Abstract
A method including monitoring, by a user equipment (UE) operating in a multi-beam based communication session, signal qualities for a plurality of beams in the multi-beam based communication session (300); determining a beam link failure (BLF) occurring for at least one of the beams in the multi-beam based communication session (302); determining a type of the beam in which the beam link failure (BLF) is occurring (304); and updating a radio link failure (RLF) related condition in dependence on the type of the beam in which the beam link failure (BLF) is occurring (306).
Claims21
-23. (canceled)
An apparatus comprising:
- at least one processor;
- and
- at least one non-transitory memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause an apparatus operating in a multi-beam based communication session at least to:
- monitor signal qualities for a plurality of beams in the multi-beam based communication session;
- determine a beam link failure (BLF) occurring for at least one of the beams;
- detect whether or not BLF occurs for all of the beams of a predetermined type;
- and
- in response to detecting that BLF occurs for all of the beams of the predetermined type, decide to provide an indication of the BLF to a higher layer;
- and
- in response to detecting that there is at least one other beam of the predetermined type without BLF, decide not to provide an indication of the BLF to a higher layer.
A method, comprising:
- monitoring, at a user equipment (UE) operating in a multi-beam based communication session, 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;
- detecting whether or not BLF occurs for all of the beams of a predetermined type;
- and
- in response to detecting that BLF occurs for all of the beams of the predetermined type, deciding to provide an indication of the BLF to a higher layer;
- and
- in response to detecting that there is at least one other beam of the predetermined type without BLF, deciding not to provide an indication of the BLF to a higher layer.
A non-transitory computer-readable medium encoded with instructions that, when executed by a processor, cause an apparatus operating in a multi-beam based communication session at least to:
- monitor signal qualities for a plurality of beams in the multi-beam based communication session;
- determine a beam link failure (BLF) occurring for at least one of the beams;
- detect whether or not BLF occurs for all of the beams of a predetermined type;
- and
- in response to detecting that BLF occurs for all of the beams of the predetermined type, decide to provide an indication of the BLF to a higher layer;
- and
- in response to detecting that there is at least one other beam of the predetermined type without BLF, decide not to provide an indication of the BLF to a higher layer.
