For example, in some scenarios or implementations, sensing categories may be shown in the following Table 1:
It should be noted that the sensing categories shown in the foregoing Table 1 is merely an example for description, and a sensing measurement category is not limited in the embodiments of this application.
In addition, the embodiments of this application may be applied to an integrated communication and sensing application scenario in integration of communication and a radar. In this scenario, a joint design includes spectrum coexistence, that is, two systems work independently, and information exchange may be allowed to reduce mutual interference. In the case of sharing at a receive end, transmit ends of the two systems send respective signal waveforms, and the waveforms of the two systems need to be orthogonal, thus not affecting respective receiving and detection; in the case of sharing at a transmit end, the transmit end transmits a joint waveform of a radar and communication; and in the case of sharing at a transmit end and a receive end, resources are shared on a transmit end and a receive end of the two systems, and similarly, a joint waveform or waveforms in an orthogonal relationship need to be used. It should be noted that the foregoing integrated communication and sensing application scenario in integration of communication and a radar is an example of application scenarios of the embodiments of this application, and a corresponding scenario is not limited in the embodiments of this application.
In the embodiments of this application, during sensing, sensing may be performed based on a single-station mode, that is, transmit/receive co-location. A transmit end transmits a sensing signal, and then receives and analyzes an echo signal to extract a sensing parameter. For example, as shown in
In the embodiments of this application, a communication system may jointly send a modulation symbol that carries information and a pilot symbol that is used for channel estimation, and focuses on decoding performance. A channel estimation algorithm of the communication system only needs to estimate a composite channel that has finite unknown parameters, and generally an optimization objective is to improve a throughput and transmission reliability. Performance indicators that are concerned are usually spectrum efficiency, a channel capacity, a Signal-to-Noise Ratio (SNR), a Signal to Interference plus Noise Ratio (SINR), a Bit Error Ratio (BER), a BLock Error Rate (BLER), a Symbol Error Rate (SER), and the like. However, an information carrying problem is not considered in a signal sending process of a sensing system. Generally, an optimized or unmodulated transmit signal is used, and a change, that is, a response characteristic, that is brought by a sensing target to a transmit signal is focused. Generally, an optimization target is to improve parameter estimation precision. A performance measurement indicator may be a fuzzy function, a Cramer-Rao lower bound, a root mean square error, mutual information, a rate distortion function, a radar estimation rate, a Welch lower bound, and some indicators associated with a sensing scenario and a requirement.
In the embodiments of this application, in some scenarios or implementations, both a wireless communication signal and a wireless sensing signal are supported, and an integrated communication and sensing function design is implemented by using an integrated communication and sensing means such as a signal joint design and/or hardware sharing, so that a sensing capability or a sensing service is provided while information transmission is performed. In this way, cost saving, device size reducing, device power consumption reducing, spectrum efficiency improving, reducing of mutual interference between communication and sensing, and system performance improving can be achieved by means of integrated communication and sensing.
In addition, integrated sensing and communication may include but is not limited to at least one of the following:
In the embodiments of this application, for a communication and sensing fusion scenario or an integrated sensing and communication scenario, a dedicated sensing signal may be used for sensing measurement, or a communication signal, such as data and/or a pilot, may be reused. For use of a sensing measurement signal, a sending party may instruct a receiving party, for example, a base station instructs a terminal to use which type of signal for sensing measurement.
With reference to the accompanying drawings, the following describes in detail an indication information sending method and apparatus, an indication information receiving method and apparatus, a device, and a storage medium provided in the embodiments of this application by using some embodiments and application scenarios thereof.
Referring to
Step 401: A first device sends first indication information to a second device, where the first indication information is used to indicate m pieces of sensing measurement result validity and n pieces of communication data reception correctness, m and n are positive integers, and m+n>2, where
The first device may be a network side device or a terminal, and the second device may be a sensing network function and/or a sensing network element in a core network, or may be a network side device or a terminal.
In this embodiment of this application, the target signal may be a communication signal such as a reference signal, a synchronization signal, or a data signal, or the target signal may be a dedicated sensing signal such as a radar pulse signal or a Frequency Modulated Continuous Wave (FMCW) signal.
The target signal may be received and sent in the following several manners:
It should be noted that the target signal in this embodiment of this application may be sent by a plurality of devices, and the target signal may be received by a plurality of devices.
The first indication information may explicitly or implicitly indicate the m pieces of sensing measurement result validity and the n pieces of communication data reception correctness.
The m pieces of sensing measurement result validity may be m sensing measurement result validity indications. Each piece of sensing measurement result validity is used to indicate validity or invalidity of a corresponding sensing measurement result, and each sensing measurement result or each sensing measurement result validity indication is associated with one or more sensing measurements, where one sensing measurement may be measurement based on one or more target signals.
In addition, a criterion for whether a sensing measurement result is valid or invalid may be configured by a network device and/or defined by a protocol, or a criterion for whether a sensing measurement result is valid or invalid is determined by being associated with a sensing measurement quantity or a sensing requirement or a sensing service.
