1. A user equipment 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 being configured, with the at least one processor, to cause the user equipment to perform:
receive from a network node at least one cell individual offset associated with at least one respective candidate beam in a serving cell;
switch in the serving cell to a new beam among the at least one candidate beam;
select a cell individual offset associated with the new beam; and
when served by multiple source beams from different transmission and reception points, apply a cell individual offset of a beam providing a physical downlink control channel, when the physical downlink control channel is provided on a single beam,
wherein the new beam is a beam autonomously decided for use when performing beam failure recovery in the serving cell,
wherein the at least one cell individual offset is further associated with candidate neighbor beams in a neighbor cell, and wherein the selected cell individual offset further corresponds to a candidate neighbor beam in the neighbor cell,
wherein a beam identifier corresponds to:
an index of a Channel State Information Reference Signal (CSI-RS), the CSI-RS being quasi co-located with a De-Modulation Reference Signal (DMRS) of a physical downlink control channel and a physical downlink shared channel used by the user equipment for communication,
wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the user equipment to:
continue an evaluation of a handover condition with a new cell individual offset without resetting a time-to-trigger timer, in case the time-to-trigger timer of a measurement reporting event is running.
