Abstract
(EN)
Methods, systems, and devices for wireless communications are described that support uplink reporting techniques for multi transmission-reception point (TRP) transmissions. Various reporting configurations may be provided that allow for user equipment (UE) communications via multiple concurrent wireless connections with multiple TRPs. A UE may identify a reporting configuration and transmit a report (e.g., a buffer status report (BSR) or a power headroom report (PHR)) to one or more of the TRPs based on the identified reporting configuration. The multiple TRPs may have non-ideal backhaul connections and the reporting configuration may allow the UE to transmit separate reports to different TRPs. The different TRPs may then use the separate reports for corresponding communications with the UE. In cases where shared radio frequency spectrum is used for communications, a single channel access priority class (CAPC) for multiple TRPs may be determined for a contention-based channel access procedure.

La présente invention concerne des procédés, des systèmes et des dispositifs de communications sans fil, qui prennent en charge des techniques de rapport pour des transmissions de points de réception transmission (TRP) multiples. Diverses configurations de rapport peuvent être fournies qui permettent des communications d'équipement d'utilisateur (UE) par l'intermédiaire de connexions sans fil simultanées multiples comportant des TRP multiples. Un UE peut identifier une configuration de rapport et transmettre un rapport (par exemple, un rapport d'état de tampon (BSR) ou un rapport de marge de puissance (PHR)) à un ou plusieurs des TRP sur la base de la configuration de rapport identifié. Les TRP multiples peuvent avoir des connexions de liaison terrestre non idéales et la configuration de rapport peut permettre à l'UE de transmettre des rapports séparés à différents TRP. Les différents TRP peuvent ensuite utiliser les rapports séparés pour des communications correspondantes avec L'UE. Dans les cas où un spectre de fréquences radio partagées est utilisé pour des communications, une classe de priorité d'accès à canal (CAPC) unique destinée aux TRP multiples peut être déterminée pour une procédure d'accès au canal à base de contention.
