Description

A communication device, system and method

[0001] This application claims priority to Chinese Patent Application No. 202411839612.X, filed on December 12, 2024, entitled "A Communication Device, System and Method", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more specifically, to a communication apparatus, system, and method. Background Technology

[0003] The evolution of communication technologies and the proliferation of smart devices have led to an increasing demand for uplink speeds. However, due to limitations in hardware performance, device power consumption, and deployment space, the uplink transmission performance of terminal devices is restricted, especially in scenarios such as cell edges, weak coverage, or congestion, where uplink transmission may not meet the target requirements.

[0004] Therefore, how to improve uplink transmission performance is an urgent problem to be solved. Summary of the Invention

[0005] This application provides a communication device that improves uplink transmission performance by integrating a communication module into a peripheral device.

[0006] In a first aspect, a communication device is provided, comprising: a peripheral device, the peripheral device being a product used in conjunction with a first device; and a communication module connected to the peripheral device, through which the first device communicates with a second device; the communication module comprising: an antenna array, the antenna array satisfying a first condition; the first condition including at least one of the following: the antenna gain of the antenna array is higher than the antenna gain of the first device; the antenna coverage area of ​​the antenna array is greater than the antenna coverage area of ​​the first device; and the antenna radiation efficiency of the antenna array is higher than the antenna radiation efficiency of the first device.

[0007] For example, peripheral devices may include fill lights, brackets, or protective cases, etc. This application embodiment does not limit the type or function of peripheral devices.

[0008] Based on the above solution, integrating the communication module into the peripheral device allows for a more compact structure; the superior antenna performance compared to the first device (e.g., the terminal device) enhances the wireless signal of the first device, thereby improving its uplink transmission performance. Simultaneously, the peripheral device retains its original functionality.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the antenna array includes at least one bidirectional antenna; the at least one bidirectional antenna includes a first directional antenna and a second directional antenna; wherein a first end of the first directional antenna is connected to a first end of the second directional antenna via a power divider.

[0010] Based on the above scheme, the bidirectional antenna ensures coverage in two side firing directions through two directional antennas with opposite directions. Compared with the single omnidirectional antenna in the current technology, the antenna gain of this bidirectional antenna is improved by about 2 to 3 dB.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the first directional antenna and the second directional antenna share a reflector.

[0012] Based on the above scheme, the first directional antenna and the second directional antenna have a more compact structure, which facilitates conformal design with the surrounding structure.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the antenna array further includes at least one third directional antenna; each of the at least one third directional antenna is perpendicular to each of the at least one bidirectional antenna.

[0014] Based on the above scheme, directional antennas can be used to fill in coverage blind spots after bidirectional antenna arrays are assembled, thereby improving coverage performance.

[0015] In conjunction with the first aspect, in some implementations of the first aspect, each of the at least one bidirectional antenna is arranged in a ring array.

[0016] Based on the above scheme, the bidirectional antenna array has a beamforming effect, the beam gain is increased, and the antenna gain is further improved compared to the case of a single bidirectional antenna.

[0017] In conjunction with the first aspect, in some implementations of the first aspect, the first directional antenna, the second directional antenna, and / or the third directional antenna are E-shaped patch antennas; or, the first directional antenna, the second directional antenna, and / or the third directional antenna are grid antennas.

[0018] Based on the above solutions, the slotted or hollowed-out design of the antenna can improve the antenna bandwidth and reduce the impact of the antenna on the original functions of peripheral devices, so that the antenna structure can be conformally designed with peripheral devices.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the peripheral device is a fill light; the reflector is located on the dielectric substrate on which the fill light strip is located; the at least one bidirectional antenna is arranged in a ring array, including: the at least one bidirectional antenna is arranged in a ring array along the light strip.

[0020] Based on the above scheme, the antenna array structure is shared with the supplementary lighting structure, which can improve the antenna gain while reducing the impact of the light strip circuit on the antenna. When the first directional antenna, the second directional antenna, and / or the third directional antenna are grid antennas, the impact of the antenna structure on the light transmittance of the supplementary lighting can also be reduced.

[0021] Secondly, a communication method is provided, which can be executed by a first device. Unless otherwise specified, the "first device" in this application can refer to a first device (e.g., a terminal device), a component of the first device, or a logic module or software that can implement all or part of the functions of the first device. For ease of description, the following description uses execution by a first device as an example.

[0022] The method includes: receiving first configuration information from a second device, the first configuration information including first beam information and first location information; sending first information to the second device, the first information being determined based on the first location information, for indicating whether the location of the first device has changed; when the first information indicates that the location of the first device has not changed, the first device communicates with the second device based on the first beam information;

[0023] The second device includes: an antenna array, the antenna array satisfying a first condition; the first condition includes at least one of the following: the antenna gain of the antenna array is higher than the antenna gain of the first device; the antenna coverage area of ​​the antenna array is greater than the antenna coverage area of ​​the first device; the antenna radiation efficiency of the antenna array is higher than the antenna radiation efficiency of the first device.

[0024] In one possible implementation, the second device is the communication device described in the first aspect above and any of its possible implementations.

[0025] Based on the above scheme, since the positions of the first device and the second device are relatively fixed, the channel environment changes relatively slowly. By carrying the first location information in the first configuration information, the first device can determine whether its own position has changed based on the first location information. If it has not changed, the first device and the second device can communicate based on the first beam information corresponding to the first location information without having to perform beam measurement, thereby reducing system overhead.

[0026] In conjunction with the second aspect, in some implementations of the second aspect, before receiving the first configuration information, the method further includes: sending a first request message to the second device, the first request message being used to request the establishment of a connection with the second device; receiving a first sensing signal from the second device, the first sensing signal being used to detect the location of the first device; and sending a first reference signal to the second device, the first reference signal being used to perform channel measurement between the first device and the second device.

