An apparatus for a user equipment operating in a multi-beam based communication session, the apparatus comprising means for performing: monitoring signal qualities for a plurality of beams in the multi-beam based communication session; determining a beam link failure, BLF, occurring for at least one of the beams in the multi-beam based communication session; characterized in that the means are further configured for performing: determining a type of the beam in which the BLF is occurring; and updating a radio link failure, RLF, related condition in dependence on the type of the beam in which the BLF is occurring, wherein updating the RLF related condition comprises: when the type of beam is a downlink beam carrying physical downlink control channel: updating the RLF related condition only in response to detecting that a BLF occurs for all of the downlink beams carrying physical downlink control channel; or when the type of beam is an uplink beam or a downlink/uplink beam: updating the RLF related condition in response to detecting that a BLF occurs for even one uplink beam or downlink/uplink beam. monitoring signal qualities for a plurality of beams in the multi-beam based communication session; determining a beam link failure, BLF, occurring for at least one of the beams in the multi-beam based communication session; characterized in that the means are further configured for performing: determining a type of the beam in which the BLF is occurring; and updating a radio link failure, RLF, related condition in dependence on the type of the beam in which the BLF is occurring, wherein updating the RLF related condition comprises: when the type of beam is a downlink beam carrying physical downlink control channel: updating the RLF related condition only in response to detecting that a BLF occurs for all of the downlink beams carrying physical downlink control channel; or when the type of beam is an uplink beam or a downlink/uplink beam: updating the RLF related condition in response to detecting that a BLF occurs for even one uplink beam or downlink/uplink beam. determining a type of the beam in which the BLF is occurring; and updating a radio link failure, RLF, related condition in dependence on the type of the beam in which the BLF is occurring, wherein updating the RLF related condition comprises: when the type of beam is a downlink beam carrying physical downlink control channel: updating the RLF related condition only in response to detecting that a BLF occurs for all of the downlink beams carrying physical downlink control channel; or when the type of beam is an uplink beam or a downlink/uplink beam: updating the RLF related condition in response to detecting that a BLF occurs for even one uplink beam or downlink/uplink beam. when the type of beam is a downlink beam carrying physical downlink control channel: updating the RLF related condition only in response to detecting that a BLF occurs for all of the downlink beams carrying physical downlink control channel; or when the type of beam is an uplink beam or a downlink/uplink beam: updating the RLF related condition in response to detecting that a BLF occurs for even one uplink beam or downlink/uplink beam.
