1. A method, performed by a first network node, for managing channel access for a Wireless Device (WD) which supports one or more Radio Access Technologies (RATs), the method comprising:
receiving, from the WD, a radio channel access request comprising information regarding a number of requirements on the channel access;
measuring the channel status for all channels for all RATs within the geographical area served by the first network node; and
storing the measured channel statuses;
sending, to a second network node, the channel status for all channels for all RATs within the geographical area served by the first network node; and
receiving, from a second network node, the channel status for all channels for all RATs within the geographical area served by the second network node;
determining a channel access schedule based on the received information and channel statuses that are received and/or stored for the channels and RATs available within respective geographical areas served by the first network node and the second network node, the channel access schedule comprising information about a radio channel assigned to the WD; and
sending the channel access schedule to the WD.
