As shown in Fig. 3 (A), Fig. 3 (A) is the signal of the running time-frequency resource position of the first pattern provided by the embodiments of the present application Figure, wherein the time-domain resource position of synchronizing signal block and the physical downlink control channel PDCCH information of remaining system information and object The time-domain resource position for managing DSCH Downlink Shared Channel PDSCH information is entirely different, frequency domain resource position and the residue of synchronizing signal block The frequency domain resource position of the physical downlink control channel PDCCH information and Physical Downlink Shared Channel PDSCH information of system information There are laps.As shown in Fig. 3 (B), Fig. 3 (B) is the running time-frequency resource position of second of pattern provided by the embodiments of the present application Schematic diagram, the frequency domain resource position of synchronizing signal block and the physical downlink control channel PDCCH information of remaining system information and The frequency domain resource position of Physical Downlink Shared Channel PDSCH information is entirely different, the N number of resource block of the two frequency domain interval (Resource Block, RB), N are more than or equal to 0 and are less than or equal to 1；The time-domain resource position of synchronizing signal block and remaining system The physical downlink control channel PDCCH information of information and the frequency domain resource position of Physical Downlink Shared Channel PDSCH information exist Lap.As shown in Fig. 3 (C), Fig. 3 (C) is showing for the running time-frequency resource position of the third pattern provided by the embodiments of the present application Be intended to, wherein the frequency domain resource position of synchronizing signal block and the physical downlink control channel PDCCH information of remaining system information and The frequency domain resource position of Physical Downlink Shared Channel PDSCH information is different, the N number of resource block of the two frequency domain interval, and N is more than or equal to 0 And it is less than or equal to 1；The time domain initial position of synchronizing signal block and the physical downlink control channel PDCCH information of remaining system information Time domain initial position it is identical, and the Physical Downlink Control Channel of the time-domain resource position and remaining system information of synchronizing signal block PDCCH information is identical with the time-domain resource position of Physical Downlink Shared Channel PDSCH information.

S202, according to first running time-frequency resource position and/or second running time-frequency resource position, whether detection channel is located In idle state.Including following several situations：

The first situation, for the running time-frequency resource position of the running time-frequency resource position and the third pattern of second of pattern of the two It sets, due to the frequency domain resource position of synchronizing signal block and the physical downlink control channel PDCCH information of remaining system information and object The frequency domain resource position for managing DSCH Downlink Shared Channel PDSCH information is entirely different.It can be by independent mode in respective frequency domain band Channel Detection, the Channel Detection of the Channel Detection mechanism of synchronizing signal block and the PDCCH channels of remaining system information are carried out on width Mechanism is mutual indepedent.Including：Channel, the Yi Ji of the synchronizing signal block are detected in the frequency domain bandwidth of the synchronizing signal block The PDCCH channels of the remaining system information are detected in the frequency domain bandwidth of the PDCCH channels of the remaining system information.Specific packet Include following several optional modes：

The first optional mode, can use the first Channel Detection mechanism detect the synchronizing signal block channel, with And the PDCCH channels of the remaining system information are detected using second channel testing mechanism.

For example, synchronizing signal block finds ginseng using LAA (Licensed Assisted Access authorize auxiliary access) is middle The Channel Detection mechanism for examining signal (Discovery Signals, DRS), before sending synchronizing signal block, if detecting letter There are the idle periods of the X us of a short time (shot) in road, then send synchronizing signal block immediately.And remaining system information PDCCH uses the Channel Detection mechanism of PDSCH in LAA, detects channel status first, in accordance with the first granularity, wherein first Angle value can be one and postpone the phase (defer period), and the duration of each defer period includes 16us+M*9us, if letter Road is in idle condition, then it is contention window value that random number N, wherein q are taken between 0~q.Then it is detected according to the second granularity Channel status, the second granularity are 9us.If channel is in idle condition, N-1.If channel is in busy state, again according to First granularity detects channel status, if channel is in idle condition, random number N subtracts 1 again, and restores with the second granularity Channel is detected, and so on, until N is kept to 0, then it represents that channel idle can send PDCCH information.It is actually using In, the first granularity and the second granularity in the Channel Detection parameter of the PDCCH of remaining system information can in LAA not Together, smaller value can be taken.

Second of optional mode, can be detected using identical Channel Detection mechanism the channel of the synchronizing signal block with And the PDCCH channels of the remaining system information.For example, the Channel Detection mechanism using DRS in LAA detects synchronizing signal block The PDCCH channels of channel and the remaining system information, or synchronized using the Channel Detection mechanism detection of PDSCH in LAA The PDCCH channels of the channel of block and the remaining system information.

Further, the channel of the synchronizing signal block and the residue are being detected using identical Channel Detection mechanism When the PDCCH channels of system information, different detection parameters may be used to carry out Channel Detection.Wherein.Channel Detection parameter It may include the free time length of channel.First that the channel for the synchronizing signal block for needing to detect can be obtained respectively is idle Second free time length of duration and the PDCCH channels of the remaining system information；Institute is detected according to first free time length It states the channel of synchronizing signal block and detects the PDCCH channels of the remaining system information according to second free time length,.

