Second, millimeter wave radar is controllable; the terminal equipment specifically has the control capability for the millimeter wave radar, and can be configured with control parameters when the millimeter wave radar works. Third, the network device has central regulation and control capability.
Fig. 2 is a flowchart of a millimeter wave radar communication method according to an embodiment of the present application. The method of the present embodiment is applied to a network device side, as shown in fig. 2, and the method of the present embodiment may include:
s101, a network device determines control parameters corresponding to S millimeter wave radars on N terminal devices respectively, wherein the control parameters of the S millimeter wave radars are not identical.
In the scheme, each of N terminal devices comprises at least one millimeter wave radar, and the network device can configure control parameters for S millimeter wave radars on the N terminal devices, so that unified scheduling of the control parameters of the S millimeter wave radars is realized. Wherein N, S are positive integers, it being understood that S is a positive integer greater than or equal to N.
In some possible cases, the control parameters of the millimeter wave radar include: one or a combination of operating frequency band, chirp time offset and time slot. It is understood that the operating frequency band, the chirp time offset, and the time slot are fixed parameters of the millimeter wave radar.
In other possible cases, the control parameters of the millimeter wave radar include: the chirp parameter may include one or a combination of a chirp initial phase, a chirp slope, a chirp start frequency, and a chirp idle time. It can be understood that the chirp parameter is an adjustable parameter of the millimeter wave radar.
In other possible cases, the control parameters of the millimeter wave radar may include at least one of the above-described operating frequency band, the chirp time offset, and the time slot, and at least one of the chirp parameters.
One possible implementation:
the network device may determine, according to the priority of the control parameters, control parameters corresponding to the S millimeter wave radars, respectively.
Here, the control parameters of the millimeter wave radar are described by taking the above-mentioned operating frequency band, chirp time offset, time slot and chirp parameters as examples. The priority of the fixed parameter may be higher than the priority of the adjustable parameter, that is, the priority of the operating frequency band, the priority of the chirp time offset and the priority of the time slot in the control parameter are higher than the priority of the chirp parameter; the working frequency band, the chirp time offset and the time slot can be not prioritized or configured, and the embodiment of the application does not limit the priority; the chirp initial phase, the chirp slope, the chirp starting frequency and the chirp idle time may be not prioritized, or may be configured with a priority order, which is not limited in the embodiments of the present application.
Illustratively, the priority of the control parameters may be as follows: the priority of the working frequency band is higher than the priority of the chirp time shift, the priority of the chirp time shift is higher than the priority of the time slot, the priority of the time slot is higher than the priority of the chirp parameter, the priority of the chirp slope is higher than the priority of the chirp starting frequency, the priority of the chirp starting frequency is higher than the priority of the chirp idle time, and then the network equipment can determine the control parameters respectively corresponding to the S millimeter wave radars according to the priority sequence.
Illustratively, an allocable bandwidth is first determined according to the available frequency bands of the respective millimeter wave radars, and an operating frequency band is allocated to each millimeter wave radar; in the same working frequency band, the chirp time of the millimeter wave radars can correspond to different time windows, wherein the time windows are chirp time offsets; in the same operating frequency band, the same chirp time window, and multiple millimeter wave radars can correspond to different time slots. And so on.
It should be noted that, the priority of the control parameters may be set in other manners, and is not limited to the above illustration, for example, the priority of the chirp time offset may be higher than the priority of the time slot, and the priority of the time slot is higher than the priority of the operating frequency band, that is, the network device may configure different chirp time offsets for multiple millimeter wave radars in the same operating frequency band, and if the control parameters of all millimeter wave radars are not successfully configured, then configure different time slots for the transmitting signals of multiple millimeter wave radars in the same operating frequency band and under the condition of the same chirp time offset; if the control parameters of all the millimeter wave radars are not successfully configured, the network device can configure the control parameters for the millimeter wave radars in the next working frequency band in the above manner.
In this step, the specific implementation manner of the control parameters of the S millimeter wave radars determined by the network device is not limited, but only the determined control parameters of the S millimeter wave radars are not completely the same.
S102, the network equipment respectively sends first information to N terminal equipment.
The network equipment indicates control parameters corresponding to the millimeter wave radars configured by the network equipment to the terminal equipment by respectively sending first information to the N terminal equipment, wherein the first information sent by the network equipment to each terminal equipment comprises the control parameters of the millimeter wave radars on the terminal equipment. That is, each terminal receives respective first information including control parameters for the millimeter wave radar on the own terminal device.
