Description

Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a communication method and device. Background Art

[0002] In the field of communications, data transmission between network devices and terminal devices is greatly affected by channel quality. For example, when a network device sends downlink data to a terminal device, if the channel quality corresponding to the frequency used to transmit the downlink data is poor, the terminal device may not be able to receive the downlink data, which may affect the normal communication between the terminal device and the network device. Therefore, how to effectively reduce the impact of channel quality on data transmission is a technical problem that needs to be solved urgently. Summary of the invention

[0003] The present application provides a communication method and device, which can effectively reduce the impact of channel quality on data transmission.

[0004] In a first aspect, a communication method is provided, including: determining information to be transmitted; sending the information to be transmitted to a receiving device within N time periods, wherein the first information transmitted within the i-th time period of the N time periods is associated with a first frequency, and the second information transmitted within the p-th time period of the N time periods is associated with a second frequency, N is a positive integer greater than 1, i and p are both positive integers less than or equal to N, i is not equal to p; the first frequency is different from the second frequency. The information to be transmitted includes the first information and the second information.

[0005] The execution subject of the solution described in the first aspect is a sending device, or a module or chip used to execute the function of the sending device, etc., which is not limited to this. For the convenience of description, the following description takes the sending device as an example.

[0006] It should be noted that the first information and the second information may be the same information or different information, and this is not limited.

[0007] By using different frequencies to transmit information, the frequency diversity gain of signal transmission can be improved, avoiding the situation where the entire information is lost due to poor channel quality corresponding to a certain frequency, thereby effectively reducing the impact of channel quality on data transmission.

[0008] In a possible implementation, the first frequency is determined based on a first mapping rule and the first information, and the first mapping rule is used to indicate the association between the first information and the first frequency; the second frequency is determined based on a second mapping rule and the second information, and the second mapping rule is used to indicate the association between the second information and the second frequency; wherein the first mapping rule is different from the second mapping rule.

[0009] Specifically, since the first mapping rule is different from the second mapping rule, the frequency associated with the information can be randomized to avoid repeated use of the same frequency, thereby obtaining a greater frequency diversity gain, and effectively reducing the impact of channel quality on data transmission.

[0010] A possible implementation method is to send information to be transmitted to a receiving device within N time periods, including: mapping first information to a first frequency to obtain a first signal, and mapping second information to a second frequency to obtain a second signal; sending the first signal to the receiving device within the i-th time period, and sending the second signal to the receiving device within the p-th time period.

[0011] Specifically, since the first frequency is different from the second frequency, the frequencies mapped to information in different time periods can be different, avoiding the same frequency from being reused, thereby obtaining a greater frequency diversity gain, and effectively reducing the impact of channel quality on data transmission.

[0012] A possible implementation method is to map the first information to the first frequency to obtain the first signal, including: activating the first frequency according to the first mapping rule and the first information to obtain the first signal; and mapping the second information to the second frequency to obtain the second signal, including: activating the second frequency according to the second mapping rule and the second information to obtain the second signal.

[0013] In this way, the present application supports the sending device to generate a signal for transmission through frequency shift keying modulation.

[0014] A possible implementation method is to map the first information to a first frequency to obtain a first signal, including: determining the first frequency according to a first mapping rule and the first information; performing on-off keying modulation on the first information at the first frequency to obtain the first signal; and mapping the second information to a second frequency to obtain a second signal, including: determining the second frequency according to a second mapping rule and the second information; performing on-off keying modulation on the second information at the second frequency to obtain the second signal.

[0015] In this way, the present application supports a transmitting device to generate a signal for transmission through on-off keying modulation.

[0016] In a possible implementation, the method further includes: sending configuration information to a receiving device, where the configuration information is used to configure transmission parameters of the information to be transmitted, and the configuration information includes at least one of the following: number of transmissions, modulation mode, modulation order, or time interval.

[0017] In this way, the receiving device can better receive the information to be transmitted.

[0018] In a possible implementation manner, the method further includes: sending a mapping rule corresponding to each time period in the N time periods to a receiving device.

[0019] In this way, the receiving device can obtain the mapping rules corresponding to each time period, and thus can better obtain the information to be transmitted.

[0020] In a second aspect, a communication method is provided, including: receiving information to be transmitted sent by a sending device within N time periods, first information transmitted within the i-th time period among the N time periods is associated with a first frequency, second information transmitted within the p-th time period among the N time periods is associated with a second frequency, N is a positive integer greater than 1, i and p are both positive integers less than or equal to N, i is not equal to p, the information to be transmitted includes first information and second information, and the first frequency is different from the second frequency; and processing the information to be transmitted.

[0021] The execution subject of the solution described in the second aspect is a receiving device, or a module or chip used to execute the function of the receiving device, etc., which is not limited. For the convenience of description, the following description is taken as an example of a receiving device.

