    Abstract: A user equipment (UE) receives a first synchronization signal (SS) block including a first codeword and a second SS block including a second codeword. Each codeword is based at least in part on a linear encoding of a physical broadcast channel (PBCH) payload. The PBCH payloads include different timing indicators. The SS blocks are received at different times separated by a time increment. The UE determines, based at least in part on the time increment, one or more hypotheses of combined decoding metrics for the first codeword and the second codeword; decodes the first codeword based on each of at least one hypothesis in the one or more hypotheses. The at least one hypothesis includes a correct hypothesis; the UE determines the first codeword based at least in part on an error detection procedure such as CRC verification performed when decoding the first codeword based at least in part on the correct hypothesis.

    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. The apparatus receives from the base station a number of beams whose information should be fed back to the base station. 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.

    Abstract: Techniques are described for wireless communication. A method of wireless communication at a first wireless device includes identifying a template mapping of a plurality of ports to a first plurality of frequency subcarriers and a first plurality of time periods of a template time-frequency resource grid; mapping a plurality of resource elements of an orthogonal frequency-division multiplexing (OFDM) time-frequency resource grid to the plurality of ports based at least in part on the template mapping; receiving a reference signal from a second wireless device, on a subset of the plurality of ports, based at least in part on the mapping; and decoding the reference signal from a subset of the plurality of resource elements based at least in part on the mapping. In some cases, each port of the plurality of ports is associated with a corresponding radio frequency (RF) chain.

    Abstract: A UE may receive, from a base station, a message requesting BSI. The UE may determine a number N of BSI reports to send to the base station, and each BSI report may indicate a beam index corresponding to a beam and a received power associated with the beam. The UE may send, to the base station, N BSI reports based on the message requesting BSI. The UE may receive, from the base station, a set of signals through a set of beams, and determine the received power for each signal of the set of signals received through each beam of the set of beams, each received power may be associated with a beam of the set of beams.
