Radio Network Node, Wireless Device and Methods Performed Therein for Handling Communication in a Wireless Communication Network

A method performed by a wireless device for handling communication for the wireless device in a second wireless communication network, wherein the second wireless communication network coexists with a first wireless communication network on a same bandwidth in frequency, wherein the first wireless communication network applies a first shift in frequency in uplink transmissions, wherein the method comprises:

• receiving from a radio network node, an indication indicating application of a second shift in frequency to uplink transmissions in case the second wireless communication network uses Frequency Division Duplex, FDD;
• and
• applying the second shift in frequency to uplink transmissions, wherein the second shift defines a shift in frequency to a subcarrier relative to a subcarrier grid of the second wireless communication network or a shift in frequency to the subcarrier grid of the second wireless communication network.

A method performed by a radio network node for enabling communication for a wireless device in a second wireless communication network, wherein the second wireless communication network coexists with a first wireless communication network on a same bandwidth in frequency, wherein the first wireless communication network applies a first shift in frequency for uplink transmissions, wherein the method comprises:

• transmitting to the wireless device, an indication indicating application of a second shift in frequency to uplink transmissions in case the second wireless communication network uses frequency division duplex, FDD, wherein the second shift defines a shift in frequency to a subcarrier relative to a subcarrier grid of the second wireless communication network, or a shift in frequency to the subcarrier grid of the second wireless communication network.
