  • PUSCH1 of UE1 is transmitted by UE2, and PUCCH1 of UE1 is transmitted by UE1. In this way, UE1 still only transmits one uplink channel.
  • PUCCH1 of UE1 is transmitted by UE2, and PUSCH1 of UE1 is transmitted by UE1. In this way, UE1 still only transmits one uplink channel.
  • Option 7 Between the two channels of PUCCH1 and PUSCH1, the channel with higher priority is transmitted by UE2, and the channel with lower priority is transmitted by UE1. In this way, UE1 still only transmits one uplink channel.
  • Option 8 Between the two channels of PUCCH1 and PUSCH1, the channel with higher priority is transmitted by UE1, and the channel with lower priority is transmitted by UE2. In this way, UE1 still only transmits one uplink channel.
  • the base station and UE agree to use one of the above methods; alternatively, the base station can configure UE to use one of the above methods.
  • the base station can receive PUCCH1 or PUSCH1 from UE1 and/or UE2 and perform reverse operations to obtain PUSCH1 and UCI in PUCCH1.

Abstract

La présente divulgation concerne des procédés, un système et des dispositifs pour générer et transmettre une demande de planification (SR) sous une transmission par agrégation d'équipement utilisateur (UE). Le procédé consiste à recevoir une configuration de demande de planification (SR) partagée, le premier UE et le second UE étant appariés pour la transmission par agrégation d'UE ; configurer des ressources de SR partagée correspondant à la configuration de SR partagée ; former des informations de SR selon un statut de condition planifié d'au moins l'un parmi le premier UE et le second UE ; déterminer une séquence de SR sur la base des informations de SR ; et transmettre la séquence de SR dans une ressource de SR parmi les ressources de SR partagée.
