Background

Both The fourth generation mobile communication technology (The 4th Generation Mobile Communication Technology,4G) and The fifth generation mobile communication technology (The 5th Generation Mobile Communication Technology,5G) employ a communication acknowledgement mechanism in radio transmission to ensure transmission reliability, i.e. The receiving end feeds back to The received information whether it is successfully received or not an acknowledgement message, for example, an acknowledgement character (Acknowledge Character, ACK) or a negative response (Negative Acknowledge, NACK), which is set in The medium access control (Media Access Control, MAC) layer, the radio link control (Radio Link Control, RLC) layer and The packet data convergence (Packet Data Convergence Protocol, PDCP) layer.

Detailed Description

For the purposes, technical solutions and advantages of the embodiments of the present application to be more apparent, the specific technical solutions of the present application will be described in further detail below with reference to the accompanying drawings in the embodiments of the present application. The following examples are illustrative of the present application, but are not intended to limit the scope of the present application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.

An embodiment of the present application provides a communication confirmation method, and fig. 1 is a schematic implementation flow diagram of the communication confirmation method provided in the embodiment of the present application, as shown in fig. 1, the method may include the following steps 101 to 103:

in step 101, the communication body transmits first data to the communication destination through at least one first subframe.

In some embodiments, the communication subject and the communication target may be any devices that each have wireless signal transceiving and processing capabilities. For example, the communication subject and the communication target may be a mobile phone, a tablet computer, a notebook computer, a wearable device, a personal computer, a television, a network device (e.g., a base station, a pseudolite, etc.), or the like. The communication subject and the communication target may be the same or different in device type.

In the scene that the communication main body and the communication target are terminal equipment, the communication main body and the communication target can perform information interaction in a short-distance communication mode such as millimeter wave communication and terahertz communication.

In other embodiments, the communication entity may be a device having wireless signal receiving and processing capabilities and the communication object is a device having wireless signal receiving and/or processing capabilities.

Before the communication body and the communication target perform wireless communication, the resource management body may configure communication resources, aware resources, and communication confirmation methods for the communication body and the communication target in advance, and send configuration messages to the communication body and the communication target.

The communication resource at least comprises resource position information of data sent by a communication main body, feedback resource position information of a communication target and the like; the perceived resource includes resource location information of the communication body transmitting the wireless perceived signal. For example, fig. 2 is a schematic diagram of resource allocation according to an embodiment of the present application, where the resource allocation is performed for at least one subframe period. As shown in fig. 2, subframes 0 to 4 may be regarded as one subframe period, and the resource management body configures subframes 0 to 2 to the communication body for transmitting communication data to the communication target, configures subframe 3 to the communication body for transmitting a wireless sensing signal, and configures subframe 4 to the communication target for feeding back information to the communication body; accordingly, the subframes 5 to 9 can be regarded as another subframe period, and the resource management body configures the subframes 5 to 7 to the communication body for transmitting communication data to the communication target, configures the subframe 8 to the communication body for transmitting a wireless sensing signal, and configures the subframe 9 to the communication target for feeding back information resources to the communication body.

In some embodiments, the communication confirmation means includes one of: a traditional confirmation mode, a confirmation mode based on wireless sensing, a diversity confirmation mode and a hybrid confirmation mode; the traditional confirmation mode is that a communication target sends a confirmation message to a communication main body through configured feedback resources, wherein the confirmation message is used for indicating the receiving condition of communication data; the confirmation mode based on wireless perception means that the communication main body sends wireless perception signals to the communication target through the configured perception resources, so that echo signals of the communication main body are perceived to confirm the receiving condition of communication data; the diversity confirmation mode is to adopt a traditional confirmation mode and a confirmation mode based on wireless perception for the same communication data; the hybrid acknowledgement mode refers to a traditional acknowledgement mode for one communication data and a wireless perception-based acknowledgement mode for the other communication data.

The resource management body may be a network device for managing and allocating radio resources, which can manage, control and schedule radio resources required for the communication body to communicate with the communication destination through radio resource control signaling (Radio Resource Control, RRC).

