Description

[0001] This application is a divisional application. The application number of the original application is 202310809292.2, and the original application date is June 30, 2023. The entire contents of the original application are incorporated into this application by reference. 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 of nanoseconds or microseconds. UWB technology occupies a wide spectrum range and has a low radiation spectrum density, which makes it have the advantages of strong multipath resolution, low power consumption and strong confidentiality.

[0004] Usually, a UWB device (a device that receives or sends UWB signals) is in sleep mode, and only when the UWB communication mode is needed will the UWB device switch from sleep mode to working mode. Therefore, it is particularly important to enable a UWB device in sleep mode to switch to working mode.

[0005] Currently, the method of waking up UWB devices mainly adopts the method of transmitting and receiving wake-up sequences, but this method easily leads to the false awakening of UWB devices. Therefore, how to effectively wake up UWB devices is a technical problem that needs to be solved urgently. Summary of the invention

[0006] The present application provides a communication method and apparatus that can effectively wake up a UWB device.

[0007] 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 among the N bits being determined by the high-low relationship between average energy in a first pulse burst interval and 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; sending the first signal to the receiving device.

[0008] Specifically, the execution subject of the solution described in the first aspect may be a sending device, or a module or chip used to execute the function of the sending device, etc., which is not limited. The following description takes the sending device as an example. The sending device is a UWB device.

[0009] 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.

[0010] 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 extent, 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 then effectively wake up the receiving device.

[0011] 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 among 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; waking up the receiving device according to the first signal.

[0012] Specifically, the execution subject of the solution described in the second aspect may be a receiving device, or a module or chip used to execute the function of the receiving device, etc., which is not limited. The following description takes the receiving device as an example. The receiving device is a UWB device.

[0013] By using 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 extent, 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 effectively wake up the receiving device.

[0014] In combination with any one of the first aspect and the second aspect, the first pulse burst interval and the second pulse burst interval are located in the same time unit.

[0015] In this way, the receiving device can obtain one bit of information within the same time unit.

[0016] In combination with any one of the first and second aspects, the first pulse burst interval is adjacent to the second pulse burst interval.

[0017] 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 transmits a pulse only in one pulse burst interval in a time unit.

[0018] In this way, the receiving device can obtain one bit of information as quickly as possible.

[0019] In combination with any one of the first aspect and the second aspect, 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.

[0020] By using two time units to transmit one bit of information, this helps to improve the resistance of signal 1 to channel interference.

[0025] In this way, one bit of information can be transmitted.

[0026] In combination with any one of the first and second aspects, the first pulse burst interval includes M pulses, and a pulse repetition frequency of the transmitted M pulses is an integer multiple of 62.4 MHz.

[0027] This allows compatibility with existing standards.

[0028] 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.

[0029] 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.

[0030] In this way, one bit of information can be transmitted.

[0031] In combination with any one of the first aspect and the second aspect, 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.

[0032] This allows compatibility with existing standards.

[0033] In combination with any one of the first aspect and the second aspect, the time length of the first pulse burst interval is equal to the time length of the second pulse burst interval.

[0034] For example, the time length of the first pulse burst interval and the time length of the second pulse burst interval are both 4 microseconds, which can be consistent with half the time length of the pulse burst interval specified in the existing standard.

[0035] According to a third aspect, a communication device is provided. The communication device may be a sending device, or may be a device or module for executing the function of the sending device.

[0036] 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 a hardware circuit and software.

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 is taken as an example of the transmitting device 110 and the receiving device 120.

[0068] It should be noted that Figure 1The communication system 100 includes only one transmitting device 110 and one receiving device 120 as an example for description, but the communication system 100 is not limited to including more other devices, for example, it may also include more receiving devices 120 .

[0069] 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. For a description of the network device and the terminal device, please refer to the following.

[0070] A terminal device is a device with wireless transceiver functions, which 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 function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a communication device carried on a high-altitude aircraft, a wearable device, a drone, a robot, a terminal in device-to-device communication (D2D), 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, a smart grid (smart grid), etc. This application does not limit the wireless terminals in the wireless grid, the wireless terminals in transportation safety, the wireless terminals in the smart city, the wireless terminals in the smart home, or the terminal devices in the communication network evolved after 5G, etc.

