[0136] As a new technology in 5G and / or 6G (mainly 6G), ISAC technology aims to integrate sensing capability into the design of communication systems, so that the communication system can provide sensing as a service to users together with communication services. ISAC technology can be applied to scenarios such as base station self-transmission and self-reception, base station A transmission and base station B reception, terminal transmission and base station reception, base station transmission and terminal reception, terminal self-transmission and self-reception, terminal A transmission and terminal B reception, etc. In the design process of the ISAC system, the business requirements of communication and sensing need to be considered at the same time.

[0137] FIG. 1B is a schematic diagram of a sensing scenario, according to an embodiment of the present disclosure.

[0138] As shown in FIG. 1B, the sensing scenario can include, but is not limited to, the following six scenarios.

[0139] Scenario 1: Base station self-transmission and self-reception (or gNB self-transmission and self-reception, i.e., TRP monostatic). The base station transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the same base station receives and measures the reflected / scattered wave.

[0140] Scenario 2: Base station A transmission and base station B reception (or gNB A transmission and B reception, i.e., TRP-TRP bistatic). Base station A transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, base station B receives and measures the reflected / scattered wave.

[0141] Scenario 3: Terminal transmission and base station reception (or UE transmission and gNB reception, i.e., UE-TRP bistatic). The terminal transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the base station receives and measures the reflected / scattered wave.

[0142] Scenario 4: Base station transmission and terminal reception (or gNB transmission and UE reception, i.e., TRP-UE bistatic). The base station transmits a sensing signal, and after the sensing signal is reflected by the measured object, the terminal receives and measures the reflected / scattered wave.

[0143] Scenario 5: Terminal self-transmission and self-reception (or UE self-transmission and self-reception, i.e., UE monostatic). The terminal transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the same terminal receives and measures the reflected / scattered wave.

[0144] Scenario 6: Terminal A transmission and terminal B reception (or UE A transmission and B reception, i.e., UE-UE bistatic). Terminal A transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, terminal B receives and measures the reflected / scattered wave.

[0145] FIG. 1C is a schematic diagram of a sensing scenario, according to an embodiment of the present disclosure. FIG. 1D is a schematic diagram of another sensing scenario, according to an embodiment of the present disclosure.

[0146] In a network environment, when a terminal device transmits a sensing reference signal (S-RS) based on UE monostatic sensing, taking FIG. 1C as an example, for a target with a shorter distance, the S-RS propagation path is relatively shorter; for a target with a longer distance, the S-RS propagation path is relatively longer. In another scenario, the terminal device is under the coverage of a base station device, and transmits an S-RS based on TRP-UE bistatic sensing, taking FIG. 1D as an example, for a position closer to the cell center, that is, closer to the base station device, the S-RS propagation path is relatively shorter; for a target farther away from the base station device, the S-RS propagation path is relatively longer.

[0147] Therefore, in actual sensing services, the UE or the TRP may exist sensing for targets with different distances, which can cause different lengths of the propagation path of the sensing signal. On the premise of maintaining sensing accuracy, different lengths of a cyclic prefix (CP) are suitable for different sensing distances. For a long CP, better anti-time delay expansion and anti-multipath interference capabilities can be provided, which means that the device can sense targets with a farther distance. In addition, from the perspective of combining sensing and communication, the sensitivity of communication and sensing to the CP is different, and the distance of the propagation path of the communication signal and the propagation path of the sensing signal is not always the same. Therefore, in the related art, the mechanism of uniformly configuring the CP in the same time slot cannot meet the new integrated sensing and communication requirements.

[0148] Therefore, the embodiments of the present disclosure provide a communication method, a terminal determines the distribution of a CP corresponding to each time domain symbol in a first time domain resource, and transmits and / or receives a sensing signal through the first time domain resource, which can improve the transmission and / or reception efficiency of the sensing resource, thereby improving the sensing communication efficiency.