Step 102, a communication main body sends a wireless sensing signal to the communication target through at least one second subframe to obtain an echo signal of the wireless sensing signal reflected by the communication target aiming at the receiving condition of the first data; wherein the at least one second subframe precedes a third subframe, the third subframe being used to carry information fed back by the communication target for the first data.

In the embodiment of the present application, the wireless sensing signal may or may not carry communication data. The type of the wireless sensing signal is not limited, and may be a deterministic signal or a non-deterministic signal.

In the present application, the number of the first and second subframes is not limited, and may be one or more. For example, as shown in fig. 2, subframes 0 to 4 are taken as an example, wherein subframes 0 to 2 are all first subframes, subframe 3 is a second subframe, subframe 4 is a third subframe, that is, a D subframe is a first subframe, a S subframe is a second subframe, and a U subframe is a third subframe.

As can be easily understood, compared with the case that the communication target feeds back the first data to the communication main body through the U subframe, the communication main body sends the wireless sensing signal through the S subframe to realize the confirmation of the first data receiving condition, and the confirmation time is advanced by one subframe; thus, not only the resources of the forward link are fully utilized, but also the feedback delay in the transmission process is reduced. The forward link refers to a transmission link from a communication subject to a communication destination.

Step 103, the communication main body determines the receiving condition of the communication target on the first data at least based on the echo signal.

In the present application, the basis for determining the reception condition of the first data by the communication target is not limited, and is at least based on the echo signal. For example, in some embodiments, the communication body may implement step 103 through steps 401 to 406 of the following embodiments; in other embodiments, step 103 may be implemented by steps 501 through 507;

it can be understood that after the communication main body sends the first data to the communication target through at least one first subframe, the communication target regulates and controls the information coding module of the communication target in at least one second subframe according to the receiving condition of the first data, so that the information coding module can reflect the corresponding echo signal for the wireless sensing signal sent by the communication main body in the at least one second subframe after being regulated and controlled.

In some embodiments, the resource management entity may also configure the perceived signal modulation parameters, i.e. the modulation parameters required to configure the manner in which the communication entity and the communication target agree on echo regulation, prior to the communication entity and the communication target wirelessly communicating.

In some embodiments, the communication target may be configured with an information encoding module, which may perform echo regulation on the wireless sensing signal sent by the communication body, where the echo regulation may be performed by adopting a backscatter coupling manner. Fig. 3 is a schematic diagram of echo regulation provided in the embodiment of the present application, and as shown in fig. 3, a process of echo regulation is described:

Assuming that the first data is sent out through a plurality of first subframes, in some embodiments, an information encoding module in a communication target performs joint encoding on the receiving condition of the first data, where the joint encoding may be in a bitmap mode, or a codebook mode, or may be simple block encoding, and a sequence is obtained after encoding, where "0" does not change the phase of a wireless sensing signal, and "1" makes a 180-degree offset to the phase of the wireless sensing signal, and a communication body determines the receiving condition of the communication target on the first data by comparing the phases of the wireless sensing signal and an echo signal.

In some embodiments, the reception situation may be an ACK, NACK, or transmission delay. The ACK indicates that the communication target received the first data, the NACK indicates that the communication target did not receive the first data, and the transmission timeout indicates that the communication target did not receive the first data within a specific time.

Further, in some embodiments, if the communication body determines that the reception condition is NACK or the transmission is timeout, the communication body returns to perform step 101.

In the embodiment of the application, since the wireless sensing mode is adopted to confirm whether the first data is received by the communication target and the wireless sensing signal is sent before the third subframe, compared with the mode of only waiting for the feedback confirmation message of the communication target in the third subframe, the confirmation time is advanced, thereby shortening the feedback time delay in the transmission process, further shortening the overall communication time delay and improving the communication performance.

Fig. 4 is a schematic implementation flow chart of another communication confirmation method provided in an embodiment of the present application, as shown in fig. 4, the method may include the following steps 401 to 406:

step 401, the communication main body sends first data to the communication target through at least one first subframe;

step 402, the communication target receives the first data in the at least one first subframe;

step 403, the communication target regulates and controls the information coding module of the communication target in at least one second subframe according to the receiving condition of the first data, so that the information coding module can reflect corresponding echo signals for wireless sensing signals sent by the communication main body in the at least one second subframe after being regulated and controlled;

step 404, the communication main body sends a wireless sensing signal to the communication target through the at least one second subframe, and obtains an echo signal of the wireless sensing signal reflected by the communication target for the receiving condition of the first data; wherein the at least one second subframe precedes a third subframe, the third subframe being used for carrying information fed back by the communication target for the first data;

step 405, the communication body compares the phases of the echo signal and the wireless sensing signal to obtain a first sequence;

In step 406, the communication body decodes the first sequence, and determines the receiving condition of the communication target on the first data.

