  • Publication number: 20240121041
    Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical down-link control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCII. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.
