Method for performing uplink transmission using preconfigured resource in wireless communication system, and device therefor
Disclosed is a method for performing preconfigured uplink resource (PUR) transmission by means of a PUR in a wireless communication system. The method performed by a terminal comprises the steps of: receiving information relating to PUR transmission from a base station; receiving information relating to a first paging SS from the base station; performing the PUR transmission to the base station; and receiving downlink control information (DCI) in accordance with the PUR transmission from the base station.
1. A method of transmitting, by a user equipment (UE), a physical uplink shared channel (PUSCH) using a preconfigured uplink resource (PUR) in a wireless communication system, the method comprising:
receiving, from a base station, PUR configuration information, wherein the PUR information includes information for the PUR and information for a PUR search space (SS);
receiving, from the base station, information for a paging SS; and
transmitting the PUSCH to the base station using the PUR,
wherein, based on subframes related to the paging SS including a subframe for the PUSCH, monitoring for the paging SS is not performed.
2. The method of claim 1 , wherein the subframe for the PUSCH is a subframe in which the UE transmits the PUSCH using the PUR.
3. The method of claim 1 , wherein the paging SS is a Type1-common search space.
4. The method of claim 1 , further comprising: receiving downlink control information (DCI) based on a transmission of the PUSCH.
5. The method of claim 4 , wherein the DCI includes feedback information for a PUSCH transmission using the PUR.
6. The method of claim 4 , wherein the DCI includes a cyclic redundancy check (CRC) scrambled by a preconfigured uplink resource-radio network temporary identifier (PUR-RNTI) and is received in the PUR SS.
7. The method of claim 1 , wherein a PUSCH transmission is performed in a radio resource control (RRC) idle state.
8. The method of claim 1 , wherein the wireless communication system supports a narrowband-internet of things (NB-IoT).
9. The method of claim 8 , wherein the PUSCH is a narrowband physical uplink shared channel.
10. A user equipment (UE) configured to transmit a physical uplink shared channel (PUSCH) using a preconfigured uplink resource (PUR) in a wireless communication system, the UE comprising:
a transceiver;
at least one processor; and
at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
receiving, from a base station, PUR configuration information, wherein the PUR information includes information for the PUR and information for a PUR search space (SS);
receiving, from the base station, information for a paging SS; and
transmitting the PUSCH to the base station using the PUR,
wherein, based on subframes related to the paging SS including a subframe for the PUSCH, monitoring for the paging SS is not performed.
11. The UE of claim 10 , wherein the subframe for the PUSCH is a subframe in which the UE transmits the PUSCH using the PUR.
12. The UE of claim 10 , wherein the paging SS is a Type1-common search space.
13. The UE of claim 10 , further comprising: receiving downlink control information (DCI) based on a transmission of the PUSCH.
14. The UE of claim 13 , wherein the DCI includes feedback information for a PUSCH transmission using the PUR.
15. The UE of claim 13 , wherein the DCI includes a cyclic redundancy check (CRC) scrambled by a preconfigured uplink resource-radio network temporary identifier (PUR-RNTI) and is received in the PUR SS.
16. The UE of claim 10 , wherein a PUSCH transmission is performed in a radio resource control (RRC) idle state.
17. The UE of claim 10 , wherein the wireless communication system supports a narrowband-internet of things (NB-IOT).
18. The UE of claim 10 , wherein the PUSCH is a narrowband physical uplink shared channel.
19. A base station configured to receive a physical uplink shared channel (PUSCH) using a preconfigured uplink resource (PUR) in a wireless communication system, the base station comprising:
a transceiver;
at least one processor; and
at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
transmitting, to a user equipment (UE), PUR configuration information, wherein the PUR information includes information for the PUR and information for a PUR search space (SS);
transmitting, to the UE, information for a paging SS; and
receiving the PUSCH from the UE using the PUR, wherein, based on subframes related to the paging SS including a subframe for the PUSCH, monitoring for the paging SS is not performed.
20. The base station of claim 19 , wherein the subframe for the PUSCH is a subframe in which the UE transmits the PUSCH using the PUR.
