In monostatic mode, the receiver estimates the distance, angle, and / or velocity of the sensed target by measuring the echo of the sensing signal.
[0160] In monostatic mode, the transmitter and receiver share the same address, for example, the transmitter and receiver are deployed on the same device. In bistatic mode, the receiver and transmitter do not share the same address, for example, the transmitter and receiver are deployed on different devices, or deployed in different locations on the same device.
[0161] In some embodiments, sensing signals can be multiplexed with communication signals. For example, sensing signals and communication signals (including data payloads and reference signals in wireless communication) share a time-frequency two-dimensional resource grid. Relatively speaking, wireless sensing links are more sensitive to interference than wireless communication links aimed at maximizing throughput. That is, once the sensing signal is interfered with, the accuracy and performance of its wireless sensing will significantly decrease.
[0162] Therefore, how to achieve the coordination between communication signals and sensing signals has become an urgent problem to be solved.
[0163] Figure 2 A is a schematic flowchart illustrating a signal transmission method according to an embodiment of this disclosure. This method can be executed by the aforementioned communication system. Figure 2 As shown in A, the method may include:
[0164] Step S2101: The transmitter determines the first parameter.
[0165] In some embodiments, the transmitting end can be used to transmit signals, for example, to transmit communication signals and / or sensing signals. Similarly, the receiving end can be used to receive signals, for example, to receive communication signals and / or sensing signals.
[0166] The communication signal may include signals used to perform wireless communication (e.g., voice or data), such as signals carrying reference signals, control signaling, service data, etc. This communication signal may also be referred to as a wireless communication signal.
[0167] The sensing signal can be a signal used to perform wireless sensing, for example, a signal transmitted by a transmitter for sensing. The sensing signal can include a sensing reference message, which can be a reference signal specifically used for sensing, or it can include other signals used to perform wireless sensing.
[0168] In the integrated sensing scenario disclosed in this embodiment, the transmitter sending the communication signal and the transmitter sending the sensing signal can be the same transmitter or different transmitters. Similarly, the receiver receiving the communication signal and the receiver receiving the sensing signal can be the same receiver or different receivers. The transmitter and receiver can be located on the same device or on different devices.
[0169] In some embodiments, the name of the transmitter is not limited, and may be, for example, "transmitter," "wireless transmitter," "wireless communication transmitter," "wireless sensing transmitter," "integrated sensing transmitter," etc. The name of the receiver is not limited, and may be, for example, "receiver," "wireless receiver," "wireless communication receiver," "wireless sensing receiver," "integrated sensing receiver," etc.
[0170] In some embodiments, the first parameter can be used to determine a first radio resource occupied by the sensed signal. 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 aforementioned resource element RE can also be referred to as a resource unit or resource element.
[0171] In some embodiments, the first parameter may be used to determine a second radio resource that is not occupied by the sensed 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.
[0172] In some embodiments, the name of the first parameter is not limited, and may be, for example, "rate matching pattern", "rate matching mode", "rate matching parameter", "RateMatchPattern", "rate matching pattern based on coprime integers", "RateMatchPattern-Coprime", "sensing reference signal pattern", "sensing signal resource determination parameter", etc.
[0173] In some embodiments, the first parameter can define a new pattern type in the 3GPP protocol's RateMatchPattern, or a new RRC cell in the 3GPP protocol, such as a rate-matching pattern based on coprime integers (RateMatchPattern-Coprime).
[0174] In some embodiments, the transmitter may receive the first parameter described above sent by other entities.
[0175] In some embodiments, the transmitter may obtain the first parameter specified in the protocol.
[0176] In some embodiments, the transmitter can obtain the first parameter mentioned above from the upper layer(s).
[0177] In some embodiments, the transmitter can process the data to obtain the first parameter described above. For example, the transmitter can pre-configure the first parameter.
[0178] In some embodiments, step S2101 can be omitted, and the transmitter can autonomously implement the function indicated by the first parameter, or the first parameter can be a default or default value.
[0179] Step S2102: The transmitting end determines the first wireless resource occupied by the sensing signal.
[0180] In some embodiments, the first wireless resource occupied by the sensing signal may also be referred to as the first wireless resource used to carry the sensing signal. For example, the transmitting end may determine the first wireless resource used to carry the sensing signal.
