Abstract: A first apparatus may communicate with a user equipment through a first active beam. The first apparatus may determine that beam tracking is to be performed with the UE, including identifying a new beam for communication between the UE and the apparatus. The first apparatus may perform beam tracking with the UE based on the determination that beam tracking is to be performed. The first apparatus may communicate with the UE through a second active beam based on the beam tracking.

Abstract: Methods, systems, and devices for wireless communication are described. Some examples provide for identifying a primary synchronization signal (PSS) sequence of a synchronization subframe, determining, for the synchronization subframe, an extended synchronization signal (ESS) sequence based at least in part on the PSS sequence and transmitting the synchronization subframe. Other examples provide for generating an ESS sequence for a synchronization subframe to be communicated to a UE, scrambling the ESS sequence based at least in part on cell-specific information associated with the base station and transmitting, to the UE, the scrambled ESS sequence in the synchronization subframe.

Abstract: An efficient way to perform power control and to communicate data with a base station is desired. According to an aspect, the apparatus generates a downlink grant for a device, the downlink grant indicating to the device subsets of uplink resources allocated for transmitting data segments and subsets of downlink resources for receiving power control commands for respective data segments, the subsets of the uplink resources being non-concurrent with the subsets of the downlink resources. The apparatus transmits the downlink grant to the device. The apparatus receives, from the device, a first uplink transmission in a first subset of the uplink resources based on the transmitted downlink grant. The apparatus generates a first power control command based on the received first uplink transmission. The apparatus transmits, to the device, the first power control command in a first subset of the downlink resources. The apparatus may be a base station.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a UE. The apparatus may receive a message from a base station. The message may indicate a first dedicated resource for downlink transmission, and the first dedicated resource may be associated with a scheduled downlink transmission from the base station. The apparatus may determine a second dedicated resource for uplink transmission based on the first dedicated resource for downlink transmission indicated in the message. The second dedicated resource for uplink transmission may be associated with the scheduled downlink transmission. The apparatus may determine whether to transmit an information message, to be used by the base station for transmitting the scheduled downlink transmission, on the second dedicated resource.

Abstract: When beamforming (e.g., via a millimeter wave system (mmW)) is used for wireless communication, a base station may transmit beams that are directed to certain directions. Due to the directional nature of the beams in the mmW system, an approach to determine a beam that provides a desirable gain is studied. The apparatus may be a user equipment (UE). The apparatus receives, from a base station, a plurality of signals through a plurality of beams of the base station, each of the plurality of beams corresponding to a respective antenna port of a plurality of antenna ports of the base station, where the plurality of signals include a plurality of beam reference signals, a plurality of beam refinement reference signals, a plurality of channel state information reference signals (CSI-RSs), or a combination thereof. The apparatus performs channel estimation for each beam of the plurality of beams from the plurality of antenna ports based on the plurality of signals.
