Abstract

The disclosure relates to a communication technique for convergence between an IoT technology and a 5G system for supporting higher data transmission rate beyond a 4G system, and a system thereof. The disclosure may be applied to intelligence services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety related services, etc.), based on a 5G communication system and an IoT related technology. The disclosure provides a method and apparatus for transmitting uplink control information by a terminal.

First claim

What is claimed is:

1. A method performed by a terminal in a communication system, the method comprising:
receiving, from a base station, configuration information on a physical uplink control channel (PUCCH), the configuration information including a sub-slot configuration for the PUCCH;
receiving, from the base station, downlink control information (DCI) for scheduling downlink data, the DCI including a feedback timing indicator and a PUCCH resource indicator (PRI);
receiving, from the base station, the downlink data on a physical downlink shared channel (PDSCH) based on the DCI;
identifying a sub-slot for the PUCCH and a PUCCH resource based on the sub-slot configuration for the PUCCH, the feedback timing indicator, and the PRI; and
transmitting, to the base station, HARQ-ACK information for the downlink data on the identified PUCCH resource in the sub-slot for the PUCCH,
wherein the sub-slot configuration for the PUCCH includes information on a length of the sub-slot for the PUCCH,
wherein the information on the length of the sub-slot for the PUCCH indicates one of 2 or 7 symbols in case that a normal cyclic prefix is applied, and
wherein the information on the length of the sub-slot for the PUCCH indicates one of 2 or 6 symbols in case that an extended cyclic prefix is applied.

2. The method of claim 1 , wherein the sub-slot for the PUCCH is identified based on a number of sub-slots indicated by the feedback timing indicator.

3. The method of claim 1 , wherein the PRI indicates the PUCCH resource in the sub-slot for the PUCCH indicated by the feedback timing indicator.

4. The method of claim 1 , wherein a starting symbol index for the PUCCH associated with the PRI is identified based on a first orthogonal frequency-division multiplexing (OFDM) symbol of the sub-slot for the PUCCH.

5. A method performed by a base station in a communication system, the method comprising:
transmitting, to a terminal, configuration information on a physical uplink control channel (PUCCH), the configuration information including a sub-slot configuration for the PUCCH;
transmitting, to the terminal, downlink control information (DCI) for scheduling downlink data, the DCI including a feedback timing indicator and a PUCCH resource indicator (PRI);
transmitting, to the terminal, the downlink data on a physical downlink shared channel (PDSCH); and
receiving, from the terminal, HARQ-ACK information corresponding to the downlink data on a PUCCH resource in a sub-slot for the PUCCH,
wherein the sub-slot for the PUCCH and the PUCCH resource depend on the sub-slot configuration for the PUCCH, the feedback timing indicator, and the PRI,
wherein the sub-slot configuration for the PUCCH includes information on a length of the sub-slot for the PUCCH,
wherein the information on the length of the sub-slot for the PUCCH indicates one of 2 or 7 symbols in case that a normal cyclic prefix is applied, and
wherein the information on the length of the sub-slot for the PUCCH indicates one of 2 or 6 symbols in case that an extended cyclic prefix is applied.

6. The method of claim 5 , wherein the sub-slot for the PUCCH corresponds to a number of sub-slots indicated by the feedback timing indicator.

7. The method of claim 5 , wherein the PRI indicates the PUCCH resource in the sub-slot for the PUCCH indicated by the feedback timing indicator.

8. The method of claim 5 , wherein a starting symbol index for the PUCCH associated with the PRI is based on a first orthogonal frequency-division multiplexing (OFDM) symbol of the sub-slot for the PUCCH.

9. A terminal in a communication system, the terminal comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
receive, from a base station, configuration information on a physical uplink control channel (PUCCH), the configuration information including a sub-slot configuration for the PUCCH,
receive, from the base station, downlink control information (DCI) for scheduling downlink data, the DCI including a feedback timing indicator and a PUCCH resource indicator (PRI),
receive, from the base station, the downlink data on a physical downlink shared channel (PDSCH) based on the DCI,
identify a sub-slot for the PUCCH and a PUCCH resource based on the sub-slot configuration for the PUCCH, the feedback timing indicator, and the PRI, and
transmit, to the base station, HARQ-ACK information for the downlink data on the identified PUCCH resource in the sub-slot for the PUCCH,
wherein the sub-slot configuration for the PUCCH includes information on a length of the sub-slot for the PUCCH,
wherein the information on the length of the sub-slot for the PUCCH indicates one of 2 or 7 symbols in case that a normal cyclic prefix is applied, and
wherein the information on the length of the sub-slot for the PUCCH indicates one of 2 or 6 symbols in case that an extended cyclic prefix is applied.

10. The terminal of claim 9 , wherein the sub-slot for the PUCCH is identified based on a number of sub-slots indicated by the feedback timing indicator.

11. The terminal of claim 9 , wherein the PRI indicates the PUCCH resource in the sub-slot for the PUCCH indicated by the feedback timing indicator.

12. The terminal of claim 9 , wherein a starting symbol index for the PUCCH associated with the PRI is identified based on a first orthogonal frequency-division multiplexing (OFDM) symbol of the sub-slot for the PUCCH.

13. A base station in a communication system, the base station comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
transmit, to a terminal, configuration information on a physical uplink control channel (PUCCH), the configuration information including a sub-slot configuration for the PUCCH,
