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: Certain aspects of the present disclosure provide techniques performing measurement reporting. One aspect is a method for performing measurement reporting at a user equipment, including: receiving, from a master node, a message comprising a measurement configuration for a secondary node; entering an inactive state; performing measurements according to the measurement configuration for the secondary node immediately after entering the inactive state; generating a measurement report based on the measurements; transmitting, to the master node, an RRC resume request message; receiving, from the master node, an RRC resume message comprising a request for measurement reporting; and transmitting, to the master node, an RRC resume complete message comprising the measurement report; and receiving data from the secondary node.

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: Methods, systems, and devices for wireless communications in a multiple bandwidth part environment are described. In response to a serving beam failure in an active bandwidth part, the UE may determine a level of support provided by the active bandwidth part for a random access procedure, and may determine a contingency (e.g. fallback) bandwidth part that supports the random access procedure. In some cases, the UE may identify the contingency bandwidth as an initial bandwidth part used by the UE for a prior random access procedure. In some cases, the base station may send to the UE, an explicit indication of the contingency bandwidth part. In some cases, the UE may identify the contingency bandwidth part based on a reference signal. Upon determining the contingency bandwidth part, the UE may perform the random access procedure using the contingency bandwidth part.

Abstract: Techniques and apparatus for a control plane design for bandwidth part (BWP) in new radio (NR) are provided. One technique includes sending information with an indication of a BWP capability of a user equipment (UE) to a base station (BS). A configuration from the BS indicating a set of BWPs available to use for communication is received in response to the indication. Communications are performed on at least one of the set of BWPs. Another technique includes receiving information having an indication of a BWP capability of the UE. A configuration indicating a set of BWPs available for the UE to use for communication is determined. The configuration is sent to the UE.

Abstract: NPRACH suffers from false alarms in which a base station detects and cannot distinguish an NPRACH signal that is intended for a different base station. An NPRACH may include a cell specific frequency shift pattern over repetitions and/or a repetition level scrambling sequence that enables a base station to more accurately detect NPRACH. An apparatus generates an NPRACH signal comprising multiple repetitions, wherein each repetition comprises multiple symbol groups. The apparatus may apply a different frequency shift between repetitions of the NPRACH signal. The frequency shift may comprise a cell specific random frequency shift pattern applied over each repetition. The apparatus may apply a repetition level scrambling sequence to the NPRACH signal, wherein a single scrambling sequence is applied to a set of repetitions comprised in the NPRACH signal. The apparatus transmits the NPRACH to a serving cell.
