Abstract

A method and a device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present disclosure, comprise the steps of: determining a physical uplink control channel (PUCCH) resource for transmitting the PUCCH; and transmitting the PUCCH through the PUCCH resource. The PUCCH resource is determined to be one of 16 PUCCH resources in a PUCCH resource set. The PUCCH resource set is a PUCCH resource set for a state in which there is no dedicated PUCCH resource configuration in a terminal. The number of physical resource blocks (PRBs) of the PUCCH resource can be determined on the basis of a received system information block (SIB).

Claims (44)

1 . A method comprising:

receiving, by a user equipment (UE), a system information block (SIB) including information related to a physical uplink control channel (PUCCH) resource;

determining the PUCCH resource related to one of PUCCH formats 0 and 1 based on the SIB; and

transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) information on a PUCCH through the PUCCH resource,

wherein the PUCCH resource is determined as one of sixteen PUCCH resources in a PUCCH resource set,

wherein the PUCCH resource set is for the UE not having dedicated PUCCH resource configuration, and

wherein, based on a frequency range for the PUCCH resource, a number of physical resource blocks (PRBs) of the PUCCH resource is provided in the SIB.

2 . The method of claim 1 , wherein the PUCCH is generated based on one PUCCH sequence of a length corresponding to the number of PRBs.

3 . The method of claim 1 , wherein invalid PUCCH resources among the sixteen PUCCH resources are not allocated.

4 . The method of claim 3 , wherein validity of the PUCCH resource is determined based on:

(i) the number of PRBs in the PUCCH resource;

(ii) a total number of RBs in a bandwidth; and

(iii) a set of initial cyclic shift (CS) indexes corresponding to the PUCCH resource set.

5 . A user equipment (UE) comprising:

at least one transceiver;

at least one processor; and

at least one memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform specific operations, the specific operations comprising:

receiving a system information block (SIB) including information related to a physical uplink control channel (PUCCH) resource;

determining the PUCCH resource related to one of PUCCH formats 0 and 1 based on the SIB; and

transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) information on a PUCCH through the PUCCH resource,

wherein the PUCCH resource is determined as one of sixteen PUCCH resources in a PUCCH resource set,

wherein the PUCCH resource set is for the UE not having dedicated PUCCH resource configuration, and

wherein, based on a frequency range for the PUCCH resource, a number of physical resource blocks (PRBs) of the PUCCH resource is provided in the SIB.

6 . The UE of claim 5 , wherein the PUCCH is generated based on one PUCCH sequence of a length corresponding to the number of PRBs.

7 . The UE of claim 5 , wherein invalid PUCCH resources among the sixteen PUCCH resources are not allocated.

8 . The UE of claim 7 , wherein validity of the PUCCH resource is determined based on:

(i) the number of PRBs in the PUCCH resource;

(ii) a total number of RBs in a bandwidth; and

(iii) a set of initial cyclic shift (CS) indexes corresponding to the PUCCH resource set.

9 . A base station (BS), the device comprising:

at least one processor; and

at least one computer memory operably connected to the at least one processor and configured to cause, when executed, the at least one processor to perform operations, the operations comprising:

transmitting, to a user equipment (UE), a system information block (SIB) including information related to a physical uplink control channel (PUCCH) resource;

receiving hybrid automatic repeat request acknowledgement (HARQ-ACK) information on a PUCCH through the PUCCH resource,

wherein the PUCCH resource related to one of PUCCH formats 0 and 1 is determined based on the SIB,

wherein the PUCCH resource is determined as one of sixteen PUCCH resources in a PUCCH resource set,

wherein the PUCCH resource set is for the UE not having dedicated PUCCH resource configuration, and

wherein, based on a frequency range for the PUCCH resource, a number of physical resource blocks (PRBs) of the PUCCH resource is provided in the SIB.

10 . The BS of claim 9 , wherein the PUCCH is generated based on one PUCCH sequence of a length corresponding to the number of PRBs.

11 . The BS of claim 9 , wherein invalid PUCCH resources among the sixteen PUCCH resources are not allocated.

12 . The BS of claim 11 , wherein validity of the PUCCH resource is determined based on:

(i) the number of PRBs in the PUCCH resource;

(ii) a total number of RBs in a bandwidth; and

(iii) a set of initial cyclic shift (CS) indexes corresponding to the PUCCH resource set.
