Abstract: When a first node is subject to a maximum permissible exposure (MPE) condition, it may be beneficial for the first node to signal, to a second node, an uplink beam to be used for communications and/or one or more properties of the uplink beam. For example, the first node may signal a downlink beam, from a first reciprocal beam pair, and an uplink beam, from a second reciprocal beam pair, to be used for communications, and/or may signal one or more properties of the uplink beam and/or the downlink beam. Additionally, or alternatively, the second node may transmit, to the first node, a signaling state (e.g., a transmission configuration indication (TCI) state) that indicates properties to be used to configure an uplink beam and/or a downlink beam. In this way, the first node and the second node may configure beams in a manner that accounts for MPE limitations.

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: Methods, systems, and devices are described for directional synchronization signal signals in a millimeter wave communication system. A user equipment (UE) may receive a narrowband signal component of a synchronization signal for the millimeter wave communications. The narrowband signal component may include correlation information. The UE may use the correlation information to identify a wideband signal component of the synchronization signal for the millimeter wave communications. The UE may search frequencies associated with a first frequency location determined from the correlation information to identify and detect the wideband signal component of the synchronization signal.

Abstract: Antenna ports on wireless devices may be QCL. QCL antenna ports may be useful in improving channel statistics related to the antenna ports. UEs and base stations may be able to determine candidate QCL ports, transmit information identifying the candidate QCL ports, and receive feedback indicating whether the candidate QCL ports are QCL at the receiving device such as a UE or a base station.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating with a base station via beamformed transmissions on an active beam. The UE may receive from the base station refined reference signals (RRSs) that include an active beam RRS corresponding to the active beam. The UE may identify that the active beam RRS corresponds to the active beam and perform a beam state measurement on the active beam RRS. The UE may refine the active beam based at least in part on the beam state information of the active beam RRS.

Abstract: A first apparatus may transmit, to a user equipment (UE), on a control channel, one or more indications of one or more beam indexes corresponding to one or more beams. The first apparatus may transmit, to the UE, one or more reference signals through the one or more beams corresponding to the one or more beam indexes. The reference signals may be used by the UE to select a best subarray and/or receive combiner for communication with the first apparatus.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for limiting UE capability information reported in a network. For example, a method of wireless communications by a first base station may include transmitting a first set of initial access signals in different directions, receiving a second set of one or more signals from a user equipment (UE) in response to the first set of initial access signals, and initiating transmission of, or conveying configuration of, a third set of reference signals with an indication of their corresponding directions, based on reception of the second set 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.
