[0048] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0049] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0050] The main solution of the embodiment of the present application is: receiving downlink control information sent by a base station placed outside the human body; based on the downlink control information, capturing images of the inside of the human digestive cavity to obtain image data; sending the image data to several relay devices placed on the surface of the human body, and the several relay devices sending the received image data to the base station, and the base station uploading it to the medical server.

[0051] Since the capsule endoscope in the prior art receives control information from the base station through the 5G downlink channel, the capsule endoscope uses wireless resources to send image data to the relay device within a short distance through the side channel, and the relay device then sends the image data to the base station through the 5G uplink channel, and the base station sends the image data to the medical server. When the relay device receives image data from the capsule endoscope, due to the attenuation or change of the received signal caused by the position movement and direction rotation of the capsule endoscope in the human body, the relay device may not be able to correctly receive or decode the image data, resulting in the image data cannot be transmitted to the medical server, or more power is consumed for retransmitting the image data.

[0052] The professional terms involved in this application are:

[0053] Base station: It is an important component of the communication network, mainly used to receive and send wireless signals, responsible for communicating with user equipment (UE) and transmitting data to the server.

[0055] Relay equipment: Usually used to expand the coverage of communication signals. In network communications, repeaters can receive, amplify and forward signals to extend the transmission distance of the network.

[0056] Capsule endoscope: It is a small, wireless medical imaging device that can be swallowed by the patient to take images inside the digestive tract. The images are sent to an external device through a camera and wireless transmission technology. Doctors can analyze these images to help diagnose digestive system diseases.

[0057] Physical Downlink Control Channel (PDCCH): It is a channel used to transmit control information in the downlink and is mainly responsible for scheduling and controlling resource allocation of user equipment.

[0058] Physical Downlink Shared Channel (PDSCH): A channel used to transmit user data in the downlink and is the main channel for user equipment to receive data.

[0059] Side Link: Mainly used for direct communication between devices, usually for device-to-device communication. In LTE and 5G networks, the side link allows user devices to exchange data directly with other user devices without going through a base station.

[0060] The present application receives image data collected by a capsule endoscope through multiple relay devices, then forwards the image data to a base station, and the base station then uploads the image data to a medical server, thereby solving the problem of unstable signal transmission of capsule endoscopes in the prior art and improving the reliability of signal transmission of capsule endoscopes.

[0061] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a capsule endoscope communication device, etc. The following takes the capsule endoscope communication device as an example to illustrate this embodiment and the following embodiments.

[0062] Based on this, the present application embodiment provides a capsule endoscope communication method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the capsule endoscope communication method of the present application.

[0063] In this embodiment, the capsule endoscope communication method is applied to a capsule endoscope, and the capsule endoscope is placed in a human digestive cavity, comprising steps S10 to S30:

[0064] Step S10, receiving downlink control information sent by a base station placed outside the human body;

[0065] It should be noted that the base station refers to the device outside the human body that is responsible for sending control commands and receiving and uploading capsule endoscope image data. Downlink control information is used to guide the operation of the capsule endoscope, including information such as adjusting the camera shooting cycle, communication transmission object, communication transmission rate, image data configuration, etc.

[0066] It is understandable that the capsule endoscope placed in the human digestive cavity receives control information from an external base station through wireless communication technology (such as 4G / 5G communication, Wi-Fi, Bluetooth or dedicated medical wireless frequency) to allow an external operator to control the behavior of the capsule endoscope to optimize image acquisition and communication transmission effects.

[0067] Step S20, based on the downlink control information, collecting images of the interior of the human digestive cavity to obtain image data;

[0068] It can be understood that in order to obtain image data inside the human digestive cavity for medical diagnosis, the capsule endoscope is equipped with a micro camera. When the capsule endoscope enters the human digestive cavity, the image inside the human digestive cavity is captured by the micro camera based on the downlink control information, and the image data of digital information is obtained by processing.

[0069] Step S30, sending the image data to a plurality of relay devices placed on the surface of the human body, the plurality of relay devices sending the received image data to the base station, and the base station uploading the image data to the medical server.