[0149] FIG. 2A is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiments of the present disclosure relate to a communication method, and the method includes:

[0150] In step S2101, the network device 102 transmits first information to the terminal 101.

[0151] In some embodiments, the terminal 101 receives the first information transmitted by the network device 102.

[0152] In some embodiments, the first information is used to determine the first time domain resource.

[0153] In some embodiments, the first information may, for example, be configuration information of the first time domain resource, and the configuration information may be CP configuration information, which may include at least one of a CP type and a CP length.

[0154] In some embodiments, the first time domain resource can be configured by the network device 102, and the first time domain resource can include at least one time domain symbol, which can be continuous time domain symbols or non-continuous time domain symbols.

[0155] In step S2102, the terminal 101 determines the first time domain resource.

[0156] The first time domain resource includes at least one time domain symbol, each of the at least one time domain symbol includes a cyclic prefix (CP), and the first time domain resource is used for transmission of the sensing signal. The transmission can include sending and / or receiving. The first time domain resource used for transmission of the sensing signal can be that the first time domain resource is used for sending and / or receiving the sensing signal. That is, the first time domain resource can be used for sending the sensing signal, the first time domain resource can also be used for receiving the sensing signal, and the first time domain resource can also be used for both sending and receiving the sensing signal.

[0157] In some embodiments, the terminal 101 can determine the distribution of each time domain symbol in the first time domain resource and the distribution of the CP in each time domain symbol according to the first information sent by the network device 102.

[0158] In some embodiments, the terminal 101 can determine the distribution of each time domain symbol in the first time domain resource and the distribution of the CP in each time domain symbol based on a protocol predefinition.

[0159] In some embodiments, the network device 102 can indicate the CP type, and the terminal 101 determines the distribution of each time domain symbol in the first time domain resource and the distribution of the CP in each time domain symbol according to the CP type indicated by the network device 102 and the protocol predefinition.

[0160] In exemplary embodiments, the CP types of the CP in each time domain symbol are the same or different.

[0161] In some embodiments, each time domain symbol can include CPs of the same type or different types, and the CP types can be, for example, normal CP (NCP), extended CP (ECP), long CP (LCP), extended long CP (ELCP), etc. In the same time domain symbol under the same SCS condition, the length relationship corresponding to different CP types is: NCP < ECP < LCP < ELCP.

[0162] In some embodiments, the CP type and / or the CP length can be configured / indicated by the network device or determined based on a protocol predefinition.

[0163] In some embodiments, the network device can directly indicate the CP type, or indicate the CP pattern of a continuous time domain symbol.

[0164] For example, the network device indicates the CP type as NCP, and the terminal determines the CP of each time domain symbol in the first time domain resource as NCP when determining the first time domain resource.

[0165] For another example, the network device indicates the CP type as LCP, and the terminal determines the CP of each time domain symbol in the first time domain resource as LCP when determining the first time domain resource.

[0166] For another example, the first time domain resource includes 4 time domain symbols, and the network device indicates the CP pattern as 1010, where 1 represents NCP and 0 represents LCP. Then, 1010 represents that the CP of the first time domain symbol in the first time domain resource is NCP, the CP of the second time domain symbol is LCP, the CP of the third time domain symbol is NCP, and the CP of the fourth time domain symbol is LCP.

[0167] In exemplary embodiments, at least one of the following is determined based on a protocol predefinition or a network device configuration: the number of time domain symbols in the first time domain resource; the CP type of the CP; and the CP length of the CP.

[0168] In some embodiments, the number of time domain symbols in the first time domain resource is determined based on a protocol predefinition or a network device configuration.

[0169] In some embodiments, the number of time domain symbols in the first time domain resource is predefined based on a protocol.

[0170] In other embodiments, the number of time domain symbols in the first time domain resource is configured based on a network device, and the network device indicates the number to the terminal.

[0171] In some embodiments, the number of time domain symbols in the first time domain resource can be represented by M, where M is a positive integer. For example, M can be 4, 6, etc.

