Abstract: Embodiments of this application disclose a wireless communication method and an apparatus. The method includes: determining a target MCS if a current MCS exceeds a predetermined threshold, where the target MCS is an MCS less than or equal to the predetermined threshold; mapping a PTRS to one or more symbols based on the target MCS; and sending, to a terminal device, the symbol to which the PTRS is mapped. through implementation of the embodiments of this application, when the current MCS exceeds the predetermined threshold, the target MCS that is less than or equal to the predetermined threshold may be determined, so that a density of a PTRS on a time-frequency resource can be flexibly determined based on the target MCS and an association relationship between an MCS threshold and a time domain density of a PTRS, thereby helping reduce resource overheads of the PTRS.

Abstract: A cell handover method and an apparatus. Indication information is received from a source cell, where the indication information indicates to a first transmission configuration indicator TCI state and cell handover; initiating random access to a target cell according to the indication information. In response to first response information returned by the target cell being received, second response information is returned to the source cell, where the second response information indicates that the first TCI state is successfully activated. Cell handover is implemented through beam switch to reduce a delay of a terminal device during the cell handover. The terminal device returns the second response information to the source cell only after receiving the first response information returned by the target cell.