For example, when both using the Channel Detection mechanism of DRS in LAA, for synchronizing signal block, it is only necessary to detect There are the idle periods of X us durations for channel, you can sends synchronizing signal block.For the PDCCH of remaining system information, need to detect There are the idle periods of Y us durations for PDCCH channels, you can sends the PDCCH information of remaining system information, wherein X is less than or equal to Y。

Further, the channel of the synchronizing signal block and the residue are being detected using identical Channel Detection mechanism When the PDCCH channels of system information, the priority of the channel of the synchronizing signal block and the remaining system information can be obtained PDCCH channels priority；According to the priority, the first Channel Detection parameter of the channel of the synchronizing signal block is configured With the second channel detection parameters of the PDCCH channels of the remaining system information；According to the first Channel Detection parameter detecting The channel of the synchronizing signal block and the PDCCH that the remaining system information is detected according to the second channel detection parameters Channel.Wherein, the first Channel Detection parameter is different from second channel detection parameters, and Channel Detection parameter can be PDSCH in LAA Channel Detection mechanism in M values, q values and detection granularity.

For example, when both using the Channel Detection mechanism of PDSCH in LAA, and the priority of synchronizing signal block is higher than The parameter of the PDCCH of remaining system information, the Channel Detection mechanism of synchronizing signal block make it be more easily detected channel idle. For the Channel Detection of parameter M and q than the PDCCH for remaining system information in the Channel Detection mechanism of synchronizing signal block M and q values in scheme parameters are smaller.

Further, the channel of the synchronizing signal block and the residue are being detected using identical Channel Detection mechanism When the PDCCH channels of system information, Channel Detection can also be carried out using identical detection parameters.

The second situation, for the running time-frequency resource position of the running time-frequency resource position and the third pattern of second of pattern, The PDCCH channels of the channel and the remaining system information of synchronizing signal block can be detected by associated form.Including：By institute State the frequency domain bandwidth of synchronizing signal block, the frequency domain bandwidth of the PDCCH channels of the remaining system information and the synchronizing signal Bandwidth granularity group between the channel of block and the PDCCH channels of the remaining system information combines as a bandwidth；Described Sets of bandwidths closes the PDCCH channels of the channel and the remaining system information that detect the synchronizing signal block.

Further, the priority of the channel of the synchronizing signal block and the remaining system information can be obtained The priority of PDCCH channels；When using identical Channel Detection mechanism, the corresponding letter of the lower channel of the priority is selected Road detection parameters detect the PDCCH channels of the channel and the remaining system information of the synchronizing signal block.

For example, synchronizing signal block and the PDCCH of remaining system information use identical Channel Detection mechanism, but residue system The priority of the PDCCH for information of uniting is relatively low, i.e. the PDCCH of remaining system information is not easy to detect channel idle, then will After the frequency domain bandwidth and bandwidth granularity of the two form a bandwidth combination, the letter of the PDCCH of remaining system information can be used Road detection parameters.For another example, synchronizing signal block and the PDCCH of remaining system information use different Channel Detection mechanism, synchronous letter Number block uses the Channel Detection mechanism of the DRS of similar LAA, and the PDCCH of remaining system information uses the PDSCH's of similar LAA Channel Detection mechanism can use surplus then after the frequency domain bandwidth of the two and bandwidth granularity are formed a bandwidth combination The Channel Detection mechanism of the PDSCH of the used similar LAA of the PDCCH of remaining system information.

The third situation, for the running time-frequency resource position of the running time-frequency resource position and the third pattern of second of pattern, by It is later than or is synchronized with the sending time point of the PDCCH channels of remaining system information in the sending time point of synchronizing signal block, therefore The PDCCH channels of the remaining system information can be detected first；Then the PDCCH channels of the remaining system information when The channel of the detection synchronizing signal block in preset time range before the resource of domain ensures that the two Channel Detection separately carries out, But there is contact.

For example, the PDCCH channels of remaining system information all use the channel of similar PDSCH in LAA to examine with synchronizing signal block Survey mechanism can select the PDCCH channels of remaining system information to use complete Channel Detection mechanism, detect remaining system Before the PDCCH channels of information are idle state, i.e. N is kept to detect the channel idle of synchronizing signal block in the X us before 0, Then show that the two is detected simultaneously by idle channel.

If it should be noted that due to the transmission without synchronizing signal block, the PDCCH of corresponding remaining system information is sent out It send just nonsensical.That is, if the Channel Detection of synchronizing signal block is unsuccessful, even if the PDCCH of remaining system information Channel Detection success also do not use.Therefore, for the running time-frequency resource position of second of pattern of the two, it should believe in remaining system Start the channel of detection synchronizing signal block before the time domain initial position of the PDCCH of breath, because if remaining system information PDCCH has begun to send, and the channel busy of synchronizing signal block is detected before the time domain initial position of synchronizing signal block, So the PDCCH of remaining system information sends just nonsensical.Certainly, it is originated in the time domain of the PDCCH of remaining system information When detecting the channel of synchronizing signal block before position, independent mode or associated form that can be more than use is to synchronizing signal block Channel and the PDCCH channels of remaining system information carry out Channel Detection.And for the running time-frequency resource position of the third pattern of the two, It is not limited since the starting of time domain initial position is identical.In conclusion in the PDCCH letters for sending remaining system information Before breath, it is necessary to which the PDCCH channels of the channel idle and remaining system information that detect synchronizing signal block are also idle, just can be with Send the PDCCH information of remaining system information.

