Abstract:
Example methods and apparatuses for managing polling in devices implementing proximity services are presented. For instance, an example method of polling management in a ProSe system is presented, which includes receiving, at a network entity, a polling message from a first UE. In addition, the example method may also include receiving, at the network entity and after receiving the polling message, one or both of a first location report associated with the first UE and a second location report associated with a second UE. Furthermore, the example method may include determining whether to generate a polling response message upon receiving one or both of the first location report and the second location report, wherein the polling response message includes a next polling time for the first UE that is based on a location reporting schedule associated with one or both of the first UE and the second UE.
Abstract:
Methods, systems, and devices are described for utilization of an unlicensed radio frequency spectrum band for performing a ranging procedure. Performance of the ranging procedure may be triggered by a signal transmitted in a licensed radio frequency spectrum band. While conventional ranging in Long Term Evolution (LTE) communications, for example, using the licensed radio frequency spectrum band may be limited to a 10 MHz bandwidth, using the unlicensed radio frequency spectrum band for ranging may allow use of a wider bandwidth, such as 100 MHz or greater. Use of the wider bandwidth may result in more accurate ranging measurements (e.g., time-of-arrival estimation).
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) of a group of UEs may receive, from a group member of the group of UEs, traffic information including a transmission schedule associated with traffic of the group member UE. The UE may determine a discontinuous reception configuration for the group of UEs based at least in part on the transmission schedule. The discontinuous reception configuration may include a discontinuous reception schedule for the group of UEs. The UE may transmit, to the group of UEs, the discontinuous reception configuration.
Abstract:
Methods, systems, and devices for wireless communications are described. A base station may configure one or more user equipments (UEs) with one or more timers, such that the UEs may switch directions for a communication mode for the duration of a timer and during a discontinuous cycle. The UEs may activate the timers and may perform the switching operation during the active duration of a discontinuous cycle. A UE may transmit a sidelink message during a transmission on duration (TX-On). The UE may activate a timer and switch to a receive mode. Similarly, the second UE may receive the sidelink message during a reception on duration (RX-On) and may activate the timer. The second UE may switch to a TX-On mode for an on duration of a TX-On cycle to transmit a sidelink response.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive first information identifying a value for a threshold parameter associated with a sidelink positioning procedure. The mobile station may transmit second information identifying a suitability for anchoring the sidelink positioning procedure, wherein the suitability is associated with the value for the threshold parameter. Numerous other aspects are described.
Abstract:
An apparatus may be a UE configured to receive, from a network entity associated with a machine learning procedure, a first indication that a first set of data elements transmitted by the wireless device at a first time is categorized as misinformation and that, based on the categorization of the first set of data elements as misinformation, the network entity will temporarily exclude data from the wireless device from propagation as input for a subsequent machine learning procedure. The apparatus may further be configured to receive a second indication of a set of criteria for requesting a reevaluation of the categorization and transmit, based on meeting one or more criteria in the set of criteria, a second set of data elements to the network entity at a second time.
Abstract:
Methods, systems, and devices for wireless communications are described. A multicast architecture may support flexible change between unicast and multicast operations and may support additional traffic types (e.g., Internet Protocol and Ethernet traffic). For example, the multicast architecture may include transmitting data over a shared multicast radio bearer (MRB) and/or specific data radio bearers (DRBs), a multicast user plane function (UPF) for supplying the multicast data to a base station, multicast data from different radio access networks (RANs), protecting the multicast data through creating a group key, ciphering the multicast data sent on the MRB using the group key, and transitioning the multicast data from a source RAN to a target RAN.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to perform groupcast transmission on a sidelink channel of a high frequency band, such as a millimeter wave (mmW) band. The UE may transmit, via a sidelink channel, beamformed repetitions of a packet in multiple directions corresponding to multiple quality of service (QoS) profiles configured for transmission of the packet. The UE may determine precoders to transmit the packet in the multiple directions. Each repetition of the packet may be associated with a separate hybrid automatic repeat request (HARQ) process. The UE may perform precoder cycling to transmit the packet in the multiple directions, and the UE may retransmit the packet in directions where the initial transmission was unsuccessful.
Abstract:
Methods, systems, and devices for wireless communication are described. An aerial vehicle (a transmitting device) may transmit control information that indicates a message type of a message. The message type may be one of multiple aerial vehicle broadcast message types, such as an aerial vehicle-to-aerial vehicle message type or an aerial vehicle-to-terrestrial user equipment (UE) message type. The transmitting device may transmit the message to a receiving device (e.g., another aerial vehicle or a terrestrial UE) in accordance with the indicated message type. For example, the transmitting device may transmit an aerial vehicle-to-aerial vehicle message to another nearby aerial vehicle or an aerial vehicle-to-terrestrial UE message to a terrestrial UE. As such, a receiving device may be aware of a message type and determine whether to decode the message accordingly.
Abstract:
Techniques for wireless communications are described. A first device may receive first control signaling that may indicate a second device in a wireless communications system. The first device may then identify, based on the received first control signaling, a set of devices for tracking the second device in the wireless communications system. In some examples, the first device may then transmit second control signaling to the identified set of devices for tracking the second device in the wireless communications system. The first device may then receive, based on the transmitted second control signaling, coordination information from the set of devices. The received coordination information may be associated with the second device. The coordination information collected by the set of devices may be used to predict changes in an environment surrounding the second device. By predicting dynamic changes in the environment, disruptions in wireless communication may be prevented.
