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 19, 2023, with application number 202310734557.7 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] In the field of communications, data transmission between network devices and terminal devices is significantly 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, potentially affecting normal communication between the terminal device and the network device. Therefore, effectively reducing the impact of channel quality on data transmission is a pressing technical issue.
[0004] Summary of the Invention
[0005] The present application provides a communication method and apparatus that can effectively reduce the impact of channel quality on data transmission.
[0006] In a first aspect, a communication method is provided, comprising: determining information to be transmitted; transmitting the information to be transmitted to a receiving device within N time periods, wherein first information transmitted within the i-th time period of the N time periods is associated with a first frequency, and second information transmitted within the p-th time period of the N time periods is associated with a second frequency, where 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; and the first frequency and the second frequency are different. The information to be transmitted includes the first information and the second information.
[0007] The execution subject of the solution described in the first aspect is a sending device, or a module or chip used to execute the functions of the sending device, etc., which is not limited to this. For ease of description, the following description takes the sending device as an example.
[0008] 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.
[0009] 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, and thus effectively reducing the impact of channel quality on data transmission.
[0010] In one 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.
[0011] Specifically, since the first mapping rule is different from the second mapping rule, the frequency associated with the information can be randomized, 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 send information to be transmitted to a receiving device within N time periods, including: mapping the first information to a first frequency to obtain a first signal, and mapping the 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.
[0013] 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.
[0014] 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.
[0015] In this way, the present application supports the sending device to generate a signal for transmission through frequency shift keying modulation.
[0016] 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 the 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.
[0017] In this way, the present application supports the sending device to generate a signal for transmission through on-off keying modulation.
[0018] 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.
[0019] In this way, the receiving device can better receive the information to be transmitted.
[0020] In a possible implementation, the method further includes: sending a mapping rule corresponding to each time period in the N time periods to a receiving device.
[0021] 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.
[0022] In a second aspect, a communication method is provided, including: receiving information to be transmitted sent by a sending device within N time periods, the first information transmitted within the i-th time period in the N time periods is associated with a first frequency, and the second information transmitted within the p-th time period in 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 the first information and the second information, and the first frequency is different from the second frequency; and processing the information to be transmitted.
[0023] The execution subject of the solution described in the second aspect is a receiving device, or a module or chip used to perform the functions of the receiving device, etc., which is not limited to this. For ease of description, the following description takes the receiving device as an example.
[0024] 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.
[0025] 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, and thus effectively reducing the impact of channel quality on data transmission.
[0026] In one possible implementation, the first frequency is determined by the transmitting device based on a first mapping rule and the first information, where the first mapping rule indicates an association between the first information and the first frequency; and the second frequency is determined by the transmitting device based on a second mapping rule and the second information, where the second mapping rule indicates an association between the second information and the second frequency. The first mapping rule and the second mapping rule are different.
[0027] A possible implementation method is to receive information to be transmitted sent by a sending device within N time periods, including: during the i-th time period, receiving a first signal sent by the sending device, where the first signal is a signal obtained by the sending device mapping the first information to a first frequency; and during the p-th time period, receiving a second signal sent by the sending device, where the second signal is a signal obtained by the sending device mapping the second information to a second frequency.
[0028] 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.
[0029] 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.
[0030] In a possible implementation, the method further includes: receiving configuration information sent by a sending 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.
[0031] In a possible implementation, the method further includes: receiving a mapping rule corresponding to each of the N time periods sent by the sending device.
[0032] 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.
[0033] When the sending device uses repeated transmission to send information to the receiving device, 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 data transmission between the sending device and the receiving device can proceed normally.
[0034] In combination with the solution described in any one of the first aspect and the second aspect, the mapping rule corresponding to each of the N time periods is predefined.
[0035] In this way, the signaling overhead between the sending device and the receiving device can be saved.
[0036] 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.
[0037] In this way, the frequency diversity gain of signal transmission can be further guaranteed.
[0038] 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.
[0039] On the third aspect, a communication device is provided, which may be a network device, or a device in a network device (for example, a chip, or a chip system, or a circuit), or a device that can be used in conjunction with a network device.

[0074] First, a communication system to which the embodiments of the present application are applicable is described.
[0075] Figure 1 is a schematic diagram of a communication system 100 applicable to an embodiment of the present application. As shown in Figure 1 , communication system 100 includes a network device 110 and a terminal device 120. Uplink and downlink data can be transmitted between network device 110 and terminal device 120. For example, network device 110 sends downlink data to terminal device 120, and terminal device 120 sends uplink data to network device 110.
