Abstract: Methods, systems, and devices are described for providing periodic CSI reports and/or aperiodic CSI reports to provide CSI for both anchor and non-anchor TDD subframes in eIMTA. Periodic CSI reports may be provided based on a reference configuration, and aperiodic CSI reports may be provided based on a time of reception of a CSI request and a reference configuration. A UE may determine to report anchor or non-anchor CSI through explicit or implicit signaling. Aperiodic CSI may be used for transmission of anchor subframe CSI reports and periodic CSI may be used for transmission of non-anchor subframe CSI reports, or aperiodic CSI may be used for transmission of non-anchor subframe CSI reports and periodic CSI may be used for transmission of anchor subframe CSI reports. A determination of the reference subframe for aperiodic CSI estimation may be based on a time of receipt of an aperiodic CSI request.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may detect a radio link failure between the UE and a master node of a dual-connectivity configuration. The UE may transmit, to a secondary node in the dual-connectivity configuration, an indication that the radio link failure has occurred. The secondary node may receive the indication of a radio link failure and transmit the indication of the radio link failure to the master node of the dual-connectivity configuration. The master node may identify a target node for the UE and perform a handover procedure of the UE from the master node to the target node.

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: Methods, systems, and devices for wireless communication are described. Various autonomous uplink control channel configurations may be used for unscheduled uplink transmissions. For example, a user equipment (UE) may initiate an unscheduled uplink transmission and may identify an autonomous uplink control channel configuration for the uplink transmission. The UE may transmit control information and data during an initial transmission time interval of a transmission opportunity according to the control channel configuration, where the control channel configuration control may include a number of different waveforms and payload configurations. For example, an autonomous uplink control channel configuration may include control information frequency division multiplexed or time division multiplexed with data and transmitted in one or more frequency interlaces. In some cases, the control channel configuration may include a symbol period for a clear-to-send signal, and one or more symbol periods used a guard period before the data transmission.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives, by a user equipment (UE) during a first subframe, an indication of a dynamic uplink / downlink (UL/DL) subframe configuration. The apparatus determines an uplink hybrid automatic repeat request (HARQ) timing based on an uplink reference subframe configuration and at least one of the dynamic UL/DL subframe configuration or a downlink reference subframe configuration. The apparatus selects an uplink subframe for communication based on the determined uplink HARQ timing.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for performing minimization of drive test (MDT) operations. For example, certain aspects provide a method for wireless communication. The method generally includes receiving, at a radio access network (RAN), a measurement configuration to start a trace of a user-equipment (UE), determining a transition of the UE to an inactive state, and sending one or more messages to coordinate the trace of the UE or indicate that the trace has failed in response to the determination.
