Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0158] In some embodiments of the present disclosure, the aforementioned communication system may be a synaesthesia-integrated system, where wireless communication technology and wireless sensing technology share a high degree of similarity. Synaesthesia-integrated systems can combine wireless communication and wireless sensing, fostering close collaboration between the two, thereby improving spectrum efficiency and reducing network deployment costs.

[0159] In some embodiments, wireless sensing requires estimating the distance, azimuth angle (such as horizontal and vertical angles), and speed of the sensing target. Optionally, sensing also includes wireless tracking and radio frequency identification of the sensing target.

[0160] In some embodiments, to achieve high-precision sensing, the transmitter may send a dedicated sensing signal (e.g., a reference signal). This reference signal may be referred to as a sensing reference signal. In bistatic mode, the receiver measures the sensing signal to estimate the distance, angle, and / or speed of the sensing target. In monostatic mode, the receiver measures the echo of the sensing signal to estimate the distance, angle, and / or speed of the sensing target.

[0161] In monostatic mode, the transmitter and receiver are co-located, for example, they are deployed on the same device. In bistatic mode, the receiver and transmitter are not co-located, for example, they are deployed on different devices or in different locations on the same device.

[0162] In some embodiments, sensing signals can be multiplexed with communication signals. For example, wireless sensing signals and communication signals (including data payload and reference signals in wireless communications) share a two-dimensional time-frequency resource grid. Compared to wireless communication links designed to maximize throughput, wireless sensing links are more sensitive to interference. In other words, once sensing signals are subject to interference, the accuracy and performance of wireless sensing are significantly degraded.

[0163] Therefore, how to achieve the coordination of communication signals and perception signals has become an urgent problem to be solved.

[0164] FIG2A is a flow chart of a signal transmission method according to an embodiment of the present disclosure. The method may be performed by the above-mentioned communication system. As shown in FIG2A , the method may include:

[0165] Step S2101: The transmitter determines a first parameter.

[0166] In some embodiments, the transmitting end may be used to transmit a signal, for example, a communication signal and / or a perception signal. Similarly, the receiving end may be used to receive a signal, for example, a communication signal and / or a perception signal.

[0167] The communication signal may include a signal used to perform wireless communication (eg, voice or data), such as a signal carrying a reference signal, control signaling, service data, etc. The communication signal may also be referred to as a wireless communication signal.

[0168] The sensing signal may be a signal for performing wireless sensing, for example, a sensing signal sent by a transmitter. The sensing signal may include a sensing reference message, a reference signal specifically used for sensing, or other signals used for performing wireless sensing.

[0169] In the synaesthesia integration scenario involved in the embodiments of the present disclosure, the transmitter that sends the communication signal and the transmitter that sends the perception signal can be the same transmitter or different transmitters. Similarly, the receiver that receives the communication signal and the receiver that receives the perception signal can be the same receiver or different receivers. The transmitter and receiver can be set on the same device or on different devices.

[0170] In some embodiments, the name of the transmitting end is not limited, and may be, for example, a "transmitter," a "wireless transmitter," a "wireless communication transmitter," a "wireless sensing transmitter," or a "synaesthesia integrated transmitter." The name of the receiving end is not limited, and may be, for example, a "receiver," a "wireless receiver," a "wireless communication receiver," a "wireless sensing receiver," or a "synaesthesia integrated receiver."

[0171] In some embodiments, the first parameter may be used to determine a first radio resource occupied by the sensing signal, where the first radio resource may include at least one resource element (RE), at least one resource element group (REG), at least one resource block (RB), or at least one resource block group (RBG). It should be noted that the resource element RE may also be referred to as a resource unit or a resource element.

[0172] In some embodiments, the first parameter may be used to determine a second radio resource not occupied by the sensing signal. Similarly, the second radio resource may include at least one RE, at least one REG, at least one RB, or at least one RBG.

[0173] In some embodiments, the name of the first parameter is not limited, for example, it can be "rate matching pattern", "rate matching mode", "rate matching parameter", "RateMatchPattern", "rate matching pattern based on coprime integers", "RateMatchPattern-Coprime", "perception reference signal pattern", "perception signal resource determination parameter", etc.

[0174] In some embodiments, the first parameter may define a new pattern type (patternType) in the RateMatchPattern of the 3GPP protocol, or may define a new RRC information element in the 3GPP protocol, for example, a rate matching pattern based on coprime integers (RateMatchPattern-Coprime).

