CHANNEL ESTIMATE OR INTERFERENCE REPORTING IN A WIRELESS COMMUNICATIONS NETWORK

Abstract

Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE), including receiving, from a network entity, an indication to report at least one of a channel quality indicator (CQI) or a pre-coding matrix indicator (PMI) for one or more future communications resources and sending, to the network entity, a channel state feedback (CSF) report indicating at least one of a predicted CQI or a predicted PMI for the one or more future communications resources prior to the one or more future communications resources occurring in time.

8. The method of claim 1, wherein the CSF report indicating the at least one of the predicted CQI or the predicted PMI indicates a single value for the at least one of the predicted CQI or the predicted PMI that corresponds to all of the one or more future communications resources.

9. The method of claim 8, wherein the CSF report further indicates a delta value for at least one of the one or more future communications resources, the delta value along with the single value corresponding to the at least one of the one or more future communications resources.

10. The method of claim 1, further comprising: transmitting, to the network entity, capability information of the UE indicating the UE is capable of predicting interference on future communications resources.

11. The method of claim 10, wherein the capability information comprises a maximum future time for which the UE is capable of predicting interference.

14. The method of claim 1, further comprising: transmitting, to the network entity, a message indicating a recommended configuration of a quasi-co-location (QCL) of a transmit beam of the network entity or a configuration of a receive beam of the UE to be used for predicting interference.

15. The method of claim 1, wherein the sending the CSF report is based on the receiving the indication.

16. The method of claim 1, further comprising predicting interference for the one or more future communications resources, wherein the at least one of the predicted CQI or the predicted PMI is based on the predicting the interference.

17. A method for wireless communications by a network entity, comprising: transmitting, to a user equipment (UE), an indication to report at least one of a channel quality indicator (CQI) or a pre-coding matrix indicator (PMI) for one or more future communications resources; andreceiving, from the UE, a channel state feedback (CSF) report indicating at least one of a predicted CQI or a predicted PMI for the one or more future communications resources prior to the one or more future communications resources occurring in time.

18. The method of claim 17, wherein the indication is transmitted in one of a radio resource control (RRC) message, a medium access control (MAC) control element (CE), or a downlink control information (DCI).

19. The method of claim 17, wherein the one or more future communications resources comprise one or more time and frequency resources, and wherein the indication comprises a configuration of the one or more time and frequency resources.

20. The method of claim 19, wherein the configuration comprises a time window for the one or more future communications resources.

21. The method of claim 20, wherein a start of the time window is defined relative to a measurement or reporting occasion.

22. The method of claim 19, wherein the configuration comprises a frequency range for the one or more future communications resources.

23. The method of claim 17, wherein the CSF report indicating the at least one of the predicted CQI or the predicted PMI indicates a separate value for the at least one of the predicted CQI or the predicted PMI for each of the one or more future communications resources.

24. The method of claim 17, wherein the CSF report indicating the at least one of the predicted CQI or the predicted PMI indicates a single value for the at least one of the predicted CQI or the predicted PMI that corresponds to all of the one or more future communications resources.

25. The method of claim 24, wherein the CSF report further indicates a delta value for at least one of the one or more future communications resources, the delta value along with the single value corresponding to the at least one of the one or more future communications resources.

26. The method of claim 17, wherein the one or more future communications resources comprise one or more beams.

27. The method of claim 26, wherein the indication comprises a configuration of a quasi-co-location (QCL) of a transmit beam of the network entity or a configuration of a receive beam of the UE to be used for predicting interference.

28. The method of claim 17, further comprising: receiving, from the UE, a message indicating a recommended configuration of a quasi-co-location (QCL) of a transmit beam of the network entity or a configuration of a receive beam of the UE to be used for predicting interference.

29. A user equipment (UE) configured for wireless communications, comprising: a memory comprising computer-executable instructions; and a processor configured to execute the computer-executable instructions and cause the UE to: receive, from a network entity, an indication to report at least one of a channel quality indicator (CQI) or a pre-coding matrix indicator (PMI) for one or more future communications resources; andsend, to the network entity, a channel state feedback (CSF) report indicating at least one of a predicted CQI or a predicted PMI for the one or more future communications resources prior to the one or more future communications resources occurring in time.