[0076] The terminal device 120 is a device with wireless transceiver functions, which can be referred to as 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 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 remote medical device, or a similar device.

[0077] The communication device used to implement the functions of the terminal device 120 can be a terminal device, or 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.
[0078] 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 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 a 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.
[0079] 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.

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 function 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.

[0081] The communication device used to implement the functions of the network device 110 can be a network device, or a device that can support the network device to implement the functions, such as a chip system.

[0084] Next, a brief description of some of the technical contents involved in this application is given.
[0085] 1. On-off keying (OOK) modulation
[0086] Figure 2 is a waveform diagram of a signal using OOK modulation. As shown in Figure 2, 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, without limitation. When the bit is 1, a signal is transmitted 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 transmitted within the symbol length (i.e., the signal transmission power within the symbol length is 0). As shown in Figure 2, the waveform shown in Figure 2 can represent four bits of 1010.
[0087] 2. Frequency Shift Keying (FSK) Modulation
[0088] Figure 3 is a schematic waveform diagram when the signal uses FSK modulation. As shown in Figure 3, when the signal uses 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 frequency resource F0 and not sent on frequency resource F1; when the information bit is 1, the information is sent on frequency resource F1 and not sent on frequency resource F0. Assuming F0 < F1, the waveform of the FSK signal with information 0101 is shown in Figure 3. In the first and third symbols, the frequency of the signal is lower, and in the second and fourth symbols, 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 transmitted information is 0 or 1.
[0089] As can be seen from the description of the background art, 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. Also exemplarily, when the network device 110 sends the downlink data 1 to the terminal device 120 by means of repeated transmission, 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.
[0090] 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.
[0091] The communication method of the embodiments of the present application is described below.
[0092] Figure 4 is a schematic interaction flow diagram of the communication method 400 according to an embodiment of the present application. The method 400 can be executed by a sending device and a 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:
[0093] S410. The sending device determines the information 1 to be transmitted.
[0094] Specifically, the information 1 to be transmitted is the original information, that is, the information 1 to be transmitted is the information that the sending device needs to send to the receiving device and is also the information that the receiving device needs to obtain. In one example, the information 1 to be transmitted is a bit sequence, such as 0110110101, etc.
[0095] S420: The sending device sends the information to be transmitted 1 to the receiving device within N time periods.
[0096] Correspondingly, the receiving device receives the information 1 to be transmitted within N periods of time.
[0097] It can be understood that each time period within the N time periods can be used to transmit information in the information to be transmitted 1. 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). For example, 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 to be transmitted 1 includes information 1 and information 2.
[0098] It should be noted that different time periods can be continuous or discontinuous, that is, there are time intervals. When the N time periods are continuous, the sending device can send the to-be-transmitted information 1 to the receiving device as quickly as possible. When the N time periods are discontinuous, the receiving device can process the received information at certain intervals.
[0099] 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. Frequency 1 and frequency 2 are different.
[0100] As an example, when frequency 1 and frequency 2 each refer to a specific frequency value, frequency 1 and frequency 2 are different if: the frequency value referred to by frequency 1 (such as f1) is different from the frequency value referred to by frequency 2 (such as f2). When frequency 1 and frequency 2 each refer to a group of frequency values, frequency 1 and frequency 2 are different if: the frequency sorting of the group of frequency values referred to by frequency 1 is different from the frequency sorting 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 {f0, f1, f2}, and frequency 2 refers to a group of frequency values {f1, f2, f0}; or, frequency 1 refers to a group of frequency values {f0, f1, f2}, and frequency 2 refers to a group of frequency values {f1, f2, f3}; or, frequency 1 refers to a group of frequency values {f0, f1, f1}, and frequency 2 refers to a group of frequency values {f0, f1, f2}.
[0101] In the above content, information 1 and information 2 can be the same or different. When information 1 and information 2 are the same, the transmitting device sends the same information over different frequencies, which effectively reduces 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 over frequency 2; when the channel quality corresponding to frequency 2 is poor, the receiving device can receive information 1 over frequency 1. When information 1 and information 2 are different, the transmitting device sends different information over different frequencies, which effectively reduces 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 over frequency 2 and only lose information 1; when the channel quality corresponding to frequency 2 is poor, the receiving device can receive information 1 over frequency 1 and only lose information 2.
[0102] In the above content, the sending device can send the information to be transmitted 1 to the receiving device based on any modulation method such as OOK modulation and FSK modulation. Please refer to the following description for details.
[0103] In one possible implementation, the transmitting device determines frequency 1 based on mapping rule 1 and information 1, and determines frequency 2 based on mapping rule 2 and information 2. Mapping rule 1 is different from mapping rule 2. Mapping rule 1 indicates the association between information 1 and frequency 1, and mapping rule 2 indicates the association between information 2 and frequency 2. For a description of mapping rule 1 and mapping rule 2, see Table 1.
[0104] Table 1
[0105] As shown in Table 1, exemplarily, for mapping rule 1, bit 00 is mapped to f0, bit 01 is mapped to f1, bit 10 is mapped to f2, and bit 11 is mapped to f3; for mapping rule 2, bit 00 is mapped to f1, bit 01 is mapped to f2, bit 10 is mapped to f3, and bit 11 is mapped to f0.
[0106] When information 1 and information 2 are identical, with both bits being 00, the transmitting device determines frequency 1 to be f0 based on mapping rule 1 and information 1, and determines frequency 2 to be f1 based on mapping rule 2 and information 2. When information 1 and information 2 are identical, with both bits being 0110110101, the transmitting device determines frequency 1 to be {f1, f2, f3, f1, f1} based on mapping rule 1 and information 1, and determines frequency 2 to be {f2, f3, f0, f2, f2} based on mapping rule 2 and information 2. When information 1 is bit 01 and information 2 is bit 10, the transmitting device determines frequency 1 to be {f1} based on mapping rule 1 and information 1, and determines frequency 2 to be {f3} based on mapping rule 2 and information 2.
[0107] As can be seen from the above, the transmitting device determines 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. Because the first mapping rule is different from the second mapping rule, the frequencies associated with the information can be randomized, preventing the same frequency from being reused, thereby obtaining greater frequency diversity gain, and effectively reducing the impact of channel quality on data transmission.
[0108] In the above content, the transmitting device needs to map the information to be transmitted 1 to the frequency to obtain a signal, and then send the signal to the receiving device, so that the receiving device can obtain the information to be transmitted 1. Therefore, the transmitting 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, signal 1 is sent to the receiving device; during the p-th period, signal 2 is sent to the receiving device.
[0111] Correspondingly, the receiving device receives signal 1 during the i-th time period and receives signal 2 during the p-th time period.
[0112] Specifically, since frequency 1 is different from frequency 2, the frequencies mapped to information in different time periods are different, avoiding the reuse of the same frequency, 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 thereto.
[0114] S430: The receiving device processes the information to be transmitted 1.
[0115] Specifically, the receiving device receives N signals in N time periods, not the original information. The receiving device needs to process the received signals to obtain the information to be transmitted 1.
[0116] Specifically, the receiving device receives signals at time segment i and time segment p, respectively, and demodulates information according to mapping rule 1 and mapping rule 2, respectively. During time segment i, detection determines that the activated frequency is frequency 1, and based on the activated frequency 1 and mapping rule 1, the transmitted information is demodulated to be information 1. During time segment p, detection determines that the activated frequency is frequency 2, and based on the activated frequency 2 and mapping rule 2, the transmitted information is demodulated to be information 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, and thus 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 uses FSK modulation as an example, and Figure 6 illustrates the technical solution described in Figure 5 . Figure 7 uses OOK modulation as an example, and Figure 8 illustrates the technical solution described in Figure 7 . It should be noted that both Figures 5 and 7 illustrate the example of a transmitting device repeatedly transmitting information 1 to be transmitted to a receiving device four times.
[0121] FIG5 is a schematic diagram of an interaction flow of a communication method 500 according to an embodiment of the present application. The method 500 includes:
[0122] S510: The transmitting 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 frequencies 1 to 4 can refer to a single frequency or a group of frequencies, without limitation.
[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.
[0124] Table 2
[0125] As shown in Table 2, illustratively, the transmitting device determines frequency 1 as {f0, f1, f2, f3} according to mapping rule 1 and information 1, and activates frequency 1 using FSK modulation to obtain signal 1. The transmitting device determines frequency 2 as {f1, f2, f3, f0} according to mapping rule 2 and information 2, and activates frequency 2 using FSK modulation to obtain signal 2. The transmitting device determines frequency 3 as {f2, f3, f0, f1} according to mapping rule 3 and information 3, and activates frequency 3 using FSK modulation to obtain signal 3. Correspondingly, the transmitting device determines frequency 4 as {f3, f0, f1, f2} according to mapping rule 4 and information 4, and activates frequency 4 using FSK modulation to obtain signal 4.