[0175] In some embodiments, the transmitting end may receive the first parameter sent by other entities.

[0176] In some embodiments, the transmitting end may obtain the above-mentioned first parameter specified by the protocol.

[0177] In some embodiments, the transmitter may obtain the first parameter from an upper layer(s).

[0178] In some embodiments, the transmitting end may perform processing to obtain the first parameter. For example, the transmitting end may pre-configure the first parameter.

[0179] In some embodiments, step S2101 may be omitted, and the transmitting end may autonomously implement the function indicated by the first parameter, or the first parameter may be default or acquiescent.

[0180] Step S2102: The transmitting end determines a first wireless resource occupied by the perception signal.

[0181] In some embodiments, the first radio resource occupied by the perception signal may also be referred to as the first radio resource used to carry the perception signal. For example, the transmitting end may determine the first radio resource used to carry the perception signal.

[0182] In some embodiments, the transmitting end may determine the first wireless resource occupied by the perception signal based on the above-mentioned first parameter.

[0183] For example, the transmitter can determine the frequency domain position and time domain position occupied by the perception signal respectively, and determine the first wireless resource based on the frequency domain position and the time domain position. For example, the transmitter can determine the first wireless resource based on the intersection of the frequency domain position and the time domain position.

[0184] For example, the transmitting end may determine a first position set and a second position set according to the first parameter, and determine the frequency domain positions occupied by the perception signals according to the first position set and the second position set.

[0185] For example, the first wireless resource is a resource particle RE, the first position set and the second position set can be used to indicate the subcarrier position, and the subcarrier positions in the first position set and the second position set can be taken as the union to obtain the subcarrier position set, and the RE corresponding to the subcarrier position set is used as the frequency domain position occupied by the perception signal.

[0186] In some embodiments, the subcarrier positions indicated by the first position set are uniformly distributed, the subcarrier positions indicated by the second position set are uniformly distributed, and the subcarrier positions indicated by the subcarrier position set are non-uniformly distributed.

[0187] According to the above technical solution, the transmitting end can first determine two position sets with uniformly distributed subcarrier positions based on the first parameter, and then obtain a subcarrier position set with non-uniformly distributed subcarrier positions based on the two position sets. The transmitting end sends a perception signal based on the non-uniformly distributed subcarrier positions.

[0188] In some embodiments, the frequency domain positions of the subcarriers in the first position set and the frequency domain positions of the subcarriers in the second position set may be determined according to a pair of mutually prime positive integers.

[0189] According to the above technical solution, the transmitting end can determine two position sets in which the subcarrier positions are evenly distributed based on the parameters used to determine the subcarrier positions, and the subcarrier frequency domain intervals in the two position sets are determined based on a pair of mutually prime positive integers. Therefore, except for the subcarrier position at position 0 in the two position sets, the remaining subcarrier positions do not overlap. Then, a subcarrier position set in which the subcarrier positions are non-uniformly distributed is obtained based on the two position sets, and the transmitting end determines the frequency domain position occupied by the perception signal based on the non-uniformly distributed subcarrier positions.

[0190] The frequency domain pattern of the perceptual signal with non-uniform frequency domain distribution provided by the subcarrier position set in the embodiment of the present disclosure can achieve a large uniform degree of freedom in the Khatri-Rao subspace and avoid multiple mirror images of the channel impulse response observed at the receiving end.

[0191] In some embodiments of the present disclosure, the first parameter may include:

[0192] A first frequency domain interval P;

[0193] a second frequency domain interval Q, where P and Q are a pair of mutually prime positive integers, and P is smaller than Q, for example, P=2, Q=5;

[0194] Minimum frequency domain interval K min , the K min is a positive integer. The minimum frequency domain spacing can also be called the minimum subcarrier spacing.

[0195] In some embodiments, the minimum frequency domain interval K min May be predefined by the protocol.

[0196] In some embodiments, K min ∈{2,4,6,12}.

[0197] In some embodiments, the transmitter can calculate q*P*K based on min , take integers from 0 to Q-1 for the variable q, get the first position set, and based on the calculation formula p*Q*K min , take integers from 1 to 2P-1 for the variable p in turn to obtain the second position set.

[0198] It can be understood that each number in the first position set and the second position set respectively indicates a subcarrier position in an OFDM (Orthogonal Frequency Division Multiplexing) system.

[0199] In this case, the number of subcarrier positions indicated by the first position set is Q, and the subcarrier frequency domain spacing is P*K min , the number of subcarrier positions indicated by the second position set is 2P-1, and the subcarrier frequency domain spacing is Q*K min .

