Communication method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on June 30, 2023, with application number 202310809292.2 and application name “Communication Method and Device,” the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and more specifically, to a communication method and device. Background Art

[0003] Ultra-wideband (UWB) technology is a wireless carrier communication technology that transmits data by sending and receiving extremely narrow pulses in the nanosecond or microsecond range. UWB technology occupies a wide spectrum and has a low radiation spectral density, which gives it advantages such as strong multipath resolution, low power consumption, and strong confidentiality.

[0004] Typically, a UWB device (one that receives or transmits UWB signals) is in sleep mode and switches to active mode only when it needs to communicate. Therefore, it is crucial to ensure that a UWB device in sleep mode can switch to active mode.

[0005] Currently, the main method for waking up UWB devices is to transmit and receive wake-up sequences. However, this method is prone to waking up UWB devices by mistake. Therefore, how to effectively wake up UWB devices is a technical problem that needs to be solved urgently.

[0006] Summary of the Invention

[0007] The present application provides a communication method and apparatus that can effectively wake up a UWB device.

[0008] In a first aspect, a communication method is provided, which is applied to a UWB system, the method comprising: generating a first signal, the first signal being used to wake up a receiving device, the first signal being used to indicate N bits, the value of the pth bit in the N bits being determined by the high-low relationship between the average energy in a first pulse burst interval and the average energy in a second pulse burst interval, the first pulse burst interval being the previous pulse burst interval of the second pulse burst interval, N being a positive integer, and p being a positive integer less than or equal to N; and sending the first signal to the receiving device.

[0009] Specifically, the execution subject of the solution described in the first aspect can be a transmitting device, or a module or chip used to perform the functions of the transmitting device, etc., without limitation. The following description takes the transmitting device as an example. The transmitting device is a UWB device.

[0010] It should be noted that the average energy in the first pulse burst interval refers to the ratio of the sum of the energy in the first pulse burst interval to the interval length of the first pulse burst interval, and the average energy in the second pulse burst interval refers to the ratio of the sum of the energy in the second pulse burst interval to the interval length of the second pulse burst interval.

[0011] By adopting the high and low relationship between the average energy in two pulse burst intervals to transmit a bit of information, when the first signal is interfered with, the average energy in the two pulse burst intervals will be enhanced or weakened to the same or similar degree, but the high and low relationship between the average energy in the two pulse burst intervals will not be changed. This is conducive to the receiving device to correctly demodulate the first signal, and thus to effectively wake up the receiving device.

[0012] In a second aspect, a communication method is provided, which is applied to a UWB system, the method comprising: receiving a first signal, the first signal being used to wake up a receiving device, the first signal being used to indicate N bits, the value of the pth bit in the N bits being determined by the high and low relationship between the average energy in a first pulse burst interval and the average energy in a second pulse burst interval, the first pulse burst interval being the previous pulse burst interval of the second pulse burst interval, N being a positive integer, and p being a positive integer less than or equal to N; waking up the receiving device according to the first signal.

[0013] Specifically, the execution subject of the solution described in the second aspect can be a receiving device, or a module or chip used to perform the functions of the receiving device, etc., without limitation. The following description takes the receiving device as an example. The receiving device is a UWB device.

[0014] By adopting the high and low relationship between the average energy in two pulse burst intervals to transmit a bit of information, when the first signal is interfered with, the average energy in the two pulse burst intervals will be enhanced or weakened to the same or similar degree, but the high and low relationship between the average energy in the two pulse burst intervals will not be changed. The receiving device can correctly demodulate the first signal and thus effectively wake up the receiving device.

[0015] In combination with any one of the first and second aspects, the first pulse burst interval and the second pulse burst interval are located in the same time unit.

[0016] In this way, the receiving device can obtain one bit of information within the same time unit.

[0017] In combination with any one of the first and second aspects, the first pulse burst interval is adjacent to the second pulse burst interval.

