[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on March 30, 2024, with application number 202410389292.6 and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of mobile communication technologies, and in particular to a communication method and device. Background Art

[0004] With the advancement of communication technology, the amount of data carried in communication signals has increased. For example, high-order modulation of radio frames can be used to increase the amount of data carried by the frames. However, high-order modulation of radio frames may reduce the transmit power of the radio frames, thereby limiting signal coverage. Using low-order modulation to maintain higher transmit power may reduce the amount of data carried by the radio frames.

[0005] Therefore, how to strike a balance between the transmission power of wireless frames and the amount of data carried is a problem that needs to be solved. Summary of the Invention

[0006] The embodiments of the present application provide a communication method and apparatus to balance the transmission power and the amount of data carried by a wireless frame.

[0007] In a first aspect, an embodiment of the present application provides a communication method, which can be executed by a network device, such as a base station, a relay station, or an access point, or by a chip in such devices, and is not limited in this application. The method includes: using a first power to send control signaling in a first symbol portion of a radio frame, the first symbol portion including at least one continuous symbol used to send control signaling; using a second power to send data in a second symbol portion of the radio frame, the second symbol portion including at least one continuous symbol used to send data; and including a third symbol portion between the first symbol portion and the second symbol portion, the third symbol portion being used to enable the network device to switch from the first power to the second power, the third symbol portion including at least one continuous symbol.

[0008] Using this method, network devices can reserve the third symbol portion to switch from the first power to the second power, allowing the power used to send control signaling and the power used to send data to be the same or different, thereby balancing the transmit power and data volume of the radio frame. For example, when the first power is higher than the second power, control signaling can be sent at the higher power to ensure greater signal coverage, while data can be sent at a relatively lower power, enabling high-order modulation of the data and increasing the amount of data transmitted.

[0009] In one implementation, the third symbol portion can be a symbol used to transmit data, or it can be a symbol used to transmit control signaling. Using the above method, the reserved third symbol portion is relatively flexible. That is, a symbol portion used to transmit data can be reserved as the third symbol portion for power conversion, or a symbol portion used to transmit control signaling can be reserved as the third symbol portion for power conversion.

[0010] In one embodiment, when the third symbol part is a symbol for sending data, the first power and the second power may satisfy any one of the following: the third power is less than or equal to the second power, and the second power is equal to the fourth power, and the fourth power is less than or equal to the first power; the above-mentioned third power is the transmission power when sending data in the third symbol part; the fourth power is the maximum value of the third power in multiple consecutive wireless frames; the third power is equal to the second power, and the second power is less than or equal to the fourth power, and the fourth power is less than or equal to the first power; the first power is less than or equal to the third power, and the third power is equal to the second power, and the second power is less than or equal to the fourth power; the third power is less than or equal to the second power, and the second power is equal to the fourth power, and the fourth power is greater than or equal to the first power.

[0011] By adopting the above method, by adjusting the first power and the second power, different signal coverage ranges can be achieved while ensuring the amount of transmitted data, and the transition from the first power to the second power can be achieved through the third power.

[0012] In one embodiment, when the third symbol part is a symbol for sending control signaling, the communication method also includes: no data or control signaling is sent in the third symbol part; the first power and the second power can satisfy any one of the following: the fourth power is less than or equal to the second power, and the second power is equal to the first power; the fourth power is the maximum value of the third power in multiple consecutive wireless frames, and the third power is the transmission power when the control signaling is sent in the third symbol part; the fourth power is greater than or equal to the second power, and the second power is equal to the first power; the fourth power is equal to the second power, and the second power is less than the first power; the second power is equal to the third power, and the fourth power is greater than or equal to the first power.

[0013] Using this method, different signal coverage ranges can be achieved by adjusting the first and second powers, even when no data or control signaling is transmitted in the third symbol portion. The third power is then used to transition from the first power to the second power. Furthermore, since no information (data or control instructions) is transmitted in the third symbol portion, any impact on the transmission quality of the information transmitted in the third symbol portion due to power conversion can be avoided.

[0014] In another embodiment, when the third symbol part is a symbol for sending control signaling, the communication method also includes: sending control signaling in the third symbol part; the first power and the second power can satisfy any one of the following: the fourth power is equal to the second power, and the second power is less than or equal to the first power; the fourth power is the maximum value of the third power in multiple consecutive wireless frames, and the third power is the sending power when the control signaling is sent in the third symbol part; the fourth power is equal to the second power, and the second power is greater than or equal to the first power; the third power is less than or equal to the second power, and the second power is equal to the fourth power, and the fourth power is less than or equal to the first power; the second power is equal to the third power, and the fourth power is greater than or equal to the first power.

[0015] By adopting the above method, different signal coverage ranges can be achieved by adjusting the first power and the second power when sending control signaling through the third symbol part, and the transition from the first power to the second power can be achieved through the third power.

[0016] In one embodiment, the communication method further includes: sending first indication information, the first indication information being used to indicate a difference between the first power and the second power. Using this method, by sending the difference between the first power and the second power, upon receiving control signaling, the terminal can promptly determine the power used by the network device to transmit data based on the transmit power of the control signaling, thereby enabling the terminal to promptly receive data transmitted by the network device in the second symbol portion using the correct power.

[0017] In one embodiment, the communication method further includes: transmitting data in the third symbol portion. Using the above method, the network device transmits data in the third symbol portion, so that when performing power switching in the third symbol portion, the symbols in the third symbol portion can be fully utilized. This allows the symbols in the third symbol portion to perform power switching while carrying data with a lower modulation order, thereby avoiding waste of symbol resources.

[0018] In one embodiment, the communication method further includes: sending second indication information, the second indication information being used to indicate a modulation order used for data sent in the third symbol portion. Using this method, indicating the modulation order used for data sent in the third symbol portion can ensure that the terminal, based on the second indication information, more accurately demodulates the data sent by the network device in the third symbol portion.

[0019] In one embodiment, the communication method further includes: transmitting third indication information, where the third indication information is used to indicate the number and / or position of at least one symbol included in the third symbol portion. Using the above method to indicate the number and / or position of at least one symbol included in the third symbol portion enables the terminal to timely adjust the power of received data based on the number and / or position of at least one symbol included in the third symbol portion.

[0020] In one embodiment, the communication method further includes: using a third power to send control signaling or data in the third symbol portion.

[0021] In one embodiment, the communication method further includes: receiving fourth instruction information, the fourth instruction information being used to instruct data to be sent in the third symbol portion. In this way, the network device can, under the instruction of the terminal device, determine that it is possible to use the third symbol portion to send data when data is sent in the third symbol portion, thereby enabling the network device to use the third symbol portion to send data in advance based on a negotiation result with the terminal device.

[0022] In one embodiment, the communication method further includes: receiving fifth indication information, wherein the fifth indication information is used to indicate that no information (data or control instruction) is sent in the third symbol part, and no information is sent in the third symbol part.

[0023] By adopting the above method, the information transmission status of the third symbol part can be controlled through the pre-set indication information, and the third symbol part can be used flexibly.

In the embodiments of the present application, "of", "corresponding, relevant" and "corresponding" can sometimes be used interchangeably. It should be noted that when the distinction between them is not emphasized, the meanings to be expressed are consistent.

[0153] The following first describes the application scenarios of the embodiments of the present application.

[0154] The technical solutions in the embodiments of the present application can be applied to various communication systems, such as universal mobile telecommunications system (UMTS), wireless local area network (WLAN), wireless fidelity (Wi-Fi) system, 4th generation (4G) communication system, such as long term evolution (LTE) system, 5G communication system, such as new radio (NR) system, vehicular wireless short-range communication system, and future evolved communication systems, such as sixth generation (6G) mobile communication system.

