US 2023/0413077 A1 · BEAM FAILURE DETECTION

Abstract

A method (200) performed by a UE (102). The method includes receiving (s202) one or more messages for activating at least i) a first set of configured TCI states and ii) a second set of configured TCI states, wherein the first set of activated TCI states is associated with a first PCI and indicates a first set of reference signals, and the second set of activated TCI states is associated with a second PCI and indicates a second set of reference signals. The method also includes performing (s204) beam failure detection, BFD, monitoring. Performing the BFD monitoring comprises: determining (s206) whether a beam failure with respect to the first PCI has occurred based on the first set of reference signals; and determining (s208) whether a beam failure with respect to the second PCI has occurred based on the second set of reference signals.

A method performed by a user equipment (UE), the method comprising:

receiving one or more messages for activating at least i) a first set of configured TCI states and ii) a second set of configured TCI states, wherein the first set of activated TCI states is associated with a first physical cell identifier (PCI) and indicates a first set of reference signals, and the second set of activated TCI states is associated with a second PCI and indicates a second set of reference signals;
and
performing beam failure detection (BFD) monitoring, wherein performing the BFD monitoring comprises at least one of:
determining whether a beam failure with respect to the first PCI has occurred based on the first set of reference signals;
or
determining whether a beam failure with respect to the second PCI has occurred based on the second set of reference signals.

A user equipment (UE), comprising:

a receiver for receiving one or more messages for activating at least i) a first set of configured TCI states and ii) a second set of configured TCI states, wherein the first set of activated TCI states is associated with a first physical cell identifier (POI configured for the UE and indicates a first set of reference signals, and the second set of activated TCI states is associated with a second PCI configured for the UE and indicates a second set of reference signals;
processing circuitry;
and
a memory containing instructions executable by the processing circuitry, wherein the UE is configured to perform beam failure detection (BFD) monitoring, wherein performing the BFD monitoring comprises:
determining whether a beam failure with respect to the first PCI has occurred based on the first set of reference signals;
and
determining whether a beam failure with respect to the second PCI has occurred based on the second set of reference signals.
