Description

Technical Field

[0001] This application belongs to the field of wireless communication technologies, and particularly relates to a communication method, apparatus, communication device, and readable storage medium. Background Art

[0002] Ambient Internet of Things (AIoT), also known as Ambient power-enabled Internet of Things (Ambient power-enabled IoT), is an IoT service. An AIoT device is a low-power IoT device with relatively low overall power consumption, including low-power signal reception and low-power signal transmission. Since the overall power consumption is low, the communication energy can be sourced from the environment, such as wind energy, kinetic energy, thermal energy, radio frequency (RF) signals, etc. An AIoT device can also be described as a passive IoT device or a responder device.

[0003] To support the technology of Ambient Internet of Things (AIoT), licensed spectrum is required: for example, User Equipment (UE), Integrated Access Backhaul (IAB), relay, etc., as reader-writers or intermediate devices of reader-writers 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. However, in the current related technologies, on the one hand, the access network device does not know which devices will communicate with the AIoT device, and on the other hand, the reader-writer or the intermediate device of the reader-writer does not know where to obtain the wireless resource configuration, resulting in the inability to support communication with the AIoT device. Therefore, how to support communication with AIoT devices is an urgent problem to be solved. Summary of the Invention

[0115] Next, the technical solutions in the embodiments of the present application will be clearly described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0116] The terms "first", "second", etc. in this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of this 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 category, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "or" in this application means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, Scenario 1: including A and not including B; Scenario 2: including B and not including A; Scenario 3: including both A and B. The character " / " generally indicates an "or" relationship between the associated objects before and after.

[0117] The term "indication" in this application can be either a direct indication (or an explicit indication) or an indirect indication (or an implicit indication). Among them, a direct indication can be understood as that the sender clearly informs the receiver of specific information, operations to be performed, request results, etc. in the sent indication; an indirect indication can be understood as that the receiver determines the corresponding information according to the indication sent by the sender, or makes a judgment and determines the operations to be performed or request results, etc. according to the judgment result.

[0118] It is worth pointing out that the technology described in the embodiments of this application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, and can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in the embodiments of this application are often used interchangeably, and the described technology can be used not only in the systems and radio technologies mentioned above, but also in other systems and radio technologies. The following description describes the New Radio (NR) system for example purposes, and uses NR terms in most of the following descriptions, but these technologies can also be applied to systems other than the NR system, such as the 6th generation (6 thGeneration, 6G) communication system.

[0119] Question 1: To support the technologies of AIoT, licensed spectrum needs to be used. In typology 2 or 3, devices such as UEs and IABs need to use the operator's licensed spectrum to communicate with AIoT devices.

[0120] Generally speaking, RAN devices are required to allocate licensed spectrum, but the RAN devices do not know that the intermediate nodes (Intermedia note, also known as intermediate devices) have been authorized to perform communication with AIoT, which is one of the problems that need to be solved urgently at present. Among them, the intermediate device is a device for communication between the AIoT device and the RAN, and the intermediate device may be a UE, an IAB, a relay, etc.

[0121] Question 2: Whether the licensed spectrum supported by AIoT devices may be different also requires the configuration of the NG RAN, which is also one of the problems that need to be solved at present.
