Description

Technical Field

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

[0002] Wireless communications and radar detection are two of the most common and important applications of modern radio frequency (RF) technology. Communications are used to transmit information between devices, while radar is used to detect and identify targets. Traditionally, communications and radar have been independently developed and designed based on their respective functions and frequency bands, without interfering with each other.

[0003] With the advancement of RF technology, communications and radar are increasingly being designed jointly. This is primarily due to three factors: First, with the exponential growth of wireless devices and data traffic, spectrum resources are becoming increasingly scarce; second, radar can assist communications in achieving better performance, such as faster neighboring cell development and beamforming; and third, with the increasingly complex electromagnetic environment, the performance of individual radars is becoming increasingly limited, leading to a growing demand for multi-radar networking. Because communications and radar must meet the requirements of spectrum efficiency, performance, and multi-tasking, the design of Joint Communication and Radar (JCR) has attracted widespread attention.

[0004] Currently, the main approach to designing new waveforms for integrated communication radars is to use a joint waveform design that combines communication and radar functions. However, ensuring that the joint waveform can meet diverse needs is an urgent issue to be addressed. Summary of the Invention

As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0037] You should know that Figure 1 The terminal 11 and the network side device 12 can both be implemented as communication devices integrated with communication radars, which can not only transmit signals between devices, but also detect and identify targets.

[0038] The signal transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0039] like Figure 2 As shown, a signal transmission method according to an embodiment of the present application includes:

[0040] In step 201, a first communication device obtains priority information and waveform-related configuration information, wherein the priority information is used to indicate the priority of a communication performance constraint condition of a signal and / or the priority of a radar performance constraint condition of the signal, and the waveform-related configuration information is configuration information for determining a value of a waveform parameter.

[0041] In this step, by obtaining the priority information and the waveform-related configuration information, the two pieces of information can be used to collaboratively determine the values ​​of the waveform parameters.

[0042] Step 202: The first communication device determines a target value of a waveform parameter according to the priority information and the waveform-related configuration information.

[0043] In this step, the target value of the waveform parameter is determined based on the priority information and waveform-related configuration information obtained in step 201.

[0044] Step 203: The first communication device performs at least one of the following according to the target value:

[0045] Transmitting a signal in which the waveform parameter is the target value;

[0046] The target value is sent.

[0047] In this step, the first communication device can directly use the target value of the waveform parameter determined in step 202 to complete signal transmission, and / or send the target value to the target communication device to instruct the target communication device to transmit a signal with the waveform parameter being the target value.

[0048] In this way, the first communication device transmits a signal with a waveform parameter at a target value, and / or sends the target value to a target communication device, instructing the target communication device to transmit a signal with a waveform parameter at the target value. Because the target value is determined based on the acquired priority information (indicating the priority of the signal's communication performance constraints and / or the priority of the signal's radar performance constraints) and the waveform-related configuration information (used to determine the value of the waveform parameter), the waveform transmitting the signal not only achieves communication and radar integration, but also meets the signal's operating requirements, namely, whether communication performance or radar performance is prioritized.

[0049] The first communication device may be a core network device, a base station, or a terminal, and the target communication device may be a base station or a terminal. If the first communication device is a core network device, the target communication device may be a base station; if the first communication device is a base station, the target communication device may be a base station or a terminal; if the first communication device is a terminal, the target communication device may be a base station or a terminal.

[0050] The first communication device informs the target communication device (such as a terminal or network device) of the target value of the waveform parameter. If the first communication device is the transmitter of the signal, the target communication device can achieve more efficient reception after knowing the target value of the waveform parameter; if the first communication device is the receiver of the signal, the target communication device sends a signal with the waveform parameter as the target value based on the known target value of the waveform parameter, thereby ensuring the receiving performance of the first communication device.

[0051] Optionally, in this embodiment, in step 201, the first communication device acquiring priority information includes:

[0052] The first communication device receives priority information from the second communication device;

[0053] or,

[0054] The first communication device obtains performance requirement information and determines the priority information according to the performance requirement information, where the performance requirement information reflects the requirement for the communication performance or radar performance of the signal.

[0055] That is, the priority information may be determined and communicated by the second communication device to the first communication device, or may be determined autonomously by the first communication device. Optionally, the second communication device, like the first communication device, determines the priority information based on performance requirement information that can reflect requirements for signal communication performance or radar performance.

[0056] It should also be noted that, in this embodiment, the second communication device may be a third-party application, an application server, a core network device, or a base station. The second communication device may be a target communication device.

[0057] Additionally, optionally, the first communication device acquiring the performance requirement information includes:

[0058] The first communication device receives performance requirement information from the second communication device.

[0059] That is, the performance requirement information is sent by a third-party application, application server, core network device or base station. Of course, the performance requirement information can also indicate the target area detected by the radar or a designated target within the target area (ie, the radar detection object), as well as the communication object.

