Abstract

Certains modes de réalisation comprennent un système, un appareil, un article de fabrication, un procédé et/ou un produit programme informatique et/ou des combinaisons et des sous-combinaisons de ceux-ci, pour des opérations d'économie d'énergie implicites pour un répéteur commandé par réseau (NCR) dans un réseau sans fil. Certains modes de réalisation comprennent un NCR qui peut recevoir un format d'informations de commande de liaison descendante (DCI) comprenant une première périodicité de surveillance de canal physique de contrôle descendant (PDCCH), KS1, et fonctionner dans un état activé pendant une durée de KS1. Le NCR peut détecter une périodicité de surveillance de PDCCH sautée, et fonctionner dans un état éteint pendant une durée correspondant à la périodicité de surveillance de PDCCH sautée. Dans certains modes de réalisation, le NCR fonctionne avec un composant de porteuse (CC) avec un spectre non apparié prenant en charge des duplex par séparation temporelle (TDD) de configurations de créneau de liaison montante (UL)-liaison descendante (DL)-"ConfigurationCommon" ou "tdd-UL-DLConfigurationDedicated". Le NCR peut détecter à partir d'un bloc d'informations système (SIB), un symbole de multiplexage par répartition orthogonale de la fréquence (OFDM) flexible, et fonctionner dans un état éteint pendant une durée du symbole OFDM flexible.
