Abstract: Machine learning (ML) adaptation of any one of reference signal (RS) temporal density, RS frequency density, RS spatial density, or number of transmission/reception points (TRPs) that transmit RS provides configuration of lower RS densities or fewer TRPs that transmit RS without significant loss of throughput in appropriate circumstances. Determinations to switch from high density transmission to low density transmission, to reduce the number of antenna ports or TRPs that transmit RS, or to fallback to high density transmission may be made by the ML model, optionally with UE assistance information.

The sets of parameters include periodicity, start offset, and an on-duration timer. The method further includes determining an active period and an inactive period of the cell DTX or cell DRX based on the indication and the first information or an active period and receiving or transmitting channels or signals on the cell based on the determined active and inactive periods of the cell DTX or the cell DRX.

Abstract: Methods and apparatuses for an operation for triggering on-demand synchronous signal/physical broadcast channel block (SSB) or a system information block 1 (SIB1) in a wireless communication system. A method of a user equipment (UE) in a wireless communication system includes receiving a first physical downlink shared channel (PDSCH) from a base station (BS) and determining, based on an indication in the first PDSCH, that a set of synchronization signals and physical broadcast channel (SS/PBCH) blocks is activated for transmission from the BS. The method further includes determining a time domain offset with respect to the first PDSCH, determining that the set of SS/PBCH blocks is to be transmitted after the time domain offset and receiving a SS/PBCH block in the set of SS/PBCH blocks.

Abstract: A user equipment (UE) is configured to perform a method for measuring and reporting multi-beam operations. The UE includes a transceiver configured to communicate via a multi-beam operation with a base station. The UE further includes a processor operably connected to the transceiver. The processor is configured to at least one of: transmit, via the transceiver through a first set of antenna ports, one or more uplink (UL) reference signals (RSs), or receive, via the transceiver, one of: one or more downlink (DL) RSs transmitted by a base station (BS), or the one or more transmitted UL RSs, measure, via the transceiver using a second set of antenna ports, signal qualities of the one or more UL RSs and the one or more DL RSs for a time period, and perform measurement reporting of the measured signal qualities.

Abstract: Method and apparatuses for prediction based beam management in cellular systems. A method for a user equipment (UE) to report information related to a beam prediction is provided. The method includes receiving first information related to reception of reference signals (RSs) for beam measurements, second information indicating one or more reporting quantities related to the beam prediction, third information related to determining the one or more reporting quantities, fourth information related to transmitting the one or more reporting quantities, and the RSs for the beam measurements based on the first information. The method further includes measuring the RSs, determining the one or more reporting quantities indicated by the second information based on the third information and the measurement of RSs, and transmitting a channel with the one or more reporting quantities based on the fourth information.

Abstract: Doppler pre-compensated control and data signal(s) generated using first and second Doppler pre-compensation patterns, respectively, are transmitted. A signal indicating the Doppler pre-compensation patterns is transmitted. The Doppler pre-compensated control signals comprise synchronization signals, system information blocks (SIBs), a radio resource control (RRC) message, or a physical downlink control channel (PDCCH), and the Doppler pre-compensated data signals comprise a physical downlink shared channel (PDSCH). The signal indicating the Doppler pre-compensation patterns comprises one of an RRC message or a PDCCH, and may indicate absolute Doppler values or a difference between Doppler values. The PDCCH may indicate a time offset between the PDCCH PDSCH.

Abstract: Method and apparatuses for channel state information (CSI) feedback in cellular systems. A method for operating a user equipment (UE) to report CSI includes transmitting first information related to a capability of the UE to support machine learning (ML) based CSI reporting and second information related to a selection of a ML model for CSI reporting. The method further includes receiving third information related to configuring a first ML model for determining the CSI, fourth information related to processing a ML model output, fifth information related to reception of CSI reference signals (CSI-RS s) on a cell, and the CSI-RSs based on the fifth information. The method further includes determining, based on the third and fourth information and the reception of the CSI-RSs, a CSI report using the first ML model and transmitting a channel with the CSI report.

Abstract: A method for user equipment (UE) service handover from the serving cell to a target cell includes information regarding a handover timer and an associated handover execution condition. For scheduled handover to be performed upon expiration of the handover timer, the associated handover execution condition comprises one or more abort conditions for aborting the scheduled handover. For two-stage triggered handover to be performed upon receipt of a subsequent triggering message, the handover timer is a handover validity timer and the associated handover execution condition comprises receipt of the handover triggering message prior to expiration of the handover validity timer.

A method of a UE in a wireless communication system includes receiving higher layer parameters and determining DRX ON durations based on the higher layer parameters and reception occasions for physical downlink control channels (PDCCHs) based on the higher layer parameters, wherein a first PDCCH from the PDCCHs provides a downlink control information (DCI) format. The method further includes receiving the first PDCCH in at least one reception occasion from the reception occasions and determining based on an indication in the DCI format, whether to receive a second PDCCH in at least one DRX ON duration from consecutive NDRX DRX ON durations that are after the reception of the first PDCCH, wherein the indication in the DCI format is a bitmap of size NDRX, and NDRX bits in the bitmap are respectively associated with the NDRX DRX ON durations.