[0181] In some embodiments, the transmitter may determine the first wireless resource occupied by the sensing signal based on the first parameter described above.
[0182] For example, the transmitting end can determine the frequency domain location and time domain location occupied by the sensed signal, and determine the first wireless resource based on the frequency domain location and time domain location. For example, the first wireless resource can be determined based on the intersection of the frequency domain location and the time domain location.
[0183] For example, the transmitting end can determine a first set of positions and a second set of positions based on a first parameter, and determine the frequency domain position occupied by the sensing signal based on the first set of positions and the second set of positions.
[0184] For example, the first wireless resource is a resource particle (RE), and the first location set and the second location set can be used to indicate the subcarrier position. The subcarrier positions in the first location set and the second location set can be combined to obtain the subcarrier position set, and the RE corresponding to the subcarrier position set can be used as the frequency domain position occupied by the sensing signal.
[0185] In some embodiments, the subcarrier positions indicated by the first location set are uniformly distributed, the subcarrier positions indicated by the second location set are uniformly distributed, and the subcarrier positions indicated by the subcarrier position set are non-uniformly distributed.
[0186] According to the above technical solution, the transmitter can first determine two sets of locations where the subcarrier positions are uniformly distributed based on the first parameter, and then obtain a set of subcarrier positions where the subcarrier positions are non-uniformly distributed based on the two sets of locations. The transmitter then sends a sensing signal based on the non-uniformly distributed subcarrier positions.
[0187] In some embodiments, the subcarrier frequency domain positions in the first position set and the subcarrier frequency domain positions in the second position set can be determined based on a pair of coprime positive integers.
[0188] According to the above technical solution, the transmitter can determine two sets of locations where the subcarrier positions are uniformly distributed based on the parameters used to determine the subcarrier positions. The frequency domain interval of the subcarriers in the two sets of locations is determined based on a pair of coprime positive integers. Therefore, except for the subcarrier position at position 0, the other subcarrier positions in the two sets do not overlap. Then, a set of subcarrier positions with non-uniform distribution is obtained based on the two sets of locations. The transmitter determines the frequency domain position occupied by the sensing signal based on the non-uniformly distributed subcarrier positions.
[0189] The frequency domain pattern of the sensing signal provided by the subcarrier position set in this embodiment can achieve a large uniform degree of freedom in the Khatri-Rao subspace and avoid the receiver observing multiple mirror images of the channel impulse response.
[0190] In some embodiments of this disclosure, the first parameter may include:
[0191] First frequency domain spacing P;
[0192] The second frequency domain interval Q, where P and Q are a pair of coprime positive integers, and P is less than Q, for example P = 2, Q = 5;
[0193] Minimum frequency domain spacing K min K min It is a positive integer. This minimum frequency domain spacing can also be called the minimum subcarrier spacing.
[0194] In some embodiments, the minimum frequency domain spacing K min It can be predefined by the protocol.
[0195] In some embodiments, K min ∈{2,4,6,12}.
[0196] In some embodiments, the transmitter can be based on the calculation formula q*P*K min By taking integer values from 0 to Q-1 for the variable q, we obtain the first set of positions, and then calculate p*Q*K based on this set. min By taking integers from 1 to 2P-1 for the variable p, we obtain the second position set.
[0197] It can be understood that each number in the first and second position sets indicates a subcarrier position in the OFDM (Orthogonal Frequency Division Multiplexing) system.
[0198] 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 second position set indicates the number of subcarrier positions as 2P-1, and the subcarrier frequency domain spacing is Q*K. min .
[0199] The set of subcarrier locations can be represented as:
[0200] {q*P*K min |q=0,1,…,Q-1}∪{p*Q*K min |p=1,2,…,2P-1}
[0201] For example, suppose K min If P is 2, P is 5, and Q is 7, then:
[0202] The first position set is {0,10,20,30,40,50,60};
[0203] The second set of positions is {14,28,42,56,70,84,98,112,126}.