For example, the communication target encodes based on the reception condition of the first data, to obtain a first sequence 001100, where the former 00 indicates that ACK is successfully received, that is, data corresponding to subframe 0 is successfully received, 11 indicates that NACK is not received, that is, data corresponding to subframe 1 is not received, and the latter 00 indicates that ACK is successfully received, that is, data corresponding to subframe 2 is successfully received. The communication body may decode the first sequence according to the correspondence.

In some embodiments, if the reception is a NACK or the transmission times out, step 401 is entered.

It can be understood that, the communication main body sends the wireless sensing signal in the forward link through at least one second subframe, and confirms the receiving condition of the first data according to the echo signal thereof, compared with the receiving condition of the first data fed back to the communication main body through the feedback link in the third subframe by the communication target, that is, the communication main body confirms the receiving condition of the first data based on the wireless sensing confirmation mode compared with the traditional confirmation mode, thereby saving the feedback resource from the communication target to the communication main body link, shortening the communication feedback time delay and further improving the communication performance.

Fig. 5 is a schematic implementation flow chart of another communication confirmation method according to an embodiment of the present application, as shown in fig. 5, the method may include the following steps 501 to 507:

step 501, the communication main body transmits first data to the communication target through at least one first subframe;

step 502, the communication target receives the first data in the at least one first subframe;

step 503, according to the receiving condition of the first data, the communication target regulates and controls an information coding module of the communication target in at least one second subframe, so that the information coding module can reflect a corresponding echo signal for a wireless sensing signal sent by the communication main body in the at least one second subframe after being regulated and controlled;

step 504, the communication main body sends a wireless sensing signal to the communication target through the at least one second subframe to obtain an echo signal of the wireless sensing signal reflected by the communication target for the receiving condition of the first data; wherein the at least one second subframe precedes a third subframe, the third subframe being used for carrying information fed back by the communication target for the first data;

in step 505, the communication target sends a first acknowledgement message to the communication body in the third subframe.

In some embodiments, the first acknowledgement message may be an encoded sequence with a check code.

In step 506, the communication body receives, in the third subframe, a first acknowledgement message sent by the communication target, where the first acknowledgement message is used to indicate a receiving situation of the first data by the communication target.

In some embodiments, the first acknowledgement message is communication data sent by the communication target over the feedback link with a certain reliability. The feedback link refers to a transmission link from a communication target to a communication subject.

In step 507, the communication body determines a receiving condition of the first data by the communication target based on the echo signal, the wireless sensing signal and the first acknowledgement message.

In some embodiments, if the reception is a NACK or the transmission times out, go to step 501.

Fig. 6 is another schematic diagram of resource allocation provided in the embodiment of the present application, where at least one subframe period is allocated to resources, and as shown in fig. 6, subframes 0 to 4 may be regarded as one subframe period, where the resource management body allocates subframes 0 to 2 to the communication body, for sending communication data to the communication target, allocates subframe 3 to the communication body, for sending a wireless sensing signal, allocates subframe 4 to the communication target, and for feeding back information resources to the communication body; accordingly, the subframes 5 to 9 can be regarded as another subframe period, and the resource management body configures the subframes 5 to 7 to the communication body for transmitting communication data to the communication target, configures the subframe 8 to the communication body for transmitting a wireless sensing signal, and configures the subframe 9 to the communication target for feeding back information resources to the communication body.

In the present application, the number of the first and second subframes is not limited, and may be one or more. Taking subframes 0 to 4 as examples, where subframes 0 to 2 are all first subframes, subframe 3 is a second subframe, subframe 4 is a third subframe, that is, a D subframe is a first subframe, a S subframe is a second subframe, and a U subframe is a third subframe.

