However, it should be understood that the drawings and their detailed descriptions do not limit the embodiments to any particular form of this disclosure, but rather include all modifications, equivalents, and alternative forms that fall within the essence and scope of the claims. [Modes for carrying out the invention]

[0016] The following describes typical applications in various aspects of the apparatus and methods described herein. These examples are provided solely to add context and aid in understanding the embodiments described. Therefore, it will be apparent to those skilled in the art that the embodiments described below can be implemented without some or all of the specific details. In other cases, well-known process steps are not described in detail to avoid unnecessarily obscuring the embodiments described. Other applications are possible, and the solutions of the disclosure are not limited to these examples.

[0017] Typically, a wireless communication system includes at least a transmitting end device and a receiving end device. The transmitting end device and the receiving end may be either control equipment (e.g., base station control) or terminal equipment. In particular, both the transmitting end device and the receiving end device may be terminal equipment.

[0018] In this disclosure, the terms “base station” or “control equipment” have the full scope of their ordinary meaning and include radio stations that are at least part of a radio communication system or radio system in order to perform communications. Examples of base stations may be, for example, eNBs for 4G communication standards, gNBs for 5G NR communication standards, remote radio heads, radio access points, drone control towers, or communication devices that perform similar functions. In this disclosure, “base station” and “control equipment” are interchangeable, or “control equipment” may be implemented as part of a “base station.” The following describes in detail examples of base station / terminal equipment applications, with reference to the drawings, using base stations as an example.

[0019] In this disclosure, the terms “Terminal Equipment” or “User Equipment (UE)” have the full scope of their ordinary meaning and include terminal equipment that is at least part of a wireless communication system or radio system for communication purposes. For example, terminal equipment may be terminal equipment or components thereof such as a mobile phone, laptop computer, tablet computer, in-vehicle communication equipment, wearable device, or sensor. In this disclosure, “Terminal Equipment” and “User Equipment” (which may be abbreviated as “UE”) are interchangeable, or “Terminal Equipment” may be implemented as part of “User Equipment”.

[0020] In this disclosure, the terms “core network equipment” or “core network entity” have the full scope of their ordinary meaning and may refer to network element equipment that provides one or more core network functions, or, where appropriate, software and / or hardware modules that provide one or more core network functions. In particular, when they share the responsibility of providing one or more core network functions, “core network equipment” or “core network entity” may refer collectively to these devices and / or modules that realize one or more functions. Hereinafter, “core network equipment” or “core network entity” may be abbreviated as “core network.”

[0021] In this disclosure, the term “transmitting end” has the full scope of its usual meaning and typically refers to the side that transmits data in a communication system, which may be the control equipment / base station side or the terminal equipment / UE side. Similarly, the term “receiving end” has the full scope of its usual meaning and accordingly refers to the side that receives data in a communication system, which may be the terminal equipment / UE side or the control equipment / base station side. In this disclosure, the same equipment may serve as both the transmitting end and the receiving end.

[0022] In this disclosure, the terms “uplink” or “uplink communication link” typically refer to a transmission link from the transmitting end to the receiving end, and the terms “downlink” or “downlink communication link” typically refer to a transmission link from the receiving end to the transmitting end.

[0023] As introduced in the background technology section, with the development of wireless communication technology and the evolution of demand, wireless communication application scenarios that require both communication and sensing functions are increasingly emerging.

[0024] Figure 1 shows several exemplary application scenarios for communication sensing integration. As shown in Figure 1, these application scenarios may include smart manufacturing and industrial Internet of Things supporting predictive maintenance, automated guided vehicles, employee location and authorization, environmental monitoring supporting weather forecasting, pollutant monitoring, rainfall monitoring, insect detection, etc., sensing as a service supporting mobile crowd sensing, drone monitoring and management, channel knowledge map building, cooperative positioning and imaging, etc., remote sensing supporting satellite and imaging broadcasting, drone synthetic aperture radar (SAR) imaging, etc., smart homes supporting human proximity detection, spatial sensing control, life signal monitoring, fall detection, sensing-assisted wireless charging, etc., human-computer interaction supporting gesture recognition, head / arm motion recognition, key identification, etc., and V2X supporting high-precision positioning, extended sensors, secure access, simultaneous positioning and mapping, etc. In these exemplary application scenarios, information may be transmitted by communication between two or more entities. The entities may also transmit sensing signals at the same time as they communicate. This allows for the detection of the state and characteristics of things in the environment, such as detecting humidity, pollutants, insects, etc., or detecting the presence and / or distance of specific objects or obstacles within a specific area.

[0025] For example, depending on the sensing signal processing node, sensing may be divided into transmit-end active sensing, receive-end active sensing, or joint sensing by the transmit-end and receive-end. In the case of receive-end active sensing, the transmit-end may transmit a sensing signal to the sensing target as the receive-end. The receive-end may receive the sensing signal (for example, by determining that the sensing signal is a sensing signal for itself), process the received sensing signal, and obtain sensing information. Additionally, the receive-end may report the processed sensing information to a control device of the wireless network or a network element responsible for sensing in the core network for further processing. In this disclosure, a beam that carries a sensing signal is called a sensing beam, and a beam that carries a communication signal is called a communication beam.

[0026] In the case of transmit-end active sensing, sensing may be performed transparently to the target being sensed. For example, the transmit end may obtain sensing information by processing echo signals generated by reflection / scattering / diffraction of the signal transmitted by the transmit end by the sensing target. For example, the echo signal of a communication signal may be used directly for sensing. However, because communication beams are highly directional, the beam reception gain is too small for targets not located in the direction of the communication beam, making detection difficult. Therefore, according to this disclosure, the transmit end can perform sensing by transmitting a signal (i.e., a sensing signal) that can cover a wider directional range. Figure 2A illustrates the relationship between the sensing beam and the communication beam in the communication sensing integrated system according to this disclosure. As shown in Figure 2A, the sensing beam can cover a wider range than the communication beam by scanning, but may be a beam directed at a sensing target that is closer in distance than the communication target. In this disclosure, the sensing beam can cover the entire sensing region by narrow-beam scanning. For example, each time a sensing signal is transmitted, the transmitting end may use one of several sensing beams corresponding to multiple directions to transmit the sensing signal, and then switch to a different sensing beam when transmitting the next sensing signal. The following description will use the case where the transmitting end uses one sensing beam at a time to transmit the sensing signal as an example. However, this disclosure is not limited to such a scanning method of sensing beams, and for example, if the transmitting end has multiple radio frequency modules, the transmitting end may use multiple sensing beams simultaneously to transmit the sensing signal. Here, each radio frequency module uses one sensing beam to transmit the sensing signal.

[0027] Figure 2B shows an exemplary communication sensing integration application that utilizes the echo of a sensing signal to perform sensing, to which the technology of this disclosure can be applied. As shown in Figure 2A, the communication sensing integration system can be used in a vehicle-to-vehicle (V2V) communication scenario. In a V2V communication scenario, vehicles can communicate with each other to transmit information such as vehicle speed, location, and road conditions. Each vehicle can also sense any object that may affect driving, such as pedestrians, obstacles, or other vehicles around the vehicle, by transmitting a sensing signal. The object as a sensing target may generate an echo signal simply by physically reflecting / refracting / diffracting the sensing signal. For example, the position and speed of the sensing target may be sensed by comparing the difference between the sensing signal and the echo signal.