[0070] It should be noted that the medical server refers to a server that is connected to a base station, can receive image data sent by the base station, and store and process the image data for doctors to make diagnoses.

[0071] It is understandable that in order to ensure that image data can be safely and effectively transmitted from the capsule endoscope to the medical server for doctors to analyze and diagnose, the capsule endoscope transmits the image data to several relay devices on the human body surface via wireless signals, and the several relay devices then transmit the image data to the base station, which is finally uploaded to the medical server by the base station.

[0072] In a feasible implementation manner, the step of receiving downlink control information sent by a base station placed outside the human body includes:

[0073] Step S101, receiving the downlink control information sent by the base station through a physical downlink control channel, where the downlink control information is generated by the base station based on a preset first downlink control information format;

[0074] The first downlink control information format includes at least one or more of a second downlink control information format and a wireless resource configuration, and the second downlink control information format includes at least medical server control data.

[0075] It should be noted that the physical downlink control channel refers to a communication channel used to transmit downlink control information, which is responsible for transmitting the control information of the base station to the capsule endoscope. The downlink control information is sent by the base station and is used to control the operation of the capsule endoscope, such as adjusting camera parameters or indicating when to start collecting images or instructing the capsule endoscope how to communicate and transmit image data.

[0076] In addition, it should be noted that the first downlink control information format is a preset information format that specifies the structure and content of the downlink control information, and may include the second downlink control information format, wireless resource configuration information, function control instructions, and image configuration information, etc. The image configuration information may include information such as image data cycle, image data volume per frame, image acquisition frequency, etc. The wireless resource configuration information is configuration information used for the capsule endoscope to schedule wireless communication resources for communication transmission, and may set the communication transmission cycle or channel division rules (such as time division, frequency division, etc.). The second downlink control information format includes at least medical server control data, which is used to send specific control instructions from the medical server to the capsule endoscope.

[0077] It can be understood that the capsule endoscope receives the downlink control information generated by the external base station based on the first downlink control information format through the physical downlink control channel, ensuring that the capsule endoscope can receive and execute control commands from the external base station to achieve accurate image acquisition and data transmission, thereby improving the stability of the capsule endoscope communication transmission.

[0078] In this embodiment, a dedicated medical wireless frequency and advanced coding and modulation technology are used to ensure accurate and efficient transmission of downlink control information. Combined with wireless resource management, resource allocation is dynamically adjusted to adapt to different communication transmission requirements. The medical server control data can accurately guide the operation of the capsule endoscope and improve the accuracy and efficiency of diagnosis. The capsule endoscope system can achieve efficient, stable and accurate image acquisition and data transmission, providing doctors with clear gastrointestinal images, thereby improving the accuracy and efficiency of diagnosis.

[0079] In a feasible implementation manner, after the step of receiving downlink control information sent by a base station outside the human body, the step further includes:

[0080] Step S102, based on the second downlink control information format, generating control feedback information according to the downlink control information;

[0081] It should be noted that the control feedback information refers to feedback information sent by the capsule endoscope to the base station, which is used to report the status of the capsule endoscope or respond to the control data of the medical server in the downlink control information.

[0082] It can be understood that the capsule endoscope parses the content of the second downlink control information format according to the received downlink control information (based on the first downlink control information format), and generates control feedback information accordingly, providing the capsule endoscope with a response to the downlink control information sent by the base station, so that the base station can understand the status and execution of the capsule endoscope, and perform further control and adjustment.

[0083] Step S103: Based on the wireless resource configuration, wireless resources of the side channel are allocated to the several relay devices, and the control feedback information is sent to the several relay devices through the side channel. The relay device that receives the control feedback information forwards the control feedback information to the base station through an uplink channel, and the base station regenerates the downlink control information according to the received control feedback information based on a preset first downlink control information format.

[0084] It should be noted that wireless resource configuration refers to the configuration information of the base station dynamically allocating wireless communication resources to different devices according to network conditions and device requirements. The side channel is used for communication between the relay device and the capsule endoscope or between intermediate devices.

[0085] It can be understood that, based on the wireless resource configuration information, specific wireless resources are allocated to one or more relay devices, and the control feedback information is sent to these relay devices through the side channel. After each of these relay devices receives the control feedback information sent by the capsule endoscope, they forward it to the base station through the uplink channel, ensuring that the control feedback information can be effectively transmitted from the capsule endoscope to the base station, thereby ensuring the smoothness of the communication link between the capsule endoscope, the relay device and the base station, and avoiding interference with other wireless communications.

[0086] In this embodiment, through the control feedback adjustment mechanism of the communication link, the capsule endoscope system can achieve efficient, stable and accurate control information transmission and feedback, providing doctors with real-time device communication status information, thereby improving the accuracy and efficiency of diagnosis. At the same time, dynamic wireless resource management and enhanced signal transmission capabilities ensure the reliability and stability of communication, further optimizing the communication performance of the entire system.

[0087] In a feasible implementation manner, the step of sending the image data to a plurality of relay devices placed on the surface of the human body includes:

[0088] Step S301, based on the second downlink control information format, generating sidelink communication information according to the downlink control information and the image data;

[0089] It should be noted that the side communication information is information used to transmit image data between the capsule endoscope and the relay device, and may include necessary control information and data payload. The process of generating the side communication information may involve data encoding, packaging and modulation to meet the requirements of wireless transmission.

[0090] It can be understood that the capsule endoscope generates side communication information based on the second downlink control information format, according to the received downlink control information (generated based on the first downlink control information format) and the collected image data, and ensures the integrity and transmissibility of the data by encapsulating the image data into a format suitable for transmission through a wireless channel.

[0091] Step S302: Based on the wireless resource configuration, wireless resources of the side channel are allocated to the plurality of relay devices, so as to send the image data to the plurality of relay devices through the side channel and the side communication information.

[0092] It can be understood that, based on the configuration information of the wireless resources, specific wireless resources are allocated to one or more relay devices to dynamically select a suitable transmission path between multiple relay devices so that these relay devices can receive side communication information through the side channel, ensuring that the side communication information can be effectively transmitted from the capsule endoscope to the relay device while avoiding interference with other wireless communications.

[0093] In this embodiment, the capsule endoscope can generate side communication information suitable for wireless transmission based on the downlink control information and image data. Through wireless resource configuration and efficient management of side channels, it can ensure that the image data can be stably transmitted from the capsule endoscope to the relay device. In addition, according to real-time network conditions and equipment requirements, dynamic wireless resource management and enhanced information transmission capabilities can ensure the reliability and stability of communication, further optimizing the communication performance of the entire system.

[0094] In a feasible implementation manner, the method is applied to a relay device, and the relay device is placed on the surface of a human body, comprising steps S40 to S50:

[0095] Step S40, receiving image data sent by a capsule endoscope placed in a human digestive cavity, wherein the image data is obtained by collecting images of the interior of the human digestive cavity based on downlink control information sent by a base station placed outside the human body after the capsule endoscope receives downlink control information.

[0096] It can be understood that after the capsule endoscope is placed outside the human body, the base station sends the downlink control information, collects the image data in the human digestive cavity and sends the image data to the relay device placed on the surface of the human body for further processing and transmission.

[0097] Step S50, sending the image data to the base station, and uploading the image data to the medical server by the base station.

[0098] It is understandable that the relay device sends the received image data to the base station, and the base station uploads this data to the medical server for storage and analysis, ensuring that the image data can be stably and effectively transmitted from the capsule endoscope to the medical server for doctors to diagnose.

[0099] This embodiment provides a capsule endoscope communication method, which receives image data collected by a capsule endoscope through multiple relay devices, then forwards the image data to a base station, and then the base station uploads the image data to a medical server, thereby solving the problem of unstable capsule endoscope signal transmission in the prior art and improving the reliability of capsule endoscope signal transmission.

[0100] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the first embodiment can refer to the above introduction, and will not be repeated in the following. Figure 2 The capsule endoscope communication method is applied to a base station, and the base station is placed outside the human body. The method includes steps S60 to S80:

[0101] Step S60, obtaining downlink control information;

[0102] It can be understood that the base station placed outside the human body obtains downlink control information to be sent to the capsule endoscope placed in the human digestive cavity, so as to guide the image acquisition and communication transmission behavior of the capsule endoscope.

[0103] Step S70, sending the downlink control information to a capsule endoscope placed in a human digestive cavity, and the capsule endoscope collects images of the interior of the human digestive cavity based on the downlink control information, and after obtaining image data, sends the image data to a plurality of relay devices placed on the surface of the human body;

[0104] It can be understood that the base station controls the capsule endoscope to collect images by sending downlink control information to the capsule endoscope, and the capsule endoscope sends the image data obtained after completing the image collection to one or more relay devices placed on the surface of the human body.

[0105] Step S80, receiving the image data sent by the plurality of relay devices, and uploading the image data to a medical server.

[0106] It can be understood that the base station receives image data from several relay devices and uploads the data to the medical server, ensuring that the image data is stably and effectively transmitted from the capsule endoscope to the medical server for doctors to perform diagnostic analysis.

[0107] In a feasible implementation manner, the step of acquiring downlink control information includes:

[0108] Step S601, receiving uplink control information sent by the plurality of relay devices through an uplink channel, wherein the uplink control information at least includes relay device information and endoscope control data;

[0109] It should be noted that the uplink control information refers to the information sent by the relay device to the base station, which may include the status and location of the relay device, and the control data of the capsule endoscope.

[0110] It can be understood that the base station receives uplink control information from the relay device through the uplink channel, collects information of the relay device and control requirements of the capsule endoscope, so as to perform resource allocation and control instruction generation.

[0111] Step S602, allocating wireless resources to the plurality of relay devices according to the relay device information, and obtaining a wireless resource allocation result;

[0112] It can be understood that the base station determines the network status and equipment requirements of each relay device based on the relay device information received from several relay devices, dynamically allocates wireless resources, ensures that the relay device can effectively communicate with the base station, and optimizes the spectrum utilization of the network.

[0113] Step S603: Generate downlink control information according to the wireless resource allocation result and the control data.

[0114] It can be understood that the base station combines the wireless resource allocation results and control data to generate downlink control information, and generates downlink control instructions sent to the capsule endoscope to guide the image acquisition and communication transmission of the capsule endoscope to achieve stable and efficient image acquisition and data transmission.

[0115] In this embodiment, through efficient uplink information transmission, dynamic wireless resource management, reliable downlink control instruction generation and precise image acquisition control, precise operation of the capsule endoscope and effective transmission of image data are achieved, which not only improves the quality and efficiency of medical diagnosis, but also enhances the communication performance and reliability of the entire system by optimizing wireless resource allocation and improving the security of data transmission.

[0116] In a feasible implementation manner, the plurality of relay devices include a first relay device and a second relay device, and the step of allocating wireless resources to the plurality of relay devices according to the uplink control information to obtain a wireless resource allocation result includes:

[0117] Step S6021: Allocate a first wireless resource to a first uplink channel of the first relay device according to the uplink control information;

[0118] It should be noted that the first relay device refers to a relay device in the system, which is responsible for receiving the data of the capsule endoscope and forwarding it to the base station. The first wireless resource refers to the wireless spectrum or time resource allocated to the first relay device.

[0119] It can be understood that the base station evaluates the communication needs and status of the first relay device based on the uplink control information sent by the first relay device, and allocates appropriate wireless resources to its uplink channel for receiving data sent by the capsule endoscope and sending data to the base station, ensuring that the first relay device can efficiently and stably send the image data it collects to the base station.

[0120] Step S6022: Allocate a second wireless resource to a second uplink channel of the second relay device according to the uplink control information, where the second wireless resource is orthogonal to the first wireless resource in the time domain or the frequency domain;

[0121] It should be noted that the second relay device refers to another type of relay device in the system that assists the first relay device in data transmission, and has the same or similar functions as the first relay device. The second wireless resource refers to the wireless time or spectrum resource allocated to the second relay device, which is orthogonal to the first wireless resource.

[0122] It can be understood that the base station also allocates subsequent wireless resources to its uplink channel based on the uplink control information sent by the second relay device, which is used to receive data sent by the capsule endoscope and send data to the base station, and these resources are orthogonal to the resources of the first relay device in the time domain or frequency domain, ensuring that the second relay device can also transmit data efficiently and stably while avoiding information interference with the first relay device.

[0123] Step S6023: Obtain a wireless resource allocation result according to the first wireless resource and the second wireless resource.

[0124] It should be noted that the wireless resource allocation result refers to the final plan of the base station to allocate wireless resources to all relay devices. The number of relay devices is not limited here. The wireless resource allocation result may include the wireless resource allocation results of one or more relay devices divided according to time slots or spectrum.

[0125] It is understandable that the base station comprehensively considers the wireless resource allocation situations of the first and second relay devices to form a final wireless resource allocation plan to ensure that all relay devices can effectively receive data from the capsule endoscope and transmit the data to the base station without interfering with each other.

[0126] In this embodiment, efficient and stable communication between multiple relay devices is achieved through dynamic allocation of wireless resources of relay devices, while interference between devices is reduced, which not only improves the efficiency and quality of data transmission, but also enhances the capacity and anti-interference capability of the system, providing a stable and reliable communication foundation for the communication transmission of capsule endoscopes, thereby improving the quality and efficiency of medical diagnosis.

[0128] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those of the first and second embodiments mentioned above can be referred to the above introduction and will not be repeated later.

[0129] For example, in order to help understand the implementation process of the capsule endoscope communication method obtained by combining the first embodiment and the second embodiment, please refer to Figure 3 , Figure 3 A brief flow diagram of a capsule endoscope communication method is provided, which includes a capsule endoscope, multiple relay devices, a base station and a medical server, wherein the base station is connected to the medical server. This exemplary embodiment mainly includes the following steps:

[0130] Step 0: corresponding to one capsule endoscope, configure a plurality of relay devices (eg, a first relay device and a second relay device) for receiving and forwarding image data from the capsule endoscope.

[0131] A: The multiple relay devices send uplink control information containing service requests (for example, requesting the base station to configure periodic wireless resources for the transmission of periodic image data) to the base station through an uplink channel (for example, a 5G physical uplink control channel, a physical uplink shared channel, or a physical random access channel).

[0132] The uplink control information may include the period of image data (e.g., the number of frames per second), the (maximum) data volume of each frame, the estimated time required for image data transmission (e.g., the time the capsule endoscope performs detection in the human body), and the identification (ID) of the capsule endoscope.

[0133] B: The base station configures radio resources of uplink channels for the multiple relay devices. For example, a first radio resource is configured for a first uplink channel of the first relay device; and a second radio resource is configured for a second uplink channel of the second relay device.

[0134] The first wireless resource and the second wireless resource may be the same in the time domain, for example, the same time slot or OFDM symbol, for example, the same period, or the first wireless resource and the second wireless resource may be orthogonal (non-overlapping) in the frequency domain, for example, different resource blocks.

[0135] Step 1: The capsule endoscope receives downlink control information from the base station through a downlink channel (e.g., a 5G physical downlink control channel or a physical downlink shared channel). The downlink control information may be:

[0136] 1. Schedule a third wireless resource (eg, a periodic time slot and a resource block in the frequency domain) of a sidelink channel (eg, a channel between devices; sidelink) used by the capsule endoscope to transmit image data.

[0137] The period of the third wireless resource may be the same as the period of the first wireless resource and the second wireless resource, the period of the third wireless resource may be an integer multiple of the period of the first wireless resource and the second wireless resource, or the period of the first wireless resource and the second wireless resource may be an integer multiple of the period of the third wireless resource.

[0138] 2. Contains control data from the medical server. The control data can indicate the capsule endoscope's image capture cycle, image resolution (corresponding to the size of the image data), etc.

[0139] For example, Figure 4 As shown, Figure 4 The example schematic diagram of the communication cycle provided for the third embodiment of the capsule endoscope communication method of the present application includes:

[0140] 1. The capsule endoscope sends image data to a relay device in a first cycle. For example, the capsule endoscope sends first image data at a first time point and sends second image data at a second time point. The interval between the time points is the first cycle, and the capsule endoscope can cache image data at multiple time points.

[0141] 2. The relay device sends the image data to the base station in a second period. The second period may be the same as the first period, or may be an integer multiple of the first period greater than 1. The image data sent by the relay device is an integration of image data received at multiple time points.

[0142] 3. The capsule endoscope receives downlink control information from the base station at a third period. The third period may be the same as the second period, or an integer multiple greater than 1 of the second period, or an integer multiple greater than 1 of the first period.

[0143] Step 2: The capsule endoscope uses the third wireless resource to (periodically) send the image data to the multiple relay devices within a short distance through the side channel.

[0144] Step 3: The multiple relay devices send the received image data to the base station through the first wireless resource and the second wireless resource respectively.

[0145] If one of the relay devices (eg, the second relay device) successfully receives the image data, the relay device sends the image data to the base station via an uplink channel (eg, using the second wireless resource).

[0146] If one of the relay devices (eg, the first relay device) fails to successfully receive the image data, the relay device may not transmit any data to the base station; or transmit feedback information of "failed to successfully receive the image data" to the base station via the first wireless resource.

[0147] Step 3A (as an optional alternative to step 3), allocates a fourth wireless resource to the multiple relay devices for sending and receiving information on whether the image data from the capsule endoscope is successfully received (for example, a 1-bit field in the side control information).

[0148] The base station may configure the fourth wireless resource to the multiple relay devices. The fourth wireless resource may be a resource orthogonal in the time domain, for example, the fourth wireless resource includes multiple resources located in different time slots, each resource being located in a time slot. The number of the multiple resources may be equal to the number of the multiple relay devices. For example, the first relay device may send first information to other relay devices through one of the wireless resources in the fourth wireless resource, and the first information indicates that the first relay device has not successfully received the image data. The second relay device may send second information to other relay devices through one of the wireless resources in the fourth wireless resource, and the second information indicates that the second relay device has successfully received the image data. The third relay device may send third information to other relay devices through one of the wireless resources in the fourth wireless resource, and the third information indicates that the third relay device has successfully received the image data.

[0149] According to the above-mentioned first information, second information, and third information, the relay device that has not successfully received the image data (for example, the first relay device) does not transmit any data to the base station, while one of the relay devices that successfully received the image data (for example, the second relay device or the third relay device) can send the image data to the base station.

[0150] When multiple relay devices successfully receive the image data, which relay device sends the image data to the base station is determined according to the order (positive or negative) of the fourth wireless resource. For example, the wireless resource allocated to the second relay device is in time slot n, and the wireless resource allocated to the third relay device is in time slot n+1. Then, according to the positive order of the time slot arrangement, the second relay device sends the image data to the base station.

[0151] In addition, the base station may also configure the number (e.g., maximum number) of relay devices that send image data to the base station according to the quality of the uplink channel. For example, if the quality of the uplink channel (e.g., RSRP, signal-to-noise ratio, bit error rate, etc.) is higher than a certain threshold, the number is configured to be 1. If the quality of the uplink channel (e.g., RSRP, signal-to-noise ratio, bit error rate, etc.) is lower than a certain threshold, the number is configured to be all relay devices.

[0152] Step 4: The base station receives image data from the multiple relay devices respectively through multiple uplink channels.

[0153] If the base station receives image data from one or more relay devices, the base station sends the image data to the medical server. If the base station does not receive any image data, the base station sends a retransmission instruction / request for the image data to the capsule endoscope via a downlink channel.

[0154] Optionally, the capsule endoscope is configured with simplified RF and baseband hardware for receiving an enhanced physical downlink control channel. The capsule endoscope is only configured with hardware and algorithms for receiving and decoding a physical downlink control channel (PDCCH), but not with hardware and algorithms for receiving a physical downlink shared channel (PDSCH), including:

[0155] 1. The capsule endoscope receives downlink control information from the base station through the enhanced PDCCH.

[0156] In the frequency domain, the capsule endoscope searches for the enhanced PDCCH in a predefined narrow bandwidth.

[0157] In the time domain, the period of the enhanced PDCCH is the same as the transmission period of the image data, or is an integer fraction of the transmission period of the image data, or is an integer multiple of the transmission period of the image data.

[0158] Downlink Control Information (DCI) is carried by the enhanced PDCCH (not by the PDSCH, so the capsule endoscope does not need to receive and decode the PDSCH). The enhanced PDCCH can be repeatedly sent in multiple time slots.

[0159] Option 1: Based on the existing DCI format 3_0 of 5G, a new DCI format is introduced to transmit control data from the medical server and configuration information of the wireless resources of the side channel. The capsule endoscope receives and decodes a first DCI using the new DCI format. The new DCI format can carry more data (e.g., hundreds of bits) than the existing DCI format can carry (e.g., tens of bits).

[0160] Option 2: The capsule endoscope receives and decodes the first-stage DCI (based on the existing DCI format). The first-stage DCI may indicate multiple second-stage DCIs (based on the existing DCI format or the new DCI format). According to the indication of the first-stage DCI, the capsule endoscope may receive and decode the multiple second-stage DCIs. The multiple second-stage DCIs may include the upper layer data; or the first-stage DCI and the multiple second-stage DCIs may include the upper layer data.

[0161] 2. The capsule endoscope sends feedback information associated with the enhanced PDCCH to the base station through the relay device along with the image data, including:

[0162] ACK (acknowledgement): successful reception / decoding of the upper layer data (the enhanced PDCCH, or DCI);

[0163] NACK (negative acknowledgement): The upper layer data (the enhanced PDCCH or DCI) was not successfully received / decoded.

[0164] Among them, the existing DCI format 3_0 for scheduling sideline communication generally includes the following fields:

[0165] 1. Resource pool identifier: Indicates the specific resource pool used for the transfer.

[0166] 2. Time interval: Define the time interval for timing control in the scheduling process.

[0167] 3.HARQ process number: Identifies a specific process related to HARQ (Hybrid Automatic Repeat reQuest), allowing the sender to track the status of each transmission.

[0168] 4. New Data Indicator: Indicates whether this transmission contains new data, helping the receiver confirm how to process the data.

[0169] 5. Lowest index of subchannel allocation for initial transmission: indicates the lowest index of the subchannel allocated for initial transmission.

[0170] 6. The lowest index of the RB set allocated for initial transmission: indicates the lowest index of the resource block (RB, ResourceBlock) set allocated for initial transmission.

[0171] 7. SCI format 1-A field: includes frequency resource allocation and time resource allocation.

[0172] 8.PSFCH to HARQ feedback timing indicator: indicates the timing relationship between PSFCH (physical sidelink feedback channel) and HARQ feedback.

[0173] 9. PUCCH resource indicator: indicates specific resources used for PUCCH (Physical Uplink Control Channel).

[0174] 10. Configuration index: used to configure monitoring related information.

[0175] 11. Counter side channel allocation index: used to track the allocation of side channel.

[0176] 12. HARQ ACK codebook configuration: Indicates ACK / NACK feedback information according to different HARQ ACK codebook configurations.

[0177] Exemplarily, the fields in the new DCI format include: all or part of the fields in the above-mentioned DCI format 3_0; and control data block 1 from the medical server, control data block 2 from the medical server, ..., control data block N from the medical server.

[0178] Exemplarily, the first-stage DCI includes: all or part of the fields in the above-mentioned DCI format 3_0; a flag field indicating whether the second-stage DCI exists; and a field for scheduling the second-stage DCI.

[0179] This field may indicate the number of second-stage DCIs, the size of the second-stage DCI (eg, how many bits), and the time domain resource (eg, time slot or OFDM symbol) of the PDCCH containing the second-stage DCI.

[0180] The second stage DCI includes: control data block 1 from the medical server, control data block 2 from the medical server, ..., control data block N from the medical server.

[0181] In this embodiment, image data collected by the capsule endoscope is received by multiple relay devices, and then forwarded to a base station, which then uploads the image data to a medical server, thereby achieving precise operation of the capsule endoscope and stable and effective transmission of image data, solving the problem of unstable signal transmission of capsule endoscopes in the prior art, and improving the reliability of signal transmission of capsule endoscopes.