[0027] In conjunction with the second aspect, in certain implementations of the second aspect, the first information is determined based on the first location information, including:

[0028] The first information is determined based on the first location information and the second location information, and the second location information is determined based on the inertial navigation system of the first device. When the first location information is the same as the second location information, or the absolute value of the coordinate difference between the first location information and the second location information is less than a first value, the first information indicates that the position of the first device has not changed. When the first location information is different from the second location information, or the absolute value of the coordinate difference between the first location information and the second location information is greater than the first value, the first information indicates that the position of the first device has changed.

[0029] Thirdly, a communication method is provided, which can be executed by a second device. Unless otherwise specified, the "second device" in this application can refer to a second device, a component within a second device, or a logic module or software capable of implementing all or part of the functions of the second device.

[0032] In one possible implementation, the second device is the communication device described in the first aspect above and any of its possible implementations.

[0033] In conjunction with the third aspect, in some implementations of the third aspect, before sending the first configuration information, the method further includes:

[0034] The system receives a first request message from the first device, which is used by the first device to request the establishment of a connection with the second device; sends a first sensing signal to the first device, which is used to detect the location of the first device; and receives a first reference signal from the first device, which is used to perform channel measurement between the first device and the second device.

[0035] In conjunction with the third aspect, in some implementations of the third aspect, the first information is determined based on the first position information, including: the first information is determined based on the first position information and the second position information, and the second position information is determined based on the inertial navigation system of the first device; when the first position information and the second position information are the same, or the absolute value of the coordinate difference between the first position information and the second position information is less than a first value, the first information indicates that the position of the first device has not changed; when the first position information and the second position information are different, or the absolute value of the coordinate difference between the first position information and the second position information is greater than the first value, the first information indicates that the position of the first device has changed.

[0036] It should be noted that the technical effects corresponding to the third aspect can be referred to the technical effects of the second aspect mentioned above, and will not be elaborated here.

[0065] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0066] The technical solutions provided in this application can be applied to various communication systems, such as: 5th generation (5G) systems (or New Radio (NR) systems), beyond 5G (B5G) mobile communication systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, and LTE time division duplex (TDD) systems. The technical solutions provided in this application can also be applied to future communication networks. Furthermore, the technical solutions provided in this application can be applied to device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), and Internet of Things (IoT) communication systems or other communication systems.

[0067] In addition, the technical solution provided in this application also supports short-range communication.

[0068] Short-range communication enables communication between electronic devices located close to each other. Current mainstream short-range communication access technologies include Wi-Fi, Bluetooth, and ZigBee. With the development of the Internet of Things (IoT), new application scenarios such as smart cars, smart homes, smart terminals, and smart manufacturing have emerged, giving rise to next-generation short-range access technologies (e.g., Sparklink Alliance access technologies). Taking Sparklink Alliance access technologies as an example, they include, but are not limited to, Sparklink Basic (SLB) access technology and Sparklink Low Energy (SLE) access technology. SLB access technology can support high-bandwidth services such as screen projection, virtual reality (VR), and vehicular communication, while SLE access technology can support low-bandwidth, low-data-rate, and low-power services such as audio playback, keyboard, mouse, and electronic pen communication. For ease of description, in the following embodiments, SLB access technology will be referred to as SLB, and SLE access technology as SLE.

[0069] To facilitate understanding of the embodiments of this application, the terms involved in this application will be briefly explained first.

[0070] It should be understood that the basic concepts of the terms introduced below are functional descriptions, and the specific names of the terms are not limited in the embodiments of this application.

[0071] 1. Coupling

[0072] Coupling can be understood as direct coupling and / or indirect coupling, and "coupled connection" can be understood as direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection," which can be understood as components physically contacting and conducting electricity; it can also be understood as the form of connection between different components in the circuit structure through physical lines that can transmit signals, such as copper foil or wires on a printed circuit board (PCB); "indirect coupling" can be understood as two conductors conducting electricity in a way that is airtight or without contact.

[0073] Alternatively, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gaps between two conductive parts.

[0074] 2. Antenna

[0075] An antenna may include one or more of the following: radiating elements (the number of radiating elements is not limited), a reflector (or base plate, antenna panel), a feed network (or power distribution network), a phase shifter, and an antenna radome.

[0076] Its constituent parts are described in detail below:

[0077] (1) Radiation unit

[0078] A radiating element is a device in an antenna used to receive / transmit electromagnetic wave radiation. It can include antenna elements (simply called dipoles, which guide and amplify electromagnetic waves). In some cases, the term "antenna" is narrowly defined as the radiating element, which converts guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiating element via a feed line. The radiating element converts this energy into electromagnetic wave energy of a specific polarization and radiates it in the desired direction. The receiving radiating element converts electromagnetic wave energy of a specific polarization from a specific direction in space back into modulated high-frequency current energy, which is then transmitted to the receiver input via a feed line.

[0079] The radiating unit may include a conductor with a specific shape and size, such as a wire or a sheet, and this application does not limit the specific shape.

[0080] (2) Reflector

[0081] A reflector can also be called a floor, base plate, antenna panel, or metal reflector. Reflectors are generally made of metal and have an electrical effect on the antenna. For example, reflectors can improve the antenna's signal reception sensitivity by reflecting and focusing the signal onto the receiving point, thereby enhancing the antenna's receiving and transmitting capabilities. They also block and shield interference from electromagnetic waves originating from the back of the reflector (in the opposite direction to the antenna's radiation direction), enhancing the antenna's directivity. Reflectors can also serve as the main structure of the antenna, supporting the radiating element array and the feed network.

