Title:
INFORMATION SENDING AND RECEIVING METHODS, DEVICE AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/052380
Kind Code:
A1
Abstract:
Information sending and receiving methods, a device and an apparatus. The information sending method comprises: a first terminal device determining, according to first information, at least one of the number or positions of m DMRSs carried on a PSSCH, m being a positive integer, the first information including at least one of a subcarrier interval, the duration of the PSSCH, or a channel coherence time, and the first terminal device sending the m DMRSs to a second terminal device. Provided is a scheme of configuring DMRS in a PSSCH of V2X in an NR system. Furthermore, a reference channel coherence time may be selected when determining DMRS in a PSSCH, for example, the time interval between two configured adjacent DMRSs may be made less than or equal to the channel coherence time, thereby improving the accuracy of channel estimation performed according to the DMRS.
