The mode of channel where frequency spectrum, the ability of channel detection equipment is made full use of to detect channel where unlicensed spectrum, improves inspection
Degree of testing the speed, the utilization rate of channel where improving unlicensed spectrum, so as to improve spectrum efficiency.
Refer to Fig. 2, Fig. 2 is the schematic flow sheet of another channel detection method provided in an embodiment of the present invention, the letter
Road detection method can be applied to channel detection equipment, and the channel detection equipment may include：Access network equipment or terminal device.Such as figure
Shown in 2, the channel detection method may include：
201st, the size of the supported maximum single carrier transmission bandwidth of channel detection equipment is determined；
202nd, above-mentioned channel detection equipment supported maximum single carrier transmission bandwidth be not less than pre-set bandwidths feelings
Under condition, determine that above-mentioned channel detection equipment is believed where detecting above-mentioned target spectrum as detection unit using the whole transmission bandwidth of system
Road；
203rd, it is less than the feelings of above-mentioned pre-set bandwidths in the supported maximum single carrier transmission bandwidth of above-mentioned channel detection equipment
Under condition, determine that above-mentioned channel detection equipment is believed where detecting above-mentioned target spectrum as detection unit using above-mentioned target transmission bandwidth
Road.
Specifically, above-mentioned target transmission bandwidth is the fractional bandwidth of the whole transmission bandwidth of system.
In the embodiment of the present invention, pre-set bandwidths can be set according to different communication systems, such as in NR, if maximum can
Transmission bandwidth is 400MHz, then the pre-set bandwidths can be 400MHz；Such as in enhanced long-period evolution system (Long Term
Evolution-Advanced, LTE-A) in, maximum transimissible bandwidth is 100MHz, then the pre-set bandwidths can be 100MHz
Deng；Each base station, eNB or gNB are such as directed to, pre-set bandwidths can be the maximum single carrier transmission bandwidth that the base station can be supported.
Specifically, the pre-set bandwidths can be the whole transmission bandwidth of system.
Specifically, the pre-set bandwidths can also be according to the different and different of channel detection equipment, that is to say, that the default band
It is wide to may include the first pre-set bandwidths and the second pre-set bandwidths, if the channel detection equipment is access network equipment, the pre-set bandwidths
For the first pre-set bandwidths, if the channel detection equipment is terminal device, the pre-set bandwidths can be second pre-set bandwidths etc..
For example, in lte-a system, pre-set bandwidths 100MHz, if channel detection equipment is base station, the base station passes
Have the ability to use this 100MHz as single carrier during defeated signal, then can determine that the base station can be on this whole 100MHz
Channel where detecting unlicensed spectrum.
Alternatively, in the case where the transmission bandwidth of above-mentioned channel detection equipment is not less than pre-set bandwidths, can also implement
Following methods, as determined, above-mentioned channel detection equipment detects above-mentioned target spectrum institute by detection unit of above-mentioned target transmission bandwidth
In channel etc., in the case that the embodiment of the present invention is not less than pre-set bandwidths for the transmission bandwidth of the channel detection equipment, the letter
Road detection device is specifically not construed as limiting for detection unit in which way.
That is, in the case where the transmission bandwidth of channel detection equipment is not less than pre-set bandwidths, the Channel Detection is set
It is standby the whole bandwidth of system to be divided into multiple single carriers to carry out Channel Detection respectively.For example, in LTE-A systems
In system, pre-set bandwidths 100MHz, if channel detection equipment is base station, the maximum transimissible bandwidth of the base station is 100MHz, then
This 100MHz can be divided into 5*20MHz by base station, so as to believe respectively on this five 20MHz where detection unlicensed spectrum
Road.
Alternatively, target transmission bandwidth includes：
Bandwidth belonging to carrier wave corresponding to carrier aggregation, and/or, preset bandwidth.
In the present embodiment, preset bandwidth can be that access network equipment and terminal device determine jointly in advance, that is to say, that
The access network equipment and terminal device have been reached common understanding.For example, if channel detection equipment wants the biography for reaching 100MHz
Defeated bandwidth, it is necessary to this 100MHz is can be only achieved by way of carrier aggregation, for example 100MHz is divided into 5 20MHz carrier wave,
The a width of 20MHz of the i.e. preset band or a width of 20MHz of band belonging to carrier wave, then the channel detection equipment can be corresponding to carrier aggregation
It is to detect channel where unlicensed spectrum on 20MHz respectively in bandwidth belonging to carrier wave or in preset bandwidth.
