Technical Field

The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, and a storage medium for scheduling carriers in a symbiotic network.

Background

With the development of Internet of Things (IoT), the number of IoT devices is also increasing rapidly, which presents a great challenge to wireless spectrum and infrastructure network devices, and a symbiotic network (symb etic network) can solve the demand of wireless spectrum and infrastructure network devices. The symbiotic network is a wireless communication network in which an active communication system and a passive communication system coexist. As shown in fig. 1, a schematic diagram of a symbiotic network is exemplarily shown. The active communication system may be a conventional wireless communication system (e.g., 4th Generation mobile communication technology, 4G)/5G and wireless fidelity (WiFi)), and the passive communication system is an environmental backscattering communication (AmBC) system, and the passive communication system performs data transmission by backscattering radio frequency signals of the active communication system without an active radio frequency chain, so that a dedicated spectrum and an infrastructure may not be needed.

The symbiotic network in which the active communication system is a cellular communication system is called a symbiotic network based on cellular communication, that is, terminal equipment in the AmBC communication system communicates through backscattering cellular signals. In the symbiotic network, in order to improve the AmBC communication quality and reduce the interference of the AmBC communication to a cellular system, an AmBC resource pool is configured for a cell, and AmBC carrier scheduling is required to ensure that AmBC carriers are transmitted on the AmBC resource pool. However, there is no related scheme for performing AmBC carrier scheduling.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.

Hereinafter, some terms in the present application are explained to facilitate understanding by those skilled in the art.

1) The active communication system refers to a conventional wireless communication system, such as 4G/5G, wi-Fi. The communication device in the active communication system can transmit data by transmitting radio frequency signals by itself.

2) The passive communication system refers to an AmBC system. The communication device in such a communication system does not transmit radio frequency signals by itself, but transmits data by backscattering (backscatter) radio frequency signals of an active communication system.

3) The AmBC transmitter can realize the absorption or the back scattering of radio frequency signals (such as cellular signals) in the environment by the antenna through adjusting the impedance of the antenna, thereby realizing the transmission of '0' or '1'. For example, when the impedance is matched (e.g., the impedance is within a certain preset range), the antenna almost completely absorbs the radio frequency signal in the environment (also referred to as an absorption state), and then "0" is transmitted; when the impedance is not matched (for example, the impedance is not in a preset range), the antenna almost completely reflects the radio frequency signal in the environment (also referred to as a reflection state), and then "1" is transmitted. It can also be understood that the AmBC transmitter loads its own signal (low frequency signal) onto a radio frequency signal (high frequency signal) in the environment to enable the transmission of data.

4) The AmBC receiver performs sliding window averaging on the received signals to extract AmBC signals (low-frequency signals). It can also be understood that the high frequency signal in the received signal is filtered out to obtain the low frequency signal of itself.

5) AmBC carrier refers to cellular signals backscattered during AmBC communication. The method mainly comprises four types: a Downlink (DL) signal, an Uplink (UL) signal, a DL excitation carrier, and an UL excitation carrier.

The embodiments of the present application are not limited.

The terminal device may communicate with a core network via a Radio Access Network (RAN), exchanging voice and/or data with the RAN.

A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device has full functions and large size, and can realize complete or partial functions without depending on a smart phone, for example: smart watches or smart glasses and the like, and only focus on a certain type of application function, and need to be matched with other equipment such as a smart phone for use, such as various smart bracelets, smart helmets, smart jewelry and the like for physical sign monitoring.

The system can also be deployed on the water surface, or can also be deployed on airplanes, balloons and satellites in the air, which is not limited in the application.

In the present application, the terminal device has the transmitting capability of the uplink carrier. Specifically, the method may include three types of terminal devices, where a first type of terminal device has cellular communication capability (or other communication capability in an active communication system) and uplink excitation carrier transmission capability, a second type of terminal device has cellular communication capability (or other communication capability in an active communication system), uplink excitation carrier transmission capability and AmBC communication capability, and a third type of terminal device has AmBC communication capability. Wherein the terminal devices of the first type and the terminal devices of the second type may also be referred to as cellular terminal devices. The terminal devices of the second type and the third type may also be referred to as AmBC terminal devices.

