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 uplink slot in which an acknowledgement (ACK) message for the beam configuration information is transmitted 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.

Abstract: Embodiments of this application disclose channel state information feedback and receiving methods, a transmit-end device and a receive-end device, and relate to the field of communications technologies. The method includes: generating and sending, by a transmit-end device, codebook indication information of K transport layers, where K is an integer greater than or equal to 2; the codebook indication information includes: L pieces of beam information used by the K transport layers, and indication information used to indicate beam information associated with each of the K transport layers; L is an integer greater than or equal to 2, and a quantity of pieces of beam information associated with at least one of the K transport layers is less than L. Implementing a channel state information feedback and receiving technology provided in this application helps reduce feedback overheads of channel state information.

Abstract: The present disclosure relates to beam configuration methods and apparatus. One example method include 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 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.
