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: The present disclosure relates to channel state measurement methods and apparatus. One example method includes selecting, by a network device from N channel state information reference signal (CSI-RS) resources, a target CSI-RS resource and a target channel state information-interference measurement (CSI-IM) resource group associated with the target CSI-RS resource, where an ith CSI-RS resource in the N CSI-RS resources is associated with ni CSI-IM resource groups, and a kth CSI-IM resource group in the ni CSI-IM resource groups includes xik CSI-RS resources in the N CSI-RS resources except the ith CSI-RS resource, and sending, by the network device, first indication information by using first signaling, where the first indication information indicates the target CSI-RS resource and the target CSI-IM resource group.

Abstract: This application discloses a method for indicating PDSCH receiving information, a data receiving method, and an apparatus. According to this application, a network device generates first indication information, where the first indication information is used to indicate physical downlink shared channel PDSCH receiving information, and the PDSCH receiving information includes information identical to physical downlink control channel PDCCH receiving information; and the network device transmits the first indication information over a PDCCH. This application can be used to improve efficiency of indicating PDSCH receiving information, thereby improving PDSCH receiving performance.

Abstract: A reference signal transmission method is disclosed, the method including: determining at least two first reference signal resources; receiving a first channel based on the at least two first reference signal resources when a scheduling offset is less than or equal to a preset threshold and/or there is no spatial relation parameter information indication field in downlink control information DCI; and demodulating the first channel. When data on at least two reference signal resources needs to be received within a period of time, the method can increase a probability that a terminal device successfully receives the data.
