Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node of a wireless network may transmit, by a first distributed unit (DU) of the first node to a central unit (CU), a second DU of another node in the wireless network, a user equipment in the wireless network, or a child node of the first node, an indication of a suggested resource pattern for the DU. The first node may transmit or receive a communication in the wireless network based at least in part on a resource pattern that is received in connection with transmitting the indication. Numerous other aspects are described.

First claim

What is claimed is:

1. A first node for wireless communication, comprising:
memory; and
one or more processors, coupled to the memory, configured to:
transmit, by a first distributed unit (DU) of the first node to a central unit (CU), a second DU of another node, a user equipment, or a child node of the first node, an indication of a suggested resource pattern for the DU,
wherein the suggested resource pattern for the DU is based at least in part on aligning non-available resources with a channel sensing failure pattern or based at least in part on interference or slot information for other DUs; and

transmit or receive a communication based at least in part on a resource pattern that is received in connection with transmitting the indication.

2. The first node of claim 1 , wherein the one or more processors are configured to generate the suggested resource pattern to conserve power based at least in part on one or more of a type of energy source, a level of remaining energy, a channel condition, a traffic condition, an interference condition, or an uplink buffer status report.

3. The first node of claim 1 , wherein the one or more processors are configured to generate the suggested resource pattern based at least in part on aligning the non-available resources with the channel sensing failure pattern.

4. The first node of claim 1 , wherein the one or more processors are configured to generate the suggested resource pattern based at least in part on the interference or the slot information for the other DUs.

5. The first node of claim 1 , wherein the suggested resource pattern indicates one or more of: a resource the DU is to use, a resource the DU is to not use, or a resource that is to be used based at least in part on a condition being satisfied.

6. The first node of claim 1 , wherein the suggested resource pattern is specified for a DU cell, a group of DU cells, a resource block (RB) group, a beam direction, a transmit receive point (TRP), a link between the first node and the child node, an access link, or a backhaul link.

7. The first node of claim 6 , wherein the suggested resource pattern includes a frequency domain resource pattern and an RB group configuration.

8. The first node of claim 1 , wherein the one or more processors, to transmit the indication of the suggested resource pattern, are configured to transmit the indication to the CU via an F1 application protocol interface or in a radio resource control (RRC) message via a mobile termination (MT) of the first node.

9. The first node of claim 8 , wherein the one or more processors are configured to receive a response from the CU after transmitting the indication of the suggested resource pattern to the CU, and wherein the one or more processors, to transmit or receive the communication, are configured to transmit or receive the communication based at least in part on the response.

10. The first node of claim 1 , wherein the one or more processors, to transmit the indication of the suggested resource pattern, are configured to transmit the indication to the child node via downlink control information (DCI), a media access control control element (MAC CE), a radio resource control (RRC) message, or a system information block (SIB) message.

11. The first node of claim 1 , wherein the one or more processors, to transmit the indication of the suggested resource pattern, are configured to transmit the indication to a parent node of the first node via uplink control information (UCI) in a physical uplink control channel (PUCCH), UCI in a physical uplink shared channel (PUSCH), or a media access control control element (MAC CE).

12. The first node of claim 1 , wherein the one or more processors, to transmit the indication of the suggested resource pattern, are configured to transmit the indication to the DU of the other node via an over-the-air (OTA) signal or a sidelink communication.

13. The first node of claim 1 , wherein the one or more processors are configured to generate the suggested resource pattern such that resources of the suggested resource pattern do not conflict with resources of a resource pattern received from the CU.

14. The first node of claim 1 , wherein the one or more processors are configured to generate the suggested resource pattern independent of whether resources of the suggested resource pattern conflict with resources of a resource pattern received from the CU.

15. A first node for wireless communication, comprising:
memory; and
one or more processors, coupled to the memory, configured to:
transmit, to a parent node of the first node or a distributed unit of a second node, an indication of a first resource pattern for a distributed unit of the first node;
transmit or receive an indication of one or more non-available (NA) resources in a serving cell for the first node based at least in part on a second resource pattern that corresponds to the indication of the first resource pattern; and
one or more of:
cancel a communication that is semi-statically or dynamically configured to use a resource indicated by the second resource pattern;
skip a downlink measurement of a signal in a resource that overlaps with the one or more NA resources; or
extend an evaluation period for the downlink measurement of the signal.

16. The first node of claim 15 , wherein the first node is a user equipment.

17. The first node of claim 15 , wherein the one or more processors, to receive the indication, are configured to receive the indication by a distributed unit of the first node or by a mobile termination of the first node.

18. A method of wireless communication performed by a first node of a wireless network, comprising:
transmitting, by a first distributed unit (DU) of the first node to a central unit (CU), a second DU of another node in the wireless network, a user equipment in the wireless network, or a child node of the first node, an indication of a suggested resource pattern for the DU,
wherein the suggested resource pattern for the DU is based at least in part on aligning non-available resources with a channel sensing failure pattern or based at least in part on interference or slot information for other DUs; and

transmitting or receiving a communication in the wireless network based at least in part on a resource pattern that is received in connection with transmitting the indication.

19. The method of claim 18 , further comprising generating the suggested resource pattern to conserve power based at least in part on one or more of a type of energy source, a level of remaining energy, a channel condition, a traffic condition, an interference condition, or an uplink buffer status report.

20. The method of claim 18 , further comprising generating the suggested resource pattern based at least in part on aligning the non-available resources with the channel sensing failure pattern or based at least in part on the interference or the slot information for the other DUs.

21. The method of claim 18 , wherein transmitting the indication of the suggested resource pattern includes transmitting the indication to the CU via an F1 application protocol interface or in a radio resource control (RRC) message via a mobile termination (MT) of the first node.

22. The method of claim 21 , further comprising receiving a response from the CU after transmitting the indication of the suggested resource pattern to the CU, wherein transmitting or receiving the communication includes transmitting or receiving the communic