Easily understood, not only the communication target can feed back the receiving condition of the first data to the communication main body through the U subframe, but also the communication main body can send a wireless sensing signal through the S subframe to realize confirmation of the receiving condition of the first data; in this way, the feedback reliability of the first data reception situation is further ensured.

In some embodiments, as shown in fig. 7, the communication body may implement step 507 by steps 701 to 704 as follows:

in step 701, the communication body compares phases of the echo signal and the wireless sensing signal to obtain a first sequence.

In some embodiments, the communication destination encodes based on the reception of the first data to obtain the first sequence. The first sequence includes a check code.

In some embodiments, the check code may be a parity check code, a hamming check code, a cyclic redundancy check code, or the like, which may be used to error-correct and check the information code in the first sequence.

In step 702, the communication body performs parsing processing on the first acknowledgement message to obtain a second sequence.

The communication body analyzes the received first confirmation message to obtain a sequence with a check code, namely a second sequence.

In some embodiments, the check code may be a parity check code, a hamming check code, a cyclic redundancy check code, or the like, which may be used to error-correct and check the information code in the second sequence.

Step 703, merging the first sequence and the second sequence to obtain a merged sequence.

The first sequence and the second sequence are obtained by adopting the same coding mode, and can adopt the same coding version or different coding versions.

And step 704, performing error correction decoding on the information code in the combined sequence by using the check code in the combined sequence to obtain the receiving condition of the communication target on the first data.

It will be appreciated that longer check codes may be obtained after combining, and that the longer the check code, the more error correction capability. Therefore, the check code is utilized to carry out error correction decoding on the information code in the combined sequence, so that the accuracy of a decoding result can be improved, and the accuracy of a feedback result is further improved; accordingly, the number of data retransmissions is reduced, thereby shortening the overall communication delay.

In some embodiments, the information codes may be decoded after error correction by using the combined check codes, or the information codes may be decoded first, and the decoding result may be corrected by using the combined check codes after decoding is completed. That is, in the present application, the method of error correction decoding is not limited, and any error correction decoding method using a check code may be used, and in any case, a decoded result after error correction may be obtained.

In still other embodiments, as shown in fig. 8, the communication body may also implement step 507 by the following steps 801 to 803.

Step 801, determining a first receiving situation of the first data by the communication target based on the echo signal and the wireless sensing signal.

In some embodiments, the information encoding module in the communication target performs joint encoding on the reception situation of the first data, and obtains a reception situation sequence with a check code, namely a first sequence after encoding.

Step 802, determining a second receiving situation of the first data by the communication target based on the first acknowledgement message.

In some embodiments, the communication body parses the modulated first acknowledgement message to obtain a coded sequence with a check code, i.e. a second sequence.

Step 803, determining a receiving situation of the first data by the communication target based on the first receiving situation and the second receiving situation.

In some embodiments, when the first reception situation and the second reception situation are different, the communication body may treat the first reception situation or the second reception situation as a final reception situation of the first data. In some cases, the reliability of the second reception case is stronger than that of the first reception case, and therefore, in the case where the two acknowledgement results are inconsistent, the second reception case may be regarded as the final reception case of the first data.

Fig. 9 is a schematic implementation flow chart of a further communication confirmation method according to an embodiment of the present application, as shown in fig. 9, the method may include the following steps 901 to 910:

step 901, the communication main body transmits first data to the communication target through at least one first subframe;

step 902, the communication target receives the first data in the at least one first subframe;

step 903, the communication target regulates and controls an information coding module of the communication target in at least one second subframe according to the receiving condition of the first data, so that the information coding module can reflect a corresponding echo signal for a wireless sensing signal sent by the communication main body in the at least one second subframe after being regulated and controlled;

Step 904, the communication main body sends a wireless sensing signal to the communication target through the at least one second subframe to obtain an echo signal of the wireless sensing signal reflected by the communication target aiming at the receiving condition of the first data; wherein the at least one second subframe precedes a third subframe, the third subframe being used for carrying information fed back by the communication target for the first data;

step 905, the communication main body determines, based on the echo signal, a receiving condition of the first data by the communication target;

in some embodiments, if the reception is a NACK or the transmission times out, go to step 901; if the reception is an ACK, step 906 is performed.