[0155] To facilitate understanding of the embodiments of the present application, the communication system applicable to the embodiments of the present application is first described in detail using the communication system shown in Figure 1a as an example. As shown in Figure 1a, the communication system 1000 includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet. The wireless access network 100 may include at least one network device, such as 110a and 110b in Figure 1a, and may also include at least one terminal device, such as 120a-120j in Figure 1a. 110a is a base station, 110b is a micro station, 120a, 120e, 120f, and 120j are mobile phones, 120b is a car, 120c is a gas pump, 120d is a home access point (HAP) arranged indoors or outdoors, 120g is a laptop computer, 120h is a printer, and 120i is a drone.

[0156] In Figure 1a, terminal devices can be connected to network devices, and network devices can be connected to core network devices in the core network. The core network devices and network devices can be independent and distinct physical devices, or they can integrate the core network device's functions and the network device's logical functions into the same physical device. Alternatively, a single physical device can integrate some core network device functions and some network device functions. Terminal devices and network devices can be connected to each other via wired or wireless means. Figure 1a is merely a schematic diagram; the communication system may also include other devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1a.

[0157] It is understood that the technical solutions in the embodiments of the present application can also be applied to other communication systems, and the corresponding names can also be replaced with the names of corresponding functions in other communication systems. Figure 1a is only a simplified schematic diagram for ease of understanding. The communication system may also include other devices, which are not shown in Figure 1a.

[0158] Exemplarily, the technical solutions of the embodiments of the present application can be applied to but not limited to wireless short-range communication systems and wireless communication systems that support longer-range transmission (such as 1 to 18 km, more than 18 km) (such as the next-generation GT network wireless communication system). Among them, the wireless short-range communication system mainly includes vehicle-mounted wireless short-range communication technology (also known as Star Flash 1.0 technology), which has the advantages of ultra-low latency, ultra-high reliability, and precise synchronization, and is suitable for applications in scenarios such as smart cars, smart homes, smart terminals, and smart manufacturing. For example, applications in smart car scenarios include: immersive in-vehicle sound field & noise reduction, wireless interactive projection, and 360-degree panoramic view, which can achieve an immersive interactive experience and improve vehicle safety.

[0159] Wireless communication systems that support longer-distance transmission (e.g., 1-18 km) mainly include next-generation GT network wireless communication systems, such as the GT1.5 network wireless communication system and the GT2.0 network wireless communication system. These systems are not only suitable for communication scenarios with low latency requirements, such as the aforementioned in-vehicle communications and industrial control scenarios, but can also be used in communication scenarios with low latency requirements.

[0160] In some possible implementations, the above-mentioned communication system may be used in combination with a mobile communication system, for example, the mobile communication system includes but is not limited to the fourth generation (4G) communication system (for example, the long term evolution (LTE) system), the fifth generation (5G) communication system (for example, the new radio (NR) system), and future mobile communication systems such as the sixth generation (6G) mobile communication system.

[0161] For ease of understanding, the relevant technologies involved in the embodiments of this application are first introduced below.

[0162] (1) In the GT1.0 protocol corresponding to the Star Flash 1.0 technology, there is uplink transmission and downlink transmission between the G node and the T node. Among them, uplink transmission is achieved through the T link, which is the link between the T node and the G node, also known as the uplink; downlink transmission is achieved through the G link, which is the link between the G node and the T node, also known as the downlink.

[0163] In the GT1.0 communication network, as shown in Figure 1b, a superframe with a length of 1ms is used for data transmission between G nodes and T nodes. This superframe structure is mainly suitable for business scenarios with short-distance communication and low latency. The 1ms superframe contains 48 radio frames, and the length of each radio frame is 20.83 microseconds (us). Due to the system sampling frequency F s is 30.72 megahertz (MHz), so a 1ms superframe is 30720×T s , a 20.83us wireless frame is 640×T s ,in,

[0164] Each wireless frame includes multiple cyclic prefix (CP)-orthogonal frequency division multiplexing (OFDM) symbols, that is, the CP-OFDM symbol contains a cyclic prefix part and a valid data part in the time domain. The length of the valid data part is 64×T s Among them, CP includes 5×T s The length of the conventional CP and 14×T s The length of the extended CP, the corresponding CP-OFDM symbol includes a length of 69×T based on the length of the conventional CP s CP-OFDM symbol, and the length of 78×T based on the length of the extended CP s In order to avoid confusion, the embodiment of the present application uses symbol as the abbreviation of CP-OFDM symbol.

[0165] G-link transmission and T-link transmission use different symbols in the radio frame. The symbols used for G-link transmission are called G symbols, and the symbols used for T-link transmission are called T symbols. A radio frame consists of one or more G symbols, a first switching interval (GAP1), one or more T symbols, and a second switching interval (GAP2). GAP1 is used to instruct the T node to switch from receiving downlink data to sending uplink data, while GAP2 is used to instruct the T node to switch from sending uplink data to receiving downlink data.

[0166] In the case of using conventional CP, GAP1+GAP2=44×T s ; When using extended CP, GAP1+GAP2=47×T s .

[0167] In the vehicle-mounted wireless short-range communication system, the network device may be a G (grant) node, and the terminal device may be a T (terminal) node.

[0168] (2) G node, which can be a network device or a management node, is usually a node that sends data scheduling information in a communication system.

[0169] The management node is located on the network side of the above-mentioned communication system to help the terminal node achieve wireless access, and is a device with wireless transceiver functions or a chip or chip system that can be set in the device. The management node includes but is not limited to: a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP or transmission point, TP), a next-generation NodeB (gNB), a next-generation base station in the sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access point (AP) in a wireless fidelity (Wi-Fi) system. The management node can be a macro base station, a micro base station or an indoor station, a relay node or a donor node, an open radio access network (ORAN), or a wireless controller in a centralized radio access network (CRAN) scenario. The management node can also be one or a group of antenna panels (including multiple antenna panels) of a fifth-generation (5G) base station, or a network node that constitutes a gNB, TRP, TP, or transmission measurement function (TMF), such as a central unit (CU), distributed unit (DU), CU-control plane (CP), CU-user plane (UP), or radio unit (RU), or a roadside unit (RSU) with base station functionality. Optionally, the management node can also be a server, wearable device, vehicle, or onboard equipment. For example, the management node in vehicle-to-everything (V2X) technology can be an RSU. Alternatively, the management node can be a control unit in an unmanned vehicle, a central controller in a smart factory or smart home, or a handheld or automated control remote sensor for an aircraft. Optionally, the management node can also be a central control panel or other control device, such as a drone controller or a control unit in industrial control. All or part of the functions of the management node in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).The management node in this application may also be a logical node, a logical module or software that can implement all or part of the management node functions.

[0170] The embodiment of the present application does not limit the form of the management node. The device used to implement the functions of the management node can be a management node; it can also be a device that can support the management node to implement the functions, such as a chip system. The device can be installed in the management node or used in conjunction with the management node.

[0171] (3) T-node: T-node can also be called terminal node, which is usually a node in the communication system that receives data scheduling information and sends data according to the data scheduling information.

[0172] A terminal node is a device, equipment, module, chip or chip system with transceiver functions. The terminal node may also be called user equipment (UE), access terminal, subscriber unit, user station, mobile station (MS), mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal nodes in the embodiments of the present application may be mobile phones, cellular phones, smart phones, tablet computers, wireless data cards, personal digital assistants (PDAs), wireless modems, handheld devices (handsets), laptop computers, machine type communication (MTC) terminals, computers with wireless transceiver functions, virtual reality (VR) terminals, augmented reality (AR) terminals, smart home appliances (e.g., refrigerators, televisions, air conditioners, electric meters, etc.), intelligent robots, robotic arms, workshop equipment, wireless terminals in unmanned driving, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, vehicle-mounted terminals, roadside units with terminal functions, etc. The terminal node of the present application may also be an onboard module, onboard module, onboard component, onboard chip or onboard unit built into a vehicle as one or more components or units. The terminal node may also be other devices with terminal functions. For example, the terminal node may also be a device that functions as a terminal in device-to-device (D2D) communication.

