Data transmission method, terminal device, network device, and computer storage medium
View Patent ↗Disclosed in the present invention are a data transmission method, a terminal device, a network device and a computer storage medium. The method includes: determining, by the terminal device, a transmission waveform used by a first channel; and performing, by the terminal device, data transmission on the first channel according to the transmission waveform.
1. A data transmission method, comprising:
determining, by a terminal device, a transmission waveform of a first channel according to a second channel; and
performing, by the terminal device, data transmission on the first channel according to the transmission waveform;
wherein the first channel is a physical sidelink shared channel (PSSCH), and second channel is a physical sidelink control channel (PSCCH);
wherein determining, by the terminal device, the transmission waveform of the first channel according to the second channel comprises:
determining, by the terminal device, the transmission waveform of the first channel according to a correspondence relationship and a sequence of demodulation reference signal (DMRS) corresponding to the second channel, wherein the correspondence relationship is a correspondence relationship between a plurality of transmission waveforms and a plurality of sequences of DMRS.
2. The method of claim 1 , wherein the correspondence relationship is preconfigured on the terminal device or configured by a network device.
3. A terminal device, comprising a processor and a network interface, wherein
the processor is configured to determine a transmission waveform of a first channel according to a second channel; and
the network interface is configured to perform data transmission on the first channel according to the transmission waveform;
wherein the first channel is a physical sidelink shared channel (PSSCH), and second channel is a physical sidelink control channel (PSCCH);
wherein the processor is configured to determine the transmission waveform of the first channel according to a correspondence relationship and a sequence of demodulation reference signal (DMRS) corresponding to the second channel, wherein the correspondence relationship is a correspondence relationship between a plurality of transmission waveforms and a plurality of sequences of DMRS.
4. The method of claim 1 , wherein the correspondence relationship is preconfigured on the terminal device or configured by a network device.
