Abstract[English]
Various aspects of the present disclosure relate to on-demand system information request. An apparatus, such as a UE, receives, from a serving cell, a configuration that indicates first configuration information for requesting system information block 1 (SIB1) and second configuration information that indicates one or more physical random access channel (PRACH) resources for requesting SIB1 of at least one network energy saving (NES) cell. The UE receives, from the serving cell, information that indicates a synchronization signal block (SSB) subcarrier offset and a physical downlink control channel (PDCCH) configuration for SIB1 acquisition from the at least one NES cell. The UE transmits, to the at least one NES cell, a SIB1 request based at least in part on the first configuration information and a failed SIB1 acquisition.[French]
Divers aspects de la présente divulgation concernent une demande d'informations de système à la demande. Un appareil, tel qu'un UE, reçoit, en provenance d'une cellule de desserte, une configuration qui indique des premières informations de configuration pour demander un bloc d'informations système 1 (SIB1) et des secondes informations de configuration qui indiquent une ou plusieurs ressources de canal d'accès aléatoire physique (PRACH) pour demander un SIB1 d'au moins une cellule d'économie d'énergie de réseau (NES). L'UE reçoit, en provenance de la cellule de desserte, des informations qui indiquent un décalage de sous-porteuse de bloc de signal de synchronisation (SSB) et une configuration de canal de commande de liaison descendante physique (PDCCH) pour une acquisition SIB1 à partir de la ou des cellules NES. L'UE transmet, à la ou aux cellules NES, une demande SIB1 sur la base, au moins en partie, des premières informations de configuration et d'une acquisition SIB1 défaillante.