[0060] In addition, in this embodiment, optionally, in step 201, the first communication device acquiring waveform-related configuration information includes:

[0061] The first communication device receives waveform-related configuration information from the second communication device;

[0062] or,

[0063] The first communication device receives performance requirement information from the second communication device, and obtains the waveform-related configuration information according to the performance requirement information and an association relationship, the association relationship being an association relationship between the performance requirement information and the waveform-related configuration information.

[0064] That is, the waveform-related configuration information can be determined by the second communication device and informed to the first communication device, or can be autonomously determined by the first communication device.

[0065] The association relationship can be established based on capability information (related information of communication transmission capability and / or radar detection capability, such as maximum bandwidth of a transmitted signal, maximum power of a transmitted signal, supported subcarrier spacing configuration, etc.) of the communication device. Alternatively, the second communication device can determine the waveform-related configuration information based on the performance requirement information reflecting the requirement of communication performance or radar performance of a signal, and the association relationship between the performance requirement information and the waveform-related configuration information, together with the first communication device.

[0066] Therefore, taking the second communication device as a core network device, the first communication device obtains the waveform-related configuration information in the following ways:

[0067] 1) The first communication device reports its capability information to the core network device. After receiving the capability information of the first communication device, the core network device determines the waveform-related configuration information based on the performance requirement information and the association relationship, and configures the waveform-related configuration information to the first communication device;

[0068] 2) After receiving the performance requirement information from the core network device, the first communication device autonomously determines the waveform-related configuration information based on its capability information and the association relationship;

[0069] 3) The core network device determines first recommended information of the waveform-related configuration information based on the performance requirement information, and informs the first communication device of the first recommended information. Then, the first communication device autonomously determines the waveform-related configuration information based on its capability information and the first recommended information;

[0070] 4) After receiving the performance requirement information from the core network device, the first communication device autonomously determines second recommended information of the waveform-related configuration information based on its capability information and the performance requirement information, and informs the core network device of the second recommended information. Then, the core network device determines the waveform-related configuration information based on the second recommended information, and configures the waveform-related configuration information to the first communication device.

[0071] Of course, the core network device may only determine part of the waveform-related configuration information and configure the part of the waveform-related configuration information to the first communication device. The first communication device also needs to independently determine another part of the waveform-related configuration information.

[0072] Optionally, in this embodiment, the waveform-related configuration information includes at least one of the following:

[0073] Maximum bandwidth;

[0074] Maximum duty cycle;

[0075] Maximum multipath delay;

[0076] Maximum radial velocity of the communication receiver;

[0077] Maximum unambiguous distance;

[0078] Maximum unambiguous speed;

[0079] Maximum radial velocity of the radar detection object;

[0080] Minimum resolvable distance unit;

[0081] Minimum resolvable velocity unit;

[0082] Blind range.

[0083] Here, the maximum bandwidth B 0 It will affect the channel capacity of communication transmission and the ranging resolution of radar detection; the maximum duty cycle D 0 It is the ratio between the transmission pulse time length and the pulse period, which affects the channel capacity of communication transmission and the blind range of radar detection. The maximum multipath delay τ max It is the maximum time delay between each path of the communication receiver receiving the signal, which will affect the degree of inter-symbol interference; the maximum radial velocity v of the communication receiver cmax The Doppler effect of the moving communication object affects the subcarrier spacing of the communication receiver's received signal, which will affect the orthogonality between subcarriers; the maximum unambiguous distance R u 0 is the maximum target distance at which the radar can detect the target without ambiguity and correctly distinguish the target distance; the maximum unambiguous speed V u 0 It is the maximum target speed that the radar can detect without ambiguity and correctly distinguish the target speed; the maximum radial speed v of the radar detection object rmax The Doppler effect of the moving radar detection target affects the subcarrier spacing of the radar echo signal, which will affect the orthogonality between subcarriers; the minimum resolvable distance unit ΔR 0 It is the minimum distance between two targets that radar detection can distinguish in the radial distance dimension; the minimum resolvable velocity unit ΔV 0It is the minimum speed difference between two targets that radar detection can distinguish in the speed dimension; blind range R bz 0 This is because the target is close to the radar, and the leading edge of the target pulse echo returns to the radar before the trailing edge of the radar transmit pulse ends. As a result, the radar with a common transmitting and receiving antenna cannot receive the target echo at the maximum target distance.

[0084] After the first communication device acquires the performance requirement information, optionally, the first communication device determines the priority information according to the performance requirement information, including:

[0085] When the performance requirement information indicates that the performance requirement of the signal is that communication performance is higher than radar performance, determining that the priority of the communication performance constraint condition is higher than the priority of the radar performance constraint condition; or

[0086] When the performance requirement information indicates that the performance requirement of the signal is that radar performance is higher than communication performance, it is determined that the priority of the radar performance constraint condition is higher than the priority of the communication performance constraint condition.

