Abstract: A UE may receive a beam modification command that indicates a set of transmit beam indexes corresponding to a set of transmit beams of a base station, and each transmit beam index of the set of transmit beam indexes may indicate at least a transmit direction for transmitting a transmit beam by the base station. The UE may determine a set of receive beam indexes corresponding to receive beams of the UE based on the set of transmit beam indexes, and each receive beam index of the set of receive beam indexes may indicate at least a receive direction for receiving a receive beam by the UE. The UE may receive, from the base station, a signal through at least one receive beam corresponding to at least one receive beam index included in the set of receive beam indexes.

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. Synchronization signals may be transmitted using a set of phase offsets over different component carriers or using a single component carrier for each antenna port. For example, a base station may identify a set of synchronization signals (e.g., a set of primary synchronization signals (PSSs)) to be transmitted over one or multiple component carriers. In some cases, each PSS may be associated with a different component carrier, and the base station may apply a different phase offset to each PSS when transmitting the set of PSSs on the component carriers. In some examples, the base station may transmit the PSSs on the component carriers using a different antenna port for each component carrier.

Abstract: A user equipment (UE) may be configured to perform a random access channel (RACH) procedure with a base station. As part of the RACH procedure, the base station may transmit a contention resolution message to the UE. The UE may receive, from the base station, the contention resolution message. The contention resolution message may indicate at least a beam index corresponding to a beam, such as a transmit beam of the base station. The UE may determine whether the beam index is applicable to the UE. The UE may communicate with the base station through the beam corresponding to the beam index when the beam index is applicable to the UE. For example, the UE may send an acknowledgement message to the base station, and the base station and UE may switch to a beam corresponding to the beam index after communication of the acknowledgement message.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for adjusting timing advance command parameters for specific beam pair links (BPLs) in a wireless communications system. In some cases, a base station may determine that transmission timing at a UE may be misaligned. The may send a timing advance (TA) command for the BPL. A UE may utilize more than one BPL, and may switch communications from a first BPL to second BPL. The second BPL may have a different timing misalignment than the first BPL, and the TA command sent by the base station may be insufficient to correct the timing misalignment of the second BPL. The base station may adjust the TA command parameters (e.g., TA command size or TA command granularity) so that the timing misalignment of the second BPL may be corrected.

Abstract: Methods, systems, and devices for wireless communication are described that provide for establishment of communication links between nodes in a wireless network, in which an access node (e.g., a node that provides access to a core network) may provide a communication link configuration and resources for communications between multiple nodes. In some cases, an access node may receive a request from a first node to establish a communication link with a second node. The communication link may be, for example, a directional transmission beam that carries data or control information, or a combination thereof, between the first node and the second node. The access node may determine the communication link configuration based on one or more link measurements provided by the first node or second node, and provide the configuration information to one or both of the first node or the second node.

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: 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: 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.
