Abstract
The present disclosure describes methods, systems and devices for configuring signal resource for physical random access channel (PRACH). One method includes configuring, by a base station, signal resource for a PRACH by mapping, by the base station, a PRACH slot pattern with a pattern parameter. Another method includes configuring, by a user equipment, signal resource for a PRACH by mapping, by the user equipment, a PRACH slot pattern with a pattern parameter.
Claims20
A method for wireless communication, comprising:
- configuring, by a base station, signal resource for a physical random access channel (PRACH) by:
- determining, by the base station, a PRACH slot pattern with a pattern parameter based on a PRACH subcarrier spacing (SCS) and a specific time duration,
- wherein:
- in response to a maximum number of PRACH slots in the specific time duration being 8 and the PRACH slot pattern comprising one PRACH slot, the pattern parameter comprises {7};
- and
- in response to a maximum number of PRACH slots in the specific time duration being 8 and the PRACH slot pattern comprising two PRACH slots, the pattern parameter comprises {3, 7}.

A method for wireless communication, comprising:
- determining, by a user equipment (UE), signal resource for a physical random access channel (PRACH) by:
- determining, by the UE, a PRACH slot pattern with a pattern parameter based on a PRACH subcarrier spacing (SCS) and a specific time duration,
- wherein:
- in response to a maximum number of PRACH slots in the specific time duration being 8 and the PRACH slot pattern comprising one PRACH slot, the pattern parameter comprises {7};
- and
- in response to a maximum number of PRACH slots in the specific time duration being 8 and the PRACH slot pattern comprising two PRACH slots, the pattern parameter comprises {3, 7}.

A wireless network node comprising:
- a memory storing instructions;
- and
- a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the wireless network node to perform:
- configuring signal resource for a physical random access channel (PRACH) by:
- determining a PRACH slot pattern with a pattern parameter based on a PRACH subcarrier spacing (SCS) and a specific time duration,
- wherein:
- in response to a maximum number of PRACH slots in the specific time duration being 8 and the PRACH slot pattern comprising one PRACH slot, the pattern parameter comprises {7};
- and
- in response to a maximum number of PRACH slots in the specific time duration being 8 and the PRACH slot pattern comprising two PRACH slots, the pattern parameter comprises {3, 7}.