[0022] It should be noted that the first information and the second information may be the same information or different information, and this is not limited.

[0023] By using different frequencies to transmit information, the frequency diversity gain of signal transmission can be improved, avoiding the situation where the entire information is lost due to poor channel quality corresponding to a certain frequency, thereby effectively reducing the impact of channel quality on data transmission.

[0024] In a possible implementation, the first frequency is determined by the transmitting device based on a first mapping rule and the first information, and the first mapping rule is used to indicate the association between the first information and the first frequency; the second frequency is determined by the transmitting device based on a second mapping rule and the second information, and the second mapping rule is used to indicate the association between the second information and the second frequency. The first mapping rule is different from the second mapping rule.

[0025] A possible implementation method is to receive information to be transmitted sent by a sending device within N time periods, including: within the i-th time period, receiving a first signal sent by the sending device, the first signal being a signal obtained by the sending device mapping the first information to a first frequency; and within the p-th time period, receiving a second signal sent by the sending device, the second signal being a signal obtained by the sending device mapping the second information to a second frequency.

[0026] In one possible implementation, the first signal is a signal obtained by the sending device determining the first frequency according to the first mapping rule and the first information, and activating the first frequency; and the second signal is a signal obtained by the sending device determining the second frequency according to the second mapping rule and the second information, and activating the second frequency.

[0027] In one possible implementation, the first signal is a signal obtained by the sending device determining the first frequency according to the first mapping rule and the first information, and performing on-off keying modulation on the first information at the first frequency; and the second signal is a signal obtained by the sending device determining the second frequency according to the second mapping rule and the second information, and performing on-off keying modulation on the second information at the second frequency.

[0028] In a possible implementation, the method further includes: receiving configuration information sent by a sending device, the configuration information being used to configure transmission parameters of the information to be transmitted, the configuration information including at least one of the following: number of transmissions, modulation mode, modulation order, or time interval.

[0029] In a possible implementation manner, the method further includes: receiving a mapping rule corresponding to each time period in the N time periods sent by the sending device.

[0030] In combination with any one of the solutions in the first aspect and the second aspect, the information transmitted in each of the N time periods is the information to be transmitted.

[0031] When the sending device sends the information to be transmitted to the receiving device by repeated transmission, through the above scheme, when the channel quality corresponding to some frequencies is poor, the receiving device can receive the information to be transmitted through other frequencies, thereby ensuring that the data transmission between the sending device and the receiving device can proceed normally.

[0032] In combination with the solution described in any one of the first aspect and the second aspect, a mapping rule corresponding to each of the N time periods is predefined.

[0033] In this way, the signaling overhead between the sending device and the receiving device can be saved.

[0034] In combination with any one of the solutions in the first aspect and the second aspect, the mapping rules corresponding to each of the N time periods are different.

[0035] In this way, the frequency diversity gain of signal transmission can be further guaranteed.

[0036] In combination with any one of the solutions in the first aspect and the second aspect, the configuration information is sent in a manner including at least one of unicast and broadcast.

[0037] According to a third aspect, a communication device is provided, which may be a network device, or a device in a network device (eg, a chip, or a chip system, or a circuit), or a device that can be used in conjunction with a network device.

[0072] First, a communication system to which the embodiments of the present application are applicable is described.

[0073] Figure 1 1 is a schematic diagram of a communication system 100 applicable to an embodiment of the present application. Figure 1 As shown, the communication system 100 includes: a network device 110 and a terminal device 120. Uplink and downlink data can be transmitted between the network device 110 and the terminal device 120. Exemplarily, the network device 110 sends downlink data to the terminal device 120, and the terminal device 120 sends uplink data to the network device 110.

[0074] The terminal device 120 is a device with wireless transceiver functions, which may 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 120 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 remote medical device, or a wireless terminal in medical equipment.

[0075] The communication device for implementing the function of the terminal device 120 may be a terminal device, or a device capable of supporting the terminal device to implement the function, such as a chip system. The device may be installed in the terminal device or used in conjunction with the terminal device. In the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0076] The network device 110 is a device with wireless transceiver functions, which is used to communicate with the terminal device 120. The network device 110 can be a node in a 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 a 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.

[0082] Next, a brief description of some of the technical contents involved in this application is given.

[0083] 1. On-off keying (OOK) modulation

[0084] Figure 2 This is a waveform diagram of the signal when it is modulated using OOK. Figure 2 As shown, when the signal is modulated using OOK, each bit (i.e., the encoded bit) corresponds to a symbol. Similarly, a symbol can also be called a chip, or other names, which are not limited here. When the bit is 1, a signal is sent within the symbol length (i.e., the signal transmission power within the symbol length is not 0). When the bit is 0, no signal is sent within the symbol length (i.e., the signal transmission power within the symbol length is 0). As shown in Figure 2 As shown, Figure 2 The waveform shown may represent 1010 four bits.

