INTEGRATED ACCESS AND BACKHAUL (IAB) DOWNLINK POWER CONTROL

Abstract:

To configure an IAB node for DL power control, the processing circuitry of the node is to decode at a DU function of the IAB node, an UL reference signal received via a communication channel from an MT function of a second IAB node. A path loss associated with the communication channel is determined, based on at least one measurement of the UL reference signal. DL transmission power is determined using the path loss. Data is encoded for a transmission to the MT function of the second IAB node using the DL transmission power, the transmission further using a DL BWP associated with the channel.
