摘要： A user equipment (UE) for receiving control information in a wireless communication system includes a transceiver configured to receive a synchronization signal/physical broadcasting channel (SS/PBCH) block of an index i from a BS, wherein SS/PBCH block comprises a PBCH carrying master information block (MIB). The UE includes a processor configured to for the SS/PBCH block of the index i, determine a slot index n0 as a sum of an offset value and └i*M┘. The offset value is determined based on a first value O determined according to the index indicated in the MIB, wherein the index configures PDCCH monitoring occasions, and a second value μ indicated in the MIB, wherein the second value μ represents a subcarrier spacing configuration, wherein M is a positive number determined according to the index indicated in the MIB, and cause the transceiver to decode a PDCCH in the slot index n0.

摘要： Apparatuses and methods for synchronization signal (SS) block index and timing indication in wireless communication systems. A method of operating a user equipment (UE) includes receiving, from a base station (BS), sets of higher-layer configuration information. When configured for mobility measurement on SS and physical broadcast channel (PBCH) (SS/PBCH) blocks, the UE identifies, based on one of the sets of higher-layer configuration information, a first set of SS/PBCH blocks configured for the mobility measurement; and measures and reports mobility measurement quantities for the first set of SS/PBCH blocks. When configured for receiving a physical downlink shared channel (PDSCH), the UE identifies, based on another of the sets of higher-layer configuration information, a second set of SS/PBCH blocks configured for the UE; and receives the PDSCH with rate matching around a SS/PBCH block included in the second set of SS/PBCH blocks.