[0085] 2. Frequency shift keying (FSK) modulation

[0086] Figure 3 It is a waveform schematic diagram when the signal adopts FSK modulation. As Figure 3 shown, when the signal adopts FSK modulation, different information uses different frequency resources. For example, 2FSK carries 1-bit information. When the information bit is 0, the information is sent on the frequency resource F0 and not sent on the frequency resource F1; when the information bit is 1, the information is sent on the frequency resource F1 and not sent on the frequency resource F0. Assuming F0 < F1, the waveform of the FSK signal with the information 0101 is as Figure 3 shown. In the first symbol and the third symbol, the frequency of the signal is lower, and in the second symbol and the fourth symbol, the frequency of the signal is higher. When the receiving end demodulates the signal, it can compare the power levels on F0 and F1 to determine whether the sent information is 0 or 1.

[0087] As can be seen from the description of the background technology, the data transmission between the network device 110 and the terminal device 120 is greatly affected by the channel quality. Exemplarily, when the network device 110 sends the downlink data 1 to the terminal device 120 through frequency a, if the channel quality corresponding to frequency a is poor, the terminal device 120 may not be able to receive the downlink data 1. Another example is that when the network device 110 sends the downlink data 1 to the terminal device 120 in a repeated transmission manner, if each repeated transmission is based on frequency a and the channel quality corresponding to frequency a is poor, the terminal device 120 may also not be able to receive the downlink data 1. In summary, the channel quality has a great impact on data transmission.

[0088] In view of this, the present application provides a communication method and apparatus, which can effectively reduce the impact of channel quality on data transmission.

[0089] The communication method of the embodiments of the present application is described below.

[0090] Figure 4 It is an interaction process schematic diagram of the communication method 400 of the embodiments of the present application. The method 400 can be executed by the sending device and the receiving device, or by modules and / or devices (such as chips or integrated circuits, etc.) with corresponding functions installed in the sending device and the receiving device, which is not limited. The following describes it by taking the sending device and the receiving device as examples. The sending device is the network device 110 and the receiving device is the terminal device 120, or the sending device is the terminal device 120 and the receiving device is the network device 110, which is not limited. The method 400 includes:

[0091] S410. The sending device determines the information 1 to be transmitted.

[0092] Specifically, the information to be transmitted 1 is original information, that is, the information to be transmitted 1 is information that the sending device needs to send to the receiving device, and is also information that the receiving device needs to obtain. In one example, the information to be transmitted 1 is a bit sequence, such as 0110110101.

[0093] S420: The sending device sends the information to be transmitted 1 to the receiving device within N time periods.

[0094] Correspondingly, the receiving device receives the information 1 to be transmitted within N time periods.

[0095] It can be understood that each time period in N time periods can be used to transmit information in the information 1 to be transmitted. For example, the i-th time period is used to transmit information 1 (such as the first information), and the p-th time period is used to transmit information 2 (such as the second information). The information transmitted in each time period can be associated with a frequency (regardless of whether it is one frequency or multiple frequencies). Exemplarily, information 1 is associated with frequency 1 (such as the first frequency), and information 2 is associated with frequency 2 (such as the second frequency). N is a positive integer greater than 1, i and p are both positive integers less than or equal to N, and i is not equal to p. The i-th time period and the p-th time period are both any time periods in the N time periods. The information 1 to be transmitted includes information 1 and information 2.

[0096] It should be noted that different time periods can be continuous or discontinuous in time, that is, there are time intervals. When the N time periods are continuous in time, the sending device can send the information to be transmitted 1 to the receiving device as quickly as possible. When the N time periods are discontinuous in time, the receiving device can process the received information at a certain time interval.

[0097] In one possible implementation, information transmitted in at least two of the N time periods is associated with different frequencies. Taking the i-th time period and the p-th time period as examples, information 1 transmitted in the i-th time period is associated with frequency 1, and information 2 transmitted in the p-th time period is associated with frequency 2, and frequency 1 and frequency 2 are different.

[0098] For example, when frequency 1 and frequency 2 refer to a specific frequency value respectively, frequency 1 and frequency 2 are different, that is, the frequency value referred to by frequency 1 (such as f 1 ) and the frequency value referred to by frequency 2 (such as f 2) are different. When frequency 1 and frequency 2 refer to a group of frequency values ​​respectively, frequency 1 and frequency 2 are different if: the frequency ordering of the group of frequency values ​​referred to by frequency 1 is different from the frequency ordering of the group of frequency values ​​referred to by frequency 2; or, the group of frequency values ​​referred to by frequency 1 is different from the group of frequency values ​​referred to by frequency 2 (at least one frequency value in the group of frequency values ​​referred to by frequency 1 does not belong to the group of frequency values ​​referred to by frequency 2, or at least one frequency value in the group of frequency values ​​referred to by frequency 2 does not belong to the group of frequency values ​​referred to by frequency 1); or, the group of frequencies referred to by frequency 1 and the group of frequencies referred to by frequency 2 have at least one different frequency at the same sorting position. Exemplarily, frequency 1 refers to a group of frequency values ​​{f 0 , f 1 , f 2}, frequency 2 refers to a set of frequency values ​​{f 1 , f 2 , f 0}; or, frequency 1 refers to a set of frequency values ​​{f 0 , f 1 , f 2}, frequency 2 refers to a set of frequency values ​​{f 1 , f 2 , f 3}; or, frequency 1 refers to a set of frequency values ​​{f 0 , f 1 , f 1}, frequency 2 refers to a set of frequency values ​​{f 0 , f 1 , f 2}.

