Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit reference signals via a first antenna array of the first wireless device. The first wireless device may perform, according to a reporting configuration for self-interference at the first wireless device, a set of measurements on the reference signals received at a second antenna array of the first wireless device. The first wireless device may determine a priority associated with transmission of measurement reports associated with self-interference at the first wireless device. The first wireless device may then transmit, to a second wireless device and according to the reporting configuration, a measurement report including an indication of self-interference for full-duplex communications at the first wireless device that is based on performing the set of measurements on the reference signals, where the measurement report is transmitted in accordance with the determined priority.

Abstract: Methods, systems, and devices for wireless communications are described to coordinate information across a wireless network. One or more access nodes of a wireless network may configure a time resource container for receiving, amplifying, and forwarding a signal, such as a notification signal, in an operating mode. A notification signal may include an indication of coordination information and may be transmitted or received in the time resource container, such as in a first subset of a set of time resources of the time resource container. An access node may first receive a signal from a second access node, amplify and forward the signal in the time resource container to a third access node, and then decode the received signal and determine whether the signal includes coordination information for the access node. If the signal includes coordination information for the access node, the access node may perform one or more actions.

Abstract: In an embodiment, a UE establishes, with a peer sidelink UE, at least one sidelink communications link that each comprises one or more hops. The UE determines estimates a propagation delay between the UE and the peer sidelink UE based in part upon a relationship between a propagation time, between the UE and the peer sidelink UE, and Reference Signal Received Power (RSRP) irrespective of whether the UE remains synchronized with respect to the network clock.

Abstract: Methods, systems, and devices for wireless communications are described that provide for hop-count indication in an integrated access and backhaul (IAB) network. An IAB-node may adopt and indicate multiple values for hop-count. The hop-count may be conveyed by a number of different reference signals and channels. A resource pattern and/or a slot pattern may also be associated with the hop-count to simply signaling. By associating the patterns with the hop-count, an IAB-node may be able to infer the resource pattern used by another IAB-node.

Abstract: The present disclosure relates to methods and apparatus for wireless communication of a phased array repeater. The apparatus may receive, from a base station, a signal for a user equipment (UE) at a first frequency. The apparatus may also adjust, at the phased array repeater, the first frequency of the signal to a second frequency, where the first frequency may be adjusted by heterodyning. Additionally, the apparatus may transmit the signal to the UE at the second frequency. The present disclosure also relates to methods and apparatus for wireless communication. The apparatus may transmit a signal for a UE at a first frequency. Further, the apparatus may determine control information for tuning a frequency adjustment of the signal at a repeater. The apparatus may also transmit, to the repeater, the control information for tuning the frequency adjustment.

Abstract: Techniques are described for performing beam sweep procedures as part of a device discovery procedure. A communication device may receive a discovery preamble as part of a device discovery procedure. The discovery preamble may include information indicating that a discovery message will be transmitted. The communication device may determine whether to monitor for the discovery message of the device discovery procedure based at least in part on receiving the discovery preamble. The communication device may monitor for the discovery message based at least in part on the determination.

Abstract: Techniques are described for wireless communication. One method includes exchanging one or more signals between a first wireless node and a second wireless node, determining, at the first wireless node and based on the one or more signals, a range of correspondence between at least one of a transmit beam of the first wireless node and a receive beam of the first wireless node, determining a difference between indices of the transmit beam of the first wireless node and the receive beam of the first wireless node, and determining an uncertainty region for beam mapping based on the determined difference.

Abstract: The described techniques relate to improved methods, systems, devices, and apparatuses that support modem control using millimeter wave (mmW) energy measurement. Generally, the described techniques provide for wireless device (e.g., wireless repeater) power savings in the absence of an attached (e.g., connected) user equipment (UE). For example, a wireless repeater may perform relay operations (e.g., amplification and forwarding operations) for communications between a base station and a UE in some channel (e.g., in a mmW channel). The wireless repeater may use energy measurements in the channel (e.g., analog mmW measurements) to control or configure a digital interface for monitoring out of band control information (e.g., in a sub-6 gigahertz (GHz) channel). For example, a wireless repeater may use energy measurements of signals transmitted by devices in a mmW band to configure (e.g., turn on) a digital interface of another modem to monitor for control information in a sub-6 GHz band.

Abstract: Certain aspects of the present disclosure provide techniques for beam pair selection. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), an indication to report one or more beam pairs to be used for full-duplex (FD) communication based on a timing constraint, wherein the timing constraint comprises a constraint on a time difference between receptions, at the UE, of a downlink (DL) signal and an uplink (UL) signal for each of the one or more beam pairs and transmitting a report specifying the one or more beam pairs in accordance with the indication, in accordance with aspects of the present disclosure.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for transmitting a first random-access channel (RACH) message and receiving a second RACH message that includes a timing advance command (TAC) in a physical downlink control channel (PDCCH). These techniques may be used by a user equipment (UE) or an integrated access backhaul (IAB) node to achieve time synchronization while limiting overhead. In one example, in an IAB network, an IAB node may transmit a first RACH message to a neighbor node, and the IAB node may receive a TAC in a PDCCH of a second RACH message from the neighbor node. In another example, in a beam failure recovery (BFR) procedure, a UE may transmit a first RACH message to a base station, and the UE may receive a TAC in a PDCCH of a second RACH message from the base station.
