    Abstract: Techniques for handover into eIMTA enabled cells are disclosed. In an aspect, a target cell reconfigures RRC connection with a UE after completed handover to enable eIMTA and/or CoMP for the UE. In another aspect, a target cell includes eIMTA configuration information in a handover command to a UE. In another aspect, the target cell may estimate a virtual cell identity to generate the eIMTA configuration information and delay scheduling transmissions to the UE by flexible subframes until after handover is complete and the correct eIMTA configuration information confirmed by measurement or else corrected by RRC connection reconfiguration. In other aspects, the target cell may determine the correct virtual cell identity before handover, either by measuring SRS of the UE, or by receiving information in a handover request indicating results of CSI-RS measurement, by the UE, of virtual cells of the target cell.

    Abstract: Certain aspects of the present disclosure provide techniques for a user equipment (UE) to efficiently provide feedback regarding preferred beams to a base station (BS) that transmits with different beams from different elevations. The techniques generally involve the BS transmitting first reference signals transmitted, using a plurality of elevation beams. The UE selects at least one preferred elevation beam based on the first reference signals and feeds this back to the BS. The BS transmits second reference signals using the preferred elevation beam and a plurality of azimuthal ports. The UE provides a second stage channel feedback to the base station, based on the second reference signals.

    Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment may determine at least one of: a first number of coefficients to be included in a first set of coefficients in a transfer domain that characterize compressed channel state information (CSI) for a first layer, or a first quantization scheme to be used to interpret the first set of coefficients. The UE may determine at least one of: a second number of coefficients to be included in a second set of coefficients in the transfer domain that characterize the compressed CSI for a second layer, or a second quantization scheme to be used to interpret the second set of coefficients. The UE may transmit a report that identifies the first set of coefficients and the second set of coefficients based at least in part on the determination(s). Other aspects are provided.

    Abstract: Some techniques described herein provide indication of a preferred scheduling mode for a user equipment (UE) based at least in part on an energy harvesting state of the UE. For example, the preferred scheduling mode may indicate a configured grant scheduling mode or a dynamic grant scheduling mode and/or one or more parameters associated with the preferred scheduling mode. For example, the one or more parameters may be based at least in part on an energy harvesting state of the UE. By indicating the preferred scheduling mode, the UE can selectively perform a transmission using a dynamic grant resource or a configured grant resource. Thus, the UE can request a dynamic grant resource when the UE is associated with a high energy level or a relatively fast charging rate, or a CG resource when the UE is associated with a low energy level ora relatively slow charging rate.

    Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE), including receiving a physical broadcast channel (PBCH) that conveys a master information block (MIB) that configures a first control resource set (CORESET) within an operating bandwidth below a threshold bandwidth, determining, based on a mapping of time and frequency resources indicated in the MIB, physical resources within the first CORESET of one or more physical downlink control channel (PDCCH) candidates, and monitoring the one or more PDCCH candidates for a PDCCH with information scheduling a system information block (SIB).

    Abstract: Methods, systems, and devices for wireless communication are described. A first wireless device may transmit one or more signals to a second wireless device using an antenna panel including antenna elements that are arranged in a hexagonal configuration. The signals may be transmitted using one or more directional beams for multiple-input multiple-output communications with the second wireless device, the directional beams generated based on the antenna elements in the hexagonal configuration. The first wireless device may receive a signal from the second wireless device, and in some cases, the first wireless device may transmit one or more reference signals via the one or more directional beams, the reference signals associated with a set of two or more antenna elements of the antenna panel of the first wireless device. The second wireless device may perform measurements of the reference signals and transmit a measurement report to the first wireless device.