[0028] In the case of joint sensing between a transmitting and receiving end, the transmitting end may obtain sensing information by processing the echo signal of the sensing signal, and the receiving end may obtain sensing information by processing the received sensing signal. The transmitting end, the receiving end, or other network elements in the wireless network (for example, network elements responsible for sensing in the core network) may comprehensively process the information obtained by the transmitting end based on the echo signal and the information obtained by the receiving end based on the sensing signal to obtain final sensing information.

[0029] The communication sensing integrated system described herein may be considered based on the following assumptions: 1. The communication sensing integrated system includes a communication module and an active radar module, both of which can share transmitting end hardware equipment and time-frequency resources; 2. The transmitter can transmit communication and sensing beams simultaneously or non-simultaneously; 3. The communication receiving end is located in a remote location, and the radar receiving end is located near the transmitting end, and it is assumed that the antenna positions of the transmitting end transmitter and the radar receiver are approximately the same.

[0030] The communication signal model and the sensing signal model applied to the communication sensing integration system according to the present disclosure will be briefly introduced below.

[0031] (Communication signal model) Regarding the communication module in the communication sensing integration system, assume that the application scenario is a millimeter-wave multipath channel. Figure 3 shows a typical multipath channel, where Tx is the transmitter, Rx is the receiver. As the transmitter, a half-wavelength equally spaced linear array antenna (Uniform Linear Array, ULA) is used, and the number of antennas is denoted as N T and the receiver is a single antenna. The channel from the transmitter to the receiver is denoted as h (h is a 1×N T dimensional vector), a single line-of-sight path (Line of Sight, LoS) h0 (h0 is a 1×N T dimensional vector), and P non-line-of-sight paths (Non Line of Sight, NLoS) h k (h k is a 1×N T dimensional vector), where k = 1, …, P. The attenuation coefficient of the path h k is denoted as γ k , k = 0, 1, …, P (γ k is a complex number), and the multipath channel h is

Equation

[0032] If the angle of departure (AoD) of the k-th path is θ k (AoD) , then the k-th path is

Equation

[0033] Here,

Equation

[0034] The precoding vectors used for communication and sensing are f c (f c is one N T (which is a 1-dimensional vector) and f s (f s is one N T (This is a 1-dimensional vector), and the communication signal and sensing signal to be carried are respectively s c (s c (where is a complex number) and s s (s s If we denote it as (where y is a complex number), then the user received signal y (where y is a complex number) is,

number

[0035] Here, the first term is the communication signal, the second term is interference due to the sensing signal, and the third term is noise. Below, q c =h H f c If written as, |q c | 2 is the communication beamforming gain, and q s =h H f s If written as, |q s | 2 This is the sensing signal interference power.

[0036] (Sensing signal model) For sensing modules in a communication sensing integrated system, it is conceivable to use a modulation technique compatible with communication. To facilitate the description of the sensing signal model, orthogonal frequency division multiplexing (OFDM) is used here, and for example, an OFDM signal is used to sense the distance and velocity of the sensing target. However, this disclosure is not limited to OFDM, and it should be understood that any modulation technique compatible with communication can be used. The coherent processing interval is Nsym It contains OFDM symbols, and the duration of one OFDM symbol is T OFDM And N c It contains n subcarrier signals, the subcarrier interval is Δf, and in the μth OFDM symbol being transmitted, the signal transmitted on the nth subcarrier is s[μ,n] μ=0,1,…,N sym -1, n=0,1,…,N c Assume the value is -1. The number of transmitter antennas is N. T The transmitted steering vector used is f (where f is one N T Assume the vector is ×1 and the receiver receives using an omnidirectional single antenna. Assume there are k sensing targets in the environment, and the aliasing delay time of each sensing target signal is all within the cyclic prefix. Assume the channel between the transmitter and the kth sensing target object is h k (h k is one N T (which is a vector of ×1), the attenuation and reflection coefficients are A k (A k (where R is a complex number), the distance to the target object is R k And the Doppler shift is f D,k In this case, the echo signal y of the OFDM signal received after being reflected by the sensing target is k [μ,n] is,

number

[0037] Here, the Doppler shift is f D,k =2ν rel f c / c0 and ν rel f is the radial relative velocity between the transmitting end radar and the sensing target. c c0 is the carrier frequency, and c0 is the speed of light. Echo signals reflected from all sensing targets in the environment are superimposed to form the final received signal received by the transmitting end radar.

[0038]

number

[0039] By meshing the distance-Doppler shift parameters and performing related processing, a distance-Doppler phase diagram detected by the radar can be obtained. k H f is the detection gain by the transmitting end beam; the higher the detection gain, the easier it is to identify the target in the phase diagram. The mathematical expression for the phase diagram is:

number

[0040] Here, conj(s[μ,n]) represents the conjugate of s[μ,n].

[0041] For simplicity, the sensing signal model described above only considers echo signals resulting from reflection of the sensing signal by the sensing target. In practice, echo signals resulting from reflection, refraction, diffraction, or a combination thereof by the sensing target may also be considered.

[0042] In integrated communication and sensing systems, both communication signals and sensing signals are present, so it is crucial to ensure that the receiving end correctly receives the desired signal.

[0043] Figure 4 illustrates a conceptual operation flow according to an embodiment of the present disclosure.

[0044] As shown in Figure 4, according to this disclosure, a transmitting end can instruct a receiving end with control information regarding the transmission of communication signals and sensing signals. The receiving end can receive and / or process the communication signals and / or sensing signals in accordance with the control information. The control information according to this disclosure may include any information necessary for the receiving end to receive and / or process the communication signals and / or sensing signals, such as information indicating the sensing beam arrangement, which is described in detail below, information indicating the transmission mode, duration information, information indicating at least one parameter for eliminating interference from the sensing signals to the communication signals, and any other appropriate information. According to this disclosure, the transmitting end may explicitly instruct the receiving end with control information; for example, the transmitting end may transmit control information to the receiving end. Alternatively, the transmitting end may instruct the control information at least partially implicitly. For example, at least some of the control information may be pre-promised or predetermined by relevant standards, i.e., at least some of the control information may be default. Furthermore, the transmitting end may explicitly send additional control information to the receiving end based on some default control information, so that the receiving end can integrate all the instructed control information and receive and / or process communication signals and / or sensing signals. According to this disclosure, at least some of the control information may be transmitted using any appropriate signaling and / or messages, for example, via RRC signaling or MAC CE.

[0045] Figure 5 illustrates a conceptual arrangement of electronic equipment on the transmitting end device side according to an embodiment of the present disclosure.

[0046] As shown in Figure 5, the electronic device 10 may include a processing circuit 102. The processing circuit 102 may be configured to instruct the receiving end electronic device on the control information relating to the transmission of communication signals and sensing signals so that the receiving end electronic device can receive and / or process communication signals and / or sensing signals in accordance with the control information.

[0047] The processing circuit 102 may be in the form of a general-purpose processor or a dedicated processing circuit such as an ASIC. For example, the processing circuit 102 may be composed of a circuit (hardware) or a central processing unit (e.g., a central processing unit (CPU)). The processing circuit 102 may also contain a program (software) for operating the circuit (hardware) or the central processing unit. This program may be stored in memory (e.g., set in memory 104), or in an externally connected storage medium, or it may be downloaded via a network (e.g., the Internet).

[0048] In one embodiment, the processing circuit 102 may include a control information determination unit. This control information determination unit can determine control information to be instructed to the receiving end electronic device. For example, the control information determination unit may determine sensing beam arrangement information. Alternatively, for example, the control information determination unit may determine the transmission modes of the communication signal and the sensing signal. Alternatively, for example, the control information determination unit may determine the duration of the transmission modes of the communication signal and the sensing signal. Alternatively, for example, the control information determination unit may determine information necessary for the receiving end electronic device to perform interference rejection on the received information.

