Title
(EN) SYSTEM AND METHOD FOR UE PROCESSING TIME RELAXATION FOR MULTI-TRP TRANSMISSION
(FR) SYSTÈME ET PROCÉDÉ DE RELAXATION TEMPORELLE DE TRAITEMENT D'UE POUR TRANSMISSION MULTI-TRP
Abstract
(EN)
Systems, devices, and techniques for adjusting a user equipment (UE) processing time parameter in a wireless communication system that include transmission and reception points (TRPs) are described. A described technique performed by UE includes receiving a first physical downlink shared channel (PDSCH) from a first TRP corresponding to a first scheduling physical downlink control channel (PDCCH) and a second PDSCH from a second TRP corresponding to a second scheduling PDCCH. The technique further includes transmitting a first hybrid automatic repeat request acknowledgement (HARQ-ACK) message and a second HARQ-ACK message based on the first PDSCH and the second PDSCH in accordance with a first processing time parameter and a second processing time parameter, respectively. The first processing time parameter can be based on a PDSCH mapping type, a processing capability of the UE, and one or more timing characteristics of the first PDSCH and the second PDSCH.

L'invention concerne des systèmes, des dispositifs et des techniques pour ajuster un paramètre de temps de traitement d'équipement utilisateur (UE) dans un système de communication sans fil qui comprennent des points d'émission et de réception (TRP). Une technique selon l'invention, effectuée par un UE, consiste à recevoir un premier canal partagé en liaison descendante physique (PDSCH) à partir d'un premier TRP correspondant à un premier canal de commande en liaison descendante physique (PDCCH) de planification et un second PDSCH à partir d'un second TRP correspondant à un second PDCCH de planification. La technique consiste en outre à transmettre un premier message d'accusé de réception de demande de répétition automatique hybride (HARQ-ACK) et un second message HARQ-ACK sur la base du premier PDSCH et du second PDSCH conformément, respectivement, à un premier paramètre de temps de traitement et à un second paramètre de temps de traitement. Le premier paramètre de temps de traitement peut être basé sur un type de mappage PDSCH, une capacité de traitement de l'UE et une ou plusieurs caractéristiques de synchronisation du premier PDSCH et du second PDSCH.
