Abstract

A method for transmit timing adjustment by a second network node includes obtaining an indication of beam link failure of a current beam that is used for ongoing communication with a first network node. The method further includes switching over to a backup beam of the current beam for continuing the ongoing communication with the first network node, and adjusting transmit timing for transmitting a signal as part of the ongoing communication in the backup beam based on earlier communicated timing information with the first network node before making any transmission of the signal on the backup beam.