[0082] (3) Power supply network

[0083] Feeding, or power supply, is the function of a feed network. In the antenna field, feeding can refer to supplying power or energy to the antenna. The role of the feed network is to feed signals to the various radiating elements of the antenna with a certain amplitude and phase, or to feed signals received from the various radiating elements to the signal processing unit of the base station with a certain amplitude and phase. Feed networks are typically composed of controlled impedance transmission lines.

[0084] The functionality of a feed network can be implemented based on feed circuits. These feed circuits are used for receiving and / or transmitting radio frequency (RF) signals. Feed circuits can include transceivers and RF front-end circuitry. In some cases, the term "feed circuit" is narrowly interpreted as an RF chip (RFIC), which can be considered to include both the RF front-end circuitry (or RF front-end chip) and the transceiver. Feed circuits have the function of converting radio waves (e.g., RF signals) into signals (e.g., digital signals). Generally, it is considered part of the RF component.

[0085] In some possible implementations, the electronic device may also include a test socket (or RF socket or RF test socket). This test socket can be used to insert a coaxial cable to test the characteristics of the RF front-end circuitry or the radiator of the antenna. The RF front-end circuitry can be considered as the circuitry coupled between the test socket and the transceiver.

[0086] In some possible implementations, the RF front-end circuitry can be integrated into an RF front-end chip in the electronic device, or the RF front-end circuitry and transceiver can be integrated into an RF chip in the electronic device.

[0087] It should be noted that the power supply network may also include a grounding structure / power supply structure. The grounding structure / power supply structure may include connectors (e.g., metal posts (probes)). The radiating elements are coupled to the ground via the grounding structure, or the radiating elements are coupled to the power supply circuit via the power supply structure.

[0088] It should be noted that grounding refers to coupling with the aforementioned ground / floor in any way. For example, grounding can be achieved through physical grounding, such as through a structural component of the mid-frame to achieve a physical ground at a specific location on the frame (or, physical ground). For example, grounding can be achieved through device grounding, such as through devices like capacitors / inductors / resistors connected in series or parallel (or, device ground).

[0089] In some possible implementations, the power supply structure may include a power supply point and / or a microstrip line electrically connected to the power supply point, and the grounding structure may include a grounding point.

[0090] In some possible implementations, the power supply network may also include a phase shifter; and / or, the power supply network may also include devices such as combiners and filters.

[0091] It should be noted that any of the above-mentioned grounding layers, grounding plates, or grounding metal layers are made of conductive materials. In one embodiment, the conductive material may be any of the following: copper, aluminum, stainless steel, brass and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil on an insulating substrate and tin-plated copper, cloth impregnated with graphite powder, graphite-coated substrate, copper-plated substrate, brass-plated substrate, and aluminum-plated substrate. Those skilled in the art will understand that the grounding layer / grounding plate / grounding metal layer may also be made of other conductive materials.

[0092] It should be noted that the "end / point" in the embodiments of this application, such as the "end / point" in the first end / second end / feed end / ground end / feed point / ground point / connection point of the antenna radiating element, should not be narrowly interpreted as necessarily being an endpoint or end physically disconnected from other radiating elements. It can also be considered as a point or segment on a continuous radiating element. In one embodiment, "end / point" may include a connection / coupling region on the antenna radiating element or microstrip line that couples to other conductive structures. For example, the feed end / feed point may be a connection / coupling region on the antenna radiating element that couples to a feed structure or feed circuit (e.g., a region facing a part of the feed circuit). Similarly, the ground end / ground point may be a connection / coupling region on the antenna radiating element that couples to a ground structure or ground circuit (e.g., a region facing a part of the ground circuit).

[0093] 3. Antenna Array

[0094] An antenna array is an array structure consisting of at least one antenna arranged according to a certain geometric pattern. At least one antenna can share the same feed network to operate.

[0095] 4. Antenna pattern

[0096] Antenna radiation pattern, also known as radiation pattern, is a graphical representation of the relative field strength (normalized modulus) of the antenna's radiated field at a certain distance from the antenna (far field) as a function of direction. Two-dimensional radiation patterns are typically represented by two mutually perpendicular planar radiation patterns passing through the antenna's maximum radiation direction.

[0097] 5. Antenna Gain

[0098] Antenna gain characterizes the degree to which an antenna concentrates the radiated input power. Generally, the narrower the main lobe and the smaller the side lobes of the antenna pattern, the higher the antenna gain.

[0099] 6. Antenna system efficiency (total efficiency)

[0100] Antenna system efficiency, also known as overall efficiency, refers to the ratio of the power radiated into space by the antenna (i.e. the power that effectively converts the electromagnetic wave portion) to the power input at the antenna port.

[0101] 7. Antenna radiation efficiency

[0102] Antenna radiation efficiency refers to the ratio of the power radiated by the antenna into space (i.e., the power effectively converted into electromagnetic waves) to the active power input to the antenna. The active power input to the antenna equals the antenna's input power minus reflected power minus power coupled to other ports. Loss power mainly includes return loss power and ohmic loss power of metals and / or dielectric loss power. Radiation efficiency is a measure of an antenna's radiation capability; metal loss and dielectric loss are both factors affecting radiation efficiency.

[0103] Those skilled in the art will understand that efficiency is generally expressed as a percentage, and there is a corresponding conversion relationship between it and dB. The closer the efficiency is to 0dB, the better the efficiency of the antenna.

[0104] Figure 1 is a schematic diagram of the architecture of a communication system 100 applicable to an embodiment of this application.

[0105] As shown in Figure 1, the communication system 100 may include network equipment 110, terminal equipment 120 and new terminal equipment 130.

[0106] The terminal device 120 in this embodiment can be a user-side device with wireless transceiver capabilities, such as a fixed device, mobile device, handheld device (e.g., mobile phone), wearable device, vehicle-mounted device, or a wireless device (e.g., communication module, modem, or chip system, etc.) built into the aforementioned devices. The terminal device is used to connect people, objects, and machines, and can be widely used in various scenarios, such as: cellular communication, device-to-device (D2D) communication, V2X communication, machine-to-machine / machine-type communications (M2M / MTC) communication, the Internet of Things, virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical care, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, drones, robots, and other scenarios. For example, a terminal device can be a handheld terminal in cellular communication, a communication device in D2D, an IoT device in MTC, a surveillance camera in intelligent transportation and smart cities, or a communication device on a drone, etc. Terminal devices are sometimes referred to as user equipment (UE), user terminal, user device, user unit, user station, terminal, access terminal, access station, UE station, remote station, mobile device, or wireless communication device, etc. In the embodiments of this application, the device used to implement the functions of the terminal device can be the terminal device itself, or it can be a device capable of supporting the terminal device in implementing that function, such as a chip system or a combination of devices or components capable of implementing the functions of the terminal device. This device can be installed in the terminal device.

[0107] The network device 110 in this embodiment can be any communication device with wireless transceiver capabilities used for communicating with terminal devices. The network device can be a device in a radio access network (RAN) that provides wireless communication capabilities to terminal devices, referred to as RAN equipment. For example, the network device can be a base station, an evolved NodeB (eNodeB), a next-generation NodeB (gNB) in a 5G mobile communication system, a 3GPP subsequent evolution base station, a transmission reception point (TRP), an access node in a WiFi system, a wireless relay node, a wireless backhaul node, etc. In communication systems employing different radio access technologies (RATs), the name of the device with base station functionality may differ. For example, in an LTE system, it can be called an eNB or eNodeB, and in a 5G or NR system, it can be called a gNB. This application does not limit the specific name of the base station. The network device can include one or more co-located or non-co-located transmission and reception points. For example, a network device may include one or more central units (CUs), one or more distributed units (DUs), or one or more CUs and one or more DUs. Exemplarily, the functionality of a CU can be implemented by a single entity or different entities. For instance, the functionality of a CU can be further divided, separating the control plane and user plane and implementing them through different entities, namely a control plane CU entity (i.e., CU-CP entity) and a user plane CU entity (i.e., CU-UP entity). The CU-CP and CU-UP entities can be coupled with DUs to jointly complete the functions of the access network device. In this way, some functions of a radio access network device can be implemented through multiple network function entities. These network function entities can be network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). As another example, in vehicle-to-everything (V2X) technology, the access network device can be a roadside unit (RSU). Multiple access network devices in a communication system can be base stations of the same type or different types. Base stations can communicate with terminal devices directly or through relay stations.

[0108] In this application embodiment, the device for implementing the network device function can be the network device itself, or a device capable of supporting the network device in implementing the function, such as a chip system or a combination device or component capable of implementing the access network device function. This device can be installed in the network device. In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. In this application embodiment, the chip system can be composed of chips or may include chips and other discrete devices.

[0109] It should be noted that, in order to accommodate the size and clearance requirements of terminal devices, current technologies typically employ PIFA, monopole, dipole, and loop antennas at the bezel of terminal device 120 to achieve wireless communication with network device 110. However, due to limitations in hardware performance, device power consumption, and deployment space, the antenna gain of terminal device 120 is generally low. Furthermore, the hand-held grip can negatively impact antenna matching, radiation pattern, and efficiency, thus limiting the uplink transmission performance of terminal device 120.

[0110] To address this issue, a novel terminal device 130 is also introduced into the communication system 100 to which this application embodiment applies.

[0111] It should be noted that the new terminal device 130 is a new device that integrates wireless signal forwarding function into the peripheral device. This allows wireless communication capability to be introduced while retaining the original function of the peripheral device. The terminal device 120 can enhance antenna performance through the new terminal device 130 to improve uplink transmission performance.

[0112] It should also be noted that the peripheral devices can be products used in conjunction with the terminal device 120. For example, the peripheral devices may include fill lights, brackets, or protective cases. This application embodiment does not limit the type or function of the peripheral devices.

[0113] Figure 2 is a structural schematic diagram of a novel terminal device 130 applicable to an embodiment of this application.

[0114] As shown in Figure 2, the new terminal device 130 includes a central processing module 210.

[0115] Optionally, the new terminal device 130 may also include a short-range module 220, a cellular module 230, and / or a wired connection module 240.

[0116] The central processing module 210 may include: a user-side transmission interface module, a service forwarding module, and a network-side transmission interface module.

[0117] The user-side transmission interface module is used to realize the connection between the new terminal device 130 and the terminal device 120.

[0118] For example, the novel terminal device 130 and terminal device 120 can be connected via wired or wireless means. The wired connection can be implemented using the wired connection module 240; for example, communication between the novel terminal device 130 and terminal device 120 can be achieved through a network port or a Type-C interface. The wireless connection can be implemented using the cellular module 230 or the short-range module 220; for example, communication between the novel terminal device 130 and terminal device 120 can be achieved through cellular communication (e.g., LTE or 5G); or through short-range communication (e.g., WiFi, Bluetooth, UWB, or satellite communication).

[0119] The network-side transmission interface module is used to enable the connection between the new terminal device 130 and cellular signals (e.g., LTE signals or 5G signals). Optionally, in order to reduce interference between signals transmitted on the same frequency, the network side and the user side can also use wireless signals of different frequencies for transmission.

[0120] The service forwarding module is used to forward service data between the user side and the network side, and to perform some necessary conversion operations.

[0121] It should be understood that the embodiments of this application do not limit the specific connection method used between the novel terminal device 130 and the terminal device 120.

