Abstract: This application describes a data transmission method, a terminal device, and a network device. The method may include determining, by a terminal device, a reporting type of channel state information (CSI), where the reporting type is used to indicate a relationship between CSI of a beam that is currently reported by the terminal device and CSI of a beam that is previously reported by the terminal device in a current reporting period. The method may also include sending, by the terminal device, CSI of N beams to a network device based on a reporting type and a codebook parameter, where the codebook parameter is used to indicate a quantity N of the currently reported beams, and N is an integer greater than or equal to 1. According to the data transmission method, the terminal device, and the network device described in the embodiments of this application, CSI reporting flexibility can be improved, thereby improving system performance.

Abstract: A method includes generating, by a processor, first indication information based on N reference signals, where N is an integer and N≥2. The first indication information indicates a plurality of component vectors for constructing a precoding matrix and a superposition coefficient of each component vector of each of M precoding vectors for constructing the precoding matrix upon which a precoding of M reference signals is based, where M is an integer and 1≤M

Abstract: The present disclosure relates to beam configuration methods. In one example method, a terminal device receives a first beam from a network device, where an identifier of a reference signal sent on the first beam is a first identifier. The terminal device configures a receive beam corresponding to the first beam based on a spatial reception parameter corresponding to a downlink synchronization signal associated with current measurement, where before receiving the first beam, the terminal device does not measure or report a second beam corresponding to the first identifier.

Abstract: The present disclosure relates to beam configuration methods and apparatus. One example method includes receiving, by a terminal, beam configuration information from a network device, where the beam configuration information is used to instruct the terminal to transmit a signal by using a first beam, and transmitting, by the terminal, the signal by using at least the first beam when a first preset duration starting from a first time point expires, where the first time point is a time point at which the terminal sends an acknowledgement (ACK) message for the beam configuration information to the network device.

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.