[0049] In one embodiment, the processing circuit 102 may further include a sensing control unit. The sensing control unit may, for example, arrange sensing signals based on sensing signal arrangement information and control the system to perform sensing using the sensing signals.

[0050] Selectively, the electronic device 10 may further include a memory 104, shown by a dotted line in the figure, and a communication unit 106. The electronic device 10 may also include other components not shown, such as a radio frequency link, a baseband processing unit, a network interface, a processor, and a controller. The processing circuit 102 may be associated with the memory 104 and / or the communication unit 106. For example, to access data, the processing circuit 102 may be directly or indirectly connected to the memory 104 (for example, with other components connected in between). Alternatively, for example, the processing circuit 102 may be directly or indirectly connected to the communication unit 106. This allows for the transmission and reception of radio signals via the communication unit 106.

[0051] Memory 104 can store various information determined and / or generated by the processing circuit 102 (e.g., control information related to the transmission of communication signals and sensing signals, sensing beam arrangement, etc.), programs and data used for the operation of the electronic device 10, data transmitted by the communication unit 106, and so on. Memory 104 can be located inside the processing circuit 102 or outside the electronic device 10, and is therefore depicted with a dashed line. Memory 104 may be volatile memory and / or non-volatile memory. For example, memory 104 may include, but is not limited to, random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), read-only memory (ROM), and flash memory.

[0052] The communication unit 106 may be configured to communicate with terminal equipment under the control of the processing circuit 102. In one example, the communication unit 106 may be implemented as a transmitter or transceiver including communication components such as an antenna array and / or a radio frequency link.

[0053] Figure 5 shows that the processing circuit 102 is separated from the communication unit 106, but the processing circuit 102 may be implemented to include the communication unit 106. For example, it may be implemented in combination with the communication control unit. The processing circuit 102 may also be implemented to include one or more other components in the electronic device 10, or the processing circuit 102 may be implemented as the electronic device 10 itself. In actual implementation, the processing circuit 102 may be implemented as a chip (e.g., an integrated circuit module including a single chip), a hardware component, or a complete product.

[0054] Figure 6 illustrates a conceptual arrangement of electronic equipment on the receiving end device side according to an embodiment of the present disclosure.

[0055] As shown in Figure 6, the electronic device 20 may include a processing circuit 202. The processing circuit 202 may be configured to receive and / or process communication signals and / or sensing signals in accordance with control information regarding the transmission of communication signals and sensing signals, as instructed by the transmitting end electronic device (e.g., electronic device 10).

[0056] The processing circuit 202 may be in the form of a general-purpose processor or a dedicated processing circuit such as an ASIC. For example, the processing circuit 202 may be composed of a circuit (hardware) or a central processing unit (e.g., a central processing unit (CPU)). The processing circuit 202 may also contain a program (software) for operating the circuit (hardware) or the central processing unit. This program may be stored in memory (e.g., set in memory 204), or on an externally connected storage medium, or it may be downloaded via a network (e.g., the Internet).

[0057] In one embodiment, the processing circuit 202 may include a control information determination unit. The control information determination unit may determine the information necessary to receive and / or process communication signals and / or sensing signals in accordance with the information instructed by the transmitting end electronic equipment. For example, the control information determination unit may determine the transmission modes of the communication signals and sensing signals. Alternatively, for example, the control information determination unit may determine the duration of the transmission modes of the communication signals and sensing signals. Alternatively, for example, the control information determination unit may determine the information necessary for the receiving end electronic equipment to perform interference rejection on the received information. Alternatively, for example, the control information determination unit may determine the arrangement of the sensing signals.

[0058] In one embodiment, the processing circuit 202 may further include an interference control unit. The interference control unit may, for example, perform interference removal processing on the received signal. The interference control unit may also, for example, perform interference measurement on the received information and additionally transmit the interference measurement results to the communication unit 206, for example, to the transmitting end electronic equipment.

[0059] Selectively, the electronic device 20 may further include a memory 204, shown by a dotted line in the figure, and a communication unit 206. The electronic device 20 may also include other components not shown, such as a radio frequency link, a baseband processing unit, a network interface, a processor, and a controller. The processing circuit 202 may be associated with the memory 204 and / or the communication unit 206. For example, to access data, the processing circuit 202 may be directly or indirectly connected to the memory 204 (for example, with other components connected in between). Alternatively, for example, the processing circuit 202 may be directly or indirectly connected to the communication unit 206. This allows for the transmission and reception of radio signals via the communication unit 206.

[0060] Memory 204 can store various information determined and / or generated by the processing circuit 202 (e.g., control information related to the transmission of communication signals and sensing signals, interference intensity information, etc.), programs and data used for the operation of the electronic device 20, data transmitted by the communication unit 206, etc. Memory 204 can be located inside the processing circuit 202 or outside the electronic device 20, and is therefore depicted with a dashed line.

For example, memory 204 may include, but is not limited to, random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), read-only memory (ROM), and flash memory.

[0061] The communication unit 206 may be configured to communicate with terminal equipment under the control of the processing circuit 202. In one example, the communication unit 206 may be implemented as a transmitter or transceiver including communication components such as an antenna array and / or a radio frequency link.

[0062] Figure 6 shows that the processing circuit 202 is separated from the communication unit 206, but the processing circuit 202 may be implemented to include the communication unit 206. For example, it may be implemented in combination with a communication control unit. The processing circuit 202 may also be implemented to include one or more other components in the electronic device 20, or the processing circuit 202 may be implemented as the electronic device 20 itself. In actual implementation, the processing circuit 202 may be implemented as a chip (e.g., an integrated circuit module including a single chip), a hardware component, or a complete product.

[0063] In the explanation given with reference to Figures 5 and 6, the above units are merely logic modules categorized based on the specific functions they realize, and do not restrict the specific implementation method. For example, they may be implemented in software, hardware, or a combination of software and hardware. When actually implemented, each of the above units may be implemented as an independent physical entity, or by a single entity (e.g., a processor (CPU or DSP, etc.), an integrated circuit, etc.). The dashed lines in the figures indicate that these units do not necessarily have to exist in reality, and the operations / functions they realize may be implemented by the processing circuit itself.

[0064] The communication sensing integration system of this disclosure can be applied to various communication scenarios, for example, to communication between conventional control equipment (e.g., base stations) and terminal equipment, or for example, to sidelink communication. According to this disclosure, the electronic device 10 as the transmitting end device may be a control device for wireless communication, and the electronic device 20 as the transmitting end device may be a terminal device for wireless communication. Alternatively, the electronic device 10 as the transmitting end device may be a terminal device for wireless communication, and the electronic device 20 as the transmitting end device may be a control device for wireless communication. Both the electronic device 10 and the electronic device 20 as the transmitting end device may be terminal devices for wireless communication.

[0065] The communication sensing integration system of this disclosure can be applied to various sensing methods, for example, to transmitter-end active sensing, receiver-end active sensing, or joint sensing of both the transmitter and receiver.