The n pieces of communication data reception correctness may be n communication data reception correctness indications, and each indication represents reception correctness of one or more data transmissions. For example, n pieces of communication data reception confirmation information are n ACKnowledgements (ACK) or n Negative ACKnowledgement (NACK) of receiving communication data, or a total quantity of ACKs and NACKs is n.
In this embodiment of this application, through the foregoing steps, the first device may indicate the m pieces of sensing measurement result validity and the n pieces of communication data reception correctness to the second device, so as to implement sensing measurement, thereby improving working performance of the device. In addition, because m+n>2, a plurality of feedback results can be indicated at one time, so as to reduce transmission overheads.
In addition, in this embodiment of this application, content indicated by the first indication information further includes further processing or signal configuration adjustment on a sensing measurement result by the second device that receives the first indication information, so as to improve sensing measurement performance. In some implementations, content indicated by the first indication information may assist a party that receives a sensing measurement result to further process the sensing measurement result or adjust a configuration of a sensing measurement signal, so as to obtain better sensing measurement performance.
In an implementation, the first indication information includes an indication bit, and the indication bit is at least one bit indicating the m pieces of sensing measurement result validity and the n pieces of communication data reception correctness.
The indication bit may indicate the m pieces of sensing measurement result validity, and n bits indicate the n pieces of communication data reception correctness through joint coding or independent coding.
In an implementation, the indication bit is m+n bits, where
The m bits and the n bits respectively indicate the m pieces of sensing measurement result validity and the n pieces of communication data reception correctness. Joint coding or independent coding may be adopted, where bit rates in the independent coding may be different, so that different priority or importance requirements can be met. In addition, that the m bits indicate the m pieces of sensing measurement result validity may be: for each 1 bit in the m bits, “0” indicates that a sensing measurement result is invalid, and “1” indicates that a sensing measurement result is valid; and the n bits indicate the n pieces of communication data reception correctness, that is, indicates n ACKs/NACKs. For example, for each of the n bits, “0” indicates that communication data is incorrectly received (NACK), and “1” indicates that communication data is correctly received (ACK).
The x pieces of sensing measurement result validity and the x pieces of communication data reception correctness may be that there are x associated sensing measurement result validity and communication data reception correctness indications in the m pieces of sensing measurement result validity and the n pieces of communication data reception correctness. In this case, the x pieces of sensing measurement result validity and the x pieces of communication data reception correctness may be indicated by using 2x bits through joint coding. Each associated 2 bits in the 2x bits jointly indicate sensing measurement result validity and communication data reception correctness through joint coding, that is, each 2 bits represent four states. In particular, for example, if a case that communication data is incorrectly received but a sensing measurement result is valid does not exist, a value of 2 bits corresponding to the state (communication data is incorrectly received and a sensing measurement result is valid) may be Reserved. For example, as shown in Table 2 below:
Remaining m−x bits and n−x bits may respectively indicate sensing measurement result validity and communication data reception correctness. When there are the following cases: x=m, x=n, and x=m=n, there may be no bit for independently indicating sensing measurement result validity and/or communication data reception correctness. That is, in a case that m−x bits in the m+n bits indicate m−x pieces of sensing measurement result validity, and in a case that x is less than n, n−x bits in the m+n bits indicate n−x pieces of sensing measurement result validity.
In this implementation, sensing measurement result validity and communication data reception correctness can be accurately indicated by using m+n bits.
In an implementation, the indication bit is 2 bits, a first value of a first bit in the 2 bits indicates that at least one of the m pieces of sensing measurement result validity is invalid, and a second value of the first bit indicates that all the m pieces of sensing measurement result validity are valid; and a first value of a second bit in the 2 bits indicates that at least one of the n pieces of communication data reception correctness is incorrect, and a second value of the second bit in the 2 bits indicates that all the n pieces of communication data reception correctness are correct.
In this implementation, 1 bit may be used as a logic AND result of m bits used to indicate the m pieces of sensing measurement result validity. For example, “0” indicates that at least one of the m sensing measurement results is invalid, and “1” indicates that all the m sensing measurement results are valid. The other 1 bit is used as a logic AND result of n bits used to indicate the n pieces of communication data reception correctness. For example, “0” indicates that at least one of the n communication data reception correctness indications is a reception incorrect indication (NACK), and “1” indicates that all the n communication data reception correctness indications are reception correct indications (ACK).
In this implementation, signaling overheads can be reduced by using 2 bits.
In an implementation, the indication bit is 1 bit, a second value of the first bit indicates that all the m pieces of sensing measurement result validity are valid, all the n pieces of communication data reception correctness are correct, and a first value of the 1 bit indicates at least one of the following:
In this implementation, 1 bit is used as a logic AND result of m bits used to indicate the m pieces of sensing measurement result validity and n bits used to indicate communication data reception correctness. For example, “O” indicates that at least one of the m sensing measurement results is invalid and/or at least one of the n communication data reception correctness indications is a reception incorrect indication (NACK), and “1” indicates that all the m sensing measurement results are valid and all the n communication data reception correctness indications are reception correct indications (ACK).
In this implementation, signaling overheads can be reduced by using 1 bit.