[0173] The embodiments of this application do not limit the device form factor of the terminal. The device used to implement the function of the terminal node can be a terminal node; it can also be a device that can support the terminal node to implement the function, such as a chip system. The device can be installed in the terminal node or used in conjunction with the terminal node. In the embodiments of this application, the chip system can be composed of a chip or can include a chip and other discrete devices.

[0174] The communication system composed of the above-mentioned G nodes and T nodes can be a Star Flash communication system or a Bluetooth communication system. It should be pointed out that the solutions in the embodiments of the present application can also be applied to other communication systems, and the corresponding names can also be replaced by the names of corresponding functions in other communication systems.

[0175] (4) In the embodiments of the present application, “sending information to...(terminal device or module)” and “sending information to...(terminal device or module)” can be understood as the destination end of the information being the terminal device or module. This can include sending information to the terminal device directly or indirectly. “Receiving information from...(terminal device or module)” and “receiving information from...(terminal device or module)” can be understood as the source end of the information being the terminal device, which can include receiving information from the terminal device directly or indirectly. The information may be processed as necessary between the source end and the destination end of the information transmission, such as format changes, etc., but the destination end can understand the valid information from the source end. Similar expressions in this application can be understood similarly and will not be repeated here.

[0176] (5) Wireless Frame

[0177] A radio frame is a type of frame transmitted via wireless communication and is a unit of data transmission. A radio frame consists of multiple symbols, which can be divided into different parts. Different symbols perform different functions or carry different information.

[0178] In this embodiment, a radio frame may include at least one symbol portion, and each symbol portion may include at least one symbol. Furthermore, each symbol may be a time-frequency resource symbol including multiple bits. A corresponding cyclic prefix (CP) may be set between symbols used to transmit uplink data and symbols used to transmit downlink data.

[0179] Classification of wireless frames:

[0180] Depending on whether the transmission direction of the radio frame is from the network device to the terminal or from the terminal device to the network device, the radio frame can be divided into: uplink radio frame (grant frame, GF), downlink radio frame (terminal frame, TF), special radio frame (special frame, SF). Among them, the uplink radio frame is a radio frame sent from the terminal device to the network device, and the information carried therein is uplink information. Uplink information is information sent by the terminal device to the network device. Downlink radio frame is a radio frame sent from the network device to the terminal device, and the information carried therein is downlink information. Downlink information is information sent by the network device to the terminal device. Special radio frames may carry uplink information and / or downlink information. When a special radio frame carries uplink information and downlink information at the same time, a gap symbol (gap) is usually included between the uplink information and the downlink information.

[0181] (6) Wireless frame structure

[0182] The structure of a radio frame includes the structure between multiple radio frames and the structure within a single radio frame.

[0183] (7) Signaling

[0184] The portion of a signal transmitted in a wireless or wired network specifically used to control circuits. Signaling carries information about the nodes involved in wireless communication. Signaling allows different nodes in wireless communication to control the process and ensure normal communication.

[0185] (8) Channel

[0186] A channel used to transmit signaling. In addition to control signaling, a channel can also transmit data. Channels that use broadcasting are considered broadcast channels. Channels that transmit control signaling are considered control channels.

[0187] Control channels further include broadcast channels, common control channels, and dedicated control channels. Common control channels are used to transmit control signaling and other information required for communication link connections during the call phase. Broadcast channels further include synchronization channels (SCH) and broadcast control channels (BCCH).

[0188] (9) Control signaling

[0189] Control signaling is signaling sent in a control channel, including signaling sent through a broadcast channel, a common control channel, and a dedicated control channel.

[0190] For example, the synchronization channel in the broadcast channel can send control signaling including FTS and STS. The control signaling that can be sent in the common control channel includes CR-IND.

[0191] (10) Data

[0192] Data, also known as service data, corresponds to the functionality of the service used by a user through a terminal device. For example, if a user is using a terminal device to make a call, the data is the voice of the call. If the user is using the terminal to connect to the network, the data is the content requested by the network connection and / or the user. In other words, in a radio frame, data refers to the content other than signaling.

[0193] Figure 3 illustrates a structure between multiple radio frames. Each row in Figure 3 represents a superframe composed of multiple radio frames. In the time domain, the GF, TF, and SF can be configured to repeat according to a certain switching period, resulting in the 11 rows of superframes with different structures shown in Figure 3. Each superframe has a corresponding switching period. As shown in Figure 3, the switching period for the radio frame configuration in rows 1-7 is 1 millisecond (ms), the switching period for the radio frame configuration in rows 8-10 is 0.5 ms, and the switching period for the radio frame configuration in row 11 is 125 microseconds (μs).

[0194] Figure 4 shows the internal structure of the first three radio frames in the fifth row of the superframe in Figure 3. Each radio frame includes multiple orthogonal frequency division multiplexing (OFDM) symbols. As shown in Figure 4, the OFDM symbols included in the first GF of a superframe can specifically carry a first training signal (FTS), a second training signal (STS), broadcast channel (BCH) control signaling, a control resource indicator (CR-IND), grant control information (GCI), and DS.

[0195] Among them, FTS can also be called the primary synchronization sequence, STS can also be called the secondary synchronization sequence, GCI can also be called downlink control information (DCI), and multiple GCIs and DSs can be set. FTS, STS, CR-IND, and GCI are used to carry common control channel control signaling, and BCH is used to carry broadcast channel control signaling. If after the third GF, more DSs are needed to carry downlink data sent to the second device, the DS carrying data can also be carried in the SF shown in Figure 4. Each OFDM symbol includes a cyclic prefix (CP), which can eliminate inter-symbol interference and inter-carrier interference.

[0196] As shown in Figure 4, in a downlink radio frame, multiple control signals, such as the FTS, must be sent before the DS is sent. Figure 4 also shows that the symbols carrying control signaling (i.e., FTS, STS, CR-IND, and GCI in Figure 4) and the symbols carrying data (DS) are continuous. However, the data carried by DS symbols can be increased through higher-order modulation. The current standard for vehicular wireless short-range communication systems supports up to 1024 quadrature amplitude modulation (QAM) for DS data, and the next-generation standard may support up to 4096QAM modulation for data. Compared to short-range communication technologies such as wireless fidelity (Wi-Fi), the coverage of vehicular wireless short-range communication systems is limited by the power of broadcast channels and public control channels. In multi-user scenarios, it is unable to provide coverage for both cell-edge and cell-center users. Similar issues still exist in the second phase of the standard. If the transmission power of all symbols is reduced to avoid conversion between different power levels, the amount of data carried by the symbols will be reduced. Therefore, in related technologies, the DS symbol of a wireless frame may carry high-order modulated data. The increase in the modulation order will lead to a decrease in the transmission power of the data, making the transmission power of the DS symbol lower than the transmission power of the symbol before the DS symbol.

[0197] If there is a large power variation between the transmission powers of two adjacent different symbols when sending consecutive symbols, it will affect the analog device used to send wireless frames and cause nonlinear distortion in the analog device. If there is at least one symbol used to carry data between two adjacent symbols, then the large variation in the transmission power of the two adjacent symbols will affect the quality of the data carried by the DS symbol. Therefore, when sending data symbols, if the transmission power of the DS symbol is relatively low, the analog device needs to perform power backoff before sending the DS symbol so that the transmission power before the DS symbol is aligned with the transmission power of the DS symbol, avoiding the quality of the data carried by the DS symbol being affected by the decrease in the transmission power of adjacent or multiple consecutive symbols. However, if power backoff is performed before sending the DS symbol, the coverage range of the symbol before the DS symbol will be reduced.

