  • Publication number: 20220216964
    Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for a single downlink control information (DCI) signal that supports multi-transmission reception point (TRP) transmissions from different TRPs (e.g., different 5G Node Bs or different antenna panels.) A user equipment (UE) receives a single DCI signal that includes a first transmission configuration indicator (TCI) state of a first TRP, a second TCI state of a second TRP, and a demodulation reference signal (DMRS) port indication value. The UE uses the DMRS port indication value to determine a first DMRS port and a first code division multiplexing (CDM) group of the first TCI state and a second DMRS port and a second CDM group of the second TCI state. The UE receives a multi-Physical Downlink Shared Channel (PDSCH) signal that includes multi-TRP transmissions, and uses the above determinations to decode data from the first and/or the second TCI states.

  • Publication number: 20220077982
    Abstract: The present disclosure provides systems and methods for mapping transmission configuration indication (TCI) states to demodulation reference signal (DMRS) ports groups in a wireless network. For instance, a TCI state to DMRS ports group mapping of a user equipment (UE) can be determined. Each DMRS port in a DMRS ports group shares a quasi-co-location (QCL) assumption. The TCI state to DMRS ports group mapping comprises multiple TCI state groups. The TCI state to DMRS ports group mapping corresponds each TCI state group to one or more DMRS ports groups. A TCI state group from the DMRS ports group mapping can be selected for the UE. Data indicative of the selected TCI state group and the corresponding one or more DMRS ports groups can be provided to the UE based at least in part on the TCI state group from the DMRS ports group mapping.