[0087] That is to say, if the communication performance required by the signal is higher than the radar performance, that is, the communication radar integrated waveform is based on maximizing communication performance as the main focus and radar detection as the auxiliary focus, then the priority information indicating that the priority of the communication performance constraint of the signal is greater than the priority of the radar performance constraint of the signal can be determined; if the radar performance required by the signal is higher than the communication performance, that is, the communication radar integrated waveform is based on maximizing radar detection performance as the main focus and communication transmission as the auxiliary focus, then it can be determined that the priority of the radar performance constraint is greater than the priority of the communication performance constraint.

[0088] It should be understood that for communication performance, relevant parameters include:

[0089] 1) Channel capacity

[0090] For an AWGN-dominated channel, the channel capacity C is: Where α is the transmission loss coefficient, P t is the transmit power, N0 is the AWGN noise power spectral density, D is the duty cycle; B is the signal bandwidth.

[0091] 2) Doppler tolerance

[0092] The Doppler shift between a communication receiver and a transmitter is: Among them, v c is the radial velocity of the communication receiving end relative to the transmitting end, λ is the wavelength, c is the speed of light, and f c is the carrier frequency. In order to correctly demodulate the information, the received signal subcarriers must be orthogonal, that is, the maximum Doppler frequency shift of the communication is far from f dc,maxLess than the subcarrier spacing Δf, satisfying: Δf ≥ 10f dc,max ; Here, 10 is the preset subcarrier spacing setting parameter.

[0093] 3) Guard interval length

[0094] To eliminate intersymbol interference, the length of the guard interval (CP) must be no less than the maximum multipath delay of the communication channel: T g ≥τ max ; Among them, T g is the OFDM symbol guard interval, τ max is the maximum multipath delay of the communication channel.

[0095] For radar performance, relevant parameters include:

[0096] 1) Doppler tolerance

[0097] The Doppler frequency shift f caused by the radial velocity of the target and the radar dr for: Among them, v r is the radial velocity of the target relative to the radar. In order to maintain the orthogonality between the subcarriers of the OFDM waveform, the maximum Doppler frequency shift f dr,max It must be much smaller than the subcarrier spacing Δf, satisfying: Δf ≥ 10f dr,max ; Here, 10 is the preset subcarrier spacing setting parameter.

[0098] 2) Maximum Unambiguous Velocity (MUV) and Maximum Unambiguous Range (MUR)

[0099] MUV and MUR are related to the pulse repetition frequency (PRF), the maximum unambiguous velocity V u for: Maximum unambiguous distance R u for: Among them, the pulse repetition period T r =1 / f r .

[0100] 3) Distance resolution

[0101] The range resolution ΔR depends only on the signal bandwidth: Among them, N c is the number of subcarriers.

[0102] 4) Speed ​​resolution

[0103] The velocity resolution ΔV depends on the pulse repetition frequency fr and the number of pulses N within the radar coherent processing interval (CPI) r :

[0104] 5) Blind range

[0105] Blind range R bz Depends on the pulse width T p :

[0106] It can be seen that among the waveform parameters that affect signal performance, the independent parameters are shown in Table 1:

[0107] Table 1

[0108]

[0109] The other parameters are shown in Table 2 and can be derived from the independent parameters or do not constrain the waveform design:

[0110] Table 2

[0111]

[0112] Thus, in the embodiment of the present application, optionally, the waveform parameter includes at least one of the following:

[0113] OFDM symbol guard interval, subcarrier spacing, number of subcarriers, number of OFDM symbols in one pulse and pulse repetition frequency.

[0114] That is, the target value determined in step 202 corresponds to the parameter T g ,Δf,N c , N s , f r Of course, the values ​​of other parameters can be determined by T g ,Δf,N c , N s , f r The target value is further derived.

[0115] On the one hand, in this embodiment, the signal is transmitted using a communication-dominated communication-radar integrated waveform. Therefore, optionally, when the priority information indicates that the priority of the communication performance constraint condition is greater than the priority of the radar performance constraint condition, the communication performance constraint condition includes at least one of the following:

[0116] First constraint:

[0117] The second constraint:

[0118] The third constraint:

[0119] The fourth constraint:

[0120] The radar performance constraint condition includes at least one of the following:

[0121] The fifth constraint:

[0122] The sixth constraint:

[0123] Seventh constraint;

[0124] The eighth constraint:

[0125] Among them, the first constraint condition is T g ≥τ max , where T g is the OFDM symbol guard interval, τ max is the maximum multipath delay;

[0126] The second constraint condition is Δf ≥ f max , where Δf is the subcarrier spacing, f max is the maximum Doppler shift;

[0127] The third constraint condition is N c Δf≤B 0 , where N c is the number of subcarriers, B 0 is the configured maximum bandwidth;

[0128] The fourth constraint condition is where N s is the number of OFDM symbols in a pulse, f r is the pulse repetition frequency, D 0 is the maximum duty cycle configured;

[0129] The fifth constraint condition is Where c is the speed of light, is the configured maximum unambiguous distance;

[0130] The sixth constraint condition is where f c is the carrier frequency, is the maximum unambiguous speed of the configuration;

[0131] The seventh constraint condition is where ΔR 0 is the minimum resolvable distance unit configured;

[0132] The eighth constraint condition is where R bz 0 is the configured blind range.

