  • Multi-antenna technology is a key technology in the 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system and NR (New Radio) system. Additional spatial degrees of freedom are obtained by configuring multiple antennas at communication nodes, such as base stations or UEs (User Equipment).

The degree of freedom provided by multiple antenna systems can be exploited to improve transmission reliability and/or throughput. When multiple antennas belong to multiple TRPs (Transmitter Receiver Points, transmitting and receiving nodes)/panels (antenna panels), additional diversity gain can be obtained by utilizing the spatial differences between different TRPs/panels.

Abstract

Est divulgué dans la présente demande un procédé utilisé dans un nœud pour une communication sans fil, ainsi qu'un appareil. Un premier nœud reçoit au moins une signalisation et envoie un premier signal donné dans un premier groupe de symboles donné, ou abandonne la transmission du premier signal donné dans au moins une partie des symboles dans le premier groupe de symboles donné. Le premier signal donné est un premier signal ou un second signal; le premier signal est associé à un premier ensemble de ressources de signal de référence; et le second signal est associé à un second ensemble de ressources de signal de référence. Le premier ensemble de ressources de signal de référence correspond à une première avance temporelle, et le second ensemble de ressources de signal de référence correspond à une seconde avance temporelle. La première avance temporelle et la seconde avance temporelle sont utilisées pour déterminer s'il faut abandonner la transmission du premier signal donné dans au moins une partie des symboles dans le premier groupe de symboles donné. Le procédé prend en charge une transmission multi-faisceaux/TRP/panneaux de liaison montante d'après différentes TA, et les performances de transmission en liaison montante sont améliorées.
