Methods for inter-carrier sbfd configurations

A wireless transmit/receive unit (WTRU) comprising:

• a transceiver;
• and
• a processor;
• wherein the transceiver and processor are configured to:
• receive first configuration information, including multi-cell duplexing configuration information, wherein the multi-cell duplexing configuration information indicates a first reference cell and a linked cell, wherein the first reference cell is included in a set of one or more reference cells;
• receive, from a network, second configuration information comprising an inter-cell frequency gap threshold and information associated with the set of one or more reference cells;
• on a condition that a frequency gap between the reference cell and the linked cell is less than the inter-cell frequency gap threshold, determine, based on the received second configuration information, a subband non-overlapping full duplex (SBFD) configuration for the linked cell;
• and
• apply, to the linked cell, the determined SBFD configuration.