[0133] That is to say, for the communication-dominated communication radar integrated waveform, the communication performance constraints of its waveform parameters include one or more of the first constraint, the second constraint, the third constraint and the fourth constraint; the radar performance constraints include one or more of the fifth constraint, the sixth constraint, the seventh constraint and the eighth constraint.

[0134] Moreover, since communication is currently the dominant factor, the second constraint f max Take a specific multiple of the maximum Doppler frequency shift f of the communication dc,max , that is, Δf ≥ ωf dc,max , indicating that Δf is much larger than f dc,max , ω is an adjustable subcarrier spacing setting parameter, such as ω is equal to 10.

[0135] Among them, if the above-mentioned communication performance constraints include the first constraint, the second constraint, the third constraint and the fourth constraint, and the radar performance constraints include the fifth constraint, the sixth constraint, the seventh constraint and the eighth constraint, optionally, the priority information indicates that the priority order of the constraints is from high to low: the third constraint, the fourth constraint, the first constraint, the second constraint, the eighth constraint, the fifth constraint, the sixth constraint, and the seventh constraint.

[0136] At this time, the priority information indicates the priority of the constraints under communication dominance as shown in Table 3 below:

[0137] Table 3

[0138]

[0139] Among them, the smaller the priority value, the higher the priority. For example, the third constraint condition with a priority value of 1 is the constraint condition with the highest priority, and the seventh constraint condition with a priority value of 8 is the constraint condition with the lowest priority.

[0140] Optionally, in this embodiment, step 202 includes:

[0141] The first communication device determines, based on the waveform-related configuration information and the priority information indicating that the priority of the communication performance constraint is greater than the priority of the radar performance constraint, candidate values ​​of the waveform parameters, wherein the candidate values ​​satisfy the communication performance constraint;

[0142] In a case where the candidate values ​​all satisfy or maximize the satisfaction of the radar performance constraint condition, the first communication device determines the candidate value as the target value of the waveform parameter; or

[0143] The radar performance constraints include the fifth constraint and the sixth constraint. If the candidate value does not satisfy the fifth constraint or the sixth constraint, the first communication device updates the candidate value until the candidate value satisfies the fifth constraint and the sixth constraint, and determines the candidate value that satisfies the fifth constraint and the sixth constraint as the target value of the waveform parameter.

[0144] In this way, the first communication device will first determine a candidate value of the waveform parameter that can meet the communication performance constraint based on the acquired waveform-related configuration information and the priority information indicating that the priority of the communication performance constraint is greater than the priority of the radar performance constraint. Afterwards, if the candidate value can fully meet or maximize the satisfaction of the radar performance constraint, then the candidate value is the target value. Here, based on the limitations of the communication performance constraint, there are cases where the candidate value cannot meet the radar performance constraint. However, because the current signal requires communication as the main factor and radar as the auxiliary factor, the candidate value can also be determined as the target value when it maximizes the satisfaction of the radar performance constraint. Maximizing satisfaction can also be understood as minimizing deviation, that is, the absolute difference between the candidate value and the reference value limited by the radar performance constraint compared to other values ​​is the smallest.

[0145] Alternatively, for a candidate value that satisfies the communication performance constraint, when the radar performance constraint includes a fifth constraint and a sixth constraint, and the candidate value does not satisfy the fifth constraint or the sixth constraint, the first communication device updates the candidate value until the candidate value satisfies the fifth constraint and the sixth constraint, and determines the candidate value that satisfies the fifth constraint and the sixth constraint as the target value of the waveform parameter.

[0146] On the other hand, in this embodiment, the transmission signal is a radar-dominated communication-radar integrated waveform. Therefore, optionally, when the radar performance is higher than the communication performance, the communication performance constraint condition includes at least one of the following:

[0147] First constraint:

[0148] The fourth constraint:

[0149] The radar performance constraint condition includes at least one of the following:

[0150] The second constraint:

[0151] The third constraint:

[0152] Seventh constraint;

[0153] The eighth constraint:

[0154] Among them, the first constraint condition is T g ≥τmax , where T g is the OFDM symbol guard interval, τ max is the maximum multipath delay;

[0155] The second constraint condition is Δf ≥ f max , where Δf is the subcarrier spacing, f max is the maximum Doppler shift;

[0156] The third constraint condition is N c Δf≤B 0 , where N c is the number of subcarriers, B 0 is the configured maximum bandwidth;

[0157] The fourth constraint condition is where N s is the number of OFDM symbols in a pulse, f r is the pulse repetition frequency, D 0 is the maximum duty cycle configured;

[0158] The seventh constraint condition is where ΔR 0 is the minimum resolvable distance unit configured;

[0159] The eighth constraint condition is where R bz 0 is the configured blind range.