[0200] The subcarrier position set can be expressed as: {q*P*K min |q=0,1,…,Q-1}∪{p*Q*K min |p=1,2,…,2P-1}

[0201] For example, assuming K min is 2, P is 5, Q is 7, then:

[0202] The first position set is {0,10,20,30,40,50,60};

[0203] The second position set is {14, 28, 42, 56, 70, 84, 98, 112, 126}.

[0204] It can be obtained that the subcarrier position set is {0, 10, 14, 20, 28, 30, 40, 42, 50, 56, 60, 70, 84, 98, 112, 126}.

[0205] In other embodiments, the transmitter can calculate q*P*K based on the formula min , take integers from 1 to Q-1 for the variable q, get the first position set, and based on the calculation formula p*Q*K min , take integers from 0 to 2P-1 for the variable p in turn to obtain the second position set.

[0206] In this case, the number of subcarrier positions indicated by the first position set is Q-1, and the subcarrier frequency domain spacing is P*K min , the number of subcarrier positions indicated by the second position set is 2P, and the subcarrier frequency domain spacing is Q*Kmin .

[0207] The subcarrier position set can be expressed as: {q*P*K min |q=1,2,…,Q-1}∪{p*Q*K min |p=0,1,2,…,2P-1}

[0208] For example, assuming K min is 2, P is 5, Q is 7, then:

[0209] The first position set is {10,20,30,40,50,60};

[0210] The second position set is {0, 14, 28, 42, 56, 70, 84, 98, 112, 126}.

[0211] It can be obtained that the subcarrier position set is {0, 10, 14, 20, 28, 30, 40, 42, 50, 56, 60, 70, 84, 98, 112, 126}.

[0212] In other embodiments, the transmitter can calculate q*P*K based on the formula min , take integers from 0 to Q-1 for the variable q, get the first position set, and based on the calculation formula p*Q*K min , take integers from 0 to 2P-1 for the variable p in turn to obtain the second position set.

[0213] In this case, the number of subcarrier positions indicated by the first position set is Q, and the subcarrier frequency domain spacing is P*K min , the number of subcarrier positions indicated by the second position set is 2P, and the subcarrier frequency domain spacing is Q*K min .

[0214] The subcarrier position set can be expressed as: {q*P*K min |q=0,1,2,…,Q-1}∪{p*Q*K min |p=0,1,2,…,2P-1}

[0215] For example, assuming K min is 2, P is 5, Q is 7, then:

[0216] The first position set is {0,10,20,30,40,50,60};

[0217] The second position set is {0, 14, 28, 42, 56, 70, 84, 98, 112, 126}.

[0218] It can be obtained that the subcarrier position set is {0, 10, 14, 20, 28, 30, 40, 42, 50, 56, 60, 70, 84, 98, 112, 126}.

[0219] According to the above technical solution, the frequency domain pattern of the perception signal with non-uniform frequency domain distribution provided by the subcarrier position set in the embodiment of the present disclosure can reduce the resource overhead and total transmission power of the perception signal, and can achieve higher time domain resolution and higher perception accuracy.

[0220] In some other embodiments of the present disclosure, the first parameter may further include at least one of the following:

[0221] Frequency domain offset k, where k is less than or equal to K min The frequency domain offset may also be referred to as a subcarrier offset. The frequency domain offset k is used to indicate the offset of the starting frequency domain (e.g., subcarrier) occupied by the perception signal relative to the Nth frequency domain (e.g., subcarrier) in a PRB, where N is a non-negative integer, for example, N may be 0.

[0222] The starting physical resource block PRB number is K0, where K0 is a non-negative integer. K0 is the offset of the starting PRB of the first radio resource relative to the Nth common resource block CRB, where N is a preset non-negative integer. Optionally, N may be 0, and the Nth common resource block CRB may be CRB0. For example, the starting physical resource block PRB number is 2, which may indicate that the perception signal is carried starting from the second PRB relative to CRB0, that is, the PRB starting from the 24th resource element RE is used to indicate that the perception signal is carried.

[0223] In some embodiments, the transmitter can calculate q*P*K based on min +k, take integers from 0 to Q-1 for the variable q, get the first position set, and based on the calculation formula p*Q*K min +k, take integers from 1 to 2P-1 for the variable p in sequence to obtain the second position set.

