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: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously initiate a handover procedure and select a target base station for the handover procedure. The UE may measure a signal from the source base station or the target base station, or both, and the UE may determine whether specific criteria at both base stations are within a pre-configured range. If the criteria at both base stations are within the pre-configured range, the UE may identify the target base station as a potential candidate for a handover. Accordingly, when the UE determines that radio conditions with the source base station are deteriorating (or fall below a threshold), the UE may initiate a handover to the target base station autonomously and without specific direction from the source base station.

Abstract: New radio (NR) power headroom report (PHR) design for millimeter wave (mmWave) deployment is discussed. The power control process for mmWave may include beam-specific periodic PHR reporting and user equipment (UE)-specific event-trigger PHR reporting. The periodic PHR reporting may either provide a single PHR that includes power headroom information for each of the serving beams, or the UE may be configured to measure and report PHR for different beams in different slots. When reporting a single PHR with power headroom information for multiple serving beams, a beam index may be included in the reserved bits of the PHR. For the event-trigger PHR, the PHR reported based on a detected event trigger may provide power headroom information only for the current serving beam, or for all serving beams.

Abstract: Various aspects of the disclosure relate to delivering a limited amount of system information. For example, the delivery of system information may be divided into broadcasting a limited amount of the system information and using unicast signaling for delivery of the remaining system information. In some aspects, the delivery of a limited amount of system information may involve broadcasting a compressed PLMN ID list (e.g., broadcasting indications of PLMNs). In some aspects, the delivery of a limited amount of system information may involve broadcasting an indication of the version of system information that is valid for a cell. In some aspects, the delivery of a limited amount of system information may involve broadcasting multiple configurations of system information along with indications of each configuration. In some aspects, the delivery of a limited amount of system information may involve broadcasting compressed non-cell-related system information.

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: The present disclosure relates to systems and methods for a two-dimensional discrete Fourier transform based codebook for elevation beamforming. A two-dimensional discrete Fourier transform based codebook is determined for elevation beamforming. The codebook supports single stream codewords and multistream codewords. The two-dimensional discrete Fourier transform based codebook is generated by stacking the columns of the matrix product of two discrete Fourier transform codebook matrices. The codebook size may be flexibly designed based on required beam resolution in azimuth and elevation. A best codebook index is selected from the generated two-dimensional discrete Fourier transform based codebook. The selected codebook index is provided in a channel state information report. The channel state information report is transmitted to a base station.
