USER EQUIPMENT, RADIO NETWORK NODE AND METHODS PERFORMED THEREIN FOR HANDLING COMMUNICATION IN A WIRELESS COMMUNICATION NETWORK
Last updated:
Abstract:
Embodiments herein disclose, e.g., a method performed by a user equipment, UE, for handling communication in a wireless communication network, wherein the UE is in a connected mode in a first beam connected to a radio network node. The UE detects a beam failure of the first beam and transmits, to the radio network node, a preamble of a random access procedure in a second beam, wherein the preamble or a random access resource used for the preamble is associated with a beam failure recovery. The UE then receives a random access response, RAR, from the radio network node, wherein the RAR includes an uplink, UL, grant but without a temporary identity that is used by a medium access control, MAC, entity during a random access procedure.