In an implementation, the indication bit is m+n−x bits, where x bits in the m+n−x bits respectively indicate x joint indications, and each joint indication is a joint indication of one piece of sensing measurement result validity and one piece of communication data reception correctness; and in a case that x is less than m, m−x bits in the m+n−x bits indicate m−x pieces of sensing measurement result validity, and in a case that x is less than n, n−x bits in the m+n−x bits indicate n−x pieces of sensing measurement result validity, where x is a positive integer, x is less than or equal to m, and x is less than or equal to n.
In this implementation, there may be x associated sensing measurement result validity and communication data reception correctness indications in the m sensing measurement result validity indications and the n communication data reception correctness indications. Each bit in the x bits is used to indicate a 2-bit logic AND logical result of associated sensing measurement result validity and communication data reception correctness. For example, each of the x bits is used to indicate associated sensing measurement result validity and communication data reception correctness. For example, “O” indicates that communication data is incorrectly received (NACK) or a sensing measurement result is invalid, and “1” indicates that communication data is correctly received (ACK) and a sensing measurement result is valid.
Remaining m−x bits and n−x bits respectively indicate sensing measurement result validity and communication data reception correctness. When the following cases exist: x=m<n, x=n<m, and x=m=n, there may be no bit for independently indicating sensing measurement result validity and/or communication data reception correctness. That is, in a case that x is less than m, m−x bits in the m+n−x bits indicate m−x pieces of sensing measurement result validity, and in a case that x is less than n, n−x bits in the m+n−x bits indicate n−x pieces of sensing measurement result validity.
In this implementation, signaling overheads can be reduced by using m+n−x bits.
In an implementation, the indication bit includes x bit groups, the x bit groups respectively indicate x joint indications, and each joint indication is a joint indication of one piece of sensing measurement result validity and one piece of communication data reception correctness, where
In this implementation, there are x associated sensing measurement result validity and communication data reception correctness indications in the m sensing measurement result validity indications and the n communication data reception correctness indications, and the x sensing measurement result validity indications perform indication based on sensing measurement result validity of communication data. Specifically, in a case that the target signal is a communication data signal, it may be determined to use 1 bit or 2 bits in each bit group based on communication data reception correctness. For example:
When communication data is incorrectly received, 1 bit is used for indication, where “0” indicates that communication data is incorrectly received (NACK) and a sensing measurement result is invalid; or
In addition, in this implementation, a communication data reception correctness indication and a sensing measurement result validity indication are independently coded, and the communication data reception correctness indication is located front.
In this implementation, 1 bit or 2 bits may be flexibly used to reduce signaling overheads.
In an implementation, the indication bit is m×u+n bits, where m×u bits respectively indicate levels of the m pieces of sensing measurement result validity, and n bits indicate the n pieces of communication data reception correctness.
The foregoing sensing measurement result validity level may be that different levels correspond to different signal quality, and the signal quality may include at least one of an SNR, a Reference Signal Received Power (RSRP), a Received Signal Strength Indication (RSSI), a signal clutter ratio, and the like; or the foregoing sensing measurement result validity level may be that different levels correspond to different sensing performance indicators; or the foregoing sensing measurement result validity level may be that different levels correspond to different measurement result validity thresholds. For example, it is assumed that there are two thresholds, and three levels are included, where one level represents being invalid, another level represents being valid for a first threshold but being invalid for a second threshold, and one another level represents being valid for the second threshold (it is assumed that the second threshold has a higher requirement).
In this implementation, sensing measurement result validity may be classified into different levels, so that a feedback effect of the sensing measurement result validity can be improved, and the m pieces of sensing measurement result validity and the n pieces of communication data reception correctness may be respectively by using m×u bits and n bits.
In an implementation, the first indication information is further used to indicate at least one of the following:
The sensing measurement result invalidity cause may be cause information of a sensing measurement result indicated as invalid in the m pieces of sensing measurement result validity.
The parameter configuration of the target signal may be a parameter configuration that is of the target signal and that is recommended or expected by the first device, and may be a parameter configuration of the target signal corresponding to a sensing measurement result indicated as invalid in the m pieces of sensing measurement result validity. The parameter configuration may be used to improve validity of a sensing measurement result corresponding to the target signal.
In this implementation, at least one of the invalidity cause and the parameter configuration is fed back, so that the second device that receives the first information can further process a sensing measurement result or adjust a signal configuration, so as to improve sensing measurement performance. In some implementations, at least one of the invalidity cause and the parameter configuration may assist a party that receives a sensing measurement result to further process the sensing measurement result, or adjust a configuration of a sensing measurement signal, so as to obtain better sensing measurement performance.
In some implementations, the sensing measurement result invalidity cause is at least one of the following:
That quality of the target signal detected by the first device does not reach a threshold requirement may be that at least one of an SNR, an RSRP, an RSSI, and a signal clutter ratio threshold of the target signal detected by the first device does not meet the threshold requirement. In addition, in a measurement process, a receive end may first measure at least one of an SNR, an RSRP, an RSSI, and a signal clutter ratio, and then measure a specific sensing measurement quantity if a threshold is reached.
