Abstract: A signal transmission method and apparatus, a device, and a system are provided. The signal transmission method includes: sending first signaling to a receive end device, where the first signaling is used to indicate configuration information of a first signal; and the configuration information includes at least one of the following: first information, a signal waveform, a target measurement quantity, or signal sequence information, where the first information is used to indicate a signal type of the first signal, or indicate whether the receive end device detects communication information of the first signal; and the target measurement quantity includes a measurement quantity to be measured or fed back by the receive end device.

Abstract: A lipid delivery system, a virus-like structure (VLS) vaccine constructed therefrom, and a lipid particle capable of encapsulating an mRNA molecule encoding a SARS-CoV-2-specific antigen are provided. After the lipid particle encapsulates an mRNA molecule encoding a SARS-CoV-2 antigen, a SARS-CoV-2 S1 antigen protein can be embedded on a surface of an envelope structure of the lipid under specific buffer conditions to produce a VLS vaccine with an antigen-encoding mRNA molecule encapsulated inside and an outer membrane presenting a required viral antigen protein. The vaccine has a superior specific antibody-inducing ability to a SARS-CoV-2 mRNA vaccine and a polypeptide vaccine, can maintain a long-lasting high antibody level, and can also exhibit excellent immune binding abilities for the emerging different variants.

Abstract: A scheduling method and apparatus, a device, and a readable storage medium are provided. The scheduling method in an embodiment of this application includes: receiving, by a terminal, first scheduling information and/or second scheduling information; where the first scheduling information is used to schedule a terminal in a case that the terminal reports transmission scheme switching capability information, the transmission scheme switching referring to switching between an SFN transmission scheme and other transmission schemes; and the second scheduling information is used to schedule the terminal in a case that the network-side device configures an SFN transmission scheme.

Abstract: This application provides a transmission mode determining method and apparatus, and a communications device, and pertains to the field of communications. The method includes: determining a single frequency network transmission mode in a target indication manner, where the target indication manner includes one of the following manners: indication by RRC signaling, indication by TCI state, a manner with a configured or indicated target parameter satisfying a predetermined parameter requirement, and indication of a PDCCH using the SFN transmission mode.

Abstract: A reference signal sending method and a transmitter are provided. The method includes: determining a time-frequency resource pattern of a target reference signal used for interference measurement, where the time-frequency resource pattern is used to indicate a time domain location and a frequency domain location of the target reference signal; and sending the target reference signal based on the time-frequency resource pattern.