[0099] In the above content, information 1 and information 2 may be the same or different. When information 1 and information 2 are the same, the sending device sends the same information through different frequencies, which can effectively reduce the impact of channel quality on data transmission. For example, when the channel quality corresponding to frequency 1 is poor, the receiving device can receive information 2 through frequency 2; when the channel quality corresponding to frequency 2 is poor, the receiving device can receive information 1 through frequency 1. When information 1 and information 2 are different, the sending device sends different information through different frequencies, which can effectively reduce the impact of channel quality on data transmission. For example, when the channel quality corresponding to frequency 1 is poor, the receiving device can receive information 2 through frequency 2 and only lose information 1; when the channel quality corresponding to frequency 2 is poor, the receiving device can receive information 1 through frequency 1 and only lose information 2.

[0100] In the above content, the sending device can send the information 1 to be transmitted to the receiving device based on any modulation method such as OOK modulation and FSK modulation, as described below for details.

[0101] In a possible implementation, frequency 1 is determined by the sending device based on mapping rule 1 and information 1, and frequency 2 is determined by the sending device based on mapping rule 2 and information 2. Mapping rule 1 is different from mapping rule 2. Mapping rule 1 is used to indicate the association between information 1 and frequency 1, and mapping rule 2 is used to indicate the association between information 2 and frequency 2. For a description of mapping rule 1 and mapping rule 2, see Table 1.

[0102] Table 1

[0103]

[0104]

[0105] As shown in Table 1, for example, for mapping rule 1, bit 00 is mapped to f 0 , bits 01 are mapped to f 1 , bit 10 is mapped to f 2 , bit 11 is mapped to f 3 ; For mapping rule 2, bit 00 is mapped to f 1 , bits 01 are mapped to f 2 , bit 10 is mapped to f 3 , bit 11 is mapped to f 0 .

[0106] When information 1 and information 2 are the same, both are bits 00, the sending device determines frequency 1 as f based on mapping rule 1 and information 1. 0 , the sending device determines frequency 2 as f based on mapping rule 2 and information 2 1 When information 1 and information 2 are the same, both are bits 0110110101, the transmitting device determines frequency 1 as {f 1 , f 2 , f 3 , f 1 , f 1}, the sending device determines frequency 2 as {f 2 , f 3 , f 0 , f 2 , f 2 When information 1 is bit 01 and information 2 is bit 10, the transmitting device determines frequency 1 as {f 1}, the sending device determines frequency 2 as {f 3}.

[0107] From the above content, it can be seen that the sending device determines the frequency 1 and frequency 2 corresponding to information 1 and information 2 respectively based on different mapping rules, and frequency 1 and frequency 2 are different. Since the first mapping rule is different from the second mapping rule, the frequency associated with the information can be randomized to avoid the same frequency from being reused, thereby obtaining a greater frequency diversity gain, and then effectively reducing the impact of channel quality on data transmission.

[0108] In the above content, the sending device needs to map the information to be transmitted 1 to the frequency to obtain a signal, and send the signal to the receiving device, so that the receiving device can obtain the information to be transmitted 1. Therefore, the sending device sends the information to be transmitted 1 to the receiving device within N time periods, which may include:

[0109] #a, map information 1 to frequency 1 to obtain signal 1; map information 2 to frequency 2 to obtain signal 2;

[0110] #b. During the i-th period of time, signal 1 is sent to the receiving device; during the p-th period of time, signal 2 is sent to the receiving device.

[0111] Correspondingly, the receiving device receives signal 1 during the i-th period of time and receives signal 2 during the p-th period of time.

[0112] Specifically, since frequency 1 is different from frequency 2, the frequencies mapped to information in different time periods can be different, avoiding the same frequency from being reused, thereby obtaining a greater frequency diversity gain, and effectively reducing the impact of channel quality on data transmission.

[0113] It should be noted that the above content is described by taking the example that the sending device sends signal 1 and signal 2 to the receiving device in the i-th time period and the p-th time period respectively, but is not limited to this.

