    Abstract: A method for indicating quasi co-location indication information and a device are provided, to diversify reference signal types and reference signal configuration information that are indicated by QCL. The method includes: generating, by a base station, reference signal configuration information; performing, by the base station based on the reference signal configuration information, quasi co-location QCL assumption on reference signals corresponding to at least two antenna ports in reference signals, to generate QCL indication information; and sending, by the base station, the QCL indication information to a terminal.

    Abstract: This application provides a phase tracking reference signal (PTRS) sending method and apparatus. The method includes: implicitly determining, by a terminal device based on obtained uplink grant information and a preset rule, a to-be-sent PTRS and an antenna port for carrying the to-be-sent PTRS, where the antenna port is selected from an antenna port set, and the to-be-sent PTRS is one or more of all available PTRSs; and putting the to-be-sent PTRS on the antenna port, and sending the to-be-sent PTRS on the antenna port. This implicit indication method can effectively reduce air interface signaling overheads and improve air interface efficiency.

    Abstract: Embodiments of this application provide a parameter determining method, a base station, and user equipment. The parameter determining method provided in this application includes: determining, by a base station, a first subcarrier spacing corresponding to UE; and notifying, by the base station, the UE of the first subcarrier spacing. In the embodiments of this application, the UE may accurately learn of, in a multi-subcarrier-spacing system, a subcarrier spacing used for data transmission, and then perform data transmission. This can effectively ensure that the UE performs a corresponding service, thereby meeting a corresponding service requirement.

    Abstract: A measurement and reporting method is provided. The method includes: receiving, by a terminal, a measurement configuration from a base station, the measurement configuration indicates a plurality of measurement objects to be measured; obtaining measurement results and channel characteristic values respectively corresponding to the plurality of measurement objects; and sending channel characteristic values and measurement results respectively corresponding to some or all of the plurality of measurement objects, or group identification information and measurement results respectively corresponding to some or all of the plurality of measurement objects, where different groups correspond to different channel characteristic values. The base station determines, from a plurality of measurement object groups, a plurality of target measurement objects used to send data to the terminal. Different groups correspond to different channel characteristic values. Therefore the plurality of target measurement objects from the plurality of measurement object groups are not easily shielded at the same time.

    Abstract: The present disclosure provides example communication methods and example communication apparatuses for non-coherent transmission. One example communication method includes determining P1 first symbols based on a first to-be-modulated bit, where P1=M×N1, N1 is a quantity of resource units used to carry the P1 first symbols, M is a positive integer, and N1 is an integer greater than 1. P2 second symbols are determined based on a second to-be-modulated bit, where P2=M×N2, and N2 is an integer greater than 1. P3 third symbols are determined based on the P1 first symbols and the P2 second symbols, where P3=M×N3, N3 is a quantity of resource units used to carry the P3 third symbols, and N3 is less than or equal to N2. The P1 first symbols and the P3 third symbols are sent.
