Title
(EN) VARIABLE SIZE PHYSICAL SIDELINK CONTROL CHANNEL AND AGGREGATION
(FR) CANAL DE COMMANDE DE LIAISON LATÉRALE PHYSIQUE DE TAILLE VARIABLE ET AGRÉGATION
Abstract
(EN)
Using a modulation and coding scheme for a control channel that is more conservative than needed to fulfill the control function may waste resources. To address this issue, a variable size control channel is provided. An apparatus in such a system may be configured to determine an aggregation level of a plurality of aggregation levels associated with a control channel. Each aggregation level of the plurality of aggregation levels is associated with a number of time-frequency resources dedicated for the control channel and a particular modulation and coding scheme used for modulating and coding control information in the control channel. The apparatus is configured to receive control information in the time-frequency resources associated with the aggregation level and decode the control information received in the time-frequency resources associated with the determined aggregation level. The decoding is based on the particular modulation and coding scheme associated with the determined aggregation level.

L’utilisation d'un schéma de modulation et de codage pour un canal de commande qui est plus conservateur que nécessaire pour satisfaire la fonction de commande peut gaspiller des ressources. La solution selon l'invention porte sur un canal de commande de taille variable. Un appareil dans un tel système peut être configuré pour déterminer un niveau d'agrégation d'une pluralité de niveaux d'agrégation associés à un canal de commande. Chaque niveau d'agrégation de la pluralité de niveaux d'agrégation est associé à un certain nombre de ressources temps-fréquence dédiées au canal de commande et à un schéma de modulation et de codage particulier utilisé pour moduler et coder des informations de commande dans le canal de commande. L'appareil est configuré pour recevoir des informations de commande dans les ressources temps-fréquence associées au niveau d'agrégation et décoder les informations de commande reçues dans les ressources temps-fréquence associées au niveau d'agrégation déterminé. Le décodage est basé sur le schéma de modulation et de codage particulier associé au niveau d'agrégation déterminé.
