Publication number: 20230284265Abstract: Systems, methods, apparatuses, and computer program products for indicating network node fixed frame period (FFP) or UE FFP. A UE may transmit an uplink (UL) signal at a start of a UE FFP. A network node may respond by allocating UL resource(s) for subsequent UE transmission(s). The network node may implicitly signal, in Downlink Control Information (DCI), whether a UL transmission is to be transmitted based on assuming a UE FFP or a network node FFP for the UL transmission. The UE may make this assumption based on a cyclic prefix (CP) extension indication in DCI. For example, for certain CP extensions, the UE may determine to transmit the UL transmission according to the UE FFP. Otherwise, the UE may determine to transmit the UL transmission according to a network node FFP.Type: ApplicationFiled: June 21, 2021Publication date: September 7, 2023Inventors: Claudio ROSA, Timo LUNTTILA, Kari HOOLI, Karol SCHOBER