[0224] In this case, the number of subcarrier positions indicated by the first position set is Q, and the subcarrier frequency domain spacing is P*K min , the number of subcarrier positions indicated by the second position set is 2P-1, and the subcarrier frequency domain spacing is Q*K min .

[0225] The subcarrier position set can be expressed as: {q*P*K min +k|q=0,1,…,Q-1}∪{p*Q*K min +k|p=1,2,…,2P-1}

[0226] In other embodiments, the transmitter can calculate q*P*K based on the formula min +k, take integers from 1 to Q-1 for the variable q, get the first position set, and based on the calculation formula p*Q*K min +k, take integers from 0 to 2P-1 for the variable p in sequence to obtain the second position set.

[0228] The subcarrier position set can be expressed as: {q*P*K min +k|q=1,2,…,Q-1}∪{p*Q*K min +k|p=0,1,2,…,2P-1}

[0229] In other embodiments, the transmitter can calculate q*P*K based on the formula min +k, take integers from 0 to Q-1 for the variable q, get the first position set, and based on the calculation formula p*Q*K min +k, take integers from 0 to 2P-1 for the variable p in sequence to obtain the second position set.

[0230] In this case, the number of subcarrier positions indicated by the first position set is Q, and the subcarrier frequency domain spacing is P*K min , the number of subcarrier positions indicated by the second position set is 2P, and the subcarrier frequency domain spacing is Q*K min .

[0231] The subcarrier position set can be expressed as: {q*P*K min +k|q=0,1,2,…,Q-1}∪{p*Q*K min +k|p=0,1,2,…,2P-1}

[0232] It can be understood that the subcarrier conflicts of different sensing links or communication networks can be avoided by flexibly setting the value of k.

[0233] In some embodiments, the transmitter can calculate q*P*K based on min +k+K0, take integers from 0 to Q-1 for the variable q, get the first position set, and based on the calculation formula p*Q*K min +k, take integers from 1 to 2P-1 for the variable p in sequence to obtain the second position set.

[0234] In this case, the number of subcarrier positions indicated by the first position set is Q, and the subcarrier frequency domain spacing is P*K min , the number of subcarrier positions indicated by the second position set is 2P-1, and the subcarrier frequency domain spacing is Q*K min .

[0235] The subcarrier position set can be expressed as: {q*P*K min +k+K0|q=0,1,…,Q-1}∪{p*Q*K min +k+K0|p=1,2,…,2P-1}

[0236] In other embodiments, the transmitter can calculate q*P*K based on the formula min +k+K0, take integers from 1 to Q-1 for the variable q, get the first position set, and based on the calculation formula p*Q*K min +k+K0, take integers from 0 to 2P-1 for the variable p in sequence to obtain the second position set.

[0241] The subcarrier position set can be expressed as: {q*P*K min +k+K0|q=0,1,2,…,Q-1}∪{p*Q*K min+k+K0|p=0,1,2,…,2P-1}

[0242] It can be understood that by flexibly setting the values ​​of k and K0, conflicts between subcarriers of different sensing links or communication networks can be avoided.

[0243] In some embodiments of the present disclosure, the time domain position occupied by the perception signal may be a first time domain position, and the first time domain position may be a time domain position specified by a protocol, or a time domain position pre-negotiated between the transmitter and the receiver.

[0244] For example, the first time domain position may be the Nth symbol position of each time slot, where N may be any non-negative integer, such as any non-negative integer between 0 and 13. N may be 5, or may be 5 and 9.

[0245] For another example, the first time domain position may be the Nth symbol position of each even time slot, for example, the Nth symbol position of the 0th time slot.

[0246] For another example, the first time domain position may be the Nth symbol position of each odd-numbered time slot, for example, the Nth symbol position of the 1st time slot.

[0247] For another example, the first time domain position may be the Nth symbol position of a specific time slot among multiple time slots, and the specific time slot may be the Nth symbol position of a specific time slot among multiple time slots according to S offset Determined time slots. For example, every T slot The Sth time slot offset The Nth symbol position in the time slot. slot =3 and S offset =1, the first time slot position is the Nth symbol position of the first time slot in every three time slots.

[0248] For another example, the first time domain position may be the Nth symbol position of the Mth time slot of each subframe, where M may be 0 or 1, and N may be any non-negative integer between 0 and 13.

[0249] For another example, the first time domain position may be the Nth symbol position of the Mth time slot of the Pth subframe of each frame, where P may be any non-negative integer between 0 and 9, M may be 0 or 1, and N may be any non-negative integer between 0 and 13.

