Method and device for transmitting and receiving signal in wireless communication system
One embodiment of the present invention relates to a method and a device for transmitting and receiving a signal in a wireless communication system, the method comprising the steps of: performing a random access procedure; monitoring a physical downlink control channel (PDCCH) for an ON duration on the basis of a configured discontinuous reception (DRX) operation after performing the random access procedure; and operating an inactivity timer on the basis of the successfully received PDCCH for the ON duration. During the random access procedure, a random access preamble is transmitted in one or two physical random access channel (PRACH) slots. The one or two PRACH slots are determined from among N slots corresponding to a reference slot. A subcarrier spacing (SCS) setting value for the reference slot may be 2 on the basis of the SCS setting value applied to the N slots being 5 or 6.
1. A method for transmitting and receiving signals by a terminal in a wireless communication system, the method comprising:
performing a random access procedure;
after performing the random access procedure, monitoring a Physical Downlink Control Channel (PDCCH) for an on duration based on configured Discontinuous Reception (DRX); and
based on the PDCCH successfully received for the on duration, operating an inactivity timer,
wherein, during the random access procedure, a random access preamble is transmitted in one or two Physical Random Access Channel (PRACH) slots,
wherein the one or two PRACH slots are determined among N slots corresponding to a reference slot,
wherein, based on a SubCarrier Spacing (SCS) configuration value applied to the N slots being 5 or 6, an SCS configuration value for the reference slot is 2.
2. The method of claim 1 , wherein, based on a number of PRACH slots in the reference slot being 1, a value for the one PRACH slot is N−1.
3. The method of claim 1 , wherein, based on a number of PRACH slots in the reference slot not being 1, values for the two PRACH slots are N/2−1 and N−1.
4. The method of claim 1 , wherein, based on a number of PRACH slots in the reference slot not being 1, values for the two PRACH slots are N−1 and N−2.
5. A terminal for transmitting and receiving signals in a wireless communication system, the terminal comprising:
at least one transceiver;
at least one processor; and
at least one memory operatively connected to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform a specific operation,
wherein the specific operation comprises:
performing a random access procedure;
after performing the random access procedure, monitoring a Physical Downlink Control Channel (PDCCH) for an on duration based on configured Discontinuous Reception (DRX); and
based on the PDCCH successfully received for the on duration, operating an inactivity timer,
wherein, during the random access procedure, a random access preamble is transmitted in one or two Physical Random Access Channel (PRACH) slots,
wherein the one or two PRACH slots are determined among N slots corresponding to a reference slot,
wherein, based on a SubCarrier Spacing (SCS) configuration value applied to the N slots being 5 or 6, an SCS configuration value for the reference slot is 2.
6. The terminal of claim 5 , wherein, based on a number of PRACH slots in the reference slot being 1, a value for the one PRACH slot is N−1.
7. The terminal of claim 5 , wherein, based on a number of PRACH slots in the reference slot not being 1, values for the two PRACH slots are N/2−1 and N−1.
8. The terminal of claim 5 , wherein, based on a number of PRACH slots in the reference slot not being 1, values for the two PRACH slots are N−1 and N−2.
