Electronic device, communication method and storage medium

An electronic device for a node in an integrated access and backhaul (IAB) system, the node being referred to as the first node, there being an access link between the first node and user equipment, there being a backhaul link between the first node and a second node of the TAB system, where the second node is a parent node of the first node in network topology of the TAB system, characterized in the electronic device comprising:

• a processing circuitry configured to:
• receive, from the user equipment, an interference measurement of signal interference from a third node;
• in a case where the second node makes a determination to switch the access link used by the user equipment based at least in part on the interference measurement exceeding a predetermined threshold, receive from the second node an instruction to disconnect the access link between the first node and the user equipment, and
• disconnect the access link between the first node and the user equipment.

An electronic device for a node in an integrated access and backhaul (IAB) system, the node being referred to as a second node, there being a backhaul link between a first node and the second node of the IAB system, wherein the first node is a child node of the second node in network topology of the IAB system, and there is an access link between the user equipment and the first node, characterized in the electronic device comprising

• a processing circuitry configured to:
• make a determination to switch the access link used by the user equipment based at least in part on an interference measurement of signal interference from a third node by the user equipment exceeding a predetermined threshold;
• and
• in response to the determination, establish a direct access link between the second node and the user equipment and instruct the first node to disconnect the access link between the first node and the user equipment.

An electronic device for a node in an integrated access and backhaul (IAB) system, the node being referred to as a second node, there being a backhaul link between the second node and a first node of the IAB system, wherein the second node is a parent node of the first node in network topology of the IAB system, and there is an access link between the user equipment and the first node, wherein the electronic device comprises

• a processing circuitry configured to:
• acquire, with a reference signal transmitted between the second node and the user equipment, integrated channel state information of a downlink baseband integrated channel through the backhaul link, the first node, and the access link, wherein the first node operates in Amplify and Forward (AF) mode;
• and
• based on the acquired integrated channel state information, calculate a digital precoding matrix for downlink transmission of the user equipment.
