Method and apparatus for transmitting uplink channel in wireless communication system
The disclosure relates to a communication technique for combining an IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety related services, and the like) based on 5G communication technologies and IoT-related technologies. The disclosure provides a method for improving the coverage of an uplink channel for uplink transmission.
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, configuration information for a physical uplink shared channel (PUSCH) transmission including;
first information on a number of slots for transport block processing over multi-slots (TBoMS) and second information on a repetition number of the TBoMS; and
identifying a total number of slots for repetition of TBoMS transmission based on the first information and the second information,
wherein the total number of slots is no larger than a preconfigured number of slots.
2. The method of claim 1 ,
wherein the total number of slots is obtained by multiplying the number of slots for the TBoMS, N, with the repetition number of the TBoMS, M, and
wherein the preconfigured number of slots is identified based on a maximum number of available slots for PUSCH repetition.
3. The method of claim 2 ,
wherein a slot is not counted in a number of N×M slots of the TBoMS transmission for a PUSCH repetition type A in case that count-based PUSCH repetition is configured, and
wherein the slot is unavailable for the TBoMS transmission.
4. The method of claim 1 ,
wherein the configuration information further includes at least one of information on a start symbol and a length of a symbol, or information on a PUSCH repetition type.
5. A method performed by a base station in a wireless communication system, the method comprising:
determining first information on a number of slots for transport block processing over multi-slots (TBoMS) and second information on a repetition number of the TBoMS; and
transmitting, to a terminal, configuration information for a physical uplink shared channel (PUSCH) transmission, the configuration information including the first information and the second information,
wherein the first information and the second information are associated with a total number of slots for repetition of TBoMS transmission, and
wherein the total number of slots is no larger than a preconfigured number of slots.
6. The method of claim 5 ,
wherein the total number of slots for repetition of the TBoMS transmission is obtained by multiplying the number of slots for the TBoMS, N, with the repetition number of the TBoMS, M, and
wherein the preconfigured number of slots is identified based on a maximum number of available slots for PUSCH repetition.
7. The method of claim 6 ,
wherein a slot is not counted in a number of N×M slots of the TBoMS transmission for a PUSCH repetition type A in case that count-based PUSCH repetition is configured, and
wherein the slot is unavailable for the TBoMS transmission.
8. The method of claim 5 ,
wherein the configuration information further includes at least one of information on a start symbol and a length of a symbol, or information on a PUSCH repetition type.
9. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller configured to:
control the transceiver to receive, from a base station, configuration information for a physical uplink shared channel (PUSCH) transmission including,
first information on a number of slots for transport block processing over multi-slots (TBoMS) and second information on a repetition number of the TBoMS, and
identify a total number of slots for repetition of TBoMS transmission based on the first information and the second information,
wherein the total number of slots is no larger than a preconfigured number of slots.
10. The terminal of claim 9 ,
wherein the total number of slots is obtained by multiplying the number of slots for the TBoMS, N, with the repetition number of the TBoMS, M, and
wherein the preconfigured number of slots is identified based on a maximum number of available slots for PUSCH repetition.
11. The terminal of claim 10 ,
wherein a slot is not counted in a number of N×M slots of the TBoMS transmission for a PUSCH repetition type A in case that count-based PUSCH repetition is configured, and
wherein the slot is unavailable for the TBoMS transmission.
12. The terminal of claim 9 ,
wherein the configuration information further includes at least one of information on a start symbol and a length of a symbol, or information on a PUSCH repetition type.
13. A base station in a wireless communication system, the base station comprising:
a transceiver; and
a controller configured to:
determine first information on a number of slots for transport block processing over multi-slots (TBoMS) and second information on a repetition number of the TBoMS, and
control the transceiver to transmit, to a terminal, configuration information for a physical uplink shared channel (PUSCH) transmission, the configuration information including the first information and the second information,
wherein the first information and the second information are associated with a total number of slots for repetition of TBoMS transmission, and
wherein the total number of slots is no larger than a preconfigured number of slots.
14. The base station of claim 13 ,
wherein the total number of slots for repetition of the TBoMS transmission is obtained by multiplying the number of slots for the TBoMS, N, with the repetition number of the TBoMS, M, and
wherein the preconfigured number of slots is identified based on a maximum number of available slots for PUSCH repetition.
15. The base station of claim 14 ,
wherein a slot is not counted in a number of N×M slots of the TBoMS transmission for a PUSCH repetition type A in case that count-based PUSCH repetition is configured, and
wherein the slot is unavailable for the TBoMS transmission.
16. The base station of claim 13 ,
wherein the configuration information further includes at least one of information on a start symbol and a length of a symbol, or information on a PUSCH repetition type.