[0250] It should be noted that the first time domain position may be any time domain position specified by the protocol or negotiated in advance.

[0251] In some embodiments of the present disclosure, the first time domain position may be a time domain position determined according to a first parameter.

[0252] The first parameter may further include at least one of the following:

[0253] A time domain symbol number set L is used to determine the time domain symbols in a time slot. For example, L={5,9} is used to indicate that the first 5 symbols and the ninth symbol in a time slot are used to carry perception signals.

[0254] Time domain period T slot , the T slot is a positive integer; the T slot It can be used to determine the number of time slots contained in a cycle. Each time domain cycle T slot There may be at least one time slot used to carry a sensing signal.

[0255] Time slot offset S offset , the S offset is less than T slot The time slot offset is used to determine the position of the time slot carrying the sensing signal within a time domain period, for example, T slot is 2, S offset If it is 0, it means that each time domain cycle contains 2 time slots, numbered 0 and 1 respectively, where the 0th time slot is used to carry the perception signal, and the 1st time slot does not carry the perception signal.

[0256] The starting timeslot number S0 is a non-negative integer. The starting timeslot number S0 is used to determine the number of the starting timeslot that begins carrying the perception signal. For example, if the starting timeslot number S0 is 6, it means that the starting timeslot number used to carry the perception signal is 6. A timeslot contains 14 symbols, which means that the timeslot starting from the 84th symbol is used to carry the perception signal.

[0257] Number of time slots S num , the S num Is a positive integer. It is used to indicate the number of repetitions of the time domain cycle. For example, the number of time slots S num If it is 3, it means that the total number of time slots used to carry the perception signal is 3.

[0258] In some embodiments, the above L, T slot 、S offset , S0 and S num At least one item in can be used to determine the time domain position occupied by the perception signal, and the time domain position information can be a symbol position.

[0259] In some embodiments of the present disclosure, the first parameter may include at least one of the following:

[0271] Figure 2B is a schematic diagram of resource occupancy of a perception signal according to an embodiment of the present disclosure. As shown in Figure 2B, the horizontal axis represents the symbol number in the time domain, the vertical axis represents the subcarrier number in the frequency domain, and a rectangular grid represents a resource element RE. The black-filled rectangular grid represents the resource element used to carry the perception signal (that is, the first wireless resource occupied by the perception signal), and the unfilled rectangular grid represents the resource element not used to carry the perception signal (that is, the second wireless resource not occupied by the perception signal).

[0272] It should be noted that the schematic diagram of resource occupancy of the perception signal shown in FIG2B can also be referred to as a schematic diagram of resource occupancy of the perception signal based on a coprime integer pattern. The perception signal shown in FIG2B can be a resource occupied by the perception signal determined based on a first parameter, and the first parameter can be:

[0282] The starting time slot number S0 is 6;

[0283] Number of time slots S num is 3.

[0284] Step S2103: The transmitting end sends the first parameter to the receiving end.

[0285] In some embodiments, the receiving end may receive the first parameter. For example, the receiving end may receive the first parameter sent by the transmitting end. For another example, the receiving end may also receive the first parameter sent by another entity.

[0286] In some embodiments, the transmitting end may send a first message, which may include the first parameter. For example, the transmitting end may send the first message to the receiving end. Optionally, the receiving end may receive the first message.

[0287] In one implementation, the transmitting end is a network device and the receiving end is a terminal device, and the first message may be a radio resource control (RRC) message. For example, when the transmitting end is a network device and the receiving end is a terminal device, the first message may be an RRC message.

[0288] In another implementation, the transmitting end and the receiving end are both terminal devices, and the first message may be a direct link RRC message, which may be an RRC message of the PC5 interface. For example, when the transmitting end and the receiving end are both terminal devices, the first message may be an RRC message.

[0289] In other embodiments, the transmitting end may send a second message, which may include one or more second parameters; the transmitting end may also send indication information, which may be used to instruct the receiving end to determine the first parameter from the above one or more second parameters.

[0290] Similarly, the receiving end may receive the second message and obtain one or more second parameters. The receiving end may also receive indication information and determine the first parameter from the one or more second parameters according to the indication information.

[0291] In some embodiments, the one or more second parameters may include the first parameter.