S203, when detecting that the channel is in the idle state, to user equipment send the synchronizing signal block, Or the PDCCH information or PDSCH information of the remaining system information.

For the running time-frequency resource position of the third pattern, when detecting synchronizing signal by independent mode or associated form It, can be in the channel of the synchronizing signal block when PDCCH channel idles of the channel idle of block and the remaining system information In time-domain resource and frequency domain resource the synchronizing signal block is sent to the user equipment；And in the remaining system information The PDCCH information of the remaining system information is sent in the time-domain resource and frequency domain resource of PDCCH channels to the user equipment.

For the running time-frequency resource position of second of pattern, since the time domain initial position of synchronizing signal block is later than remaining system The time domain initial position of the PDCCH information of information, when the channel for detecting synchronizing signal block by associated form or independent mode It, can be in the time-domain resource of the channel of the synchronizing signal block when PDCCH channel idles of the idle and described remaining system information With in frequency domain resource the synchronizing signal block is sent to the user equipment；And believe in the PDCCH of the remaining system information The PDCCH information of the remaining system information is sent in the time-domain resource and frequency domain resource in road to the user equipment, and in institute State after the time domain initial positions of the PDCCH channels of remaining system information and the time domain initial position of the synchronizing signal block it Preceding that channel occupancy signal is sent in the frequency domain resource of synchronizing signal block, it is described same that the channel occupancy signal is used to indicate occupancy Walk the frequency domain resource position of block.

Further, for the PDCCH and PDSCH of remaining system information, the frequency domain money occupied due to PDCCH and PDSCH Source is identical and time domain is continuous, when detecting that the channel is in the idle state, in the remaining system information The PDCCH information of the remaining system information is sent in the time-domain resource and frequency domain resource of PDCCH channels to the user equipment； When completing to send the PDCCH information of the remaining system information, in the time domain money of the PDSCH channels of the remaining system information The PDSCH information of the remaining system information is sent on source and 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.

It should be noted that above all only to the time-frequency of the running time-frequency resource position and the third pattern of second of pattern of the two Resource location is described, and needs to carry out channel inspection using other schemes to the running time-frequency resource position of the first pattern It surveys, the embodiment of the present application is not described.

In the embodiment of the present application, it is first determined the first running time-frequency resource position of synchronizing signal block and remaining system letter The physical downlink control channel PDCCH information of breath and the second running time-frequency resource position of Physical Downlink Shared Channel PDSCH information；So Afterwards according to first running time-frequency resource position and/or second running time-frequency resource position, whether detection channel is in idle condition； Finally when detecting that the channel is in the idle state, the synchronizing signal block or described surplus is sent to user equipment The PDCCH information or PDSCH information of remaining system information improve information transmitting efficiency to improve the efficiency of channel access.

For example, synchronizing signal block uses DRS in LAA (Licensed Assisted Access authorize auxiliary access) Channel Detection mechanism, before sending synchronizing signal block, if detecting channel, there are the X us' of a short time (shot) Idle periods then send synchronizing signal block immediately.And the PDCCH of remaining system information uses the Channel Detection machine of PDSCH in LAA System detects channel status first, in accordance with the first granularity, wherein the first granularity can be a postponement phase (defer Period), the duration of each defer period includes 16us+M*9us, if channel is in idle condition, between 0~q It is contention window value to take random number N, wherein q.Then channel status is detected according to the second granularity, the second granularity is 9us.If Channel is in idle condition, then N-1.If channel is in busy state, channel status is detected again according to the first granularity, if letter Road is in idle condition, then random number N subtracts 1 again, and restores to detect channel with the second granularity, and and so on, until N It is kept to 0, then it represents that channel idle can send PDCCH information.In actual use, the channel of the PDCCH of remaining system information The first granularity and the second granularity in detection parameters can take smaller value with the difference in LAA.

Further, the channel of the synchronizing signal block and the residue are being detected using identical Channel Detection mechanism When the PDCCH channels of system information, different detection parameters may be used to carry out Channel Detection.Wherein.Channel Detection parameter It may include the free time length of channel.First that the channel for the synchronizing signal block for needing to detect can be obtained respectively is idle Second free time length of duration and the PDCCH channels of the remaining system information；Institute is detected according to first free time length It states the channel of synchronizing signal block and detects the PDCCH channels of the remaining system information according to second free time length.

The third situation, for the running time-frequency resource position of the running time-frequency resource position and the third pattern of second of pattern, by It is later than or is synchronized with the sending time point of the PDCCH channels of remaining system information in the sending time point of synchronizing signal block, therefore The PDCCH channels of the remaining system information can be detected；The remaining system information PDCCH channels time-domain resource it The channel of the detection synchronizing signal block in preceding preset time range ensures that the two Channel Detection separately carries out, but there is connection System.