[0198] Similarly, if the transmission power of the DS symbol is higher than the transmission power of the symbol before the DS symbol, there will still be inconsistency in the transmission power of consecutive symbols of the wireless frame, and the transmission power of consecutive symbols will need to be switched, which will still affect the quality of the data carried by the DS symbol.

[0199] In view of this, an embodiment of the present application provides a communication method to take into account the coverage range of wireless frames and the data volume requirements for transmission. Figure 2 is a flow chart of a communication method provided by an embodiment of the present application. The communication method can be applied to a Star Flash communication system or a Bluetooth communication system composed of a G node and a T node for illustration. Of course, the subject that executes the G node action in the method can also be a device / module in the G node, such as a chip, chip system, processor, processing unit, circuit, logic module or software in the G node; the subject that executes the T node action in the method can also be a device / module in the T node, such as a chip, chip system, processor, processing unit, circuit, logic module or software in the T node, and the embodiment of the present application does not make specific limitations on this. The following description takes the G node as a network device and the T node as a terminal device as an example.

[0200] As shown in FIG2 , the communication method provided in this application includes steps S21 to S22 shown in FIG2 .

[0201] Step S21: The network device transmits control signaling in a first symbol portion of a radio frame using a first power, where the first symbol portion includes at least one continuous symbol used to transmit control signaling. Accordingly, the terminal device can receive control signaling carried by at least one symbol in the first symbol portion using the first power.

[0202] The first power and first symbol parts in step S21 are introduced below.

[0203] The first power may be the power used by the network device when sending control signaling in the first symbol part. The first symbol part of the radio frame may include multiple OFDM symbols, and each OFDM symbol of the first symbol part may carry control signaling. The first symbol part of the radio frame may be in one radio frame, or may be in two or more consecutive radio frames. The specific amount may be determined based on the number of symbols required for signaling and data, and is not limited in the embodiments of the present application. When the first symbol part is in more than two consecutive radio frames, it can be understood that the network device can send control signaling to the terminal device through more than two radio frames.

[0204] The one or more OFDM symbols included in the first symbol portion of the radio frame may include symbols for carrying the FTS, symbols for carrying the STS, symbols for carrying the BCH, etc. The first symbol portion may also not include symbols for carrying the BCH. In addition, the first symbol portion of the radio frame may also include symbols for carrying the CR-IND.

[0205] The control signaling carried by the first symbol part may include control signaling of a broadcast channel and control signaling of a common control channel.

[0206] Each symbol included in the first symbol part may further include multiple bits, and the bits may carry control signaling.

[0207] Step S22: The network device uses the second power to send data in the second symbol part of the wireless frame, and the second symbol part includes at least one continuous symbol for sending data; a third symbol part is included between the first symbol part and the second symbol part, and the third symbol part is used to enable the network device to switch from the first power to the second power, and the third symbol part includes at least one continuous symbol.

[0208] Correspondingly, the terminal device can use the second power to receive data in the second symbol part of the wireless frame.

[0209] (1) Next, the second symbol part and the second power are introduced.

[0210] The symbols included in the second symbol part may be data symbols (DS) used to carry data. The DS in the second symbol part may carry data or may not carry data.

[0211] The data carried by the second symbol part may be modulated by using quadrature phase shift keying (QPSK), or modulated by using 16QAM, 64QAM, 256QAM, 1024QAM or 4096QAM.

[0212] When the second symbol portion includes multiple symbols for sending data, the modulation orders of the data carried by different symbols may be different. Alternatively, when the second symbol portion includes multiple symbols for sending data, the modulation orders of the data carried by different symbols may be the same.

[0213] The second power is the power at which the network device transmits data in the second symbol portion. In one implementation, the second power may be different from the first power. For example, the second power may be greater than the first power, or the second power may be less than the first power.

[0214] (2) Next, the third symbol part is introduced.

[0215] In one embodiment, the last symbol of the first symbol portion and the first symbol of the third symbol portion may be adjacent, and the last symbol of the first symbol portion and the first symbol of the third symbol portion may be continuous.

[0216] In one embodiment, the last symbol of the third symbol portion and the first symbol of the second symbol portion may be adjacent, and the last symbol of the third symbol portion and the first symbol of the second symbol portion may be continuous.

[0217] In one embodiment, the symbols included in the third symbol portion are symbols that can be used to send data, and the symbols included in the third symbol portion can carry data or not. In another embodiment, the symbols included in the third symbol portion are symbols that can be used to send control signaling, and the symbols included in the third symbol portion can carry control signaling or not.

[0218] In one embodiment, the signal coverage range can be adjusted by configuring the size of the first power. The second power can be greater than or equal to the power required when the second symbol part carries data. The minimum value of the second power is determined according to the modulation order of the data carried by the second symbol part. The higher the modulation order of the data, the more data the symbol carries, and the corresponding second power may be smaller.

[0219] In one embodiment, the first symbol of the first symbol part may belong to the first radio frame, the first symbol of the second symbol part may belong to the second radio frame, and the first symbol of the third symbol part may belong to the third radio frame. The first radio frame, the second radio frame, and the third radio frame may be different radio frames in a superframe, and a superframe may include multiple consecutive radio frames.

[0220] In one embodiment, the symbols of the first symbol part and the symbols of the third symbol part may constitute a plurality of consecutive symbols, and the plurality of consecutive symbols may be symbols in a plurality of consecutive radio frames.

[0221] In one embodiment, the symbols of the third symbol part and the symbols of the second symbol part may constitute a plurality of consecutive symbols, and the plurality of consecutive symbols may be symbols in a plurality of consecutive radio frames.

[0223] FIG5 is a schematic diagram of an example embodiment of the present application. Based on the example shown in FIG2, the third symbol portion can be a symbol used to send control signaling or data. As shown in FIG5, the communication method of this example includes steps S51 to S53.

[0224] Step S51: The network device sends control signaling in a first symbol portion of a radio frame using a first power, where the first symbol portion includes at least one continuous symbol used to send control signaling.

[0225] The implementation of step S51 may refer to step S21 in FIG. 2 .

[0226] Step S52: The network device transmits at least one data or control signaling message in the third symbol portion of the radio frame using the third power. Specifically, at least one consecutive symbol may carry control signaling or data with a relatively low modulation order (less than a preset value). Accordingly, the terminal device receives the data or control signaling message in the third symbol portion of the radio frame.

[0227] When receiving data or control signaling in the third symbol portion, the terminal device performs automatic gain control (AGC) on the receiving gear to achieve optimal performance.

[0228] The third power is introduced below.

[0229] If the third symbol portion includes multiple symbols, the third power may be the maximum power at which the network device transmits information in the third symbol portion. The third power may serve as a transition power between the first power and the second power. Prior to step S52, control signaling or data may be transmitted on at least one consecutive symbol included in the third symbol portion using a power between the first power and the third power, thereby implementing a transition from the first power to the third power.

[0230] In one implementation, the first symbol portion, the second symbol portion, and the third symbol portion may be within multiple radio frames, where the multiple radio frames constitute a superframe. Accordingly, the third power may be the maximum power when the third symbol portion within a superframe carries control signaling or data.

[0231] Step S53: The network device transmits data in a second symbol portion of the radio frame using a second power, where the second symbol portion includes at least one continuous symbol for transmitting data.

