Abstract: A method, device, and storage medium are disclosed that determine beam information of an antenna port for a frequency domain resource not used for transmitting uplink data and/or uplink control information. In one embodiment, a first device determines, based on first configuration information, that a beam for sending a first uplink reference signal on a first antenna port is also a beam for sending a second uplink reference signal on a second antenna port, and sends the first uplink reference signal on the first antenna port. Beam information of the first antenna port can be determined based on beam information of the second antenna port, and the first uplink reference signal can be sent based on the determined beam information of the first antenna port. This can spare beam configuration performed by a network side for the first frequency domain resource, and reduce overheads for transmitting configuration information.

Abstract: An interference measurement reporting method, device, and system related to the field of communications technologies are disclosed. The method includes after receiving first information sent by a second device, sending, by a first device, at least one reported value to a third device. The first information is used to indicate an interference measurement resource to the first device. And the reported value is obtained based on an interference measurement result that is located on a portion the resource. Because the reported value is obtained based on the interference measurement performed on a specific resource of which the first device is notified previously, when the technical solution is applied to cross interference measurement, for example, inter-UE interference measurement, the first device can report accurate information about inter-UE interference status to a base station.

Abstract: This application discloses a resource indication method, a network device, and a terminal device, to improve utilization of a resource mapped to a DMRS port. The method includes: sending, by a network device, configuration information to a terminal device, so that the terminal device determines, based on the configuration information, that a second resource in first resources is used to transmit first information or that a third resource in first resources is not used to transmit first information, where the first resources are resources mapped to a DMRS port. In this way, the terminal device can multiplex the resources mapped to the DMRS port. When some of the first resources are not used to transmit a DMRS, the resources may be indicated to determine whether the resources may be used to transmit the first information, for example, the first information may be data, control information, or other information different from DMRS information, thereby ensuring maximum use of the resources mapped to the DMRS port, and improving resource utilization.

Abstract: This application discloses a reference signal configuration method and apparatus. Before a network device sends reference signals aperiodically, the network device sends configuration information to a terminal device, where the configuration information is used to indicate a timeslot offset of one or more reference signal resource sets. Therefore, the network device can flexibly send reference signals in different timeslots, thereby reducing a quantity of times of reference signal triggering and measurement result reporting, and improving efficiency of a communications system.

Abstract: Embodiments of this application provide a non-coherent data transmission method and a communication apparatus. In the method, a transmit end device determines, in a first constellation, a first constellation point corresponding to first to-be-modulated bits, where the first constellation point corresponds to P first symbols, P=M*N, M is a positive integer, and N is an integer greater than 1; and sends the P first symbols on N resource units by using M antenna ports, or sends P second symbols determined based on the P first symbols, and foregoes sending demodulation reference signals of the P first symbols or the P second symbols. In the method, a constellation is designed, and each constellation point in the constellation corresponds to a plurality of resource units so that data can be transmitted with no need to transmit a reference signal, and only the data needs to be transmitted.