For example, sensing capabilities may include the scanning range of the sensing beams supported by the transmitter, the method and parameters for generating the sensing sequence of the sensing signal, the number of sensing beams that can be emitted simultaneously (for example, if the transmitter has multiple radio frequency modules for emitting multiple beams simultaneously), and any other capabilities necessary for the transmitter to participate in sensing. According to this disclosure, the control equipment of the radio communication can transmit information indicating the sensing beam arrangement to the transmitter. For example, the sensing beam arrangement may be determined by the control equipment of the radio communication or a network element responsible for sensing in the core network based on the sensing capabilities of the transmitter. For example, the transmitter may determine the sensing beam arrangement itself and, if necessary, report the sensing beam arrangement to the control equipment of the radio communication or a network element responsible for sensing in the core network. For example, the transmitting end may arrange one or more beams for transmitting sensing signals according to sensing beam arrangement information. For example, the sensing beam arrangement may include sensing sequence generation method and parameters, sensing signal transmission method, sensing signal resource mapping rules, sensing service start and end times, etc. For example, wireless communication control equipment may transmit information indicating the sensing beam arrangement to the transmitting end using any applicable signaling / message (e.g., Radio Resource Control (RRC) signaling or Media Access Control Control Element (MAC CE)). Alternatively, information regarding the arrangement of at least some sensing beams may be predetermined or specified in the relevant standards.

[0066] When the receiving end participates in sensing (e.g., receiving end active sensing or joint sensing by the transmitting and receiving ends), the transmitting end or the control equipment for the radio communication may transmit sensing beam arrangement information to the receiving end so that the receiving end can receive and / or process sensing signals. For example, sensing beam arrangement information may be transmitted to the receiving end using any applicable signaling / message (e.g., RRC signaling or MAC CE). For example, sensing beam arrangement information received by the receiving end from the transmitting end may be the same as, or further determined based on, information received by the transmitting end from the control equipment. For example, the transmitting end may select one of several selective sensing beam arrangements transmitted by the control equipment to arrange the sensing beam. Alternatively, for example, the transmitting end may transmit to the receiving end some of the sensing beam arrangement information that the receiving end needs to process the sensing signals it receives. Alternatively, for example, the transmitting end may transmit multiple sensing beam arrangements to the receiving end for use in multiple cases. In this case, the correspondence between the sensing beam arrangement and the application status may be predetermined, determined, indicated by the transmitting end or control equipment, or selected by the receiving end.

[0067] If the receiving end participates in sensing, it may process the sensing signal according to information indicating the sensing beam arrangement. For example, the receiving end may determine the angular direction, distance, and relative velocity of the transmitting end or environmental sensing target based on the intensity, phase rotation, frequency offset, and delay of the sensing signal. Alternatively, for example, the receiving end may simply determine the intensity, phase rotation, frequency offset, and delay of the sensing signal, and transmit the determined results to a wireless communication control device or a network element responsible for sensing in the core network, where it may perform more complex processing to determine further sensing information.

[0068] In the communication sensing integrated system of this disclosure, since both communication signals and sensing signals are present, the receiving end needs to know how these two types of signals are transmitted, for example, whether they are transmitted individually or simultaneously. Accordingly, according to this disclosure, the control information regarding the transmission of communication signals and sensing signals instructed from the transmitting end to the receiving end, as shown in Figure 4, may include information indicating the transmission mode of the communication signals and sensing signals, where the transmission mode includes one of the following: a first mode in which the communication signals and sensing signals are transmitted using the same time-frequency resources; a second mode in which only the communication signals are transmitted using a single time-frequency resource; and a third mode in which only the sensing signals are transmitted using a single time-frequency resource.

[0069] Figure 7 illustrates the transmission modes of communication signals and sensing signals according to embodiments of the present disclosure. As shown in Figure 7, Mode 1 (i.e., the first mode described above) may transmit both communication signals and sensing signals using the same time-frequency resources. For example, both communication signals and sensing signals may be transmitted using the same time and frequency resources, utilizing different beams. In Mode 1, since the communication signals and sensing signals are transmitted superimposed, the utilization rate of time-frequency resources can be effectively improved, and since the transmission of sensing signals does not occupy the available frequency / time for communication signals, Mode 1 does not degrade communication performance, especially compared to conventional methods of time-division / frequency-division multiplexing of sensing signals and communication signals. Mode 2 (i.e., the second mode described above) may transmit only communication signals using a single time-frequency resource. In Mode 2, all available time-frequency resources at the transmitting end may be used for transmitting communication signals. In other words, in Mode 2, sensing remains muted, i.e., no sensing signals are transmitted. Mode 3 (i.e., the third mode described above) may transmit only the sensing signal using a single time-frequency resource. In Mode 3, all available time-frequency resources at the transmitting end may be used to transmit the sensing signal. In other words, in Mode 3, communication remains muted, i.e., no communication signal is transmitted. Three transmission modes are shown in Figure 7, but this disclosure is not limited to the transmission modes listed. For example, there may be further transmission modes that multiplex communication signals and sensing signals using different time-frequency resources.

[0070] According to this disclosure, the transmitting end can implicitly or explicitly instruct the receiving end on the transmission mode. For example, the transmitting end may transmit information indicating the transmission mode to the receiving end. Alternatively, for example, if the transmission mode is predetermined or default, the transmitting end may implicitly instruct the receiving end on the transmission mode to be adopted while simultaneously transmitting further information indicating the transmission mode to the receiving end. For example, control information relating to the transmission of communication signals and sensing signals may include duration information. If the transmission mode is explicitly instructed, the duration information may be the duration of the instructed transmission mode. Alternatively, if the transmission mode is implicitly instructed, the duration information may indicate one of the following: the duration for which communication signals and sensing signals are transmitted using the same time-frequency resource; the duration for which only communication signals are transmitted using a single time-frequency resource; or the duration for which only sensing signals are transmitted using a single time-frequency resource. For example, if a predetermined or default transmission mode is adopted, the transmitting end may transmit only duration information indicating the duration of the predetermined or default transmission mode to the receiving end, without explicitly transmitting information indicating the transmission mode. Alternatively, the duration information may indicate the duration for which a predetermined or default transmission mode is paused.

[0071] According to this disclosure, the duration of the transmission mode may be indicated in any applicable time unit. For example, the duration information may include the number of slots, the number of symbols, a specific time (e.g., seconds), etc.

[0072] According to this disclosure, the transmission mode may be predetermined (for example, a default transmission mode may be specified in the relevant standard), or it may be determined by the transmitting end, or optionally by the control equipment, and notified to the receiving end. For example, the transmission mode may be determined based on the interference intensity of the communication signal by at least the sensing beam being used. Possible interference by the sensing beam on the communication signal is briefly described below.

[0073] Due to various factors such as sidelobe leakage, clutter noise, and multipath effects, sensing signals can interfere with communication signals to varying degrees. Figure 8 illustrates an example of interference by a sensing beam with a communication beam.

[0074] In Figure 8, the hatched blocks may represent an obstacle in the multipath channel (e.g., a building, a mountain, etc.). The sensing beam may be refracted by the obstacle, causing multipath propagation of the sensing signal. This depends on the angle of refraction between the sensing beam and the obstacle. The refracted sensing signal may cause strong or weak interference to the communication signal. For example, the left diagram in Figure 8 shows a weak interference case, while the right diagram in Figure 8 shows a strong interference case. In Figure 8, the sensing beam below the communication beam also interferes with the communication signal due to reasons such as sidelobe leakage and clutter noise.

[0075] Generally, both sensing beams and communication beams are highly directional, so interference from sidelobe leakage and clutter noise is usually weak for most sensing beams. Furthermore, in typical communication environments, due to multipath effects, it is relatively rare for sensing signals to enter the communication receiving end through strong paths. Therefore, interference from sensing signals to communication signals is generally weak, and strong interference from sensing signals to communication signals only occurs for relatively short periods or with sensing beams in specific directions.

