Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a downlink (DL) signal from a base station on one or more DL beam(s). The UE may identify a selected DL beam of the one or more DL beam(s) for communications from the base station to the UE. The UE may transmit a scheduling request message to the base station using at least one of a resource or a waveform selected based at least in part on the selected DL beam.

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: 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: The use of a radio access technology (RAT) may enable wireless communication using one or more node functions at a wireless node, such as a base station or access node. Additionally, multiple wireless nodes may communicate in a network using a schedule that is aligned with a frame structure. For example, a wireless node may establish a link with different wireless nodes using a RAT that supports a synchronized frame structure, such as a millimeter wave (mmW) RAT. The wireless nodes may instantiate one or more node functions, such as an access node function (ANF) and a user equipment function (UEF). The wireless nodes may then communicate according to active and suspended modes using the node functions, where the communication is based on a schedule aligned with the frame structure.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a number of beam directions that satisfy a transmission power condition. The UE may select a beam direction for a random access signal by choosing one of the beam directions that satisfies additional criteria, such as transmitting a random access message at the next opportunity. The transmission power may be selected based on a target receive power and a path loss for the selected beam. In some cases, if the sum of the path loss for a beam direction and the target receive power exceeds a maximum transmission power by more than a predetermined amount, the random access signal will not be transmitted using that beam. In some cases, if a response to the random access is not received, a different beam direction may be selected, the transmission power may be increased, or both.

Abstract: Methods, systems, and devices for wireless communication are described. Methods, systems, and devices provide for different tone spacing schemes for different channels. Methods, systems, and devices also provide for different tone spacing schemes for different stages of communication between a UE and a base station. The base station may indicate, to the UE, the tone spacing scheme in a control channel, a synchronization signal, or a reference signal and the tone spacing scheme may be selected by the base station from available tone spacing schemes for communication. Tone spacing schemes may also be referred to as numerologies.

Abstract: DM-RS symbols may be inserted in the beginning of a subframe, or in two parts of the subframe. In one aspect, a method, a computer-readable medium, and an apparatus for dynamically conveying DM-RS information are provided. The apparatus may be a base station. The apparatus may determine the number of DM-RS symbols and/or the locations within a subframe for transmission of the DM-RS symbols. The apparatus may transmit the number of the DM-RS symbols and/or the locations within the subframe for transmission of the DM-RS symbols to a UE. In another aspect, a UE may receive the number of DM-RS symbols and/or the locations within a subframe for transmission of the DM-RS symbols from a base station. The UE may decode the DM-RS symbols from the subframe based on the number of the DM-RS symbols and/or the locations within a subframe for transmission of the DM-RS symbols.

Abstract: In a mmW network, a UE and a base station may establish a link using a RACH procedure. Because mmW and other band communications may rely on accurate beamforming to overcome link attention, the UE may need to provide beam information feedback to the base station. In particular, the UE may receive a beam-formed message from the base station during the RACH procedure. The UE may determine beam information based on the received beam-formed message during the RACH procedure. The UE may transmit a message to the base station during the RACH procedure, and the message may include the determined beam information.
