Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a loss of coherence associated with the UE. The UE may perform at least one adjustment to a transmission parameter or a reception parameter based at least in part on the indication of the loss of coherence. For example, the adjustment to the transmission parameter may include adjusting a transmit power, adjusting a transmit frequency, adapting a transmission time, changing an antenna port, or a combination thereof. Additionally, or alternatively, the adjustment to the reception parameter may include refraining from joint channel estimation across a plurality of slots, adjusting a downscaling parameter or a frequency tuning associated with at least one reception antenna, refraining from blind decoding, or a combination thereof. Numerous other aspects are described.

Indicating a loss of coherence in a wireless network

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may obtain, at an access stratum (AS) layer, an indication of an inter-satellite link (ISL) activation that is to take place at an activation time. The wireless communication device may receive communications. The wireless communication device may buffer the communications in a buffer at the AS layer. The wireless communication device may release the communications from the buffer to an upper protocol layer at a rate of release that is to change between a transition start time and the activation time. Numerous other aspects are described.

Buffer release for inter-satellite link transition

Certain aspects of the present disclosure are directed to techniques for hybrid automatic repeat request (HARQ) codebook design. For example, a user equipment (UE) configured for feedback processing may comprise a memory and a processor configured to receive, from a base station (BS), a first indication of a first feedback process type for providing feedback to the BS for a plurality of feedback processes of the UE. The memory and the processor may also be configured to receive one or more first downlink transmissions from the BS associated with at least one feedback process of the plurality of feedback processes. The memory and the processor may also be configured to transmit feedback or withhold transmission of feedback to the BS regarding decoding of the one or more first downlink transmissions according to the first feedback process type.

Hybrid automatic repeat request (HARQ) codebook design

Methods, systems, and devices for wireless communications are described. A base station and a user terminal may communicate via a relaying satellite in a non-terrestrial network. The non-terrestrial network may cause communication disruptions in hybrid automatic repeat request (HARQ) processes due to communication delays. Base stations and user terminals communicating via a satellite may implement dynamically configurable HARQ processes to avoid latency in a wireless communications system.

Dynamically configurable acknowledgement procedures

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying locations of respective random access channel (RACH) resources for a plurality of beams associated with a non-terrestrial network, wherein the plurality of beams are associated with respective frequency regions. The UE may perform a RACH procedure with regard to the selected beam using a RACH resource associated with the selected beam. Numerous other aspects are provided.

Random access channel frequency multiplexing for a non-terrestrial network

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

This disclosure relates to methods, devices, and systems for wireless communications, and more particularly uplink reference signal repetition for non-terrestrial networks. A user terminal in a non-terrestrial network may identify an uplink reference signal format that includes a comb-based pattern of subcarriers within a first orthogonal frequency-division multiplexing (OFDM) symbol and within a second OFDM symbol for transmission of an uplink reference signal. The user terminal may map the uplink reference signal to a first set of subcarriers within the first OFDM symbol and to a second set of subcarriers within the second OFDM symbol in accordance with the comb-based pattern. Thereby, the user terminal may transmit, to a base station in the non-terrestrial network, the uplink reference signal on the mapped subcarriers of the OFDM symbols, which may be transmitted coherently.

Uplink reference signal repetition for non-terrestrial networks

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine timing misalignment information for a timing misalignment between an uplink timeline and a downlink timeline associated with a non-terrestrial cell. The UE may transmit the timing misalignment information to a satellite associated with the non-terrestrial cell. Numerous other aspects are described.

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 system includes multi-zone heater with heating elements within a substrate support that correspond to multiple zones of the substrate support. A processing device coupled to the heating elements and to access a temperature matrix with multiple vectors corresponding to zones; determine a temperature map of the substrate support by multiplying the temperature matrix by a weight vector, the weight vector containing estimated weight values for each respective vector; determine a target thickness map of a film on a substrate based on an original thickness map and the temperature map, the original thickness map having data characterizing an original thickness across locations of an original film at a uniform temperature; iteratively update the estimated weight values so that the temperature map results in minimization to a standard deviation of thickness values within the target thickness map; and employ the estimated weight values as control values for the heating elements.

Multi-zone heater tuning in substrate heater

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

Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may receive control signaling from a scheduling device such as a base station which indicates a configuration for decoding control channel information at the UE using a single discrete transform process. In such cases, the configuration may be for decoding control channel information such as downlink control information (DCI) that is time multiplexed with data channel information in one or more symbols of a single carrier waveform. Using the configuration, the UE may decode the control channel information and the data channel information using the discrete transform process.

Control and data channel processing for higher bands

A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).
