Abstract: Techniques are provided for power control in directional beam environments. A user equipment (UE) may determine one or more power parameters on a beam-by-beam basis. Each directional uplink transmission beam in a communication link between the UE and the base station may be independently controlled using these beam-specific power parameters. Examples of these beam-specific power parameters may include a maximum output power for a given directional uplink transmission beam and a difference between the maximum output power for the given directional uplink transmission beam and an estimated transmit power for the given directional uplink transmission beam. The UE may report one or more of these beam-specific power parameters to a base station using a beam-specific report.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may utilize different beam configurations for different signal types, traffic demand, path loss, capabilities of the wireless device or other wireless devices in the system, and the like. The wireless device also may be capable of determining different duplexing modes, which may be utilized in addition to the different beam configurations. The duplexing mode may be based on received measurement reports (e.g., from one or more reference signals) or in some instances, the duplexing mode may be determined by another node (e.g., a core network node, a base station) and transmitted to the wireless device.

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 communications are described that support node connection techniques in wireless systems, such as relay node connections in a wireless backhaul network. A first node, which may be a new node or a node seeking to re-establish a connection, may initiate a connection establishment through transmission of a synchronization signal (SS). The first node, responsive to the SS transmission, may receive a response signal from one of the other nodes, and may establish a link with the other node. In some cases, the response signal may be an SS transmission from the other node, and the first node may transmit a random access request to the other node to initiate establishment of the link. In other cases, the response signal may be a random access request from the other node to initiate establishment of the link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first synchronization signal (SS) block that does not include remaining minimum system information (RMSI). The first SS block may indicate an offset for obtaining a second SS block that includes RMSI. The UE may determine a location of the second SS block based at least in part on the offset. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described for dynamically configuring a schedule and a set of transmission resources for delivering additional system information. A first type of system information, such as remaining minimum system information (RMSI), may include configuration information indicative of the dynamically-configured schedule and set of transmission resources for delivering the additional system information, such as other system information (OSI). The dynamically-configured set of transmission resources for delivering the additional system information may be a control resource set (CORESET), and control information within the CORESET may be encoded with a radio network temporary identifier that is the same as or different than the first set of system information.

Abstract: Wireless communication techniques that include beam training performed to aid mobile devices in identifying beams for use in communications (e.g., uplink communications) are discussed. A mobile device may transmit to a base station an indication of a level of beamforming reciprocity of the mobile device. A base station/gNB may transmit an indication of one or more transmission beams to be used by the mobile device for uplink wireless communication based on the level of beamforming reciprocity. The one or more transmission beams to be used by the mobile device for uplink communication may include a reciprocal transmission beam. A mobile device not capable of full beamforming reciprocity may determine a transmission beam through uplink beam training. A mobile device may transmit to a base station information using at least one of the one or more transmission beams. Other aspects and features are also claimed and discussed.

Abstract: Methods, systems, and devices for wireless communication are described. The method may include transmitting a first synchronization signal in a set of beam directions during a first symbol period of a synchronization subframe and transmitting a second synchronization signal in another set of beam directions during a second symbol period of the synchronization subframe. The second set of beam directions may be spatially interleaved with the first set of beam directions. Additionally, the method may include monitoring a first and second set of beam directions during a first and second symbol period of a random access subframe, respectively. Additionally, the method may include receiving, from a base station, first and second synchronization signals in a synchronization subframe, decoding the first synchronization signal, and transmitting an access request based at least in part on the decoded first synchronization signal.

Abstract: Methods, systems, and devices for wireless communication are described that provide for synchronization signal (SS) burst set patterns in which SSs and broadcast channel transmissions may be transmitted (e.g., in time). A base station may identify a SS burst set pattern indicating positions (e.g., time locations) for SS block transmissions, for example, in bandwidth restricted communication systems. The SS burst set pattern may be determined based on numerology or subcarrier spacing associated with SSs and non-SSs. The base station may transmit an indication of the SS burst set pattern to a wireless device. The wireless device may receive the indication of the SS burst set pattern and determine one or more time locations of SSs (e.g., primary synchronization signal (PSS), secondary synchronization signal (SSS), physical broadcast channel (PBCH) of a SS block). The wireless device may then monitor the identified positions for SSs.

Abstract: Aspects of the present disclosure provided techniques for wireless communications by a base station. An exemplary method generally includes transmitting, on a narrowband region within a wider system bandwidth, a directional primary synchronization signal (DPSS), receiving feedback information from one or more user equipments (UEs) based on the DPSS, wherein the feedback information comprises an indication of a bandwidth capability of a UE that transmitted the feedback information, and allocating resources to the one or more UEs within at least one of the wider system bandwidth or the narrowband region based, at least in part, on the feedback information.
