Abstract
(EN)
Wireless communications systems and methods related to downlink control channel communications in a wireless communication network are provided. A first wireless communication device communicates, with a second wireless communication device, a configuration indicating a first group of one or more search spaces and a second group of one or more search spaces, where at least one of the first group or the second group includes at least one search space not included in an other of the first group or the second group. The first wireless communication device communicates, with the second wireless communication device, a first downlink control information (DCI) message in a first search space of the first group of one or more search spaces. The first wireless communication device communicates, with the second wireless communication device, a second DCI message in a second search space of the second group of one or more search spaces.

L'invention concerne des systèmes et des procédés de communications sans fil relatifs à des communications par un canal de commande de liaison descendante dans un réseau de communication sans fil. Un premier dispositif de communication sans fil communique à un second dispositif de communication sans fil une configuration indiquant un premier groupe d'un ou plusieurs espaces de recherche et un second groupe d'un ou plusieurs espaces de recherche, au moins l'un du premier groupe et du second groupe comprenant au moins un espace de recherche non inclus dans un autre du premier groupe et du second groupe. Le premier dispositif de communication sans fil communique au second dispositif de communication sans fil un premier message d'informations de commande de liaison descendante (DCI) dans un premier espace de recherche du premier groupe d'un ou plusieurs espaces de recherche. Le premier dispositif de communication sans fil communique au second dispositif de communication sans fil un second message de DCI dans un second espace de recherche du second groupe d'un ou plusieurs espaces de recherche.
