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: Certain aspects of the present disclosure provide techniques for coordinated transmissions in certain systems, such as millimeter wave (mmW) systems. A method of wireless communication by a user equipment (UE) generally includes providing an indication to a plurality of base stations (BSs) of one or more selected beams for transmission by each of the plurality of BSs. The method includes determining one or more co-phase factors. The method includes receiving a coordinated transmission from the plurality of BSs based on the one or more selected beams and the one or more co-phase factors. A method by a BS generally includes receiving the indication from the UE of the one or more selected beam, determining one or more co-phase correction factors, and sending a coordinated transmission to the UE based, at least in part, on the one or more selected beam and the one or more co-phase correction factors.

Abstract: Wireless communications systems and methods related to mitigating maximum permissible exposure (MPE) constraints based on user equipment (UE) feedback are provided. A first wireless communication device transmits, to a second wireless communication device, a plurality of reports, each report indicating an allowable transmission power level at the first wireless communication device satisfying an MPE parameter. The first wireless communication device receives, from the second wireless communication device, a first configuration based on an MPE profile associated with the first wireless communication device in response to the plurality of reports. The first wireless communication device transmits, to the second wireless communication device, a first communication signal over a first beam based on the first configuration.

Abstract: Certain aspects of the present disclosure provide techniques for signaling information regarding beams used for data and control transmissions to a UE. For example, a method for wireless communications by a user equipment (UE), may generally include signaling information to a base station (BS) that the UE is seeking recovery of a beamformed link between the BS and the UE, and participating in recovery of the beamformed link in accordance with the information. A method for wireless communications by a base station (BS), may generally include receiving information from a user equipment (UE) that the UE is seeking recovery of a beamformed link between the BS and the UE, and participating in recovery of the beamformed link in accordance with the information.
