[0004] The Ambient Internet of Things (AIoT), also known as the Ambient Power-Enabled Internet of Things (Ambient Power-Enabled IoT), is a type of IoT service. AIoT devices are low-power IoT devices that consume low power overall, including low-power signal reception and low-power signal transmission. Due to this low overall power consumption, communication energy can come from the environment, such as wind energy, kinetic energy, thermal energy, and radio frequency (RF) signals. AIoT devices can also be described as passive IoT devices or transponder devices.

[0005] In order to support the technology of Ambient Internet of Things (AIoT), it is necessary to use licensed spectrum: for example, terminals (User Equipment, UE), integrated access backhaul (Integrated Access Backhaul, IAB), relays, etc. as readers or intermediate devices of readers need to use the operator's licensed spectrum to communicate with AIoT devices. The licensed spectrum is usually configured and controlled by the Radio Access Network (RAN), but in the current related technologies, on the one hand, the access network equipment is not clear about which devices will communicate with the AIoT devices, and on the other hand, the readers or intermediate devices of the readers are not clear about where to obtain the wireless resource configuration, resulting in the inability to support communication with AIoT devices. Therefore, how to support communication with AIoT devices is an urgent problem to be solved. Summary of the Invention

[0118] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects, for example, the first object can be one or more. In addition, "or" in this application represents at least one of the connected objects. For example, "A or B" covers three options, namely, Option 1: including A but not including B; Option 2: including B but not including A; Option 3: including both A and B. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0119] The term "indication" in this application can be either a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.
