Patent number: 12256375Abstract: In certain aspects, the disclosure is directed to a user equipment (UE) configured for wireless communications with a network node. The UE may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the UE may transmit, to a network node, an indication of an expected communication.

Publication number: 20240422588Abstract: A method of wireless communication by an integrated access and backhaul network (IAB) donor transmits a configuration message on a source path to a first IAB node via a first distributed unit of the IAB donor. The method also instructs the first IAB node to delay delivery of the configuration message to a second node.

Another method of wireless communication is executed by a first integrated access and backhaul network (IAB) node. The method receives a first configuration message over a source path to a first IAB donor via a first distributed unit of the first IAB donor. The method also delays delivery of the first configuration message to a second node until a trigger occurs.Type: ApplicationFiled: August 30, 2024Publication date: December 19, 2024Inventors: Naeem AKL, Karl Georg HAMPEL, Ozcan OZTURK, Navid ABEDINI, Jianghong LUO, Luca BLESSENT, Junyi LI, Tao LUO
