Abstract: A UE may receive, from a base station, a configuration for a plurality of parameter sets that each include one or more parameters for a RACH message and are each associated with one of TDM, FDM, or SDM. The UE may determine a transmission type of the RACH message corresponding to one or more of the TDM, the FDM, or the SDM and transmit the RACH message to the base station based on at least one parameter set and the determined transmission type of the RACH message. In aspects, the configuration received by the UE may be a configuration for transmitting the RACH message based on a RACH determination protocol. The UE may transmit the RACH message to the base station based on the received configuration associated with the RACH determination protocol and the determined at least one transmission type of the RACH message.

Abstract: Method and apparatus to rewrite BAP headers in IAB networks. The apparatus receives, from a second base station, a routing configuration indicating a mapping between a first routing ID and a second routing ID. The apparatus receives a packet with a packet header indicating the first routing ID. The apparatus determines the second routing ID based on the routing configuration mapping the first routing ID in the packet header to the second routing ID. The apparatus modifies, based on a determination of the second routing ID, the packet header to replace the first routing ID with the second routing ID. The apparatus transmits the packet based on the second routing ID.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station central unit (CU) may transmit, and a second base station CU may receive, first inter-CU signaling including information related to cross-link interference (CLI) experienced by or to be measured by one or more victim downstream nodes associated with the first base station CU. The second base station CU may configure one or more aggressor downstream nodes to transmit one or more signals based at least in part on the first inter-CU signaling. The second base station CU may transmit, and the first base station CU may receive, second inter-CU signaling indicating a configuration associated with the signals to be transmitted by the one or more aggressor downstream nodes based at least in part on the first inter-CU signaling. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station distributed unit (DU) may identify, based at least in part on information associated with a second base station DU, one or more resources for crosslink interference (CLI) measurement for the second base station DU. The first base station DU may perform one or more CLI measurements for a cell associated with the second base station DU based at least in part on the one or more resources. Numerous other aspects are provided.

Abstract: A IAB-node is provided with two Distributed Units (DU). The first one depends from a first IAB - donor Central Unit and the second from a second Central Unit of a gNB base station. The interference in a cell served by the IAB-node and associated with the second DU is reduced by the IAB-node sending a first resource configuration of the cell to the IAB donor CU, the first resource comprising information allowing the IAB donor CU to generate a second resource configuration for the cell.

Abstract: Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a node or a base station. In one aspect, the apparatus may receive, via a first set of resources, communication including at least one data packet, the first set of resources allocated for a reception entity of the node. The apparatus may also decode, at the reception entity, the at least one data packet during a decoding period, the decoding period including a decoding start time and a decoding completion time. Additionally, the apparatus may transmit, via a second set of resources, the communication including the at least one data packet to a next hop node, the second set of resources allocated for a forwarding entity of the node, at least one first resource overlapping with at least one second resource.

Abstract: Aspects relate to reporting timing adjustment for full-duplex (FD) communications. A method by a user equipment (UE) may include receiving a first timing advance signal from a base station, determining, based on the first timing advance signal, a timing difference between a downlink signal and an uplink signal is not within a threshold, transmitting a timing report to the base station, including the determined timing difference, and receiving, from the base station, an updated timing advance signal for fullduplex (FD) communication based on the timing report.

Abstract: Aspects of the disclosure relate to a repeater in a wireless communication system. The repeater is configured to detect synchronization signals broadcast by one or more cells in the communication system, and then process at least one portion of the detected synchronization signals in the repeater. From the detected synchronization signals, the repeater determines at least one of a cell selection and a beam forming configuration for at least a fronthaul link between the repeater and a base station in the communication system based on the processing of the at least one portion of the detected synchronization signals. This allows the repeater to gain information for beam forming without the need for digital processing and to establish a control link with the base station or cell.
