S410. The network device determines indication information, where the indication information is used to indicate a frequency domain resource offset of the control resource and a frequency domain resource of the control resource, where the frequency domain resource offset of the control resource is a frequency relative to the synchronization signal. The offset of the domain resource.

The determining, by the network device, the indication information may include: the network device generating, configuring, storing, and/or pre-defining or receiving the indication information from another network.

An example of such a network device is network device 110.

The indication information may be an index indicating a frequency domain resource offset of the control resource and a frequency domain resource of the control resource.

S420. The network device sends the indication information. Accordingly, the terminal device receives the indication information.

An example of the terminal device is the terminal device 120.

S430. The terminal device receives the control resource according to the indication information.

In a first possible implementation manner, the channel bandwidth of the network device is 10 MHz, the subcarrier spacing of the PDCCH is 15 kHz, the synchronization signal grid is 3.6 MHz, and the number of resource blocks of the control resource is 48, that is, the channel The number of resource blocks of the bandwidth is 52, the number of resource blocks of the synchronization signal is 20, and the number of resource blocks of the control resource is 48. If one resource block is a unit of frequency domain position offset, the synchronization signal in the communication system The block (SS block, SSB) has a relative position in the frequency domain of 33 (ie 52-20+1) possibilities.

Since 52-48=4, there are at most five possibilities for the frequency domain position offset of each control resource. In addition, since the number of resource blocks of the synchronization signal grid is 20, the offset corresponding to the next synchronization signal grid can be applied to the case where the relative position exceeds 20 resource blocks.

It can be seen from the above analysis that only four kinds of frequency domain position offsets can be used to indicate the frequency domain position offset of the control resource. When the four frequency domain position offsets are arranged in order of magnitude, the adjacent two frequency domains are adjacent. The position offsets differ by 5 resource blocks. If the maximum frequency domain position offset of the four frequency domain position offsets is represented by X, the number of resource blocks of the four frequency domain position offsets can be expressed as (X, X-5, X-10). , X-15). For example, the number of resource blocks of the four frequency domain position offsets may be (28, 23, 28, 13).

In order to ensure that the resource block of the synchronization signal block is located in the resource block of the control resource, the number of resource blocks of the maximum frequency domain position offset of the four frequency domain position offsets may be greater than or equal to 15, and less than or equal to 28, that is, 15=<X<=28.

Wherein, in order to ensure that the resource blocks of the synchronization signal block are located as far as possible in the resource blocks of the remaining minimum system resource concentration portion, the number of resource blocks of the four frequency domain position offsets may be (22, 17, 12, 7); or The number of resource blocks of the four frequency domain position offsets may be (21, 16, 11, 6).

Optionally, the index value may also be used to indicate the number of current symbols of the control resource, and the number of current symbols of the control resource is 1 or 2 or 3.

In a second possible implementation manner, the network device has a channel bandwidth of 20 MHz, a PDCCH subcarrier spacing of 15 kHz, a synchronization signal grid of 3.6 MHz, and a control resource resource block of 96, that is, a network. The number of resource blocks of the channel bandwidth of the device is 106, the number of resource blocks of the synchronization signal is 20, and the number of resource blocks of the control resource is 96. If one resource block is a unit of frequency domain position offset, then the communication system is in the communication system. The frequency domain relative position of the sync signal block has a probability of 87 (ie, 106-20+1).

Since 106-96 = 10, there are at most 11 possibilities for the frequency domain position offset of each control resource. In addition, since the number of resource blocks of the synchronization signal grid is 20, the offset corresponding to the next synchronization signal grid can be applied to the case where the relative position exceeds 20 resource blocks.

It can be seen from the above analysis that only two types of frequency domain position offsets are needed to indicate the frequency domain position offset of the control resource. When the two frequency domain position offsets are arranged in order of magnitude, the two adjacent frequency domains are adjacent. The position offsets differ by 10 resource blocks or 11 resource blocks. If the maximum frequency domain position offset of the two frequency domain position offsets is represented by X, the number of resource blocks of the two frequency domain position offsets may be expressed as (X, X-10) or (X). , X-11).

