Methods providing resource coordination information between ran nodes for sidelink communications and related network nodes

A master radio access network, RAN, node for a wireless communication network, the node comprising:

• a processor;
• and
• memory coupled with the processor, wherein the memory includes instructions that when executed by the processor causes the master RAN node to,
• transmit from the master RAN node to a secondary RAN node a secondary RAN node addition or modification request message to request preparation or modification of resources for dual connectivity communication for a wireless terminal,
• wherein resource coordination information is included as an information element of the secondary RAN node addition or modification request message and defines at least one communication resource that is available for a wireless terminal to use for sidelink communication.

A secondary radio access network, RAN, node for a wireless communication network, the node comprising:

• a processor;
• and
• memory coupled with the processor, wherein the memory includes instructions that when executed by the processor causes the secondary RAN node to,
• receive, from a master RAN node, a secondary RAN node addition or modification request message to request preparation or modification of resources for dual connectivity communication for a wireless terminal,
• wherein resource coordination information is included as an information element of the secondary RAN node addition or modification request message and defines at least one communication resource that is available for a wireless terminal to use for sidelink communication.