That a sensing measurement result obtained by the first device does not meet a sensing requirement may be that a sensing performance indicator corresponding to the sensing measurement result obtained by the first device through calculation does not meet the requirement. For example, a sensing SNR is less than a preset threshold.
That the first device does not correctly demodulate data may be that, during sensing based on communication data, demodulation is performed first and then a sensing parameter is estimated, and if communication demodulation is incorrect, a sensing measurement result is affected and becomes unreliable, that is, the sensing measurement result is invalid.
That the first device does not obtain a sensing measurement result when a feedback time point of the first indication information arrives may be that a receive end fails to obtain a sensing measurement result when the feedback time point arrives, for example, sensing measurement result processing expires.
In some implementations, the parameter configuration includes at least one of the following:
The waveform may include Orthogonal Frequency Division Multiplex (OFDM), Single-Carrier Frequency-Division Multiple Access (SC-FDMA) SC-FDMA, Orthogonal Time Frequency Space (OTFS), a Frequency Modulated Continuous Wave (FMCW), a pulse signal, or the like.
The subcarrier spacing may be a subcarrier spacing 30 KHz, 15 KHz, or the like in an OFDM system.
The guard interval may be a time interval from a moment at which sending of a signal ends to a moment at which a latest echo signal of the signal is received. The parameter is proportional to a maximum sensing distance, for example, may be obtained through calculation by using 2dmax/c, where dmax is the maximum sensing distance (belonging to a sensing requirement). For a self-transmitting and self-receiving sensing signal, dmax represents a maximum distance between a sensing signal transmitting/receiving point and a signal transmit point. In some cases, an OFDM signal Cyclic Prefix (CP) may function as a minimum guard interval. In addition, c is an optical speed.
The bandwidth may be inversely proportional to distance resolution, for example, may be obtained by using c/2/delta_d, where delta_d is the distance resolution (belonging to a sensing requirement).
The burst duration may be inversely proportional to a rate resolution (belonging to a sensing requirement). The parameter is a time span of a sensing signal, and is mainly used to calculate a Doppler frequency offset. This parameter may be calculated by using c/2/delta_v/fc, where delta_v is speed resolution, and fc is a signal carrier frequency or a signal center frequency.
The time domain interval may be obtained through calculation by using c/2/fc/v_range, where v_range is a maximum rate minus a minimum speed (belonging to a sensing requirement). The parameter is a time interval between two adjacent sensing signals.
The transmit signal power may be a value obtained at intervals of 2 dBm from −20 dBm to 23d Bm. Certainly, this is merely an example, and may be specifically set according to an actual requirement.
The signal format may be information about a Sounding Reference Signal (SRS), a Demodulation Reference Signal (DMRS), a Positioning Reference Signal (PRS), or another predefined signal, and a related sequence format.
The signal direction may be direction or beam information of a sensing signal.
The time resource may include a slot index or a symbol index of a slot in which a sensing signal is located. There are two types of time resources: One is a one-time time resource, for example, one symbol is used to send an omnidirectional target signal; and the other is a non-one-time time resource, for example, a plurality of groups of periodic time resources or discontinuous time resources (which may include a start time and an end time), each group of periodic time resources are used to send sensing signals in a same direction, and beam directions of periodic time resources in different groups are different.
The frequency resource may include a center frequency, a bandwidth, a Resource Block (RB), a subcarrier, or the like of a sensing signal.
The QCL relationship may include: a QCL between each of a plurality of resources included in a sensing signal and a Synchronization Signal Block (SSB), where the QCL includes Type A, B, C, or D.
In this implementation, the second device can adjust a configuration of a sensing measurement signal by using the foregoing parameter configuration, so as to obtain better sensing measurement performance.
In an implementation, the first indication information is further used to indicate at least one of the following:
The identifier information of the target signal associated with the sensing measurement result may include identifier information of target signals associated with sensing measurement results corresponding to the m pieces of sensing measurement result validity.
The sensing measurement identifier information may include sensing measurement identifier information respectively corresponding to the m pieces of sensing measurement result validity.
The sensing measurement result may include sensing measurement results respectively corresponding to the m pieces of sensing measurement result validity.
The identifier information of the target signal associated with the sensing measurement result indicates which one or more target signals corresponding to sensing measurement result validity are indicated by the sensing measurement result validity indication information. In this way, sensing measurement result validity of a specific target signal can be indicated, so as to implement accurate indication.
The sensing measurement identifier information may indicate which sensing measurement corresponding to sensing measurement result validity is indicated by the sensing measurement result validity indication information, and the sensing measurement may be measurement based on one or more target signals. In this way, sensing measurement result validity of specific sensing measurement can be indicated, so as to implement accurate indication.
Indicating the sensing measurement result may be indicating a specific sensing measurement result.
The feedback information of the first indication information may include at least one of the following:
Through the feedback information, the second device can accurately obtain content indicated by the first indication information.
In an implementation, in a case that a first piece of sensing measurement result validity indicated in the first indication information is valid, the first indication information indicates a first sensing measurement result, and the first piece of sensing measurement result validity is one of the m pieces of sensing measurement result validity;
In this implementation, the first indication information includes the first sensing measurement result only when sensing measurement result validity indication information of a sensing measurement result in the first indication information indicates that a sensing measurement result is valid, so as to reduce signaling overheads.
