Examples pertaining to protocol improvement for redirection to another system in mobile communications are described. An apparatus in a 5.sup.th Generation System (5GS) receives, from a mobile network, a reject cause indicating that redirection to an Evolved Packet System (EPS) is required. Responsive to receiving the reject cause while no suitable cell of the first mobile network connected to an Evolved Packet Core (EPC) is found or while no cell of the first mobile network connected to an EPC can be selected, the apparatus enters a predefined 5.sup.th Generation Mobility Management (5GMM) state and starts a timer.

A system in wireless network including an Access Point utilizing at least an unlicensed first wireless interface; a Station utilizing at least a first unlicensed wireless interface, transmitting in uplink to the AP; Said at least one STA further includes a secondary wireless interface different from the first unlicensed wireless interface, said STA is configured to, determine that transmission of a message be in a secondary wireless interface of the STA when it is utilized for Reliable and Low Latency Communication RLLC data transmission, generate a message and then transmit the message to a serving AP. Said AP is configured to, when receiving the message from the STA, determine whether information will be generated based on the message received from the STA, generate at least scheduling information and transmit the generated information to the STA.

A wireless device may increment a beam failure instance counter based on detecting a first beam failure instance associated with one or more first reference signals, RSs, for beam failure detection. The wireless device may receive a medium access control control element, MAC CE, activating one or more second RSs for beam failure detection. The wireless device may resetting the beam failure instance counter in response to receiving the MAC CE. increment the beam failure instance counter based on detecting a second beam failure instance associated with the one or more second RSs. The wireless device may initiate a beam failure recovery based on the beam failure instance counter being equal to or greater than a first value.