[0172] In some embodiments, the first time domain resource can include one or more first time units. For a first time unit, a candidate set of time domain symbols can be predefined by a protocol, and the numbers in the candidate set are positive integers. For example, the candidate set of time domain symbols for a time slot is 16, 14, 12, 8, 6. The number of the candidate set can be configured / indicated to the terminal device by the network device through a first signaling. The first signaling includes one of DCI, RRC, MAC CE, etc.

[0173] In some embodiments, the CP type corresponding to the time domain symbol in the first time domain resource is determined based on a protocol predefinition or network device configuration. The CP type corresponding to the time domain symbol in the first time domain resource can be one or more.

[0174] In some embodiments, the CP length corresponding to the time domain symbol in the first time domain resource can be determined based on a protocol predefinition or network device configuration.

[0175] In the embodiments of the present disclosure, the first time domain resource can be one or more of FIGS. 2B-2Q. The first time domain resource in FIGS. 2B-2Q is described below, but the present disclosure is not limited thereto.

[0176] FIG. 2B is a schematic diagram of a first time domain resource according to an embodiment of the present disclosure, and FIG. 2C is a schematic diagram of another first time domain resource according to an embodiment of the present disclosure.

[0177] In an exemplary embodiment, the length of each time domain symbol in the at least one time domain symbol is the same, and the starting position of the CP in each time domain symbol is the same.

[0178] In the present embodiment, the first time domain resource includes a plurality of time domain symbols, the length of each time domain symbol is the same, and the length of each time domain symbol can be a preset value. The starting position of the CP in each time domain symbol is the same. For example, the starting position of the CP in each time domain symbol is aligned with the starting position of each time domain symbol.

[0179] In the present embodiment, the CP type included in each time domain symbol can be the same or different. The starting position of the different type of CP in the same time domain symbol is the same.

[0180] In one implementation, taking the first time domain resource including four consecutive time domain symbols (for example, symbol n-symbol n+3, where n is a positive integer) as an example, the CP length or CP type is indicated by the network device. When the CP is NCP, the first time domain resource is as shown in configuration 1 of FIG. 2B, that is, the starting position of the NCP in each symbol is aligned with the starting position of each symbol. When the CP is LCP, the first time domain resource is as shown in configuration 2 of FIG. 2B, that is, the starting position of the LCP in each symbol is aligned with the starting position of each symbol.

[0181] In an implementation, taking 4 continuous time domain symbols as an example, the CP length of the first time domain resource is indicated by the network device through the CP pattern. When the CP pattern is 1010 and 1 represents LCP and 0 represents NCP, the first time domain resource is as shown in FIG. 2C. That is, the CP of symbol n is NCP, the CP of symbol n+1 is LCP, the CP of symbol n+2 is NCP, and the CP of symbol n+3 is LCP. The starting position of the CP (NCP or LCP) in each symbol is aligned with the starting position of each symbol.

[0182] FIG. 2D is a schematic diagram of a first time domain resource according to an embodiment of the present disclosure, and FIG. 2E is a schematic diagram of another first time domain resource according to an embodiment of the present disclosure.

[0183] In an exemplary embodiment, the effective length of each time domain symbol is the same, and the ending position of the CP in each time domain symbol is the same.

[0184] The effective length of a time domain symbol refers to the length of the time domain symbol carrying valid information. The length of a time domain symbol is the sum of the effective length of the time domain symbol and the CP length.

[0185] In the present embodiment, the first time domain resource includes a plurality of time domain symbols, the effective length of each time domain symbol is the same, and the effective length of each time domain symbol can be a preset value. The ending position of the NCP is taken as the ending position of the CP in each time domain symbol when the starting position of the NCP is aligned with the starting position of the time domain symbol.

[0186] In the present embodiment, the CP type included in each time domain symbol can be the same or different. The ending position of different types of CP in the same time domain symbol is the same.

