  • Publication number: 20250227694
    Abstract: An apparatus and system of supporting simultaneous transmission over multi-panel (STxMP) uplink (UL) transmissions are described. At least one downlink control information (DCI) is used to schedule STxMP UL transmission to multiple transmit-receive points (TRPs). The DCI indicates whether time domain (TD) repetition is to be applied, in addition to time domain and/or frequency domain resource location for different multiplexing schemes. Aperiodic-channel state information (A-CSI) or semi-persistent CSI (SP-CSI) multiplexing is multiplexed within one or more of the repetitions. One or more sounding reference signal (SRS) resource indication (SRI) fields in the DCI indicate the SRS resources to use for the transmission. Mechanisms of physical uplink control channel (PUCCH) resource configuration are described for STxMP operation.

  • Patent number: 12238025
    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.

  • Patent number: 12238029
    Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical downlink 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.
