    Abstract: Apparatuses and methods for transmission mode adaptation in New Radio (NR) with AI/ML assistance. A base station includes a transceiver configured to receive a set of input metrics. The set of input metrics comprises at least one metric derived from a channel state information (CSI) report. The base station further includes a processor operably coupled to the transceiver, the processor configured to determine, based on the set of input metrics, a first multiple-input multiple-output (MIMO) mode throughput prediction and a second MIMO mode throughput prediction, generate, based on the first MIMO mode throughput prediction, a predicted first MIMO mode throughput result, generate, based on the second MIMO mode throughput prediction, a predicted second MIMO mode throughput result, and select a MIMO mode based on the predicted first MIMO mode throughput result and the predicted second MIMO mode throughput result.

    Abstract: A method of operating a network entity includes transmitting, via a first TRP and a second TRP, a first DL RS; receiving from a UE, based on the first DL RS, first CSI; determining, based on the first CSI, a calibrated quadrant; transmitting, via the first TRP and the second TRP, a second DL RS based on the calibrated quadrant; and receiving from the UE, based on the second DL RS, second CSI. The method further includes, for N iterations, determining, based on the (N+1)th CSI, an adjusted calibrated phase; transmitting, via the first TRP and the second TRP, an (N+2)th DL RS based on the adjusted calibrated phase; and receiving from the UE, based on the (N+2)th DL RS, (N+2)th CSI. The method further includes, after the N iterations, determining, based on a most recently received (N+2)th CSI, a converged calibrated phase.

    Abstract: A method of operating a network entity includes receiving, from a UE, via a first TRP and a second TRP, a SRS, and estimating a channel based on the received SRS. The method further includes, for N iterations: transmitting, via the first TRP, a CSI-RS with a first polarization; transmitting, via the second TRP, the CSI-RS with a second polarization and a controlled phase offset; receiving, from the user equipment UE, a PMI report associated with the CSI-RS including co-phasing information between the first polarization and the second polarization; and updating the controlled phase offset, based on the co-phasing information. After the N iterations, the method further includes, based on the controlled phase offset and the co-phasing information, determining a phase mis-match for phase calibration between the first TRP and the second TRP.

    Abstract: A method of operating a network includes receiving an UL RS, estimating UL channels for a plurality of TRPS based on the UL RS, configuring first DL RS resources from an upper portion of a BWP, transmitting via the plurality of TRPs, a first beamformed DL RS from the upper portion of the BWP, and receiving via one or more of the plurality of TRPs, first CSI feedback based on the first DL RS. The method further includes configuring second DL RS resources from a lower portion of the BWP, transmitting via the plurality of TRPs, a second beamformed DL RS from the lower portion of the BWP, receiving via one or more of the plurality of TRPs, second CSI feedback based on the second DL RS, and determining a timing mis-match between the plurality of TRPs based on the first CSI feedback and the second CSI feedback.

    Abstract: A method performed by a network entity includes determining a target timing mismatch for a phase timing slope between first and second channel state information-reference signal (CSI-RS) resources, and determining, based on the target timing mismatch, a first band separation between a first calibrated phase for the first the second CSI-RS resource and a second calibrated phase for the first and the second CSI-RS resource. The method further includes determining a first frequency band for the first calibrated phase, and determining, based on the band separation, a second frequency band for the second calibrated phase. The method further includes determining, based on the band separation between the first calibrated phase the second calibrated phase, a first phase timing slope between the first the second CSI-RS resource, and performing joint transmission from a first TRP and a second TRP based on the first phase timing slope.

    Abstract: A method of operating a network entity includes receiving, via a first TRP and a second TRP, information associated with a SRS from a UE, and estimating a channel based on the information associated with the SRS. The method further includes, for N iterations: transmitting, via a first CSI-RS port from a CSI-RS resource, from the first TRP, a CSI-RS; transmitting, via a second CSI-RS port from the CSI-RS resource, from the second TRP, the CSI-RS with a controlled phase offset; receiving a PMI report associated with the CSI-RS including a measured phase offset between the first CSI-RS port and the second CSI-RS port; and updating the controlled phase offset, based on the measured phase offset. The method further includes, after the N iterations, based on the controlled phase offset and the measured phase offset, determining a phase mis-match for phase calibration between the first TRP and the second TRP.
