Method and device for transmitting or receiving uplink or downlink in wireless communication system

1 . A method comprising:

transmitting, by a user equipment (UE) to a base station, capability information including first information related to whether the UE supports an activation of only a single panel among a plurality of panels in a single time unit or activation of the plurality of panels in a single time unit;

receiving, by the UE from the base station, second information related to at least one transmission occasion (TO) based on the capability information; and

based on the second information, performing, by the UE, uplink transmission or downlink reception in the at least one TO,

wherein the capability information includes information on a time it takes to activate a single panel, and a minimum time offset between a time when downlink control information (DCI) including the second information is received and an initial TO at which the uplink transmission or the downlink reception is performed, and

wherein based on the UE supporting an activation of the plurality of panels in a single time unit and only a first panel of the plurality of panels being activated:

i) a first time offset between a time when the DCI including the second information is received and a time when the downlink reception scheduled by the DCI is performed and ii) a second time offset between a time when the downlink reception is performed and a TO at which an uplink transmission related to the downlink reception is first performed are received from the base station, and

a sum of the first time offset and the second time offset has a value equal to or greater than at least one of the time it takes to activate the single panel or the minimum time offset.

2 . The method of claim 1 , wherein:

the capability information includes information on at least one activated panel among the plurality of panels.

3 . The method of claim 1 , wherein:

based on the UE supporting an activation of only a single panel among the plurality of panels in a single time unit, the second information includes information for configuring a gap symbol between a first TO among the at least one TO and a second TO adjacent to the first TO,

the first TO is a TO in which the uplink transmission or the downlink reception is performed by an activated first panel among the plurality of panels, and

the second TO is a TO in which the uplink transmission or the downlink reception is performed by an activated second panel among the plurality of panels.

4 . The method of claim 1 , wherein:

based on the UE supporting an activation of the plurality of panels in a unit of time and all of the plurality of panels being activated, the uplink transmission or the downlink reception is performed in the at least one TO to which a gap symbol is not applied.

5 . The method of claim 2 , wherein:

the uplink transmission includes at least one of transmission of a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH) including an acknowledgment (ACK)/negative acknowledgment (NACK) for a physical downlink shared channel (PDSCH), and

the downlink reception includes reception of the PDSCH.

6 . The method of claim 1 , wherein:

based on the UE supporting an activation of the plurality of panels in a single time unit and only a first panel of the plurality of panels being activated, during the sum of the first time offset and the second time offset after the DCI is received, the plurality of panels are all activated by the UE.

7 . The method of claim 1 , wherein:

the at least one TO includes a first TO and a second TO adjacent to the first TO, and

based on the uplink transmission or the downlink reception being performed through a first panel or a first beam in the first TO and the uplink transmission or the downlink reception being performed through a second panel or a second beam in the second TO, the second information includes information for configuring a gap symbol between the first TO and the second TO.

8 . A user equipment (UE) comprising:

at least one transceiver; and

at least one processor connected to the at least one transceiver,

wherein the at least one processor is configured to:

transmit, to a base station through the at least one transceiver, capability information including first information related to whether the UE supports an activation of only a single panel among a plurality of panels in a single time unit or activation of the plurality of panels in a single time unit;

receive, from the base station through the at least one transceiver, second information related to at least one transmission occasion (TO) based on the capability information; and

based on the second information, perform uplink transmission or downlink reception in the at least one TO,

wherein the capability information includes information on a time it takes to activate a single panel, and a minimum time offset between a time when downlink control information (DCI) including the second information is received and an initial TO at which the uplink transmission or the downlink reception is performed, and

wherein based on the UE supporting an activation of the plurality of panels in a single time unit and only a first panel of the plurality of panels being activated:

i) a first time offset between a time when the DCI including the second information is received and a time when the downlink reception scheduled by the DCI is performed and ii) a second time offset between a time when the downlink reception is performed and a TO at which the uplink transmission related to the downlink reception is first performed are received from the base station, and

a sum of the first time offset and the second time offset has a value equal to or greater than at least one of the time it takes to activate the single panel or the minimum time offset.

9 . A base station comprising:

at least one transceiver; and

at least one processor connected to the at least one transceiver,

wherein the at least one processor is configured to:

receive, from a user equipment (UE) through the at least one transceiver, capability information including first information related to whether the UE supports an activation of only a single panel among a plurality of panels in a single time unit or activation of the plurality of panels in a single time unit;

transmit, to the UE through the at least one transceiver, second information related to at least one transmission occasion (TO) based on the capability information; and

based on the second information, perform uplink reception or downlink transmission in the at least one TO,

wherein the capability information includes information on a time it takes to activate a single panel, and a minimum time offset between a time when downlink control information (DCI) including the second information is transmitted and an initial TO at which the uplink reception or the downlink transmission is performed, and

wherein based on the UE supporting an activation of the plurality of panels in a single time unit and only a first panel of the plurality of panels being activated:

i) a first time offset between a time when the DCI including the second information is transmitted and a time when the downlink transmission scheduled by the DCI is performed and ii) a second time offset between a time when the downlink transmission is performed and a TO at which the uplink reception related to the downlink transmission is first performed are transmitted to the UE, and

a sum of the first time offset and the second time offset has a value equal to or greater than at least one of the time it takes to activate the single panel or the minimum time offset.