Step 906, the communication body transmits the second data to the communication destination through at least one fourth subframe;

step 907, the communication target receives the second data in the at least one fourth subframe;

step 908, the communication target sends a second acknowledgement message to the communication body in at least one of the third subframes;

step 909, the communication main body receives a second acknowledgement message sent by the communication target in the at least one third subframe, where the second acknowledgement message is used to indicate the receiving situation of the second data by the communication target;

Step 910, determining, based on the second acknowledgement message, a reception situation of the second data by the communication target.

In some embodiments, the second data is received as a NACK or a transmission timeout, step 906.

Fig. 10 is a schematic diagram of another resource configuration provided in an embodiment of the present application, where the resource configuration is performed for at least one subframe period. As shown in fig. 2, subframes 0 to 4 can be regarded as one subframe period, and the resource management body configures subframes 0, 1, 3 for the communication body to transmit communication data to the communication destination, configures subframe 2 for the communication body to transmit a wireless sense signal, and configures subframe 4 for the communication destination to feed back information resources to the communication body; accordingly, the subframes 5 to 9 can be regarded as another subframe period, the resource management body configures the subframes 5, 6, 8 to the communication body for transmitting communication data to the communication target, configures the subframe 7 to the communication body for transmitting a wireless sensing signal, and configures the subframe 9 to the communication target for feeding back information resources to the communication body;

in the present application, the number of the first, second, third, and fourth subframes is not limited, and may be one or more. Taking subframes 0 to 4 as examples, wherein subframes 0 to 1 are all first subframes, subframe 2 is a second subframe, subframe 3 is a fourth subframe, subframe 4 is a third subframe, that is, a D1 subframe is a first subframe, a S subframe is a second subframe, a U subframe is a third subframe, and a D2 subframe is a fourth subframe.

It is easy to understand that, not only the communication main body can send the wireless sensing signal through the S subframe to realize the confirmation of the receiving condition of the first data, but also the communication target can feed back the receiving condition of the second data to the communication main body through the U subframe, so that the burden of the feedback link is reduced while the feedback delay of part of the confirmation message is reduced.

Both 4G and 5G use a communication acknowledgement mechanism in wireless transmission to ensure transmission reliability, i.e. the receiving end feeds back a piece of response information (such as ACK or NACK) whether to successfully receive the received information, which is set in the MAC layer, RLC layer), and layer PDCP. However, the acknowledgement mechanism, while guaranteeing the reliability of the transmission, also introduces a transmission delay. The service with higher real-time requirement is influenced by the confirmation mechanism, and the service quality is even not applicable.

New services such as artificial intelligence service and immersive service for 6G are continuously developed, and transmission delay needs to be further reduced while reliability is ensured. One idea is to further reduce the acknowledgement feedback time interval, i.e. the transmission time interval (Transmission Time Interval, TTI). The other thought adopts self-adaptive transmission, so that the successful receiving probability is improved, and the confirmation feedback frequency is reduced.

In addition, the service also needs to sense the service environment and the target state at any time, so that the sensing capability requirement is provided for the network and the terminal. This demand has prompted the development of communication awareness integration technology. Configuring communication awareness integrated devices would be a capability trend for 6G base stations and terminals.

The conventional acknowledgement mechanism has the disadvantage that the feedback procedure increases the overhead of the feedback link, especially in multi-user environments and multi-process situations. Another acknowledgement feedback failure typically results in a sender waiting for transmission, a transmission interruption, and even a service interruption.

In addition, the technology of integrating sensing and communication is not effectively utilized, and the technology stays on the design concept of sharing frequency spectrum and sharing hardware resources, and does not deeply integrate wireless communication and wireless sensing. In fact, wireless communication is similar to the principle of wireless sensing, which may also have the function of wireless communication. In addition, the wireless sensing is a front link of communication in the service flow, and is also a rear link of communication, that is, if the communication result is confirmed in the rear wireless sensing link of communication, the confirmation effect is better than the confirmation effect of the communication itself.

Based on this, an exemplary application of the embodiments of the present application in one practical application scenario will be described below.

In the embodiment of the application, aiming at the problem of enhancement of a communication confirmation mechanism, a sensing communication integrated technology is adopted, and a wireless sensing means is utilized to replace or assist in confirming feedback, so that the reliability of feedback is improved, the feedback time delay is reduced, and the feedback overhead is reduced.

