Abstract: There is provided a method performed by a user equipment (UE). The method comprises: receiving a message for activating multiple Transmission Configuration Indicators (TCIs) configured for the UE; and performing Radio Link Monitoring (RLM) measurements, for a plurality of Transmission Reception Points (TRPs) configured for the UE, on reference signals associated with multiple Physical Cell Identifiers (PCIs), wherein the reference signals are configured as Quasi-Colocation (QCL) source of the activated TCI states. A UE for implementing this method is also provided.

Abstract: A user equipment (UE) may receive an area indication transmitted by a network node. The area indication may identify an area to which a public warning system (PWS) message is applicable. The area indication may not include coordinates and/or shapes that define a geographical area to which the PWS message is applicable. The area indication may include a country indication that identifies a country to which the PWS message is applicable and/or a network indication that identifies a network (or part of a network) to which the PWS message is applicable. The UE may determine whether the UE is in the area to which the PWS message is applicable. Based on the determination, the UE may display or discard the PWS message.

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.

Abstract: A method, network node and wireless device (WD) for dynamic non-coherent joint transmission channel state information (CSI) indication are disclosed. According to one aspect, a method in a network node includes transmitting a first indication of a set of channel measurement resources (CMRs) for CSI. The CSI includes at least one of: a first CSI for multiple transmission and reception point (multi-TRP) physical downlink shared channel (PDSCH) transmission, and at least one second CSI for PDSCH transmission from one TRP. The method includes transmitting a second indication of a first subset of the set of CMRs to use for determining the first CSI. The method includes configuring the WD to use a second subset of the set of CMRs for determining the at least one second CSI, and receiving a CSI report comprising at least one of the first CSI and the at least one second CSI.

Abstract: According to some embodiments, a method is performed by a wireless device for adapting to intermittent network coverage in a non-terrestrial network (NTN). The method comprises: receiving information indicative of the availability of NTN network access; and determining whether the wireless device is within or outside of an area with NTN network access based in part on the received information and a location of the wireless device. Upon determining that the wireless device is outside the area with NTN network access, the wireless device operates in a reduced power mode in which one or more internal processes are suspended or disabled. Upon determining that the wireless device is within the area with NTN network access, the wireless device operates in a normal power mode in which one or more of the internal processes that were suspended or disabled are reactivated or enabled.

Abstract: Disclosed herein is a method performed by a wireless device for optimized reconfiguration of radio link monitoring, RLM, and beam monitoring. The method includes receiving, from a first network node, a first message comprising at least one RLM parameter related to at least one reference signal. The method further includes receiving, from the first network node, a second message comprising a bitmap indicating activation of at least one RLM parameter associated with the first message. The method additionally includes monitoring one or more reference signals based on the first message and the second message.
