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.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a time period during which the UE is configured to receive grants scheduling communications for the UE, wherein the grants are associated with a first grant format type. The UE may determine that the grants include a feedback process identifier exceeding a threshold value. The UE may maintain a power saving state of a discontinuous reception procedure for a feedback process associated with the feedback process identifier during the time period based at least in part on the feedback process identifier exceeding the threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a waveform threshold for selecting a waveform type for transmitting a message of a random access procedure. The UE may select the waveform type for the message of the random access procedure based on the waveform threshold and a value associated with a power of signals received at the UE. The UE may transmit the message of the random access procedure to a network entity according to the waveform type selected for the message.

Abstract: Methods, systems, and devices for reducing latency for closed loop sidelink communications for non-terrestrial networks (NTNs) are described. In some examples, a first user equipment (UE) may transmit, to a network entity, a message requesting an allocation of sidelink resources for the first UE and an allocation of sidelink resources for a second UE. The first UE may receive, from the network entity in response to the request message, an indication of a first set of sidelink resources for the first UE. In some examples, the first UE may transmit one or more data messages to the second UE, including an indication of a second set of sidelink resources, an indication that the network entity may directly allocate the second set of sidelink resources, or both. In some example, the first UE may receive one or more data messages from the second UE on the second set of sidelink resources.

Abstract: Aspects described herein relate to receiving, from a network node, a first transmission for configuring a configured grant, wherein the configured grant allocates one or more resources associated with an uplink transmission process having a transmission process identifier, obtaining a first indication that the network node uses a fallback downlink control information (DCI) format, and modifying, based at least in part on obtaining the first indication and the transmission process identifier, the uplink transmission process. Other aspects relate to configuring a device for modifying the uplink transmission process, receiving uplink communications based on the modified uplink transmission process, and/or the like.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

Abstract: Techniques are described for supporting user equipment (UE) positioning in a non-terrestrial network (NTN). To allow calculating a position/location of a UE based on reference signal (RS) measurements to and from one satellite (or a terrestrial base station), a device may be configured to calculate a doppler measurement and a range measurement and report such measurements to be used by a location server to calculate a UE position. An example device may receive a first RS (with the first RS being one of a positioning reference signal (PRS) or a sounding reference signal (SRS)), receive a second RS associated with the first RS, calculate a doppler measurement based on one or both of the first RS or the second RS, and report the doppler measurement. The doppler measurement (such as a measured frequency offset) may be used by a location server to calculate a UE position on the earth surface.

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: 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.
