Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of a subset of tracking reference signal (TRS) resource sets from a plurality of TRS resource sets. The UE may receive, from the network node, a TRS availability indication bitmap that indicates an availability of a TRS associated with the subset of TRS resource sets. The UE may determine that the TRS is available based at least in part on the TRS availability indication bitmap. The UE may receive, from the network node, the TRS based at least in part on the TRS availability indication bitmap indicating that the TRS is available. Numerous other aspects are described.

Indicating an availability of a tracking reference signal (TRS) associated with a subset of TRS resource sets

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.

Discontinuous reception for configured grant/semi-persistent scheduling

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.

Communication timing for sidelink relay between a ground UE and an aerial device

Apparatus, methods, and computer-readable media for facilitating reusing an air-to-ground communication system to support message-relaying for UEs in remote areas are disclosed herein. An example method for wireless communication at a user equipment (UE) includes establishing an access link with a terrestrial network. The example method also includes establishing a message layer of the access link for communicating with a payload deployed on-board an aerial device. The example method also includes communicating a communication with the aerial device using the message layer, the communication including a message to be provided to the terrestrial network or received from the terrestrial network.

Methods and apparatus to facilitate access link and ATG-based message relaying

A method of assessing a reported UE location includes: receiving, at a network entity, the reported UE location; obtaining, at the network entity, a first signal frequency difference indicating a first difference between a received frequency of a first signal received by the UE corresponding to a first transmit signal of a first transmit frequency transmitted from a first non-terrestrial-network node, and a received frequency of a second signal received by the UE corresponding to a second transmit signal of a second transmit frequency transmitted from a second non-terrestrial-network node that is separate from the first non-terrestrial-network node; and providing, by the network entity, a UE location assessment indication based on the first signal frequency difference and a second difference between an expected frequency of the first signal at the reported UE location and an expected frequency of the second signal at the reported UE location.

Reported mobile device location assessment

Certain aspects of the present disclosure provide techniques for user equipment (UE) positioning using one or more intelligent reflecting surfaces (IRSs). A method that may be performed by a UE includes for each IRS of the one or more IRSs: identifying a first IRS reflection center, measuring a first impulse response from the IRS to obtain a first measured impulse response representation, determining a first impulse response for a first ray reflected from the first IRS reflection center of the IRS, estimating a first position of the UE based on, at least, the first IRS reflection centers for each of the one or more IRSs and the first impulse responses for each of the one or more IRSs, and estimating a second position of the UE in an iterative manner until one or more conditions are satisfied.

Techniques for intelligent reflecting surface (IRS) position determination in IRS aided positioning

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network node, downlink control information (DCI) that schedules a downlink transmission and one or more repetitions of the downlink transmission. The DCI may indicate a first uplink resource for a first feedback message indicating whether the UE receives the downlink transmission and the one or more repetitions. Based on receiving the DCI, the UE may select a second uplink resource for a second feedback message indicating feedback that the UE received the DCI, where the second uplink resource occurs prior to the first uplink resource in a time domain. The UE may transmit the second feedback message on the second uplink resource. The UE and the network node may be part of a non-terrestrial network and, in some examples, may apply a configuration indicated in the DCI based on the second feedback message.

Method to transmit feedback in non-terrestrial networks

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.

User equipment positioning based on a non-terrestrial communication network

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.

Timing advance-based sidelink group scheduling

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.

Systems and techniques for compensation-based secure positioning

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.

Techniques for timing adjustment

Disclosed are techniques for wireless communication. In an aspect, a position estimation entity determines a set of position estimates associated with a set of user equipments (UEs), obtains first measurement information associated with a set of signals as reflected off of a target intelligent reflecting surface (IRS), determines a position estimate of the target IRS based on the set of position estimates and the first measurement information, and determines an orientation, relative to a common orientation reference frame, of the target IRS based on the set of position estimates and at least the first measurement information.

Determination of position and orientation of an intelligent reflecting surface

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.

Techniques for communicating over configured grant resources with high round trip times

A node including an RU and a control entity is disclosed. The node may receive, from a base station at a control entity of the node, an indication of at least one obstruction for communication via at least one reflective surface. The indication may indicate to the control entity to utilize an RU of the node and the at least one reflective surface for communication. The node may configure, upon receiving the indication of the at least one obstruction, the RU and the at least one reflective surface for communication with the base station. The node may forward communication received from, or forward communication to, the base station via the RU and the at least one reflective surface based on the at least one obstruction for communication.
