Title
(EN) SEARCH SPACE SET ACTIVATION
(FR) ACTIVATION D'UN ENSEMBLE D'ESPACES DE RECHERCHE
Abstract
(EN) Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may monitor a physical downlink control channel (PDCCH) monitoring occasion defined by an active search space (SS) set. The UE may receive, during the PDCCH monitoring occasion, a downlink control information (DCI). In response, the UE may activate at least one deactivated SS set based on the DCI and a mapping that associates an SS set to a DCI type, DCI format, transmission direction, or specific combinations thereof. In another aspect, a UE may monitor a subset less than all of PDCCH monitoring occasions defined by an active SS set. The UE may receive, during a PDCCH monitoring occasion, a DCI. In response, the UE may monitor a larger number of PDCCH monitoring occasions defined by the active SS set.
(FR) Sont divulguées diverses techniques de communication sans fil. Selon un aspect, un équipement utilisateur (UE) peut exécuter les étapes consistant à : surveiller une occasion de surveillance d'un canal physique de commande de liaison descendante (PDCCH) définie par un ensemble d'espaces de recherche (SS) actif ; pendant l'occasion de surveillance de PDCCH, recevoir des informations de commande de liaison descendante (DCI) ; et en réponse, activer au moins un ensemble de SS désactivé sur la base des DCI et d'une mise en correspondance qui associe un ensemble de SS à un type de DCI, à un format de DCI, à une direction de transmission ou à des combinaisons spécifiques de ces éléments. Selon un autre aspect, un UE peut exécuter les étapes consistant à : surveiller un sous-ensemble plus petit que l'ensemble des occasions de surveillance de PDCCH définies par un ensemble de SS actif ; pendant une occasion de surveillance de PDCCH, recevoir des DCI ; et en réponse, surveiller un grand nombre d'occasions de surveillance de PDCCH définies par l'ensemble de SS actif.