[0076] In view of the interference situation between the sensing beam and the communication beam described above, the transmitting end according to this disclosure divides a plurality of sensing beams (for example, a plurality of beams corresponding to the sensing scanning area described above) into a strongly interfering sensing beam and a weakly interfering sensing beam, determines the transmission mode used for the weakly interfering sensing beam as the first mode, and the transmitting end may further determine the transmission mode used for the strongly interfering sensing beam as the second mode or the third mode based on the priority between communication and sensing. For example, the priority may be related to the importance and urgency of the sensing service and the communication service. For example, if the priority of the communication service is higher than the priority of the sensing service, the mode used for the strongly interfering sensing beam may be determined as the second mode, and if the priority of the sensing service is higher than the priority of the communication service, the mode used for the strongly interfering sensing beam may be determined as the third mode. In particular, if some of the multiple beams corresponding to the sensing scanning area are highly interfering beams, and the priority of the communication service is higher than the priority of the sensing service, the first mode may be used, and sensing may be performed without using the sensing beams determined to be highly interfering, that is, sensing in the direction corresponding to the highly interfering beams may be temporarily suspended.

[0077] Specifically, for example, during the beam training phase, the receiving end may train each beam (including each communication beam and sensing beam) by measuring a reference signal (e.g., a synchronization signal block (SSB)) to obtain the intensity gain of each beam. This allows the receiving end to separate multiple sensing beams into strongly interfering beams and weakly interfering beams according to an interference intensity threshold. For example, the interference intensity threshold may be a predetermined percentage of the intensity gain of the communication beam with the highest intensity measured by the receiving end. The receiving end may, for example, separate sensing beams with an intensity gain higher than the interference intensity threshold into strongly interfering beams and sensing beams with an intensity gain below the interference intensity threshold into weakly interfering beams, and then feed this information back to the transmitting end. In subsequent communications, the receiving end may feed back feedback information regarding the interference intensity of the sensing beams to the transmitting end, and the transmitting end may dynamically adjust the classification of strongly interfering sensing beams and weakly interfering sensing beams according to the feedback information from the receiving end.

[0078] For example, the receiving end may perform the interference measurement and feedback method according to the Disclosure to determine the interference intensity of the sensing beam to the communication beam and provide feedback to the transmitting end as needed. Figure 9 shows an exemplary interference measurement and feedback method 90 according to the Disclosure.

[0079] As shown in Figure 9, the receiving end first receives the communication signal and sensing signal transmitted in mode 1 in S902. In S904, the receiving end attempts to demodulate the communication signal directly without any additional processing. Here, "without any additional processing" can be interpreted as the receiving end demodulating the communication signal directly, as if the sensing signal did not exist, according to the processing method in a normal communication sensing non-integrated scenario. If the receiving end successfully demodulates the communication signal in S904, in S916, the receiving end may selectively label the sensing beam corresponding to this transmission as a weakly interfering beam and feed this back to the transmitting end. Alternatively, after successfully demodulating the communication signal, the receiving end may simply label the interference strength of the sensing beam without feeding it back to the transmitting end. In this case, if the transmitting end has not received feedback from the receiving end regarding the interference strength of the sensing beam, and has not received feedback from the transmitting end regarding the failure to receive this communication signal, it maintains that the sensing beam is a weakly interfering beam.

[0080] If the receiving end fails to successfully demodulate the communication signal in S904, the receiving end may label the sensing beam corresponding to this transmission as a strongly interfering beam in S912 and feed this back to the transmitting end. Selectively, the receiving end may perform interference rejection on the received signal in S906. Specific interference rejection methods will be described in detail later. If the communication signal still cannot be properly demodulated in S908 after interference rejection, the receiving end may label the sensing beam corresponding to this transmission as a strongly interfering beam in S912 and feed this back to the transmitting end. Selectively, the receiving end may request a reference signal from the transmitting end in S910 to perform a more accurate interference measurement. For example, the reference signal may be Channel State Information-Interference Measurement (CIS-IM). For example, the receiving end may determine the interference intensity of the sensing beam on the communication signal in response to the CSI-IM interference measurement performed in S910, and based on a comparison of the measured interference intensity with a predetermined threshold, label the sensing beam as strongly interfering (e.g., interference intensity is greater than the predetermined threshold) or weakly interfering (e.g., interference intensity is less than or equal to the predetermined threshold), and provide feedback to the transmitting end accordingly. For example, to perform finer control, the predetermined threshold may preferably be smaller than the interference intensity threshold at which the transmitting end first classifies the sensing beam.

[0081] If the communication signal is correctly demodulated in S908 after interference rejection, the receiving end preferably determines in S914 whether the sensing beam gain obtained in the interference rejection stage (for example, which can indicate the interference intensity of the sensing beam on the communication signal) exceeds a predetermined threshold (for example, to perform finer control, the predetermined threshold may preferably be smaller than the interference intensity threshold at which the transmitting end first divides the sensing beam). If the sensing beam gain is greater than the predetermined threshold, the receiving end executes step S912 described above. Alternatively, before S912, step S910 described above may be executed. If the sensing beam gain does not exceed the predetermined threshold, the sensing beam may be labeled as a weakly interfering beam and selectively fed back to the transmitting end.

[0082] By employing the interference measurement method 90 shown in Figure 9, a weakly interfering sensing beam can be dynamically adjusted to a strongly interfering beam based on feedback from the receiving end. The receiving end may also perform interference measurements by periodically, semi-periodicly, or semi-sustainably requesting a reference signal for the strongly interfering sensing beam. This allows for adjustment to a weakly interfering beam when the degree of interference of these sensing beams changes. For example, the reference signal may be CIS-IM. Alternatively, the receiving end may perform interference measurements by periodically, semi-periodicly, or semi-sustainably requesting a reference signal for each sensing beam (regardless of the strength of its interference). This allows for detection and feedback of changes in the degree of interference of these sensing beams. For example, selectively, interference measurements based on a reference signal may include interference power measurements that measure only the interference power intensity, interference channel measurements that measure the equivalent channel in interference beamforming, etc.

[0083] The integrated communication sensing system of this disclosure may involve switching between different transmission modes (for example, using different transmission modes for different sensing beams). Special settings may be made for the order in which transmission modes are used (in other words, the beam scanning order). This avoids increased signaling overhead due to excessive switching of transmission modes. For example, the transmitting end may transmit a sensing signal using multiple sensing beams corresponding to multiple directions by scanning, and skip one or more sensing beams corresponding to the sensing signal transmitted in the third mode in each round of scanning, and after a single downlink transmission used for the communication signal is completed, transmit the sensing signal in the third mode using the skipped one or more sensing beams.

[0084] Figure 10 illustrates an exemplary setting for the scanning sequence of the sensing beam according to an embodiment of the present disclosure. The upper part of Figure 10 shows the transmission method of the communication signal and sensing signal when following a normal scanning method (i.e., sequentially scanning each beam in the sensing region clockwise or counterclockwise). As shown in the upper part of Figure 10, if the sensing signal has a high priority and the sensing beam at an intermediate position in the scanning sequence strongly interferes with the communication signal, the transmitting end must first transmit in mode 1, and when it encounters a strongly interfering sensing beam, it must temporarily suspend the transmission of the communication signal, switch to mode 3, and transmit only the sensing signal, and then, when the sensing beam becomes a weakly interfering beam, switch back to mode 1 and transmit both the communication signal and the sensing beam. Switching transmission modes leads to extra signaling overhead and a decrease in communication efficiency. Furthermore, if the strongly interfering sensing beams are not arranged sequentially in a clockwise or counterclockwise order, such switching becomes more frequent, which can even result in unacceptable signaling overhead and low communication efficiency. Therefore, it is possible to reschedule the scanning sequence of the sensing beams that need to be transmitted in mode 3.