In some embodiments, the implementation steps of the communication confirmation method include the following steps 1 to 4:

step 1: the system (i.e. the resource management main body) configures communication resources and perceived resources, and sends configuration information of the communication resources and configuration information of the perceived resources to the communication main body and the communication target;

the configured communication resources are time-frequency domain resources and space domain resources for communication. The allocated sensing resources are time-frequency domain resources and space domain resources for transmitting wireless sensing signals.

The communication resource configuration message and the sensing resource configuration message at least comprise resource position information for transmitting communication data, resource position information for transmitting wireless sensing signals and sensing signal modulation parameters.

Step 2: and according to the communication resource allocation situation and the perceived resource allocation situation, the system configures a communication confirmation mode and sends a communication confirmation mode configuration message to the communication main body and the communication target.

The communication acknowledgement mode configuration message includes at least an acknowledgement mode and a feedback resource location.

The communication confirmation method comprises a traditional confirmation method, a confirmation method based on wireless sensing, a diversity confirmation method and a hybrid confirmation method. The confirmation mode based on wireless perception refers to confirmation of information receiving condition through the wireless perception mode. The mixed confirmation mode is a traditional confirmation mode and a confirmation mode based on perception which are started by the system at the same time.

The communication body configures a communication-aware integrated device having wireless communication and wireless awareness functions. The communication target configures an information coding module according to the requirement of a communication confirmation mode, and the module can carry out echo regulation and control on the wireless sensing signal of the communication main body.

The echo regulation refers to that the information coding module modulates the data receiving condition into the echo of the wireless sensing signal in a scattering coupling mode.

Step 3: the communication body transmits wireless communication data (i.e., first data and/or second data) carrying information on the communication resource, and transmits a wireless sense signal on the sense resource. A wireless sense signal is a deterministic signal that does not carry communication data.

Step 4: and the communication target receives the wireless communication data at the corresponding communication resource position and feeds back a confirmation message at the confirmation feedback resource position according to the confirmation mode.

If the conventional acknowledgement scheme is configured, the communication target feeds back an acknowledgement message (i.e., the first acknowledgement message and/or the second acknowledgement message) in accordance with the conventional acknowledgement scheme.

If a confirmation mode based on perception is configured, the communication target carries out information coding on the wireless communication data receiving condition, echo regulation and control are carried out on a perception signal sent by the communication main body, and the communication main body detects the regulated echo to obtain the data receiving condition.

If the mixed confirmation mode is configured, the conventional confirmation mode and the confirmation mode flow based on the perception mode are executed at the same time, and fusion judgment is carried out on the confirmation results of the conventional confirmation mode and the confirmation result based on the perception mode, so that a final result is given.

Example 1

Step 1: the system configures forward link communication resources in subframes 0, 1, 2, 5, 6, 7 and configures sensing resources in subframes 3 and 8 as shown in fig. 2. The system configuration feeds back the receiving condition in the subframe 3 and the subframe 8 based on the wireless perception confirmation mode, and notifies the communication main body and the communication target.

The communication body configures a communication-aware integrated device having wireless communication and wireless awareness functions. And the communication target configuration information coding module can carry out echo regulation and control on the wireless sensing signal of the communication main body.

Step 2: the communication main body transmits communication data to the communication destination in subframes 0, 1, 2, 5, 6, and 7, and transmits a wireless sense signal in subframes 3 and 8.

Step 3: the communication target receives communication data in subframes 0, 1, 2, 5, 6 and 7, wherein the receiving conditions of the subframes 0, 1 and 2 are jointly encoded, and echo regulation is carried out on wireless sensing signals of a communication main body in a subframe 3; the receiving conditions of the subframes 5, 6 and 7 are jointly encoded, and the wireless sensing signal of the communication main body is subjected to echo regulation in the subframe 8.

The joint coding can be bitmap mode, codebook mode or simple block coding. In fig. 3, the reception cases obtained by subframes 0, 1, 2 are ACK, NACK, and ACK, respectively, and the coding sequence is 001100.

