Abstract: Aspects presented herein may enable a positioning entity (e.g., a UE, a base station, a TRP, or an LMF, etc.) to take changes in propagation delay into consideration when calculating RTT or measuring Rx-Tx timing difference for signals transmitted between a UE and a non-terrestrial device. In one aspect, a UE measures a plurality of PRSs transmitted from a non-terrestrial device. The UE calculates a propagation delay change between the UE and the non-terrestrial device based on a TDOA of the plurality of PRSs. The UE transmits, to an LMF or a location server, a UE Rx-Tx time difference associated with a UE positioning session and the propagation delay change.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for techniques for signaling control information in wireless communication systems based on orbital angular momentum (OAM) modes. One aspect provides a method for wireless communication by a transmitter. The method generally includes transmitting to a receiver, with a first orbital angular momentum (OAM) mode, a first control channel on a first time-frequency resource and transmitting to the receiver, with a second OAM mode, at least one of a data channel or a second control channel on a second time-frequency resource that at least partially overlap with the first time-frequency resource in at least one of time or frequency.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a channel state information (CSI) report configuration including configuration information that identifies a channel measurement resource associated with a first numerology and configuration information that identifies an interference measurement resource associated with a second numerology that is different from the first numerology. The UE may perform a channel measurement on the channel measurement resource associated with the first numerology and an interference measurement on the interference measurement resource associated with the second numerology. The UE may transmit, to the base station, a CSI report based at least in part on the channel measurement and the interference measurement. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for slot format configuration. A method that may be performed by a user equipment (UE) includes sending a message to a base station (BS) with UE capability information indicating one or more capabilities of the UE. The method includes receiving signaling from the BS indicating a semi-static slot format configuration based on the UE capability information, the slot format configuration including one or more slot format patterns and a cyclic shift (CS) associated with one or more slot format patterns. The method includes communicating with the BS based on the semi-static slot format configuration and the CS.

Abstract: A UE in one of an RRC idle mode or an RRC inactive mode may generate an emergency message including one or more of GPS coordinates, a timestamp, a UE ID, a personal ID of a user of the UE, an emergency level, or an emergency type, and transmit the emergency message to an NR-NTN. The emergency message may be transmitted in a dedicated time or frequency resource. The base station may receive the emergency message from the UE and forward the UE information to a network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may transmit, in a time-frequency resource occasion to a second wireless communication device, a first orbital angular momentum (OAM) signal in a first OAM mode. The first wireless communication device may receive, in the time-frequency resource occasion from the second wireless communication device, a second OAM signal, in a second OAM mode, that is orthogonal to the first OAM signal. Numerous other aspects are described.

Abstract: Methods, systems, and devices are described for wireless communications that support transmitting channel state information (CSI) feedback utilizing flexible uplink control resources. A method may include determining a size of a frequency subband corresponding to components of a CSI feedback report based on configuration signaling or a size of allocated uplink control resources. A method may include encoding a CSI report into a single packet and transmitting the single packet over uplink control resources. A method may include encoding a first plurality of components of a CSI report in a first packet, encoding a second plurality of components of the CSI report in a second packet, and mapping the packets to uplink control resources. A method may include transmitting a first plurality of components of a CSI report on a first slot and a second plurality of components of the CSI report on one or more subsequent slots.