[0085] For example, as shown in the lower part of Figure 10, the transmitting end may skip one or more sensing beams corresponding to the sensing signal transmitted in mode 3 during each round of scanning, and after one downlink transmission used for the communication signal is completed (or immediately before the next uplink communication), transmit the sensing signal in a third mode using the skipped one or more sensing beams. In actual implementations, one transmission of a downlink communication signal may correspond to scanning multiple rounds of sensing areas. In this case, the transmitting end may, as actually required, perform sensing using the skipped one or more sensing beams before the next uplink communication, according to the total sensing time length corresponding to the skipped sensing beams. Alternatively, the transmitting end may perform one sensing in each direction corresponding to the skipped one or more sensing beams before the next uplink communication.

[0086] Furthermore, there are cases where the communication signal has a high priority, and the sensing beam at an intermediate position in the scanning sequence strongly interferes with the communication signal. In this case, in addition to the processing method of transmitting only the communication signal and temporarily suspending sensing using the second mode, as shown in Figure 10, the transmitting end may use the first mode to maintain the transmission of both the communication signal and the sensing signal using the same time-frequency resources, but will not transmit the sensing signal using a sensing beam that corresponds to the strong interference. In other words, the transmitting end may continue sensing, but will not perform sensing in a direction that strongly interferes with communication.

[0087] According to this disclosure, when transmitting communication signals and sensing signals using the same time-frequency resources by employing the first mode, several measures need to be taken so that the receiving end can demodulate the communication signals and / or sensing signals from the received signals. In its basic form, a retransmission mechanism may be employed to ensure that the receiving end correctly receives the communication signals and / or sensing signals. However, such a retransmission mechanism can introduce delays that affect the reachable communication rate and lead to power waste. Therefore, this disclosure proposes preferred interference rejection and signal design methods.

[0088] In a preferred embodiment, the receiving end can demodulate a communication signal and / or sensing signal from the received signal transmitted in a first mode by performing an interference rejection operation. For example, the receiving end may determine the communication signal with the least noise in the received signal as the estimated communication signal. For example, the receiving end may jointly estimate the communication signal and sensing beam gain from the received signal based on at least an estimated communication beam gain and a sensing signal sequence. The receiving end may additionally jointly estimate the communication signal and sensing beam gain from the received signal based on at least one parameter. The at least one parameter may be, for example, at least one of the following parameters: signal-to-interference ratio level, sensing beam signal format, initial sensing beam gain value used for joint estimation, and number of beams in the sensing signal. For example, one or more of the at least one parameter may be indicated by the control information relating to the transmission of the communication signal and sensing signal, or may be predetermined or determined by the receiving end.

[0089] The following describes an example of an interference removal method according to this disclosure.

[0090] Let k be the length of the signal sequence transmitted by the transmitting end, and s be the length of the transmitted communication signal. c =[s1 c s2 c ,…,s k c] and the transmitted sensing signal is s s =[s1 s s2 s ,…,s k s ] and the signal received by the receiving end is y=[y1,y2,…,y k ] and the noise vector is n=[n1,n2,…,n k Assuming this is the case, the signal y received by the receiving end is y = q c s c +q s s s It can also be written as +n.

[0091] Here, the second term q s s s This is the sensing interference term.

[0092] In the above equation, the sensing signal sequence s s Generally, this is a fixed sequence known at the receiving end (e.g., a fixed sequence that has been notified or predetermined at the transmitting end).

[0099] The interference rejection method according to this disclosure allows the receiving end to favorably improve the signal-to-interference ratio gain of the communication signal and the sensing signal. Figure 11A shows a performance simulation diagram of the interference rejection method according to this disclosure. In the simulation in Figure 11A, the communication signal is assumed to be 64QAM modulated, the signal sequence length is 32, and the signal-to-noise ratio is 20 dB. As shown in Figure 11A, by applying the interference method according to this disclosure at interference levels (indicated as Signal to Interference Ratio (SIR) in the figure) from different sensing signals to the communication signal, as shown on the horizontal axis, the bit error ratio (BER) of the communication signal can be reduced, and a signal-to-interference ratio gain of approximately 2.5 dB can be provided.

[0100] In the exemplary interference rejection method described above, the receiving end demodulates the communication signal from the received signal based on the communication beam gain, which is an interference rejection parameter. Additionally, the receiving end further determines the signal-to-interference ratio level (for example, the receiving end determines the signal-to-interference ratio level based on the signal-to-interference ratio level).

number

[0101] In one preferred embodiment, the transmitting end can jointly design the sensing signal and the communication signal so that the receiving end can directly demodulate the communication signal and / or sensing signal from the received signal.

[0102] For example, the transmitting end may design the sensing signal as a signal orthogonal to the communication signal. For example, the transmitting end may design the sensing signal orthogonal to the communication signal using any appropriate method.

[0103] Furthermore, for example, by designing the sensing signal in association with the communication signal, the signal power gain of the communication signal received by the receiving end can be improved by adjusting the sensing signal. Equation 11 shows the sensing signal s of one exemplary embodiment according to the present disclosure. s This is the design method.

[0109] According to this disclosure, interference rejection performed by the receiving end may be used in combination with sensing signal design performed by the transmitting end. For example, the receiving end may design a sensing signal based on a communication signal, and at the same time, if the receiving end is still unable to demodulate the communication signal directly from the designed signal, it may perform interference rejection on the received signal to demodulate the communication signal.

[0110] According to this disclosure, for a sensing beam determined to be weakly interfering, the receiving end may preferably perform interference rejection operations to demodulate the communication signal, and for a sensing beam determined to be strongly interfering, the transmitting end may preferably design the sensing signal so that the receiving end can demodulate the communication signal. However, this disclosure is not limited thereto, and for example, the sensing signal design may be applied to a weakly interfering sensing beam, and for a strongly interfering sensing beam, the receiving end may attempt demodulation by interference rejection operations if no sensing signal is designed. When transmitting a sensing signal and a communication signal using the first mode, how the receiving end specifically receives and demodulates the signal may be predetermined / default, instructed by the transmitting side, or determined by the receiving side itself.

[0111] Figure 11B shows an exemplary performance simulation diagram of the interference management scheme according to the present disclosure. In this scheme, an interference rejection method is applied to the weakly interfering sensing beam, and a joint signal design method is applied to the strongly interfering sensing beam. In the simulation in Figure 11B, the communication signal is 64QAM modulated, the signal sequence length is 32, the signal-to-interference ratio for the weakly interfering sensing beam is 15 dB, and the signal-to-interference ratio for the strongly interfering sensing beam is 5 dB. If the interference management scheme according to the present disclosure is not applied, when the communication signal cannot be successfully demodulated, the system must use a retransmission mechanism to ensure that the receiving end successfully receives the communication data, and retransmission may reduce the reachable rate. As shown in Figure 11B, compared to not applying the interference management scheme according to the present disclosure, the interference management scheme of the preferred embodiment according to the present disclosure can significantly improve the reachable rate of the communication sensing integrated system (by about 10% to 15%, as shown in the figure), thereby significantly improving the performance of the communication sensing integrated system.

[0112] Details of the implementation of the sensing communication integrated system described in this disclosure have been explained. Below, with reference to Figure 12, an example of information exchange 120 between the transmitting and receiving ends of the communication sensing integrated system described in this disclosure will be explained.

