Resource management for wireless backhaul networks

An Integrated Access and Backhaul (IAB) node comprising:

• transmitter circuitry configured to transmit first information and second information on a resource allocation of OFDM symbols within one or more slots to another IAB node, wherein
• the transmitted first information includes a slot format indicator which indicates, for an OFDM symbol of the slot, whether the symbol is an uplink symbol, a downlink symbol, or a flexible symbol,
• the transmitted second information includes a resource indication of soft resources which indicates, for each OFDM symbol, whether the symbol may be available by the another IAB node,
• CRC bits of downlink control information (DCI) which indicates the slot format indicator are scrambled by a first radio network temporary identifier (RNTI), and
• CRC bits of DCI which indicates the resource indication of soft resources are scrambled by a second RNTI.

A base station comprising:

• transmitter circuitry configured to transmit first information and second information on a resource allocation of OFDM symbols within one or more slots to an Integrated Access and Backhaul (IAB) node,
• processor circuitry configured to:
• include, in the transmitted first information, a slot format indicator which indicates, for an OFDM symbol of the slot, whether the symbol is an uplink symbol, a downlink symbol, or a flexible symbol;
• and
• include, in the transmitted second information, a resource indication of soft resources which indicates, for each OFDM symbol, whether the symbol may be available by the IAB node;
• wherein
• CRC bits of downlink control information (DCI) which indicates the slot format indicator are scrambled by a first radio network temporary identifier (RNTI), and
• CRC bits of DCI which indicates the resource indication of soft resources are scrambled by a second RNTI.