Echo regulation is carried out by adopting a back scattering coupling mode. In the 001100 sequence, bit "0" does not change the perceived signal echo phase, and bit "1" shifts the perceived signal phase 180 degrees. The receiver of the communication main body detects that the receiving condition code sequence is 001100 by comparing the phases of the wireless sensing signal and the echo signal, and finally obtains the results of ACK, NACK and ACK by decoding.

Step 4: the communication main body receives the regulated echo signals in the subframe 3 and the subframe 8 respectively, and detects the echo to obtain the receiving condition. If NACK exists or the transmission is overtime in the receiving condition, the step 2 is shifted to resend the corresponding information. Otherwise, the current flow ends.

Effects of example 1: the feedback delay of the acknowledgement message is reduced, and the resources of a feedback link are saved.

Example 2

Step 1: the system configures forward link communication resources at subframes 0, 1, 2, 5, 6, 7, perceptual resources at subframes 3 and 8, and feedback link communication subframes at subframes 4 and 9 as shown in fig. 6.

The system configures a diversity confirmation mode, feeds back the receiving condition in a mode based on wireless perception in the subframe 3 and the subframe 8, and feeds back the first confirmation message in a feedback link communication mode in the subframe 4 and the subframe 9.

The system transmits the perceived resource configuration information and the communication resource configuration information to the communication body and the communication target.

Step 2: the communication body transmits communication data to the communication destination in subframes 0, 1, 2, 5, 6, and 7, transmits a wireless sense signal in subframe 3 and subframe 8, and configures a feedback link communication subframe in subframe 4 and subframe 9.

Step 3: the communication target carries out joint coding on the receiving conditions of subframes 0, 1 and 2 after receiving communication data in subframes 0, 1, 2, 5, 6 and 7, carries out echo regulation and control on wireless sensing signals of a communication main body in subframe 3, and feeds back the wireless sensing signals through a feedback link in subframe 4; the reception conditions of the subframes 5, 6, and 7 are jointly encoded, the radio sensing signal of the communication body is echo-controlled in the subframe 8, and the first acknowledgement message is fed back through the feedback link in the subframe 9.

The receiving condition coding sequence fed back by the subframe 3 and the first acknowledgement message coding sequence fed back by the subframe 4 can adopt the same coding mode or different coding modes. If the same coding mode is adopted, different versions of coding sequences (used for soft combining at the receiving end) are generated. Subframe 8 and subframe 9 are handled similarly.

Step 4: the communication main body receives the regulated echo signals in the subframe 3 and the subframe 8 respectively, and detects the echo to obtain the receiving condition. The communicating body receives and detects the first acknowledgement message in sub-frame 4 and sub-frame 9, respectively.

If the subframe 3 and the subframe 4 adopt different coding modes and the decoding results are the same, a receiving condition is obtained, and if the decoding results are different, the receiving result of the subframe 4 is the right. If the same coding mode is adopted for the subframe 3 and the subframe 4, the receiving condition is obtained after soft combining. Subframe 8 and subframe 9 are handled similarly.

Step 5: if NACK exists or the transmission is overtime in the receiving condition, the step 2 is shifted to resend the corresponding information. Otherwise, the current flow ends.

Effects of example 2: by means of diversity confirmation, feedback reliability is enhanced.

Example 3

The system configures resources as shown in fig. 10, and the effect of embodiment 3 is similar to that of embodiment 1, and reduces the uplink feedback resource burden while reducing the feedback delay of a part of acknowledgement messages.

In the embodiment of the application, the communication confirmation mode can be fed back in a wireless sensing mode or in a hybrid confirmation mode, so that the burden of a feedback link can be reduced.

In the embodiment of the application, in the hybrid acknowledgement mode, the coding sequence corresponding to the conventional acknowledgement mode and the coding sequence corresponding to the wireless sensing mode are processed in the communication main body in a soft combining mode.

The communication confirmation method is suitable for intelligent agent near-distance information interaction, and comprises unmanned scenes, unmanned logistics scenes, unmanned manufacturing scenes and the like.

The communication confirmation method provided by the application can be backwards compatible with a traditional communication confirmation mechanism, and forward supports a non-communication confirmation mechanism.

The communication confirmation method can support a communication failure scene and realize information interaction only by means of wireless sensing signals.
