The disclosure relates to a method and wireless device configured for communication in a wireless communication network, the method comprising the steps of obtaining a first transmission time interval, TTI, used for transmission timing of a first signal, obtaining a second TTI, used for transmission timing of a second signal, obtaining a maximum received time difference, MRTD, parameter, and operating the first signal between a wireless device and a first cell using the MRTD parameter and a first carrier, and the second signal between the wireless device and a second cell using the MRTD parameter and a second carrier, the second carrier being different from the first carrier, wherein the MRTD parameter is obtained by determining the MRTD parameter based on the first and the second TTI. The disclosure further relates to a network node and a method thereof.
