Determination of time and/or frequency domain configuration for simultaneous operation in integrated access and backhaul

A method performed by a network node, the method comprising:

• receiving a first resource configuration associated with a first multiplexing capability and a second resource configuration associated with a second multiplexing capability;
• receiving signaling activating one of a first multiplexing mode and a second multiplexing mode;
• determining whether to use the activated one of the first multiplexing mode and the second multiplexing mode based at least on one of the first multiplexing mode, the second multiplexing mode, the first resource configuration, the second resource configuration, and a fallback condition;
• and
• using one of the first resource configuration and the second resource configuration based on the determination.

A parent network node, the parent network node comprising:

• a radio interface configured to:
• receive, from a network node, an ability to exploit at least one of a first multiplexing capability and a second multiplexing capability;
• transmit, to the network node, a first resource configuration associated with the first multiplexing capability and the second resource configuration associated with the second multiplexing capability;
• transmit, to the network node, signaling activating one of a first multiplexing mode and a second multiplexing mode, the network node being configured to determine whether to use the activated one of the first multiplexing mode and the second multiplexing mode, and to use one of the first resource configuration and the second resource configuration based on the determination, and
• processing circuitry in communication with the radio interface, the processing circuitry configured to:
• determine the activation of one of the first multiplexing mode and the second multiplexing mode based at least in part on the received ability and operational conditions.