[0071] The communication device for realizing the function of the terminal device can be a terminal device, or a device that can support the terminal device to realize the function, such as a chip system. The device can be installed in the terminal device or used in combination with the terminal device. In the present application, the chip system can be composed of a chip, or it can include a chip and other discrete devices.

[0072] The above-mentioned network equipment is a device with wireless transceiver function, which is used to communicate with the terminal equipment. The network equipment 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 base station (evolved NodeB, 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 service gateway (BNG), an aggregation switch or a third generation partnership project (3GPP) access device, etc.

[0073] The above-mentioned 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), etc. The network device 110 can also include various forms of base stations, such as: macro base stations, micro base stations (also called small stations), relay stations, transmission points (transmitting and receiving points, TRP), transmission points (transmitting points, TP), mobile switching centers, and devices that assume the function of base stations in device-to-device (D2D), vehicle-to-everything (V2X), machine-to-machine (M2M) communications, network devices in non-terrestrial networks (NTN), etc., without specific limitation.

[0074] The network device 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 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.

[0079] It can be seen from the content of the background technology that 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 the on-off keying (OOK) modulation method, that is, a 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 woken up by mistake. Therefore, how to effectively wake up UWB devices is a technical problem that needs to be solved urgently.

[0080] In view of this, the present application provides a communication method and apparatus, which can effectively wake up a UWB device.

[0081] The communication method of the embodiment of the present application is described below with reference to the accompanying drawings.

[0082] Figure 2 It is a schematic diagram of the interaction flow of the communication method 200 according to an embodiment of the present application. Figure 2 The method flow in the embodiment can be executed by the sending device 110 and the receiving device 120, or by a module and / or device (for example, a chip or an integrated circuit, etc.) with corresponding functions installed in the sending device 110 and the receiving device 120, without limitation. The sending device 110 and the receiving device 120 are used as an example for description. Figure 2 As shown, the method 200 includes:

[0083] 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 .

[0084] Specifically, signal 1 is used to indicate N bits, and the value of each bit is determined by the high-low relationship between the average energies in two pulse burst intervals. For example, the value of the p-th bit in N bits is determined by the high-low relationship between the average energy in pulse burst interval 1 (such as the first pulse burst interval) and the average energy in pulse burst interval 2 (such as the second pulse burst interval), and pulse burst interval 1 is the previous pulse burst interval of pulse burst interval 2. Wherein, N is a positive integer greater than 1, and p is a positive integer less than or equal to N.

[0085] It should be noted that the average energy within the pulse burst interval 1 refers to the ratio of the sum of the energy within the pulse burst interval 1 to 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 of the sum of the energy within the pulse burst interval 2 to the interval length (or time length) of the pulse burst interval 2.

[0086] 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, as described below.

[0087] 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 pth bit is bit 1. In this way, one bit of information can be transmitted.

[0088] 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 pth bit is bit 1. In this way, the transmission of one bit of information can be achieved.

[0089] 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 pth bit is bit 0. In this way, the transmission of one bit of information can be achieved.

[0090] 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 pth bit is bit 0. In this way, the transmission of one bit of information can be achieved.

[0091] When the average energy in pulse burst interval 1 is higher than the average energy in pulse burst interval 2, it can be represented that: pulse burst interval 1 includes M (a positive integer) pulses, and the pulse repetition frequency of the transmission of M pulses is an integer multiple of 62.4 MHz, which can be compatible with the existing standards. When the average energy in pulse burst interval 2 is higher than the average energy in pulse burst interval 1, it can be represented that: pulse burst interval 2 includes W (a positive integer) pulses, and the pulse repetition frequency of the transmission of W pulses is an integer multiple of 62.4 MHz, which can be compatible with the existing standards.

[0092] When the average energy in pulse burst interval 1 is higher than the average energy in pulse burst interval 2, the present 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, the present application does not limit whether the average energy in pulse burst interval 1 is 0.