Only when a sensing measurement result is valid, the first indication information sent by the second device to the first device includes a sensing measurement result validity indication of the sensing measurement result and/or the sensing measurement result and/or identifier information of a target signal associated with the sensing measurement result and/or sensing measurement identifier information, and when a measurement result is invalid, the first indication information does not include related feedback information of the first sensing measurement result, so as to reduce signaling overheads.
Only when a sensing measurement result is invalid, the first indication information sent by the second device to the first device includes a sensing measurement result validity indication of the sensing measurement result and/or a sensing measurement result invalidity cause and/or a recommended target signal parameter configuration, and when a measurement result is valid, the first indication information does not include related feedback information of the sensing measurement result, so as to reduce signaling overheads.
Only when sensing measurement result validity indication information of a sensing measurement result in the first indication information indicates that the sensing measurement result is invalid, the first indication information includes a sensing measurement result invalidity cause of the sensing measurement result and/or a recommended target signal parameter configuration, so as to reduce signaling overheads.
In an implementation, before the sending, by a first device, first indication information to a second device, the method further includes:
Whether the sensing measurement result validity needs to be fed back may indicate whether validity feedback needs to be performed on all or a part of sensing measurement results within a period of time (for example, from a current moment to a termination moment of a sensing service).

It should be noted that this embodiment is used as an implementation of the second device corresponding to the embodiment shown in
The following uses a plurality of embodiments to illustrate the method provided in the embodiments of this application.
This embodiment mainly describes a format of first indication information, which is specifically as follows:
In this embodiment, m sensing measurement result validity indications and n communication data reception correctness indications are fed back each time. As shown in
In this embodiment, the format of the first indication information may include the following:
Manner 1: That a measurement result is valid or a measurement result is invalid+communication data is correctly received or incorrectly received are fed back, which may be specifically as follows:
In manner 1, m+n bits may be fed back. For example:
In one case, m bits and n bits respectively indicate sensing measurement result validity and communication data reception correctness. Joint coding or independent coding may be adopted, where bit rates in the independent coding may be different, so that different priority or importance requirements can be met. The m bits indicate sensing measurement result validity. For example, for each 1 bit in the m bits, “0” indicates that a sensing measurement result is invalid, and “1” indicates that a sensing measurement result is valid; and the n bits indicate communication data reception correctness, that is, an ACK/a NACK. For example, for each of the n bits, “0” indicates that communication data is incorrectly received (NACK), and “1” indicates that communication data is correctly received (ACK).
In another case, there are x (x≤m and x≤n) associated sensing measurement result validity and communication data reception correctness indications (a total of 2×x bits) in the m sensing measurement result validity indications and the n communication data reception correctness indications. Each associated 2 bits jointly indicate sensing measurement result validity and communication data reception correctness through joint coding, that is, each 2 bits represent four states. In particular, for example, if a case that communication data is incorrectly received but a sensing measurement result is valid does not exist, a value of 2 bits corresponding to the state (communication data is incorrectly received and a sensing measurement result is valid) may be Reserved, as specifically shown in Table 2.
Remaining m−x bits and n−x bits respectively indicate sensing measurement result validity and communication data reception correctness, which may be specifically shown in Table 3.
It should be noted that an order of joint coding indication information, sensing measurement result validity indication information, and communication data reception correctness indication information is not limited, for example, may be determined according to a feedback priority. For details of the priority, refer to the corresponding descriptions of the foregoing embodiment. The three may be independently coded.
In particular, when there are the following cases: x=m, x=n, and x=m=n, there may be no bit for independently indicating sensing measurement result validity and/or communication data reception correctness, which may be shown in Table 4 to Table 6.
In manner 1, 2 bits may be fed back. For example, 1 bit is used as a logic AND result of m bits used to indicate m pieces of sensing measurement result validity, where “0” indicates that at least one of m sensing measurement results is invalid, and “1” indicates that all the m sensing measurement results are valid. The other 1 bit is used as a logic AND result of n bits used to indicate n pieces of communication data reception correctness, where “0” indicates that at least one of the n communication data reception correctness indications is a reception incorrect indication (NACK), and “1” indicates that all the n communication data reception correctness indications are reception correct indications (ACK).
In addition, 1 bit indicating sensing measurement result validity may be: “1” is fed back when more than x (x≤m, and the effect is equivalent to logic AND when x=m) of the m sensing measurement results are valid; otherwise, “0” is fed back.
In manner 1, 1 bit may be fed back. For example, as a logic AND result of m bits used to indicate sensing measurement result validity and n bits used to indicate communication data reception correctness, “0” indicates that at least one of m sensing measurement results is invalid or at least one of n communication data reception correctness indications is a reception incorrect indication (NACK), and “1” indicates that all the m sensing measurement results are valid and all the n communication data reception correctness indications are reception correct indications (ACK).
