Abstract: Methods, systems, and devices for wireless communications are described. A child node may communicate in an integrated access and backhaul (IAB) communications system with a parent node and the parent node may transmit system information to the child node that may indicate one or more random access channel (RACH) procedure configurations such as a user equipment (UE)-specific RACH procedure configuration and a wireless backhaul-specific (e.g., IAB-specific) RACH procedure configuration. The child node may be configured to utilize the UE-specific RACH procedure configuration or the IAB-specific RACH procedure configuration such as if the child node meets one or more conditions or upon receiving an indication from the parent node. The child node may determine to use the UE-specific RACH procedure configuration for communicating with the parent node and may perform a RACH procedure with the parent node in accordance with the UE-specific RACH procedure configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information, the configuration information indicating that the UE may use one or more uplink grants for a sidelink communication. The UE may receive scheduling information indicating an uplink grant, of the one or more uplink grants, of uplink resources for an uplink communication of the UE. The UE may transmit, to another LIE and via a sidelink, the sidelink communication using the uplink resources. Numerous other aspects are described.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving, from a first transmission and reception point (TRP) operating in a first band, assistance information comprising collocation information for both a second TRP operating in a second band and a communication node operating in the first band. The method also includes receiving, from the first TRP, configuration information for one or more reference signals (RSs) associated with the communication node. The method further includes communicating with the second TRP based on one or more features of the second band estimated from the one or more RSs.

Abstract: The present disclosure provides systems, apparatuses, methods, and computer-readable media for event identification for beam failure reporting in a wireless communication system. A user equipment (UE) may detect a beam failure event associated with a downlink communication beam and may transmit a beam failure report (BFR) message associated with the beam failure event. The BFR message may include an event identifier (ID) associated with a time of the beam failure event. Alternatively, or in addition to the event ID, the BFR message may include one or more other features, such as an indication of a priority level associated with the BFR message. A network node may receive the BFR message and may transmit a response to the BFR message. The response may indicate one or more operations to be performed by the UE, such as a beam recovery operation to “recover” the downlink communication beam.

Abstract: Methods, systems, and devices for wireless communications are described. An energy harvesting device, such as a user equipment (UE) or a radio frequency identification (RFID) tag, may receive, from an energy transfer device such as a network node, an energy harvesting signal providing power for the energy harvesting device. The energy harvesting device may transmit, based on the energy harvesting signal, a control message indicating one or more parameters for a square waveform for energy harvesting, a requested duty cycle for the square waveform, or both. The energy harvesting device may receive the square waveform in response to the control message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first message activating a plurality of transmission configuration indicator (TCI) states for the UE for uplink communications. The UE may receive a second message that indicates, for uplink communications by the UE, a first TCI state of the plurality of TCI states and that indicates an activation of an uplink beam selection procedure for autonomous selection of an uplink beam by the UE, and may transmit an uplink message using a second TCI state different from the first TCI state, the second TCI state selected by the UE based on the uplink beam selection procedure. In some examples, the UE transmit a request for the activation of the uplink beam selection procedure by the UE.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a road-side unit (RSU) may join a first sidelink (SL) ranging session between a first user equipment (UE) and a second UE. The RSU may perform SL ranging with the first UE to determine first ranging information comprising at least a RTT to the first UE. The RSU may perform SL ranging with the second UE to determine second ranging information comprising at least a RTT to the second UE. The RSU may send the first ranging information and the second ranging information to at least one of the first UE or the second UE, or calculate a range between the first UE and the second UE based on the first ranging information and the second ranging information, and send the range to at least one of the first UE and the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. A receiver user equipment (UE) may communicate with a transmitter UE in a sidelink channel to report a congestion index to the transmitter UE and/or additional transmitter UEs, where the transmitter UE(s) may then adjust one or more sidelink operation parameters based on the reported congestion index. In some cases, the transmitter UE may report the congestion index to an upper layer, to other transmitter UEs, to application layers, or a combination thereof. The transmitter UEs 115 and/or application layer may then adjust one or more sidelink transmission operation parameters based on the reported congestion index. For example, the transmitter UEs and/or application layer may adjust threshold values to lessen a number of retransmissions and lessen congestion.