[0204] 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 be based on the calculation formula q*P*K. min By taking integers from 1 to Q-1 for the variable q, we obtain the first set of positions, and then calculate p*Q*K based on this set. min By taking integers from 0 to 2P-1 for the variable p, we 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. minThe second position set indicates the number of subcarrier positions as 2P, and the subcarrier frequency domain spacing is Q*K. min .
[0207] The set of subcarrier locations can be represented as:
[0208] {q*P*K min |q=1,2,…,Q-1}∪{p*Q*K min |p=0,1,2,…,2P-1}
[0209] For example, suppose K min If P is 2, P is 5, and Q is 7, then:
[0210] The first set of positions is {10, 20, 30, 40, 50, 60};
[0211] The second set of positions is {0,14,28,42,56,70,84,98,112,126}.
[0212] The subcarrier position set is {0,10,14,20,28,30,40,42,50,56,60,70,84,98,112,126}.
[0213] In other embodiments, the transmitter can be based on the calculation formula q*P*K. min By taking integer values from 0 to Q-1 for the variable q, we obtain the first set of positions, and then calculate p*Q*K based on this set. min By taking integers from 0 to 2P-1 for the variable p, we obtain the second position set.
[0214] 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 second position set indicates the number of subcarrier positions as 2P, and the subcarrier frequency domain spacing is Q*K. min .
[0215] The set of subcarrier locations can be represented as:
[0216] {q*P*K min |q=0,1,2,…,Q-1}∪{p*Q*K min |p=0,1,2,…,2P-1}
[0217] For example, suppose K min If P is 2, P is 5, and Q is 7, then:
[0218] The first position set is {0,10,20,30,40,50,60};
[0219] The second set of positions is {0,14,28,42,56,70,84,98,112,126}.
[0220] The subcarrier position set is {0,10,14,20,28,30,40,42,50,56,60,70,84,98,112,126}.
[0221] According to the above technical solution, the frequency domain pattern of the sensing signal provided by the subcarrier position set in this embodiment can reduce the resource overhead and total transmission power of the sensing signal, and can achieve higher time domain resolution and higher sensing accuracy.
[0222] In other embodiments of this disclosure, the first parameter may further include at least one of the following:
[0223] Frequency domain offset k, where k is less than or equal to K min The frequency domain offset is a non-negative integer. This frequency domain offset can also be called the subcarrier offset. The frequency domain offset k is used to indicate the offset of the starting frequency domain (e.g., subcarrier) occupied by the sensed signal relative to the Nth frequency domain (e.g., subcarrier) in a PRB, where N is a non-negative integer, such as N can be 0.
[0224] The starting physical resource block (PRB) is numbered K0, where K0 is a non-negative integer. K0 represents 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 can be 0, and the Nth common resource block (CRB) can be CRB0. For example, if the starting PRB is numbered 2, it can indicate that the sensing signal is carried starting from the 2nd PRB relative to CRB0, that is, the PRB starting from the 24th resource element (RE) is used to indicate the carrying of the sensing signal.
[0225] In some embodiments, the transmitter can be based on the calculation formula q*P*K min +k, taking integer values from 0 to Q-1 for the variable q, obtains the first position set, and calculates based on the formula p*Q*K. min +k, taking integers from 1 to 2P-1 for variable p, to obtain the second position set.
[0226] 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 second position set indicates the number of subcarrier positions as 2P-1, and the subcarrier frequency domain spacing is Q*K. min .
[0227] The set of subcarrier locations can be represented as:
[0228] {q*P*K min+k|q=0,1,…,Q-1}∪{p*Q*K min +k|p=1,2,…,2P-1}
[0229] In other embodiments, the transmitter can be based on the calculation formula q*P*K. min +k, taking integers from 1 to Q-1 for the variable q, obtains the first position set, and calculates based on the formula p*Q*K. min +k, taking integers from 0 to 2P-1 for variable p, to obtain the second position set.
[0230] 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 second position set indicates the number of subcarrier positions as 2P, and the subcarrier frequency domain spacing is Q*K. min .
[0231] The set of subcarrier locations can be represented as:
[0232] {q*P*K min +k|q=1,2,…,Q-1}∪{p*Q*K min +k|p=0,1,2,…,2P-1}
[0233] In other embodiments, the transmitter can be based on the calculation formula q*P*K. min +k, taking integer values from 0 to Q-1 for the variable q, obtains the first position set, and calculates based on the formula p*Q*K. min +k, taking integers from 0 to 2P-1 for variable p, 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 second position set indicates the number of subcarrier positions as 2P, and the subcarrier frequency domain spacing is Q*K. min .