[0160] That is to say, for the communication-dominated communication radar integrated waveform, the communication performance constraints of its waveform parameters include one or more of the first constraint and the fourth constraint; the radar performance constraints include one or more of the second constraint, the third constraint, the seventh constraint and the eighth constraint.

[0161] Moreover, since radar is currently the dominant factor, the second constraint f max Take a specific multiple of the radar's maximum Doppler frequency shift f dr,max , that is, Δf ≥ ωf dr,max , indicating that Δf is much larger than f dr,max , ω is an adjustable subcarrier spacing setting parameter, such as ω is equal to 10.

[0162] Among them, if the above-mentioned communication performance constraints include the first constraint and the fourth constraint, and the radar performance constraints include the second constraint, the third constraint, the seventh constraint and the eighth constraint, optionally, the priority information indicates that the priority order of the constraints is from high to low: the eighth constraint, the second constraint, the seventh constraint, the third constraint, the fourth constraint, and the first constraint.

[0163] At this time, the priority information indicates that the priority of the constraint condition under the radar dominance is as shown in Table 4:

[0164] Table 4

[0165]

[0166] Here, as in Table 3, the smaller the value of the priority, the higher the priority, and the eighth constraint condition with a priority value of 1 is the constraint condition with the highest priority, and the first constraint condition with a priority value of 6 is the constraint condition with the lowest priority.

[0167] Optionally, in this embodiment, step 202 comprises:

[0168] The first communication device determines a candidate value of the waveform parameter according to the waveform-related configuration information and the priority information indicating that the priority of the radar performance constraint condition is higher than the priority of the communication performance constraint condition, wherein the candidate value satisfies the communication performance constraint condition and the radar performance constraint condition;

[0169] The first communication device determines whether the candidate value satisfies a fifth constraint condition and a sixth constraint condition;

[0170] In the case where the candidate value satisfies the fifth constraint condition and the sixth constraint condition, the first communication device takes the candidate value as the target value; or

[0171] In the case where the candidate value does not satisfy the fifth constraint condition or the sixth constraint condition, the first communication device updates the candidate value until the candidate value satisfies the fifth constraint condition and the sixth constraint condition, and determines the candidate value satisfying the fifth constraint condition and the sixth constraint condition as the target value of the waveform parameter;

[0172] The fifth constraint condition is where c is the speed of light, is the configured maximum unambiguous distance;

[0173] The sixth constraint condition is where f c is the carrier frequency, is the configured maximum unambiguous velocity.

[0174] Different from candidate value determination when communication is dominant, here, the first communication device first determines a candidate value for the waveform parameter that satisfies the communication performance constraint and the communication performance constraint based on the acquired waveform configuration information and the priority information indicating that the radar performance constraint has a higher priority than the communication performance constraint. Next, based on the fifth and sixth constraints, it determines whether the determined candidate value satisfies both. If both constraints are met, the candidate value becomes the target value. If one or both constraints are not met, the candidate value is updated until it satisfies both constraints, at which point it is adopted as the target value.

[0175] It should be noted that in this embodiment, regardless of whether the priority of the communication performance constraint is higher than the priority of the radar performance constraint, or whether the priority of the radar performance constraint is higher than the priority of the communication performance constraint, the same method, such as updating the candidate value with a staggered repetition rate, can be used when updating the candidate value. Therefore, optionally, the first communication device updates the candidate value, including:

[0176] The first communication device obtains at least two subcarrier spacings in total by setting the subcarrier spacing parameter adjusted at least once and the candidate value;

[0177] The first communication device determines at least two pulse repetition frequencies corresponding to the at least two subcarrier spacings;

[0178] The first communication device determines a maximum unambiguous distance and a maximum unambiguous speed of the staggered pulse repetition frequencies according to the at least two pulse repetition frequencies;

[0179] The maximum unambiguous distance corresponding to the staggered repetition frequency is greater than or equal to And the maximum unambiguous speed of the staggered repetition frequency is greater than or equal to The first communication device updates the candidate value based on the at least two subcarrier spacings; or

[0180] The maximum unambiguous distance corresponding to the staggered repetition frequency is less than Or the maximum unambiguous speed of the staggered repetition frequency is less than The first communication device readjusts the subcarrier spacing setting parameters until the maximum unambiguous distance of the staggered repetition frequency is greater than or equal to And the maximum unambiguous speed of the staggered repetition frequency is greater than or equal to

