Abstract
Official abstract text for this publication.
In one of the example aspects, the technology disclosed herein concerns an Integrated Access and Backhaul (IAB) node that communicates over a radio interface. The IAB node includes mobile-termination circuitry, distributed unit circuitry, and processor circuitry. The mobile-termination circuitry is configured to transmit over the radio interface with a parent node. The distributed unit circuitry is configured to transmit over the radio interface with a child node. The processor circuitry is configured to manage the transmission power utilized by the IAB node by taking into consideration both transmission by the mobile-termination circuitry and transmission by the distributed unit circuitry. Other example aspects of the technology disclosed herein concern the transmission power reporting by such IAB node, transmission power prioritization by such IAB node, transmission power governance for the distributed unit circuitry for such IAB node, and a method of operating such IAB node(s).
First claim
Opening claim text (preview).
The invention claimed is: 1. An Integrated Access and Backhaul (IAB) node that communicates over a radio interface, the IAB node comprising: mobile-termination circuitry configured to transmit over the radio interface with a parent node; distribution circuitry configured to transmit over the radio interface with a child node; and processor circuitry configured to manage transmission power utilized by the IAB node by taking into consideration both the transmission by the mobile-termination circuitry and the transmission by the distribution circuitry, wherein the processor circuitry is further configured to determine the transmission power utilized by the IAB node by determining each of: power utilization by the mobile-termination circuitry for transmission on a Physical Uplink Shared Channel (PUSCH); power utilization by the mobile-termination circuitry for transmission on a Physical Uplink Control Channel (PUCCH); power utilization by the distribution circuitry for transmission on a Physical Downlink Shared Channel (PDSCH); and power utilization by the distribution circuitry for transmission on a Physical Downlink Control Channel (PDCCH). 2. The IAB node of claim 1 , wherein the processor circuitry is further configured to generate a report of the transmission power utilized by the IAB node, and the mobile-termination circuitry is further configured to transmit the report of transmission power utilized by the IAB node to the parent node.