[0235] The set of subcarrier locations can be represented as:
[0236] {q*P*K min +k|q=0,1,2,…,Q-1}∪{p*Q*K min +k|p=0,1,2,…,2P-1}
[0237] It is understandable that subcarrier conflicts between different sensing links or communication networks can be avoided by flexibly setting the value of k.
[0238] In some embodiments, the transmitter can be based on the calculation formula q*P*K min+k+K0, taking integer values from 0 to Q-1 for the variable q, obtains the first position set, and then calculates p*Q*K based on the formula. min +k, taking integers from 1 to 2P-1 for variable p, to obtain the second position set.
[0239] 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 second position set indicates the number of subcarrier positions as 2P-1, and the subcarrier frequency domain spacing is Q*K. min .
[0240] The set of subcarrier locations can be represented as:
[0241] {q*P*K min +k+K0|q=0,1,…,Q-1}∪{p*Q*K min +k+K0|p=1,2,…,2P-1}
[0242] In other embodiments, the transmitter can be based on the calculation formula q*P*K. min +k+K0, taking integer values from 1 to Q-1 for the variable q, obtains the first position set, and calculates based on the formula p*Q*K. min +k+K0, taking integers from 0 to 2P-1 for variable p, to obtain the second position set.
[0243] 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 second position set indicates the number of subcarrier positions as 2P, and the subcarrier frequency domain spacing is Q*K. min .

[0247] 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. minThe second position set indicates the number of subcarrier positions as 2P, and the subcarrier frequency domain spacing is Q*K. min .
[0248] The set of subcarrier locations can be represented as:
[0249] {q*P*K min +k+K0|q=0,1,2,…,Q-1}∪{p*Q*K min +k+K0|p=0,1,2,…,2P-1}
[0250] It is understandable that subcarrier conflicts between different sensing links or communication networks can be avoided by flexibly setting the values of k and K0.
[0251] In some embodiments of this disclosure, the time domain location occupied by the sensing signal can be a first time domain location, which can be a time domain location specified by a protocol or a time domain location pre-negotiated between the transmitting end and the receiving end.
[0252] For example, the first time-domain position could be the Nth symbol position of each time slot, where N can be any non-negative integer, such as any non-negative integer between 0 and 13. N could be 5, or N could be both 5 and 9.
[0253] For example, the first time domain position can be the Nth symbol position of each even-numbered time slot, such as the Nth symbol position of the 0th time slot.
[0254] For example, the first time-domain position can be the Nth symbol position of each odd-numbered time slot, such as the Nth symbol position of the first time slot.
[0255] For example, the first time-domain position can be the Nth symbol position of a specific time slot among multiple time slots, and this specific time slot can be one of the multiple time slots according to S. offset A defined time slot. For example, every T slot The Sth time slot offset The position of the Nth symbol in the time slot. When T slot =3 and S offset When = 1, the position of the first time slot is the Nth symbol position of the first time slot in every 3 time slots.
[0256] For example, the first time-domain position can be the Nth symbol position of the Mth time slot in each subframe. Here, M can be 0 or 1, and N can be any non-negative integer between 0 and 13.
[0257] For example, the first time-domain position can be the Nth symbol position of the Mth time slot in the Pth subframe of each frame. Here, P can be any non-negative integer between 0 and 9, M can be 0 or 1, and N can be any non-negative integer between 0 and 13.
[0258] It should be noted that the first time domain location can be any time domain location specified in the agreement or negotiated in advance.
[0259] In some embodiments of this disclosure, the first time-domain position described above may be a time-domain position determined according to the first parameter.
[0260] The first parameter may also include at least one of the following:
[0261] A time-domain symbol number set L is used to determine the time-domain symbols within a time slot. For example, L = {5, 9} is used to indicate that the 5th and 9th symbols within a time slot are used to carry sensing signals.
[0262] Time-domain period T slot The T slot T is a positive integer; slot It can be used to determine the number of time slots contained in a period. Each time-domain period T slot At least one time slot can be used to carry sensing signals.