[0114] S430: The receiving device processes the information 1 to be transmitted.

[0115] Specifically, the receiving device receives N signals rather than the original information in N time periods. The receiving device needs to process the received signals to obtain the information to be transmitted 1.

[0116] Specifically, the receiving device receives the signal in the i-th time segment and the p-th time segment, and demodulates the information according to mapping rule 1 and mapping rule 2. In the i-th time segment, the activation frequency is determined to be frequency 1 through detection, and the sent information is demodulated to be information 1 according to the activation frequency 1 and mapping rule 1; in the p-th time segment, the activation frequency is determined to be frequency 2 through detection, and the sent information is demodulated to be information 2 according to the activation frequency 2 and mapping rule 2.

[0117] Furthermore, the receiving device processes the acquired information to be transmitted 1, for example, sends feedback information to the sending device according to the acquired information to be transmitted 1.

[0118] In summary, by using different frequencies to transmit information, the frequency diversity gain of signal transmission can be improved, avoiding the situation where the entire information is lost due to poor channel quality corresponding to a certain frequency, thereby effectively reducing the impact of channel quality on data transmission.

[0119] The modulation method of the information 1 to be transmitted is described below.

[0120] Figure 5 The FSK modulation method is used as an example to describe. Figure 6 Yes Figure 5 An example description of the technical solution described. Figure 7 The OOK modulation method is used as an example. Figure 8 Yes Figure 7 An example description of the technical solution is given. It should be noted that: Figure 5 and Figure 7 The description is made by taking the example that the sending device repeatedly transmits the information 1 to be transmitted to the receiving device four times.

[0121] Figure 5 : is a schematic diagram of the interaction flow of the communication method 500 of an embodiment of the present application. The method 500 includes:

[0122] S510. The sending device activates frequency 1 according to mapping rule 1 and information 1 to obtain signal 1, and activates frequency 2 according to mapping rule 2 and information 2 to obtain signal 2; and activates frequency 3 according to mapping rule 3 and information 3 to obtain signal 3; and activates frequency 4 according to mapping rule 4 and information 4 to obtain signal 4. Each of the above frequencies 1 to 4 can be used to refer to a frequency or a group of frequencies, which is not limited.

[0123] Specifically, information 1, information 2, information 3 and information 4 are all bit sequences 00011011. For descriptions of mapping rules 1 to 4, see Table 2.

[0126] As shown in Table 2, the sending device determines, according to mapping rule 1 and information 1, that frequency 1 is {f 0 , f 1 , f 2 , f 3}, and activates frequency 1 through FSK modulation to obtain signal 1. The sending device determines frequency 2 as {f 1 , f 2 , f 3 , f 0}, and activates frequency 2 through FSK modulation to obtain signal 2. The sending device determines frequency 3 as {f 2 , f 3 , f 0 , f 1}, and activates frequency 3 through FSK modulation to obtain signal 3. Correspondingly, the sending device determines frequency 4 as {f 3 , f 0 , f 1 , f 2}, and activate frequency 4 through FSK modulation to obtain signal 4.

[0127] S520 . The sending device sends signal 1 in time period 1 , sends signal 2 in time period 2 , sends signal 3 in time period 3 , and sends signal 4 in time period 4 .

[0128] Accordingly, the receiving device receives signal 1 in time period 1, receives signal 2 in time period 2, receives signal 3 in time period 3, and receives signal 4 in time period.

[0129] In time period 1, the sending device uses mapping rule 1 to map information and activation frequency, and obtains signal 1; in time period 2, the sending device uses mapping rule 2 to map information and activation frequency, and obtains signal 2; in time period 3, the sending device uses mapping rule 3 to map information and activation frequency, and obtains signal 3; in time period 4, the sending device uses mapping rule 4 to map information and activation frequency, and obtains signal 4. For details, see Figure 6 .

[0130] Figure 6 Schematic diagram of a mapping relationship between information and frequency in the embodiment of the present application. Figure 6 As shown, in time period 1, the sending devices activate f 0 、f 1 、f 2 、f 3 ; In time period 2, the sending devices activate f in turn 1 、f 2 、f 3 、f 0 ; In time period 3, the sending devices activate f in turn 2 、f 3 、f 0 、f 1; In time period 4, the sending devices activate f in turn 3 、f 0 、f 1 、f 2 For the activation method, please refer to the above description of the FSK modulation method, which will not be repeated here.

[0131] More specifically, during time period 1, the sending device activates f 0 、f 1 、f 2 、f 3 The transmission of bits 00, 01, 10, and 11 is realized respectively, thereby completing the transmission of information 1 to be transmitted. In time period 2, the sending device activates f 1 、f 2 、f 3 、f 0 The transmission of bits 00, 01, 10, and 11 is realized respectively, thereby completing the secondary repetitive transmission of the information 1 to be transmitted. In time period 3, the sending device activates f 2 、f 3 、f 0 、f 1 The transmission of bits 00, 01, 10, and 11 is realized respectively, thereby completing the three-fold repetition of the information 1 to be transmitted. In time period 4, the sending device activates f 3 、f 0 、f 1 、f 2 The bit 00, bit 01, bit 10 and bit 11 are transmitted respectively, thereby completing four repeated transmissions of the information 1 to be transmitted.