In manner 1, m+n−x bits may be fed back. There are x (x≤m and x≤n) associated sensing measurement result validity and communication data reception correctness indications (a total of 2x bits) in the m sensing measurement result validity indications and the n communication data reception correctness indications. Logic AND is performed on each associated 2 bits to obtain x bits. Each of the x bits is used to indicate associated sensing measurement result validity and communication data reception correctness, where “0” indicates that communication data is incorrectly received (NACK) or a sensing measurement result is invalid, and “1” indicates that communication data is correctly received (ACK) and a sensing measurement result is valid.
Remaining m−x bits and n−x bits respectively indicate sensing measurement result validity and communication data reception correctness. In particular, when the following cases exist: x=m<n, x=n<m, and x=m=n, there may be no bit for independently indicating sensing measurement result validity and/or communication data reception correctness. For a specific format, reference may be made to the formats shown in the foregoing Table 3 to Table 6, and joint coding indication information is 1 bit.
In manner 1, if there are x (x≤m and x≤n) associated sensing measurement result validity and communication data reception correctness indications (a total of 2×x bits) in the m sensing measurement result validity indications and the n communication data reception correctness indications, the x sensing measurement result validity indications are sensing measurement result validity indications based on communication data, that is, the target signal is a communication data signal, and each associated 2 bits may be represented by 1 bit or 2 bits. A specific method is as follows:
When communication data is incorrectly received, 1 bit is used for indication, where “0” indicates that communication data is incorrectly received (NACK) and a sensing measurement result is invalid; or
In addition, a communication data reception correctness indication and a sensing measurement result validity indication may be independently coded, and the communication data reception correctness indication is located front. For example, a second device first decodes the communication data reception correctness indication information to obtain n pieces of communication data reception correctness indication information and how many reception correct indication (ACK) exist in x pieces of communication reception correctness indication information associated with sensing, so that a quantity of bits for the subsequent sensing measurement result validity indication can be determined.
In manner 1, m×u+n (m>1) bits may be fed back, which may be specifically corresponding to validity of m sensing measurement results. Validity of each sensing measurement result is represented by using u bits, and corresponds to v states related to validity. Therefore, u=ceil (log 2(v)) bits are required. For example, validity of sensing measurement results is classified into different levels, that is, target signal quality (an SNR, an RSRP, an RSSI, a signal clutter ratio, or the like) or sensing performance indicators corresponding to measurement results are different. In some implementations, there are a plurality of thresholds for determining validity of a measurement result. (It is assumed that there are two thresholds), there may be three states: being invalid, being valid for a first threshold but being invalid for a second threshold, and being valid for the second threshold (it is assumed that the second threshold has a higher requirement). Sensing measurement result validity and communication data reception correctness may be respectively indicated by using m×u bits and n bits.
In manner 1, 1+n bits may be fed back. 1 bit may be a logic AND result of m sensing measurement result validity indication bits, where “0” indicates that at least one sensing measurement result is invalid, and “1” indicates that all m sensing measurement results are valid; or “1” is fed back when more than x (x<m) of m sensing measurement results are valid; otherwise, “0” is fed back. The other n bits are n communication data reception correctness indication bits.
In manner 1, m+1 bits may be fed back, where m bits are m sensing measurement result validity indication bits, and the other 1 bit is logic AND of n communication data reception correctness indication bits.
Manner 2: That a measurement result is valid+a sensing measurement result+a communication data reception correctness indication are fed back or that a measurement result is invalid+a communication data reception correctness indication are fed back, which may be specifically as follows:
When a sensing measurement result is valid, “1” is fed back to indicate that a sensing result is valid, the sensing measurement result is fed back, and a communication data reception correctness indication is fed back. When a sensing measurement result is invalid, “0” is fed back to indicate that a sensing result is invalid, and a communication data reception correctness indication is fed back. In some implementations, the format may include the following:
In one case, a sensing measurement result may be fed back each time when a validity indication is fed back, and then a communication data reception correctness indication is fed back, for example, as shown in the following Table 7:
In one case, n bit validity indications may be first fed back, then a sensing measurement result is fed back, and then a communication data reception correctness indication is fed back. For example, as shown in the following Table 8:
In one case, a sensing measurement result validity indication and a communication data reception correctness indication may be first fed back, and then a sensing measurement result is fed back. For example, as shown in the following Table 9:
It should be noted that the foregoing feedback format of the first indication information may also be that a communication data reception correctness indication is before a sensing measurement result validity indication and a sensing measurement result. For example, information with a higher priority is placed in the front. Communication is placed in the front when a communication feedback is more important, and conversely, sensing is placed in the front.
Further, in manner 2, a sensing measurement result validity indication bit and a communication data reception correctness indication bit may be combined for feedback according to the descriptions in manner 1; or a sensing measurement result validity indication is represented by using a plurality of bits.
It should be noted that, when a sensing measurement result is fed back, a quantity of bits of each sensing measurement result is fixed, and may be agreed upon by sending and receiving parties (specified in a protocol), or a quantity of bits of a sensing measurement result/a quantity of bits of the first indication information are/is indicated by a sending party of the first indication information. In particular, in some cases of manner 2, m-bit validity indications are before sensing results, and the validity indications and the sensing results may be separately coded. The second device first detects the preceding m-bit validity indications, and then knows a quantity of subsequent sensing results. In this case, a receive end can correctly perform decoding only a quantity of bits of each sensing measurement result is known. The same is true for the following feedback on a sensing measurement result invalidity cause and a recommended target signal parameter configuration.