[0018] It should be noted that the present application supports that there is energy in only one pulse burst interval in a time unit, that is, the transmitting device only transmits pulses in one pulse burst interval in a time unit.

[0019] In this way, the receiving device can obtain one bit of information as quickly as possible.

[0020] In combination with any one of the first and second aspects, the first pulse burst interval is located in a first time unit, the second pulse burst interval is located in a second time unit, and the first time unit is a previous time unit of the second time unit.

[0021] By adopting two time units to transmit one bit of information, it is beneficial to improve the resistance of signal 1 to channel interference.

[0022] In combination with any one of the first and second aspects, the first time unit is adjacent to the second time unit.

[0023] In this way, the receiving device can obtain one bit of information as quickly as possible.

[0025] It can be understood that when the average energy in the first pulse burst interval is higher than the average energy in the second pulse burst interval, the value of the p-th bit may be bit 0.

[0026] In this way, one bit of information can be transmitted.

[0027] In combination with any one of the first and second aspects, the first pulse burst interval includes M pulses, and the pulse repetition frequency of the transmitted M pulses is an integer multiple of 62.4 MHz.

[0028] This allows compatibility with existing standards.

[0029] In combination with any one of the first and second aspects, the average energy in the first pulse burst interval is lower than the average energy in the second pulse burst interval, and the value of the p-th bit is bit 0.

[0030] It can be understood that when the average energy in the first pulse burst interval is lower than the average energy in the second pulse burst interval, the value of the p-th bit can be bit 1.

[0031] In this way, one bit of information can be transmitted.

[0032] In combination with any one of the first and second aspects, the second pulse burst interval includes W pulses, and the pulse repetition frequency of the W pulses is an integer multiple of 62.4 MHz.

[0033] This allows compatibility with existing standards.

[0034] In combination with any one of the first and second aspects, the time length of the first pulse burst interval is equal to the time length of the second pulse burst interval.

[0035] For example, the duration of the first pulse burst interval and the duration of the second pulse burst interval are both 4 microseconds, which is consistent with half the duration of the pulse burst interval specified in existing standards.

[0036] In a third aspect, a communication device is provided. The communication device may be a sending device, or a device or module for executing the functions of the sending device.

[0037] In one possible implementation, the communication device may include a module or unit corresponding to each of the methods / operations / steps / actions described in the first aspect. The module or unit may be a hardware circuit, software, or a combination of hardware circuit and software.

[0067] First, a communication system to which the embodiments of the present application are applicable is described.

[0068] Figure 1 is a schematic diagram of a communication system 100 applicable to an embodiment of the present application. As shown in Figure 1, the communication system 100 includes: a transmitting device 110 and a receiving device 120. The transmitting device 110 refers to a device that transmits UWB signals, and the receiving device 120 refers to a device that receives UWB signals. The transmitting device 110 and the receiving device 120 communicate using UWB technology. The transmitting device 110 and the receiving device 120 both include a UWB signal processing module. For example, the transmitting device 110 includes a UWB signal transmitting module (Tx UWB). The receiving device 120 includes a UWB signal receiving module (Rx UWB). In addition, the transmitting device 110 and the receiving device 120 can both be referred to as UWB devices. For ease of description, the following description takes the transmitting device 110 and the receiving device 120 as an example.

[0069] It should be noted that FIG1 only illustrates the communication system 100 including one transmitting device 110 and one receiving device 120 as an example, but the communication system 100 is not limited to including more other devices, for example, it may also include more receiving devices 120.

[0070] Specifically, the sending device 110 may be a network device, and the receiving device 120 may be a terminal device; or the sending device 110 may be a terminal device, and the receiving device 120 may be a network device. A description of the network device and the terminal device can be found below.

