Abstract: Transmission of uplink demodulation reference signals (DMRSs) may be dynamically adapted for mobile devices. Downlink control information (DCI) that schedules uplink transmission (s) of the mobile device may include an information element (IE) corresponding to a DMRS to be transmitted by the UE during the uplink transmission (s). The IE enables the mobile device to determine when to transmit DMRSs during the scheduled uplink transmission (s). The mobile device may identify a corresponding DMRS pattern indicated by the IE, with the DMRS pattern defining how many DMRSs to transmit during the uplink transmission (s), how many DMRSs to transmit in a given time interval (TTI) bundle in the uplink transmission (s), how many DMRSs to transmit in a given repetition of the TTI bundle, and/or where the relative position (s) of the DMRSs are within the given repetition and the given TTI bundle. The DMRS patterns may be configured for the mobile device via higher layer signaling or may be hard-coded.

Abstract: A user equipment (UE) may establish communication with a plurality of transmission reception points (TRPs) and determine one or more beam failures associated with a first or second TRP based on reference signals received from the first and second TRPs. The UE may then transmit a scheduling request requesting resources for indicating the beam failures associated with the first TRP or second TRPs. Upon receiving a response to the scheduling request allocating resources, the UE may then transmit, using allocated resources, a beam failure indication of the first one or more beam failures associated with the first TRP or second TRP. After receiving a beam failure response from the first or second TRP, the UE may then communicate with the first TRP and the second TRP using one or more new beams based on the beam failure indication and the beam failure response.

Abstract: A user equipment (UE) associated with a non-terrestrial network (NTN) is disclosed. The UE comprises a processor configured to determine a first time offset, based on processing a timing offset indication signal comprising the first time offset or an associated parameter, received from a base station. In some embodiments, the first time offset is indicative of a time delay in downlink (DL) to uplink (UL) interaction between the UE and the base station. The processor is further configured to determine a second time offset, based on processing a subsequent timing offset indication signal comprising the second time offset or an associated parameter, received from the base station at a subsequent time instance. In some embodiments, the processor is further configured to update the first time offset with the second time offset.

Abstract: A method and apparatus of a device that determines an occurrence of the DL SPS or the UL CG to determine a periodicity of a packet generation is described. In an exemplary embodiment, the method receives a configuration for a downlink (DL) Semi-Persistent Scheduling (SPS) or an uplink (UL) Configured Grant (CG). The configuration includes an indication of non-integer periodicity of the DL SPS or the UL CG. Additionally, the method determines an occurrence of the DL SPS or the UL CG based on the received configuration for the DL SPS or the UL CG to determine a periodicity of a packet generation. Thereafter, the method transmits or receives data based on the configuration for the DL SPS or the UL CG.
