Method for performing uplink transmission through frequency hopping in wireless communication system and device therefor
A method for a user equipment (UE) to perform an uplink transmission through a frequency hopping in a wireless communication system is disclosed. More specifically, the method includes receiving uplink (UL)-downlink (DL) configuration information from a base station; and performing the uplink transmission through the frequency hopping for each non-slot on non-slots that are repeated at least two times within one slot based on the UL-DL configuration information, wherein the non-slot is a scheduling unit with a smaller time interval than the one slot.
1. A method of transmitting, by a user equipment (UE), a physical uplink shared channel (PUSCH) through a frequency hopping in a wireless communication system, the method comprising:
receiving uplink (UL)-downlink (DL) configuration information from a base station; and
repeatedly transmitting, to the base station, the PUSCH through the frequency hopping for each non-slot on non-slots based on the UL-DL configuration information,
wherein the frequency hopping is performed based on whether non-slot is even-numbered non-slot or odd-numbered non-slot without considering one or more invalid resources.
2. The method of claim 1 , wherein the non-slot is a scheduling unit with a time duration that is smaller than one slot.
3. The method of claim 1 , wherein a scheduling unit of the non-slot is configured based on at least one of a subcarrier spacing or a number of symbols included in the scheduling unit.
4. The method of claim 1 , wherein the non-slot is used for ultra reliable and low latency communication (URLLC), an unlicensed band or a millimeter wave.
5. The method of claim 1 , wherein based on a resource for the PUSCH being not included in a bandwidth part (BWP) by the frequency hopping, the resource that is not included in the BWP is offset by a predetermined resource block (RB) offset or is not used for the PUSCH.
6. The method of claim 5 , wherein the offset by the predetermined RB offset for the resource that is not included in the BWP is determined depending on a type of waveform configured for the PUSCH.
7. The method of claim 6 , wherein the waveform is cyclic prefix (CP)-orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-s-OFDM).
8. The method of claim 7 , wherein based on the waveform being the CP-OFDM, the resource that is not included in the BWP is offset by the predetermined RB offset.
9. A user equipment (UE) configured to perform a physical uplink shared channel (PUSCH) transmission through a frequency hopping in a wireless communication system, the UE comprising:
at least one transceiver;
at least one processor; and
at least one computer-readable memory operably connectable to the at least one processor and storing instructions that, based on being executed by the least one processor, perform operations comprising:
receiving uplink (UL)-downlink (DL) configuration information from a base station; and
repeatedly transmitting, to the base station, the PUSCH through the frequency hopping for each non-slot on non-slots based on the UL-DL configuration information,
wherein the frequency hopping is performed based on whether non-slot is even-numbered non-slot or odd-numbered non-slot without considering one or more invalid resources.
10. The UE of claim 9 , wherein the non-slot is a scheduling unit with a time duration that is smaller than one slot.
11. The UE of claim 9 , wherein a scheduling unit of the non-slot is configured based on at least one of a subcarrier spacing or a number of symbols included in the scheduling unit.
12. The UE of claim 9 , wherein the non-slot is used for ultra reliable and low latency communication (URLLC), an unlicensed band or a millimeter wave.
13. The UE of claim 9 , wherein based on a resource for the PUSCH being not included in a bandwidth part (BWP) by the frequency hopping, the resource that is not included in the BWP is offset by a predetermined resource block (RB) offset or is not used for the PUSCH.
14. The UE of claim 13 , wherein the offset by the predetermined RB offset for the resource that is not included in the BWP is determined depending on a type of waveform configured for the PUSCH.
15. The UE of claim 14 , wherein based on the waveform being the CP-OFDM, the resource that is not included in the BWP is offset by the predetermined RB offset.
16. The method of claim 1 , wherein the one or more invalid resources are one or more symbols.
17. The UE of claim 9 , wherein the one or more invalid resources are one or more symbols.