[0132] From the above content, it can be seen that bits 00 are activated by f 0 、f 1 、f 2 、f 3 For transmission, bits 01 are respectively transmitted by activating f 1 、f 2 、f 3 、f 0 For transmission, bit 10 is transmitted by activating f 2 、f 3 、f 0 、f 1 For transmission, bits 11 are respectively transmitted by activating f 3 、f 0 、f 1 、f 2 If f 0 The corresponding channel quality is poor, and the sending device can also activate f 1 、f2 、f 3 Bit 00, bit 01, bit 10, and bit 11 are transmitted to the receiving device, which can effectively reduce the impact of channel quality on data transmission.

[0133] S530: The receiving device processes signal 1, signal 2, signal 3, and signal 4.

[0134] Specifically, the receiving device processes signals 1 to 4 to obtain information 1 to be transmitted.

[0135] By using different frequencies to transmit information, the frequency diversity gain of signal transmission can be improved, avoiding the situation where the entire information is lost due to poor channel quality corresponding to a certain frequency, thereby effectively reducing the impact of channel quality on data transmission.

[0136] The above content is described using the FSK modulation method as an example, and the OOK modulation method is described below.

[0137] Figure 7 700 is a schematic diagram of an interaction process of a communication method 700 according to an embodiment of the present application. The method 700 includes:

[0138] S710. The sending device determines frequency 1 according to mapping rule 1 and information 1, performs OOK modulation on information 1 at frequency 1, and obtains signal 1; determines frequency 2 according to mapping rule 2 and information 2, performs OOK modulation on information 2 at frequency 2, and obtains signal 2; determines frequency 3 according to mapping rule 3 and information 3, performs OOK modulation on information 3 at frequency 3, and obtains signal 3; and determines frequency 4 according to mapping rule 4 and information 4, performs OOK modulation on information 4 at frequency 4, and obtains signal 4. Each of the above frequencies 1 to 4 can be used to refer to a frequency or a group of frequencies, which is not limited.

[0139] Specifically, in order to improve transmission efficiency, the transmitting device can use multiple channels to transmit the information 1 to be transmitted in parallel at the same time. Four parallel channels are used as an example for description. Each channel transmits two bits at a time, and the transmitting device can transmit 8 bits in parallel at a time. For example, information 1 to information 4 are bit sequences of 00011011, and the details can be seen in Table 3.

[0142] As shown in Table 3, the sending device determines, according to mapping rule 1 and information 1, that frequency 1 is {f 0 , f 1 , f 2 , f3}, and performs OOK modulation on information 1 on frequency 1 to obtain signal 1. The sending device determines frequency 2 as {f 1 , f 2 , f 3 , f 0}, and performs OOK modulation on information 2 at frequency 2 to obtain signal 2. The sending device determines frequency 3 as {f 2 , f 3 , f 0 , f 1}, and performs OOK modulation on information 3 at frequency 3 to obtain signal 3. The sending device determines frequency 4 as {f 3 , f 0 , f 1 , f 2}, and perform OOK modulation on information 4 at frequency 4 to obtain signal 4. For details, please refer to Figure 8 .

[0143] Figure 8 FIG. 1 is another schematic diagram of the mapping relationship between information and frequency in an embodiment of the present application. Figure 8 As shown, in time period 1, the sending device is at f 0 OOK modulation is performed on the first and second bits of information 1, and bit 00 is transmitted; at f 1 The third and fourth bits in information 1 are OOK modulated and bit 01 is transmitted; at f 2 The fifth and sixth bits in information 1 are OOK modulated and bit 10 is transmitted; at f 3 The seventh and eighth bits in information 1 are OOK modulated and bit 11 is transmitted. In time period 2, the sending device performs OOK modulation on the seventh and eighth bits in information 1 and transmits bit 11. 1 OOK modulation is performed on the first and second bits of information 1, and bit 00 is transmitted; at f 2 The third and fourth bits in information 1 are OOK modulated and bit 01 is transmitted; at f 3 The fifth and sixth bits in information 1 are OOK modulated and bit 10 is transmitted; at f 0 The seventh and eighth bits in information 1 are OOK modulated and bit 11 is transmitted. In time period 3, the sending device performs OOK modulation on f 2 OOK modulation is performed on the first and second bits of information 1, and bit 00 is transmitted; at f 3 The third and fourth bits in information 1 are OOK modulated and bit 01 is transmitted; at f 0The fifth and sixth bits in information 1 are OOK modulated and bit 10 is transmitted; at f 1 The seventh and eighth bits in information 1 are OOK modulated and bit 11 is transmitted. In time period 4, the sending device performs OOK modulation on f 3 OOK modulation is performed on the first and second bits of information 1, and bit 00 is transmitted; at f 0 The third and fourth bits in information 1 are OOK modulated and bit 01 is transmitted; at f 1 The fifth and sixth bits in information 1 are OOK modulated and bit 10 is transmitted; at f 2 The seventh and eighth bits in information 1 are OOK modulated, and bit 11 is transmitted.

