Abstract
Apparatuses, systems, and methods for downlink control resources sets and RACH procedures during initial access in wireless communication, e.g., in 5G NR systems and beyond, including methods for CORESET #0 configuration, SSB/CORESET #0 multiplexing pattern 1 for mixed SCS, time-domain ROs determination for 480 kHz/960 kHz SCSs, and RA-RNTI determination for 480 kHz/960 kHz SCSs.
Claims20
A method for initial access communications, comprising:
- determining, based on a configuration index included in a higher layer parameter, positions of random access channel (RACH) occasion (RO) slots with a first sub-carrier spacing (SCS) within a physical RACH (PRACH) slot of a reference sub-carrier spacing (SCS);
- and
- determining, based on a total number of time domain ROs in the PRACH slot of the reference SCS, a distribution of the ROs with the first SCS.
A processor, comprising:
- a memory;
- and
- processing circuitry in communication with the memory and configured to:
- determine, based on a configuration index included in a higher layer parameter, positions of random access channel (RACH) occasion (RO) slots with a first sub-carrier spacing (SCS) within a physical RACH (PRACH) slot of a reference sub-carrier spacing (SCS);
- and
- determine, based on a total number of time domain ROs in the PRACH slot of the reference SCS, a distribution of the ROs with the first SCS.
A non-transitory computer readable memory medium storing program instructions executable by a processor to:
- determining, based on a configuration index included in a higher layer parameter, positions of random access channel (RACH) occasion (RO) slots with a first sub-carrier spacing (SCS) within a physical RACH (PRACH) slot of a reference sub-carrier spacing (SCS);
- and
- determining, based on a total number of time domain ROs in the PRACH slot of the reference SCS, a distribution of the ROs with the first SCS.