Again for example, in NR, band that base station and terminal device are pre-set is a width of to be divided into four by 400MHz
The a width of 100MHz of band belonging to 100MHz carrier wave, i.e., a width of 100MHz of preset band or carrier wave, then base station and terminal device can be with
Respectively in the bandwidth belonging to carrier wave corresponding to carrier aggregation or in preset bandwidth be 100MHz on detect unlicensed spectrum where
Channel.
It is understood that if base station and terminal device are reached common understanding, base station or terminal device can also gather in carrier wave
Channel Detection is carried out on the fractional bandwidth of carrier bandwidths corresponding to conjunction, such as carries out secondary division, will be each corresponding to carrier aggregation
Bandwidth belonging to carrier wave is divided again.If maximum transimissible bandwidth is 400MHz, 4 are divided into for the first time with a width of 100MHz
Carrier wave, and make it that it can not still be detected on this 100MHz non-for the transmittability of the channel detection equipment (such as terminal device)
Frequency spectrum place channel, such as the supported maximum a width of 50MHz of single carrier band of terminal device are authorized, then base where the terminal device
The 100MHz can also be separated into some bandwidth by standing, and such as be further divided into 2 50MHz, then and preset bandwidth is 50MHz,
Base station is by preset band width configuration to terminal, then the terminal device can detect unauthorized in the preset bandwidth on 50MHz
Channel where frequency spectrum.
In the present embodiment, preset bandwidth can also be the supported maximum single carrier transmission bandwidth of channel detection equipment.Lift
For example, the transmission bandwidth of system is 400MHz, and the maximum a width of 200MHz of single carrier band that base station or terminal device can be supported,
So base station or terminal can detect channel where the unlicensed spectrum with 200MHz preset bandwidth；If 400MHz points are
4 100MHz carrier wave, base station or terminal can also detect 1 or 2 100MHz carrier wave with 100MHz, to detect this
Channel where unlicensed spectrum.
Alternatively, in the case where the transmission bandwidth of above-mentioned channel detection equipment is not less than pre-set bandwidths, above-mentioned channel inspection
The priority of channel can be more than where measurement equipment detects above-mentioned target spectrum using the whole transmission bandwidth of system as detection unit
Channel where above-mentioned channel detection equipment detects above-mentioned target spectrum using target transmission bandwidth as detection unit, i.e. detection unit are got over
Greatly, priority is bigger.
The channel where above-mentioned channel detection equipment detects above-mentioned target spectrum using target transmission bandwidth as detection unit
In the case of, channel is preferential where above-mentioned channel detection equipment detects above-mentioned target spectrum using target transmission bandwidth as detection unit
Level can be more than above-mentioned channel detection equipment and detect above-mentioned target by detection unit of the fractional bandwidth of above-mentioned target transmission bandwidth
Channel where frequency spectrum.
Implement the present embodiment, determine detection mode according to different priority, channel detection equipment can be caused in energy
When power is stronger, there can be certain selecting sequence, improve the efficiency of channel detection equipment.
The specific implementation of the embodiment of the present invention can be with the implementation described by reference chart 1, here no longer one by one
It is described in detail.
Implement the embodiment of the present invention, channel detection equipment can be caused according to the ability of oneself to detect unlicensed spectrum institute
In channel, improve the speed of channel detection equipment detection, effectively reduce due to detection time is long and caused by propagation delay time,
Improve spectrum efficiency.
