Method for transmitting and receiving physical uplink control channel in wireless communication system, and device for same
According to one embodiment of the present application, a method for transmitting a physical uplink control channel (PUCCH) by a terminal in a wireless communication system comprises a step of receiving setting information associated with a PUCCH, and a step of transmitting the PUCCH on the basis of the setting information. The PUCCH is transmitted from a specific PUCCH resource selected from among overlapped PUCCH resources. The specific PUCCH resource is characterized by being associated with beam failure recovery (BFR).
1. A method of transmitting, by a user equipment, a Scheduling Request (SR) in a wireless communication system, the method comprising:
receiving configuration information related to the SR; and
transmitting the SR on a valid Physical Uplink Control Channel (PUCCH) resource among PUCCH resources based on the configuration information,
wherein the valid PUCCH resource is based on a PUCCH resource on a bandwidth part (BWP) which is active at a time of SR transmission occasion,
wherein, based on the valid PUCCH resource being based on overlapping valid PUCCH resources:
a pre-defined PUCCH resource among the overlapping valid PUCCH resources is determined as valid,
the SR is transmitted on the pre-defined PUCCH resource, and
the pre-defined PUCCH resource is based on a PUCCH resource configured for a beam failure recovery (BFR) of a Secondary Cell (SCell).
2. The method of claim 1 ,
wherein the pre-defined PUCCH resource is based on a PUCCH format 0 or a PUCCH format 1.
3. The method of claim 1 , further comprising receiving downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) related to the SR.
4. The method of claim 3 , further comprising transmitting the PUSCH based on the DCI.
5. The method of claim 4 ,
wherein the PUSCH is related to a medium access control-control element (MAC-CE) including information related to the BFR.
6. The method of claim 5 ,
wherein the MAC-CE includes information for at least one of 1) an index related to at least one SCell in which a beam failure is detected or 2) a new beam.
7. The method of claim 6 ,
wherein the information for the new beam includes i) whether the new beam is present and ii) an ID of a Reference Signal (RS) related to the new beam.
8. The method of claim 1 , wherein the transmission of the SR is performed based on i) a timer related to the
transmission of the SR and ii) a maximum transmission number of the SR.
9. A user equipment configured to transmit a Scheduling Request (SR) in a wireless communication system, the user equipment comprising:
one or more transceivers;
one or more processors controlling the one or more transceivers; and
one or more memories operatively coupled to the one or more processors and storing instructions that, based on being executed by the one or more processors, perform operations comprising:
receiving configuration information related to the SR; and
transmitting the SR on a valid Physical Uplink Control Channel (PUCCH) resource among PUCCH resources based on the configuration information,
wherein the valid PUCCH resource is based on a PUCCH resource on a bandwidth part (BWP) which is active at a time of SR transmission occasion,
wherein, based on the valid PUCCH resource being based on overlapping valid PUCCH resources:
a pre-defined PUCCH resource among the overlapping valid PUCCH resources is determined as valid,
the SR is transmitted on the pre-defined PUCCH resource, and
the pre-defined PUCCH resource is based on a PUCCH resource configured for a beam failure recovery (BFR) of a Secondary Cell (SCell).
10. A base station configured to receive a Scheduling Request (SR) in a wireless communication system, the base station comprising:
one or more transceivers;
one or more processors controlling the one or more transceivers; and
one or more memories operatively coupled to the one or more processors and storing instructions that, based on being executed by the one or more processors, perform operations comprising:
transmitting configuration information related to the SR, and
receiving the SR on a valid Physical Uplink Control Channel (PUCCH) resource among PUCCH resources based on the configuration information,
wherein the valid PUCCH resource is based on a PUCCH resource on a bandwidth part (BWP) which is active at a time of SR transmission occasion,
wherein, based on the valid PUCCH resource being based on overlapping valid PUCCH resources:
a pre-defined PUCCH resource among the overlapping valid PUCCH resources is determined as valid,
the SR is received on the pre-defined PUCCH resource, and
the pre-defined PUCCH resource is based on a PUCCH resource configured for a beam failure recovery (BFR) of a Secondary Cell (SCell).
