Abstract: Methods, systems, and devices for wireless communications are described. In some systems, base stations and user equipment (UEs) may use beamforming for transmitting random access channel (RACH) messages. A UE may transmit multiple RACH preamble messages (e.g., within a random access response (RAR) window) to initiate a RACH procedure. The UE may transmit the RACH preamble messages in transmission opportunities corresponding to reference signals received from the base station. In some cases, the UE may determine the number of RACH preamble messages to transmit within the RAR window based on an ability of the UE to simultaneously monitor for a RAR message in response to each of the transmitted messages. In other cases, the UE may transmit an indication of UE capabilities to the base station. The base station may determine a RACH resource configuration for the UE based on the capabilities and may indicate the configuration to the UE.

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: 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: Wireless communications systems and methods related to communicating in an integrated access backhaul (IAB) network are provided. A first wireless communication device receives synchronization information associated with one or more wireless relay devices. The first wireless communication device adjusts one or more synchronization references of the first wireless communication device based on at least a subset of the received synchronization information. The first wireless communication device communicates, with the one or more wireless relay devices, communication signals in synchronization with the one or more adjusted synchronization references, wherein at least one of the communication signals includes backhaul data.

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: Aspects of the present disclosure provide for beam management in wireless communication systems. In some examples, beam angle information (e.g., angles of arrival/departure) may be utilized to select one or more serving downlink beams for communication between a scheduling entity and a scheduled entity. The beam angle information may further be utilized to facilitate additional operations within a backhaul network, such as wireless node locating, obstacle locating, system mapping within the network topology, beam determination and beam sweeping configuration, and mobility management among wireless nodes of a backhaul network. In other examples, aperiodic uplink beam measurements may be triggered based on downlink beam measurement reports and/or in response to a request from a scheduled entity. The scheduling entity may then jointly select uplink and downlink beams based on both the received downlink beam measurement report and uplink beam measurements.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify resources associated with a beamformed signal, the identified resources being used by a user equipment (UE) for channel measurements of the beamformed signal, the beamformed signal being one of a plurality of beamformed signals. The base station may generate a signal indicating at least a portion of the identified resources and transmit the signal to the UE. The UE may receive the signal and perform a channel measurement of the beamformed signal using the indicated resources. The UE may transmit, to the base station, a measurement report comprising the channel measurement associated with the beamformed signal.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit, to a user equipment (UE) operating in a discontinuous reception mode, a wakeup signal indicating whether data is available to be transmitted to the UE, the wakeup signal transmitted using a first set of transmit beams, which may be selected from a periodic beam management procedure, in accordance with a beam sweeping configuration. The base station may receive, from the UE and based at least in part on the wakeup signal, a response signal. The base station may perform, based at least in part on the response signal, further beam update procedures to identify a second set of transmit beams for future transmissions of the wakeup signal and/or for transmission of physical downlink control channel (PDCCH) to the UE.

Abstract: A user equipment (UE) may initiate a random access (RACH) procedure using an uplink resource selected based on a corresponding received synchronization signal block. The UE may detect a random access procedure trigger. The UE may configure a selection threshold time. The selection threshold time may be based at least in part on a latency requirement of the UE. The UE may select a synchronization signal block having a corresponding uplink resource within the selection threshold time. The synchronization signal block and corresponding uplink resource satisfy one or more parameters or conditions. The UE may transmit a random access preamble on the corresponding uplink resource.