Based on the above, as shown in fig. 2, a system architecture diagram of a symbiotic network based on cellular communication is exemplarily shown. The system may include a network device and a terminal device. The terminal devices may include a first type of terminal device, a second type of terminal device, and a third type of terminal device. The first type of terminal equipment has cellular communication capability and uplink excitation carrier transmission capability, the second type of terminal equipment has cellular communication capability, uplink excitation carrier transmission capability and AmBC communication capability, and the third type of terminal equipment has AmBC communication capability.

In combination with the system architecture, in order to ensure normal AmBC communication, the network device needs to perform AmBC carrier scheduling. Fig. 3 is a schematic diagram illustrating a scheduling principle of an AmBC carrier scheduler in a network device according to the present invention. The inputs to the AmBC carrier scheduler include: cellular communication related information (e.g., cellular transmission demand, cellular channel quality, etc.), amBC communication related information (e.g., measurement information of the AmBC resource pool, capability information of the terminal device, location information of the terminal device, etc.), and so on. The outputs of the AmBC carrier scheduler include: the type of the AmBC carrier (e.g., a conventional DL signal, a conventional UL signal, a DL excitation carrier, or a UL excitation carrier), terminal devices associated with the AmBC carrier (e.g., a terminal device for receiving a conventional DL signal, a terminal device for transmitting a conventional UL signal, and a terminal device for transmitting a UL excitation carrier), time-frequency resources where the AmBC carrier is located, and the like.

The following describes in detail how the network device performs AmBC carrier scheduling with reference to the accompanying drawings.

Fig. 4 is a schematic flowchart of a scheduling method for carriers in a symbiotic network according to the present application. In the following description, the method is applied to the network architecture shown in any one of fig. 1 or fig. 2 as an example. The method comprises the following steps:

step 401, the terminal device determines the AmBC capability information and the measurement information of the AmBC resource pool.

Here, the AmBC capability information may include UL excitation carrier transmission capability. That is, the terminal device can report to the network device whether it has UL excitation carrier transmission capability. The specific form of reporting the UL excitation carrier transmission capability by the terminal device may be predetermined by the terminal device and the network device, or predefined by a protocol, which is not limited in this application. For example, the UL excitation carrier transmission capability of the terminal device may be represented by one or more bits of information, which may be identified by 1bit, "0" represents that the terminal device may transmit the UL excitation carrier, and "1" represents that the terminal device may not transmit the UL excitation carrier. That is, the network device receives "0" and determines that the terminal device does not have UL excitation carrier transmission capability, and receives "1" and determines that the terminal device has UL excitation carrier transmission capability. It should be understood that the above bit information is merely exemplary, and the UL excitation carrier transmission capability may also be represented by other forms of information.

In one possible implementation manner, the AmBC capability information may further include a type of the terminal device, where the type of the terminal device includes a first type and a second type, the first type of terminal device has cellular communication capability and UL excitation carrier transmission capability, and the second type of terminal device has cellular communication capability, UL excitation carrier transmission capability and AmBC communication capability. The type of the terminal device reported by the terminal device may be a type agreed in advance between the terminal device and the network device, or a type predefined by a protocol, which is not limited in the present application. For example, it may also be identified by 1bit, "1" indicates that the type of the terminal device is type one, and "2" indicates that the type of the terminal device is type two. That is, the network device receives "1" which may determine that the terminal device is a first type of terminal device, and receives "2" which may determine that the terminal device is a second type of terminal device. The network device may determine a scheduling policy based on the type of the terminal device. For example, when a terminal device of a first type and a terminal device of a second type coexist in the network, the network device may schedule the terminal device of the first type to transmit the UL excitation carrier first. In this way, it is helpful to reduce the crosstalk problem caused by the terminal device of the second type transmitting the UL excitation carrier and the AmBC signal at the same time.

Further, optionally, the AmBC capability information may also include location information of the terminal device. The network device may determine which terminal devices in which locations to schedule based on the location information reported by the terminal devices.

