In some aspects, a client may receive an observed environmental vector feedback configuration associated with a reporting procedure for reporting updates corresponding to at least one observed environmental vector that is based at least in part on one or more features associated with an environment of the client, wherein the observed environmental vector comprises input for a first machine learning component that determines client specific parameters for use by a second machine learning component. The client may transmit an update corresponding to the at least one observed environmental vector based at least in part on the observed environmental vector feedback configuration. Numerous other aspects are provided.

Observed environmental vector feedback for wireless communication

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of at least one of a configured grant or a semi-persistent scheduling (SPS) configuration. The UE may transmit or receive, based at least in part on a modification to the at least one of the configured grant or the SPS configuration, wherein the modification is based at least in part on a change from a first time domain pattern to a second time domain pattern. The UE may receive and indication of the modification from the base station. Additionally, or alternatively, the UE may determine the medication based at least in part on at least one rule stored in a memory of the UE. Numerous other aspects are described.

Techniques are provided for authenticating a user based on ranging and biometric information. An example method for transmitting a ranging signal from a mobile device includes receiving biometric information from a user with the mobile device, generating a ranging signal including an indication of the biometric information with the mobile device, and transmitting the ranging signal with the mobile device.

Ranging with biometric information

Methods, systems, and devices for wireless communications are described. Feedback information associated with decoding downlink information may be reported in a first stage and a second stage. A size of the second stage may be restricted by an upper limit associated with an available set of uplink resources for transmitting the feedback information. Limiting the size of the second stage may include reducing a size of second information generated for the second stage, yielding third information for the second stage. The third information may be transmitted with first information generated for the first stage. Limiting the size of the second stage may also include generating second information having a reduced size based on determining that the upper limit may be exceeded. The reduced-size second information may be transmitted with the first information.

Two-stage feedback procedures

A UE may estimate a CLI channel state based on a ZP-SRS from a second UE. A network node may transmit to the UE, and the UE may receive from the network node, a CSI-RS. The UE may estimate a downlink channel state based on the CSI-RS from the network node. The UE may estimate one or more eCSF parameters based on the CLI channel state, the downlink channel state, two or more interference hypotheses, and at least one of a CPU specification, a timing specification, or a UE capability indication. The UE may transmit to the network node, and the network node may receive from the UE, an eCSF report based on the one or more eCSF parameters.

Disclosed are techniques for wireless communication. In an aspect, a first network node determines at least one positioning measurement based on a channel estimate of a positioning reference signal (PRS) transmitted by a second network node, and obtains measurement error feedback for at least the at least one positioning measurement, wherein the measurement error feedback is based on an expected positioning measurement corresponding to the at least one positioning measurement, and wherein the expected positioning measurement is based on a location of the first network node and a location of the second network node.

Measurement error feedback to enable machine learning-based positioning

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal indicating one or more reference signal resource sets, the one or more reference signal resource sets comprising at least a first subset of reference signal resources associated with a first reference signal switching configuration and a second subset of reference signal resources associated with a second reference signal switching configuration. The UE may receive a trigger signal activating at least the first reference signal switching configuration or the second reference signal switching configuration. The UE may transmit, based at least in part on the trigger signal, reference signals according to the first subset of reference signal resources or second subset of reference signal resources.

Support of flexible sounding reference signal switching capability

Full-duplex communication techniques are described. Some aspects may utilize full-duplex-slot formats, such as may be provided in addition to or in the alternative to uplink, downlink, and flexible slot formats. A full-duplex slot implemented in accordance with a full-duplex-slot format provides a slot in which the frequency band may be used for both uplink and downlink transmissions. Downlink and/or uplink transmissions of a full-duplex slot may occur in overlapping frequency bands or in adjacent frequency bands. A first wireless device may transmit slot signaling comprising one or more full-duplex-slot-indicator parameters. A second wireless device may base one or more full-duplex slot configuration determinations on a full-duplex-slot configuration. The second wireless device may apply one or more full-duplex-slot-indicator-parameter rules with respect to full-duplex-slot-indicator parameters for determining a full-duplex-slot format. Other aspects and features are also claimed and described.