[0113] As shown in Figure 12, in S1202, the transmitting end may first determine the arrangement for transmitting the communication signal and the sensing signal. For example, the transmitting end may determine the sensing beam arrangement, the initially determined interference intensity corresponding to the multiple sensing beams to be scanned corresponding to the sensing area, the transmission mode of the communication signal and the sensing signal, the duration of the transmission mode, etc. Then, in S1204, the transmitting end may instruct the receiving end on control information regarding the transmission of the communication signal and the sensing signal. For example, the control information may be information indicating the sensing beam arrangement. For example, the control information may be at least one of the arrangements for transmitting the communication signal and the sensing signal determined by the transmitting end. For example, the transmitting end may explicitly transmit at least a part of the control information to the receiving end. At least a part of the control information may be implicitly indicated based on, for example, an agreement between the transmitting end and the receiving end, or provisions in relevant standards. In S1206, the transmitting end may transmit the communication signal and / or sensing signal based, for example, the arrangement for transmitting the communication signal and the sensing signal determined in S1202.

[0114] Next, in S1208, the receiving end may receive and / or process the signal. For example, the receiving end may decide how to receive and / or process the signal, at least according to the control information instructed by the transmitting end. For example, if the transmission mode is the second mode, the receiving end may receive the communication signal directly. For example, if the transmission mode is the third mode, and the receiving end actively participates in sensing, it may determine whether the sensing signal is directed at itself, and if yes, it may receive the sensing signal directly. Note that if the transmission mode is the third mode, and the receiving end does not actively perform sensing, or if the sensing signal is not directed at itself, the receiving end does not have to receive the sensing signal. For example, if the transmission mode is the first mode, the receiving end may demodulate the communication signal and / or sensing signal by processing the received information, for example, according to a default processing method or according to a method instructed by the transmitting end. For example, such a processing method may involve direct demodulation (e.g., if the transmitting end has designed the sensing signal based on the communication signal), or interference rejection, or direct demodulation first and then interference rejection if demodulation is unsuccessful, or interference rejection for beams labeled as weakly interfering and direct demodulation for beams labeled as strongly interfering (e.g., the transmitting end may design only the strongly interfering sensing beam based on the communication signal), or any other appropriate method (e.g., requesting retransmission if the communication signal and / or sensing signal cannot be demodulated correctly). Furthermore, if the receiving end participates in sensing, the receiving end may process the received sensing signal to obtain sensing information and, if necessary, report the obtained sensing information to the control equipment of the wireless network (or further report it to the network element responsible for sensing in the core network via the control equipment) for further processing.

[0115] While receiving / processing the signal, or periodically thereafter, the receiving end may measure interference from the sensing signal to the communication signal (e.g., in S1212). For example, this measurement may be performed, for example, during interference rejection (e.g., by estimating the sensing beam gain), or by requesting a reference signal (e.g., in S1210). Depending on the measurement result, the receiving end may feed back the interference intensity of the sensing beam to the transmitting end in S1214. For example, the receiving end may directly feed back a specific numerical value of the interference intensity, or the receiving end may compare the interference intensity with a predetermined threshold and then feed back to the transmitting end an indication of whether the sensing beam is a weakly interfering beam or a strongly interfering beam.

[0116] In S1216, the transmitting end may adjust the arrangement of transmissions for communication signals and sensing signals. For example, such adjustments may be based on changes in the priority of communication services and sensing services, or changes in the interference intensity of the sensing beam fed back by the receiving end.

[0117] Figure 12 shows an exemplary information exchange flow. The order of operations in this flow is not necessarily fixed; for example, the operation in S1210 may be performed periodically, semi-periodicly, or semi-continuously. The operations in S1212 and S1214 may be performed approximately synchronously with S1208. Not all operations in this flow are necessarily required; for example, in some cases, an implicitly indicated method may be used instead of the operation in S1204, and the operations in S1210, S1212, S1214, and S1216 may all be selective operations. This flow may also involve other operations; for example, the receiving end may additionally transmit sensing results to the transmitting end.

[0118] The above has been a detailed description of the present disclosure with reference to the drawings. The solutions of the present disclosure advantageously provide a communication sensing integrated system that can effectively combine communication and sensing. According to the present disclosure, the communication module can share hardware, waveform signals, etc., with the sensing module, thereby saving hardware resources and spectral overhead and improving system performance. The present disclosure provides multiple selective modes for transmitting communication signals and sensing signals, allowing the most appropriate transmission mode to be selected according to actual demands. According to the present disclosure, even when transmitting communication signals and sensing signals using the same time-frequency resources, interference from the sensing signal to the communication signal can be effectively reduced, eliminated, or avoided, thereby enabling the receiving end to perform correct demodulation. By applying the method of overcoming interference from the sensing signal to the communication signal according to the present disclosure, the number of retransmissions can be reduced, thereby increasing the reachable rate of communication and reducing power waste.

[0122] The CPU 1301, ROM 1302, and RAM 1303 are connected to each other via bus 1304. The input / output interface 1305 is also connected to bus 1304.

[0123] The input unit 1306, which includes a keyboard and mouse, the output unit 1307, which includes a display such as a cathode ray tube (CRT) or liquid crystal display (LCD) and speakers, the storage unit 1308, which includes a hard disk, and the communication unit 1309, which includes a network interface card such as a LAN card or modem, are connected to the input / output interface 1305. The communication unit 1309 performs communication processing via a network, such as the Internet.

[0124] If necessary, drive 1310 is also connected to input / output interface 1305. Removable media 1311, such as magnetic disks, optical disks, magneto-optical disks, or semiconductor memory, are installed on drive 1310 as necessary, and computer programs read from them are installed on storage 1308 as necessary.

[0125] When the above series of processes are implemented using software, the programs that make up the software are installed from a network, such as the internet, or from a storage medium, such as removable media 1311.

[0126] Those skilled in the art should understand that such a storage medium is not limited to the removable media 1311 shown in Figure 13, which stores the program and is distributed separately from the device to provide the program to the user. Examples of removable media 1311 include magnetic disks (including floppy disks®), optical disks (including optical disk read-only memory (CD-ROM) and digital versatile disks (DVD)), magneto-optical disks (including MiniDisc (MD)®), and semiconductor memory. Alternatively, the storage medium may be a ROM 1302, a hard disk included in storage 1308, etc., which stores the program and is distributed to the user together with the device containing them.

[0127] The technology disclosed herein can be applied to a variety of products.

[0128] For example, the electronic devices 10 and 20 according to the embodiments of this disclosure can be implemented as various control devices / base stations, or may be included in various control devices / base stations. For example, the electronic devices 10 and 20 according to the embodiments of this disclosure can be implemented as various terminal devices / user devices, or may be included in various terminal devices / user devices.

[0129] For example, the control equipment / base station referred to in this disclosure may be implemented as any type of base station, evolving node B (gNB) such as macro gNBs and small gNBs. Small gNBs may be gNBs that cover cells smaller than macrocells, such as pico gNBs, micro gNBs and femto gNBs. Alternatively, the base station may be implemented as any other type of base station, such as node Bs and base transceiver stations (BTSs). The base station may include an entity (also called base station equipment) configured to control the radio communication and one or more remote radio heads (RRHs) located separately from the entity. Furthermore, various types of terminals described later can operate as base stations by performing base station functions temporarily or semi-permanently.

[0130] For example, the terminal equipment referred to in this disclosure may, in some examples, also be called user equipment and may be implemented as a mobile terminal (e.g., a smartphone, tablet personal computer (PC), notebook PC, portable game console, portable / dongle mobile router, and digital imaging device) or an in-vehicle terminal (e.g., a car navigation system). User equipment may be implemented as a terminal that performs machine-to-machine (M2M) communication (also called a machine-type communication (MTC) terminal). User equipment may also be a wireless communication module (e.g., an integrated circuit module including a single chip) mounted on each of the above terminals.

