Abstract: A measurement parameter sending method and apparatus are described. The method includes receiving measurement signals corresponding to a plurality of beams. The received measurement signals corresponding to the plurality of beams are measured to obtain a beam measurement parameter. A cell-level measurement parameter is generated based on the beam measurement parameter. The cell-level measurement parameter is reported to a network device. Correspondingly, a measurement parameter receiving method and apparatus are disclosed. Measurement reporting of a plurality of beams can be implemented in a new radio NR system, thereby reducing reporting overheads.

Abstract: An information sending method, an information receiving method, a device, and an apparatus are disclosed. The information sending method includes: determining, by a first terminal device based on first information, at least one of a quantity or a position of m DMRSs carried on a PSSCH, where m is a positive integer, and the first information includes at least one of a subcarrier spacing, duration of the PSSCH, or a channel coherence time; and sending, by the first terminal device, the m DMRSs to a second terminal device. In addition, when the DMRS on the PSSCH is determined, a reference channel coherence time may be selected. For example, a time interval between two configured adjacent DMRSs may be less than or equal to the channel coherence time.

Abstract: A first terminal device determines a transmit power of a data channel, wherein the transmit power of the data channel comprise a first data channel part and a transmit power of a second data channel part, where the first data channel part is a part of the data channel that has a same time domain resource with a control channel, and the second data channel part is another part of the data channel that has a different time domain resource with the control channel. The first terminal device sends data in the first data channel part at the transmit power of the first data channel part, and sends data in the second data channel part at the transmit power of the second data channel part. This application may be applied to internet of vehicles, for example, V2X, LTE-V, and V2V.

Abstract: This application provides example sidelink control information sending methods and example communications devices. One example method includes sending, by a first communications device, first sub control information to a second communications device and a third communications device, where the first sub control information is scrambled by using a common scrambling sequence, the first communications device and the second communications device belong to a first communications device group, and the third communications device does not belong to the first communications device group. The first communications device can then send second sub control information to the second communications device, where the second sub control information is scrambled by using a scrambling sequence generated by using a user equipment identifier of the second communications device or a scrambling sequence generated by using a group identifier of the first communications device group.
