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: A first apparatus may communicate with a user equipment through a first active beam. The first apparatus may determine that beam tracking is to be performed with the UE, including identifying a new beam for communication between the UE and the apparatus. The first apparatus may perform beam tracking with the UE based on the determination that beam tracking is to be performed. The first apparatus may communicate with the UE through a second active beam based on the beam tracking.

Abstract: Various aspects described herein relate to techniques for beam discovery and beamforming in wireless communications (e.g., 5th Generation (5G) New Radio (NR)). In an aspect, a method related to signaling for channel state information reference signals (CSI-RSs) in wireless communications is provided. The method includes receiving, by a user equipment (UE), a CSI-RS beam of a set of CSI-RS beams, and the CSI-RS beam includes a change indication message. The method further includes determining, by the UE, whether the set of CSI-RS beams have changed based on a value of the change indication message.

Abstract: Certain aspects of the present disclosure provide techniques for assisted power control for an uplink signal transmitted during a RACH procedure. A UE may determine a transmit power for transmitting a message during a RACH procedure with a secondary BS, based at least in part, on communication between the UE and a primary BS. The UE may transmit the message to the second BS during the RACH procedure based, at least in part, on the determined transmit power.

Abstract: In millimeter wave systems, user equipment may not be able to receive RACH parameters through a PDCCH when the information is transmitted with an omni-directional beam. In an aspect of the disclosure, an apparatus, such as a base station, may determine the RACH parameters and transmit a subset of the RACH parameters via a PBCH. The user equipment may receive the RACH parameter subset and initiate a RACH procedure.

Abstract: According to an aspect of the disclosure, a base station may convey the parameter information to the UE based on selection of particular resources to be used for transmission of synchronization signals, where the selected resources correspond to the particular parameter information. The UE may blindly detect the synchronization signals on various candidate resources and determine the parameter information based on the resources where the synchronization signals are detected. The apparatus may be a base station. In an aspect, the base station determines parameter information of one or more parameters. The base station selects, based on the parameter information, synchronization resources from a plurality of candidate resources for transmission of one or more synchronization signals, where the selected synchronization resources correspond to the parameter information. The base station transmits the one or more synchronization signals using the selected synchronization resources.
