User equipment and method thereof
View Patent ↗The present invention provides a link evaluation method in user equipment and user equipment. The user equipment has a discontinuous reception (DRX) mode and a non-DRX mode. The link evaluation method comprises: measuring a reference signal in an evaluation period; and in the case that a measurement result is lower than a preset threshold, judging that a beam failure instance (BFI) is generated, and notifying a higher layer of the BFI at an interval of an indication period, wherein when the user equipment is in the non-DRX mode, the duration of the evaluation period is first duration; when the user equipment is in the DRX mode, the duration of the evaluation period is second duration; and the second duration is greater than the first duration.
1. A user equipment, comprising:
an evaluating unit configured to evaluate a link quality; and
a notifying unit configured to notify a Beam Failure Instance (BFI) indication to a higher layer when the link quality is worse than a threshold, wherein
when a Discontinuous Reception (DRX) is not used, the BFI indication is notified at an interval equaling to a duration of a first indication periodicity,
when the DRX is used, the BFI indication is notified at an interval equaling to a duration of a second indication periodicity, and
the duration of the second indication periodicity is always greater than the duration of the first indication periodicity.
2. The user equipment according to claim 1 , wherein
a reference signal used to evaluate the link quality is Synchronization Signal Block (SSB) or Channel State Information Reference signal (CSI-RS).
3. The user equipment according to claim 2 , wherein
a value of the first indication periodicity is determined by a value of a periodicity of the reference signal;
a value of the second indication periodicity is a maximum value between (i) a first value obtained by multiplying DRX cycle length by a first factor and (ii) a second value obtained by multiplying the value of the periodicity of the reference signal by a second factor.
4. A method performed by a user equipment, comprising:
evaluating a link quality; and
notifying a Beam Failure Instance (BFI) indication to a higher layer when the link quality is worse than a threshold, wherein
when a Discontinuous Reception (DRX) is not used, the BFI indication is notified at an interval equaling to a duration of a first indication periodicity,
when the DRX is used, the BFI indication is notified at an interval equaling to a duration of a second indication periodicity, and
the duration of the second indication periodicity is always greater than the duration of the first indication periodicity.
5. The method according to claim 4 , wherein
a reference signal used to evaluate the link quality is Synchronization Signal Block (SSB) or Channel State Information Reference signal (CSI-RS).
6. The method according to claim 5 , wherein
a value of the first indication periodicity is determined by a value of a periodicity of the reference signal;
a value of the second indication periodicity is a maximum value between (i) a first value obtained by multiplying DRX cycle length by a first factor and (ii) a second value obtained by multiplying the value of the periodicity of the reference signal by a second factor.