[0144] More specifically, during time period 1, the sending device transmits the 0 、f 1 、f 2 、f 3 The transmission of bits 00, 01, 10, and 11 is realized simultaneously, thereby completing the transmission of information 1 to be transmitted. In time period 2, the sending device transmits information 1 through f 1 、f 2 、f 3 、f 0 The bit 00, bit 01, bit 10 and bit 11 are transmitted simultaneously, thereby completing the secondary repeated transmission of the information 1 to be transmitted. In time period 3, the sending device transmits the information 1 through f 2 、f 3 、f 0 、f 1 The transmission of bits 00, 01, 10, and 11 is realized simultaneously, thereby completing the three-fold repetition of the information 1 to be transmitted. In time period 4, the sending device transmits the information 1 through f 3 、f 0 、f 1 、f 2 The bit 00, bit 01, bit 10 and bit 11 are transmitted simultaneously, thereby completing four repeated transmissions of the information 1 to be transmitted.

[0145] From the above content, we can see that bits 00 are respectively transmitted through f 0 、f 1 、f 2 、f 3 For transmission, bits 01 are transmitted through f 1 、f 2 、f 3 、f 0 For transmission, bits 10 are transmitted through f 2 、f 3、f 0 、f 1 For transmission, bits 11 are transmitted through f 3 、f 0 、f 1 、f 2 If f 0 The corresponding channel quality is poor, and the sending device can also pass f 1 、f 2 、f 3 Bit 00, bit 01, bit 10, and bit 11 are transmitted to the receiving device, which can effectively reduce the impact of channel quality on data transmission.

[0146] S720. The sending device sends signal 1 in time period 1, sends signal 2 in time period 2, sends signal 3 in time period 3, and sends signal 4 in time period 4.

[0147] Accordingly, the receiving device receives signal 1 in time period 1, receives signal 2 in time period 2, receives signal 3 in time period 3, and receives signal 4 in time period.

[0148] S730: The receiving device processes signal 1, signal 2, signal 3, and signal 4.

[0149] Specifically, the receiving device processes signals 1 to 4 to obtain information 1 to be transmitted.

[0150] By using different frequencies to transmit information, the frequency diversity gain of signal transmission can be improved, avoiding the situation where the entire information is lost due to poor channel quality corresponding to a certain frequency, thereby effectively reducing the impact of channel quality on data transmission.

[0151] It should be noted that method 400, method 500 and method 700 mainly describe that the sending device uses different mapping rules to obtain different frequencies, thereby transmitting information through different frequencies, thereby effectively reducing the impact of channel quality on data transmission. In addition, the embodiments of the present application also support obtaining different frequencies through other methods and the same mapping rules, and can also transmit information through different frequencies, thereby effectively reducing the impact of channel quality on data transmission.

[0152] In a possible implementation, the sending device scrambles information 1 using scrambling code sequence 1 to obtain scrambled information 1, and the sending device scrambles information 2 using scrambling code sequence 2 to obtain scrambled information 2, where scrambling code sequence 1 is different from scrambling code sequence 2. The sending device determines frequency 1 according to mapping rule 1 and scrambled information 1, and determines frequency 2 according to mapping rule 1 and scrambled information 2, where frequency 1 is different from frequency 2.

[0153] Exemplarily, when information 1 and information 2 are the same, both are bits 00, the transmitting device uses the same mapping rule 1 for information 1 and information 2. However, before mapping, the transmitting device performs a modulo 2 addition operation on information 1 and the scrambling sequence 00 to obtain 00, and determines frequency 1 as f based on mapping rule 1 (see Table 1) and the scrambled information 1. 0 The sending device performs a modulo 2 addition operation on the information 2 and the scrambling sequence 01 to obtain 01, and determines the frequency 2 to be f based on the mapping rule 1 and the scrambled information 2. 1 When information 1 and information 2 are the same, both are bit sequences 0110110101, the transmitting device uses the same mapping rule 1 for information 1 and information 2. However, before mapping, the transmitting device performs a modulo 2 addition operation on information 1 and the scrambling sequence 0000000000 to obtain the scrambled information 1, which is 0110110101, and determines frequency 1 as {f 1 , f 2 , f 3 , f 1 , f 1 The sending device performs a modulo-2 addition operation on the information 2 and the scrambling sequence 1101111111 to obtain the scrambled information 2, which is: 1011001010, and determines the frequency 2 as {f 2 , f 3 , f 0 , f 2 , f 2}.

