  • Patent number: 11265091
    Abstract: Embodiments of the present disclosure describe apparatuses, methods and machine-readable storage medium for Reference Signal Received Power (RSRP) measurement and allocation of Downlink (DL) transmission resources. A user equipment (UE) may detect a first Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block, and determine a subcarrier spacing (SCS) thereof. Mapping the first SS/PBCH block to OFDM symbols may be dependent on the SCS and a first SS/PBCH block index of the first SS/PBCH block. The UE may determine, based on the first SS/PBCH block and the SCS, a number of symbols of the slot or the slot pair for a CORESET for reception of a DL control channel associated with Remaining Minimum System Information (RMSI). The UE may decode the DL control channel in the CORESET. The DL control channel may be configured to indicate a DL data channel carrying the RMSI associated with the first SS/PBCH block.
