Abstract: The apparatus may be provided to improve a PAPR in at least one of a single-carrier FDM signal or DFT-s-OFDM. The apparatus may be configured to encode a set of information bits with a channel encoder; generate, based on a set of encoded bits from the channel encoder, a set of amplitude symbols using a distribution matching function; generate a set of modulated symbols based on the set of amplitude symbols; and transmit, to a second device, a signal based on the set of modulated symbols. An apparatus may be configured to receive, from a first device, a signal based on a set of modulated symbols and derive a set of encoded bits based on the received set of modulated symbols using a distribution matching function.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may operate by asynchronously transmitting code division multiple access (CDMA) uplink signals to a network entity. The UE may transmit the CDMA signals via an uplink channel that may be shared with orthogonal frequency multiplexing (OFDM) signaling transmitted by one or more other UEs. The UE may indicate to the network entity a capability for communicating with CDMA waveforms and may use CDMA waveforms based on transmitting the indication. The UE may also receive one or more parameters associated with using the CDMA waveforms, and may use CDMA waveforms based on the one or more parameters. The uplink channel may be a random access channel (RACH) and may support RACH transmissions, or may be a data channel and support data transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network may establish communications over a directional beam. The UE may receive, from the network, a configuration of one or more channel sounding messages for one or more directional beams, where each directional beam of the one or more directional beams is associated with a set of narrowband carriers, and each of the one or more channel sounding messages being configured for transmission on a narrowband carrier of the set of narrowband carriers. The UE may determine a trigger for transmitting the one or more channel sounding messaged based at least in part on the configuration and transmit, to the network, the one or more channel sounding messages on respective narrowband carriers in accordance with the trigger and the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A serving base station or a serving satellite may transmit a timing configuration to the UE based on a reference unit, such as a location at a beam center for a respective satellite, a threshold distance relative to the beam center for the respective satellite, a reference time, or any combination thereof. In some cases, the UE may monitor for one or more SSBs from the neighboring satellites according to the timing configuration and a respective propagation delay between the UE and each of the neighboring satellites. The UE may measure the SSBs according to the measurement gap and measurement window in the timing configuration. In some examples, the UE may perform a cell handover procedure or a cell reselection procedure based on measuring the SSBs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message from a first non-terrestrial network cell indicating cell synchronization information for a second non-terrestrial network cell. In some examples, the cell synchronization information may indicate whether the first non-terrestrial network cell and the second non-terrestrial network cell are synchronized at a reference point. Additionally, or alternatively, the cell synchronization information may indicate a timing offset value between a first uplink time synchronization reference point of the first non-terrestrial network cell and a second uplink time synchronization reference point of the second non-terrestrial network cell. The UE may calculate a timing associated with signaling from the second non-terrestrial network cell based at least in part on the cell synchronization information. The UE may receive one or more signals from the second non-terrestrial network cell based at least in part on the calculated timing.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating a time domain window (TDW) configuration including a start time of a TDW and a length of the TDW, where the TDW is a duration over which a network entity is scheduled to perform joint channel estimation. The UE may receive a timing advance (TA) command during the TDW indicating a TA value to apply to signaling. The UE may transmit the signaling in accordance with the TA value or independent of the TA value based on the UE prioritizing the TA adjustment or maintaining power consistency and phase continuity for DMRS bundling, respectively. The UE may determine whether to prioritize the TA adjustment or DMRS bundling for the joint channel estimation based on one or more parameters satisfying criteria.
