Abstract
(EN)
Provided are a monitoring method/device for monitoring a downlink control channel of a terminal in a wireless communication system, and a downlink control channel transmission method/device corresponding to the monitoring method/device. A PS-PDCCH including power saving information is monitored in a DRX-on period, and when the PS-PDCCH is detected, a PDCCH is monitored on the basis of same. The PS-PDCCH may provide notification about a specific search space set among a plurality of search space sets, and exceptionally skip PDCCH monitoring for the specific search space set.
(FR)
L'invention concerne un procédé/dispositif de surveillance pour surveiller un canal de commande de liaison descendante d'un terminal dans un système de communication sans fil, et un procédé/dispositif de transmission de canal de commande de liaison descendante correspondant au procédé/dispositif de surveillance. Un PS-PDCCH comprenant des informations d'économie d'énergie est surveillé lors d'une période pendant laquelle la DRX est en marche, et lorsque le PS-PDCCH est détecté, un PDCCH est surveillé sur la base de ce dernier. Le PS-PDCCH peut fournir une notification concernant un ensemble d'espace de recherche spécifique parmi une pluralité d'ensembles d'espace de recherche, et peut exceptionnellement sauter une surveillance de PDCCH pour l'ensemble d'espace de recherche spécifique.
