Method and apparatus for transmitting uplink channel in wireless communication system
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a wireless communication system comprises determining multiple slots for a PUSCH transmission; identifying a redundancy version for the PUSCH transmission; and transmitting a transport block (TB) across the multiple slots determined for the PUSCH transmission, wherein a single value of the redundancy version is applied on the TB across the multiple slots.
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving information indicating a number of slots for a transport block (TB) processing over multi-slot (TBoMS);
determining multiple slots for a physical uplink shared channel (PUSCH) of the TBoMS, based on the information;
identifying a redundancy version for the PUSCH of the TBoMS;
performing rate matching of code blocks associated with the TBoMS; and
transmitting the PUSCH of the TBoMS, based on the multiple slots,
wherein a value of the redundancy version is applied on the TBOMS, and
wherein rate matching of a code block for a second slot among the multiple slots starts consecutively from an end of rate matching of a code block for a first slot among the multiple slots.
2. The method of claim 1 , wherein:
the multiple slots comprise at least one of consecutive slots or nonconsecutive slots, and
transmission occasions corresponding to the consecutive slots are determined to be the same for applying the value of the redundancy version to the TBoMS.
3. The method of claim 1 , further comprising:
identifying a configuration for a PUSCH repetition type,
wherein the redundancy version is identified based on the configuration.
4. The method of claim 1 , further comprising:
determining a size of the TBoMS based on the number of the slots.
5. A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a terminal, information indicating a number of slots for a transport block (TB) processing over multi-slot (TBoMS); and
receiving, from the terminal, a physical uplink shared channel (PUSCH) of the TBoMS, based on multiple slots,
wherein a value of a redundancy version for the PUSCH of the TBoMS is applied on the TBOMS,
wherein the multiple slots are determined based on the information,
wherein code blocks associated with the TBoMS are rate matched, and
wherein rate matching of a code block for a second slot among the multiple slots starts consecutively from an end of rate matching of a code block for a first slot among the multiple slots.
6. The method of claim 5 , further comprising:
wherein a size of the TBoMS is determined based on the number of the slots.
7. The method of claim 5 , wherein:
the multiple slots comprise at least one of consecutive slots or nonconsecutive slots; and
transmission occasions corresponding to the consecutive slots are determined to be the same for applying the value of the redundancy version to the TBoMS.
8. The method of claim 5 , further comprising:
transmitting, to the terminal, a configuration for a PUSCH repetition type,
wherein the redundancy version is identified based on the configuration.
9. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a processor operably coupled with the transceiver, the processor configured to:
receive information indicating a number of slots for a transport block (TB) processing over multi-slot (TBoMS),
determine multiple slots for a physical uplink shared channel (PUSCH) of the TBoMS, based on the information,
identify a redundancy version for the PUSCH of the TBoMS,
perform rate matching of code blocks associated with the TBoMS, and
transmit the PUSCH of the TBoMS based on the multiple slots,
wherein a value of the redundancy version is applied on the TBOMS, and
wherein rate matching of a code block for a second slot among the multiple slots starts consecutively from an end of rate matching of a code block for a first slot among the multiple slots.
10. The terminal of claim 9 , wherein:
the processor is further configured to:
determine a size of the TBoMS based on the number of the slots.
11. The terminal of claim 9 , wherein:
the multiple slots comprise at least one of consecutive slots or nonconsecutive slots; and
transmission occasions corresponding to the consecutive slots are determined to be the same for applying the value of the redundancy version to the TBoMS.
12. The terminal of claim 9 , wherein:
the processor is further configured to:
identify a configuration for a PUSCH repetition type, and
the redundancy version is identified based on the configuration.
13. A base station in a wireless communication system, the base station comprising:
a transceiver; and
a processor operably coupled with the transceiver, the processor configured to:
control the transceiver to transmit, to a terminal, information indicating a number of slots for a transport block (TB) processing over multi-slot (TBoMS), and
control the transceiver to receive, from the terminal, a physical uplink shared channel (PUSCH) of the TBoMS, based on multiple slots,
wherein a value of a redundancy version for the PUSCH of the TBoMS is applied on the TBoMS,
wherein the multiple slots are determined based on the information,
wherein code blocks associated with the TBoMS are rate matched, and
wherein rate matching of a code block for a second slot among the multiple slots starts consecutively from an end of rate matching of a code block for a first slot among the multiple slots.
14. The base station of claim 13 , wherein:
the processor is further configured to:
control the transceiver to transmit, to the terminal, a configuration for a PUSCH repetition type,
a size of the TBoMS is determined based on the number of the slots; and
the redundancy version is identified based on the configuration.
