Abstract: Methods, systems, and devices for providing feedback about radio link failure (RLF) events that includes information about directional beams. A user equipment (UE) may experience an RLF event and lose connectivity with a network. After the UE reestablish a radio resource control (RRC) connection with the network, the UE may transmit an RLF report that include information about directional beams, information about a master node and a secondary node in a dual-connectivity procedure, information associated conditional handover procedures, or information about service time interruptions, or a combination thereof. One or more base stations may be configured to transmit at least portions of the information in the RLF report to other base stations as part of a message that may be an example of an RLF indication or a handover report. The message may be transmitted over an X2 interface or an Xn interface.

Abstract: Systems and techniques are disclosed to reduce workload on base stations in a mobile network when content delivery networks cache content inside the network. A user equipment sets a flag only with those packets on the uplink which include requests that should be routed to the cache server inside the mobile network. The base stations perform deep packet inspection of those packets where flags have been set and forward other packets on to the rest of the relevant backhaul of the mobile network. After deep packet inspection, the base stations either route the packet to the cache server via an established connection or propagate the flag in an extension header to another network node for routing to the cache server. The resulting content is returned to the UE with the source address of the originally intended destination instead of the cache server, rendering the process transparent to the end user.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station (BS), a paging communication while the UE is in an inactive mode or an idle mode. The UE may transmit, to the BS and based at least in part on receiving the paging communication, a first communication as part of a random access channel (RACH) procedure. The UE may receive, from the BS and based at least in part on transmitting the first communication, a second communication that includes mobile-terminated downlink data, an indication of an uplink resource, and a radio resource control (RRC) release message. The RRC release message may cause the UE to remain in the inactive mode or the idle mode while receiving the mobile-terminated downlink data. The UE may transmit mobile-originated uplink data using the uplink resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support Ethernet frames that exclude a virtual local area network (VLAN) tag. A first device may receive a frame excluding a VLAN tag, and the first device may forward the frame to a second device. The second device may determine priority information (e.g., a default traffic class, a default frame priority) for the frame. In other examples, the first device may add a data tag (e.g., metadata indicating the priority information) to the frame. The first device may forward the frame to the second device, and the second device may remove the data tag from the frame. In either case, the second device may classify the frame according to a traffic class associated with a respective queue based on the priority information and may transmit the frame based on the traffic class and the respective queue.

Abstract: This disclosure provides systems, methods, and apparatuses for low latency handover between secondary nodes (SNs). In one aspect, a user equipment (UE) may receive a configuration for a plurality of SNs, receive a command to communicate via an SN of the plurality of the SNs, and determine a handover procedure that is to be used to establish a connection with the SN. The handover procedure may be a random access channel (RACH)-less or a two-step RACH procedure and is determined to be used based on a determination that uplink time synchronization is established with the SN.

Abstract: Certain aspects of the present disclosure provide techniques for a floating synchronization signal block measurement timing configuration (SMTC) for SSB-based radio resource management (RRM) in asynchronous networks, such as new radio (NR). A base station (BS) determines a floating SMTC for measurement of a target cell and provides the floating SMTC to at least one user equipment (UE) in the serving cell, wherein the target cell and the serving cell are asynchronous. The BS determines a measurement gap that covers the floating SMTC. The UE monitors in the measurement gap for a SSB transmission of the target cell based on the floating SMTC.

Abstract: Methods, systems, and devices for wireless communication are described. For example, the described techniques provide for a first device (e.g., a cellular modem or user equipment (UE)) mapping quality of service flows of a first radio access technology (e.g., cellular) to service classes of a second RAT (e.g., Wi-Fi). The first device may communicate mapping information that indicates the mapping to a second network device (e.g., a router). The first device and the second device may communicate various packets via the quality of service flows and the service classes.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to operate in a control mode. In some cases, the control mode may be an in active mode (e.g., a radio resource control (RRC) inactive mode). The UE may be configured to receive a control message from a network node. In some cases, the control message may include an uplink grant associated with a duration. The duration may relate to a timer, such as an expiration timer, for example. The UE may transmit an uplink transmission to the network node while operating in the control mode. The uplink transmission may be in accordance with the uplink grant and the duration. In some cases, prior to transmitting the uplink transmission, the UE may multiplex the uplink transmission with a second control message including an indication for the UE to remain in the control mode.

Abstract: A wireless device may receive a first synchronization signal block (SSB) in a radio frequency band of a first cell of a neighbor base station, and report a physical cell identifier (PCI) for the first cell to a serving base station. The serving base station may identify, based on the PCI report, whether a radio frequency band of the first SSB is in or off a synchronization raster, and determine whether to instruct the UE to report a global cell identifier (CGI) for the neighbor base station (e.g., CGI for the neighbor cell) based on the identification. The wireless device may identify CGI based system information obtained from the neighbor cell, system information obtained from a master cell associated with the neighbor base station, system information obtained from CGI broadcast from the neighbor cell, or system information requested from the neighbor cell using dedicated resources, based on the instruction.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication by a user equipment (UE). In one aspect, the UE is configured to select, by a user equipment (UE), a list of synchronization signal block (SSB) frequencies included in at least one message as a selected list of SSB frequencies. The UE is further configured to determine, based on whether a first frequency included in the selected list of SSB frequencies is an overlapping carrier or a non-overlapping carrier, whether to perform a new radio (NR) early measurement operation for the first frequency. The UE is also configured to identify a SSB-based measurement timing configuration (SMTC) based on a determination to perform the NR early measurement operation for the first frequency, and to initiate the NR early measurement operation for the first frequency using the identified SMTC.
