Abstract: Techniques for autonomous uplink (AUL) transmissions are provided that allow for efficient use of shared radio frequency spectrum band resources. A user equipment (UE) may determine a duration of an AUL transmission and modify an uplink waveform or provide an indication to a base station of one or more channel resources that may be available for base station transmissions, in order to more fully utilize shared radio frequency spectrum band resources within a maximum channel occupancy time (MCOT). A base station may activate or deactivate AUL transmissions through downlink control information (DCI) transmitted to the UE. A UE and base station may exchange various other control information to provide relatively efficient autonomous uplink transmissions and use of the shared radio frequency spectrum band resources.

Abstract: In an aspect, an LMF component may determine to trigger positioning-related action(s) at a UE. The LMF component may request that a serving BS of the UE trigger the positioning-related action(s). The serving BS may transmit a DCI communication with a CSI request field (e.g., that triggers at least CSI reporting, or triggers positioning-related action(s) only). The CSI request field may further be associated with positioning-related information including at least one PRS configuration, at least one positioning measurement request, at least one location reporting request, or a combination thereof. The UE may perform the positioning-related action(s) based on the positioning-related information.

Abstract: Techniques are provided for processing frequency domain non—contiguous positioning reference signals. An example method for determining a time of arrival of a frequency domain non-contiguous positioning reference signal includes receiving the frequency domain non-contiguous positioning reference signal, determining a first estimate of the time of arrival (1204) based on a narrowband processing of the frequency domain non-contiguous positioning reference signal, performing a wideband processing of the frequency domain non-contiguous positioning reference signal based on the first estimate of the time of arrival, and determining a second estimate of the time of arrival (1214) based on the first estimate of the time of arrival and the wideband processing of the frequency domain non—contiguous positioning reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that configures a measurement gap for the UE. The UE may perform a first measurement and a second measurement in the measurement gap, wherein the first measurement and the second measurement are different types of measurements. The UE may transmit measurement information based at least in part on the first measurement or the second measurement. Numerous other aspects are provided.

Abstract: In an aspect, a UE and BS communicate data traffic in accordance with a first bandwidth part (BWP) configuration. The BS sends, to the UE in association with communication of a plurality of reference signals for positioning (e.g., PRS, SRS-P, etc.), an indication of a second BWP configuration that includes a different bandwidth than the first BWP configuration. The UE and BS communicate, for a duration of the communication of the plurality of reference signals for positioning, at least the plurality of reference signals for positioning in accordance with the second BWP configuration.

Abstract: Method and apparatus for switching between SS-TWR and DS-TWR. The apparatus reserves resources for transmission of a first SL-PRS in a first time slot. The apparatus transmits, to a second UE, the first SL-PRS within the first time slot. The apparatus receives, from the second UE, a second SL-PRS at a second time based on the first time slot and a response time associated with transmission of the second SL-PRS in response to the first SL-PRS. The apparatus measures a time difference between the transmission of the first SL-PRS and reception of the second SL-PRS to determine if a third SL-PRS is to be transmitted to the second UE.

Abstract: A parameter server located at a base station may coordinate federated learning among multiple user equipment (UEs) using over-the-air (OTA) aggregation with power control to mitigate aggregation distortion due to amplitude misalignment. The parameter server may select a first group of UEs for a first OTA aggregation session of a federated learning round based on a common received power property of each UE in the first group of UEs. The parameter server may transmit a global model to the first group of UEs. Each UE in the first group may train the global model based on a local dataset and transmit values associated with the trained local model. The parameter server may receive, on resource elements for the first group of UEs, a first aggregate amplitude modulated analog signal representing a combined response from the first group of UEs.
