Abstract
Embodiments of the present disclosure provide a sidelink channel configuration method, a terminal device, and a network device. The method includes determining, in a terminal device, that a second time domain symbol in a first sidelink channel is a first Demodulation Reference Signal (DMRS) time domain symbol, and a difference in symbol locations of two adjacent DMRS time domain symbols is N. The first sidelink channel occupies K time domain symbols, and K is a positive integer, where 1≤N<K.
Claims14
A method for sidelink channel configuration, comprising:
- receiving, in a terminal device, first configuration information sent from a network device by control channel signaling, wherein the first configuration information is used to indicate that a second time domain symbol in a first sidelink channel is a first Demodulation Reference Signal (DMRS) time domain symbol;
- and
- determining, in the terminal device, that the second time domain symbol in the first sidelink channel is the first DMRS time domain symbol, and a difference in symbol locations of two adjacent DMRS time domain symbols is N, wherein the first sidelink channel occupies K time domain symbols, and a value of K is a positive integer, 1≤N<K;
- wherein the method further comprises:
- receiving, in the terminal device, further configuration information sent from the network device, wherein the further configuration information is used to indicate first index information;
- and determining, in the terminal device, a first DMRS pattern according to the first index information and a first correspondence, wherein the first correspondence comprises a correspondence between index information and DMRS patterns, and the first DMRS pattern is the DMRS pattern for transmitting the first sidelink channel, and wherein the first correspondence is pre-configured to the terminal device.
A terminal device, comprising a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to cause the terminal device to:
- receive first configuration information sent from a network device by control channel signaling, wherein the first configuration information is used to indicate that a second time domain symbol in a first sidelink channel is a first Demodulation Reference Signal (DMRS) time domain symbol;
- and
- determine that the second time domain symbol in the first sidelink channel is the first DMRS time domain symbol, and a difference in symbol locations of two adjacent DMRS time domain symbols is N, wherein the first sidelink channel occupies K time domain symbols, and a value of K is a positive integer, where 1≤N<K;
- receive further configuration information sent from the network device, wherein the further configuration information is used to indicate first index information;
- and
- determine a first DMRS pattern according to the first index information and a first correspondence, wherein the first correspondence comprises a correspondence between index information and DMRS patterns, and the first DMRS pattern is the DMRS pattern for transmitting the first sidelink channel, and wherein the first correspondence is pre-configured to the terminal device.
