Abstract: This application discloses a data sending method, a data receiving method, and an apparatus. The data sending method includes: if first type data is punctured, preserving, by a network device, a punctured first data subset in the first type data and puncture location information of the first data subset in the first type data, and retransmitting the first data subset within a second scheduling period to a user equipment. In this way, the network device does not need to wait for feedback from the user equipment before the network device can perform a retransmission operation, so that latency of retransmission is reduced. In addition, the network device only needs to retransmit the punctured first data subset within the second scheduling period but does not need to retransmit the entire first type data, so that an amount of data to be retransmitted is reduced and fewer transmission resources are consumed.

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: This disclosure discloses a beam switching method and an apparatus. A terminal device receives first indication information from a network device, where the first indication information indicates a first beam. Then, the terminal device performs one or more of the following behaviors based on the first beam: measuring downlink time-frequency offset information and path loss information corresponding to the first beam, sending, based on the first beam, a signal for uplink timing measurement, and receiving uplink timing adjustment information from the network device, where the timing adjustment information is determined based on the first beam. Further, the terminal device receives second indication information from the network device, where the second indication information indicates to switch to the first beam. The terminal device first measures timing information and/or the path loss information of the first beam to be switched to.