[0154] It should be noted that the sending device can configure a scrambling code sequence for the information transmitted in each of the N time periods (at least two scrambling code sequences are different), and use the scrambling code sequence to scramble the information transmitted in the corresponding time period. After being processed by the same mapping rule, the embodiment of the present application supports that the information transmitted in at least two time periods is transmitted through different frequencies, so that the impact of channel quality on data transmission can be effectively reduced.

[0155] It should also be noted that the sending device can transmit the information 1 to be transmitted to the receiving device in combination with different mapping rules and scrambling processing schemes. For example, the sending device first performs scrambling processing on information 1 and information 2 respectively, and then uses mapping rule 1 and mapping rule 2 to map the information to the frequency, and finally sends the scrambled information to the receiving device. In this way, it can be further ensured that different frequencies are used to transmit information, effectively reducing the impact of channel quality on data transmission.

[0156] In another possible implementation, the transmitting device performs a first number of cyclic shifts on information 1 to obtain cyclically shifted information 1, and performs a second number of cyclic shifts on information 2 to obtain cyclically shifted information 2, wherein the first number of cyclic shifts is different from the second number of cyclic shifts. The transmitting device determines frequency 1 according to mapping rule 1 and cyclically shifted information 1, and determines frequency 2 according to mapping rule 1 and cyclically shifted information 2, wherein frequency 1 is different from frequency 2.

[0157] Exemplarily, when information 1 and information 2 are the same, both are bit sequences 00011011, the transmitting device uses the same mapping rule 1 for information 1 and information 2. However, before mapping, the transmitting device processes information 1 and information 2 using different interleaving or cyclic shifting. Specifically, the transmitting device determines the frequency according to mapping rule 1 (see Table 1). However, before mapping, the transmitting device performs a cyclic shift of 0 bits on information 1 (such as a first number of cyclic shifts), and the information 1 after the cyclic shift is 00011011, and determines the frequency 1 to be {f 0 , f 1 , f 2 , f 3 , f 3 The transmitting device performs a 2-bit cyclic shift on information 2 (such as a second number of cyclic shifts), and the cyclically shifted information 2 is 01101100, and determines frequency 2 as {f based on mapping rule 1 and the cyclically shifted information 2. 1 , f 2 , f 3 , f 0 , f 0}.

[0158] It should be noted that the sending device can perform cyclic shift for the information transmitted in each of the N time periods (the number of bits of at least two cyclic shifts is different), and after being processed by the same mapping rule, the embodiment of the present application supports the information transmitted in at least two time periods to be transmitted through different frequencies. In this way, the impact of channel quality on data transmission can be effectively reduced.

[0159] It should also be noted that the sending device can combine different mapping rules for cyclic shift processing, and then use mapping rule 1 and mapping rule 2 to map information and frequency, and finally send the information to the receiving device. In this way, it can further ensure that different frequencies are used to transmit information, effectively reducing the impact of channel quality on data transmission.

[0160] In addition, in the above description of method 400, method 500 and method 700, the sending device may also send configuration information 1 to the receiving device, and the configuration information 1 is used to configure the transmission parameters of the information to be transmitted 1. The configuration information 1 includes at least one of the following: the number of transmissions, the modulation mode, the modulation order, the time interval, whether repeated transmission is adopted, the mapping rule between information and frequency, the starting time slot and cycle of detection, etc. In this way, it is beneficial for the receiving device to better receive the information to be transmitted 1.

[0161] Specifically, the configuration information 1 may be carried in a system information block (SIB) or in radio resource configuration information (RRC), without limitation.

[0162] In a possible implementation, the sending device sends configuration information 1 to the receiving device via unicast or broadcast, which is not limited.

[0163] In the above descriptions of method 400, method 500, and method 700, each time period may be associated with a mapping rule. The sending device may also send the mapping rule associated with each time period to the receiving device, or the mapping rule associated with each time period is predefined, so that the receiving device can obtain the mapping relationship between information and frequency, and the receiving device can better obtain the information to be transmitted 1.

[0164] In a possible implementation, the mapping relationship corresponding to each of the N time periods is different, so that the influence of the channel quality on the data transmission can be reduced as much as possible.

[0165] Through the above content, the embodiments of the present application describe how to transmit information through different frequencies, thereby improving the frequency diversity gain of signal transmission, avoiding the loss of the entire information due to poor channel quality corresponding to a certain frequency, and effectively reducing the impact of channel quality on data transmission.

Whether one of the above functions is executed in the form of a hardware structure, a software module, or a hardware structure plus a software module depends on the specific application and design constraints of the technical solution.