In practical application, if a terminal device includes a plurality of millimeter wave radars, the network device may indicate control parameters corresponding to the plurality of millimeter wave radars respectively through the same signaling, or the network device may also indicate control parameters corresponding to the plurality of millimeter wave radars respectively through the plurality of signaling.
In the application, the network device determines control parameters corresponding to S millimeter wave radars on N terminal devices respectively, and sends first information to the N terminal devices respectively. In the scheme, the network equipment has central scheduling capability, and can uniformly configure control parameters for a plurality of millimeter wave radars, so that the control parameters of the millimeter wave radars are not completely identical, and the interference among the millimeter wave radars is effectively reduced.
Fig. 3 is a flowchart of a millimeter-wave radar communication method according to another embodiment of the present application. As shown in fig. 3, the method of the present embodiment includes:
s201, the network equipment receives second information respectively sent by N terminal equipment, wherein each piece of second information comprises control capability information of at least one millimeter wave radar on the terminal equipment.
The control capability information is used to indicate control parameters supported by the millimeter wave radar. The control capability information of the millimeter wave radar sent by the terminal equipment to the network equipment can provide a basic basis for the network equipment to accurately schedule control parameters for a plurality of millimeter wave radars.
In some possible cases, the control capability information may include: one or a combination of available frequency band, chirp time, maximum measured distance, and duty cycle of the transmitted signal.
In other possible cases, the control capability information may include: one or a combination of chirp initiation phase, chirp slope, chirp initiation frequency and chirp idle time.
In other possible cases, the control capability information may include at least one of an available frequency band, a chirp time, a maximum measurement distance, and a duty cycle of a transmission signal, and at least one of a chirp initial phase, a chirp slope, a chirp start frequency, and a chirp idle time.
It should be noted that the control capability information may include the names of the above-mentioned parameters and the value ranges of the parameters. For example, the available frequency band is 4GHz, the chirp time is 100-150 microseconds, and other parameters are similar.
Optionally, the second information may further include an identifier of the millimeter wave radar, where the identifier of the millimeter wave radar may be an identity Identifier (ID) of the millimeter wave radar, and of course, the identifier of the millimeter wave radar may also be other identifiers of the millimeter wave radar, which only needs to be capable of uniquely identifying one millimeter wave radar. On the one hand, the network equipment can ensure that the correct control parameters of the millimeter wave radar are issued to the terminal equipment according to the corresponding relation between the identifiers of the terminal equipment and the millimeter wave radar; on the other hand, if the network device is configured with a millimeter wave radar related database, the network device may acquire more related information of the millimeter wave radar from the millimeter wave radar related database according to the identifier of the millimeter wave radar.
S202, the network equipment determines control parameters corresponding to S millimeter wave radars according to control capability information corresponding to the S millimeter wave radars on N terminal equipment and the priority of the control parameters, wherein the control parameters of the S millimeter wave radars are not identical.
Specifically, the network device determines control parameters respectively supported by the S millimeter wave radars according to control capability information respectively corresponding to the S millimeter wave radars, and determines control parameters respectively corresponding to the S millimeter wave radars according to priorities of the control parameters.
In this step, the control parameters are similar to those described in S102 in the embodiment shown in fig. 2, and are not repeated here.
Illustratively, the network device determines the control parameters respectively corresponding to the 3 millimeter wave radars according to the control capability information respectively corresponding to the 3 millimeter wave radars and the priority of the control parameters.
Firstly, the network device determines that the available frequency band which can be allocated is 4GHz according to the available frequency bands which respectively correspond to the 3 millimeter wave radars, and the working frequency band of the millimeter wave radars is 2GHz, so that the available frequency band of the 4GHz can be divided into 2GHz working frequency bands, that is, under the condition that other control parameters are the same, the millimeter wave radars 1 and 2 can respectively occupy one 2GHz working frequency band, and under the condition, the millimeter wave radars 1 and 2 can not interfere with each other.
