Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a measurement regarding a plurality of bandwidth parts of a carrier of the user equipment based at least in part on a measurement object associated with the measurement; determine a cell quality regarding the plurality of bandwidth parts based at least in part on the measurement object; and/or transmit a measurement report identifying the measurement and/or the cell quality based at least in part on the measurement object. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for linear precoding in full-dimensional MIMO (FD-MIMO) systems. According to aspects, an eNB may compress a larger number of antenna elements to a smaller number of antenna ports. The eNB may use a port precoding matrix to transmit reference signals to a UE, receive feedback regarding CSI based on the reference signals, and transmit data to the UE, based on a mapping of multiple data layers and mapping of antenna ports to the physical antenna elements. Further, aspects include performing elevation beamforming by dynamically forming one or more vertical sectors based on UE feedback in the elevation domain.

Abstract: Aspects of the present disclosure describe receiving paging messages in wireless communications. A user equipment (UE) can receive one or more parameters for descrambling non-cell specific paging messages. The UE can receive, from one or multiple base stations, a non-cell specific paging message. The UE can descramble the non-cell specific paging message based at least in part on the one or more parameters.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a location of a reference subframe based on an A-CSI report uplink subframe, an A-CSI request downlink subframe, a reference delay, and a report delay. In an aspect, the reference delay is a first delay value before the A-CSI report uplink subframe, and the report delay is a second delay value between the A-CSI request downlink subframe and the A-CSI report uplink subframe. The apparatus determines a type of the reference subframe based on the location of the reference subframe and a subframe configuration, the type of the reference subframe being a flexible subframe or a fixed subframe. The apparatus measures at least one of a channel or interference based on the reference subframe and the type of the reference subframe. The apparatus sends, at the A-CSI report uplink subframe, an A-CSI report based on the at least one of the channel or the interference.
