Abstract
Disclosed by the embodiment of the present application are a method for transmitting data in the Internet of Vehicles, a terminal device and a network device, the method comprising: a terminal device determining a demodulation reference signal (DMRS) pattern corresponding to a first channel; and the terminal device demodulating the first channel according to the DMRS pattern.
Claims9
A method for transmitting data, comprising:
- determining, by a terminal device, a plurality of demodulation reference signal (DMRS) patterns corresponding to a physical sidelink shared channel (PSSCH) according to a resource pool, among a plurality of resource pools, used by the PSSCH and a correspondence between the resource pool and the plurality of DMRS patterns;
- determining, by the terminal device from the plurality of DMRS patterns, a DMRS pattern used for demodulating the PSSCH according to indication information carried by a physical sidelink control channel (PSCCH) corresponding to the PSSCH;
- and
- demodulating, by the terminal device, the PSSCH according to the DMRS pattern,
- wherein the DMRS pattern comprises a number and a position of an orthogonal frequency division multiplexing (OFDM) symbol occupied by DMRS within one time unit.
A terminal device, comprising a processor and a memory, wherein the memory is configured to store instructions, and the processor, when executing the instructions stored in the memory, is configured to:
- determine a plurality of demodulation reference signal (DMRS) patterns corresponding to a physical sidelink shared channel (PSSCH) according to a resource pool, among a plurality of resource pools, used by the PSSCH and a correspondence between the resource pool and the plurality of DMRS patterns;
- determine, from the plurality of DMRS patterns, a DMRS pattern used for demodulating the PSSCH according to indication information carried by a physical sidelink control channel (PSCCH) corresponding to the PSSCH;
- and
- demodulate the PSSCH according to the DMRS pattern,
- wherein the DMRS pattern comprises a number and a position of an orthogonal frequency division multiplexing (OFDM) symbol occupied by DMRS within one time unit.
A network device, comprising a processor and a memory, wherein the memory is configured to store instructions, and the processor, when executing the instructions stored in the memory, is configured to:
- determine configuration information, wherein the configuration information is used by a terminal device to determine a plurality of demodulation reference signal (DMRS) patterns corresponding to a physical sidelink shared channel (PSSCH) according to a resource pool, among a plurality of resource pools, used by the PSSCH and a correspondence between the resource pool and the plurality of DMRS patterns, and determine, from the plurality of DMRS patterns, a DMRS pattern used for demodulating the PSSCH according to indication information carried by a physical sidelink control channel (PSCCH) corresponding to the PSSCH;
- and
- send the configuration information to the terminal device,
- wherein the DMRS pattern comprises a number and a position of an orthogonal frequency division multiplexing (OFDM) symbol occupied by DMRS within one time unit.