[0122] It should also be understood that the embodiments of this application do not limit the number of terminal devices 120, network devices 120, and novel terminal devices 130 that may be included in the communication system 100. For example, terminal device #1 can communicate directly with network device #1, and terminal device #2 and / or terminal device #3 can communicate with network device #1 through peripheral device #1.

[0123] Furthermore, the following section provides a detailed description of how the new terminal device 130 improves the uplink transmission performance of the terminal device 120, which will not be repeated here.

[0124] Figure 3 is a structural schematic diagram of a communication device 300 applicable to an embodiment of this application.

[0125] As shown in Figure 3, the communication device 300 includes peripheral devices and a communication module. The peripheral devices are products used in conjunction with the first device; the communication module is connected to the peripheral devices, and the first device communicates with the second device through the communication module.

[0126] The communication module includes an antenna array, which satisfies a first condition; the first condition includes at least one of the following:

[0127] The antenna gain of the antenna array is higher than that of the first device; the antenna coverage of the antenna array is greater than that of the first device; and the antenna radiation efficiency of the antenna array is higher than that of the first device.

[0128] For example, peripheral devices may include fill lights, brackets, or protective cases, etc. This application embodiment does not limit the type or function of peripheral devices.

[0129] It should be understood that the communication module is connected to the peripheral device in two ways: the communication module may be located inside the peripheral device (e.g., the communication module is integrated into the peripheral device), or the communication module may be located outside the peripheral device (e.g., the communication module and the peripheral device are connected by a connector). This application embodiment does not limit the scope of the connection.

[0130] In this configuration, integrating the communication module into the peripheral device allows for a more compact structure; the superior antenna performance compared to the first device (e.g., the terminal device) enhances the wireless signal of the first device, thereby improving its uplink transmission performance. Simultaneously, the peripheral device retains its original functionality.

[0131] In one possible implementation, the antenna array includes at least one bidirectional antenna; the at least one bidirectional antenna includes a first directional antenna and a second directional antenna. A first end of the first directional antenna is connected to a first end of the second directional antenna via a power divider. That is, the first directional antenna and the second directional antenna are designed back-to-back.

[0132] In this case, the bidirectional antenna ensures coverage in two side firing directions through two directional antennas with opposite directions. Compared with the single omnidirectional antenna in the current technology, the antenna gain of the bidirectional antenna is improved by about 2 to 3 dB.

[0133] Optionally, the first directional antenna and the second directional antenna share a reflector.

[0134] Optionally, the first directional antenna and the second directional antenna are fed by probes.

[0135] In this case, the first and second directional antennas have a more compact structure, which facilitates conformal design with the surrounding structure.

[0136] Optionally, when the antenna array includes multiple bidirectional antennas, the ports of each bidirectional antenna can be connected to the radio frequency module via an analog beamforming device (e.g., a phase-shifting network) to adjust the antenna radiation direction, thereby achieving beam scanning. The phase shifter can adjust the beam direction of the array antennas, improving the coverage and communication quality of the wireless communication system.

[0137] Optionally, the antenna array further includes at least one third directional antenna; each of the at least one third directional antenna is perpendicular to each of the at least one bidirectional antenna.

[0138] In this situation, directional antennas can be used to fill in coverage blind spots after the bidirectional antenna array is assembled, thereby improving the coverage effect.

[0139] Optionally, each of the at least one bidirectional antenna is arranged in a ring array.

[0140] In this case, assembling bidirectional antennas into an array has a beamforming effect, increasing beam gain, and further improving antenna gain compared to a single bidirectional antenna.

[0141] It should be noted that the at least one bidirectional antenna can also be an array of other shapes. For example, the array of at least one bidirectional antenna can be related to the specific shape of the peripheral device, or it can be unrelated to the specific shape of the peripheral device. This application embodiment does not limit this.

[0142] Optionally, the first directional antenna, the second directional antenna, and / or the third directional antenna are E-shaped patch antennas; or, the first directional antenna, the second directional antenna, and / or the third directional antenna are grid antennas.

[0143] It should be noted that the "grid antenna" can be an E-type patch antenna that has been gridded to obtain an E-type grid antenna; or it can be a grid antenna structure different from the E-type. In addition, the "grid" in the grid structure or gridding can be a square grid or a grid of other shapes. This application embodiment does not limit the grid shape.

[0144] In this context, the slotted or hollowed-out design of the antenna can improve the antenna bandwidth and reduce the impact of the antenna on the original functions of peripheral devices, allowing the antenna structure to be conformally designed with the peripheral devices.

[0145] It should be noted that the first directional antenna, the second directional antenna, and / or the third directional antenna may also be radiating structures of other shapes, and this application embodiment does not limit this.

[0146] In one possible implementation, the communication device 300 (or peripheral device) is a fill light; the reflector is located on the dielectric substrate on which the fill light strip is located; the at least one bidirectional antenna is arranged in a ring array, including: the at least one bidirectional antenna is arranged in a ring array along the light strip.

[0147] It should be noted that the at least one bidirectional antenna can be arranged in a ring array to cover a portion of the fill light; or it can cover the entire aperture of the fill light to form a closed loop. This application embodiment does not limit this.

[0148] In this configuration, the antenna array structure is shared with the supplementary lighting structure, which can improve antenna gain while reducing the impact of the light strip circuit on the antenna. When the first directional antenna, the second directional antenna, and / or the third directional antenna are grid antennas, the influence of the antenna structure on the light transmittance of the supplementary lighting can also be reduced.

[0149] Figure 4 is a schematic diagram of a novel terminal device 400 applicable to an embodiment of this application.

[0150] It should be noted that the new terminal device 400 includes peripheral device 410 and communication device 420.