Then, according to the priority order of the control parameters, in the same working frequency band, the chirp time offset of each millimeter wave radar can be configured to realize that a plurality of millimeter wave radars in the same working frequency band do not generate interference with each other, specifically, if it is determined that the working frequency band of the millimeter wave radar 3 is the same as that of the millimeter wave radar 1, the network device determines the transmitting time respectively corresponding to the millimeter wave radar 1 and the millimeter wave radar 3 according to the maximum measuring distance respectively corresponding to the millimeter wave radar 1 and the millimeter wave radar 3, and then determines the chirp time offset respectively corresponding to the millimeter wave radar 1 and the millimeter wave radar 3 according to the chirp time respectively corresponding to the millimeter wave radar 1 and the millimeter wave radar 3 and the transmitting time respectively corresponding to the millimeter wave radar 1 and the millimeter wave radar 3.
For example, the chirp times of the millimeter wave radar 1 and the millimeter wave radar 3 are each 100 microseconds, and the maximum measurement distances of the millimeter wave radar 1 and the millimeter wave radar 3 are each 150 meters. The network device determines that the emission time corresponding to each of the millimeter wave radar 1 and the millimeter wave radar 3 is 1 microsecond according to the maximum measurement distance of the millimeter wave radar 1 and the millimeter wave radar 3, and in the same working frequency band, the network device configures that at least 1 microsecond offset exists between the chirp time corresponding to each of the millimeter wave radar 1 and the millimeter wave radar 3, and if the chirp time offset of the millimeter wave radar 1 is determined to be 0, the chirp time offset of the millimeter wave radar 3 is greater than or equal to 1 microsecond.
In practical application, the number of millimeter wave radars may be more, and the control parameters of each millimeter wave radar may be determined sequentially by referring to the above manner.
S203, the network device respectively sends the first information to N terminal devices.
This step is similar to step S102 in the embodiment shown in fig. 2, and reference is made to the detailed description in the embodiment shown in fig. 2, which is not repeated here.
In this embodiment, N terminal devices respectively send control capability information of millimeter wave radars included in the N terminal devices to a network device, and the network device determines control parameters corresponding to S millimeter wave radars respectively according to the control capability information corresponding to S millimeter wave radars sent by the N terminal devices and priorities of the control parameters. In this embodiment, the network device determines that the control parameters corresponding to the S millimeter wave radars are not identical by using the capability of uniformly scheduling the control parameters, thereby effectively reducing interference between the millimeter wave radars.
In a specific embodiment, the communication system comprises 2 terminal devices, a vehicle 1 and a vehicle 2, respectively, wherein the vehicle 1 comprises a millimeter wave radar 1 and the vehicle 2 comprises a millimeter wave radar 2 and a millimeter wave radar 3. The communication system further comprises a network device, which is a server. Referring to fig. 4, the method of the present embodiment includes:

It should be noted that, on the basis of the embodiment shown in fig. 4, if the communication system includes a greater number of terminal devices and each terminal device includes at least one millimeter wave radar, the server may determine, in a similar manner, control parameters corresponding to each millimeter wave radar according to control capability information of each millimeter wave radar and priorities of the control parameters, so that the multiple millimeter wave radars do not interfere with each other.
Distributed type
It should be noted that, in a distributed implementation, at least the following conditions are required:
the first terminal equipment has communication capability; in this scheme, the terminal devices may communicate through a network device, for example, a base station, or may directly communicate with each other, that is, the terminal devices have D2D communication capability; second, millimeter wave radar is controllable; the terminal equipment specifically has the control capability for the millimeter wave radar, and can be configured with control parameters when the millimeter wave radar works.
Fig. 5 is a flowchart of a millimeter-wave radar communication method according to another embodiment of the present application. As shown in fig. 5, the method of the present embodiment may include:
s401, the first terminal device determines whether interference exists between the S first millimeter wave radars and the N second millimeter wave radars according to current control parameters respectively corresponding to the S first millimeter wave radars and current control parameters respectively corresponding to the N second millimeter wave radars.
The first terminal equipment comprises S first millimeter wave radars, wherein S is greater than or equal to 1; the M second terminal devices include N second millimeter wave radars, each second terminal device includes one or more second millimeter wave radars, M, N is greater than or equal to 1. If the current control parameters of the first millimeter wave radar are stored in the control unit of the millimeter wave radar, the first terminal equipment can acquire the current control parameters of S first millimeter wave radars by accessing the control unit of the millimeter wave radar; the first terminal equipment receives broadcast information sent by M second terminal equipment respectively, and current control parameters of N second millimeter wave radars are obtained.
Alternatively, the current control parameters may include: one or a combination of operating frequency band, chirp time, maximum measured distance, duty cycle of the transmitted signal, chirp time offset, time slot, chirp initiation phase, chirp slope, chirp initiation frequency, chirp idle time, and chirp initiation time.
