Abstract: Methods, systems, and devices for wireless communication are described. A network device, such as a base station, may transmit a set of reference symbols to a user equipment (UE). Each set of reference symbols may include two (or more) beamformed signals. The network device may receive, based on the set of reference symbols, a measurement report from the UE. The measurement report may include a co-phasing indicator associated with the set of reference symbols. The network device may identify, based at least in part on the measurement report, an antenna port precoder configuration to use for communicating with the UE.

Abstract: Methods, systems, and devices for wireless communication are described in which a number of reference signal processes may be configured for a number of slots in a radio frame, and a corresponding reference signal process for each slot may be based at least in part on a location of the slot within the radio frame and a number of configured reference signal processes. An indication may be provided to a user equipment (UE) in each slot that indicates a presence or absence of a reference signal transmission in the slot.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify a set of power configurations for a plurality of communications with at least one target device. The set of power configurations may be based at least in part on a type of signal, a type of channel, a parameter of the wireless device, a parameter of the target device, or a combination thereof. The wireless device may then determine a duplexing mode for the plurality of communications based at least in part on the set of power configurations. The duplexing mode may be, for example, a full duplex mode or a half-duplex mode. The wireless device may then transmit the plurality of communications to and/or receive the plurality of communications from the at least one target device according to the set of power configurations and the selected duplexing mode.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a discovery signal transmitted from a connection point (CP) via a directional beam. The discovery signal may include first information (including beam sweep configuration information) related to the CP. The apparatus then transmits an association signal to the CP based on the beam sweep configuration information and monitors for a resource grant from the CP based on the transmitted association signal. Alternatively, the apparatus transmits a discovery signal via a directional beam to a user equipment (UE). The discovery signal may include first information (including beam sweep configuration information) related to the apparatus. The apparatus then receives an association signal from the UE based on the beam sweep configuration information and determines a resource grant for communicating with the UE based on the received association signal.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for adjusting communication timings of beams (e.g., of beam pair links) within a beam timing advance group (TAG). In some cases, a base station may determine that transmission timing at a UE may be misaligned between multiple beams. The base station may configure a set of beams into a beam TAG, and may send a timing advance (TA) command for the beam TAG. A common timing reference value may be identified based on the TA command. UEs performing uplink transmissions may determine a TA value for the beam TAG based on the common timing reference value, and may adjust a communication timing for one or more of the beams within the beam TAG based at least in part on the common timing reference value and the timing advance value.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink transmission to a base station is to occur in accordance with an uplink timing advance value representing an amount of time that the uplink transmission takes from transmission at the UE to reception at the base station. The UE may perform an autonomous open-loop adjustment to the uplink timing advance value. The UE may transmit the uplink transmission to the base station in accordance with the adjusted uplink timing advance value. The base station may transmit an indication of a set of uplink timing advance values for a UE to use for uplink transmissions, each of the set of uplink timing advance values representing an amount of time that an uplink transmission is expected to take from transmission at the UE to reception at the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink message to a user equipment (UE). The base station may allocate a receive time window associated with receiving an uplink message from the UE responsive to the downlink message, wherein the receive time window is allocated based at least in part on a maximum propagation round trip time (RTT) associated with UEs within a coverage area of the base station and a frame size of the uplink message. The base station may monitor the receive time window for the uplink message from the UE. The base station may receive the uplink message from the UE during the receive time window.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may initiate handover from one base station to another. The handover procedure may not include random access channel (RACH) transmissions, and thus may be a localized RACH-less handover. The UE may initiate handover to a new base station based on the relative location of the UE and the new base station, some predetermined time, or based on the characteristics of the signals from each base station.
