Abstract

The disclosure relates to a 5 th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4 th generation (4G) communication system such as long term evolution (LTE). An operating method of a terminal in a wireless communication system is provided. The operating method includes receiving, from a base station, first configuration information regarding transport block (TB) processing over multi-slot (TBoMS) or a joint channel configuration, allocating a physical uplink shared channel (PUSCH) transmission resource based on the first configuration information, receiving, from the base station, second configuration information regarding a cancellation indication (CI) or a dynamic slot-format indication (SFI), determining whether to transmit the PUSCH transmission resource, based on the second configuration information, configuring a transmit power and a phase regarding TBoMS PUSCH transmission, PUSCH transmission, or PUSCH repetitive transmission, based on the first configuration information, and performing at least one of the TBoMS PUSCH transmission, the PUSCH transmission, or the PUSCH repetitive transmission, based on the PUSCH transmission resource.

First claim

What is claimed is:

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, configuration information associated with a physical uplink shared channel (PUSCH) repetition;
transmitting, to the base station, a first PUSCH for the PUSCH repetition based on the configuration information associated with the PUSCH repetition;
identifying that an event occurs which causes a phase continuity for the PUSCH repetition not to be maintained, wherein the event is associated with a reception of downlink control information (DCI) including a cancellation indication (CI) or a dynamic slot-format indication (SFI);
identifying whether to restart a bundling associated with the PUSCH repetition; and
transmitting, to the base station, a second PUSCH for the PUSCH repetition after the event, based on the identification whether to restart the bundling associated with the PUSCH repetition.

2. The method of claim 1 ,
wherein the PUSCH repetition is stopped based on the event,
wherein the event is associated with an overlap with a higher priority PUSCH transmission,
wherein the bundling associated with the PUSCH repetition is restarted from a first symbol after the event, and
wherein whether to restart the bundling associated with the PUSCH repetition is identified based on a capability of the UE.

3. The method of claim 1 , wherein the configuration information is for a transport block (TB) processing over multi-slot (TBoMS), and the configuration information is received through a higher layer signaling.

4. The method of claim 1 , wherein the configuration information comprises at least one of a position of a start symbol, a length of a symbol, a number of multiple slots, a time domain resource allocation type, or a bundling size for joint channel estimation.

5. A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a user equipment (UE), configuration information associated with a physical uplink shared channel (PUSCH) repetition;
receiving, from the UE, a first PUSCH for the PUSCH repetition based on the configuration information associated with the PUSCH repetition;
identifying that an event occurs which causes a phase continuity for the PUSCH repetition not to be maintained, wherein the event is associated with a transmission of downlink control information (DCI) including a cancellation indication (CI) or a dynamic slot-format indication (SFI); and
receiving, from the UE, a second PUSCH for the PUSCH repetition after the event, wherein a bundling associated with the PUSCH repetition is restarted after the event.

6. The method of claim 5 ,
wherein the PUSCH repetition is stopped based on the event,
wherein the event is associated with an overlap with a higher priority PUSCH transmission,
wherein the bundling associated with the PUSCH repetition is restarted from a first symbol after the event, and
wherein the bundling associated with the PUSCH repetition is restarted based on a capability of the UE.

7. The method of claim 5 ,
wherein the configuration information is for a transport block (TB) processing over multi-slot (TBoMS) and the configuration information is transmitted through a higher layer signaling, and
wherein the configuration information comprises at least one of a position of a start symbol, a length of a symbol, a number of multiple slots, a time domain resource allocation type, or a bundling size for joint channel estimation.

8. A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
receive, from a base station, configuration information associated with a physical uplink shared channel (PUSCH) repetition,
transmit, to the base station, a first PUSCH for the PUSCH repetition based on the configuration information associated with the PUSCH repetition,
identify that an event occurs which causes a phase continuity for the PUSCH repetition not to be maintained, wherein the event is associated with a reception of downlink control information, DCI, including a cancellation indication (CI) or a dynamic slot-format indication (SFI),
identify whether to restart a bundling associated with the PUSCH repetition, and
transmit, to the base station, a second PUSCH for the PUSCH repetition after the event, based on the identification whether to restart the bundling associated with the PUSCH repetition.

9. The UE of claim 8 ,
wherein the PUSCH repetition is stopped based on the event,
wherein the event is associated with an overlap with a higher priority PUSCH transmission,
wherein the bundling associated with the PUSCH repetition is restarted from a first symbol after the event, and
wherein whether to restart the bundling associated with the PUSCH repetition is identified based on a capability of the UE.

10. The UE of claim 8 , wherein the configuration information is for a transport block (TB) processing over multi-slot (TBoMS), and the configuration information is received through a higher layer signaling.

11. The UE of claim 8 , wherein the configuration information comprises at least one of a position of a start symbol, a length of a symbol, a number of multiple slots, a time domain resource allocation type, or a bundling size for joint channel estimation.

12. A base station in a wireless communication system, the base station comprising:
