[0036] The communication methods, devices, electronic devices, and storage media provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0037] The terms "first" and "second," etc., in the specification and drawings of this application are used to distinguish different objects, rather than to describe a specific order of objects. For example, "first time-frequency position" and "second time-frequency position," etc., are used to distinguish different signals, rather than to describe a specific order of signals.

For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.

Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0040] The term "and / or" as used in this application includes using either one of two methods or using both methods simultaneously.
[0041] In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0042] As described in the background art, in related technologies, the number of terminals within a designated area may be too large, resulting in some terminals within that area lacking network access, thus affecting the user's communication experience. Based on this, embodiments of this application provide a communication method, apparatus, electronic device, and storage medium. Since the feedback signal includes the location information of the terminal, the network device can determine the target area based on the feedback signal. Furthermore, since the feedback signal is sent by the terminal upon receiving the detection signal and when the terminal has no network access, the network device can determine that the terminal exists in the target area and that the terminal in the target area has no network service. When a terminal exists in the target area and the terminal in the target area has no network access, the network device provides communication services to the target area, enabling network services to terminals without network service, improving the user's communication experience, and increasing the flexibility of the access signal coverage.
[0043] The communication method, apparatus, electronic device, and storage medium provided in this application can be applied to communication systems, such as... Figure 1 As shown, the communication system includes network device 101 and terminal 102. Typically, in practical applications, the connection between these devices can be wireless. To facilitate a clear and intuitive representation of the connection relationships between the devices, Figure 1 Solid lines are used to represent the meaning.
[0044] Among them, network device 101 can send a detection signal to terminal 102. When it receives the signal to be identified sent by the terminal, it analyzes the signal to be identified to obtain the signal identifier of the signal to be identified and the location information of the terminal. When the signal type of the signal to be identified is a feedback signal, it determines to provide communication services to the target area.
[0045] In this embodiment of the application, terminal 102 can receive a target signal sent by network device 101, and perform parsing processing on the target signal to obtain the signal identifier of the target signal. When the signal type of the target signal is a detection signal and terminal 102 has no network access, it sends a feedback signal to network device 102.
[0046] For example, the network device that performs the communication method provided in the embodiments of this application can be a base station, which can be a commonly used base station, an evolved node base station (eNB), a next-generation node base station (gNB), a new radio eNB, a macro base station, a micro base station, a high-frequency base station, or a transmission and reception point (TRP), etc.
[0047] For example, terminal 102 can be a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phone, personal digital assistant (PDA), augmented reality (AR) / virtual reality (VR) device, etc. This disclosure does not impose any special restrictions on the specific form of the terminal. It can interact with the user through one or more methods such as keyboard, touchpad, touch screen, remote control, voice interaction or handwriting device.
[0048] For example, with Figure 1 Taking a commonly used base station as an example, the hardware structure of the network device 101 provided in this application embodiment is described. Figure 2 As shown, the base station provided in this application embodiment may include part 20 and part 21. Part 20 is mainly used for transmitting and receiving radio frequency signals and converting radio frequency signals to baseband signals; part 21 is mainly used for baseband processing and controlling the base station. Part 20 can generally be referred to as a transceiver unit, transceiver, transceiver circuit, or transceiver, etc. Part 21 is usually the control center of the base station and can generally be referred to as a processing unit.
[0049] The 20-part transceiver unit, also known as a transceiver or transceiver, includes an antenna and a radio frequency (RF) unit, or only an RF unit or a portion thereof. The RF unit is primarily used for RF processing. Optionally, the devices in the 20-part unit that implement the receiving function can be considered as receiving units, and the devices that implement the transmitting function can be considered as transmitting units; that is, the 20-part unit includes both receiving and transmitting units. The receiving unit can also be called a receiver, receiver circuit, or receiving device, and the transmitting unit can be called a transmitter, transmitter, or transmitting circuit.
[0050] Part 21 may include one or more single boards or chips. Each single board or chip may include one or more processors and one or more memories. The processor is used to read and execute programs in the memory to implement baseband processing functions and control the base station. If multiple single boards exist, they can be interconnected to increase processing power. As an optional implementation, multiple single boards may share one or more processors, or multiple single boards may share one or more memories. The memory and processor may be integrated or independently configured. In some embodiments, parts 20 and 21 may be integrated or independently configured. In addition, all functions in part 21 may be integrated into one chip, or some functions may be integrated into one chip while other functions may be integrated into one or more other chips. This application embodiment does not limit this.
[0051] The communication method, apparatus, electronic device, and storage medium provided in this application are applied in terminal detection scenarios. The network device can send a detection signal to the terminal. After receiving the target signal, the terminal can send a feedback signal to the network device when the target signal is a detection signal and the terminal has no network access. After receiving the feedback signal, the network device can determine to provide communication services to the target area, which is the area corresponding to the location information of the terminal. Then, the terminal can receive the access signal sent by the network device.
[0052] In combination with the above Figure 1 The communication system shown below will be described in its entirety from the perspective of the interaction between various devices in the communication system. This will illustrate the process by which the network device sends a detection signal to the terminal, and the terminal sends a feedback signal to the network device after receiving the detection signal.
[0053] like Figure 3 As shown, the communication method provided in this application embodiment may include S101-S107.
[0054] S101, The network device sends a detection signal to the terminal.
[0055] It is understandable that this detection signal is used to detect whether a terminal exists within the coverage area of the detection signal.
[0056] In this embodiment of the application, the detection signal is a common signal. The network device can select an existing common signal or design a new common signal, and then determine the existing common signal or the new common signal as the detection signal.
[0057] It should be understood that the detection signal includes an identifier for the detection signal, which is used to characterize the signal type of the detection signal. The terminal can determine the signal type of the detection signal based on the identifier of the detection signal.
[0058] Optionally, the network device may send the detection signal once at preset intervals.
[0059] Optionally, the preset duration can be 30 milliseconds.
[0060] Optionally, the detection signal can be one or more.
[0061] S102, The terminal receives the target signal sent by the network device.
[0062] It is understandable that when the terminal is within the coverage area of the target signal sent by the network device, the terminal can receive the target signal sent by the network device.
[0063] It should be noted that this target signal is a public signal.
[0064] It should be understood that the target signal can be either a public signal or an access signal.
[0065] In one implementation of this application, the terminal can perform a scan at target time intervals to detect whether there are public signals sent by network devices.
[0066] Optionally, the target duration can be 25 milliseconds.
[0067] S103. The terminal analyzes and processes the target signal to obtain the signal identifier of the target signal.
[0068] The signal identifier of the target signal corresponds to the signal type of the target signal.
[0069] It should be understood that after the terminal receives the target signal, it can parse and process the target signal to obtain the signal identifier of the target signal, and then determine the signal type of the target signal according to the correspondence.
[0070] In one alternative implementation, after receiving the target signal, the terminal can determine whether the target signal can be accessed. If the target signal cannot be accessed, the terminal can parse the target signal to obtain the signal identifier of the target signal.
[0071] S104. When the target signal is a detection signal and the terminal has no network access, the terminal sends a feedback signal to the network device.
[0072] The feedback signal includes the terminal's location information.
[0073] It should be understood that the network device may not provide communication services to the area where the terminal is located, or the communication service in the area where the terminal is located may be poor, resulting in the terminal having no network access. In the case that the terminal has no network access, the terminal can determine that it needs the network device to provide communication services.
[0074] It should be understood that when the target signal is a detection signal, it means that the detection signal is used to detect whether there is a terminal within the signal coverage area, and the detection signal cannot provide communication services to the terminal. In this case, the terminal can send a feedback signal to the network device.
[0075] Understandably, this feedback signal is used to notify the presence of a terminal in the area and that the terminal has no network access.
[0076] It should be understood that when the terminal determines that the signal type of the target signal is a detection signal and the terminal has no network access, it can send the feedback signal at the location where the terminal receives the target signal. Therefore, the feedback signal may include the location information of the terminal.
[0077] Optionally, the location information of the terminal can also be the direction in which the terminal is located, and the network device can determine the direction of the terminal based on the source of the feedback signal.
[0078] In one alternative implementation, the feedback signal can be the current uplink common signal, such as the physical random access channel (PRACH), or a newly designed common signal.
[0079] Optionally, the feedback signal may also include an identifier for the feedback signal, which may be a code identifier or a system message.
[0080] In one implementation of this application, since the network device sends the detection signal once every preset time interval, the terminal can determine the video position of the detection signal based on the time and frequency at which the terminal receives the detection signal, and send the feedback signal to the terminal based on the time-frequency position of the detection signal.
[0081] S105. When the network device receives the signal to be identified sent by the terminal, it parses and processes the signal to be identified to obtain the signal identifier of the signal to be identified and the location information of the terminal.
[0082] The signal identifier of the signal to be identified corresponds to the signal type of the signal to be identified. The identification signal is the signal sent by the terminal to the network device after receiving the detection signal.
[0083] It is understandable that when a network device receives a signal to be identified from a terminal, it means that the network device has received the signal sent by the terminal. At this time, the network device can determine the signal type of the signal to be identified.
[0084] In this embodiment of the application, the network device can receive the signal to be identified sent by the terminal at the time-frequency position of the detection signal, then parse the signal to be identified to obtain the signal identifier of the signal to be identified, and determine the signal type of the signal to be identified according to the correspondence between the signal identifier of the signal to be identified and the signal type of the signal to be identified.
[0085] Optionally, the network device may store the signal type of each of the multiple signals and the signal identifier corresponding to the signal type of each signal, and then determine the signal type of the signal to be identified based on the signal identifier of the signal to be identified.
[0086] Optionally, the network device can also analyze the signal to be identified to obtain time information, frequency information, base station service signal information, etc. If the time information of the signal to be identified is the same as the time information of the detected signal, and the frequency information of the signal to be identified is the same as the frequency information of the detected signal, the network device can analyze the signal to be identified to obtain the signal identifier of the signal to be identified, and then determine the signal type of the signal to be identified based on the signal identifier of the signal to be identified.
[0087] S106. When the signal type of the signal to be identified is a feedback signal, the network device determines to improve communication services to the target area.
[0088] The target area is the area corresponding to the location information of the terminal.
[0089] It is understandable that when the signal type of the signal to be identified is a feedback signal, it means that the signal to be identified is a signal sent by the terminal to the network device after receiving the detection signal sent by the network device. At this time, the network device can determine that the terminal exists in the area where the terminal's location information is located, and that the terminal has no network access.
[0090] It should be understood that, since the location information of the terminal exists on the terminal, the network device can determine to improve communication services to the area corresponding to the location information of the terminal.
[0091] Specifically, the network device can send an access signal to the target area so that the terminal can receive the access signal and then communicate based on the access signal.
[0092] Optionally, the network device can also direct the service beam to the target area, thereby providing communication services to the target area.
[0093] In one alternative implementation, the network device may pre-agree with the terminal on the identifier of the feedback signal, and then the network device stores the correspondence between the identifier of the feedback signal and the identifier of the detection signal. If the identifier of the target signal is the same as the identifier of the detection signal stored in the network device, the network device can determine that the signal type of the target signal is the feedback signal.
[0094] Optionally, after receiving the feedback signal sent by the terminal, the network device can determine the direction of the feedback signal's origin, and then, based on the direction of the feedback signal's origin, determine to improve communication services in that direction.
[0095] S107. The terminal receives the access signal sent by the network device.
[0096] The access signal is used to provide communication services to the terminal.
[0097] It is understandable that after receiving the access signal sent by the network device, the terminal can access the network and then communicate based on the access signal.
[0098] In one implementation of this application, the network device can send the detection signal to an area outside the coverage area of the cell corresponding to the network device based on a beam outside the cell coverage area, to detect whether there is a terminal in the area outside the coverage area of the multiple cells, and after the network device receives the feedback signal sent by the terminal outside the cell coverage area, it improves communication services to the area outside the cell coverage area.
[0099] For example, such as Figure 4As shown, area 301 is the coverage area of the cell corresponding to network device 303. Terminal 304 is located in area 302, which is outside of area 301. Network device 303 can send a detection signal to area 302. After receiving the detection signal, terminal 304 can send a feedback signal to network device 303. After receiving the feedback signal sent by terminal 304, network device 303 can determine that there is a terminal in area 303 and that the terminal in area 303 has no network access. At this time, network device 303 can send an access signal 305 to area 302, and terminal 304 can receive the access signal 305 sent by network device 303.
[0100] The technical solution provided by the above embodiments can bring at least the following beneficial effects: As shown in S101-S107, the network device can send a detection signal to the terminal, and the terminal can receive the target signal sent by the network device. When the target signal is a detection signal and the terminal has no network access, the terminal can send a feedback signal to the network device. The feedback signal includes the location information of the terminal. After receiving the feedback signal, the network device can determine to provide communication services to the target area, and then the terminal can receive the access signal sent by the network device. In this application, since the feedback signal includes the location information of the terminal, the network device can determine the target area based on the feedback signal. And since the feedback signal is sent by the terminal when it receives the detection signal and the terminal has no network access, the network device can determine that the terminal exists in the target area and that the terminal in the target area has no network service. When the terminal exists in the target area and the terminal in the target area has no network access, the network device provides communication services to the target area, which can provide network services to terminals without network service, improves the user's communication experience, and improves the flexibility of the access signal coverage.
[0101] Combination Figure 3 ,like Figure 5 As shown, the communication method provided in this application embodiment also includes S108-S109.
[0102] S108. When the signal type of the signal to be identified is other signals, the network device determines whether the signal strength of other signals is greater than or equal to the signal strength threshold.
[0103] The other signals do not include the identifier of the feedback signal.
[0104] It should be understood that if the signal type of the signal to be identified is other than a signal, the network device can determine the signal strength of the signal to be identified.
[0105] It is understandable that when the identifier of the feedback signal is not included in the signal to be identified, the network device can determine that the signal to be identified is another signal.
[0106] It is understandable that the communication environment in which the network device operates stores basic noise, and the signal strength threshold can be understood as the signal strength of this basic noise.
[0107] S109. When the signal strength of the signal to be identified is greater than or equal to the signal strength threshold, the network device determines to improve communication services to the target area.
[0108] It should be understood that if the signal strength of the signal to be identified is greater than or equal to the signal strength threshold, it indicates that the signal strength in the direction corresponding to the signal to be identified is abnormal, and there may be a terminal in the direction corresponding to the signal to be identified. In this case, the network device can also determine that it provides communication services to the target area.
[0109] Optionally, if the signal strength of the signal to be identified is less than the signal strength threshold, it indicates that the signal strength of the signal to be identified is weak. It is possible that the signal to be identified is some kind of noise interference, or that the terminal is far away from the network device. In this case, the terminal cannot receive the access signal sent by the network device, and the network device can determine that it will not provide communication services to the target area.
[0110] In one alternative implementation, after receiving the signal to be identified, the network device may be unable to parse the signal due to its weak signal strength. In this case, the network device may not parse the signal but directly determine whether the signal strength of the signal to be identified is greater than or equal to a signal strength threshold. If the signal strength of the signal to be identified is greater than or equal to the signal strength threshold, the network device may provide communication services to the target area.
[0111] Alternatively, if the network device does not perform parsing processing on the signal to be identified, the network device can determine the target area based on the direction of the source of the signal to be identified.
[0112] Combination Figure 3 ,like Figure 6 As shown, the first time-frequency position is the time-frequency position corresponding to the detection signal among multiple time-frequency positions. The network device provides communication services to the target area, which may specifically include S1061.
[0113] S1061. The network device sends an access signal to the terminal based on the second time-frequency location.
[0114] The access signal is used to provide communication services for the terminal, and the second time-frequency position is a time-frequency position other than the first time-frequency position among the plurality of time-frequency positions.
[0115] It should be understood that each public signal corresponds to a time-frequency location, and the network device can choose an unoccupied time-frequency location to send the detection signal.
[0116] It is understandable that, since the first time-frequency location is the time-frequency location corresponding to the detection signal among multiple time-frequency locations, the network device can send the access signal to the target area from other time-frequency locations besides the first time-frequency location, i.e., the second time-frequency location.
[0117] In one alternative implementation, the network device may determine the first time-frequency position or the second time-frequency position by delaying the time-frequency position of the occupied public signal by a first duration.
[0118] In another alternative implementation, the network device may involve a new common signal and identify it as the detection signal, then represent different time-frequency domain positions through different cyclic shifts.
[0119] Combination Figure 3 ,like Figure 7 As shown, the network device stores a common signal, which includes one or more of SSB, PSS and SSS, and the communication method also includes S110.
[0120] S110, network devices generate detection signals based on common signals and preset bytes.
[0121] It should be understood that SSB is a signal composed of three parts: PSS, SSS, and PBCH. The network device can determine one of the SSB, PSS, and SSS as the common signal, or it can combine one or more of the SSB, PSS, and SSS to generate the common signal.
[0122] Understandably, this preset byte serves as an identifier for the detection signal.
[0123] Optionally, the preset byte can be some system message.
[0124] Optionally, the common signal is a special PSS sequence generated by the network device using a special initial value and multiplexing the access sequence generation method. The network device can then generate the detection signal based on the special PSS sequence and the preset bytes.
[0125] In one alternative implementation, the common signal can also be a new ZC sequence, and the network device can then generate the detection signal based on the new ZC sequence and the preset bytes.
[0126] Combination Figure 3 ,like Figure 8 As shown, the communication method provided in this application embodiment also includes S111.
[0127] S111. When the target signal is an access signal and the terminal has no network access, the terminal determines to access the communication service provided by the network device based on the access signal.
[0128] It is understandable that this access signal is used to access communication services. If the terminal has no network access, it means that the terminal has not accessed communication services. In this case, if the signal type of the target signal is an access signal, the terminal can access the communication services provided by the network device based on the access signal.
[0129] It should be understood that since the terminal accesses the communication service, the terminal does not need to send the feedback signal to the network device.
[0130] Combination Figure 3 ,like Figure 9 As shown, the terminal sends a feedback signal to the network device, which may specifically include S1041.
[0131] S1041. The terminal sends a feedback signal to the network device based on the first time-frequency location.
[0132] The first time-frequency position is the time-frequency position corresponding to the detection signal among multiple time-frequency positions.
[0133] Based on the description of the above embodiments, it should be understood that the first time-frequency position is the time-frequency position corresponding to the detection signal among multiple time-frequency positions. After receiving the detection signal sent by the network device, the terminal parses the detection signal to obtain the time-frequency position of the detection signal. Then, the terminal can send a feedback signal to the network device based on the first time-frequency position.
[0134] In this embodiment, the terminal sends the feedback signal to the network device based on the time-frequency position corresponding to the detection signal, which can ensure that the network device can receive the feedback signal and improve the effectiveness of the feedback signal transmission. After the network device receives the feedback signal based on the first time-frequency position, the network device can determine that the feedback signal is the signal sent by the terminal after receiving the detection signal, which can effectively realize the signal interaction between the network device and the terminal.
