Abstract: Certain aspects of the present disclosure provide techniques for reporting an indication of a PHR when the UE's assigned of UL resources is insufficient to transmit both UL data and a PHR. Additionally, aspects described herein introduce a negative PHR used to indicate the UE requires additional UL resources.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently retransmitting radio link control (RLC) protocol data units (PDUs) to one or more UEs. When a user equipment (UE) fails to receive or decode an RLC PDU transmitted by a base station, the UE may transmit a status PDU to the base station indicating that the UE failed to receive or decode the RLC PDU. The base station may receive the status PDU from the UE, and the base station may generate a repair PDU that includes redundant bits of the lost PDU (e.g., the PDU that the UE failed to receive or decode). The base station may then transmit the repair PDU to the UE, and the UE may use the redundant bits in the repair PDU (e.g., in combination with buffered PDUs) to attempt to correctly decode the lost PDU.

Abstract: Wireless communications systems and methods related to mobility with consideration for network slicing are provided. In one embodiment, a user equipment (UE) transmits in a first cell frequency of a network, a request for a network slice of the network that is not provided by the first cell frequency. The UE receives, in response to the request, an information for communicating in a second cell frequency of the network that provides the requested network slice. In one embodiment, a core network entity receives, from a network entity operating over a first cell frequency of a network, a request to provide a network slice of the network to a UE, the network slice not provided by the first cell frequency. The core network entity transmits, to the BS, information associated with a second cell frequency of the network providing the network slice.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a network node configures a quality of service (QoS) profile comprising one or more file-level QoS parameters, wherein the QoS profile applies to one or more files associated with a service flow associated with a user equipment (UE), wherein each file of the one or more files comprises one or more protocol data units (PDUs), and wherein a header of each PDU of the one or more PDUs of the file includes a file identifier and a file type of the file, and enforces the QoS profile on the one or more files.

Abstract: Certain aspects of the present disclosure provide techniques for file delivery feedback and/or application feedback for certain application services. An example method generally includes communicating files with a user equipment (UE), each of the files having a plurality of packets, determining that a delivery failure occurred for at least one of the files, and sending, to a server entity, a notification of the delivery failure.

Abstract: Various aspects of the disclosure relate to handover of a user equipment (UE) between a standalone mode of operation and a non-standalone mode of operation. For example, a UE may be handed-over from standalone to non-standalone, or vice versa. Moreover, this handover may be an inter-system handover (e.g., between an LTE core network and an NR core network).

Abstract: In an aspect, a slave UE and a master UE each establish an attachment to a core network of a cellular communications system. The slave UE obtains security credentials configured to encrypt and decrypt traffic between the slave UE and the core network. A D2D connection is established between the slave UE and the master UE (e.g., tethering). One or more communication functions are offloaded from the slave UE to the master UE, including at least one communication function with the core network for maintaining the attachment of the slave UE to the core network. Application-layer data is relayed to/from the slave UE over the D2D connection. In an aspect, either the slave UE or the master UE may perform encryption and decryption of control plane signaling using the slave UE's security credentials.

Abstract: This disclosure provides systems, methods, and apparatus for wireless communications that support fast user equipment (UE) handover between base stations. A UE may receive, from a source base station, a configuration for reference signal transmission at a set of uplink transmit power levels. The UE may transmit multiple uplink reference signal repetitions based on the configuration. The source base station may transmit a request message to a target base station to measure the multiple uplink reference signal repetitions. The target base station may select an uplink reference signal and measure a transmit power correction. The target base station may transmit an indication to the source base station of the selection and transmit power correction. The source base station may evaluate the indications and select the target base station. The source base station may forward to the indicated contents, and the UE may switch and synchronize with the target base station.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control signaling indicating a measurement configuration for minimization of drive test measurement and reporting supporting broadcast receptions within a single-frequency network. The UE may determine, based at least in part on the measurement configuration, a set of measurements for the single-frequency network. The UE may transmit a minimization of drive test report indicating the set of measurements.

Abstract: Aspects of the disclosure relate to a UE and a network device for wireless communication. The UE sends an indication to a network device indicating a capability of receiving a PWS signal and/or a delay requirement for receiving the PWS signal. The UE receives, from the network device, a configured DRX cycle value associated with the indication and a paging signal corresponding to the PWS signal associated with the configured DRX cycle value. The network device determines whether the UE is capable of receiving the PWS signal and whether the UE desires to receive the PWS signal within a duration. The network device configures a DRX cycle value based on the determination and sends, to the UE, the configured DRX cycle value and a paging signal corresponding to the PWS signal based on the configured DRX cycle value. Other aspects, features, and embodiments are also claimed and described.