[0151] For ease of understanding, Figure 4 uses peripheral device 410 as an example of a fill light, and does not constitute a limitation on the types of novel terminal devices and peripheral devices in the embodiments of this application.

[0152] Figure 4(a) shows the structure of a fill light 410 commonly used in the present technology.

[0153] The supplementary light 410 may include a lampshade 411, a light strip 412, a dielectric substrate 413, a circuit 414, and a housing 415. The light strip 412 and / or the circuit 414 may be located on the dielectric substrate 413, and the lampshade 411 and the housing 415 may together form a space for placing the light strip 412, the dielectric substrate 413, and the circuit 414.

[0154] Optionally, the fill light 410 may also include a fill light bracket 416 and / or a terminal equipment bracket 417.

[0155] It should be noted that the communication device 420 integrates wireless signal forwarding functionality, enabling wireless communication capabilities to be introduced into the supplementary lighting. This allows the terminal device to enhance antenna performance through new terminal equipment, thereby improving uplink transmission performance. The communication function of the communication device 420 is implemented based on the antenna structure 430.

[0156] Figure 4(b) shows a schematic diagram of an antenna structure 430 applied to a peripheral device 410.

[0157] As shown in the figure, the antenna structure 430 may include a directional antenna 431 and a bidirectional antenna 432. Multiple antennas are integrated into the supplementary light 410 (for example, they may be integrated into the lamp cover 411, on the dielectric board 413, or in the housing 415). Through the diversity effect of the radiation patterns of different antennas, a uniform spherical coverage is formed, which enhances the antenna gain and thus complements the performance of the antenna of the terminal device, realizing a novel antenna structure for the terminal device 400.

[0158] Specifically, the black triangle represents the directional beam generated by the directional antenna 431, with the beam direction pointing towards the end (or, as can be understood, towards the outside of the fill light ring shown in Figure 4(b)). For example, the directional antenna located to the left of the fill light 410 shown in Figure 4(b) has its beam direction parallel to the plane where the fill light 410 is located, pointing to the left (outward).

[0159] The white triangles represent the bidirectional beam generated by the bidirectional antenna 432, with the beam direction covering either upward or downward perpendicular to the plane (the plane where the ring of the supplementary light 410 is located, which can also be understood as the plane shown in Figure 4(b)). For example, the bidirectional antenna shown in Figure 4(b) has its beam direction perpendicular to the front of the supplementary light 410, both upward and downward.

[0160] It should be noted that the number and array configuration of the directional antenna 431 and the bidirectional antenna 432 are shown in (b) in the figure only as an example and do not constitute a limitation on the embodiments of this application.

[0161] Furthermore, the specific structures of the directional antenna 431 and the bidirectional antenna 432 will be described in detail in Figures 5-7 below, and will not be repeated here.

[0162] Figure 5 is a structural schematic diagram of an antenna 500 applicable to an embodiment of this application.

[0163] Figure 5(a) shows a schematic diagram of a directional antenna 500A applicable to an embodiment of this application. As shown, the directional antenna 500A can be an E-shaped patch antenna, with bandwidth improved by slotting the patch.

[0164] It should be noted that the directional antenna 500A can also be a radiating structure of other shapes, and this application embodiment does not limit this.

[0165] Optionally, the directional antenna 500A has a length of 33mm and a width of 25.3mm, and the probe is located at the center of the directional antenna 500A.

[0166] Figure 5(b) shows a schematic diagram of the structure of a bidirectional antenna 500B applicable to an embodiment of this application. As shown, the bidirectional antenna 500B includes two directional antennas 500A (e.g., directional antenna 500A#1 and directional antenna 500A#2), with the back sides of directional antenna 500A#1 and directional antenna 500A#2 facing each other (i.e., the two directional antennas are designed back to back), and the two are connected by a power divider.

[0167] Optionally, directional antenna 500A#1 and directional antenna 500A#2 share reflector #1, and directional antenna 500A#1 and directional antenna 500A#2 are fed through probes.

[0168] Optionally, reflector #1 can be located on the medium plate where the fill light strip is located, thereby increasing the gain in the side-emitting direction.

[0169] Alternatively, reflector #1 can also be shared with the LED structure on the light strip, thereby improving antenna gain while reducing the impact of the light strip circuit on the antenna.

[0170] Optionally, the directional antenna 500A#1 and the directional antenna 500A#2 are spaced 8.508 mm apart.

[0171] It should be understood that the directional antenna 500A and / or the bidirectional antenna 500B can be integrated into the peripheral device 410 shown in FIG. 4 to construct a novel terminal device 400. In other words, the antenna structure 420 in FIG. 4 may include at least one directional antenna 500A and / or at least one bidirectional antenna 500B.

[0172] In one possible implementation, as shown in Figure 5(c), when the peripheral device is a fill light, the antenna gain can be further improved by using multiple bidirectional antennas 500B arranged in a ring array along the aperture of the fill light.

[0173] It should be noted that (c) in Figure 5 is only an example. Multiple bidirectional antennas 500B can be arranged in a ring array to cover a part of the fill light; or they can cover the entire aperture of the fill light to form a closed loop. This application embodiment does not limit this.

[0174] In addition, the multiple bidirectional antennas 500B can also be arranged in other shapes. For example, the arrangement of the multiple bidirectional antennas 500B can be related to the specific shape of the peripheral device, or it can be unrelated to the specific shape of the peripheral device. This application embodiment does not limit this.

[0175] Optionally, the ports of each bidirectional antenna can be connected to the radio frequency module via an analog beamforming device (ABF) (e.g., a phase-shifting network) to adjust the antenna radiation direction, thereby achieving beam scanning.

