摘要： A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one configuration, the apparatus may be a UE. The UE receives PTM data from a base station. The UE attempts to decode the PTM data based on an identifier. The UE determines whether to transmit feedback information to the base station based on the attempt to decode the PTM data. In another configuration, the apparatus may be a base station. The base station transmits PTM data to a UE. The base station retransmits the PTM data to the UE based on feedback information associated with the transmitted PTM data.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a base station a measurement configuration signal comprising a measurement resource configuration associated with a cross-link interference signal strength measurement. The UE may perform the cross-link interference signal strength measurement for one or more UEs associated with one or more intra-frequency neighboring cells according to the measurement resource configuration, wherein the cross-link interference signal strength measurement is performed during an intra-frequency measurement gap. The UE may transmit a report of the cross-link interference signal strength measurement to the base station.

摘要： 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.

摘要： Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide a base station receiving an indication from a core network to serve multicast/broadcast traffic to one or more UEs. The base station may select a radio bearer mode from a plurality of radio bearer modes for delivery of the multicast/broadcast traffic to at least one UE of the one or more UEs. For example, the base station may select a multicast/broadcast only mode, a mixed multicast/broadcast mode and unicast mode, or a unicast mode for service of the traffic. Dependent on the selected mode and/or quality of service, the base station may select a dedicated radio bearer (DRB) for communication of the traffic in a unicast mode (e.g., to a particular UE) or a multicast radio bearer (MRB) for communication of the traffic in a broadcast/multicast mode.

摘要： Generally, the described techniques provide for a core network signaling to a base station a delay budget configuration that indicates a determined latency for communications between a core network, base station, and a user equipment (UE). In some cases, the core network may determine a first variable delay budget between the core network and a base station based on capability information associated with the wireless communications system. The core network may transmit the delay budget configuration to the base station, where the delay budget configuration may include the first delay budget. The base station may be able to determine a delay between the UE and the base station based on the delay budget configuration. Using the delay budget configuration, the base station may then schedule communications with the UE.

摘要： 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.

摘要： Methods, systems, and devices for wireless communications are described that provide for user equipment (UE) camping in a virtual cell. A UE may camp in a virtual cell and may be in an idle mode or an inactive mode in the virtual cell. The UE may transition out of the idle or inactive mode and switch from camping in the virtual cell to connecting to a physical cell encompassed by the virtual cell through reselection, redirection, and handover procedures. The virtual cell may include a central unit and multiple distributed units, which may be configured in various physical implementations. Additionally, the virtual cell may be limited to broadcast only or selective unicast signaling.

摘要： 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.
