    Abstract: When moving within an area covered by an Integrated access and backhaul (IAB) network, a mobile IAB node may come into proximity with another stationary or mobile IAB node that may have a same physical cell identifier (PCI) as the mobile IAB node. PCI collision issue may occur. Aspects presented herein address the possible PCI collisions. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an IAB node configured to determine a configuration associated with PCI management of a PCI of the IAB node. The apparatus may be further configured to change the PCI of the IAB node based on the determined configuration.

    Abstract: Methods, systems, and devices for wireless communications are described. For example, a first communication device may receive, from a second communication device, control signaling triggering a channel access procedure at the first communication device. In some case, the channel access procedure may be for accessing the shared radio frequency spectrum. The first communication device may then perform the channel access procedure based on the control signaling. In some examples, the first communication device may, based on the channel access procedure, transmit an indication of a channel occupancy initiated by the first communication device to the second communication device. The first communication device may relay communications between the second communication device and a third communication device during a channel occupancy time (COT) based on the transmitted indication of the channel occupancy initiated by the first communication device.

    Abstract: Methods, systems, and devices for wireless communication are described that provide for synchronization signal (SS) blocks in which synchronization signals and broadcast channel transmissions may be transmitted. Broadcast channel transmissions may be demodulated using SS transmissions, reference signal transmissions, or combinations thereof. Broadcast channel transmissions may be transmitted in a subset of SS block time resources, and synchronization signals may be transmitted in another subset of SS block time resources. Reference signals may be transmitted using tones within the broadcast channel time resources, and may be transmitted at a higher density for portions of the broadcast channel transmission bandwidth that are outside of the SS transmission bandwidth. Waveforms for reference signal transmissions, and information provided by reference signal transmissions may be provided.

    Abstract: Methods, systems, and devices for wireless communications are described. A first wireless node may transmit, to a control node, an indication of a capability of the first wireless node to perform one or more self-interference cancelation (SIC) procedures between a first antenna array of the first wireless node and a second antenna array of the first wireless node. The first wireless node may receive, from the control node in response to the indication of the capability, a configuration for the first wireless node to use to perform a SIC procedure of the one or more SIC procedures for full-duplex communications. The first wireless node may then communicate, according to the received configuration, with the control node, a control node, or any combination thereof, using the first antenna array and the second antenna array.

    Abstract: An assisting network device receives an incoming signal from a transmitting device. The assisting network device forwards the incoming signal to a receiving device in a beam direction based on a frequency of the incoming signal. A method of wireless communication by a first wireless device includes determining an indication of a frequency domain beam sweeping configuration of an assisting network device. The method communicates a signal with a second wireless device via the assisting network device in a beam direction based on a frequency of the signal. A method of wireless communication by a controlling entity determines a frequency domain beam sweeping configuration of an assisting network device. The method indicates the frequency domain beam sweeping configuration to a first wireless device, via the assisting network device, for communication with a second wireless device in a beam direction based on a frequency of an incoming signal.

    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for first integrated access and backhaul (IAB) node establishing a signaling connection with an IAB donor node and a sidelink connection with a second IAB node or a user equipment (UE). The first IAB node may include a mobile termination unit and a distributed unit and may support sidelink communications. In some cases, the first IAB node may report an indication of sidelink communications support, receive an indication of sidelink communication authorization, and receive sidelink configuration information. The first IAB node may transmit one or more data messages to the IAB donor on the signaling connection and transmit one or more data messages to the second IAB node or the UE via the sidelink connection.
