Abstract:
Methods, systems, computer-readable media, and apparatuses are described for reporting, in support of positioning a UE, information about consistencies of positioning reference signal (PRS) measurements, PRS resources, PRS resource sets, or transmission and reception points (TRPs). In some embodiments, a UE receives PRS resources from TRPs and performs PRS measurements based on the PRS resources. The UE determines whether certain PRS measurements, PRS resources, PRS resource sets, or TRPs contribute to a consistent position estimate and/or consistent positioning measurements. The UE reports to a device, such as to a location server, information about consistent groups, where each consistent group identifies a set of such consistent elements.
Abstract:
The disclosure provides various methods and apparatuses for obtaining data. A method includes positioning the apparatus in proximity to a point of interest (POI), wherein an extension portion of the apparatus extends towards the POI. The method also includes providing power to a sensor via the extension portion, and receiving data from the sensor via the extension portion. The sensor may be detached from or attached to the apparatus. The data may be received via a wired or wireless connection. The power may be provided via a wired or wireless connection. The method may also include moving the extension portion further towards the POI after positioning the apparatus in proximity to the POI. The method may also include retracting the extension portion after receiving the sensor data or after expiration of a time period during which no data is received from the sensor. The apparatus may be an autonomous drone.
Abstract:
A user equipment (UE) determines to activate a data session. The UE configures a data session activation request message to include an indication of an association with communication sessions of a given type (e.g., delay-sensitive communication sessions), and then transmits the data session activation request message to an access network. The access network determines to establish an aggressive paging cycle of a downlink channel for the UE based in part upon receiving a message (e.g., which can be different than the data session activation request message) that conveys the indication of the association to the access network. The access network sends at least one instruction for facilitating an allocation of the aggressive paging cycle to the UE, and the UE receives the at least one instructions and monitors the downlink channel accordingly.
Abstract:
Methods and apparatuses for multicasting within a wireless communications system are disclosed. In one embodiment a method of multicasting within a wireless communications system operating in accordance with a given wireless communication protocol includes monitoring multicast messages associated with a given multicast session in a first sector. A handoff occurs from the first sector to a second sector. It is determined whether the second sector is transmitting multicast messages associated with the given multicast session. Then, based on the determination, a registration request for the given multicast session within the second sector is transmitted on a reverse link access channel in an earlier slot than a next designated slot for registration requests as defined by the wireless communication protocol.

Abstract:
In an embodiment, a UE determines to transmit a message (e.g., an alert message, a call initiation message). Based on the type of the message to be transmitted, the UE selectively transmits supplemental data configured to prompt an access network to transition the UE to a dedicated channel state (DCS). In another embodiment, an application server configured to arbitrate communication sessions between UEs receives a message for transmission to a target UE. Based on the type of the message to be transmitted to the target UE, the application server selectively transmits, to a serving access network of the target UE, supplemental data configured to prompt the serving access network to transition the target UE to the DCS. In another embodiment, the access network selectively transitions a target UE to the DCS based on whether differently sized messages are received at the access network for transmission to the target UE.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE has received, from a network, a sufficient quantity of protocol data units (PDUs) to decode a frame. Accordingly, the UE may indicate, to the network, that the UE has decoded the frame. Similarly, the UE may determine that the network has received, from the UE, a sufficient quantity of PDUs to decode a frame. Accordingly, the UE may refrain from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the UE may receive, from the network, an indication to disable some feedback to the network. Accordingly, the UE may refrain from transmitting one or more feedback signals based at least in part on the indication. Numerous other aspects are described.
Abstract:
Methods, systems, and devices for wireless communications are described. A UE may receive outer coded downlink signaling via carrier aggregation, and may deactivate retransmission protocols and then selecting at least one of two different feedback modes. A first feedback mode may include a radio link control (RLC) status report mode (e.g., which may be referred to as mode 1, or RLC mode 1). A second feedback mode is a hybrid automatic repeat request (HARQ) feedback mode (e.g., which may be referred to as mode 2, or HARQ mode 2. The network may configure the UE with parameters for operating in mode 1, mode 2, or both, or the UE may select a feedback mode autonomously. The UE may refrain from transmitting additional feedback signaling, and retransmissions may be deactivated, resulting in improved power savings and more efficient use of system resources.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple transport blocks (TBs) representing an application data unit (ADU) from a base station. The base station may transmit an indication that the UE is to provide ADU level feedback. The UE may determine the ADU level feedback based on whether the ADU is successfully received and decoded or not. The UE may indicate the ADU level feedback for the TBs to the base station. The base station and the UE may communicate according to the ADU level feedback.
Abstract:
Methods, systems, and devices for wireless communication are described. A device (e.g., a user equipment (UE) or a base station) may communicate (e.g., receive or transmit) a set of service data units (SDUs) of an application data unit (ADU). The device may be aware of the set of SDUs corresponding to the ADU based on an identifier in a header of the set of SDUs. The device may determine that an SDU of the ADU is absent and proactively transmit a signal based on identifying the absent SDU. Signaling ADU awareness between distributed units (DUs) and a centralized unit (CU) of a base station is described. The CU may indicate that a set of SDUs correspond to an ADU via a user plane interface. For example, a header associated with the interface may include one or more bits identifying the ADU in a payload corresponding to the header.