Manner 3: That a measurement result is valid+a sensing measurement result+a communication data reception correctness indication are fed back or that a measurement result is invalid+an invalidity cause+a communication data reception correctness indication are fed back, which may be specifically as follows:
When a sensing measurement result is valid, “1” is fed back to indicate that a sensing result is valid, the sensing measurement result is fed back, and a communication data reception correctness indication is fed back. When a sensing measurement result is invalid, “0” is fed back to indicate that a sensing result is invalid, a sensing measurement result invalidity cause is fed back, and a communication data reception correctness indication is fed back. Specifically, the format may include the following:
In one case, a sensing measurement result or an invalidity cause may be fed back each time when a validity indication is fed back, and then a communication data reception correctness indication is fed back. For example, as shown in the following Table 10:
In one case, m-bit validity indications may be first fed back, then a sensing measurement result and an invalidity cause are sequentially fed back, and then a communication data reception correctness indication is fed back. For example, as shown in the following Table 11:
In manner 3, a communication data reception correctness indication may be placed before or after a sensing measurement result validity indication or the two are alternately fed back, and then a sensing measurement result and an invalidity cause are sequentially fed back.
In manner 3, a sensing measurement result when the sensing measurement result is valid and an invalidity cause when the sensing measurement result is invalid may be separately fed back, and then a communication data reception correctness indication is fed back. Assuming that there are x valid sensing measurement results and y invalid sensing measurement results, the x sensing measurement results and p (p≤y) invalidity causes are fed back. For example, as shown in the following Table 12:
It should be noted that, information with high importance or a high delay requirement may also be placed in front. For example, if a sensing measurement result is more important, the sensing measurement result is placed in front, or a sensing measurement result may be independently coded.
In some implementations, an invalidity cause may be before a sensing measurement result. In some implementations, a communication data reception correctness indication may be placed before or after a sensing measurement result validity indication or the two are alternately fed back, and then a sensing measurement result and an invalidity cause are separately fed back. For example, communication is placed in the front when a communication feedback is more important, and conversely, sensing is placed in the front. In addition, the same is true for the following order of a measurement result, an invalidity cause, and a recommended target signal parameter configuration.
Further, a sensing measurement result validity indication bit and a communication data reception correctness indication bit may be combined for feedback as described in manner 1; or a sensing measurement result validity indication is represented a plurality of multiple bits.
It should be noted that a quantity of invalidity causes that are fed back may be less than a quantity of invalid sensing measurement results, because a same invalidity cause may be fed back only once or only invalidity causes of a part of invalid sensing measurement results are selected to be fed back. Compared with a manner of sequentially feeding back a sensing measurement result and an invalidity cause, feedback overheads can be reduced. However, because a quantity of bits of the first indication information is uncertain, a total quantity of bits for feedback or a quantity of invalidity causes that are fed back need to be indicated. Otherwise, a receive end may not correctly decode the first indication information. In addition, the same is true for the following feedback on a sensing measurement result invalidity cause.
Manner 4: That a measurement result is valid+a sensing measurement result+a communication data reception correctness indication are fed back or that a measurement result is invalid+a recommended target signal parameter configuration+a communication data reception correctness indication are fed back, which may be specifically as follows:
When a sensing measurement result is valid, “1” is fed back to indicate that a sensing result is valid, the sensing measurement result is fed back, and a communication data reception correctness indication is fed back. When a sensing measurement result is invalid, “0” is fed back to indicate that a sensing result is invalid, a recommended target signal parameter configuration is fed back, and a communication data reception correctness indication is fed back.
The specific format may be described in the foregoing manner 3, where an invalidity cause is replaced with a recommended target signal parameter configuration.
It should be noted that a quantity of recommended parameter configurations that are fed back may be less than a quantity of invalid sensing measurement results, because a same recommended parameter configuration may be fed back only once or only a part of recommended parameter configurations are selected to be fed back. For example, if a recommended parameter configuration 1 is a bandwidth of 100 MHz, and a recommended parameter configuration 2 is a bandwidth of 120 MHZ, only the recommended parameter configuration 2 is selected to be fed back. Compared with a manner of sequentially feeding back a sensing measurement result and a recommended parameter configuration, feedback overheads can be reduced. However, because a quantity of bits of the first indication information is uncertain, a total quantity of bits for feedback or a quantity of recommended target signal parameter configurations that are fed back may be indicated, to avoid a possibility that the second device may not correctly decode the first indication information. In addition, the same is true for the following feedback on a recommended target signal parameter configuration.