[0093] In summary, transmitting one bit of information by the high-low relationship between the average energies in two pulse burst intervals is beneficial to reducing the probability of falsely waking up the UWB device.

[0094] S220 , the sending device 110 sends a signal 1 to the receiving device 1120 .

[0095] Accordingly, the receiving device 120 receives the signal 1 .

[0096] S230 , the receiving device 120 wakes up the receiving device 120 according to the signal 1 .

[0097] Specifically, the receiving device 120 can determine the value of each bit according to 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 according to the N bits.

[0098] 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.

[0099] It should be noted that the above-mentioned 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, and if so, determine to wake up the receiving device 120, and if not, do not wake up the receiving device 120.

[0100] In addition, the N bits may also include synchronization information (synchronization), which is used to trigger the receiving device 120 to start receiving signal 1. When the N bits include a bit for indicating synchronization information and a bit for indicating identification information, the bit for indicating synchronization information is before the bit for indicating identification information.

[0101] 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.

[0102] Combined with the following Figure 3 and Figure 4 The relationship between the pulse burst interval 1 and the pulse burst interval 2 is described.

[0103] Figure 3 Schematic diagram of a relationship between the pulse burst interval 1 and the pulse burst interval 2 in the embodiment of the present application. Figure 3 As shown, the pulse burst interval 1 and the pulse burst interval 2 are located in the same time unit. Wherein, a time unit can be one millisecond, or multiple milliseconds, etc., without limitation. Figure 3 As shown in (a), there is energy in pulse burst interval 1 and no energy in pulse burst interval 2, which indicates bit 1, which can complete the transmission of one bit of information. Figure 3 As shown in (b), there is no energy in the pulse burst interval 1, and there is energy in the pulse burst interval 2, which represents bit 0, which can complete the transmission of one bit of information.

[0104] Specifically, when pulse burst interval 1 and pulse burst interval 2 are in the same time unit, the receiving device can obtain one bit of information in the same time unit. When pulse burst interval 1 and pulse burst interval 2 are two adjacent pulse burst intervals, the receiving device can obtain one bit of information as quickly as possible.

[0105] Figure 3 In the content shown, 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.

[0106] Figure 4 FIG. 2 is another schematic diagram of the relationship between the pulse burst interval 1 and the pulse burst interval 2 in the embodiment of the present application. Figure 4 As shown, pulse burst interval 1 is located in time unit 1, and pulse burst interval 2 is located in time unit 2. Figure 4 As shown in (a), there is energy in pulse burst interval 1 and no energy in pulse burst interval 2, which indicates bit 1, which can complete the transmission of one bit of information. Figure 4 As shown in (b), there is no energy in the pulse burst interval 1, and there is energy in the pulse burst interval 2, which represents bit 0, which can complete the transmission of one bit of information.

[0107] When the pulse burst interval 1 and the 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 is conducive to improving the resistance of signal 1 to channel interference. Among them, when the time unit 1 and the time unit 2 are two adjacent time units, the receiving device can obtain one bit of information as quickly as possible.

[0108] Figure 4 In the content shown, 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.

[0109] It should be noted that when pulse burst interval 1 and pulse burst interval 2 are respectively located in time unit 1 and time unit 2, time unit 1 and time unit 2 may each include other pulse burst intervals, that is, time unit 1 may include at least two pulse burst intervals, and time unit 2 may include at least two pulse burst intervals, and this is not limited.

[0110] In the above description, the time length of the pulse burst interval 1 and the time length of the pulse burst interval 2 may be the same or different, and there is no limitation on this. For example, the time length of the pulse burst interval 1 and the time length of the pulse burst interval 2 may both be 4 microseconds. In this way, it can be consistent with the half time length of the pulse burst interval specified in the existing standard.

[0111] It should be noted that this application supports that there is energy in only one pulse burst interval in a time unit, that is, the sending device transmits a pulse in a pulse burst interval in a time unit. Figure 3 and Figure 4 The content shown is to be understood as an example only and not as a final limitation.