Among the above control parameters, if any one of the two millimeter wave radars is different, it means that there is no interference between the two millimeter wave radars. For example, if the operating frequency bands of the two millimeter wave radars are different and the other parameters are the same, then the two millimeter wave radars have no interference. If the time required for the millimeter wave radar to transmit a transmitting signal to receive a reflected signal is determined according to the maximum measurement distance of each millimeter wave radar, the number of millimeter wave radars which can coexist in the same working frequency band is determined according to the chirp time of one of the millimeter wave radars, and if the number of the millimeter wave radars which can coexist in the same working frequency band is exceeded, interference exists between the millimeter wave radars. If the working frequency bands are the same and the chirp time is the same, determining whether interference exists between the millimeter wave radars according to the duty ratio of the transmitting signals of each millimeter wave radar and the time slot of the transmitting signals. In the above control parameters, if any one of the parameters is different, there is no interference between the millimeter wave radars.
And S402, if so, the first terminal equipment determines the control parameters corresponding to the S first millimeter waves respectively according to the current control parameters corresponding to the S first millimeter wave radars respectively and the current control parameters corresponding to the N second millimeter wave radars respectively.
If it is determined that interference exists between the S first millimeter wave radars and the N second millimeter wave radars, it is indicated that current control parameters of one or more of the S first millimeter wave radars and the N second millimeter wave radars need to be adjusted currently, so that the control parameters respectively corresponding to the S first millimeter wave radars are not identical to the control parameters respectively corresponding to the N second millimeter wave radars, and therefore interference does not exist between the S first millimeter wave radars and the N second millimeter wave radars.
A detailed implementation of how to determine the control parameters of the S first millimeter wave radars will be described later in detail through specific embodiments.
It should be noted that, if it is determined that there is no interference between the S first millimeter wave radars and the N second millimeter wave radars, in this case, the first terminal device may determine to keep the current control parameters of the S first millimeter wave radars unchanged, and no operation needs to be performed.
In this embodiment, the first terminal device determines whether interference exists between the S first millimeter wave radars and the N second millimeter wave radars according to current control parameters of the S first millimeter wave radars and current control parameters of the N second millimeter wave radars; if so, determining the control parameters of the S first millimeter wave radars according to the current control parameters of the S first millimeter wave radars and the current control parameters of the N second millimeter wave radars, so that the control parameters of the S first millimeter wave radars are not identical to the control parameters of the N second millimeter wave radars, and further reducing the mutual interference of the S first millimeter wave radars and the N second millimeter wave radars.
Fig. 6 is a flowchart of a millimeter-wave radar communication method according to another embodiment of the present application. Referring to fig. 6, S402 may include the following processes:
s501, the first terminal equipment determines the first interference number corresponding to each first millimeter wave radar according to the current control parameters corresponding to the S first millimeter wave radars and the current control parameters corresponding to the N second millimeter wave radars.
The first interference number is used for indicating the number of second millimeter wave radars interfering with the first millimeter wave radars.
In an actual communication system, if the terminal device includes 2 or more millimeter wave radars, the plurality of millimeter wave radars do not interfere with each other. Therefore, when determining the first interference number corresponding to a certain first millimeter wave radar, whether interference exists between other first millimeter wave radars and the first millimeter wave radar can be disregarded.
S502, the first terminal equipment receives second broadcast messages respectively sent by M second terminal equipment.
Each second broadcast message includes a second interference number corresponding to a second millimeter wave radar on the second terminal device, where the second interference number is used to indicate the number of other millimeter wave radars interfering with the second millimeter wave radar.
It should be noted that, since the locations of the terminal devices may be different and the terminal devices may have mobility, each second terminal device may determine the second interference number corresponding to the second millimeter wave radar according to the current control parameters of other millimeter wave radars included in the received broadcast messages, where the broadcast messages may be sent by other second terminal devices, may be sent by the first terminal device, or may be sent by other third terminal devices capable of communicating with the second terminal device. Thus, other millimeter wave radars that interfere with the second millimeter wave radar may include the first millimeter wave radar, may also include the second millimeter wave radar on other second terminal devices, and may also include the millimeter wave radar on a third terminal device.
S503, the first terminal equipment determines the control parameters corresponding to the S first millimeter wave radars according to the first interference number corresponding to the S millimeter wave radars respectively, the second interference number corresponding to the N second millimeter wave radars respectively, the current control parameters corresponding to the S first millimeter wave radars respectively and the current control parameters of the N second millimeter wave radars.