[0187] In an implementation, taking 4 continuous time domain symbols as an example, the CP length or CP type of the first time domain resource is indicated by the network device. When the CP is NCP, the first time domain resource is as shown in configuration 1 of FIG. 2D; when the CP is LCP, the first time domain resource is as shown in configuration 2 of FIG. 2D; wherein the ending position of each CP in configuration 1 of FIG. 2D is the same as the ending position of each CP in configuration 1, which is the ending position of the NCP when the starting position of the NCP is aligned with the starting position of the time domain symbol.

[0188] In an implementation, taking 4 continuous time domain symbols as an example, the CP length of the first time domain resource is indicated by the network device through the CP pattern. When the CP pattern is 1010, and 1 represents LCP and 0 represents NCP, the first time domain resource is as shown in FIG. 2E. That is, the CP of symbol n is NCP, the CP of symbol n+1 is LCP, the CP of symbol n+2 is NCP, and the CP of symbol n+3 is LCP. The ending position of the CP (NCP or LCP) in each symbol is the same.

[0189] In an example embodiment, the sum of the effective length of each time domain symbol and the CP length of each time domain symbol is greater than the length of each time domain symbol, and the CP in each time domain symbol partially overlaps with the previous time domain symbol of the time domain symbol.

[0190] In the embodiment, the first time domain resource includes a plurality of time domain symbols, the effective length of each time domain symbol is the same, and the ending position of the different types of CP in the same time domain symbol is the same. For a time domain symbol, when the sum of the effective length of the time domain symbol and the CP length is greater than the length of a time domain symbol, the CP of the time domain symbol partially overlaps with the previous time domain symbol.

[0191] In an implementation, the first time domain resource is 4 continuous time domain symbols. When the CP is NCP, the first time domain resource is as shown in configuration 1 of FIG. 2D. At this time, the sum of the effective length of the time domain symbol and the NCP length is equal to the length of the time domain symbol. When the CP is LCP, the first time domain resource is as shown in configuration 2 of FIG. 2D. At this time, the sum of the effective length of the time domain symbol and the LCP length is greater than the length of the time domain symbol, and the LCP of the time domain symbol partially overlaps with the previous time domain symbol of the time domain symbol. For example, the LCP in symbol n+1 partially overlaps with symbol n.

[0192] In an implementation, taking 4 continuous time domain symbols as an example, the CP pattern is 1010, and 1 represents LCP and 0 represents NCP. The first time domain resource is as shown in FIG. 2E. That is, the CP of symbol n is NCP, the CP of symbol n+1 is LCP, the CP of symbol n+2 is NCP, and the CP of symbol n+3 is LCP. The LCP of symbol n+1 partially overlaps with symbol n, and the LCP of symbol n+3 partially overlaps with symbol n+2.

[0193] FIG. 2F is a schematic diagram of a first time domain resource according to an embodiment of the present disclosure, and FIG. 2G is a schematic diagram of another first time domain resource according to an embodiment of the present disclosure.

[0194] In an example embodiment, the effective length of each time domain symbol is the same, the different time domain symbols are connected head to tail, and the total length of at least one time domain symbol is less than or equal to the length of the first time domain resource.

[0195] In the embodiment, the first time domain resource includes a plurality of time domain symbols, and the effective length of each time domain symbol is the same, and the effective length of each time domain symbol can be a preset value. Adjacent time domain symbols are connected end to end, and the total length of at least one time domain symbol included in the first time domain symbol is less than or equal to the length of the first time domain resource.

[0196] In the embodiment, when the sum of the effective length of all time domain symbols and the CP length is greater than the length of the first time domain resource, the first N time domain symbols (N is a positive integer) are preferentially mapped, and the sum of the effective length of the first N+1 time domain symbols and the CP length is greater than the length of the first time domain resource.

