Electronic device, method and storage medium for wireless communication system

An electronic device for a second IAB node in an integrated access and backhaul (IAB) communication system, wherein the IAB communication system comprises an IAB donor and at least a first IAB node and the second IAB node, operating frequency bands of the IAB donor and the IAB nodes at least partially overlap, and wherein the electronic device comprises a processing circuit, the processing circuit being configured to:

• send first information of the second IAB node to a spectrum management device,
• wherein the first information comprises a location and radio RX/TX status of the second IAB node, and the radio RX/TX status comprises one or more of an antenna array configuration, a beam configuration, a transmit power, or a current reception performance of the second IAB node;
• and
• receive control information from the spectrum management device,
• wherein the control information comprises at least one of the following:
• path information, for instructing the second IAB node to avoid approaching the first IAB node;
• or
• adjustment information for the radio RX/TX status, for instructing of adjusting beam direction of the second IAB node or reducing transmit power of the second IAB node,
• wherein, based on the first information, a first power-limited area of the first IAB node for the second IAB node, a first power-limited area of the first IAB node for the second IAB node is calculated,
• wherein the first power-limited area defines a three-dimensional space surrounding the first IAB node, and the second IAB node will cause interference to the first IAB node when entering the first power-limited area with its radio RX/TX status,
• wherein the second IAB node is instructed according to at least one of:
• the path information instructs the second IAB node to avoid entering the first power-limited area, or
• the adjustment information for the radio RX/TX status instructs the second IAB node to adjust the beam direction or reduce the transmit power when entering the first power-limited area.
