Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may transmit, to a second wireless node, a cross-link interference (CLI) management configuration message including a permutation indicator, 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 communicate with one or more third wireless nodes in accordance with the order of slot formats indicated to the second wireless node. Numerous other aspects are provided.

First claim

What is claimed is:

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.

2. The method of claim 1 , wherein the intended TDD DL-UL configuration includes an availability indicator corresponding to one or more resources identified in the intended TDD DL-UL configuration, wherein the availability indicator indicates that the one or more resources are available or not available.

3. The method of claim 2 , wherein a hard allocated resource or a soft allocated resource, of the one or more resources, is assigned an available value for the availability indicator.

4. The method of claim 2 , wherein the intended TDD DL-UL configuration indicates, for a resource, of the one or more resources, associated with a not available value for the availability indicator, whether the resource is assigned as a downlink resource, an uplink resource, or a flexibly assigned resource.

5. The method of claim 1 , wherein the intended TDD DL-UL configuration includes an indicator for a full-duplex or includes a bidirectional symbol slot format.

6. The method of claim 1 , wherein the Xn interface message includes a plurality of per-transmit receive point (TRP) configurations associated with a plurality of TRP identifiers or beam direction identifiers.

7. The method of claim 1 , wherein the intended TDD DL-UL configuration uses a message format associated with a TDD dedicated configuration message.

8. A first wireless node for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to cause the first wireless node to:
transmit, 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

communicate 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.

9. The first wireless node of claim 8 , wherein the intended TDD DL-UL configuration includes an availability indicator corresponding to one or more resources identified in the intended TDD DL-UL configuration, wherein the availability indicator indicates that the one or more resources are available or not available.

10. The first wireless node of claim 9 , wherein a hard allocated resource or a soft allocated resource, of the one or more resources, is assigned an available value for the availability indicator.

11. The first wireless node of claim 9 , wherein the intended TDD DL-UL configuration indicates, for a resource, of the one or more resources, associated with a not available value for the availability indicator, whether the resource is assigned as a downlink resource, an uplink resource, or a flexibly assigned resource.

12. The first wireless node of claim 8 , wherein the intended TDD DL-UL configuration includes an indicator for a full-duplex or includes a bidirectional symbol slot format.

13. The first wireless node of claim 8 , wherein the Xn interface message includes a plurality of per-transmit receive point (TRP) configurations associated with a plurality of TRP identifiers or beam direction identifiers.

14. The first wireless node of claim 8 , wherein the intended TDD DL-UL configuration uses a message format associated with a TDD dedicated configuration message.
