Regarding claim 26, Alfarhan discloses the UE according to claim 22, wherein the plurality of first RS resources belong to a first cell identified by the first PCI, and the plurality of second RS resources belong to a second cell identified by the second PCI, the first cell is a serving cell of the UE that is a Primary Cell (PCell), a Primary Secondary Cell (PSCell) or a Secondary Cell (SCell) { (see pg. 8, [0081, 0083, 0092]; pg. 13, [0176]; pg. 12, [0164]; Figs. 1A-6) }. Regarding claim 27, Alfarhan discloses the UE according to claim 22, wherein any first RS resource of the plurality of first RS resources is different from any second RS resource of the plurality of second RS resources { (see pg. 8, [0081, 0083, 0092]; pg. 13, [0176]; pg. 12, [0164]; Figs. 1A-6) }. Regarding claim 28, Alfarhan discloses the UE according to claim 21, wherein: on a condition that the radio link quality is worse than a first threshold, a physical layer of the UE is configured to report a beam failure instance indication to a higher layer of the UE { (see pg. 13, [0176]; pg. 12, [0164]; pg. 8, [0092]; Figs. 1A-6) }. Regarding claim 29, Alfarhan discloses the UE according to claim 21, wherein: a higher layer of the UE is configured to receive a beam failure instance indication from a physical layer of the UE, and the UE is configured to increment the beam failure instance indication counter by in response to the beam failure instance indication { (see pg. 2, [0014]; Figs. 1A-6) }.