After channel detection equipment determines that it detects the mode of channel where target spectrum, and detecting the target
After channel where frequency spectrum, then channel where taking the target spectrum is needed, therefore, the embodiment of the present invention additionally provides one kind such as
The method of channel where what takes the target spectrum, refers to Fig. 3, and Fig. 3 is another channel inspection provided in an embodiment of the present invention
The schematic flow sheet of survey method, the channel detection method can be applied to the channel detection equipment described by previous embodiment, such as Fig. 3
Shown, the channel detection method may include：
301st, target power is obtained, above-mentioned target power is the work(of channel where the target spectrum in above-mentioned detection unit
Rate；
It is understood that the embodiment of the present invention is not construed as limiting for obtaining the method for target power.Such as in Channel Detection
When equipment is access network equipment, the energy where the target spectrum can be received using the receiver of the access network equipment on channel
Amount, so as to obtain target power；When channel detection equipment is terminal device, the receiver of terminal device can be utilized to receive and be somebody's turn to do
Energy where target spectrum on channel, so as to obtain target power.
Specifically, target power is the power of channel where the target spectrum in detection unit, if detection unit is system
Whole transmission bandwidth when, then the target power for system whole transmission bandwidth on target spectrum where channel power；
When the detection unit is target transmission bandwidth, the target power is the work(of channel where the target spectrum in the target transmission bandwidth
Rate.If more specifically, the target transmission bandwidth comprises at least two target transmission bandwidths, such as include the first transmission bandwidth and second
During transmission bandwidth, the target power is the power and the second transmission belt of channel where the target spectrum on the first transmission bandwidth respectively
Power of channel, etc. where target spectrum on width.
302nd, whether more than predetermined power determine above-mentioned channel detection equipment in above-mentioned detection list according to above-mentioned target power
The scope of transmission power where target spectrum in member on channel.
Specifically, when detection unit is different, predetermined power is different, and the bandwidth of detection unit is bigger, then predetermined power
It is bigger.It is pre- when predetermined power when being the whole transmission bandwidth of system such as detection unit with detection unit is target transmission bandwidth
If power is different, and predetermined power when detection unit is the whole transmission bandwidth of system is object transmission band more than detection unit
Predetermined power when wide.
Specifically, it is above-mentioned whether more than predetermined power to determine above-mentioned channel detection equipment above-mentioned according to above-mentioned target power
The scope of transmission power where target spectrum in detection unit on channel includes：
In the case where above-mentioned target power is more than above-mentioned predetermined power, determine above-mentioned channel detection equipment in above-mentioned detection
The scope of transmission power where target spectrum on unit on channel is not higher than the first power；
In the case where above-mentioned target power is not more than above-mentioned predetermined power, determine above-mentioned channel detection equipment in above-mentioned inspection
The scope of transmission power where surveying the target spectrum on unit on channel is not higher than the second power；Wherein, above-mentioned first work(
Rate is less than above-mentioned second power, and above-mentioned first power is more than or equal to 0, above-mentioned first power and above-mentioned second power be respectively less than or
Equal to the maximum transmission power of above-mentioned channel detection equipment.
In the embodiment of the present invention, emission maximum work(that maximum transmission power be able to can be launched for channel detection equipment in itself
When rate such as the channel detection equipment is terminal device, the maximum transmission power of the terminal device can be 23dBm.And in honeycomb
In system, to prevent monkey chatter and near-far interference, it is therefore desirable to carry out power to the transmission power of access network equipment such as base station
Control.Therefore, maximum transmission power can also be that channel detection equipment such as access network equipment or terminal are set in the embodiment of the present invention
The standby maximum transmission power that can launch after Power Control, as terminal device by the maximum transmission power of itself is
23dBm, and to it after Power Control, its maximum transmission power may only have 22dBm.Therefore, in the embodiment of the present invention, most
Big transmission power may include the maximum transmission power that channel detection equipment can launch in itself, may also comprise channel detection equipment warp
The maximum transmission power that can launch after overpower control.
In actual applications, the transmission power of access network equipment such as base station can be 43dBm, and the transmission power of terminal device
Can be 23dBm, therefore, in the embodiment of the present invention, the first power and the second power can according to channel detection equipment difference and
It is different.When such as the channel detection equipment is terminal device, first power can be 20dBm, and second power can be
23dBm；When the channel detection equipment is access network equipment, first power can be 40dBm, and second power can be
43dBm。
It is understood that the value of the first power and the second power can also be different according to detection unit, such as detect
The first power when the first power and detection unit when unit is the whole transmission bandwidth of system are target transmission bandwidth can be with
Difference, when the second power when detection unit is the whole transmission bandwidth of system can also be target transmission bandwidth with detection unit