[0197] In one implementation, the first time domain resource is four continuous time domain symbols, the first time domain symbol and the second time domain symbol are connected end to end, the second time domain symbol and the third time domain symbol are connected end to end, and the third time domain symbol and the fourth time domain symbol are connected end to end. When the CP is NCP, the first time domain resource is as shown in configuration 1 of FIG. 2F, and at this time, the sum of the effective length of the four time domain symbols and the NCP length is equal to the length of the first time domain resource. When the CP is LCP, the first time domain resource is as shown in configuration 2 of FIG. 2F, and at this time, the sum of the effective length of the four time domain symbols and the LCP length is greater than the length of the first time domain resource, so the first three time domain symbols, i.e., symbol n, symbol n+1 and symbol n+2, are preferentially mapped, and symbol n+3 is discarded.

[0198] In one implementation, taking the first time domain resource as an example, the CP pattern is 1010, and 1 represents LCP and 0 represents NCP, and the first time domain resource is as shown in FIG. 2G. That is, the CP of symbol n is NCP, the CP of symbol n+1 is LCP, the CP of symbol n+2 is NCP, and the CP of symbol n+3 is LCP. At this time, the sum of the effective length of the four time domain symbols and the LCP length is greater than the length of the first time domain resource, so the first three time domain symbols, i.e., symbol n, symbol n+1 and symbol n+2, are preferentially mapped, and symbol n+3 is discarded.

[0199] FIG. 2H is a schematic diagram of a first time domain resource according to an embodiment of the present disclosure, and FIG. 2I is a schematic diagram of another first time domain resource according to an embodiment of the present disclosure.

[0200] In the exemplary embodiment, the effective length of each time domain symbol except the last time domain symbol in the at least one time domain symbol is the same, the different time domain symbols are connected end to end, and the end position of the last time domain symbol is aligned with the end position of the first time domain resource.

[0201] In the embodiment, the first time domain resource includes a plurality of time domain symbols, and the effective length of each time domain symbol except the last time domain symbol is the same, which can be a preset value. Adjacent time domain symbols are connected end to end, and the end position of the last time domain symbol and the end position of the first time domain resource are aligned by controlling the effective length of the last time domain symbol.

[0202] In the embodiment, when the sum of the effective length of all time domain symbols and the CP length is greater than the length of the first time domain resource, the first N time domain symbols (N is a positive integer) are preferentially mapped, and the sum of the effective length of the first N+1 time domain symbols and the CP length is greater than the length of the first time domain resource. The effective length of the first N-1 time domain symbols is the same as the effective length of the time domain symbol corresponding to the normal CP (for example, NCP), and the effective length of the Nth time domain symbol is greater than the effective length of the time domain symbol of the normal CP, and the end of the Nth time domain symbol is aligned with the end of the first time domain resource. Alternatively, the effective length of the Nth time domain symbol is still the same as the effective length of the time domain symbol of the normal CP, and the end of the Nth time domain symbol is aligned with the end of the first time domain resource by adding a cyclic postfix.

[0203] In one implementation, the first time domain resource is four continuous time domain symbols, the first time domain symbol is connected end to end with the second time domain symbol, the second time domain symbol is connected end to end with the third time domain symbol, and the third time domain symbol is connected end to end with the fourth time domain symbol. When the CP is NCP, the first time domain resource is as shown in configuration 1 of FIG. 2H, and at this time, the sum of the effective length of the four time domain symbols and the NCP length is equal to the length of the first time domain resource. When the CP is LCP, the first time domain resource is as shown in configuration 2 of FIG. 2H, and at this time, the sum of the effective length of the four time domain symbols and the LCP length is greater than the length of the first time domain resource, so the first three time domain symbols, i.e., symbol n, symbol n+1 and symbol n+2, are preferentially mapped, and symbol n+3 is discarded. Moreover, the end position of symbol n+2 is aligned with the end position of the first time domain resource by lengthening the effective length of symbol n+2 or adding a cyclic postfix.

