Abstract

Techniques and examples of support for beam failure recovery on secondary cell in mobile communications are described. An apparatus (e.g., user equipment (UE) ) detects a beam failure in wireless communication with a secondary cell (SCell) of a wireless network. The apparatus then signals on a network-configured resource an indication to inform the wireless network of the beam failure on the SCell. In response to the signaling, the apparatus receives a response from the wireless network.