[0131] Examples of this disclosure will be described below with reference to Figures 14 to 17.

[0132] [Examples related to base stations] It should be understood that the term "base station" in this disclosure has the full scope of its ordinary meaning and includes radio communication stations that are at least part of a radio communication system or radio system in order to perform communications. Examples of base stations include, for example, one or both of a base station transceiver (BTS) and / or a base station controller (BSC) in a GSM® system, one or both of a radio network controller (RNC) and / or a Node B in a WCDMA® system, an eNB in ​​LTE and LTE-Advanced systems, a gNB, eLTE eNB, etc. appearing in a 5G communication system, or a corresponding network node in a future communication system, but are not limited to these. Some functions of base stations in this disclosure may be implemented as entities with control functions over communications in D2D, M2M and V2V communication scenarios, or as entities with spectrum tuning functions in cognitive radio communication scenarios.

[0133] (Example 1) Figure 14 is a block diagram showing a first example of an exemplary configuration of a gNB to which the technology of the present disclosure can be applied. The gNB 1400 includes a plurality of antennas 1410 and base station equipment 1420. The base station equipment 1420 and each antenna 1410 can be connected to each other via RF cables. In one embodiment, the gNB 1400 (or base station equipment 1420) herein may correspond to the electronic equipment 10 and / or electronic equipment 80 described above.

[0134] Each of the antennas 1410 includes one or more antenna elements (for example, multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used by the base station equipment 1420 to transmit and receive radio signals. As shown in Figure 14, the gNB 1400 may include multiple antennas 1410. For example, multiple antennas 1410 may be compatible with multiple frequency bands used by the gNB 1400.

[0135] The base station equipment 1420 includes a controller 1421, memory 1422, network interface 1423, and wireless communication interface 1425.

[0136] The controller 1421 may be, for example, a CPU or a DSP, and operates various functions of the upper layers of the base station equipment 1420. For example, the controller 1421 generates data packets based on data in signals processed by the wireless communication interface 1425 and transmits the generated packets via the network interface 1423. The controller 1421 can bundle data from multiple baseband processors to generate bundle packets and transmit the generated bundle packets. The controller 1421 may have logic functions that perform the following controls, such as radio resource control, radio bearer control, mobility management, reception control, and scheduling. This control can be performed in conjunction with nearby gNBs or core network nodes. The memory 1422 includes RAM and ROM and stores programs executed by the controller 421 and various types of control data (e.g., terminal lists, transmission power data, and scheduling data).

[0137] Network interface 1423 is a communication interface for connecting base station equipment 1420 to the core network 1424. Controller 1421 can communicate with core network nodes or other gNBs via network interface 1423. In this case, gNB 1400 and the core network nodes or other gNBs can be connected to each other by logic interfaces (e.g., S1 interface and X2 interface). Network interface 1423 may be a wired communication interface or a wireless communication interface used for a wireless backhaul line. If network interface 1423 is a wireless communication interface, network interface 1923 can be used for wireless communication using a higher frequency band than the frequency band used by wireless communication interface 1425.

[0138] The wireless communication interface 1425 supports any cellular communication scheme (e.g., Long Term Evolution (LTE) and LTE-Advanced) and provides wireless connectivity to terminals in cells located on the gNB 1400 via the antenna 1410. The wireless communication interface 1425 may typically include, for example, a baseband (BB) processor 1426 and RF circuitry 1427. The BB processor 1426 can perform, for example, encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, as well as various types of signal processing at different layers (e.g., L1, Media Access Control (MAC), Radio Link Control (RLC), Packet Data Aggregation Protocol (PDCP)). Instead of the controller 1421, the BB processor 1426 may have some or all of the above logic functions. The BB processor 1426 may be a memory in which a communication control program is stored, or it may be a module including a processor and associated circuitry configured to execute the program. Program updates can change the functionality of the BB processor 1426. This module may be a card or bread inserted into a slot in base station equipment 1420. Alternatively, this module may be a chip mounted on a card or bread. Simultaneously, the RF circuit 1427 may include, for example, a mixer, filter, and amplifier, and be capable of transmitting and receiving radio signals via the antenna 1410. Figure 14 shows an example in which one RF circuit 1427 is connected to one antenna 1410, but the disclosure is not limited to this illustration, and one RF circuit 1427 may be connected to multiple antennas 1410 simultaneously.

[0139] As shown in Figure 14, the wireless communication interface 1425 may include multiple BB processors 1426. For example, multiple BB processors 1426 may be compatible with multiple frequency bands used by the gNB1400. As shown in Figure 14, the wireless communication interface 1425 may include multiple RF circuits 1427. For example, multiple RF circuits 1427 may be compatible with multiple antenna elements. Although Figure 14 shows an example in which the wireless communication interface 1425 includes multiple BB processors 1426 and multiple RF circuits 1427, the wireless communication interface 1425 may include a single BB processor 1426 or a single RF circuit 1427.

As shown in Figure 15, the gNB1530 may include multiple antennas 1540. For example, multiple antennas 1540 may be compatible with multiple frequency bands used by the gNB1530.

[0142] The base station equipment 1550 includes a controller 1551, a memory 1552, a network interface 1553, a wireless communication interface 1555, and a connection interface 1557. The controller 1551, memory 1552, and network interface 1553 are similar to the controller 1421, memory 1422, and network interface 1423 described with reference to Figure 14.

[0143] The wireless communication interface 1555 supports any cellular communication scheme (e.g., LTE and LTE-Advanced) and provides wireless communication to a terminal located in the sector corresponding to the RRH1560 via the RRH1560 and antenna 1540. The wireless communication interface 1555 may typically include, for example, a BB processor 1556. The BB processor 1556 is similar to the BB processor 1426 described with reference to Figure 14, except that the BB processor 1556 is connected to the RF circuit 1564 of the RRH1560 via connection interface 1557. As shown in Figure 15, the wireless communication interface 1555 may include multiple BB processors 1556. For example, multiple BB processors 1556 may be compatible with multiple frequency bands used by the gNB1530. Although Figure 15 shows an example in which the wireless communication interface 1555 includes multiple BB processors 1556, the wireless communication interface 1555 may include a single BB processor 1556.

[0144] The connection interface 1557 is an interface for connecting the base station equipment 1550 (wireless communication interface 1555) to the RRH1560. The connection interface 1557 may also be a communication module for communication in the high-speed line described above that connects the base station equipment 1550 (wireless communication interface 1555) to the RRH1560.

[0146] The connection interface 1561 is an interface for connecting the RRH1560 (wireless communication interface 1563) to the base station equipment 1550. The connection interface 1561 may also be a communication module for communication on the high-speed line described above.

[0147] The wireless communication interface 1563 transmits and receives radio signals via the antenna 1540. The wireless communication interface 1563 may typically include, for example, an RF circuit 1564. The RF circuit 1564 may include, for example, a mixer, a filter, and an amplifier, and may transmit and receive radio signals via the antenna 1540. Figure 15 shows an example in which one RF circuit 1564 is connected to one antenna 1540, but the disclosure is not limited to this illustration, and one RF circuit 1564 may be connected to multiple antennas 1540 simultaneously.

[0148] As shown in Figure 15, the wireless communication interface 1563 may include multiple RF circuits 1564. For example, multiple RF circuits 1564 can support multiple antenna elements. Although Figure 15 shows an example in which the wireless communication interface 1563 includes multiple RF circuits 1564, the wireless communication interface 1563 may also include a single RF circuit 1564.
