A method of a wireless communication device wherein the wireless communication device comprises: a radio transceiver; first (130, 310) and second (140, 330) autonomous radio access control units, wherein the first and second radio access control units are adapted to control operation of the wireless communication device in association with a first network node of a first radio access system and a second network node of a second radio access system, respectively; and a radio control unit (120, 320) adapted to manage time sharing of the radio transceiver by the first and second radio access control units; the method comprising, during use of the radio transceiver by the first radio access control unit: receiving, by the radio control unit, a first message from the second radio access control unit, the first message indicating a timing of an upcoming gap (203, 233, 263) in the use of the radio transceiver by the first radio access control unit, wherein the timing of the upcoming gap is autonomously established by the second radio access control unit; determining, by the radio control unit, whether a reception by the radio transceiver of an expected response to a planned uplink transmission by the first radio access control unit coincides with the timing of the upcoming gap; and if so sending, by the radio control unit, a second message to the first radio access control unit, the second message being configured to cause adaptation of the planned uplink transmission. a radio transceiver; first (130, 310) and second (140, 330) autonomous radio access control units, wherein the first and second radio access control units are adapted to control operation of the wireless communication device in association with a first network node of a first radio access system and a second network node of a second radio access system, respectively; and a radio control unit (120, 320) adapted to manage time sharing of the radio transceiver by the first and second radio access control units; the method comprising, during use of the radio transceiver by the first radio access control unit: receiving, by the radio control unit, a first message from the second radio access control unit, the first message indicating a timing of an upcoming gap (203, 233, 263) in the use of the radio transceiver by the first radio access control unit, wherein the timing of the upcoming gap is autonomously established by the second radio access control unit; determining, by the radio control unit, whether a reception by the radio transceiver of an expected response to a planned uplink transmission by the first radio access control unit coincides with the timing of the upcoming gap; and if so sending, by the radio control unit, a second message to the first radio access control unit, the second message being configured to cause adaptation of the planned uplink transmission. receiving, by the radio control unit, a first message from the second radio access control unit, the first message indicating a timing of an upcoming gap (203, 233, 263) in the use of the radio transceiver by the first radio access control unit, wherein the timing of the upcoming gap is autonomously established by the second radio access control unit; determining, by the radio control unit, whether a reception by the radio transceiver of an expected response to a planned uplink transmission by the first radio access control unit coincides with the timing of the upcoming gap; and if so sending, by the radio control unit, a second message to the first radio access control unit, the second message being configured to cause adaptation of the planned uplink transmission.
