Abstract: An apparatus may be configured to receive an instruction indicating one of a machine-learning (ML) channel state information (CSI) feedback scheme associated with a first spectral efficiency or a non-ML CSI feedback scheme associated with a second spectral efficiency; and report the CSI feedback to a network node using the indicated one of the ML CSI feedback scheme or the non-ML CSI feedback scheme. Another apparatus may be configured to select one an ML CSI feedback scheme associated with a first spectral efficiency or a non-ML CSI feedback scheme associated with a second spectral efficiency; transmit, to the UE, an instruction indicating the selected one of the ML CSI feedback scheme or the non-ML CSI feedback scheme; and receive, from the UE, the CSI feedback that is associated with the selected one of the ML CSI feedback scheme or the non-ML CSI feedback scheme.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may support configured grant (CG)-small data transmission (SDT) procedures. To improve CG-SDT, the UE may validate measurement resources for timing advance (TA) validation and CG resource validation. The UE may receive a radio resource control (RRC) release message indicating CG resources and information that may be used for TA and CG resource validation, and the UE may receive measurement information based on one or more reference signals. In some cases, the UE may validate the measurement information and use it to perform a TA command (TAC) validation procedure. In some other cases, the UE may validate the measurement information and use it to perform a communication resources validation procedure. While in an inactive state, the UE may transmit an uplink communication using the validated TA and the validated communication resources.

Abstract: Method and apparatus for restrictions on sidelink transmission parameters for UEs. The apparatus receives a configuration of sidelink transmission parameters based on at least one of a height of the UE, a UE service range, or an area of a UE location. The apparatus communicates based on the sidelink transmission parameters and at least one of the height of the UE, the UE service range, or the area of the UE location. The sidelink transmission parameters comprise a height based condition based on a height threshold. The sidelink transmission parameters indicate for the UE to transmit sidelink transmissions using a first restriction to transmit a transport block when the UE height is greater than or equal to the height threshold and to transmit sidelink transmissions using a second message and a second restriction to transmit the transport block when the UE height is below the height threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) with a bandwidth part (BWP) indicator field with a value mapped to a set of BWPs for a set of scheduled cells, a mapping of the value to the set of BWPs being based at least in part on satisfaction, by at least one scheduled cell, of a condition relating to a quantity of BWPs configured for the at least one scheduled cell. The UE may communicate on the set of BWPs of the set of scheduled cells based at least in part on the mapping of the value to the set of BWPs. Numerous other aspects are described.