[0126] 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 .
[0127] 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.
[0128] During time period 1, the sending device uses mapping rule 1 to map the information and activation frequency, and obtains signal 1; during time period 2, the sending device uses mapping rule 2 to map the information and activation frequency, and obtains signal 2; during time period 3, the sending device uses mapping rule 3 to map the information and activation frequency, and obtains signal 3; during time period 4, the sending device uses mapping rule 4 to map the information and activation frequency, and obtains signal 4, see Figure 6 for details.
[0129] Figure 6 is a schematic diagram of a mapping relationship between information and frequency according to an embodiment of the present application. As shown in Figure 6, during time period 1, the transmitting device sequentially activates f0, f1, f2, and f3; during time period 2, the transmitting device sequentially activates f1, f2, f3, and f0; during time period 3, the transmitting device sequentially activates f2, f3, f0, and f1; and during time period 4, the transmitting device sequentially activates f3, f0, f1, and f2. For details on the activation method, refer to the aforementioned description of the FSK modulation method and will not be repeated here.
[0130] More specifically, during time period 1, the transmitting device sequentially activates f0, f1, f2, and f3 to transmit bits 00, 01, 10, and 11, respectively, thereby completing one transmission of the information to be transmitted 1. During time period 2, the transmitting device sequentially activates f1, f2, f3, and f0 to transmit bits 00, 01, 10, and 11, respectively, thereby completing two repeated transmissions of the information to be transmitted 1. During time period 3, the transmitting device sequentially activates f2, f3, f0, and f1 to transmit bits 00, 01, 10, and 11, respectively, thereby completing three repeated transmissions of the information to be transmitted 1. During time period 4, the transmitting device sequentially activates f3, f0, f1, and f2 to transmit bits 00, 01, 10, and 11, respectively, thereby completing four repeated transmissions of the information to be transmitted 1.
[0131] As can be seen from the preceding information, bit 00 is transmitted by activating f0, f1, f2, and f3, respectively; bit 01 is transmitted by activating f1, f2, f3, and f0, respectively; bit 10 is transmitted by activating f2, f3, f0, and f1, respectively; and bit 11 is transmitted by activating f3, f0, f1, and f2, respectively. If the channel quality corresponding to f0 is poor, the transmitting device can also transmit bits 00, 01, 10, and 11 to the receiving device by activating f1, f2, and f3. This effectively reduces the impact of channel quality on data transmission.
[0132] S530: The receiving device processes signal 1, signal 2, signal 3, and signal 4.
[0133] Specifically, the receiving device processes signals 1 to 4 to obtain information 1 to be transmitted.
[0134] 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, and thus effectively reducing the impact of channel quality on data transmission.
[0135] The above content describes the FSK modulation method as an example. The OOK modulation method is described below.
[0136] FIG7 is a schematic diagram of an interaction flow of a communication method 700 according to an embodiment of the present application. The method 700 includes:
[0137] S710. The transmitting device determines frequency 1 according to mapping rule 1 and information 1, and performs OOK modulation on information 1 at frequency 1 to obtain signal 1; determines frequency 2 according to mapping rule 2 and information 2, and performs OOK modulation on information 2 at frequency 2 to obtain signal 2; determines frequency 3 according to mapping rule 3 and information 3, and performs OOK modulation on information 3 at frequency 3 to obtain signal 3; and determines frequency 4 according to mapping rule 4 and information 4, and performs OOK modulation on information 4 at frequency 4 to obtain signal 4. Each of the above frequencies 1 to 4 can be used to refer to a single frequency or a group of frequencies, without limitation.
[0138] Specifically, to improve transmission efficiency, the transmitting device can use multiple channels to simultaneously transmit information 1. This description uses four parallel channels as an example. Each channel transmits two bits at a time, allowing the transmitting device to transmit eight bits simultaneously. For example, information 1 through information 4 are the bit sequence 00011011. For details, see Table 3.
