Handling of beam pair links

Abstract:

There is provided mechanisms for causing a switch to an alternative beam pair link. A terminal device is configured with a trigger condition for beam link failure. A method is performed by the terminal device. The method comprises estimating, during communication with a network node over a current beam pair link, that performance of the communication would be better if using the alternative beam pair link instead of the current beam pair link for the communication. The method comprises reporting beam link failure of the current beam pair link to the network node, without the trigger condition for beam link failure of the current beam pair link being met, thereby causing the switch to the alternative beam pair link.
