Method and apparatus for repeated transmission and reception in wireless communication system
The present disclosure relates to a method of a terminal in a wireless communication system. The method may include: determining a plurality of temporally sequential uplink transmission resources to repeatedly transmit a transmission block through configured grant-based uplink transmission; identifying a first uplink transmission resource corresponding to first initial transmission for the transmission block from among the determined plurality of uplink transmission resources; when the first initial transmission is cancelled, identifying a second uplink transmission resource corresponding to second initial transmission for the transmission block based on uplink transmission resource candidates following the identified first uplink transmission resource from among the plurality of uplink transmission resources; and performing the second initial transmission through the identified second uplink transmission resource.
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, configuration information associated with a redundancy version (RV) pattern to be applied to a transport block repetition for configured grant-based uplink transmissions;
identifying a first uplink transmission resource for first initial transmission of the transport block repetition, based on the RV pattern, the first uplink transmission resource corresponding to an RV of zero;
in case that the first initial transmission associated with the first uplink transmission resource corresponding to the RV of zero is cancelled, identifying a second uplink transmission resource for a second initial transmission of the transport block repetition, wherein the second uplink transmission resource follows the first uplink transmission resource in a time domain, and wherein the second uplink transmission resource corresponds to an RV of zero or non-zero; and
performing the configured grant-based uplink transmissions related to the transport block repetition, based on the second uplink transmission resource.
2. The method of claim 1 , wherein the second uplink transmission resource comprises an uplink transmission resource immediately following the first uplink transmission resource.
3. The method of claim 2 , wherein a redundancy version corresponding to the uplink transmission resource immediately following the first uplink transmission resource is set to non-zero.
4. The method of claim 1 , wherein the second uplink transmission resource comprises a first uplink transmission resource with a redundancy version set to zero.
5. The method of claim 1 , wherein the first initial transmission is cancelled by an uplink transmission cancellation indicator.
6. The method of claim 1 , wherein the first initial transmission is cancelled when at least one of symbols included in the first uplink transmission resource is indicated as a downlink symbol or a flexible symbol by a slot format indicator.
7. The method of claim 1 , wherein the first initial transmission is cancelled when at least one symbol included in the first uplink transmission resource overlaps at least one symbol of an uplink transmission resource based on scheduling information for uplink data.
8. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
at least one processor coupled with the transceiver and configured to;
receive, from a base station, configuration information associated with a redundancy version (RV) pattern to be applied to a transport block repetition for configured grant-based uplink transmissions,
identify a first uplink transmission resource for first initial transmission of the transport block repetition, based on the RV pattern, the first uplink transmission resource corresponding to an RV of zero,
in case that the first initial transmission associated with the first uplink transmission resource corresponding to the RV of zero is cancelled, identify a second uplink transmission resource for a second initial transmission of the transport block repetition, wherein the second uplink transmission resource follows the first uplink transmission resource in a time domain, and wherein of the second uplink transmission resource corresponds to an RV of zero or non-zero, and
perform the configured grant-based uplink transmissions related to the transport block repetition, based on the second uplink transmission resource.
9. The terminal of claim 8 , wherein the second uplink transmission resource comprises an uplink transmission resource immediately following the first uplink transmission resource.
10. The terminal of claim 9 , wherein a redundancy version corresponding to the uplink transmission resource immediately following the first uplink transmission resource is set to non-zero.
11. The terminal of claim 8 , wherein the second uplink transmission resource comprises an uplink transmission resource with a redundancy version set to zero.
12. The terminal of claim 8 , wherein the first initial transmission is cancelled by at least one of an uplink transmission cancellation indicator or a slot format indicator.
13. The terminal of claim 12 , wherein the first initial transmission is cancelled when at least one of symbols included in the first uplink transmission resource is indicated as a downlink symbol or a flexible symbol by the slot format indicator.