When the two kinds of frequency domain position offsets differ by 10 resource blocks, an example of the number of resource blocks of the two frequency domain position offsets is (43, 33).

Wherein, in order to ensure that the resource block of the synchronization signal block is located in the resource block of the control resource, when the two kinds of frequency domain position offsets are different by 10 resource blocks, the maximum frequency domain among the two frequency domain position offsets The number of resource blocks of the position offset may be greater than or equal to 10 and less than or equal to 76, that is, 10=<X<=76; when the two types of frequency domain position offsets differ by 11 resource blocks, the two types The number of resource blocks of the maximum frequency domain position offset in the frequency domain position offset may be greater than or equal to 11, and less than or equal to 76, that is, 11=<X<=76.

Wherein, in order to ensure that the resource blocks of the synchronization signal block are located as far as possible in the resource blocks of the remaining minimum system resource concentration portion, when the two kinds of frequency domain position offsets differ by 10 resource blocks, the two frequency domain position offsets The difference between the two frequency domain position offsets is 11 (44, 33), or (43, 32). ).

Optionally, the index value is further used to indicate the number of current symbols of the control resource, and the number of current symbols of the control resource is 1 or 2 or 3.

In a third possible implementation manner, the channel bandwidth of the network device is 10 MHz, the subcarrier spacing of the PDCCH is 30 kHz, the synchronization signal grid is 3.6 MHz, and the number of resource blocks of the control resource is 24, that is, the network. The number of resource blocks of the channel bandwidth of the device is 24, the number of resource blocks of the synchronization signal is 10, and the number of resource blocks of the control resource is 24, and if one resource block is a unit of frequency domain position offset, then the communication system is in the communication system. The frequency domain position offset of each control resource has a maximum of 1 (24-24+1) possibilities. In addition, since the number of resource blocks of the sync signal grid is 10, the offset corresponding to the next sync signal grid can be applied to the case where the relative position exceeds 10 resource blocks.

It can be seen from the above analysis that only 10 kinds of frequency domain position offsets can be needed to indicate the frequency domain position offset of the control resource. When the 10 frequency domain position offsets are arranged in order of magnitude, the adjacent two frequency domains are adjacent. The position offsets differ by 1 resource block. If X is used, the maximum frequency domain position offset among the 10 frequency domain position offsets is represented. For example, the number of resource blocks of the 10 frequency domain position offsets may be (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) or (1, 2, 3, 4, 5, 6,7,8,9,10) or (2,3,4,5,6,7,8,9,10,11) or (3,4,5,6,7,8,9,10, 11,12) or (4,5,6,7,8,9,10,11,12,13) or (5,6,7,8,9,10,11,12,13,14).

Optionally, the index value may also be used to indicate the number of symbols currently used by the control resource, and the number of current symbols of the control resource is 2.

In a fourth possible implementation manner, the channel bandwidth of the network device is 20 MHz, the subcarrier spacing of the PDCCH is 30 kHz, the synchronization signal grid is 3.6 MHz, and the number of resource blocks of the control resource is 48, that is, the network The number of resource blocks of the channel bandwidth of the device is 51, the number of resource blocks of the synchronization signal is 10, and the number of resource blocks of the control resource is 48. If one resource block is a unit of frequency domain position offset, each control resource is used. The frequency domain position offset has a maximum of 4 (51-48+1) possibilities. In addition, since the number of resource blocks of the sync signal grid is 10, the offset corresponding to the next sync signal grid can be applied to the case where the relative position exceeds 10 resource blocks.

It can be seen from the above analysis that only three types of frequency domain position offsets can be used to indicate the frequency domain position offset of the control resource. When the three frequency domain position offsets are arranged in order of magnitude, the two adjacent frequency domains are arranged. The position offsets differ by 4 resource blocks.

If X is used to represent the maximum frequency domain position offset among the three frequency domain position offsets, the number of resource blocks of the two frequency domain position offsets can be expressed as (X, X+4, X+8). ). For example, the number of resource blocks of the three frequency domain position offsets may be (15, 19, 23) or (18, 22, 26).

Optionally, the index value is further used to indicate the number of current symbols of the control resource, and the number of current symbols of the control resource is 2 or 3.
