Abstract
A method, system and apparatus are disclosed for power control between integrated access and backhaul (IAB) nodes. In one embodiment, a first node is provided. The first node includes processing circuitry configured to transmit a power control request to a parent, integrated access and backhaul, IAB, node where the power control request is configured to request an adjustment of a transmission power of the parent IAB node, receive a power control response from the parent IAB node, and perform at least one action associated with a second node based at least in part on the power control response.
Claims19
A first node comprising:
- processing circuitry configured to:
- transmit a power control request to a parent, integrated access and backhaul, IAB, node, the power control request configured to request an adjustment of a transmission power of the parent IAB node;
- receive a power control response from the parent IAB node;
- and
- perform at least one action associated with a second node based at least in part on the power control response, the at least one action comprising:
- at least temporarily pausing a scheduling for a wireless device that is outside of a distance threshold;
- and
- scheduling a wireless device that is within the distance threshold.
A method implemented by a first node, the method comprising:
- transmitting a power control request to a parent, integrated access and backhaul, IAB, node, the power control request configured to request an adjustment of a transmission power of the parent IAB node;
- receiving a power control response from the parent IAB node;
- and
- performing at least one action associated with a second node based at least in part on the power control response, the at least one action comprising:
- at least temporarily pausing a scheduling for a wireless device that is outside of a distance threshold;
- and
- scheduling a wireless device that is within the distance threshold.
A parent, integrated access and backhaul, IAB, node comprising:
- processing circuitry configured to:
- receive a power control request from a first node, the power control request is configured to request an adjustment of a transmission power of the parent IAB node;
- and
- cause transmission of a power control response to the first node, the power control response being a negative acknowledgment that indicates the transmission power of the parent IAB node is not being adjusted.
