1. A method of wireless communication performed by a first wireless node, comprising:
transmitting, to a second wireless node and in an Xn interface message, an intended time division duplexing (TDD) downlink-uplink (DL-UL) configuration for a slot, and wherein the intended TDD DL-UL configuration for the slot includes:
a first information element (IE) identifying a first quantity of downlink symbols in the slot,
a second IE identifying a second quantity of uplink symbols in the slot, and
a third IE identifying a permutation indicator for the slot, wherein the permutation indicator indicates that an order of slot formats is an uplink-flexible-downlink order of slot formats or indicates that the order of slot formats is a downlink-flexible-uplink order of slot formats; and
communicating with one or more third wireless nodes in the slot in accordance with the first quantity, the second quantity, and the order of slot formats indicated to the second wireless node.