[0071] A terminal device is a device with wireless transceiver capabilities and can refer to user equipment (UE), access terminal, subscriber unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent or user device. The terminal device may also be a satellite phone, a cellular phone, a smart phone, a wireless data card, a wireless modem, a machine type communication device, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a customer premises equipment (CPE), a smart point of sale (POS) machine, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a communication device carried on a high-altitude aircraft, a wearable device, a drone, a robot, a terminal in device-to-device (D2D) communication, a terminal in vehicle-to-everything (V2X), a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a smart grid, etc. This application does not limit the wireless terminals in the wireless grid, transportation safety, smart city, smart home, or terminal devices in the communication network evolved after 5G.

[0072] The communication device used to implement the functions of the terminal device can be the terminal device, or it can be a device that can support the terminal device to implement the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In this application, the chip system can be composed of a chip or include a chip and other discrete devices.

[0073] The above-mentioned network device is a device with wireless transceiver functions, which is used to communicate with terminal devices. The network device can be a node in the radio access network (RAN), which can be called a base station or a RAN node. It can be an evolved Node B (eNB or eNodeB) of long term evolution (LTE); or a base station of a 5G network such as gNodeB (gNB) or a base station in a public land mobile network (PLMN) evolved after 5G, a broadband network gateway (BNG), an aggregation switch or a third generation partnership project (3GPP) access device, etc.

[0074] The RAN can be configured as a RAN defined by the 3GPP protocol, an open radio access network (O-RAN), or a cloud radio access network (C-RAN). The network device 110 can also include various forms of base stations, such as macro base stations, micro base stations (also known as small stations), relay stations, transmission points (transmitting and receiving points, TRP), transmission points (transmitting points, TP), mobile switching centers, and devices that perform base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, network devices in non-terrestrial networks (NTN), etc., without specific limitation.

[0075] The network equipment may also include network elements or modules that implement some functions of the base station, for example, one or more of the following: a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). Optionally, the CU can be further separated into a CU-control plane (CP) and a CU-user plane (UP). The functions of the CU and DU can be implemented by different network elements, or simultaneously by the baseband unit (BBU) of the base station. The functions of the RU can be implemented by the radio frequency equipment of the base station. For example, the radio frequency equipment of the base station may be a remote radio unit (RRU), a pico remote radio unit (pRRU), an active antenna unit (AAU), or other units, modules or devices with radio frequency processing functions.

[0079] In addition, the communication system 100 may also include a star topology or a point-to-point topology. The star topology involves data communication between a central control node and one or more other devices, which is also applicable to communication between different devices in the point-to-point topology.

[0080] As can be seen from the background technology, the current method of waking up UWB devices by transmitting and receiving wake-up sequences is prone to false awakening of UWB devices. Specifically, the wake-up pulse beam (WUB) used to wake up UWB devices is generated based on on-off keying (OOK) modulation, that is, one bit of information is transmitted by the presence or absence of energy. When the transmitting device sends bit 0 (i.e., no energy) to the receiving device, the receiving device may receive bit 1 due to channel interference and other influences, which may cause the receiving device to be falsely awakened. Therefore, how to effectively wake up UWB devices is a technical problem that needs to be solved urgently.

[0081] In view of this, the present application provides a communication method and apparatus that can effectively wake up a UWB device.

[0082] The communication method according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0083] FIG2 is a schematic diagram of the interaction flow of a communication method 200 according to an embodiment of the present application. The method flow in FIG2 can be executed by the transmitting device 110 and the receiving device 120, or by modules and / or devices (e.g., chips or integrated circuits) with corresponding functions installed in the transmitting device 110 and the receiving device 120, without limitation. The following description will be made using the transmitting device 110 and the receiving device 120 as an example. As shown in FIG2 , the method 200 includes:

[0084] S210 , the sending device 110 generates a signal 1 (such as a first signal), where the signal 1 is used to wake up the receiving device 120 .

