Radio communication node
A wireless communication node sets a downlink target value of a received power of a downlink from an upper node based on a received power of an uplink from a lower node, and transmits, to the upper node, power control information based on the downlink target value.
1 . A radio communication node comprising:
a Mobile Termination, which is a function for connecting to an IAB (Integrated Access and Backhaul) donor node;
a Distributed Unit, which is a function for connecting to an IAB child node;
a processor that configures a target value of a downlink transmission power from the IAB donor node; and
a transmitter that indicates, to the IAB donor node, power control information related to the target value using a specific index of LCID (Logical Channel ID) in a MAC-CE (Medium Access Control-Control Element).
2 . A radio communication method performed by a radio communication node including a Mobile Termination, which is a function for connecting to an IAB (Integrated Access and Backhaul) donor node, and a Distributed Unit, which is a function for connecting to an IAB child node, comprising:
configuring a target value of a downlink transmission power from the IAB donor node; and
indicating, to the IAB donor node, power control information related to the target value using a specific index of LCID (Logical Channel ID) in a MAC-CE (Medium Access Control-Control Element).