[0292] In some embodiments, the name of the second parameter is not limited, for example, it can be "rate matching pattern", "rate matching mode", "rate matching parameter", "RateMatchPattern", "rate matching pattern based on coprime integers", "RateMatchPattern-Coprime", "perception reference signal pattern", "perception signal resource determination parameter", etc.

[0293] For example, the above-mentioned second parameter may be an RMP (Rate Match Pattern), and the above-mentioned one or more second parameters may constitute an RMP set. One or more RMPs may be determined from the RMP set as the first parameter through the indication information.

[0294] For another example, the transmitter can carry multiple second parameters (such as RMP1, RMP2, RMP3, etc.) through a second message (such as an RRC message or a Sidelink RRC message), and can indicate the number of the second parameter (such as 1, 2 or 3) through indication information (such as DCI), and use the second parameter corresponding to the number as the first parameter.

[0426] FIG6 is a flow chart of a signal transmission method according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to a signal transmission method, which can be executed by a communication system and may include:

[0427] Step S6101: Determine the first parameter.

[0428] In some embodiments, to indicate that resource elements occupied by a coprime integer pattern-based perception reference signal are unavailable to the wireless communication system, a new rate matching pattern or a new RRC information element is defined based on the first parameter. For example, a new patternType is defined in the RateMatchPattern of the 3GPP protocol, or a new RRC information element RateMatchPattern-Coprime is defined in the 3GPP protocol.

[0429] The first parameter may include at least one of the following parameters:

[0430] Rate matching pattern type indication (pattenType), for example, the rate matching pattern type indication may be a coprime integer type (Coprime);

[0431] A first frequency domain interval P;

[0432] The second frequency domain interval Q;

[0433] Minimum frequency domain interval K min ;

[0434] Frequency domain offset k;

[0435] The starting physical resource block PRB number is K0;

[0436] A time domain symbol number set L;

[0437] Time domain period T slot ;

[0438] Time slot offset S offset ;

[0439] The starting time slot number is S0;

[0440] Number of time slots S num .

[0441] Step S6102: The transmitter sends a first parameter.

[0442] The transmitting end (eg, a wireless transmitter) generates a rate matching pattern (eg, a first parameter) based on the perceptual reference signal pattern, and notifies the receiving end (eg, a wireless communication receiver) of the rate matching pattern through signaling.

[0443] In some embodiments, if the transmitting end is a network device (such as a base station) and the receiving end is a terminal device, the above signaling is RRC signaling.

[0444] Optionally, the transmitter or wireless communication network may configure multiple RMPs via RRC signaling to form an RMP set. The transmitter may then dynamically select a subset (including one or more RMPs) from the RMP set via DCI signaling and indicate this to the receiver.

[0445] In other embodiments, if both the transmitting end and the receiving end are terminal devices, the RMP may be indicated by RRC signaling of the PC5 interface.

[0446] Step S6103: The transmitter sends a communication signal.

[0447] For example, the transmitting end maps the communication signal (including data payload and wireless communication reference signal, etc.) to resource elements other than the perception reference signal (indicated by the rate matching pattern described in 1) and sends it.

[0448] Step S6104: The receiving end determines the resource elements occupied by the sensing signal.

[0449] For example, the receiving end may receive the rate matching pattern (eg, the first parameter) and determine the coordinate positions of the resource elements occupied by the perception reference signal on the time-frequency two-dimensional resource grid according to the rate matching pattern.

[0450] Step S6104: The receiving end receives the communication signal

[0451] For example, when receiving wireless communication data, the receiving end performs rate matching on the resource elements described in 4, that is, skips the resource elements occupied by the sensing reference signal and does not receive the wireless communication signal.

[0452] In some embodiments, in a synaesthesia system, the perception reference signal adopts a pattern based on coprime integers, as shown in FIG2B . The transmitter generates a rate matching pattern as follows and notifies the receiving end (e.g., a wireless communication receiver) via RRC signaling. When performing resource mapping, the transmitter performs rate matching according to the rate matching pattern. Accordingly, the receiver receives the rate matching pattern and determines the coordinate position of the resource element occupied by the perception reference signal on the time-frequency two-dimensional resource grid based on it, and skips the resource element when receiving communication data, that is, does not detect the received signal on the resource element.

[0453] In some embodiments of the present disclosure, a communication system is provided, which may include a receiving end and a transmitting end, wherein the receiving end can execute the signal transmission method executed by the receiving end in the aforementioned embodiment of the present disclosure; the transmitting end can execute the signal transmission method executed by the transmitting end in the aforementioned embodiment of the present disclosure.

All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
