Abstract: Disclosed herein are system, method, and computer program product embodiments for enhancement in configured grant transmission. An embodiment operates by receiving a configured grant (CG) configuration message configuring a plurality of CG physical uplink shared channel (PUSCH) transmission occasions (TOs) within a CG period. Next, the embodiment receives an information element indicating a time division duplexing (TDD) uplink-downlink (UL-DL) slot configuration. The embodiment then determines whether a particular CG PUSCH TO of the plurality of CG PUSCH TOs overlaps with a DL slot indicated by the TDD UL-DL slot configuration. Finally, in response to a determination that the particular CG PUSCH TO overlaps with the DL slot, the embodiment skips utilizing the particular CG PUSCH TO.

Abstract: Approaches are described for receiving downlink signals simultaneously where analog beamforming is being used to increase the link budget between the base station and user equipment (UE). Alternatives within these approaches include the UE determining the synchronization signal block (SSB) to receive when there are multiple SSBs from different cells in a slot, and determining whether there are other signals in the same symbols with the selected SSB based on the type of signal and the SSB's functionality. In the case where there are another downlink signals channel state information-reference signal (CSI-RS) or physical downlink shared channel (PDSCH) from another cell, the UE selects the corresponding quasi co-location (QCL) assumption to receive the signals. Optionally, the UE can report whether it can support one or two QCL-TypeD at a time and whether it supports SSBs in different cells multiplexed in overlapped symbols.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for a network to use Doppler shift pre-compensation values for communicating Tracking Reference Signal (TRS) to a user equipment (UE) and for implementing mechanisms for triggering the UE to measure the Doppler shift pre-compensated TRS. Some aspects of this disclosure relate to a base station including a processor that determines a Doppler shift pre-compensation value associated with the UE in response to determining that the UE is moving with a speed greater than a threshold. The processor further generates an aperiodic Tracking Reference Signal (AP-TRS) or a semi persistent TRS (SP-TRS) for the UE. The AP-TRS or the SP-TRS is decoupled from a periodic TRS (P-TRS). The processor further transmits the AP-TRS or the SP-TRS to the UE. The AP-TRS or the SP-TRS can be used for time and frequency synchronization.