[0085] Specifically, signal 1 is used to indicate N bits, and the value of each bit is determined by the relationship between the average energy levels within two pulse burst intervals. For example, the value of the pth bit among N bits is determined by the relationship between the average energy levels within pulse burst interval 1 (e.g., the first pulse burst interval) and the average energy levels within pulse burst interval 2 (e.g., the second pulse burst interval), where pulse burst interval 1 is the pulse burst interval immediately preceding pulse burst interval 2. N is a positive integer greater than 1, and p is a positive integer less than or equal to N.

[0086] It should be noted that the average energy within the pulse burst interval 1 refers to the ratio between the sum of the energy within the pulse burst interval 1 and the interval length (or time length) of the pulse burst interval 1, and the average energy within the pulse burst interval 2 refers to the ratio between the sum of the energy within the pulse burst interval 2 and the interval length (or time length) of the pulse burst interval 2.

[0087] The value of the p-th bit is determined by the relationship between the average energy in the pulse burst interval 1 and the average energy in the pulse burst interval 2, which can be seen in the following description.

[0088] In one example, the average energy in pulse burst interval 1 is higher than the average energy in pulse burst interval 2, and the value of the p-th bit is bit 1. In this way, one bit of information can be transmitted.

[0089] In one example, the average energy in pulse burst interval 1 is lower than the average energy in pulse burst interval 2, and the value of the p-th bit is bit 1. In this way, one bit of information can be transmitted.

[0090] In one example, the average energy in the pulse burst interval 1 is higher than the average energy in the pulse burst interval 2, and the value of the p-th bit is bit 0. In this way, one bit of information can be transmitted.

[0091] In one example, the average energy in the pulse burst interval 1 is lower than the average energy in the pulse burst interval 2, and the value of the p-th bit is bit 0. In this way, one bit of information can be transmitted.

[0092] When the average energy within pulse burst interval 1 is higher than the average energy within pulse burst interval 2, it can indicate that pulse burst interval 1 includes M (a positive integer) pulses, and the pulse repetition frequency of the transmitted M pulses is an integer multiple of 62.4 MHz, which is compatible with existing standards. When the average energy within pulse burst interval 2 is higher than the average energy within pulse burst interval 1, it can indicate that pulse burst interval 2 includes W (a positive integer) pulses, and the pulse repetition frequency of the transmitted W pulses is an integer multiple of 62.4 MHz, which is compatible with existing standards.

[0093] When the average energy in pulse burst interval 1 is higher than the average energy in pulse burst interval 2, this application does not limit whether the average energy in pulse burst interval 2 is 0. When the average energy in pulse burst interval 2 is higher than the average energy in pulse burst interval 1, this application does not limit whether the average energy in pulse burst interval 1 is 0.

[0094] In summary, transmitting one bit of information by comparing the high and low relationship between the average energies within two pulse burst intervals helps reduce the probability of falsely waking up the UWB device.

[0095] S220 , the sending device 110 sends signal 1 to the receiving device 1120 .

[0096] Accordingly, the receiving device 120 receives the signal 1 .

[0097] S230 : The receiving device 120 wakes up the receiving device 120 according to the signal 1 .

[0098] Specifically, the receiving device 120 can determine the value of each bit based on the high and low relationship between the average energy in the two pulse burst intervals, and then obtain N bits, and determine whether to wake up the receiving device 120 based on the N bits.

[0099] In summary, by using the high and low relationship between the average energy in two pulse burst intervals to transmit one bit of information, when signal 1 is interfered with, the average energy in the two pulse burst intervals will be enhanced or weakened to the same or similar degree, but the high and low relationship between the average energy in the two pulse burst intervals will not be changed, which is conducive to the receiving device to correctly demodulate signal 1, and thus can effectively wake up the receiving device.

[0100] It should be noted that the aforementioned N bits may include identification information of the receiving device 120. That is, the receiving device 120 may determine whether the identification information included in the N bits matches the identification of the receiving device. If so, the receiving device 120 may be woken up; if not, the receiving device 120 may not be woken up.

