US Patent 10404343 Use of downlink beam tracking results in reference symbol sessions

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.