[0176] For example, as shown in Figure 5(d), when the peripheral device is a supplementary light, multiple bidirectional antennas (e.g., bidirectional antennas 500B#1, 500B#2, and 500B#3) are arranged in a ring array to suit the shape of the peripheral device. Specifically, bidirectional antenna 500B#1 is directly connected to the RF module, bidirectional antenna 500B#2 is connected to the RF module via phase shifter #1, and bidirectional antenna 500B#3 is connected to the RF module via phase shifter #2. By adjusting the radiation direction of bidirectional antennas 500B#2 and 500B#3 using phase shifters #1 and #2, the signal can be distributed more evenly, improving the coverage and communication quality of the wireless communication system.

[0177] In one possible implementation, there are coverage blind spots when using only bidirectional antenna 500B arrays. The coverage effect can be improved by using directional antennas.

[0178] For example, as shown in Figure 5(e), when the peripheral device is a supplementary light, at least one directional antenna 500A can be added to the side of the light strip. The directional antenna 500A can be an E-shaped patch antenna, with bandwidth improved by slotting the patch. Furthermore, the directional antenna 500A can be fed via a probe, resulting in a more compact structure.

[0179] Figure 6 is a radiation pattern of an antenna applicable to an embodiment of this application.

[0180] Figure 6(a) shows the radiation pattern of the bidirectional antenna 500B. As shown in Figure 6(a), the bidirectional antenna 500B ensures coverage in two side firing directions, and the gain of each antenna element is approximately 5.46 dB. Compared with a single omnidirectional antenna in the current technology, the gain of the bidirectional antenna 500B is improved by about 2 to 3 dB.

[0181] Figure 6(b) shows the radiation pattern of a 500B bidirectional antenna ring array. As shown in Figure 6(b), the bidirectional antenna array exhibits superior beamforming performance and increased beam gain. Compared to a single bidirectional antenna element in Figure 6(a), the antenna gain increases from 5.46 dB to 12.4 dB with a 5-element array, representing a gain improvement of approximately 7 dB.

[0182] Figure 6(c) shows the radiation pattern of the directional antenna 500A. Full-wave simulation results show that the directional antenna 500A has a high gain (reaching 9dB).

[0183] It should be noted that (c)-(e) in Figure 5 can be considered as a combination of the different radiation patterns mentioned above, with a relatively compact structure, allowing the corresponding antenna structure to be integrated into peripheral devices. Furthermore, the antenna gain is further improved, achieving a wireless signal enhancement effect, thereby improving the uplink transmission performance of terminal devices used with peripheral devices.

[0184] In one possible implementation, the patch antenna in the directional antenna 500A and / or the bidirectional antenna 500B can also be a grid antenna structure; or, the patch antenna structure in the directional antenna 500A and / or the bidirectional antenna 500B can also be gridded.

[0185] Figure 7 is a schematic diagram of an antenna structure applicable to an embodiment of this application.

[0186] As shown in Figure 7(a), the patch antenna can be a mesh structure, where black represents a conductor and white represents a transparent dielectric or a hollow structure. The shape of the patch antenna is not limited in this embodiment.

[0187] As shown in Figure 7(b), the bidirectional and / or directional antennas in Figures 5 and / or 6 can also be meshed. For example, the E-type patch antennas in directional antenna 500A and / or bidirectional antenna 500B can be retained and meshed to obtain an E-type mesh antenna.

[0188] It should be noted that the "mesh" in the mesh structure or meshing can be a square mesh as shown in Figure 7, or a mesh of other shapes. This application embodiment does not limit the shape of the mesh.

[0189] The grid antenna shown in Figure 7 can improve antenna gain while reducing the impact on the original functions of peripheral devices, allowing the antenna structure to be conformally designed with peripheral devices.

[0190] For example, when the peripheral device is a supplementary light, the influence of the antenna structure on the light transmittance of the supplementary light can be reduced. Furthermore, compared to traditional grid antenna structures, the antenna structure shown in Figure 7 can also be adapted to produce a specific radiation pattern for the supplementary light.

[0191] It should be understood that in some scenarios, the positions of the novel terminal devices shown in Figures 3 and 4 are relatively fixed (for example, when the novel terminal device is a fill light, after the user adjusts the angle and positional relationship between the fill light and the terminal device, the positional relationship between the two will not be adjusted again for a period of time). In this case, the channel environment between the novel terminal devices changes relatively slowly. In one possible implementation, the channel measurement overhead can also be reduced by using the positional information between the novel terminal devices and the terminal devices.

[0192] Figure 8 is a schematic diagram of a communication method 800 applicable to an embodiment of this application.

[0193] It should be understood that the embodiments shown below do not particularly limit the specific structure of the execution subject of the method provided in the embodiments of this application. As long as it is possible to communicate according to the method provided in the embodiments of this application by running a program that records the code of the method provided in the embodiments of this application, for example, the execution subject of the method provided in the embodiments of this application can be a first device (e.g., a terminal device) and a second device (e.g., the novel terminal device 130 shown in FIG2, the communication device 300 shown in FIG3, or the novel terminal device 400 shown in FIG4); or, it can be a functional module in the first device and the second device that can call and execute the program.

[0194] Without loss of generality, the communication method provided in the embodiments of this application will be described in detail below using the interaction between the first device and the second device as an example.

[0195] It should be understood that Figure 8 illustrates the steps or operations of the communication method, but these steps or operations are merely examples. Other operations or variations of the operations shown in Figure 8 may also be performed in the embodiments of this application.

[0196] Method 800 may include the following steps:

[0197] S801: The second device sends first configuration information to the first device; correspondingly, the first device receives the first configuration information from the second device.

[0198] The first configuration information includes first beam information and first position information.

