Abstract
This disclosure provides a method for determining a communications system parameter, a method for indicating a communications system parameter, and devices thereof. The method for determining a communications system parameter includes: determining a communications system parameter based on obtained first indication information, and/or determining a communications system parameter based on a mapping relationship between an influencing factor of the communications system parameter and the communications system parameter, where the communications system parameter includes a subcarrier spacing of a sidelink channel, and the communications system parameter is used to decode information carried on the sidelink channel.
Claims20
A method for indicating a communications system parameter, performed by a transmit-end device, and comprising:
- determining a communications system parameter, wherein the communications system parameter is determined based on obtained second indication information, or determined based on a mapping relationship between an influencing factor of the communications system parameter and the communications system parameter, wherein the communications system parameter comprises a Subcarrier Spacing (SCS) of a sidelink channel;
- and
- transmitting first indication information to a receive-end device, wherein the first indication information is used to indicate the communications system parameter, and the communications system parameter is used by the receive-end device to decode information carried on the sidelink channel.
A transmit-end device, comprising:
- a processor;
- and
- a non-volatile memory communicatively coupled to the processor, the memory storing program instructions that, when executed by the processor, cause the processor to implement operations comprising:
- determining a communications system parameter, wherein the communications system parameter is determined based on obtained second indication information, or determined based on a mapping relationship between an influencing factor of the communications system parameter and the communications system parameter, wherein the communications system parameter comprises a Subcarrier Spacing (SCS) of a sidelink channel;
- and
- transmitting first indication information to a receive-end device, wherein the first indication information is used to indicate the communications system parameter, and the communications system parameter is used by the receive-end device to decode information carried on the sidelink channel.
A network-end device, comprising:
- a processor;
- and
- a non-volatile memory communicatively coupled to the processor, the memory storing program instructions that, when executed by the processor, cause the processor to implement operations comprising:
- determining a communications system parameter based on a mapping relationship between an influencing factor of the communications system parameter and the communications system parameter, wherein the communications system parameter comprises a SCS of a sidelink channel;
- and
- transmitting first indication information to a receive-end device, wherein the first indication information is used to indicate the communications system parameter, and the communications system parameter is used by the receive-end device to decode information carried on the sidelink channel.