[0139] Table 3
[0140] As shown in Table 3, illustratively, the transmitting device determines frequency 1 as {f0, f1, f2, f3} based on mapping rule 1 and information 1, and performs OOK modulation on information 1 on frequency 1 to obtain signal 1. The transmitting device determines frequency 2 as {f1, f2, f3, f0} based on mapping rule 2 and information 2, and performs OOK modulation on information 2 on frequency 2 to obtain signal 2. The transmitting device determines frequency 3 as {f2, f3, f0, f1} based on mapping rule 3 and information 3, and performs OOK modulation on information 3 on frequency 3 to obtain signal 3. The transmitting device determines frequency 4 as {f3, f0, f1, f2} based on mapping rule 4 and information 4, and performs OOK modulation on information 4 on frequency 4 to obtain signal 4. For details, please refer to Figure 8.
[0141] FIG8 is a schematic diagram of another mapping relationship between information and frequency in an embodiment of the present application. As shown in FIG8 , during time period 1, the transmitting device performs OOK modulation on the first and second bits of information 1 on f0 and transmits bit 00; performs OOK modulation on the third and fourth bits of information 1 on f1 and transmits bit 01; performs OOK modulation on the fifth and sixth bits of information 1 on f2 and transmits bit 10; performs OOK modulation on the seventh and eighth bits of information 1 on f3 and transmits bit 11. During time period 2, the transmitting device performs OOK modulation on the first and second bits of information 1 on f1 and transmits bit 00; performs OOK modulation on the third and fourth bits of information 1 on f2 and transmits bit 01; performs OOK modulation on the fifth and sixth bits of information 1 on f3 and transmits bit 10; performs OOK modulation on the seventh and eighth bits of information 1 on f0 and transmits bit 11. During time period 3, the transmitting device performs OOK modulation on the first and second bits of information 1 on f2 and transmits bit 00. It performs OOK modulation on the third and fourth bits of information 1 on f3 and transmits bit 01. It performs OOK modulation on the fifth and sixth bits of information 1 on f0 and transmits bit 10. It performs OOK modulation on the seventh and eighth bits of information 1 on f1 and transmits bit 11. During time period 4, the transmitting device performs OOK modulation on the first and second bits of information 1 on f3 and transmits bit 00. It performs OOK modulation on the third and fourth bits of information 1 on f0 and transmits bit 01. It performs OOK modulation on the fifth and sixth bits of information 1 on f1 and transmits bit 10. It performs OOK modulation on the seventh and eighth bits of information 1 on f2 and transmits bit 11.
[0142] More specifically, during time period 1, the transmitting device simultaneously transmits bits 00, 01, 10, and 11 via f0, f1, f2, and f3, thereby completing one transmission of the information to be transmitted 1. During time period 2, the transmitting device simultaneously transmits bits 00, 01, 10, and 11 via f1, f2, f3, and f0, thereby completing two repeated transmissions of the information to be transmitted 1. During time period 3, the transmitting device simultaneously transmits bits 00, 01, 10, and 11 via f2, f3, f0, and f1, thereby completing three repeated transmissions of the information to be transmitted 1. During time period 4, the transmitting device simultaneously transmits bits 00, 01, 10, and 11 via f3, f0, f1, and f2, thereby completing four repeated transmissions of the information to be transmitted 1.
[0143] As can be seen from the above, bit 00 is transmitted via f0, f1, f2, and f3; bit 01 is transmitted via f1, f2, f3, and f0; bit 10 is transmitted via f2, f3, f0, and f1; and bit 11 is transmitted via f3, f0, f1, and f2. If the channel quality corresponding to f0 is poor, the transmitting device can also transmit bits 00, 01, 10, and 11 to the receiving device via f1, f2, and f3. This effectively reduces the impact of channel quality on data transmission.
[0144] 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 .
[0145] 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.
[0146] S730: The receiving device processes signal 1, signal 2, signal 3, and signal 4.
[0147] Specifically, the receiving device processes signals 1 to 4 to obtain information 1 to be transmitted.
[0148] 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, and thus effectively reducing the impact of channel quality on data transmission.
[0149] It should be noted that methods 400, 500, and 700 primarily describe how a transmitting device uses different mapping rules to obtain different frequencies, thereby enabling information transmission via different frequencies, thereby effectively reducing the impact of channel quality on data transmission. In addition, embodiments of the present application also support obtaining different frequencies using other methods and the same mapping rules, thereby also enabling information transmission via different frequencies, thereby effectively reducing the impact of channel quality on data transmission.
[0150] In one possible implementation, the transmitting device scrambles information 1 using scrambling code sequence 1 to obtain scrambled information 1, and the transmitting 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 transmitting device determines frequency 1 based on mapping rule 1 and scrambled information 1, and further determines frequency 2 based on mapping rule 1 and scrambled information 2, where frequency 1 is different from frequency 2.