[0232] The manner of sending data in the second symbol part in step S53 may refer to step S22 in FIG. 2 .

[0233] When the network device sends data or control signaling in the third symbol part, the terminal device can receive data and control signaling in the third symbol part accordingly; when the network device does not send any information in the third symbol part, the terminal device does not need to perform receiving behavior in the third symbol part accordingly, thereby realizing the functions required in different scenarios.

[0234] (1) The symbols of the third symbol part may be symbols for transmitting data.

[0235] The symbol used to send data may be a power switch reserve symbol (PSRS), as shown in FIG6 .

[0236] In one implementation, the first power and the second power may satisfy any of the following conditions.

[0237] Case 1: Power switching is performed starting from the first symbol of the third symbol part, so that the transmission power when the symbol carries signaling or data transitions from the first power to the second power, the third power is less than or equal to the second power, and the second power is equal to the fourth power, and the fourth power is less than or equal to the first power; the fourth power is the maximum value of the third power in multiple consecutive wireless frames.

[0238] In one implementation, the third power is the maximum transmit power when sending at least one data or control signaling in the third symbol part within a superframe, and the fourth power is the maximum value of the third power within multiple superframes.

[0239] Since a higher first power is used to send the control signaling in the first symbol part in the first situation, the coverage range of the wireless frame is improved, thereby improving the cell coverage capability of the network device.

[0240] Case 2: the third power is equal to the second power, the second power is less than or equal to the fourth power, and the fourth power is less than or equal to the first power.

[0241] The fourth power and switching method are the same as those in case one.

[0242] Since, in case 2, the third power is the maximum transmit power when at least one data or control signaling is transmitted in the third symbol portion within a superframe, the third power is adjusted for each superframe so that the quality of the data carried by the symbols in the second symbol portion is not affected when the first power is switched to the second power. At the same time, an increase in the modulation order of the data carried by the second symbol portion will cause the second power of the transmitted data to decrease. When the power size is set using the method of case 2, the target power (i.e., the third power) for power switching in the third symbol portion varies in different superframes, so that the third power in each superframe can be consistent with the second power in the current superframe, ensuring that the maximum transmit power when transmitting data in the third symbol portion corresponds to the modulation order of the data carried by the second symbol portion in each superframe, thereby ensuring the quality of the data carried by the second symbol portion in each superframe.

[0243] Case 3: the first power is less than or equal to the third power, the third power is equal to the second power, and the second power is less than or equal to the fourth power.

[0244] Since a smaller first power is used in case three, although the coverage of the signaling of the first symbol part is reduced, close coverage of the wireless signal is achieved, mutual interference between different cells is reduced, and confidentiality requirements are met.

[0245] Case 4: the third power is less than or equal to the second power, the second power is equal to the fourth power, and the fourth power is greater than or equal to the first power.

[0246] In case 4, a smaller first power is used to achieve close coverage of wireless signals, reduce mutual interference between different cells, and meet confidentiality requirements.

[0247] The increase in the modulation order of the data carried by the second symbol part will cause the second power when sending data to decrease. When the power size is set in the manner of case four, the target power (i.e., the third power) for power switching of the third symbol part is different in different superframes, so that the third power in each superframe can be consistent with the second power in this superframe, ensuring that the maximum transmission power of the symbols of the third symbol part corresponds to the modulation order of the data carried by the symbols of the second symbol part in each superframe, thereby ensuring the quality of the data carried by the second symbol part in each superframe.

[0248] (2) The symbols in the third symbol portion may be symbols used to send control signaling, and no data or control signaling is sent in the third symbol portion.

[0249] When no data or control signaling is sent in the third symbol part, the symbols included in the third symbol part may carry null grant control information (Null-GCI), as shown in Figure 7. The first power and the second power may satisfy any of the following conditions.

[0250] Case 1: the fourth power is less than or equal to the second power, and the second power is equal to the first power.

[0251] Case 2: the fourth power is greater than or equal to the second power, and the second power is equal to the first power.

[0252] Case 3: the fourth power is equal to the second power, and the second power is less than the first power.

[0253] Case 4: the second power is equal to the third power, and the fourth power is greater than or equal to the first power, and the third power is the transmission power when the control signaling is sent in the third symbol part.

[0254] By adopting the method in (2), the symbols of the third symbol part are used to send control signaling, and the symbols of the third symbol part do not carry data or control signaling, so that when the symbols of the third symbol part are used for power switching, the quality of the data or control signaling carried by the symbols will not be affected.

[0255] (3) The symbols in the third symbol part may be symbols used to send control signaling, and the control signaling sent in the third symbol part is used to instruct power switching.

[0256] The symbol carrying signaling may be GCI, and the signaling carried by GCI is power switch (PS) signaling (PS-GCI), and PS signaling is used to instruct the operation of performing power switching, as shown in Figure 8. The first power and the second power may satisfy any of the following conditions.

[0257] Case 1: the fourth power is equal to the second power, and the second power is less than or equal to the first power.

[0258] Case 2: the fourth power is equal to the second power, and the second power is greater than or equal to the first power.

[0259] Case 3: the third power is less than or equal to the second power, the second power is equal to the fourth power, and the fourth power is less than or equal to the first power.

[0260] Case 4: the second power is equal to the third power, and the fourth power is greater than or equal to the first power.

[0261] By adopting the method in (3), symbols for sending control signaling can be reserved in the third symbol part, and control signaling is sent in the third symbol part, so that after the terminal device receives the control signaling in the symbol, it can perform operations corresponding to the control signaling, thereby making more effective use of the reserved symbols in the third symbol part.

[0262] In the specific implementation of the symbols of the third symbol part of (1)-(3) above, when multiple symbols are reserved in the third symbol part, different third powers can be used for sending data or control signaling in different symbols of the third symbol part. If different third powers are used to send data or control signaling in multiple different symbols in the third symbol part, the power used when sending data or control signaling on symbols close to the first symbol part in the third symbol part is closer to the first power than the power used when sending data or control signaling on symbols close to the second symbol part; similarly, the power used when sending data or control signaling on symbols close to the second symbol part is closer to the second power than the power used when sending data or control signaling on symbols close to the first symbol part.

[0263] Example (2)

[0264] On the basis of the embodiment shown in FIG. 2 , first indication information may also be sent to indicate the power magnitude relationship through the first indication information, and the operation shown in FIG. 9 may be performed.

[0265] Step S91: The network device sends first indication information, where the first indication information is used to indicate a power difference between a first power and a second power.

[0266] Correspondingly, the terminal device receives the first indication information.

[0267] In one implementation, the indication information may be sent via broadcasting, and correspondingly, the terminal device receives the indication information via broadcasting.

[0268] The implementation of step S92 may refer to step S21.

[0269] The implementation of step S93 may refer to step S22.

[0270] By sending the first indication information, the terminal device can know the power difference between the first power and the second power, thereby switching the gear of the signal receiving power.

[0271] Example (3)

[0272] Based on the example shown in FIG5 , third indication information may be sent, and the third indication information indicates the number and / or positions of symbols in the third symbol part, as shown in FIG10 .

[0273] Step S101: The network device sends third indication information, where the third indication information is used to indicate the number and / or position of at least one symbol included in the third symbol part. Correspondingly, the terminal device receives the third indication information.

[0274] The implementation of steps S102 to S104 may refer to steps S51 to S53 shown in FIG. 5 , respectively.

[0275] Through the third indication information, the terminal device can obtain the number and / or position of at least one symbol of the third symbol part, and perform corresponding receiving operations according to the number and / or position of at least one symbol of the third symbol part.