[0199] The second device includes: an antenna array, the antenna array satisfying a first condition; the first condition includes at least one of the following: the antenna gain of the antenna array is higher than the antenna gain of the first device; the antenna coverage area of ​​the antenna array is greater than the antenna coverage area of ​​the first device; the antenna radiation efficiency of the antenna array is higher than the antenna radiation efficiency of the first device.

[0200] Optionally, the first beam information is information about a beam that can be used for communication between the first device and the second device. For example, it may include beam measurement set information and / or beam grouping information. The beam measurement set information is used to indicate multiple beams used for beam measurement, and the beam grouping information is used to indicate the group number of multiple beam groups. The beams and / or beam groups may be predefined or obtained through beam measurement. This application embodiment does not limit the content of the first beam information.

[0201] Optionally, the first location information is the reference location information of the first device. For example, it could be the location information of the first device when the second device last established a connection with the first device; or it could be predefined location information; or it could be a null value. This application embodiment does not limit the content of the first location information.

[0202] Optionally, the first beam information is determined based on the first position information.

[0203] Optionally, the first configuration information can be transmitted via semi-static signaling; or it can be transmitted via radio resource control signaling, media access control-control element signaling, or broadcast, and the embodiments of this application do not limit this.

[0204] Optionally, before step S801, method 800 further includes S801a-S801c:

[0205] S801a: The first device sends a first request message to the second device; correspondingly, the second device receives the first request message from the first device.

[0206] The first request information is used to request the establishment of a connection with the second device.

[0207] S801b: The second device sends a first sensing signal to the first device; correspondingly, the first device receives the first sensing signal from the second device.

[0208] The first sensing signal is used to detect the location of the first device.

[0209] In one possible implementation, the first location information in step S801 is determined based on the location of the first device detected by the first sensing signal.

[0210] S801c: The first device sends a first reference signal to the second device; correspondingly, the second device receives the first reference signal from the first device.

[0211] The first reference signal is used for channel measurement between the first device and the second device, and can also be referred to as a pilot or pilot sequence.

[0212] It should be noted that the specific details of the reference signal used for channel measurement can be found in descriptions in the prior art, and this application does not limit this aspect. Furthermore, this application does not limit the specific method of time-frequency multiplexing, frequency-division multiplexing, or code-division multiplexing of the first reference signal.

[0213] Specifically, the second device can measure (e.g., calculate beam quality) a corresponding beam based on a reference signal transmitted by at least one beam or beam group, and select a beam for communicating with the first device based on the beam measurement solution.

[0214] For example, beam quality can be RSRP or SINR, etc.

[0215] S802: The first device sends first information to the second device; correspondingly, the second device receives the first information from the first device.

[0216] The first information is determined based on the first location information and is used to indicate whether the location of the first device has changed.

[0217] Optionally, the first information is determined based on the first location information.

[0218] In one possible implementation, the first device can determine its current position information (i.e., the second position information) based on its inertial navigation system, determine whether the position of the first device has changed based on the relationship between the first position information and the second position information, and indicate the result to the communication device through the first information.

[0219] For example, the first information is determined based on the first location information and the second location information, and the second location information is determined based on the inertial navigation system of the first device; when the first location information is the same as the second location information, or the absolute value of the coordinate difference between the first location information and the second location information is less than a first value, the first information indicates that the position of the first device has not changed; when the first location information is different from the second location information, or the absolute value of the coordinate difference between the first location information and the second location information is greater than the first value, the first information indicates that the position of the first device has changed.

[0220] It should be noted that the first value can be a predefined value; or it can be determined by the first device itself; or it can be sent to the first device by other devices. This application embodiment does not limit the method of obtaining the first value or its specific value.

[0221] S803: When the first information indicates that the position of the first device has not changed, the first device communicates with the second device based on the first beam information.

[0222] It should be understood that, in conjunction with the structure shown in Figure 2, the second device (i.e., the novel terminal device 130 shown in Figure 2) may include a short-range module, a cellular module, and a wired connection module, so that the second device can establish a wired connection and / or a wireless connection with the first device and communicate based on the wired connection and / or the wireless connection.

[0223] It should be noted that the specific process of communication between the first device and the second device can be referred to the relevant descriptions in the current technology, and the embodiments of this application do not limit it.

[0224] In this case, by carrying the first location information in the first configuration information, the first device can determine whether its own position has changed based on the first location information. If it has not changed, the first device and the second device can communicate based on the first beam information corresponding to the first location information without having to perform beam measurement, thereby reducing system overhead.

[0225] Optionally, when the first information indicates a change in the location of the first device, the second device and the first device will re-perform sensing detection and channel measurement. That is, method 800 further includes steps S803a-S803b:

[0226] S803a: The second device sends a second sensing signal to the first device; correspondingly, the first device receives the second sensing signal from the second device.

[0227] The second sensing signal is used to detect the position of the first device. The second sensing signal is similar to the first sensing signal in step S801b, and will not be described in detail here.

[0228] S803b: The first device sends a second reference signal to the second device; correspondingly, the second device receives the second reference signal from the first device.

[0229] The second reference signal is used for channel measurement between the first device and the second device. The second reference signal is similar to the first reference signal in step S801c, and will not be described in detail here.

[0230] To facilitate understanding of the above embodiments provided in this application, the following points are made.

[0231] (1) In the embodiments of this application, "instruction" may include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information for the purpose of indicating A, it can be understood that the instruction information carries A, directly indicates A, or indirectly indicates A.

[0232] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent. Furthermore, the information to be instructed can be sent as a whole or divided into multiple sub-information pieces, and the sending period and / or timing of these sub-information pieces can be the same or different.

[0233] (2) In this application, "send" and "receive" indicate the direction of signal transmission.
