Abstract: In some aspects, a user equipment (UE) may receive a configuration from a base station that indicates whether to use a first channel quality indicator (CQI) table from a first set of CQI tables associated with terrestrial network communications or whether to use a second CQI table from a second set of CQI tables associated with non-terrestrial network communications. The UE may transmit CQI feedback to the base station based at least in part on the configuration. The UE may transmit the CQI feedback using the first CQI table when the configuration indicates that the first CQI table is to be used or may transmit the CQI feedback using the second CQI table when the configuration indicates that the second CQI table is to be used.

Abstract: Methods, systems, and devices for wireless communications are described. In some networks, a user equipment (UE) may switch between serving beams of a transmitting device that are associated with different bandwidth parts of a radio frequency spectrum. To improve aspects of beam measurement and selection, a UE may be configured to support various techniques for beam measurement according to the different bandwidth parts. For example, a UE may receive a beam measurement configuration associated with one or more beams, and may monitor for reference signals associated with the beams using the different bandwidth parts. The UE may determine a channel quality of one or more of the beams based on the monitoring, and transmit a beam measurement report to the network in accordance with the beam measurement configuration. In some examples, such a report may be transmitted based on the UE determining that an event condition is satisfied.

Abstract: Methods, systems, and devices for wireless communications are described. A satellite may determine one or more sets set of resources for conveying reference signals to a user terminal. In one example, the satellite may determine a set of resources that includes multiple resource groups each associated with a respective frequency range. In another example, the satellite may determine multiples sets of resources and each set of resources may include resources within respective frequency range. Upon determining the set(s) of resources, the satellite may transmit an indication of the set(s) of resources to a user terminal.

Abstract: 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.

Abstract: Methods and apparatus for wireless communication include monitoring, by a user equipment, a signal quality value from at least one of a serving cell or a target cell. The methods and apparatus further include determining, at an expiration of an internal time to trigger (TTT) less than a network-configured TTT, that at least one of the signal quality value from the serving cell is below a serving cell threshold value, or the signal quality value from the target cell is above the signal quality of the serving cell by a comparative threshold value. Moreover, the methods and apparatus include triggering generation of a measurement report based on the determination.

Abstract: Systems and methods for predictive coordination of ego radar and interferer radar parameters are disclosed. In some aspects, a processor associated with a first radar system transmitting a first radar waveform to detect a target may identify a presence of a second radar system transmitting a second radar waveform in a vicinity of the first radar system. The processor may further predict an upcoming interference by the second radar waveform of the detection of the target by the first radar system. In addition, the processor may, in response to the predicting the upcoming interference, determine an adjustment to a first parameter of the first radar waveform and/or to a second parameter of the second radar waveform.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration to perform cooperative radar sensing. The configuration may indicate resources for the first UE to use to communicate radar measurement reports. The UE may receive, from another UE on the identified resources, a radar measurement report that includes values for one or more radar measurement parameters for a first radar target and a time stamp associated with the values. The UE may identify a second set of values for the radar measurement parameters (e.g., its own measurements, or measurements received from a third UE in another radar measurement reports). The UE may generate a combined set of values for the radar measurement parameters for each time stamp by combining the first set of values and the second set of values.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving a first message comprising a configuration for reconstructing a bandwidth part (BWP) for a network entity. The BWP may be used on a non-terrestrial beam of a non-terrestrial entity. The method also includes reconstructing a BWP of the BWPs based on the configuration. The method further includes switching from a current BWP to the reconstructed BWP to communicate with the network entity, e.g., non-terrestrial entity.
