Abstract

Provided are a method for transmitting control information, which includes that: a terminal device determines a first synchronization raster from at least two synchronization rasters allowed in a channel bandwidth, and determine information of a control resource set based on the first synchronization raster. Another method for transmitting control information, an electronic device and a storage medium are also provided.

Claims (32)

1. A method for transmitting control information, comprising:

determining, by a terminal device, a first synchronization raster from at least two synchronization rasters allowed in a channel bandwidth; and

determining information of a control resource set based on the first synchronization raster,

wherein

the first synchronization raster is determined based on a physical cell identifier PCI) in a synchronization signal block (SSB) detected by the terminal device, wherein a modulo operation result obtained by performing a modulo operation on the PCI based on a number of the at least two synchronization rasters allowed in the channel bandwidth has a corresponding relationship with a serial number of the first synchronization raster.

2. The method of claim 1 , wherein the SSB comprises indication information configured to indicate a frequency position of the first synchronization raster.

3. The method of claim 1 , wherein determining the information of the control resource set based on the first synchronization raster comprises:

determining a frequency domain position of the control resource set based on a second resource block (RB) offset between a frequency corresponding to an SSB detected by the terminal device and a frequency corresponding to the first synchronization raster.

4. The method of claim 3 , wherein determining the frequency domain position of the control resource set based on the second RB offset between the frequency corresponding to the SSB detected by the terminal device and the frequency corresponding to the first synchronization raster comprises:

determining the frequency domain position of the control resource set based on the second RB offset and a first RB offset.

5. The method of claim 4 , wherein the first RB offset is determined based on master information block (MIB) information in the SSB detected by the terminal device.

6. A method for transmitting control information, comprising:

sending, by a network device, a synchronization signal block (SSB), the SSB being configured for a terminal device to determine a first synchronization raster from at least two synchronization rasters allowed in a channel bandwidth, and the first synchronization raster being configured to determine information of a control resource set,

wherein

the first synchronization raster is determined based on a physical cell identifier (PCI) in a synchronization signal block (SSB) detected by the terminal device, wherein a modulo operation result obtained by performing a modulo operation on the PCI based on a number of the at least two synchronization rasters allowed in the channel bandwidth has a corresponding relationship with a serial number of the first synchronization raster.

7. The method of claim 6 , wherein the SSB comprises indication information, the indication information being configured to indicate a frequency position of the first synchronization raster.

8. A network device, comprising:

a processor; and

a memory configured to store a computer program runnable on the processor,

wherein the processor is configured to perform the operations of the method for transmitting control information according to claim 6 .

9. The network device of claim 8 , wherein the SSB comprises indication information, the indication information being configured to indicate a frequency position of the first synchronization raster.

10. A terminal device, comprising:

a processor; and

a memory configured to store a computer program runnable on the processor,

wherein the processor is configured to determine a first synchronization raster from at least two synchronization rasters allowed in a channel bandwidth, and determine information of a control resource set based on the first synchronization raster,

wherein

the first synchronization raster is determined based on a physical cell identifier (PCI) in a synchronization signal block (SSB) detected by the terminal device, wherein a modulo operation result obtained by performing a modulo operation on the PCI based on a number of the at least two synchronization rasters allowed in the channel bandwidth has a corresponding relationship with a serial number of the first synchronization raster.

11. The terminal device of claim 10 , wherein the SSB comprises indication information configured to indicate a frequency position of the first synchronization raster.

12. The terminal device of claim 10 , wherein

the processor is configured to determine a frequency domain position of the control resource set based on a second resource block (RB) offset between a frequency corresponding to an SSB detected by the terminal device and a frequency corresponding to the first synchronization raster.

13. The terminal device of claim 12 , wherein the processor is configured to determine the frequency domain position of the control resource set based on the second RB offset and a first RB offset.

14. The terminal device of claim 13 , wherein the first RB offset is determined based on master information block (MIB) information in the SSB detected by the terminal device.
