1. A wireless device configured to communicate with a network node, the wireless device comprising processing circuitry configured to:
determine a quantity of timing management groups (TMGs) associated with a first signal in a first cell and a second signal in a second cell;
determine at least one maximum operational timing difference (MOTD) parameter based at least in part on the quantity of TMGs, the at least one MOTD parameter corresponding to a maximum time difference in communication between the first signal and the second signal; and
communicate with the first cell using the first signal and the second cell using the second signal based at least in part on the at least one MOTD parameter, wherein the quantity of TMGs is determined to be one TMG where the first cell and the second cell being part of the one TMG, and
wherein the quantity of TMGs is determined to be greater than two TMGs where the at least one MOTD parameter corresponding to a plurality of MOTD parameters, and each TMG operating according to a respective one of the plurality of MOTD parameters.
