Title
(EN) UPLINK CHANNEL TRANSMISSION FOR MULTIPLE TRANSMIT RECEIVE POINTS (TRPs)
(FR) TRANSMISSION DE CANAL DE LIAISON MONTANTE POUR MULTIPLES POINTS D'ÉMISSION-RÉCEPTION (TRP)
Abstract
(EN)
This disclosure provides systems, methods and apparatuses for uplink channel transmission for multiple transmit receive points (TRPs). In one aspect, a user equipment (UE) resolves overlapping physical uplink control channels (PUCCHs) in a slot or overlapping PUCCH(s) and PUSCH(s) that are mapped to a same TRP in a multi-TRP scenario and that are mapped to two or more different TRPs in the multi-TRP scenario. For example, in a multi-TRP scenario that includes two TRPs, the UE may eliminate overlap of these uplink channels for each of the two TRPs individually and may additionally eliminate overlap of these uplink channels between the two TRPs.
(FR)
La présente invention concerne des systèmes, des procédés et des appareils pour une transmission de canal de liaison montante pour de multiples points d'émission-réception (TRPs). Selon un aspect, un équipement utilisateur (UE) résout le problème des canaux de commande de liaison montante physique (PUCCH) se chevauchant dans un intervalle ou des PUCCH et des PUSCH se chevauchant qui sont mappés sur un même point TRP dans un scénario multi-TRP et qui sont mappés sur au moins deux points TRPs différents dans le scénario multi-TRP. Par exemple, dans un scénario multi-TRP comprenant deux points TRP, l'UE peut éliminer le chevauchement de ces canaux de liaison montante pour chacun des deux TRPs individuellement et peut en outre éliminer le chevauchement de ces canaux de liaison montante entre les deux points TRPs.
