Abstract: Methods, systems, and devices for wireless communications are described. Some wireless devices may support a prediction capability for prediction-based control information. A first device may receive, from a second device, first control signaling that activates the predication capability of the first device to generate a set of one or more control parameters for communications. The second device may transmit second control signaling to the first device to indicate initial values of the control parameters and a channel condition model for the first device. The first device and the second device may generate a set of multiple values associated with the control parameters over a time period based on the initial values of the control parameters and the channel condition model. The first device and the second device may communicate during at least the time period according to the set of generated values associated with the control parameters.

Abstract: In some implementations, a non-terrestrial network (NTN) platform may transmit radio frequency (RF) signals toward earth, the RF signals comprising an orthogonal frequency-division multiplexing (OFDM) waveform with a plurality of symbols including a JCS symbol and one or more non-JCS symbols, wherein: the RF signals are incident on an area of the earth defining a footprint, and a duration of a cyclic prefix (CP) of the JCS symbol is a function of a width of the footprint. The NTN platform may receive, at the NTN platform, one or more reflections of the JCS symbol.

Abstract: Systems and techniques are provided for wireless communications performed at a network entity. For example, the systems and techniques can include obtaining, at the network entity, a target relative time difference (RTD). A transmission timing pre-compensation can be determined at the network entity between a first reference signal and a second reference signal, wherein the transmission timing pre-compensation is determined based on the target RTD and one or more network delay components. The first reference signal and the second reference signal can be transmitted using the transmission timing pre-compensation to offset the first reference signal from the second reference signal by the target RTD.

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) 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.

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) carrying information indicating an updated configuration for the UE, wherein the DCI is associated with a hybrid automatic repeat request (HARQ) process for which HARQ feedback regarding the DCI is disabled. The UE may transmit the HARQ feedback regarding the DCI based at least in part on the DCI carrying the information indicating the updated configuration. Numerous other aspects are described.

Abstract: A UE determines a group identifier based at least in part on a timing advance (TA) associated with the UE, the group identifier associated with at least the UE and a second UE and receives a sidelink resource allocation associated with the group identifier. The UE transmits sidelink communication using the sidelink resource allocation. A network node associates a UE with a group identifier based on a timing advance (TA) associated with the UE and transmits a sidelink resource allocation associated with the group identifier, the group identifier associated with at least the UE and a second UE.

Abstract: Methods, systems, and devices for wireless communications are described. A UE operating in an NTN may receive an indication of coverage information for a first cell associated with the NTN. The coverage information may indicate a coverage area supported by the first cell for wireless communications. The UE may transmit, based on location information of the UE and the coverage information, a message indicating a timing information associated with a measurement-based handover for the UE from the first cell to a second cell associated with the non-terrestrial network. For example, the message may include a recommendation for the UE to perform a non-measurement-based handover or an indication that the UE cannot complete the measurement-based handover before leaving the coverage area of the first cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate a connection release message via a first beam to release a connection between the UE and a network entity. The UE may obtain an indication associated with a second beam of a non-terrestrial network entity indicating a set of one or more beams associated with a paging early indication. The UE may monitor for the PEI paging message based on whether the first beam is included in the set of one or more beams. Alternatively, the UE may skip monitoring for the PEI based on the first beam being excluded from the set of one or more beams, and the UE may monitor for a paging message during a paging occasion. In some examples, the UE may receive a message indicating the set of one or more beams from the non-terrestrial network entity.
