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 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: This application disclose a method for indicating and determining a precoding vector related to precoding technologies to increase an overall system performance gain. The method may include: generating indication information, and sending the indication information. The indication information is used to indicate a plurality of component vectors of a precoding vector and a combination coefficient of each component vector. The combination coefficient of the component vector includes at least one of the following types: a wideband amplitude coefficient, a narrowband amplitude coefficient, and a narrowband phase coefficient.

Abstract: The present disclosure relates to beam configuration methods and apparatus. One example method include receiving beam configuration information from a network device, where the beam configuration information indicates a terminal device to transmit or receive a signal by using a first beam, and transmitting or receiving the signal by using at least the first beam after a first preset duration starting from a first time-domain unit, where the first time-domain unit is an unlink slot in which an acknowledgement (ACK) message for the beam configuration information is transmitted to the network device.

Abstract: The present disclosure relates to beam configuration methods and apparatus. One example method includes receiving, by a terminal device, a first beam from a network device, where an identifier of a reference signal sent on the first beam is a first identifier, and configuring, by the terminal device based on a spatial reception parameter, a receive beam corresponding to the first beam. The spatial reception parameter is configured after a second beam corresponding to the first identifier is measured or reported last time.

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.