[0276] Example (4)

[0277] Based on the example shown in Figure 2, the symbols of the third symbol part can carry data, and the second indication information is sent in advance. The second indication information is used to indicate the modulation order used for the data sent by the third symbol part, as shown in Figure 11.

[0278] Step S111: The network device sends second indication information, where the second indication information is used to indicate the modulation order used for the data sent in the third symbol part.

[0279] The implementation of step S112 may refer to step S21 in FIG. 2 or step S51 in FIG. 5 .

[0280] Step S113: The network device sends data in the third symbol part.

[0281] Accordingly, the terminal device can receive data in the third symbol part.

[0282] Meanwhile, step S113 may also be implemented using step S53 shown in FIG5 and related methods.

[0283] Step S114: the network device transmits data in a second symbol portion of the radio frame using a second power, where the second symbol portion includes at least one continuous symbol for transmitting data.

[0284] The implementation of step S114 may refer to step S53 in FIG. 5 .

[0285] Through the second indication information, the terminal device can be informed of the modulation order of the data sent through the third symbol part, so that the terminal device can adjust the receiving gear of the terminal device according to the second indication information.

[0286] Example (5)

[0287] Before the network device sends control signaling in the first symbol part, it can determine whether to send or not to send symbols in the third symbol part according to the superframe that the network device is about to send or the rules pre-set at the network device, and execute the steps shown in Figure 12.

[0288] Step S121: If the network device determines not to send symbols in the third symbol part according to the acquired setting rule, it sends fifth indication information, where the fifth indication information is used to indicate that 0 symbols are sent in the third symbol part.

[0289] Step S122: The network device sends control signaling in a first symbol portion of a radio frame using a first power, where the first symbol portion includes at least one continuous symbol used to send control signaling.

[0290] The implementation of step S122 may refer to step S21 in FIG. 2 or step S51 in FIG. 5 .

[0291] Step S123: Use the second power to send data in the second symbol part of the radio frame, where the second symbol part includes at least one continuous symbol for sending data.

[0292] The implementation of step S123 may refer to step S53 in FIG. 5 .

[0293] Step S124: If the network device determines to send symbols in the third symbol part according to the acquired setting rule, it sends fourth indication information, where the fourth indication information is used to indicate that data is carried in at least one symbol sent in the third symbol part.

[0294] Steps S125 to S127 may refer to steps S51 to S53 in FIG. 5 , respectively.

[0295] Based on the example shown in FIG5 , sixth indication information may be sent in advance to indicate the magnitude relationship among the first power, the second power, and the third power.

[0296] Correspondingly, the terminal device can receive the sixth indication information.

[0297] In one possible implementation, any one of the first to sixth indication information may be carried by a master information block (MIB), a system information block (SIB), or downlink control information (DCI). Alternatively, one of the MIB, SIB, and DCI may be used to carry a portion of the first to sixth indication information, and another of the MIB, SIB, and DCI may be used to carry another portion of the first to sixth indication information. Alternatively, the MIB may be used to carry a portion of the first to sixth indication information, the SIB may be used to carry another portion of the first to sixth indication information, and the DCI may be used to carry yet another portion of the first to sixth indication information.

[0298] The network device may broadcast the first indication information, the second indication information, the third indication information, and the fourth indication information to all terminal devices in a broadcast manner through the MIB, SIB, or DCI. Alternatively, the network device may send the first indication information, the second indication information, the third indication information, and the fourth indication information to a specific terminal device through the MIB, SIB, or DCI.

[0299] Correspondingly, the fourth power is the maximum value of the third power within an MIB period, or the fourth power is the maximum value of the third power within an SIB period, or the fourth power is the maximum value of the third power within a DCI broadcast period.

[0300] Exemplarily, the network device broadcasts the modulation order of the data carried by the symbols of the third symbol part, and the symbols of the third symbol part use PSRS. The network device can broadcast the first indication information, the second indication information, the third indication information, and the sixth indication information through the SIB. The specific content of the SIB may include the information in the following code, and the first indication information, the second indication information, the third indication information, and the sixth indication information can be sent through the extension bit in the DomainSysInfo-Group0 symbol in the SIB.

[0301] In the extended bits of the DomainSysInfo-Group0 symbol, PwrOffset_B can be the defined common channel power difference. PwrOffset_B = FTS / STS / BCH / CR-IND / GCI symbol power (i.e., the first power in the aforementioned embodiment) - DS symbol power, or PwrOffset_B = FTS / STS / BCH / CR-IND / GCI symbol power - maximum DS symbol power within one SIB period.

[0302] As an example, in the MIB, SIB, or GCI, an integer data (integer) can be used to represent the power difference between the first power and the second power, and the relative magnitude of the first power and the second power can be represented by the positive or negative sign of the integer data. For example, PwrOffset_B in the above code can be used as the first indication information, and the unit of the corresponding integer data is 0.5 decibel. When the terminal device receives the MIB sent by the first device, the integer data corresponding to PwrOffset_B in the above code can be multiplied by 0.5dB to obtain the power difference between the first power and the second power.

[0303] As an example, in the MIB, SIB or GCI, a finite number of integer data can be used to represent the number of PSRS symbols. For example, the PwrSwitchReserveSymNum field in the above code can be used as the third indication information to record the number of symbols N. At the same time, it can be configured in the network device or terminal device: PRSR cannot be used to transmit the demodulation reference signal (DMRS).

[0304] As an example, in MIB, SIB or GCI, a finite number of integer data can be used to represent the maximum modulation order of data when the PRSR symbol sends data. For example, the PwrSwitchReserveSymMaxModLevel field in the above code can be used as the second indication information to record the integer data corresponding to the maximum modulation order of data when the PSRS symbol sends data. Integer data 0 can be used to indicate that the maximum modulation order of data is QPSK when PSRS sends data; integer data 1 can be used to indicate that the maximum modulation order of data is 16QAM when PSRS sends data; integer data 2 can be used to indicate that the maximum modulation order of data is 64QAM when PSRS sends data; integer data 3 can be used to indicate that the maximum modulation order of data is 256QAM when PSRS sends data; integer data 4 can be used to indicate that the maximum modulation order of data is 1024QAM when PSRS sends data; integer data 5 can be used to indicate that the maximum modulation order of data is 4096QAM when PSRS sends data; integer data 7 can be used to indicate that data is not sent in PSRS symbols. At this time, data 7 is equivalent to the fifth indication information, and data 0-6 are equivalent to the second indication information. When the modulation order of the modulation and coding scheme (MCS) of the data carried by the scheduled DS is higher than PwrSwitchReserveSymMaxModLevel, the modulation order of the data sent in the PRSR symbol is limited to PwrSwitchReserveSymMaxModLevel.

[0305] As an example, PwrOffsetIndictMode in the above code can be used as the sixth indication information to indicate the relative size relationship among the first power, the second power, the third power and the fourth power.

[0306] At least one of the first indication information, the second indication information, the third indication information, and the fourth indication information may also be broadcast via DCI. For example, at least one of the first indication information, the second indication information, the third indication information, and the fourth indication information may be carried in DCI via a common PDCCH channel. Compared to DCI, MIB and SIB have more available bits for carrying the indication information that needs to be broadcast in this application.

[0307] After the network device sends the indication information to the terminal device, the terminal device sends capability reporting information of supporting reception of data or control signaling in the third symbol portion to the network device, indicating whether the terminal device supports reception of data or control signaling in the third symbol portion. Further, the capability reporting information may be used to indicate whether the terminal device supports reception of data or control signaling in the third symbol portion.

[0308] The network device receives capability reporting information sent by the terminal device indicating support for receiving data or control signaling in the third symbol portion. The terminal device may determine whether to send data or control signaling to the terminal device in the third symbol portion based on whether the network device supports receiving data or control signaling in the third symbol portion. Further, if the capability reporting information can be used to indicate whether receiving data or control signaling in the third symbol portion is supported, the network device may determine whether to send data or control signaling in the third symbol portion based on the capability reporting information.

