Abstract: A UE transmits a sidelink synchronization signal in response to a communication trigger, the sidelink synchronization signal including an indication of the communication trigger to be provided to a network. The UE receives a sidelink message from an aerial device in response to the sidelink synchronization signal. An aerial device receives, from a UE, a sidelink synchronization signal including an indication of a communication trigger associated with communication for a network. The aerial device transmits a sidelink message to the UE in response to reception of the sidelink synchronization signal that includes the indication of the communication trigger.

Abstract: Methods, systems, and devices for wireless communications are described in which a block error rate (BLER) in non-terrestrial network (NTN) communications may be reduced through coverage enhancement techniques. Coverage enhancement techniques may include slot bundling for physical downlink control channel (PDCCH) communications, in which repetitions of a PDCCH may occupy multiple time-frequency locations spanning multiple slots. Such slots can be consecutive or non-consecutive, and in some cases multiple repetitions of the PDCCH may be provided within the same slot. The pattern of the time-frequency locations of repetitions may be periodic or non-periodic. Further, the repetitions can be exact copies, or different redundancy versions of the same encoded DCI. Additionally, repetitions of uplink or downlink shared channel communications, uplink or downlink control channel communication, broadcast channel communications, or any combinations thereof, may be provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a coordinate switch indication that indicates that the UE is to calculate a first value of a new ephemeris coordinate of a plurality of coordinates. The UE may calculate the first value of the new ephemeris coordinate based on one or more other ephemeris coordinates of the plurality of ephemeris coordinates and may generate ephemeris information, associated with a non-terrestrial communication device, based on the calculation of the first value of the new ephemeris coordinate. The UE may communicate with the non-terrestrial communication device based on the ephemeris information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) or a base station may generate a discrete Fourier transform (DFT) waveform from separate DFT inputs of data content, a guard interval (GI) sequence, and tail suppression samples. The UE or the base station may generate a first communication with the DFT waveform using an inverse fast Fourier transform (IFFT) operation. The first communication may include, in a time domain, a data signal corresponding to the data content and a GI-based tail signal that corresponds to the GI sequence and that is suppressed with a tail suppression signal based at least in part on the tail suppression samples. The UE or the base station may transmit the first communication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may receive, from a first wireless communication device on a first communication channel, a first communication that is configured with at least one guard interval (GI) sequence of a first GI type. The receiving device may receive, from the first wireless communication device or a second wireless communication device on the first communication channel or a second communication channel, a second communication that is configured with at least one GI sequence of a second GI type. Numerous other aspects are described.

Abstract: The apparatus may be a device at a UE or a base station. The UE (or base station) may be configured to measure a phase noise of a first local oscillator associated with a first port. The UE (or base station) may further be configured to configure, based on the measured phase noise, an allocation of a first set of one or more REs of a PUSCH (or PDSCH) for at least one PT-RS associated with the first port. The first set of one or more REs may include multiple layers associated with a multiple-layer single-carrier waveform transmission. The UE (or base station) may also be configured to transmit, to a base station (or a UE), the PUSCH (or PDSCH) including the at least one PT-RS, the at least one PT-RS being transmitted via the configured allocation of the first set of one.

Abstract: Certain aspects of the present disclosure provide techniques for waveform parameters adaptation. Aspects provide for adapting waveforms to account for impairments that can occur when communicating in a high frequency band. A method that may be performed by a base station (BS) includes detecting one or more impairment conditions. The method includes determining a plurality of waveform parameters to adapt in response to the detected one or more impairment conditions. The method includes signaling the plurality of adapted waveform parameters to a user equipment (UE).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.