Full duplex communication techniques

The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a user equipment (UE) and/or base station. In one aspect, the apparatus may configure a frame structure including a plurality of slots in a subframe, the plurality of slots including at least one of one or more downlink slots, one or more uplink slots, or one or more flexible slots, each of the one or more flexible slots including multiple subband resources. The apparatus may also signal configuration information of the frame structure including the plurality of slots. Additionally, the apparatus may communicate data via the frame structure including the plurality of slots.

Methods and apparatus for cross link interference mitigation

A method of wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a resource allocation for a first set of resources in a first frequency band that is disjoint from a second frequency band in a sub-band full duplex (SBFD) slot, and communicates with a network node using the first set of resources in the first frequency band and a corresponding second set of resources in the second frequency band. The method improves the resource allocation efficiency for scheduling resources over multiple disjoint sub-bands.

Sub-band full duplex (SBFD) allocation with disjoint sub-bands

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a first number of one or more transmit antennas supported by the UE for antenna switching and a second number of ports supported for uplink transmission that exceeds the first number of one or more transmit antennas. The UE may receive, based on the capability message, a sounding reference signal (SRS) configuration indicating a mapping between each SRS resource or SRS resource group and a respective bit sequence of a set of bit sequences. The UE may receive a control message comprising one or more bit sequences of the set of bit sequences indicating one or more SRS resources or an SRS resource group based on the mapping. The UE may transmit one or more SRS signals based on the control message.

Techniques for indicating sounding reference signal resources

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on an estimated cross link interference (CLI) at the UE. For example, a network entity may indicate, to a first UE and a second UE, transmission parameters of a multi-port CLI-reference signal (CLI-RS) that is associated with estimation of CLI channel between the first UE and the second UE. The network entity may indicate, to the first UE, one or more precoding parameters associated with uplink precoding at the second UE. The second UE may transmit the multi-port CLI-RS to the first UE, and the network entity may transmit a CSI-reference signal (CSI-RS) to the first UE. The first UE may transmit a report that includes CSI based on the multi-port CLI-RS, the CSI-RS, and the one or more precoding parameters.

Cross link interference based channel state information reporting

Certain aspects of the present disclosure provide techniques for fast adaptation of transmission properties of sounding reference signal (SRS) resource sets. A method that may be performed by a user equipment (UE) includes receiving sounding reference signal (SRS) configuration information, configuring the UE with one or more SRS resource sets, wherein each of the one or more SRS resource sets comprises one or more SRS resources; receiving signaling comprising a field indicating which of the one or more SRS resources in the one or more SRS resource sets are active and which of the one or more SRS resources in the one or more SRS resources sets are inactive; and transmitting one or more SRSs using only the one or more SRS resources that are active.

Fast adaptation of transmission properties of SRS resource sets

In an aspect, a communications node selects a reference device for a positioning procedure based on hardware group capabilities associated with reference devices involved in the positioning procedure (e.g., RTT, differential RTT, double differential RTT, TDOA, etc.). In another aspect, a distance between reference devices is estimated based on timing measurements of reference signal(s) for positioning. A hardware group delay associated with the reference devices is estimated based on (i) the estimated distance between the first and second reference devices, and (ii) a known distance between the first and second reference devices.

Reference device hardware group delay calibration

Disclosed are techniques for communication. In an aspect, a first UE determines information (e.g., from an external device, or via the first UE's own energy sensing) associated with scheduled uplink transmissions on a set of symbols by a second UE. The first UE performs measurements on at least some of the scheduled uplink transmissions during a first subset of the set of symbols where no DL signals are received by the first UE. The first UE receives at least one DL signal during a second subset of the set of symbols, and mitigates interference associated with the at least one DL signal based on the measurements.