[0263] Time slot offset S offset The S offset For less than T slot A non-negative integer; this is used for time slot offset to determine the position of the time slot carrying the sensing signal within a time domain period, for example, T. slot For 2, S offset If the value is 0, it means that each time domain period contains 2 time slots, numbered 0 and 1 respectively. The 0th time slot is used to carry the sensing signal, while the 1st time slot does not carry the sensing signal.
[0264] The starting time slot number S0 is a non-negative integer; this starting time slot number S0 is used to determine the number of the starting time slot for carrying sensing signals. For example, if the starting time slot number S0 is 6, it means that the starting time slot for carrying sensing signals is numbered 6, and a time slot contains 14 symbols, that is, the time slot starting from the 84th symbol is used to carry sensing signals.
[0265] Number of time slots S num The S num A positive integer. Used to indicate the number of repetitions of the time-domain period. For example, the number of time slots S num If the value is 3, it means that the total number of time slots used to carry the sensing signals is 3.
[0266] In some embodiments, the L and T mentioned above slot S offset S0 and S num At least one of the following can be used to determine the time-domain location occupied by the sensed signal, and the time-domain location information can be the symbol location.
[0267] In some embodiments of this disclosure, the first parameter may include at least one of the following:
[0268] Rate matching pattern type indicator (patentType), for example, the rate matching pattern type indicator can be a coprime integer type (Coprime);
[0269] First frequency domain spacing P;
[0270] Second frequency domain spacing Q;
[0271] Minimum frequency domain spacing K min ;
[0272] Frequency domain offset k;
[0273] The initial physical resource block (PRB) number is K0;
[0274] Time-domain symbol number set L;
[0275] Time-domain period T slot ;
[0276] Time slot offset S offset ;
[0277] Start time slot number S0;
[0278] Number of time slots S num .
[0279] Figure 2 B is a schematic diagram illustrating resource occupancy of a sensing signal according to an embodiment of this disclosure. For example... Figure 2 As shown in Figure B, 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 particle (RE). Black-filled rectangular grids represent resource particles used to carry sensing signals (i.e., the first radio resource occupied by the sensing signal), while unfilled rectangular grids represent resource particles not used to carry sensing signals (i.e., the second radio resource not occupied by the sensing signal).
[0280] It should be noted that, Figure 2 The schematic diagram of resource occupancy of the sensing signal shown in B can also be called the schematic diagram of resource occupancy of the sensing signal based on the coprime integer pattern. Figure 2 The sensing signal shown in B can be the resource occupied by the sensing signal, determined based on a first parameter. This first parameter can be:
[0281] The rate matching pattern type indicator (pattenType) is a coprime integer type (Coprime);
[0282] The first frequency domain spacing P is 2;
[0283] The second frequency domain spacing Q is 5;

[0289] Time slot offset S offset =0;
[0290] The initial time slot number S0 is 6;
[0291] Number of time slots S num The value is 3.
[0292] Step S2103: The transmitter sends the first parameter to the receiver.
[0293] 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. As another example, the receiving end may also receive the first parameter sent by another entity.
[0294] In some embodiments, the transmitter may send a first message, which may include the first parameter described above. For example, the transmitter may send the first message to the receiver. Optionally, the receiver may receive the first message.
[0295] In one implementation, the transmitting end is a network device and the receiving end is a terminal device, and the first message can 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 can be an RRC message.
[0296] In another implementation, both the transmitter and receiver are terminal devices, and the first message can be a direct link RRC message, which can be an RRC message from the PC5 interface. For example, when both the transmitter and receiver are terminal devices, the first message can be an RRC message.
[0297] In other embodiments, the transmitter may send a second message, which may include one or more second parameters; the transmitter may also send indication information, which may be used to instruct the receiver to determine the first parameter from the one or more second parameters.
[0298] Similarly, the receiving end can receive a second message to obtain one or more second parameters, and the receiving end can also receive indication information to determine the first parameter from the one or more second parameters based on the indication information.
[0299] In some embodiments, the one or more second parameters may include the first parameter.
