A method comprising: establishing , by a user equipment, UE, a communication tunnel with a first base station over a transmit, TX, chain, the TX chain being synchronized with a second base station, wherein the communication tunnel allows the UE to communicate with a first wireless network associated with the first base station via a second wireless network associated with the second base station, wherein the first wireless network is a non-public network, NPN, and the second wireless network is a mobile network operator, MNO, network; receiving, by the UE, a request from the first base station or the second base station requesting the UE to synchronize a first receive, RX, chain of the UE to the first base station to receive first traffic from the first wireless network and synchronize a second RX chain of the UE to the second base station to receive second traffic from the second wireless network; transmitting , via the TX chain of the UE, an uplink signal to the first wireless network associated with the first base station or the second wireless network associated with the second base station, the uplink signal including information indicative of the first RX chain of the UE being synchronized to the first base station to receive the first traffic from the first wireless network and the second RX chain of the UE being synchronized to the second base station to receive the second traffic from the second wireless network; and transmitting , by the UE, uplink traffic for the first wireless network and the second wireless network to the second base station via the TX chain of the UE. establishing , by a user equipment, UE, a communication tunnel with a first base station over a transmit, TX, chain, the TX chain being synchronized with a second base station, wherein the communication tunnel allows the UE to communicate with a first wireless network associated with the first base station via a second wireless network associated with the second base station, wherein the first wireless network is a non-public network, NPN, and the second wireless network is a mobile network operator, MNO, network; receiving, by the UE, a request from the first base station or the second base station requesting the UE to synchronize a first receive, RX, chain of the UE to the first base station to receive first traffic from the first wireless network and synchronize a second RX chain of the UE to the second base station to receive second traffic from the second wireless network; transmitting , via the TX chain of the UE, an uplink signal to the first wireless network associated with the first base station or the second wireless network associated with the second base station, the uplink signal including information indicative of the first RX chain of the UE being synchronized to the first base station to receive the first traffic from the first wireless network and the second RX chain of the UE being synchronized to the second base station to receive the second traffic from the second wireless network; and transmitting , by the UE, uplink traffic for the first wireless network and the second wireless network to the second base station via the TX chain of the UE. <EOS>
