    Abstract: Methods, systems, and devices for wireless communications are described that provide for mesh connectivity between integrated access and backhaul (IAB) nodes. A first node of an IAB network may determine a routing address for a second node, and communications may be transmitted to the second node based on the routing address to allow for coordination between the first and second nodes. The first node may detect a discovery signal of a second node, and may determine to communicate with the second node based on the discovery signal. The first node may obtain the routing address based on one or more of transmitting a request for the routing address to a third node, establishing a sidelink connection with the second node to obtain the routing address, receiving a mapping between routing addresses and cell IDs that are transmitted in discovery signals, or any combinations thereof.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine to operate in accordance with an energy saving mode in which the base station only transmits remaining minimum system information (RMSI) on-demand or reduces transmission of RMSI with respect to when the base station is operating outside of the energy saving mode. A user equipment (UE) may detect the base station that is operating in an energy saving mode. The UE may transmit a request for the base station to transmit the RMSI to the UE, where the UE may transmit the request to the energy saving base station or to a serving base station of the UE. The UE may receive, from the base station operating in the energy saving mode and responsive to the request, a message including the remaining minimum system information.

    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.