[0151] For example, when information 1 and information 2 are identical, both containing bits 00, the transmitting device applies the same mapping rule 1 to 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 to be f0 based on mapping rule 1 (see Table 1) and the scrambled information 1. The transmitting device performs a modulo-2 addition operation on information 2 and the scrambling sequence 01 to obtain 01, and determines frequency 2 to be f1 based on mapping rule 1 and the scrambled information 2. When information 1 and information 2 are identical, both containing the bit sequence 0110110101, the transmitting device applies the same mapping rule 1 to information 1 and information 2. However, before mapping, the transmitting device performs a modulo-2 addition operation on information 1 and the scrambling code sequence 0000000000 to obtain the scrambled information 1, which is 0110110101. Based on mapping rule 1 and the information 2 after the scrambling code is added, frequency 1 is determined to be {f1, f2, f3, f1, f1}. The transmitting device performs a modulo-2 addition operation on information 2 and the scrambling code sequence 1101111111 to obtain the scrambled information 2, which is 1011001010. Based on mapping rule 1 and the information 2 after the scrambling code is added, frequency 2 is determined to be {f2, f3, f0, f2, f2}.
[0152] 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 processing by the same mapping rule, the embodiment of the present application supports at least two time periods. Information transmitted is transmitted through different frequencies, which can effectively reduce the impact of channel quality on data transmission.
[0153] It should also be noted that the transmitting device can combine different mapping rules and scrambling schemes to transmit information 1 to the receiving device. For example, the transmitting device first scrambles information 1 and information 2, then uses mapping rules 1 and 2 to map the information to frequencies, respectively. Finally, the scrambled information is sent to the receiving device. This further ensures that information is transmitted using different frequencies, effectively reducing the impact of channel quality on data transmission.
[0154] In another possible implementation, the transmitting device performs a first cyclic shift on information 1 to obtain cyclically shifted information 1, and performs a second cyclic shift on information 2 to obtain cyclically shifted information 2, where the first cyclic shift is different from the second cyclic shift. The transmitting device determines frequency 1 based on mapping rule 1 and cyclically shifted information 1, and determines frequency 2 based on mapping rule 1 and cyclically shifted information 2, where frequency 1 is different from frequency 2.
[0155] Exemplarily, when information 1 and information 2 are the same, both are bit sequences 00011011, the transmitting device adopts 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 0-bit cyclic shift on information 1 (such as a first number of cyclic shifts), and the information 1 after cyclic shift is 00011011, and determines frequency 1 to be {f0, f1, f2, f3, f3} based on mapping rule 1 and the information 1 after cyclic shift; the transmitting device performs a 2-bit cyclic shift on information 2 (such as a second number of cyclic shifts), and the information 2 after cyclic shift is 01101100, and determines frequency 2 to be {f1, f2, f3, f0, f0} based on mapping rule 1 and the information 2 after cyclic shift.
[0156] 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 processing 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.
[0157] It should also be noted that the transmitting device can combine different mapping rules with cyclic shift processing, and then use mapping rule 1 and mapping rule 2 to map information to frequency, and finally send the information to the receiving device. This can further ensure that different frequencies are used to transmit information, effectively reducing the impact of channel quality on data transmission.
[0158] In addition, in the description of methods 400, 500, and 700 above, the transmitting device may also send configuration information 1 to the receiving device. Configuration information 1 is used to configure transmission parameters of information 1 to be transmitted. Configuration information 1 includes at least one of the following: number of transmissions, modulation method, modulation order, time interval, whether repeated transmission is used, information-to-frequency mapping rules, detection starting time slot and period, etc. This facilitates the receiving device to better receive information 1 to be transmitted.
[0159] Specifically, the configuration information 1 may be carried in a system information block (SIB) or in radio resource configuration information (RRC), without limitation.
[0160] In one possible implementation, the sending device sends configuration information 1 to the receiving device via unicast or broadcast, which is not limited.
[0161] In the above descriptions of methods 400, 500, and 700, each time period can be associated with a mapping rule. The transmitting device can also send the mapping rule associated with each time period to the receiving device, or the mapping rule associated with each time period can be predefined. This facilitates the receiving device to obtain the mapping relationship between information and frequency, and facilitates the receiving device to better obtain the information 1 to be transmitted.
[0162] In one possible implementation, the mapping relationship corresponding to each of the N time periods is different, so as to minimize the impact of channel quality on data transmission.
[0163] 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.