[0300] In some embodiments, the name of the second parameter is not limited, and may be, for example, "rate matching pattern", "rate matching mode", "rate matching parameter", "RateMatchPattern", "rate matching pattern based on coprime integers", "RateMatchPattern-Coprime", "sensing reference signal pattern", "sensing signal resource determination parameter", etc.
[0301] For example, one of the aforementioned second parameters can be an RMP (RateMatchPattern), and one or more of the aforementioned second parameters can form an RMP set. One or more RMPs can be identified as the first parameter from this RMP set through indication information.
[0302] For example, the transmitter can carry multiple second parameters (e.g., RMP1, RMP2, RMP3, etc.) through a second message (e.g., RRC message or Sidelink RRC message). The number of the second parameter (e.g., 1, 2 or 3) can be indicated by indication information (e.g., DCI), and the second parameter corresponding to the number can be used as the first parameter.
[0303] In one implementation, the transmitting end is a network device and the receiving end is a terminal device, and the second message can be an RRC message. For example, when the transmitting end is a network device and the receiving end is a terminal device, the second message can be an RRC message.
[0304] Optionally, the aforementioned indication information may be Downlink Control Information (DCI).
[0305] In another implementation, both the transmitter and receiver are terminal devices, and the second message can be a direct link RRC message, which can be an RRC message of the PC5 interface. For example, when both the transmitter and receiver are terminal devices, the second message can be an RRC message.
[0306] Optionally, the above-mentioned indication information may be Sidelink Control Information (SCI).
[0307] Step S2104: The receiving end determines the first radio resource occupied by the sensing signal.
[0308] In some embodiments, the receiving end may determine the first wireless resource occupied by the sensing signal based on the first parameter described above.
[0309] It should be noted that the specific method by which the receiving end determines the first wireless resource occupied by the sensing signal based on the first parameter can be referred to the description of the transmitting end determining the first wireless resource occupied by the sensing signal based on the first parameter in step S2102, and will not be repeated here.
[0310] Step S2105: The transmitting end transmits communication signals through the second wireless resource, which does not include the first wireless resource.
[0311] In some embodiments, the receiving end may receive communication signals through a second wireless resource.
[0312] Similarly, the second radio resource may include at least one RE, at least one REG, at least one RB, or at least one RBG.
[0313] In some embodiments, the first radio resource and the second radio resource can both be at least one resource particle (RE). The first radio resource and the second radio resource are different.
[0314] In some embodiments, the transmitter may map communication signals (e.g., data payload, wireless communication reference signal, etc.) onto a second wireless resource and transmit them.
[0315] For example, the transmitter can map the communication signal onto a resource particle that is not occupied by the sensing signal and send it.
[0316] In some embodiments, the receiver may determine the first radio resource occupied by the sensing signal based on the first parameter, for example, the coordinate position of the first radio resource on the time-frequency two-dimensional resource grid.
[0317] When receiving communication signals, the receiving end can perform rate matching. For example, it can skip the first radio resource and not receive communication signals; or it can receive communication signals through a second radio resource other than the first radio resource.
[0318] The methods involved in the embodiments of this disclosure may include at least one of the steps S2101 to S2105 described above. For example, step S2102 may be implemented as an independent embodiment, step S2104 may be implemented as an independent embodiment, step S2105 may be implemented as an independent embodiment, step S2102+S2105 may be implemented as an independent embodiment, step S2103+S2104 may be implemented as an independent embodiment, step S2102+S2103+S2105 may be implemented as an independent embodiment, and step S2103+S2104+S2105 may be implemented as an independent embodiment, but are not limited thereto.
[0319] In some embodiments, steps S2101 to S2105 can be performed in different orders or simultaneously. For example, steps S2102 and S2103 can be performed in different orders or simultaneously, and steps S2102 and S2104 can be performed in different orders or simultaneously.

[0322] By using the above method, in the integrated sensing and communication IC scenario, rate matching can be performed based on the first wireless resource occupied by the sensing signal, avoiding the sensing signal from affecting the transmission of the communication signal, thereby improving the transmission reliability of the communication signal in the integrated sensing and communication scenario.

[0433] In some embodiments, the above methods may include the methods described in the embodiments of the communication system, receiver, transmitter, etc., which will not be repeated here.