In the application, the network device may instruct the terminal device to measure the AmBC resource pool. I.e. the network device may instruct the terminal device how to measure the AmBC resource pool. For example, time frequency resources (e.g. some time frequency resources with the same frequency as the AmBC resource pool and advanced in time) which need to be measured, measurement quantity (e.g. average value of received power of the carrier to be measured) and the like can be indicated. In one possible implementation, the network device may send the indication information to the terminal device. Accordingly, the terminal device receives the indication information from the network device. The indication information is used for indicating the terminal device to measure the AmBC resource pool, where the indication information may include a carrier to be measured in the AmBC resource pool to be measured and a measurement quantity, for example, a time-frequency resource where the carrier to be measured is located and/or an average value of received power on the carrier to be measured. It should be understood that the indication information may be predetermined by the terminal device and the network device, or may be predefined by a protocol, which is not limited in this application. For example, the indication information may be several indication characters, which may indicate how the terminal device measures the AmBC resource pool. The specific form of the indication information may also be any other possible form, which is not limited in this application.

In a possible implementation manner, the terminal device may measure the AmBC resource pool according to the received indication information to obtain measurement information of the AmBC resource pool, where the measurement information of the AmBC resource pool may identify (i.e., reflect) communication quality of the terminal device in the AmBC communication. Illustratively, the terminal device may measure the AmBC resource pool according to the indication information to obtain measurement information of the AmBC resource pool.

And step 402, the terminal equipment reports the AmBC capacity information and the measurement information of the AmBC resource pool to the network equipment. Accordingly, the network device may receive the AmBC capability information reported from the terminal device and the measurement information of the AmBC resource pool.

It should be noted that the terminal device may send the AmBC capability information and the measurement information of the AmBC resource pool to the network device together, or may send the AmBC capability information and the measurement information of the AmBC resource pool to the network device separately, which is not limited in this application.

And step 403, the network device performs AmBC carrier scheduling according to the AmBC capability information and the measurement information of the AmBC resource pool.

In one possible implementation, the network device may first determine whether to perform AmBC carrier scheduling, which may be determined by any one of the following two implementations.

In the first implementation manner, the network device determines whether AmBC carrier scheduling is required.

And when the network equipment determines that the AmBC carrier scheduling triggering condition is met, determining that AmBC carrier scheduling needs to be carried out. Illustratively, the network device may determine whether the AmBC carrier scheduling trigger condition is satisfied according to the measurement information of the AmBC resource pool. That is to say, the network device may evaluate the AmBC resource pool based on the measurement information of the AmBC resource pool reported by the terminal device, so as to determine whether the AmBC carrier scheduling needs to be performed. For example, when the measurement information of the AmBC resource pool includes an average value of the received power of the terminal device on the carriers to be measured in the measured AmBC resource pool, if the value is determined to be smaller than the threshold value, the network device determines that the AmBC carrier scheduling trigger condition is satisfied, that is, it is determined that the AmBC carrier scheduling needs to be performed.

And in the second implementation mode, the terminal equipment sends an AmBC carrier scheduling request to the network equipment.

In a possible implementation manner, the terminal device may determine whether the AmBC carrier scheduling trigger condition is satisfied according to measurement information of the AmBC resource pool. And when the measurement information of the AmBC resource pool comprises the average value of the receiving power of the terminal equipment on the carrier wave to be measured in the measured AmBC resource pool, if the terminal equipment determines that the value is smaller than the threshold value, determining that the AmBC carrier wave scheduling triggering condition is met. Or when the terminal equipment determines that the average power of the received power of the AmBC carrier wave received on certain time-frequency resources is smaller than a preset value, the AmBC carrier wave scheduling triggering condition is determined to be met. Further, when the terminal device determines that the AmBC carrier scheduling trigger condition is met, the terminal device sends an AmBC carrier scheduling request to the network device, wherein the AmBC carrier scheduling request is used for requesting the network device to perform AmBC carrier scheduling. After receiving the AmBC carrier scheduling request from the terminal equipment, the network equipment determines that AmBC carrier scheduling is required. It should be noted that, the above-mentioned terminal device determining whether the AmBC carrier scheduling trigger condition is satisfied is only an example, and other AmBC carrier scheduling trigger conditions may also be autonomously determined by the terminal device.