[0204] In one implementation, taking the first time domain resource as an example of four continuous time domain symbols, the CP pattern is 1010, and 1 represents LCP and 0 represents NCP, the first time domain resource is as shown in FIG. 2G. That is, the CP of symbol n is NCP, the CP of symbol n+1 is LCP, the CP of symbol n+2 is NCP, and the CP of symbol n+3 is LCP, and at this time, the sum of the effective length of the four time domain symbols and the LCP length is greater than the length of the first time domain resource, so the first three time domain symbols, i.e., symbol n, symbol n+1 and symbol n+2, are preferentially mapped, and symbol n+3 is discarded. Moreover, the end position of symbol n+2 is aligned with the end position of the first time domain resource by lengthening the effective length of symbol n+2 or adding a cyclic postfix.

[0205] FIG. 2J is a schematic diagram of a first time-domain resource according to an embodiment of the present disclosure, and FIG. 2K is a schematic diagram of another first time-domain resource according to an embodiment of the present disclosure.

[0206] In an example embodiment, the effective length of each time-domain symbol is the same, adjacent time-domain symbols are connected end to end, and the end position of the last time-domain symbol is aligned with the end position of the first time-domain resource.

[0207] In the present embodiment, the first time-domain resource includes a plurality of time-domain symbols, and the effective length of each time-domain symbol is the same, which can be calculated according to the length of the first time-domain resource and the CP length. Adjacent time-domain symbols are connected end to end, and the effective length of the time-domain symbol is scaled to make the end position of the last time-domain symbol aligned with the end position of the first time-domain resource.

[0208] In the present embodiment, when the sum of the effective length of all time-domain symbols and the CP length is greater than the length of the first time-domain resource, the first N time-domain symbols (N is a positive integer) are preferentially mapped, and the sum of the effective length of the first N+1 time-domain symbols and the CP length is greater than the length of the first time-domain resource. The effective length of the first N time-domain symbols is the same, and the end point of the Nth time-domain symbol is aligned with the end point of the first time-domain resource.

[0209] In one implementation, the first time-domain resource is four continuous time-domain symbols, the first time-domain symbol is connected end to end with the second time-domain symbol, the second time-domain symbol is connected end to end with the third time-domain symbol, and the third time-domain symbol is connected end to end with the fourth time-domain symbol. When the CP is NCP, the first time-domain resource is as shown in configuration 1 of FIG. 2J. When the CP is LCP, the first time-domain resource is as shown in configuration 2 of FIG. 2J. At this time, the sum of the effective length of the four time-domain symbols and the LCP length is greater than the length of the first time-domain resource, so the first three time-domain symbols, i.e., symbol n, symbol n+1, and symbol n+2, are preferentially mapped, and symbol n+3 is discarded. And the effective length of the first three time-domain symbols is scaled to make the end position of symbol n+2 aligned with the end position of the first time-domain resource.

[0210] In an implementation, taking 4 time domain symbols as an example, the CP pattern is 1010, and 1 represents LCP and 0 represents NCP, the first time domain resource is as shown in FIG. 2K. That is, the CP of symbol n is NCP, the CP of symbol n+1 is LCP, the CP of symbol n+2 is NCP, and the CP of symbol n+3 is LCP. At this time, the sum of the effective length of 4 time domain symbols and the LCP length is greater than the length of the first time domain resource, the first 3 time domain symbols, i.e., symbol n, symbol n+1, and symbol n+2, are preferentially mapped, and symbol n+3 is discarded. Moreover, the effective length of the first 3 time domain symbols is scaled so that the end position of symbol n+2 is aligned with the end position of the first time domain resource.

[0211] In an example embodiment, the effective length of each time domain symbol is determined based on one of the following: the effective length of each time domain symbol is determined according to the length of the first time domain resource, the CP length of each time domain symbol, and the number of time domain symbols; the effective length of each time domain symbol is determined according to the length of the first time domain resource, the ratio of the CP length of each time domain symbol to the effective length of each time domain symbol, and the number of time domain symbols; and the effective length of each time domain symbol is determined according to the length of the first time domain resource, the ratio of the CP length of each time domain symbol to the length of each time domain symbol, and the number of time domain symbols.

