Abstract:
Methods, systems, and devices are described for access class barring (ACB) operations for device-to-device (D2D proximity service communications. An ACB parameter may be defined and assigned to UEs that is associated with discovery or communication operations for normal and high priority user equipments (UEs). The UE may identify a resource for D2D proximity service communications and, when not barred, send a radio resource control (RRC) connection message requesting the available resource. An establishment cause may be defined and included in the RRC connection request message that corresponds to the ACB parameter.
Abstract:
Methods, systems, and devices are describe for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a group identity parameter associated with a multicast transmission of multimedia content. The first wireless device may map the identified group identity parameter to an identification parameter associated with at least one proximity service (ProSe) relay wireless device. The first wireless device may receive the multicast transmission of the multimedia content via the at least one ProSe relay wireless device based on the mapping of the identified group identity parameter to the identification parameter.
Abstract:
A station (STA) receives a schedule from a reference device in a wireless network. The schedule provides a measurement time for each of one or more wireless channels. The STA tunes to a first channel of the one or more wireless channels in accordance with the schedule. While tuned to the first channel in accordance with the schedule, the STA receives a first message from a first access point (AP). The first message, which includes a time-of-departure timestamp from the reference device, is time-stamped with a time-of-arrival timestamp. The STA receives an indication of a time at which the reference device received the first message from the first AP. The STA determines its position based in part on the time-of-departure timestamp, the time-of-arrival timestamp, and the time at which the reference device received the first message.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a node, a request for a security key for sidelink connectionless groupcast communication that is performed without a radio resource control connection between UEs. The request may indicate a distance from the UE for using the security key. The UE may receive, from the node, information that indicates the security key. Numerous other aspects are described.
Abstract:
Techniques described herein provide for leader selection of a group of vehicles, based on inter-vehicle communications. According to embodiments, a host vehicle can determine it qualifies to be the leader of a potential group by comparing vehicle information of other cars in the potential group with its own vehicle information. Once the determination has been made, the host vehicle can then send a request to be the group leader to the other vehicles. If the other vehicles accept, the host vehicle can initiate group formation. Otherwise, another vehicle can reject the request and send its own request to become the group leader, reinitiating group leader negotiation until a group leader is determined.
Abstract:
Location services for a user equipment (UE) are supported with a Network Exposure Function (NEF) serving as a focal point for any location request. An entity that needs the location of the UE sends a location request to the NEF in the home PLMN or Visited PLMN for the UE. The location request includes, e.g., a type of location request, a required location accuracy, a required response time or some combination of these. The NEF determines whether to use a Gateway Mobile Location Center (GMLC) or a serving Access and Mobility Management Function (AMF) for the UE to obtain the UE location based on the content of the location request and sends the location request to the GMLC or serving AMF accordingly. Additionally, if the serving AMF is used, a serving base station may obtain the UE location and send the UE location to the serving AMF.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a network entity, an indication of multiple transmission occasions for a transmission of a sidelink communication in an unlicensed spectrum. The first UE may transmit, to a second UE, the sidelink communication in a selected transmission occasion of the multiple transmission occasions for the transmission of the sidelink communication in the unlicensed spectrum. Numerous other aspects are described.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may initiate a radio resource control (RRC) layer signaling procedure between the UE and a target UE, include an upper layer signaling message in an RRC message based in part on the RRC layer signaling procedure, and transmit the RRC message including the upper layer signaling message to the target UE. Alternatively, upper layer signaling messages may be transmitted separately before or after the RRC layer signaling procedure.
Abstract:
Method and apparatus to determine a sidelink beam and associated power control parameter for sidelink communication. The apparatus initiates a beam pairing with a second UE, the first UE being a transmitting UE and the second UE being a receiving UE. The apparatus identifies a sidelink beam from a plurality of sidelink beams and at least one power control parameter for sidelink communication with the second UE. Different sidelink beams use different power control parameters. The apparatus communicates with the second UE via a selected sidelink beam and the at least one power control parameter.
Abstract:
Methods, systems, and devices for wireless communication are described. A first device may select a partition layer for partitioning a neural network model between the first device and a second device. The first device may implement a first sub-neural network model that includes the partition layer and the second device may implement a second sub-neural network model that includes a layer adjacent to the partition layer.
