Systems And Methods Of Sharing Channel Information Between Co-Located Radio Nodes

A second radio node capable of sharing channel information with a first radio node that is co-located with the second radio node, the second radio node comprising:

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the second radio node is operative to:
• obtain first channel information that characterizes a communication channel between a third radio node and the first radio node in a first frequency band;
• and
• use the first channel information for communication with the third node or a fourth radio node in a second frequency band.

A first radio node capable of sharing channel information with a second radio node that is co-located with the first radio node, the first radio node comprising:

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the device is operative to:
• obtain first channel information that characterizes a communication channel between a third radio node and the first radio node in a first frequency band;
• and
• send, to the second radio node, the first channel information so as to allow the second radio node to use the first channel information for communication with the third node or a fourth radio node in a second frequency band.

A method, performed by a network node, for sharing channel information between first and second radio nodes that are co-located, the method comprising the network node:

• receiving, from the first radio node, first channel information that characterizes a first communication channel between the first radio node and a third radio node in a first frequency band;
• determining second channel information that characterizes a second communication channel between the third node or a fourth radio node and the second radio node in the second frequency band based on the first channel information;
• and
• sending, to the second radio node, the second channel information so as to allow the second radio node to use the second channel information for communication with the third node or the fourth node in the second frequency band.