[0101] In addition, the N bits may also include synchronization information, which is used to trigger the receiving device 120 to start receiving signal 1. When the N bits include bits for indicating synchronization information and bits for indicating identification information, the bits for indicating synchronization information precede the bits for indicating identification information.

[0102] It should also be noted that for the specific description of signal 1, please refer to the existing standards and will not be repeated here.

[0103] The relationship between the pulse burst interval 1 and the pulse burst interval 2 is described below with reference to FIG. 3 and FIG. 4 .

[0104] FIG3 is a schematic diagram of the relationship between the pulse burst interval 1 and the pulse burst interval 2 of an embodiment of the present application. As shown in FIG3 , the pulse burst interval 1 and the pulse burst interval 2 are located in the same time unit. A time unit may be one millisecond, or multiple milliseconds, etc., without limitation. As shown in FIG3 (a), if there is energy in the pulse burst interval 1 and no energy in the pulse burst interval 2, it represents bit 1, which can complete the transmission of one bit of information. As shown in FIG3 (b), if there is no energy in the pulse burst interval 1 and there is energy in the pulse burst interval 2, it represents bit 0, which can complete the transmission of one bit of information.

[0105] Specifically, when pulse burst interval 1 and pulse burst interval 2 are within the same time unit, the receiving device can obtain one bit of information within the same time unit. When pulse burst interval 1 and pulse burst interval 2 are adjacent pulse burst intervals, the receiving device can obtain one bit of information as quickly as possible.

[0106] In the content shown in Figure 3, the embodiment of the present application is described by taking pulse burst interval 1 and pulse burst interval 2 as two adjacent pulse burst intervals as an example, but is not limited to the scenario where there is at least one other pulse burst interval between pulse burst interval 1 and pulse burst interval 2.

[0107] FIG4 is another schematic diagram of the relationship between pulse burst interval 1 and pulse burst interval 2 in an embodiment of the present application. As shown in FIG4 , pulse burst interval 1 is located in time unit 1, and pulse burst interval 2 is located in time unit 2. As shown in FIG4 (a), if there is energy in pulse burst interval 1 and no energy in pulse burst interval 2, it represents bit 1, which can complete the transmission of one bit of information. As shown in FIG4 (b), if there is no energy in pulse burst interval 1 and energy in pulse burst interval 2, it represents bit 0, which can complete the transmission of one bit of information.

[0108] When pulse burst interval 1 and pulse burst interval 2 are located in two different time units, that is, two time units are used to transmit one bit of information, this helps improve the resistance of signal 1 to channel interference. Specifically, when time unit 1 and time unit 2 are two adjacent time units, the receiving device can obtain the one bit of information as quickly as possible.

[0109] In the content shown in Figure 4, the embodiment of the present application is described by taking time unit 1 and time 2 as two adjacent time units as an example, but is not limited to the application scenario where there is at least one other time unit between time unit 1 and time unit 2.

[0110] It should be noted that when pulse burst interval 1 and pulse burst interval 2 are located in time unit 1 and time unit 2 respectively, time unit 1 and time unit 2 can each include other pulse burst intervals, that is, time unit 1 can include at least two pulse burst intervals, and time unit 2 can include at least two pulse burst intervals, and this is not limited.

[0111] In the above description, the duration of pulse burst interval 1 and the duration of pulse burst interval 2 can be the same or different, and this is not limited to this. For example, the duration of pulse burst interval 1 and the duration of pulse burst interval 2 can both be 4 microseconds. This is consistent with half the duration of a pulse burst interval specified in existing standards.

[0112] It should be noted that this application supports that only one pulse burst interval in a time unit has energy, that is, the transmitting device transmits a pulse in a pulse burst interval in a time unit. It should be noted that the contents shown in Figures 3 and 4 are only understood as examples and are not intended to be final limitations.

[0113] Finally, the device embodiment of the embodiment of the present application is introduced.