[0181] Here, the subcarrier spacing setting parameter is a parameter for determining the subcarrier spacing Δf, and after adjusting the subcarrier spacing setting parameter, the candidate value of Δf will change. In this way, the subcarrier spacing setting parameter adjusted at least once by the first communication device can obtain at least two subcarrier spacings based on the subcarrier spacing setting parameter before and after adjustment, and accordingly, at least two corresponding pulse repetition frequencies can be determined. Then, the maximum unambiguous range and the maximum unambiguous speed of the staggered repetition frequency are determined according to the at least two pulse repetition frequencies, so as to complete the candidate value update. That is, when the determined maximum unambiguous range of the staggered repetition frequency is greater than or equal to and the determined maximum unambiguous speed of the staggered repetition frequency is greater than or equal to The candidate value can be updated based on the at least two pulse repetition frequencies; when the determined maximum unambiguous range of the staggered repetition frequency is less than or the determined maximum unambiguous speed of the staggered repetition frequency is less than It can be known that this adjustment is not successful, and the subcarrier spacing setting parameter needs to be adjusted again until the maximum unambiguous range of the corresponding staggered repetition frequency after adjustment is greater than or equal to and the maximum unambiguous speed of the staggered repetition frequency is greater than or equal to

[0182] Among them, two pulse repetition frequencies are used to illustrate the specific implementation of determining the maximum unambiguous range and the maximum unambiguous speed of the staggered repetition frequency according to the at least two pulse repetition frequencies:

[0183] Suppose that Δf1 and Δf2 are obtained after adjusting the subcarrier spacing setting parameter twice. And the corresponding f r1 is obtained by Δf1, the corresponding f r2 is obtained by Δf2, and m, n and Δf r1 are determined through f r =mΔf r2 and f r =nΔf r , where m and n are relatively prime, Δf r is the greatest common divisor of f r1 and f r2 , and the MUV of the staggered repetition frequency is expanded to PRF f r1 '=mnΔf r , and the corresponding value is recorded as MUV'. Similarly, the corresponding T r1 is obtained by Δf1, the corresponding T r2 is obtained by Δf2, and p, q and ΔT r1 are determined through T r =pΔT r2 and f r =qΔT r , where p and q are relatively prime, ΔT rThe maximum common divisor of T r1 and T r2 is T r1 , then the MUR of the staggered double frequency is expanded to the PRI of T r ' = p q ΔT 0 , and the corresponding value is denoted as MUR'.

[0184] Of course, only the implementation of the staggered double frequency is described here, and the staggered triple frequency is also applicable to the embodiments of the present application, and will not be described here.

[0185] In addition, the process of updating the candidate value can also use a genetic algorithm, which will not be described here.

[0186] The application of the embodiments of the present application will be described below in combination with specific scenarios:

[0187] Scenario one, the user equipment 1 (first communication device) receives performance requirement information from the base station (second communication device) belonging to it, which indicates that the performance requirement of the signal is that the communication performance is higher than the radar performance, that is, the maximum communication performance is given priority, and the radar detection is supplemented. The user equipment 1 also receives the waveform related configuration information configured by the RRC from the base station belonging to it. According to the received performance requirement information, the user equipment 1 can determine that the priority of the communication performance constraint condition is higher than that of the radar performance constraint condition (wherein the communication performance constraint condition includes the first constraint condition, the second constraint condition, the third constraint condition and the fourth constraint condition, and the radar performance constraint condition includes the fifth constraint condition, the sixth constraint condition, the seventh constraint condition and the eighth constraint condition), and knows that the priority order of the constraint condition is in turn from high to low: the third constraint condition, the fourth constraint condition, the first constraint condition, the second constraint condition, the eighth constraint condition, the fifth constraint condition, the sixth constraint condition and the seventh constraint condition. Then:

[0188] First, in order to maximize the communication channel capacity, according to the third constraint condition, the signal bandwidth is set to the maximum value B 0 in the system allowed range. c Δf = B 0 (1). According to the fourth constraint condition, the duty cycle is set to the maximum value D 0 in the system allowed range. s f r (T g +1 / Δf) = D 0 (2). At this time, the seventh constraint condition follows the fourth constraint condition.

[0189] Then, in order to take into account the radar performance, according to the first constraint condition, T g is minimized, and T g = τ maxIn order to take into account the radar performance, according to the second constraint, Δf = 10f dc,max , where 10 is the subcarrier spacing setting parameter, which is a pre-set and adjustable parameter. Correspondingly, it can be seen that the OFDM basic symbol length T = 1 / 10f dc,max Therefore, according to the above formula (1), we can get Correspondingly, we can know the OFDM symbol length T s =T g +1 / Δf=τ max +1 / 10f dc,max .

[0190] Then, according to the eighth constraint, the known T s =τ max +1 / 10f dc,max , compared with T s , 0.5×2R bz 0 / c,2R bz 0 / c size:

[0191] 1) If T s ≥2R bz 0 / c, the eighth constraint cannot be satisfied. In order to minimize the deviation from the eighth constraint, N s Take the minimum value, N s =1, no guard interval between OFDM symbols is required, then T g =0. Correspondingly, the pulse width T P and T S are equal to 1 / 10f dc,max . Further, through the above formula (2) we have f r =D 0 / T p At this point, the waveform parameter T g ,Δf,N c , N s and f r A candidate value has been obtained. At this time, if the candidate value satisfies the fifth and sixth constraints, the candidate value is the target value; if the candidate value does not satisfy at least one of the fifth and sixth constraints, the candidate value is updated (the specific updating method is as described above and will not be repeated here).

