Wireless device and a network node for a wireless communication system and methods thereof

A method for a network node for communication in a wireless communication network, the method comprising:

• obtaining a first transmission time interval used for transmission timing of a first signal (S1);
• obtaining a second transmission time interval used for transmission timing of a second signal (S2);
• obtaining a maximum received time difference, MRTD, parameter;
• and
• operating:
• the first signal (S1) between a wireless device and a first cell using the MRTD parameter and a first carrier (F1), and
• the second signal (S2) between the wireless device and a second cell using the MRTD parameter and a second carrier (F2) different from the first carrier (F1), wherein the MRTD parameter is obtained by determining the MRTD parameter based on the first transmission time interval and the second transmission time interval.