[0309] If there are multiple terminal devices, some of which support receiving data or control signaling in the third symbol portion, while other terminal devices do not, the terminal devices that support receiving data or control signaling in the third symbol portion may send capability reporting information indicating support for receiving data or control signaling in the third symbol portion. In the communication system, when reporting capabilities, the T-node may indicate whether it supports receiving data using the PRSR symbol or whether it supports including the PSRS symbol in the radio frame.

[0310] Then, the terminal device can receive the first symbol, the third symbol and the second symbol sent in sequence by the first device.

[0311] As an example, the T-node reporting capability in the communication system may be implemented through the following code.

[0312] In the information reported by the T node, PwrSwitchReserveSymForData can be used to indicate whether the T node supports introducing data in PSRS symbols. If this field is yes (true), it means that the T node can receive data in PSRS symbols. If this field is no (false), it means that the T node cannot receive data in PSRS symbols.

[0313] Exemplarily, if the network device uses Null-GCI or PS-GCI as the symbol of the third symbol part, then the network device may not reserve symbols in the third symbol part for sending any of the above-mentioned indication information, the power difference between the first power and the third power, the number of symbols of at least one symbol included in the third symbol part, and the modulation order of the data carried by the symbols of the third symbol part for broadcasting or sending to the terminal device. The number of symbols included in the third symbol part can be carried by other symbols included in the symbols of the first symbol part. For example, when the symbols of the first symbol part include a control resource indicator, the total number of symbols of the management node control information can be recorded or carried in the control resource indicator. The total number of symbols of the management node control information recorded or carried in the control resource indicator can be the sum of the number of empty symbols of the management node control information and the number of non-empty symbols (Null-GCI) of the management node control information.

[0314] Exemplarily, if the network device uses the empty symbol of the management node control information as the symbol included in the third symbol part, the power difference between the first power and the second power can be configured or preset. For example, the power difference between the first power and the second power can be stored locally in the network device, and / or the power difference between the first power and the second power can be stored locally in the terminal device. Alternatively, the power difference between the first power and the second power can be stored in a third device, and the network device or the terminal device can obtain the power difference between the first power and the second power from the third device. Alternatively, the size relationship between the first power and the second power can be limited by a pre-set rule, thereby limiting the power difference between the first power and the second power to be greater than (or greater than or equal to) 0, or limiting the power of the first power and the second power to be less than (or less than or equal to) 0.

[0315] Exemplarily, the method provided in the embodiment of the present application is applicable to Bluetooth (BT) and SparkLink (or NearLink) communication. In the embodiment of the present application, Bluetooth and Bluetooth low energy (BLE) can refer to each other. NearLink and SparkLink low energy (SLE), SparkLink basic access (SLB), or SparkLink position (SLP) can also refer to each other.

[0316] Some embodiments of the solutions provided by this application are introduced below.

[0317] Example 1:

[0318] Bluetooth (BT) and SparkLink (or NearLink) can both form overlapping piconets, and both utilize the 2.4 GHz frequency band and frequency hopping technology. Their similarities allow for the reuse of some modules, saving chip cost, area, and power consumption. This allows for a high degree of chip resource reuse and rapid iteration across multiple chips.

[0319] BLE and SLE can share a set of radio frequency architectures and pathways. As shown in Figure 15, a schematic diagram of a chip architecture provided in an embodiment of the present application is shown. As shown in Figure 15, the design can achieve resource sharing of the central processing unit (CPU), radio frequency (RF) unit), analog baseband (ABB) unit, or modem, and reuse of some modules of the media access control (MAC) layer, thereby saving chip area, reducing chip cost and power consumption.

[0320] Figure 16 shows another chip architecture diagram provided by an embodiment of the present application. As shown in Figure 16, the MAC units of BT, SLE, and wireless fidelity (WIFI) are implemented independently, while the RF unit and Modem unit of each mode are all shared.

[0321] Figure 17 shows another chip architecture diagram provided by an embodiment of the present application. As shown in Figure 17, the MAC units of BT, SLE, and WIFI are independently implemented, and the modems of BT, SLE, and WIFI are also independently implemented, while the RF units of each mode are all shared.

[0322] Figure 18 shows another chip architecture diagram provided by an embodiment of the present application. As shown in Figure 18, the MAC units of BT, SLE, and WIFI are independently implemented, while some modes, such as BT and SLE, share a common modem. Other modes, such as WIFI, have their own independent modem implementations, while all RF units are shared.

[0323] Example 2:

[0324] SLE chips can be manufactured using 14 / 28 / 40nm processes and packaged in chip size packages (CSP), ball grid array (BGA), and quad flat no-lead (QFN), with either internal or external flash memory. Depending on the application scenario, at least one of the following subsystems, including a power management unit (PMU), clock management unit (CMU), active optical network (AON), wireless local area network (WLAN) or Bluetooth, SLE, global navigation satellite system (GNSS), application (APP), and audio, can be integrated onto a single chip, minimizing area, maximizing functionality, and improving performance and reliability.

[0325] The present application provides a chip design method in which the SLE and other subsystems are integrated on a single chip. The subsystems of the chip can be tailored and combined according to different products, and different subsystems are connected via a bus.

[0326] As shown in Figure 19, a schematic diagram of a chip module framework provided by an embodiment of the present application is shown. As shown in Figure 19, for products that require functional modules such as WIFI or GNSS and need to connect to Bluetooth and Star Flash devices, BT and SLE can be divided into different systems, and then combined with WIFI System, GNSS System, Always On System, PMU, CMU, Flash memory, etc. on a single chip. Different subsystems are connected through a bus.

[0327] Figure 20 shows another schematic diagram of a chip module framework provided by an embodiment of the present application. As shown in Figure 20, for devices that do not require functional modules such as Wi-Fi or GNSS but require audio functions, in order to save area and cost, BLE and SLE can be combined into one subsystem, which can then be combined with the App System, Audio System, Always On System, PMU, CMU, Flash, etc. on a single chip. Different subsystems are connected via a bus.

[0328] Figure 21 shows another schematic diagram of a chip module framework provided by an embodiment of the present application. As shown in Figure 21, for devices that do not require functional modules such as Wi-Fi or GNSS, nor audio functions, in order to save area and cost, BLE and SLE can be combined into one subsystem, which can then be combined with the Always On System, CMU, PMU, Flash, etc. on a single chip, with the different subsystems connected via a bus.

[0329] Example 3:

[0330] The WiFi 2.4G frequency band is 2412-2472MHz, while the BT / BLE / SLE frequency band is 2402-2480MHz, potentially interfering with each other. SLE and BT / BLE within the same core can be allocated service time slots through software scheduling, but SLE and BT / BLE / WiFi on different cores lack unified scheduling.

[0331] The embodiment of the present application provides a coexistence solution for SLE / BT / BLE / WIFI. Depending on whether SLE and BT / BLE / WIFI share the same antenna, the coexistence scenario is divided into different antenna coexistence (using different antennas) and shared antenna coexistence (using the same antenna), and different coexistence strategies are given.

[0332] For heterogeneous antenna coexistence, if SLE and BT / BLE coexist, the transmit and receive frequencies of SLE and BT / BLE can be kept different (i.e., frequency division multiplexing). The software can handle this based on the frequency hopping sequence (i.e., code division multiplexing), service cycle, and interval (i.e., time division multiplexing). If SLE and Wi-Fi coexist, if isolation cannot meet the requirements, it is necessary to avoid the WLAN channel (i.e., channel avoidance) to reduce the impact of WLAN. At the same time, a cluster scheduling mechanism can be added to aggregate and send Wi-Fi packets (i.e., cluster scheduling) to reduce the probability of WLAN interference.