[0192] 2) If 0.5×2R bz 0 / c <T s <2R bz 0 / c, then the eighth constraint condition is satisfied. At this time, N s=1, no guard interval between OFDM symbols is required, then T g = 0. Correspondingly, T P and T S are equal to 1 / 10f dc,max . Further, through the above formula (2) we have f r =D 0 / T p At this point, the waveform parameter T g ,Δf,N c , N s and f r A candidate value has been obtained. At this time, if the candidate value satisfies the fifth and sixth constraints, the candidate value is the target value; if the candidate value does not satisfy at least one of the fifth and sixth constraints, the candidate value is updated (the specific updating method is as described above and will not be repeated here).

[0193] 3) If Ts≤0.5×2R bz 0 / c, then the eighth constraint condition is satisfied. At this time, T P =N s T s . Further, through the above formula (2) we have f r =D 0 / T p At this point, the waveform parameter T g ,Δf,N c , N s and f r A candidate value has been obtained. At this time, if the candidate value satisfies the fifth and sixth constraints, the candidate value is the target value; if the candidate value does not satisfy at least one of the fifth and sixth constraints, the candidate value is updated (the specific updating method is as described above and will not be repeated here).

[0194] Specifically, the content of the waveform-related configuration information is shown in Table 5 below:

[0195] Table 5

[0196]

[0197] Based on the waveform configuration information according to the above content, first obtain N by the third constraint condition c Δf=4×10 8 , according to the fourth constraint, N s f r (T g +1 / Δf)=0.2. According to the first constraint, we can get T g =τ max =0.1 / μs, from the second constraint condition we get Correspondingly, T = 1 / Δf = 7.143μs, T s =τ max +1 / Δf=7.243μs. So T s >2R bz 0 / c, the eighth constraint cannot be satisfied. Therefore, in order to minimize the deviation from the eighth constraint, N s =1, T g =0, with T p =T s =7.143μs. At this time, R bz =T p c / 2≈1.072km. Further, f r =D 0 / T p =28kHz. At this time, MUR = 5.36km, MUV = 14kHz. Obviously, both the fifth and sixth constraints are met. Therefore, the target values ​​of the waveform parameters are shown in Table 6:

[0198] Table 6

[0199] parameter <![CDATA[T g ]]> Δf <![CDATA[N c ]]> [0002N s ]]> <![CDATA[f r ]]> Value 0 140kHz 2857 1 28kHz

[0200] Scenario 2: User device 2 (first communication device) receives performance requirement information from its base station (second communication device), which indicates that the performance requirement of the signal is that radar performance is higher than communication performance, that is, the main focus is on maximizing radar detection performance, supplemented by communication transmission. User device 2 also receives waveform-related configuration information configured by RRC from its base station. Based on the received performance requirement information, user device 2 can determine that the priority of the radar performance constraint is greater than the priority of the communication performance constraint (wherein the communication performance constraint includes the first constraint and the fourth constraint, and the radar performance constraint includes the second constraint, the third constraint, the seventh constraint, and the eighth constraint), and learns that the priority order of the constraints is from high to low: the eighth constraint, the second constraint, the seventh constraint, the third constraint, the fourth constraint, and the first constraint. Then:

[0201] First, considering that the target distance is relatively close in the cellular communication scenario, the first priority of radar detection is blind range. At the same time, considering that the value of blind range will cause a large preset of other parameters, therefore, according to the eighth constraint, there is a formula

[0202] Then, in order to maintain the orthogonality between subcarriers and ensure that the target echo signal can be correctly demodulated, under the condition of satisfying the eighth constraint, according to the second constraint, there is therefore, Next, in order to improve the ranging resolution, while the signal bandwidth is limited by the system resource allocation, according to the seventh constraint and the third constraint, it can be known that N c Δf=B 0 , at this time there is Next, to maximize the communication channel capacity, we need to maximize the duty cycle under the radar performance parameter constraints. According to the fourth constraint, the maximum value of the duty cycle is:

[0203] Afterwards, in order to reduce inter-symbol interference, the OFDM symbol guard interval should meet the first constraint. s , 0.5×2R bz 0 / c,2R bz 0 / c size:

[0204] 1) If the OFDM basic symbol length T ≥ 2R bz 0 / c, then to satisfy the first constraint, T g The value of cannot meet the maximum multipath delay requirement, and communication must have inter-symbol interference. s =1, no guard interval between OFDM symbols is required, T g =0. Correspondingly, the value of PRF is: f r =Δf×D 0 .

[0205] 2) If 0.5×2R bz 0 / c <T<2R bz 0 / c, then the first constraint condition is satisfied, N s =1, no guard interval between OFDM symbols is required, T g =0. Correspondingly, the value of PRF is: f r =Δf×D 0 .

