Downlink transfer.
It will limit the flexibility that carrier wave is disposed in NR system in view of the scheme that channel grid value in the prior art is 100kHz
The problem of, in NR system, channel grid value is also conceivable to be set as other values.
Possible realize of one kind is to set channel grid value to 5kHz, i.e. integral multiple of the centre frequency of carrier wave in 5kHz
On.Compared to the scheme that channel grid value is 100kHz, channel grid value is that the scheme of 5kHz is capable of providing more available frequencies
Rate position is used for the deployment of carrier wave.
But channel grid value is that the scheme of 5kHz has following problem.
Specifically, in NR system, the boundary of synchronization signal/Physical Broadcast Channel block frequency domain resource block and system are public
The boundary of resource block can be misaligned altogether, and terminal device can know synchronization signal/physical broadcast by the method for frequency search
The center and boundary of the frequency domain resource block of block of channels.In order to enable terminal device can obtain the boundary of system public resource block,
The special bit field notice terminal device synchronization signal/Physical Broadcast Channel block frequency is had in Physical Broadcast Channel block
The difference on the boundary on the boundary and system public resource block of domain resource block.In order to guarantee that synchronization signal/broadcast channel block carries
Wave is aligned with the subcarrier of system public resource block grid, to avoid synchronization signal/broadcast channel block and other downlink signals into
There is inter-sub-carrier interference when row frequency division multiplexing, which is usually the integral multiple namely integer height of subcarrier spacing
The corresponding frequency of carrier wave.And when using the channel grid value of 5kHz, it is notified in the special bit field of Physical Broadcast Channel block
Can be 0 to the difference of terminal, 1 ..., the corresponding frequency of 23 subcarriers.It is needed in Physical Broadcast Channel in this way using 5 ratios
Special field indicates the difference, so that the bit number that Physical Broadcast Channel occupies is more, terminal device is caused to receive object
Manage the performance decline of broadcast channel block.
In view of that should guarantee the flexibility of carrier wave deployment in NR system as much as possible, guarantee that terminal is set as much as possible again
For the reliability for receiving Physical Broadcast Channel, the channel grid value for using 10kHz is proposed in the embodiment of the present application, i.e., in carrier wave
Frequency of heart is merely able on the integral multiple of 10kHz.It should be noted that the centre frequency of carrier wave is also possible to the reference frequency of carrier wave
Rate does not limit the title of the frequency herein.
The scheme of the embodiment of the present application is described in detail with reference to the accompanying drawing.

Step 101, the network equipment are according to the channel grid value of 10kHz or the channel grid of the integral multiple for 10kHz, really
Determine the centre frequency of first carrier.
Step 102, the network equipment send downlink signal to terminal device on the first carrier.
Step 103, the terminal device receive the downlink signal of network equipment transmission on the first carrier.
Specifically, which can determine the first carrier by the detection to downlink synchronous signal.It can also be with
The first carrier is notified by ARFCN by the network equipment to give the terminal device.Absolute wireless channel is received for terminal device
For the implementation of number (absolute radio frequency channel number, ARFCN), which is needed
The centre frequency of the first carrier is determined by the ARFCN.
As shown in Fig. 2, the embodiment of the application uplink signal transmissions the following steps are included:
Step 201, the network equipment are according to the channel grid value of 10kHz or the channel grid of the integral multiple for 10kHz, really
The centre frequency of fixed second carrier wave.
Step 202, the terminal device determine second carrier wave.
For TDD system, which is also used for the downlink signal transmission of the network equipment, therefore, the terminal
Equipment determines second carrier wave, either the terminal device determines second carrier wave by the detection to downlink synchronous signal,
The information of second carrier wave can also be notified by ARFCN by the network equipment to give the terminal device.
For FDD system, which is used for uplink, second is carried this by ARFCN by the network equipment
The information of wave notifies to give the terminal device.
Step 203, the terminal device send uplink signal to the network equipment on second carrier wave.
Step 204, the network equipment receive the uplink signal on second carrier wave.
For above-mentioned channel grid value be 10kHz scheme, compared to channel grid value be 100kHz scheme for, energy
Deployment of more frequency locations for carrier wave is enough provided；For the scheme for being 5KHz compared to channel grid value, make
The possibility value for obtaining above-mentioned difference is less, to only need to indicate this using less bit field in Physical Broadcast Channel
Difference so that facilitating promotion terminal device receives the reliability of Physical Broadcast Channel, and improves system performance.Wherein, should
Difference can be the corresponding frequency of even number subcarrier, i.e., 0,2 ..., 22, to only need to use 4 in Physical Broadcast Channel
The field of bit indicates the difference.
