    Abstract: The disclosed technology can include three dimensional (3D) beamforming for joint phase-time arrays (JTPAs). In some embodiments, a method for operating a BS is provided. The method includes receiving information from a plurality of user equipment (UEs) and identifying, based on the received information, azimuth and elevation information associated with the UEs. The method further includes determining at least two UEs of the plurality of UEs to serve based at least in part on the azimuth and elevation information of the at least two UEs, respectively, determining bandwidth allocations for the at least two UEs, respectively, and determining joint-phase-time array (JPTA) beams for the at least two UEs, respectively, based on the bandwidth allocations and the azimuth and elevation information of the at least two UEs, respectively. The method further includes transmitting information on the JPTA beams to the at least two UEs, respectively.

    Abstract: A method includes logically partitioning an antenna panel of a base station into multiple subpanels. The method also includes identifying multiple user groups for multi-user multiple-input multiple-output (MU-MIMO) spatial multiplexing, each user group comprising one or more user equipments (UEs). The method also includes assigning the user groups to the subpanels. The method also includes transmitting to the UEs via the subpanels, wherein each user group is served by one subpanel of the multiple subpanels.

    Abstract: A base station includes a controller configured to configure an MRS resource set comprising a group of MRS resources, each MRS resource comprising a set of MRS antenna ports. If at least two MRS antenna ports belong to a same MRS resource, then the at least two MRS antenna ports are quasi co-located with respect to a first set of QCL parameters, else if the at least two MRS antenna ports belong to a same MRS resource set, then the at least two MRS antenna ports are quasi co-located with respect to a second set of QCL parameters, and else the at least two MRS antenna ports are not quasi co-located with respect to either the first set or the second set of QCL parameters. The MRS is a CSI-RS for estimating a CSI and at least one of the first set and the second set of QCL parameters.

    Abstract: A method includes determining, at a first eNodeB (eNB) associated with a first cell of a network, that a first user equipment (UE) is to engage in a device discovery process. The method also includes coordinating parameters of the device discovery process with a second eNB. The second eNB is associated with a second cell of the network and with a second UE. The parameters define one or more resources to be used in the first and second cells during the device discovery process. The method further includes communicating at least some of the parameters to the first UE. The device discovery process includes a process in which the first UE identifies one or more other UEs with which the first UE is able to engage in device-to-device communications.

    Abstract: A multistage beamforming circuit includes a data unit that implements a frequency domain beamforming stage and a remote radio head that implements a time-domain broadband beamforming stage. The data unit implements the frequency domain beamforming stage by converting K received data streams into M precoding output streams in a frequency-domain. The data unit is configured to transform the M output streams to M OFDM time-domain signals. The remote radio head, or integrated radio unit is configured to implement a time-domain broadband beamforming stage by converting the M OFDM time-domain signals into N transmit streams of time-domain samples. The remote radio head, or integrated radio unit includes a transmit antenna array configured to transmit the N transmit streams that together form broadcast beams and user-specific beams. The antenna array includes a plurality of physical antennas. The number N of transmit streams is greater than the number M of precoding output streams.

    Abstract: A method includes selecting, by a base station, a partial search set based on one or more previous measurement reports from a user equipment (UE), the partial search set comprising a set of narrow beams that is a subset of an extended search set associated with an extended search. The method also includes performing, by the base station, a beam tracking search that sweeps the partial search set in order to select a next narrow beam. The method further includes communicating with the UE using the selected next narrow beam.
