Title (EN) RANDOM ACCESS CHANNEL ENHANCEMENTS FOR NARROWBAND SYSTEMS
(FR) AMÉLIORATIONS DE CANAL D'ACCÈS ALÉATOIRE POUR SYSTÈMES À BANDE ÉTROITE
Abstract:
(EN) Aspects of the present disclosure provide techniques to enable random access channel (RACH) enhancements over previously known techniques for narrowband (e.g., narrowband Internet-of-Things (NB-IoT) ) communications systems. An example method includes receiving a first allocation of frequency resources for a first period for receiving a downlink (DL) transmission or transmitting an uplink (UL) transmission, and postponing transmission of a random access channel (RACH) by the UE during the period.
(FR) Des aspects de la présente invention concernent des techniques en vue de permettre des améliorations de canal d'accès aléatoire (RACH) par rapport à des techniques connues jusqu'à présent pour des systèmes de communication à bande étroite (par exemple, Internet des objets à bande étroite (NB-IoT)). Un procédé donné à titre d'exemple consiste à recevoir une première attribution de ressources de fréquence pour une première période pour recevoir une transmission de liaison descendante (DL) ou transmettre une transmission de liaison montante (UL), et à différer la transmission d'un canal d'accès aléatoire (RACH) par l'UE pendant la période.
