idle condition, N-1.If channel is in busy state, again according to first
Granularity Detection channel status is detected, if channel is in idle condition, random number N subtracts 1 again, and restores with the second detection granularity
Channel is detected, and so on, until N is kept to 0, then it represents that channel idle can send synchronizing signal block.It is actually using
In, the first detection granularity and the second detection granularity in the Channel Detection parameter of synchronizing signal block can be with the differences in LAA, can
To take smaller value.The PDCCH of remaining system information, which is used, finds reference signal (Discovery Signals, DRS) in LAA
Channel Detection mechanism, after sending synchronizing signal block, if detecting channel, there are the X us' of a short time (shot)
