Abstract
An operation method of a terminal in a communication system includes receiving a message from a base station, the message including physical random access channel (PRACH) configuration information indicating a PRACH slot; determining a start symbol to which a PRACH is mapped among symbols constituting the PRACH slot based on a type of the PRACH slot; mapping the PRACH from the start symbol in the PRACH slot; and transmitting the PRACH mapped to the PRACH slot to the base station.

An operation method of a terminal in a communication system, the operation method comprising:
- receiving a message from a base station, the message including physical random access channel (PRACH) configuration information indicating a PRACH slot;
- determining a start symbol to which a PRACH is mapped among symbols constituting the PRACH slot based on a type of the PRACH slot;
- mapping the PRACH from the start symbol in the PRACH slot;
- and
- transmitting the PRACH mapped to the PRACH slot to the base station.
An operation method of a base station in a communication system, the operation method comprising:
- configuring a physical random access channel (PRACH) configuration period;
- configuring a PRACH slot located in the PRACH configuration period;
- and
- transmitting a message including information indicating the PRACH configuration period and the PRACH slot.
A terminal in a communication system, the terminal comprising a processor and a memory storing at least one instruction executed by the processor, wherein the at least one instruction is configured to:
- receive a message from a base station, the message including physical random access channel (PRACH) configuration information indicating a PRACH slot;
- determine a start symbol to which a PRACH is mapped among symbols constituting the PRACH slot based on a type of the PRACH slot;
- map the PRACH from the start symbol in the PRACH slot;
- and
- transmit the PRACH mapped to the PRACH slot to the base station.
