Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an aerial user equipment (UE) may measure a first offset associated with a downlink frame based at least in part on a time when a downlink signal is received from a terrestrial base station. The aerial UE may determine a second offset corresponding to a starting time for the downlink frame at the terrestrial base station. The aerial UE may transmit an uplink message in an uplink frame using a timing advance that is based at least in part on a value of the first offset and a value of the second offset relative to a starting time associated with a global navigation satellite system frame duration. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for allocating channel state information (CSI) processing unit (CPU) for user equipment (UE) initiated CSI. For example, the UE may receive an indication from a network entity (e.g., a base station or gNB) configuring the UE with a number of one or more CPUs allowed to be occupied for UE-initiated CSI feedback. The UE uses the at least one of the CPUs to calculate UE-initiated CSI feedback. The UE transmits at least one report including the UE-initiated CSI feedback if one or more conditions are met, such as when a mismatch between a CSI metric for a scheduled physical downlink shared channel (PDSCH) and a CSI metric calculated as part of the UE-initiated CSI feedback is equal to or exceeding a threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, from a transmitting device, a configuration indicating a set of orbital angular momentum (OAM) modes for joint reporting, where at least one of the set of OAM modes is associated with transmission via two or more of a plurality of sets of antennas arranged in a set of concentric circular arrays. The receiving device may transmit, to the transmitting device, a report indicating precoding information for each of at least a subset of the set of OAM modes, where the precoding information includes one or more first parameters common to the set of OAM modes and one or more second parameters for respective ones of the at least the subset of the set of OAM modes.

Abstract: Apparatus, methods, and computer-readable media for improving uplink data channel repetitions using multiple slot transmit time intervals are disclosed herein. An example method for wireless communication at a user equipment (UE) includes receiving scheduling downlink control information (DCI) indicating, in a time domain resource allocation (TDRA) field, a scaling parameter for a transport block size (TBS) of a physical uplink shared channel (PUSCH) transmission for transmission as PUSCH repetitions over a repetition unit comprising a plurality of single repetitions. The example method also includes transmitting the PUSCH repetitions with scaling based on the scaling parameter indicated in the scheduling DCI.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for configuring CSI-RS repetitions for CSI measurement in high Doppler scenarios. An example method generally includes receiving, from a network entity, a configuration identifying channel state information (CSI) reference signal (RS) (CSI-RS) repetitions over which a CSI report is to be generated, receiving CSI-RS repetitions according to the configuration, measuring CSI based on the received CSI-RS repetitions, and transmitting the CSI report including the measured CSI to the network entity.
