US 12,713,447 B2 · DCI enhancements for soft resource availability indication

Abstract

An apparatus for an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the IAB node for resource availability indication in an IAB network, configuration signaling received from a CU function of an IAB donor node is decoded at a DU function of the IAB node. The configuration signaling configures a frequency-domain hard, soft, and not available (H/S/NA) resource application for a plurality of resource types. DCI received from a P-DU function of a parent IAB node is decoded at an MT function of the IAB node. The DCI includes an availability indicator for at least one soft resource region associated with the frequency-domain H/S/NA resource application. A downlink transmission by the DU function of the IAB node to a C-MIT function of a child IAB node is configured using the at least one soft resource region based on the availability indicator.

Dependent claims

An apparatus for an Integrated Access and Backhaul (IAB) node, the apparatus comprising:

processing circuitry, wherein to configure the IAB node for resource availability indication in an IAB network, the processing circuitry is to:
decode at a distributed unit (DU) function of the IAB node, configuration signaling received from a central unit (CU) function of an IAB donor node, and the configuration signaling to configure a frequency-domain hard, soft, and not available (H/S/NA) resource application for a plurality of resource types;
decode at a mobile termination (MT) function of the IAB node, downlink control information (DCI) received from a parent DU (P-DU) function of a parent IAB node, the DCI including an availability indicator for at least one soft resource region associated with the frequency-domain H/S/NA resource application;
and
configure a downlink transmission by the DU function of the IAB node to a child MT (C-MT) function of a child IAB node or an uplink reception from a child DU (C-DU) function of the child IAB node using the at least one soft resource region based on the availability indicator;
and
memory coupled to the processing circuitry and configured to store the configuration signaling and the DCI.
