1. A method performed by a wireless device in a wireless communication system, the method comprising,
establishing a connection with a cell;
receiving configuration of multiple bandwidth parts on the cell,
wherein the multiple BWPs includes a first active bandwidth part for uplink transmission and a second active bandwidth part for device-to-device direct communication;
detecting a triggering condition for switching from the first active bandwidth part for uplink transmission to a specific bandwidth part for uplink transmission,
wherein the specific bandwidth part for uplink transmission cannot be simultaneously active with the second active bandwidth part for device-to-device direct communication;
based on that 1) a first priority value for uplink transmission is higher than a first threshold value for uplink transmission and a second priority value for device-to-device direct communication, and 2) the second priority value for device-to-device direct communication is lower than or equal to a second threshold for device-to-device direct communication:
determining not to switch from the first active bandwidth part for uplink transmission to the specific bandwidth part for uplink transmission; and
skipping the switching from the first active bandwidth part for uplink transmission to the specific bandwidth part for uplink transmission;
based on that 1) a first priority value for uplink transmission is lower than or equal to the first threshold value for uplink transmission and the second priority value for device-to-device direct communication, or 2) the second priority value for device-to-device direct communication is higher than the second threshold for device-to-device direct communication:
determining to switch from the first active bandwidth part for uplink transmission to the specific bandwidth part for uplink transmission; and
performing the switching from the first active bandwidth part for uplink transmission to the specific bandwidth part for uplink transmission.
