Method and system for beam tracking failure recovery

A non-transitory computer-readable storage medium, having stored thereon a computer program comprising instructions which, when executed on at least one processor, cause the at least one processor to:

• perform a beam tracking of the serving cell for tracking one or more beams of the serving cell based on measured signal strength or measured signal quality, wherein the beam tracking comprises collecting in the wireless device a snapshot and/or sample of a synchronization signal, SS, Block Burst or Burst Set;
• detect a beam failure process in the serving cell;
• in response to detection of the beam failure process, trigger a beam recovery process associated with a downlink, DL, beam for the serving cell, wherein the DL beam is selected based on the beam tracking performed prior to detecting the beam failure process;
• and
• when a confirmation for the selected DL beam from the radio network node is lacking during a time window, transmit a request to access another beam being a second best beam according to the performed beam tracking.

A wireless device for handling communication of the wireless device in a wireless communication network, wherein the wireless communication network comprises a radio network node configured to serve the wireless device in a serving cell, and wherein the wireless device comprises processing circuitry and a memory, said memory comprising instructions executable by said processing circuitry whereby said wireless device is operative to:

• perform a beam tracking of the serving cell for tracking one or more beams of the serving cell based on measured signal strength or measured signal quality, wherein the beam tracking comprises collecting in the wireless device a snapshot and/or sample of a synchronization signal, SS, Block Burst or Burst Set;
• detect a beam failure process in the serving cell;
• in response to detection of the beam failure process, trigger a beam recovery process associated with a downlink, DL, beam for the serving cell, wherein the DL beam is selected based on the beam tracking performed prior to detecting the beam failure process;
• and
• when a confirmation for the selected DL beam from the radio network node is lacking during a time window, transmit a request to access another beam being a second best beam according to the performed beam tracking.