In step 503, two different cases are further described:
(1) The number of the first interference corresponding to the S first millimeter wave radars is equal to the number of the second interference corresponding to the N second millimeter wave radars:
first, the first interference number corresponding to the S first millimeter wave radars is equal to the second interference number corresponding to the N second millimeter wave radars, and the first terminal equipment sends a third broadcast message which is used for indicating the first terminal equipment to adjust the control parameters of the first millimeter wave radars and comprises a time stamp.
It should be noted that, in the present solution, the second terminal device determines that the second interference number corresponding to the second millimeter wave radar included in the second terminal device is equal to the interference number corresponding to the other millimeter wave radars obtained in the received second broadcast message, where the second terminal device sends a third broadcast message, and the third broadcast message sent by the second terminal device is used to instruct the second terminal device to adjust the control parameter of the second millimeter wave radar included in the second terminal device, and the third broadcast message includes a timestamp.
Then, if the first terminal device determines that the timestamp of the third broadcast message sent by the first terminal device is earliest, the first terminal device preferentially adjusts the control parameters of the first millimeter wave radar, and in addition, other second terminal devices can keep the control parameters of the second millimeter wave radar unchanged. The first terminal device may adjust the control parameters of one or more first millimeter wave radars in the S millimeter wave radars, or the first terminal device may also adjust the control parameters of all S millimeter wave radars, which is not limited in this embodiment of the present application, and when the first terminal device adjusts the control parameters of the first millimeter wave radars, it only needs to ensure that the adjusted control parameters corresponding to the S first millimeter wave radars are not identical, and the control parameters corresponding to the S first millimeter wave radars are not identical to the control parameters of the N second millimeter wave radars.
If the first terminal equipment determines that the timestamp of the third broadcast message sent by the first terminal equipment is not the earliest, the first terminal equipment keeps the control parameters of the current first millimeter wave radar unchanged, namely, does not execute any operation; and the second terminal device with the earliest time stamp of the third broadcast message adjusts the control parameters of the millimeter wave radar included by the second terminal device.
(2) The number of first interference corresponding to the S first millimeter wave radars is unequal to the number of second interference corresponding to the N second millimeter wave radars:
in a possible implementation manner, under the condition that the number of first interference corresponding to the S first millimeter wave radars is unequal to the number of second interference corresponding to the N second millimeter wave radars, the anti-interference capability of the millimeter wave radars can be improved by adjusting the control parameter of the millimeter wave radar with the largest interference number.
Specifically, if the S first millimeter wave radars include millimeter wave radars with the largest interference number, the first terminal device adjusts the control parameter of the first millimeter wave radar with the largest interference number according to the current control parameter corresponding to the S first millimeter wave radars and the current control parameter corresponding to the N second millimeter wave radars respectively, so that the control parameters of the first millimeter wave radars with the largest interference number are not identical to the control parameters of other first millimeter wave radars and the control parameters of the N second millimeter wave radars.
If the S first millimeter wave radars do not include the millimeter wave radar with the largest interference number, the first terminal device may keep control parameters corresponding to the S first millimeter wave radars unchanged. In this case, the control parameter of the millimeter wave radar with the maximum interference number can be adjusted by the second terminal device corresponding to the millimeter wave radar with the maximum interference number.
In this embodiment, the first terminal device and the second terminal device have equal identities in the communication system, so if the number of first interference corresponding to the S first millimeter wave radars is equal to the number of second interference corresponding to the N second millimeter wave radars, the control parameter of which terminal device performs adjustment of the millimeter wave radars can be determined by the timestamp; if the number of the first interference corresponding to the S first millimeter wave radars is not equal to the number of the second interference corresponding to the N second millimeter wave radars, the terminal device corresponding to the millimeter wave radar with the largest interference number can preferably adjust the control parameters of the millimeter wave radars. Through the negotiation mechanism between the terminal devices, the interference between the millimeter wave radars is reduced by the upper layer tissue negotiation of each millimeter wave radar, so that the interference between the millimeter wave radars is effectively reduced.
In a specific embodiment, the communication system comprises 2 terminal devices, a vehicle 1 and a vehicle 2, respectively, wherein the vehicle 1 comprises a millimeter wave radar 1 and the vehicle 2 comprises a millimeter wave radar 2 and a millimeter wave radar 3.
