Abstract: This application provides a beam failure recovery method, an apparatus, and a system. In this solution, a terminal device receives first configuration information from a network device, and performs cell-level beam failure recovery or transmission reception point level (TRP-level) beam failure recovery based on the first configuration information. The first configuration information is used to configure a plurality of sets of beam failure detection resources and a plurality of sets of candidate beam resources. Based on this solution, the terminal device may perform partial beam failure recovery based on the plurality of sets of beam failure detection resources and the plurality of sets of candidate beam resources, so that the terminal device can detect a TRP-level beam failure and recover the TRP-level beam failure in time. This effectively improves smooth system evolution.

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.