[0206] 3) If T≤0.5×2R bz 0 / c, then the first constraint is satisfied. At this time, T g =τ max , Correspondingly, the value of PRF is:

[0207] Finally, judge the obtained f rWhether the fifth and sixth constraints are satisfied. At this time, if the fifth and sixth constraints are satisfied, the candidate values ​​of each waveform parameter are the target values; if at least one of the fifth and sixth constraints is not satisfied, the candidate values ​​are updated (the specific updating method is as described above and will not be repeated here).

[0208] Specifically, the content of the waveform-related configuration information is as shown in Table 5. Based on the waveform-related configuration information and the above content, first, according to the eighth constraint condition, we get T p =N s (T g +1 / Δf)≤0.667μs; from the second constraint condition, we get From the third constraint, we get From the fourth constraint, we get D = D 0 = 0.2. According to the value of Δf, T = 1 / Δf = 0.667μs. Therefore, T = 2R bz 0 / c, then take N s =1, no guard interval between OFDM symbols is required, T g =0. Correspondingly, the value of PRF is: f r =Δf×D 0 =300kHz. At this time, since MUR=0.5km, MUV=150kHz, the sixth constraint condition is satisfied but the second constraint condition is not satisfied, and the updated candidate value is adopted.

[0209] Here, using staggered triple frequency, in the acquired Δf = 1.5MHz, return to adjust the value of Δf, and get the second repetition frequency: Δf = 2MHz, accordingly, get N c '=200, D'=0.2, T=1 / Δf=0.5μs, N s =1, T g =0,f r '=400kHz, then MUR'=0.4km; third frequency: Δf=2.5MHz, accordingly, we get N c '=160, D'=0.2, T=1 / Δf=0.4μs, N s =1, T g =0,f r '=500kHz, at this time MUR"=0.3km. After triple frequency deviation, MUR3=6km, which meets the fifth constraint condition and the target values ​​of the waveform parameters are determined. Therefore, the target values ​​of the waveform parameters are shown in Table 7:

[0210] Table 7

[0211] parameter <![CDATA[T g ]]> Δf <![CDATA[N c ]]> <![CDATA[N s ]]> <![CDATA[f r ]]> Repeat frequency 1 0 1.5MHz 266 1 300kHz Repeat 2 0 2MHz 200 1 400kHz Repeat frequency three 0 2.5MHz 160 1 500kHz

[0212] In summary, the method of the embodiment of the present application can determine the target values ​​of applicable waveform parameters based on the priority requirements of communication performance and radar performance of the signal transmitted by the integrated waveform of communication radar, complete the transmission of the signal, and take into account the dominant and auxiliary functions of the signal.

[0308] Those skilled in the art will understand that the terminal 500 may also include a power supply (such as a battery) to power each component, and the power supply may be logically connected to the processor 510 through a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system. Figure 5 The terminal structure shown in the figure does not constitute a limitation on the terminal. The terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently, which will not be repeated here.

[0309] It should be understood that in an embodiment of the present application, the input unit 504 may include a graphics processing unit (GPU) 5041 and a microphone 5042, and the graphics processor 5041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The display unit 506 may include a display panel 5061, and the display panel 5061 may be configured in the form of a liquid crystal display, an organic light emitting diode, etc. The user input unit 507 includes a touch panel 5071 and other input devices 5072.

[0310] In this embodiment of the present application, the radio frequency unit 501 receives downlink data from the network-side device and transmits it to the processor 510 for processing. Furthermore, the radio frequency unit 501 transmits uplink data to the network-side device. Typically, the radio frequency unit 501 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and the like.

[0311] The memory 509 can be used to store software programs or instructions and various data. The memory 509 may mainly include a program or instruction storage area and a data storage area, wherein the program or instruction storage area can store an operating system, at least one application program or instruction required for a function (such as a sound playback function, an image playback function, etc.). In addition, the memory 509 may include a high-speed random access memory and may also include a non-volatile memory, wherein the non-volatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory.

It is understood that the modem processor may not be integrated into processor 510.

[0313] The processor 510 is configured to obtain priority information and waveform-related configuration information, where the priority information is used to indicate the priority of a communication performance constraint condition of a signal and / or the priority of a radar performance constraint condition of the signal, and the waveform-related configuration information is configuration information used to determine a value of a waveform parameter.

[0316] The terminal transmits a signal with a waveform parameter at a target value, and / or sends the target value to a target communication device, instructing the target communication device to transmit a signal with a waveform parameter at the target value. Because the target value is determined based on acquired priority information (indicating the priority of the signal's communication performance constraints and / or the priority of the signal's radar performance constraints) and waveform-related configuration information (used to determine the value of the waveform parameter), the waveform transmitting the signal not only achieves communication and radar integration, but also meets the signal's operating requirements, namely, whether communication performance or radar performance is prioritized.
