Title
(EN) BEAM FAILURE RECOVERY MECHANISM FOR SECONDARY CELL
(FR) MÉCANISME DE REPRISE SUR DÉFAILLANCE DE FAISCEAU DESTINÉ À UNE CELLULE SECONDAIRE
Abstract
(EN)
Aspects of the present disclosure relate to wireless communications, and more particularly, to cell recovery techniques. One example method generally includes receiving, at a user-equipment (UE), at least one pilot signal via a secondary cell, receive, via a primary cell, a first message triggering reporting of at least one preferred beam for communication via the secondary cell, determining the preferred beam based on the at least one pilot signal, transmitting, via the primary cell, a report indicating the at least one preferred beam, and communicating data via the secondary cell and via the preferred beam.
(FR)
Des aspects de la présente invention concernent des communications sans fil et, plus particulièrement, des techniques de reprise de cellule. Un procédé donné à titre d'exemple consiste généralement à recevoir, au niveau d'un équipement utilisateur (UE), au moins un signal pilote par l'intermédiaire d'une cellule secondaire, à recevoir, par l'intermédiaire d'une cellule primaire, un premier message déclenchant un rapport d'au moins un faisceau préféré pour une communication par l'intermédiaire de la cellule secondaire, à déterminer le faisceau préféré sur la base du ou des signaux pilotes, à transmettre, par l'intermédiaire de la cellule primaire, un rapport indiquant le ou les faisceaux préférés et à communiquer des données par l'intermédiaire de la cellule secondaire et par l'intermédiaire du faisceau préféré.
