Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, a user equipment (UE) may be provided with wireless local area network (WLAN) identifiers associated with a public land mobile network (PLMN) for determining WLAN access points that support control plane termination at a fifth generation (5G) RAN for the PLMN. In another aspect, a network node may encapsulate system information in a broadcast message for transmission from a WLAN access point to a UE, and the UE may be configured to receive the system information from the WLAN access point in one or more modification periods. In yet another aspect, a network node may encapsulate a paging message for a broadcast or unicast transmission from a WLAN access point to a UE. In yet another aspect, UEs and network nodes may be configured to map traffic characteristics of traffic for a 5G bearer to WLAN access categories.

Abstract: In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

Abstract: Methods and apparatus for predicting wireless measurements based on virtual access points is described. In some embodiments, a location of a user equipment (UE) may be obtained, and given the location of the UE, an output may be generated using a machine learning model, the output including one or more predicted wireless measurements. The output may be indicative of a wireless channel in a multipath environment. In some variants, the machine learning model may have been trained by obtaining a training dataset including multipath components data and ground truth locations of a wireless device, and performing an optimization with respect to the multipath components data and the ground truth locations. In some implementations, a training output including a predicted multipath component may be produced during the training, and the optimization may include an iterative minimization of an error between at least the predicted multipath component and a labeled multipath component.

Abstract: Generally, the described techniques provide for a device determining or receiving signaling including a packet delivery time window configuration that indicates delivery windows within which transmissions may be held and/or delivery opportunities within which communications are expected to be transmitted. For example, the device may identify a packet delivery time window configuration for communications with another device. The packet delivery window configuration may indicate a periodicity, offset, start time, end time, and/or duration of the delivery windows, among other information. Based on the identified packet delivery time window configuration, the device may delay transmission of the data packet (e.g., for the duration of one or more configured delivery windows). At, for example, the end of the respective delivery window, the device may deliver the data packet to a network device for which the information of the data packet is to be used.

Abstract: Aspects relate to an allocation of periodic resources where use of the periodic resources is conditional. In some examples, a user equipment (UE) receives a periodic resource allocation along with an indication of a condition for using the periodic resources. For example, the UE may be allowed to transmit on at least one first resource of the periodic resources if the condition is true. Similarly, a base station (BS) may monitor for a transmission by the UE on the at least one first resource if the condition is true.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for sidelink channel occupancy time (COT) sharing request signaling in a wireless communication system. A sidelink transmitting user equipment (UE) transmits a COT sharing request to a sidelink initiator UE. The COT sharing request indicates to the initiator UE to initiate sharing of a COT acquired by the initiator UE with the transmitting UE. The initiator UE, in response to receiving the COT sharing request, determines to acquire the COT, and initiates COT sharing by transmitting, to the transmitting UE, COT sharing information including information to facilitate access to the COT by the transmitting UE. The transmitting UE, based on the COT sharing information received from the initiator UE, access the sidelink channel during the COT and transmits data over the sidelink channel.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) determines a positioning measurement of a first multipath component of a radio frequency (RF) signal transmitted by a transmission-reception point (TRP), determines a first additional positioning measurement of a second multipath component of the RF signal, determines a second additional positioning measurement of a third multipath component of the RF signal, and transmits a measurement report to a location server, the measurement report including at least the positioning measurement, the first additional positioning measurement, the second additional positioning measurement, and one or more parameters associated with the first additional positioning measurement and the second additional positioning measurement.

Abstract: Uplink control channel group and cross-carrier scheduling is disclosed for cooperative communications of a virtual UE. In an aspect, a UE reports a cooperative configuration with member UEs of a virtual UE and reports associations between a plurality of component carriers (CCs) allocated to a cell group and each member UE of the virtual UE. The UE may then receive an uplink control transmission configuration message dividing each member UE into an assigned uplink control transmission group and assign one or more component CCs into one or more CC sets, wherein each CC set is assigned to each uplink control transmission group. The UE may receive an uplink scheduling message from a serving base station, wherein the uplink scheduling message includes an uplink schedule for CCs within the CC set assigned to an uplink control transmission group associated with the UE. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support machine learning and may configure a user equipment (UE) for machine learning. The UE may transmit, to a base station, a request message that includes an indication of a machine learning model or a neural network function based at least in part on a trigger event. In response to the request message, the base station may transmit a machine learning model, a set of parameters corresponding to the machine learning model, or a configuration corresponding to a neural network function and may transmit an activation message to the UE to implement the machine learning model and the neural network function.
