[0002] This application claims priority to Chinese Patent Application No. 202311784199.7, filed in China on December 22, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of wireless communication technology, specifically relating to a communication method, apparatus, communication device, and readable storage medium. Background Technology

[0004] Ambient Internet of Things (AIoT), also known as Ambient Power-enabled Internet of Things (AIoT), is a type of IoT service. AIoT devices are low-power IoT devices, characterized by low overall power consumption, including low-power signal reception and transmission. Due to their low overall power consumption, the energy for communication can be derived from the environment, such as wind power, kinetic energy, heat energy, and radio frequency (RF) signals. AIoT devices can also be described as passive IoT devices or responding devices.

[0005] To support Ambient Internet of Things (AIoT) technologies, licensed spectrum is required. For example, user equipment (UE), integrated access backhaul (IAB), and relays, acting as readers or intermediate devices, need to use licensed spectrum from operators to communicate with AIoT devices. Licensed spectrum is typically configured and controlled by the Radio Access Network (RAN). However, in current technologies, on the one hand, RAN devices are unaware of which devices will communicate with AIoT devices; on the other hand, readers or intermediate devices are unclear about where to obtain radio resource configurations, resulting in communication difficulties with AIoT devices. Therefore, how to support communication with AIoT devices is a pressing issue that needs to be addressed. Summary of the Invention

[0117] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0118] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, without limiting the number of objects; for example, the first object can be one or more. Furthermore, "or" in this application indicates at least one of the connected objects. For example, "A or B" covers three scenarios: Scenario 1: including A but not B; Scenario 2: including B but not A; Scenario 3: including both A and B. The character " / " generally indicates that the preceding and following objects are in an "or" relationship.

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

[0494] The third information also includes at least one of the following:

[0495] Information used to identify the reader / writer device;

[0496] Information used to identify the first communication device;

[0497] Information used to identify the AIoT task;

[0498] Information used to identify the second communication device.

[0499] Optionally, the first request includes at least one of the following:

[0500] Information used to identify the reader / writer device;

[0501] Information used to identify the AIoT task;

[0502] Information used to identify the second communication device;

[0503] or,

[0504] The second request includes at least one of the following:

[0505] Information used to identify the reader / writer device;

[0506] Information used to identify the AIoT task;

[0507] Information used to identify the second communication device.

[0508] In one implementation, different readers may use different intermediate devices, and different intermediate devices may be connected to different readers. It is easy to understand that the information used to identify the reader can help determine which reader the intermediate device belongs to.

[0509] In one implementation, different AIoT tasks may be executed by different devices, and different devices may execute different AIoT tasks. It is easy to understand that the information used to identify the AIoT task can help determine which AIoT task the second communication device is executing.

[0510] In one implementation, a reader may have multiple intermediate devices, and the second communication device identifier may be used to help distinguish different second communication devices.

[0511] Optionally, the information used to identify the reader includes: the identification information of the reader.

[0512] Optionally, the information used to identify the AIoT task includes: the identification information of the AIoT task.

[0513] Optionally, the information used to identify the second communication device includes: identification information of the second communication device.

[0514] Optionally, when the fourth communication device obtains the second request, the second request is used to indicate a request to use the second communication device as an intermediate device for the first communication device.

[0515] In one embodiment, the first communication device includes a reader / writer device, and the fourth communication device receives a first request from the first communication device, which may indicate that the first communication device requests the second communication device to act as an intermediary device for the first communication device. It is easy to understand that in this case, separate information for identifying the reader / writer is not required.

[0516] In another implementation, the fourth communication device receives a first request from the third communication device. If the first request is used to request the second communication device to act as an intermediary device for the first communication device, it is easy to understand that if the third communication device is different from the first communication device, information for identifying the first communication device (such as a reader / writer) is also required.

[0517] In another implementation, where the fourth communication device obtains a first request, and the first request is used to request the second communication device to act as the execution device for the AIoT task, it is easy to understand that information for identifying the AIoT task is also required.

[0518] In the embodiments of this application, the fourth communication device authorizes or activates the second communication device as at least one of the following: a reader / writer device, an intermediate device, a device communicating with an AIoT device, a device performing an AIoT task, an excitation source, or a carrier source; or, the fourth communication device sends first information to the first communication device to indicate that the second communication device is at least one of the following: a reader / writer device, an intermediate device, a device communicating with an AIoT device, a device performing an AIoT task, an excitation source, or a carrier source, so that the first communication device can perform an activation or authorization operation on the second communication device based on the first information. This solves the problem in related technologies where RAN devices cannot know the devices performing AIoT tasks, and helps to optimize the communication process in wireless communication networks.
