Method and apparatus for reallocating pucch resource according to change of sps operation in wireless communication system

A wireless device in a wireless communication system, the wireless device comprising:

• a memory;
• a transceiver;
• and
• a processor, operably coupled to the memory and the transceiver, and configured to:
• control the transceiver to receive, from a network, (1) a first pre-allocated resource configuration with a first period and (2) a second pre-allocated resource configuration with a second period, wherein the first pre-allocated resource configuration includes information on a first Physical Uplink Control Channel (PUCCH) resource, and wherein the second pre-allocated resource configuration includes information on a second PUCCH resource;
• control the transceiver to receive, from the network, a first control information to activate a resource grant for the first pre-allocated resource configuration;
• control the transceiver to transmit, to at least one other wireless device, a first sidelink (SL) data based on the resource grant for the first pre-allocated resource configuration with the first period;
• control the transceiver to transmit, to the network, a first uplink control information based on the first PUCCH resource with a first timing;
• control the transceiver to receive, from the network, a second control information to activate a resource grant for the second pre-allocated resource configuration;
• control the transceiver to transmit, to at least one other wireless device, a second SL data based on the resource grant for the second pre-allocated resource configuration with the second period;
• and
• control the transceiver to transmit, to the network, a second uplink control information based on the second PUCCH resource with a second timing.

A method performed by a base station in a wireless communication system, the method comprising,

• transmitting, to a wireless device, (1) a first pre-allocated resource configuration with a first period and (2) a second pre-allocated resource configuration with a second period, wherein the first pre-allocated resource configuration includes information on a first Physical Uplink Control Channel (PUCCH) resource, and wherein the second pre-allocated resource configuration includes information on a second PUCCH resource;
• transmitting, to the wireless device, a first control information to activate a resource grant for the first pre-allocated resource configuration;
• receiving, from the wireless device, a first uplink control information based on the first PUCCH resource with a first timing, wherein the first uplink control information is related to a first sidelink (SL) data which is transmitted from the wireless device to at least one other wireless device based on the resource grant for the first pre-allocated resource configuration with the first period;
• transmitting, to the wireless device, a second control information to activate a resource grant for the second pre-allocated resource configuration;
• and
• receiving, from the wireless device, a second uplink control information based on the second PUCCH resource with a second timing, wherein the second uplink control information is related to a second SL data which is transmitted from the wireless device to at least one other wireless device based on the resource grant for the second pre-allocated resource configuration with the second period.