Manner 5: That a measurement result is valid+a sensing measurement result+a communication data reception correctness indication are fed back or that a measurement result is invalid+an invalidity cause+a recommended target signal parameter configuration+a communication data reception correctness indication are fed back, which may be specifically as follows:
When a sensing measurement result is valid, “1” is fed back to indicate that a sensing result is valid, the sensing measurement result is fed back, and a communication data reception correctness indication is fed back. When a sensing measurement result is invalid, “0” is fed back to indicate that a sensing result is invalid, a sensing measurement result invalidity cause and a recommended target signal parameter configuration are fed back, and a communication data reception correctness indication is fed back.
The specific format is described in the foregoing manner 3, where an invalidity cause is replaced with an invalidity cause+a recommended target signal parameter configuration.
In addition, an order of a communication data reception correctness indication, a sensing measurement result validity indication, and a sensing measurement result validity indication or an invalidity cause may be determined according to feedback priorities, and an invalidity cause and a recommended target signal parameter configuration may also be determined according to importance. In this case, the two may be independently coded.
Manner 6: That a measurement result is valid+a communication data reception correctness indication are fed back or that a measurement result is invalid+an invalidity cause+communication data reception correctness indication are fed back, which may be specifically as follows:
When a sensing measurement result is valid, “1” is fed back to indicate that a sensing result is valid, and a communication data reception correctness indication is fed back. When a sensing measurement result is invalid, “0” is fed back to indicate that a sensing result is invalid, a sensing measurement result invalidity cause is fed back, and a communication data reception correctness indication is fed back.
The specific format is described in the foregoing manner 3, where a sensing measurement result is no longer fed back when a sensing measurement result is valid.
Manner 7: That a measurement result is valid+a communication data reception correctness indication are fed back or that a measurement result is invalid+a recommended target signal parameter configuration+a communication data reception correctness indication are fed back, which may be specifically as follows:
When a sensing measurement result is valid, “1” is fed back to indicate that a sensing result is valid, and a communication data reception correctness indication is fed back. When a sensing measurement result is invalid, “0” is fed back to indicate that a sensing result is invalid, a recommended target signal parameter configuration is fed back, and a communication data reception correctness indication is fed back.
The specific format is described in the foregoing manner 3, where a sensing measurement result is no longer fed back when a sensing measurement result is valid, and an invalidity cause is replaced with a recommended target signal parameter configuration.
Manner 8: That a measurement result is valid+a communication data reception correctness indication are fed back or that a measurement result is invalid+an invalidity cause+a recommended target signal parameter configuration+a communication data reception correctness indication are fed back, which may be specifically as follows:
When a sensing measurement result is valid, “1” is fed back to indicate that a sensing result is valid, and a communication data reception correctness indication is fed back. When a sensing measurement result is invalid, “0” is fed back to indicate that a sensing result is invalid, a recommended target signal parameter configuration is fed back, and a communication data reception correctness indication is fed back.
The specific format is described in the foregoing manner 5, where a sensing measurement result is no longer fed back when a sensing measurement result is valid.
In addition, only when a first sensing measurement result is valid, the first indication information sent by the first device to the second device includes a sensing measurement result validity indication of the first sensing measurement result and/or a sensing measurement result and/or target signal identifier information and/or sensing measurement identifier information that are/is associated with a sensing measurement result. When a measurement result is invalid, the first indication information does not include related feedback information of the first sensing measurement result, and the first sensing measurement result is one of the m sensing measurement results.
Only when a first sensing measurement result is invalid, the first indication information sent by the first device to the second device includes a sensing measurement result validity indication of the first sensing measurement result and/or a sensing measurement result invalidity cause and/or a recommended target signal parameter configuration; or when a measurement result is valid, the first indication information does not include related feedback information of the first sensing measurement result, and the first sensing measurement result is one of the m sensing measurement results.
In addition, in this embodiment of this application, a sensing measurement result, a sensing requirement, and a sensing service may be defined as follows:
The sensing measurement result is a measurement result associated with a sensing measurement quantity, that is, a value of a measurement quantity. Specifically, at least one of the following may be included:
In addition to the foregoing measurement quantities, a new measurement quantity generated by performing an operation based on two or more of the foregoing measurement quantities is included.
The sensing requirement information may include at least one of the following:
The sensing service may be at least one of the following:
In this embodiment of this application, the criterion for determining whether a sensing measurement result is valid may include at least one of the following:
When the sensing measurement result meets at least one of the foregoing, it is considered that a sensing measurement result is valid; otherwise, it is considered that a sensing measurement result is invalid. For example, when the first connection and the second condition are met, that is, the first signal quality meets the threshold requirement and the sensing measurement result meets the sensing requirement, it is considered that the sensing measurement result is valid.
In this embodiment of this application, a first device performs sensing measurement according to indication information related to a sensing measurement signal configuration, feeds back m pieces of sensing measurement result validity and n pieces of communication data reception correctness, and feeds back information such as a sensing measurement result, a sensing measurement result invalidity cause, and a recommended sensing measurement signal configuration according to the sensing measurement result validity. A feedback format is determined according to the sensing measurement result validity and the communication data reception correctness, so that overheads can be effectively reduced. A party that receives a sensing measurement result is assisted to further process the sensing measurement result, or adjust a configuration of a sensing measurement signal, so as to obtain better sensing measurement performance.
