Method for transmitting and receiving shared channel in wireless communication system, and device supporting same
View Patent ↗In a method for transmitting and receiving a shared channel in a wireless communication system, the method performed by a terminal is characterized by comprising: a step for receiving, from a base station, first resource information for transmitting and receiving a shared channel; and a step for receiving, from the base station, the shared channel on a first resource determined on the basis of the first resource information or transmitting, to the base station, the shared channel on the first resource.
1. A method for receiving a shared channel by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, first resource information on a control channel,
wherein the first resource information includes information related to a symbol length and a relative start symbol index; and
receiving, from the base station, a shared channel on a first resource determined based on the first resource information,
wherein a start symbol index of the first resource is determined based on the relative start symbol index and a reference symbol index,
wherein the reference symbol index is determined based on a resource allocated for a monitoring of the control channel,
wherein the first resource is determined based on a first subcarrier spacing (SCS) for the control channel and a second SCS for the shared channel.
2. The method of claim 1 ,
wherein the control channel is included in a first cell,
wherein the shared channel is included in a second cell.
3. The method of claim 1 ,
wherein the reference symbol index is an index of an earliest symbol among symbols for the monitoring of the control channel.
4. The method of claim 3 ,
wherein, the first SCS and the second SCS are the same.
5. The method of claim 1 ,
wherein the first resource information further includes information related to a position of a demodulation-reference signal (DM-RS).
6. The method of claim 5 ,
wherein one or more symbols to which the DM-RS is mapped include an earliest symbol of the first resource.
7. A terminal for receiving a shared channel in a wireless communication system, the terminal comprising:
a transceiver;
a processor; and
a memory connected to the processor and configured to store instructions for operations executed by the processor, wherein the operations comprise:
receiving, from a base station, first resource information on a control channel,
wherein the first resource information includes information related to a symbol length and a relative start symbol index; and
receiving, from the base station, a shared channel on a first resource determined based on the first resource information,
wherein a start symbol index of the first resource is determined based on the relative start symbol index and a reference symbol index,
wherein the reference symbol index is determined based on a resource allocated for a monitoring of the control channel,
wherein the first resource is determined based on a first subcarrier spacing (SCS) for the control channel and a second SCS for the shared channel.
8. The terminal of claim 7 ,
wherein the control channel is included in a first cell,
wherein the shared channel is included in a second cell.
9. The terminal of claim 7 ,
wherein the reference symbol index is an index of an earliest symbol among symbols for monitoring the control channel.
10. The terminal of claim 9 ,
wherein, the first SCS and the second SCS are the same.
11. The terminal of claim 7 ,
wherein the first resource information further includes information related to a position of a demodulation-reference signal (DM-RS).
12. The terminal of claim 11 ,
wherein one or more symbols to which the DM-RS is mapped include an earliest symbol of the first resource.
13. A method for transmitting a shared channel by a base station in a wireless communication system, the method comprising:
transmitting, to a terminal, first resource information for reception of a shared channel on a control channel,
wherein the first resource information includes information related to a symbol length and a relative start symbol index in a time domain resource for reception of the shared channel; and
transmitting, to the terminal, the shared channel on a first resource determined based on the first resource information,
wherein a start symbol index of the first resource is determined based on the relative start symbol index and a reference symbol index,
wherein the reference symbol index is determined based on a resource allocated for a monitoring of the control channel,
wherein the first resource is determined based on a first subcarrier spacing (SCS) for the control channel and a second SCS for the shared channel.
14. The method of claim 13 ,
wherein the control channel is included in a first cell,
wherein the shared channel is included in a second cell.
15. The method of claim 13 ,
wherein the reference symbol index is an index of an earliest symbol among symbols for monitoring the control channel.
16. The method of claim 15 ,
wherein, the first SCS and the second SCS are the same.
17. The method of claim 13 ,
wherein the first resource information further includes information related to a position of a demodulation-reference signal (DM-RS).
18. The method of claim 17 ,
wherein one or more symbols to which the DM-RS is mapped include an earliest symbol of the first resource.