[0333] For coexistence using the same antenna, either a software static strategy or a hardware packet traffic arbitration (PTA) strategy can be used. The advantages of the software static strategy include minimal hardware requirements, minimal software modifications, and no dynamic radio frequency (RF) switching (such as RF recovery). The advantages of the PTA strategy include faster service state switching and finer switching time granularity.

[0334] Taking the coexistence of SLE and Wi-Fi as an example, Figure 22 shows a schematic diagram of a software static policy framework provided by an embodiment of the present application. As can be seen from Figure 22, the software static policy may include: after SLE is started, the host (HOST) is configured through software to notify Wi-Fi to exit the current RF path. In this scenario, Wi-Fi can check the SLE startup flag, and the software can set it to switch from the current RF path to another RF path. The chip needs to support software-set switching.

[0335] Exemplarily, as shown in FIG23, a schematic diagram of the framework of a hardware arbitration time division (PTA) strategy provided in an embodiment of the present application is provided. As can be seen from FIG23, the hardware arbitration time division (PTA) strategy includes: any combination of transmission (TX) and reception (RX) of each party is time-divided, and the PTA module will transmit the occupancy status of the radio frequency channel to each party respectively, using different level signals to indicate that the radio frequency channel is occupied by SLE / BT / BLE / WIFI, and this signal is used to notify the software or hardware to perform the corresponding processing. Different services can also set different PTA priorities, and high-priority services can seize air interface resources.

[0336] Example 4:

[0337] The Star Flash standard defines asynchronous and synchronous data links. Asynchronous links are divided into asynchronous unicast and multicast, and synchronous links are divided into synchronous unicast, multicast, and broadcast. This embodiment of the application designs a set of SLE link selection schemes based on the different real-time data requirements of different products. By connecting different devices in different scenarios, different data links can be used to support the needs of different product application scenarios.

[0338] Figure 24 is a schematic diagram of a link establishment process provided by an embodiment of the present application. As shown in Figure 24, after the T node sends a broadcast packet to the G node, the G node sends a scan access request to the T node. Further, after the T node sends a scan access response to the G node, an asynchronous unicast link is established between the G node and the T node, and data is transmitted over the established asynchronous unicast link.

[0339] Figure 25 is a schematic diagram of another link establishment process provided by an embodiment of the present application. As shown in Figure 25, after the T node sends a broadcast packet to the G node, the G node sends a scan access request to the T node. Furthermore, after the T node sends a scan access response to the G node, an asynchronous multicast link is established between the G node and the T node, and data is transmitted over the established asynchronous multicast link.

[0340] For products (such as non-audio devices such as keyboards, mice, and styluses) or services that do not require real-time data (that is, the delay requirement of the product or service is greater than the first value), an asynchronous unicast link as shown in Figure 24 or an asynchronous multicast link as shown in Figure 25 can be established for data transmission.

[0341] Figure 26 is a schematic diagram of another link establishment process provided by an embodiment of the present application. As shown in Figure 26, after the T node sends a broadcast packet to the G node, the G node sends a scan access request to the T node. Furthermore, after the T node sends a scan access response to the G node, the G node and the T node first establish an asynchronous unicast link, and then establish a synchronous unicast link, and data is transmitted over the established synchronous unicast link.

[0342] Figure 27 is a schematic diagram of another link establishment process provided by an embodiment of the present application. As shown in Figure 27, after the T node sends a broadcast packet to the G node, the G node sends a scan access request to the T node. Furthermore, after the T node sends a scan access response to the G node, the G node and the T node first establish an asynchronous unicast link, then establish a synchronous multicast link, and transmit data over the established synchronous multicast link.

[0343] For products (such as audio devices such as headphones and microphones) or services with real-time data requirements (that is, the delay requirement of the product or service is less than the second value), as shown in Figure 26 or Figure 27, an asynchronous unicast link can be established first, and then a synchronous unicast link or a synchronous multicast link can be established for data transmission.

[0344] Figure 28 is a schematic diagram of another link establishment process provided by an embodiment of the present application. As shown in Figure 28, after the T node sends a broadcast packet to the G node, the G node sends a scan access request to the T node. Furthermore, after the T node sends a scan access response to the G node, an asynchronous unicast link is established between the G node and the T node, and data transmission is performed after synchronization is achieved by adding timestamps to the data packets.

[0345] Figure 29 is a schematic diagram of another link establishment process provided by an embodiment of the present application. As shown in Figure 29, after the T node sends a broadcast packet to the G node, the G node sends a scan access request to the T node. Furthermore, after the T node sends a scan access response to the G node, an asynchronous multicast link is established between the G node and the T node, and data transmission is performed after synchronization is achieved by adding timestamps to the data packets.

[0346] For products (such as audio devices such as headsets and live microphones) or services that have data real-time requirements but not particularly high real-time requirements (that is, the delay requirement of the product or service is less than the first value and greater than the second value), asynchronous unicast or asynchronous multicast links can also be established to achieve synchronization by adding timestamps to data packets.

[0347] Embodiment 5:

[0348] As shown in Figure 30, the StarFlash protocol defines four different radio frame types. Each frame format corresponds to different sensitivity, frame length, modulation mode, and synchronization sequence. Physical layer parameter negotiation can be used to select different frame formats in different scenarios to maximize performance benefits. The following examples provide examples of selecting different frame formats in different scenarios.

[0349] Figure 31 shows an example of a frame format application in a scenario provided by an embodiment of the present application. For low-latency products (such as keyboards, mice, styluses, toothbrushes, microphones, etc.) or business scenarios (i.e., products or services requiring a latency less than the first duration), frame format 1 is selected for broadcast access. After entering the connected state, frame format 2 is switched through physical layer parameter negotiation.

[0350] As shown in Figure 32, an example of frame format application in another scenario provided by an embodiment of the present application is shown. Among them, for products (such as mobile phones, headphone audio) or business scenarios that have both low latency (i.e., the latency requirement of the product or service is less than the first duration) and anti-interference demands (i.e., the anti-interference capability requirement of the product or service is greater than the set threshold), frame format 1 is selected for broadcast access, and after entering the connected state, it is switched to frame format 2 or frame format 3 through physical layer parameter negotiation.

[0351] As shown in Figure 33, an example of frame format application in another scenario provided by an embodiment of the present application is shown. For extremely low-cost devices that only support Gaussian frequency shift keying (GFSK) frame format (GFSK has a higher maximum transmit power than phase shift keying (PSK)), or devices that are sensitive to maximum transmit power (i.e., the maximum transmit power must be greater than a first power threshold), frame format 1 is selected for broadcast access, and no frame format switching is performed subsequently.

[0352] As shown in Figure 34, an example of frame format application in another scenario provided by an embodiment of the present application is shown. For the ultra-long-distance coverage scenario of the Internet of Things (IoT), frame format 4 is selected for broadcasting and connection. When the distance is shortened, frame format 2 or 3 can be switched through physical layer parameter negotiation. Otherwise, frame format 4 is maintained.

[0353] It should be noted that the frame format one in the embodiment of the present application can also be called the frame format corresponding to the Star Flash Wireless Frame Type 1, the frame format two in the embodiment of the present application can also be called the frame format corresponding to the Star Flash Wireless Frame Type 2, the frame format three in the embodiment of the present application can also be called the frame format corresponding to the Star Flash Wireless Frame Type 3, and the frame format four in the embodiment of the present application can also be called the frame format corresponding to the Star Flash Wireless Frame Type 4.