The above AmBC carrier scheduling request may be represented by one or more bits of information. For example, the AmBC carrier scheduling request is represented by bit information "00", and the network device may determine that the terminal device needs to perform AmBC carrier scheduling when receiving the bit information "00" from the terminal device. It should be noted that the above bit information is merely exemplary, and the AmBC carrier scheduling request may also be represented by other forms of information.

In a possible implementation manner, the AmBC carrier scheduling request may further include parameters such as time-frequency resources and power that need to perform AmBC carrier scheduling. For example, a power boost of the AmBC carrier over a certain frequency band by several dB is requested. The terminal device may transmit the AmBC carrier scheduling request to the network device through a Medium Access Control (MAC) Control Element (CE) or Radio Resource Control (RRC) message.

The above two implementation manners for determining whether AmBC carrier scheduling is required are only examples, and the application does not limit how to determine that AmBC carrier scheduling is required. In addition, which implementation manner is selected to determine whether the AmBC carrier scheduling is required or not may be predetermined by the network device and the terminal device, or may be specified by a protocol, or may be selected according to some factors, which is not limited in this application.

In the application, after the network device determines that the AmBC carrier needs to be scheduled based on the first implementation manner, the second implementation manner, or any other possible manner, the network device may determine an AmBC carrier scheduling policy according to the measurement information of the AmBC resource pool. The AmBC carrier scheduler of the network equipment can operate an AmBC carrier scheduling algorithm to determine the AmBC carrier scheduling strategy. The AmBC carrier scheduling policy includes, but is not limited to, one or more of a type of scheduled AmBC carrier (e.g., a normal DL signal, a normal UL signal, a DL excitation carrier, or a UL excitation carrier), a terminal device associated with the scheduled AmBC carrier (a terminal device for receiving a normal DL signal, a terminal device for transmitting a normal UL signal, an AmBC terminal device for transmitting a UL excitation carrier), and a time-frequency resource in which the scheduled AmBC carrier is located.

In a possible implementation manner, the network device may further send the AmBC configuration information to the terminal device. Accordingly, the terminal device receives the AmBC configuration information from the network device. The AmBC configuration information includes an AmBC Radio Network Temporary Identity (RNTI) of the terminal device in the AmBC communication.

When the network device determines that the type of the scheduled AmBC carrier is the UL excitation carrier, a scheduling instruction may be sent to the terminal device through Downlink Control Information (DCI). Accordingly, the terminal device may receive the scheduling instruction transmitted through the DCI from the network device. The scheduling instruction may include relevant parameters of the UL excitation carrier, such as time-frequency resources, waveforms, power, and the like where the UL excitation carrier is located. Of course, the relevant parameters of the UL excitation carrier may also be determined by the terminal device itself. The scheduling instruction is used for instructing the terminal equipment to send the parameters of the UL excitation carrier wave, and the scheduling instruction can be scrambled through AmBC RNTI of the terminal equipment. Further, optionally, the terminal device may descramble the scheduling instruction according to the AmBC RNTI, and send the UL excitation carrier to the network device according to the descrambled scheduling instruction. For example, the terminal device may transmit an UL excitation carrier to the network device on the scheduled time-frequency resources.

When the network device determines that the scheduled AmBC carrier is a normal UL/DL signal, the network device may schedule according to a normal cellular data UL/DL scheduling procedure.

When the network device determines that the scheduled AmBC carrier is a DL-excited carrier, the network device may transmit the DL-excited carrier on the scheduled time-frequency resource.

As can be seen from steps 401 to 403, the network device may implement scheduling of the AmBC carrier according to the AmBC capability information reported by the terminal device and the measurement information of the AmBC resource pool. That is, the present application provides a scheduling scheme for an AmBC carrier in an AmBC communication network.
