  • 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.

System information block (SIB) information is decoded based on the MIB information. The decoded PBCH information includes cyclic redundancy check (CRC) information. The scrambled PBCH payload and the unscrambled bit sequence can be verified based on the CRC information. The time information signaling includes one or more bits of a system frame number (SFN).
