Abstract: A user equipment (UE) may transmit, to a primary cell, an indication of a capability to synchronize with a secondary cell based on measurements of the primary cell. A UE may estimate a propagation delay (tp) and an angle of arrival (AoA) of the secondary cell based on a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) transmitted by the primary cell. A UE may perform automatic gain control (AGC), fine timing synchronization, and fine frequency synchronization of the secondary cell based on a temporary aperiodic tracking reference signal (A-TRS) transmitted by the secondary cell. A UE may perform a receive beam sweep on a burst of a CSI-RS transmitted by the secondary cell, wherein a range of the receive beam sweep is based on the estimated AoA.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to an integrated access and backhaul (IAB) donor central unit (CU), information indicating a cell served by the network node and associated with another CU. The network node may receive, from the IAB donor CU, a distributed unit (DU) cell resource configuration for the cell. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. For example, a user equipment (UE) may receive a paging indication over a physical downlink control channel. The UE may determine a position of the UE relative to a network entity. The UE may determine, based on the position of the UE, a subset of beams available to the network entity for transmitting a paging message. The subset of beams may be less than a quantity of beams available to the network entity for transmitting the paging message and a coverage area of the subset of beams may include the position of the UE. The UE may monitor, based on receiving the paging indication, the subset of beams over a physical downlink shared channel for the paging message.

Abstract: Methods, systems, and devices for wireless communications are described. The network may manage access to a cell on a per-beam basis. The network may indicate, for a given beam, whether a user equipment (UE) is able to access the cell via the given beam. Accordingly, the UE may access a cell using a beam that is not barred for the UE. In some examples, control signaling may include a list of each beam associated with the cell and may indicate whether each beam is barred or accessible. In some examples, control signaling include a field indicating whether the particular beam on which the control signaling was transmitted is barred. In some examples, control signaling may indicate whether a cell is barred. The UE may interpret the indication of whether the cell is barred as indicating whether the beam on which the control signaling was transmitted is barred.

Abstract: An apparatus acquires random access information for at least one of a donor node serving the node or a neighbor cell of the node and determines one or more random access parameters for a device to perform a random procedure with the node. The one or more random access parameters are based on the acquired random access information. The apparatus may be an IAB node.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for performing a common channel sensing procedure for transmissions via a mobile termination (MT) role or via a distributed unit (DU) role of an integrated access and backhaul (IAB) node, or both. In one aspect, the IAB node may obtain channel access for transmissions via the MT role or the DU role, or both, using the same channel sensing procedure. The IAB node may select a timing of a sensing slot for the common channel sensing procedure in accordance with a capability of the IAB node and a timing of the transmissions. The IAB node may initiate a channel occupancy time (COT) for the transmissions via the MT role or the DU role, or both, as a result of determining that a measured energy detection (ED) value satisfies an ED threshold.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive mobility state information associated with an integrated access backhaul (IAB) node. The mobility state information may include information associated with at least one of: a level of mobility of the IAB node, or a change in mobility of the IAB node. The wireless communication device may perform an operation based at least in part on the mobility state information associated with the IAB node. In some aspects, a wireless communication device may determine that mobility state information associated with an IAB node is to be transmitted, and may transmit the mobility state information associated with the IAB node based at least in part on the determination. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a child node of a parent node in an integrated access backhaul (IAB) network may determine communication information that includes one or more of a schedule or a configuration for a communication to be transmitted by the child node. The child node may be an IAB node, and the parent node may be an IAB donor or an intervening IAB node between the IAB node and an IAB donor. The child node may transmit the communication information to the parent node via a wireless backhaul link between the child node and the parent node. Numerous other aspects are provided.