[0434] Figure 6 This is a schematic flowchart illustrating a signal transmission method according to an embodiment of the present disclosure. Figure 6 As shown, this disclosure relates to a signal transmission method, which can be executed by a communication system and may include:
[0435] Step S6101: Determine the first parameter.
[0436] In some embodiments, to indicate that the resource particles occupied by the sensing reference signal based on the coprime integer pattern are unavailable for the wireless communication system, a new rate matching pattern or a new RRC cell is defined based on a first parameter. For example, a new patternType is defined in the RateMatchPattern of the 3GPP protocol, or a new RRC cell RateMatchPattern-Coprime is defined in the 3GPP protocol.
[0437] The first parameter may include at least one of the following parameters:
[0438] Rate matching pattern type indicator (patentType), for example, the rate matching pattern type indicator can be a coprime integer type (Coprime);
[0439] First frequency domain spacing P;
[0440] Second frequency domain spacing Q;
[0441] Minimum frequency domain spacing K min ;
[0442] Frequency domain offset k;
[0443] The initial physical resource block (PRB) number is K0;
[0444] Time-domain symbol number set L;
[0445] Time-domain period T slot ;
[0446] Time slot offset S offset ;
[0447] Start time slot number S0;
[0448] Number of time slots S num .
[0449] Step S6102: The transmitter sends the first parameter.
[0450] The transmitting end (e.g., a wireless transmitter) generates a rate matching pattern (e.g., a first parameter) based on the sensing reference signal pattern and notifies the receiving end (e.g., a wireless communication receiver) of it via signaling.
[0451] In some embodiments, if the transmitting end is a network device (e.g., a base station) and the receiving end is a terminal device, then the above signaling is RRC signaling.
[0452] Optionally, the transmitter or wireless communication network can configure multiple RMPs via RRC signaling to form an RMP set. The transmitter can then dynamically select a subset (containing one or more RMPs) from the RMP set via DCI signaling and instruct it to the receiver.
[0453] In other embodiments, if both the transmitter and receiver are terminal devices, the RMP can be indicated by RRC signaling of the PC5 interface.
[0454] Step S6103: The transmitting end sends a communication signal.
[0455] For example, the transmitter maps communication signals (including data payloads and wireless communication reference signals, etc.) onto resource particles other than the sensing reference signal (indicated by the rate matching pattern described in 1) and transmits them.
[0456] Step S6104: The receiving end determines the resource particles occupied by the sensing signal.
[0457] For example, the receiver can receive the rate matching pattern (e.g., the first parameter) and determine the coordinate position of the resource particles occupied by the sensing reference signal on the time-frequency two-dimensional resource grid based on the rate matching pattern.
[0458] Step S6104: The receiving end receives the communication signal.
[0459] For example, when the receiving end receives wireless communication data, it performs rate matching on the resource particles described in section 4, that is, it skips the resource particles occupied by the sensing reference signal and does not receive wireless communication signals.
[0460] In some embodiments, in a sensing system, the sensing reference signal employs a pattern based on coprime integers, such as... Figure 2 As shown in Figure B, the transmitter generates a rate matching pattern as follows and notifies the receiver (e.g., a wireless communication receiver) via RRC signaling. When performing resource mapping, the transmitter performs rate matching based on this rate matching pattern. Correspondingly, the receiver receives the rate matching pattern and determines the coordinates of the resource particle occupied by the sensing reference signal on the time-frequency two-dimensional resource grid. When receiving communication data, the receiver skips the resource particle, i.e., it does not detect the received signal on the resource particle.
[0461] In some embodiments of this disclosure, a communication system is provided, which may include a receiver and a transmitter. The receiver may execute the signal transmission method performed by the receiver in the foregoing embodiments of this disclosure, and the transmitter may execute the signal transmission method performed by the transmitter in the foregoing embodiments of this disclosure.
[0462] This disclosure also provides embodiments of an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the receiving end in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by the transmitting end in any of the above methods.
[0463] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an Application-Specific Integrated Circuit (ASIC), and the functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), which can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.
[0464] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a Graphics Processing Unit (GPU) (which can be understood as a microprocessor), or a Digital Signal Processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using 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 and configuring the hardware circuit 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 hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).
