(EN) ENHANCED EVENT REPORTING FOR MULTIPLE-TRP CELL MOBILITY
(FR) RAPPORT D'ÉVÉNEMENT AMÉLIORÉ POUR MOBILITÉ CELLULAIRE À TRP MULTIPLES
Abstract
(EN) A method of operating a network node includes establishing a connection to a wireless device from a first transmission/reception point, TRP, that serves a multiple-TRP cell, and configuring the wireless device to generate measurement reports based on a TRP-specific reference signal transmitted by a second TRP that serves the multiple-TRP cell. A method of operating a wireless device includes establishing a connection to a first transmission/reception point, TRP, that serves a multiple-TRP cell, and generating a measurement report based on a TRP-specific reference signal transmitted by a second TRP that serves the multiple-TRP cell. Related devices and computer program products are disclosed.