[0212] In an implementation, the effective length of each time domain symbol is determined according to the length of the first time domain resource, the CP length of each time domain symbol, and the number of time domain symbols.

[0213] For example, the CP length is fixed, and the effective length of the time domain symbol is scaled according to the length of the first time domain resource and the number of mapped time domain symbols. The length of the first time domain resource is L, the number of mapped time domain symbols is M, and the CP length is G. Then, the effective length of the time domain symbol is (L-M*G) / M.

[0214] In an implementation, the effective length of each time domain symbol is determined according to the length of the first time domain resource, the ratio of the CP length of each time domain symbol to the effective length of each time domain symbol, and the number of time domain symbols.

[0215] For example, the CP length is fixed, and the effective length of the time domain symbol is scaled according to the length of the first time domain resource and the number of mapped time domain symbols. The length of the first time domain resource is L, the number of mapped time domain symbols is M, and the CP length is G. Then, the effective length of the time domain symbol is (L-M*G) / M.

[0216] In an implementation, the effective length of each time domain symbol is determined according to a length of the first time domain resource, a ratio of a CP length of each time domain symbol to a length of each time domain symbol, and a number of time domain symbols.

[0217] For example, the ratio of the CP length to the length of the time domain symbol is determined, and the effective length of the time domain symbol is scaled according to the length of the first time domain resource and the number of mapped time domain symbols. The length of the first time domain resource is L, the number of mapped time domain symbols is M, and the ratio of the CP length to the length of the time domain symbol is G. Then, the effective length of the time domain symbol is (L-L*G) / M.

[0218] In an example embodiment, the effective length of each time domain symbol is the same and is a first value, adjacent time domain symbols are connected end to end, and the end position of the last time domain symbol is aligned with the end position of the first time domain resource.

[0219] The first value can be a preset value, and the size of the first value is not limited in the present disclosure.

[0220] In the present embodiment, the first time domain resource includes a plurality of time domain symbols, the effective length of each time domain symbol is the same and is a preset value, and the preset value is, for example, the effective length of the time domain symbol corresponding to NCP, that is, the preset value of the effective length of the time domain symbol is obtained by using the length of the time domain symbol minus the length of NCP. Adjacent time domain symbols are connected end to end, and the end position of the last time domain symbol is aligned with the end position of the first time domain resource by adding a guard interval or scaling the CP length.

[0221] FIG. 2L is a schematic diagram of a first time domain resource according to an embodiment of the present disclosure, and FIG. 2M is a schematic diagram of another first time domain resource according to an embodiment of the present disclosure.

[0222] In an example embodiment, a guard interval exists between adjacent time domain symbols, and the length of the guard interval is determined based on the length of the first time domain resource and the length of each time domain symbol.

[0223] In the present embodiment, the length of each guard interval can be obtained by subtracting the total length of the plurality of time domain symbols from the length of the first time domain resource, and then dividing the obtained difference by the number of time domain symbols.

[0224] In the embodiment, when the sum of the effective length of all time domain symbols and the CP length is greater than the length of the first time domain resource, the first N time domain symbols (N is a positive integer) are preferentially mapped, and the sum of the effective length of the first N+1 time domain symbols and the CP length is greater than the length of the first time domain resource. The effective length of the first N time domain symbols is the same, and the end of the Nth time domain symbol is aligned with the end of the first time domain resource. A guard interval is included before each time domain symbol, and the length of the guard interval is (the length of the first time domain resource-the sum of the effective length of the first N time domain symbols and the length of the CP) / N, or the length of the guard interval is (the length of the first time domain resource-the length of the first N time domain symbols) / N.

[0225] In one implementation, the first time domain resource is 4 continuous time domain symbols, when the CP is NCP, the first time domain resource is as shown in configuration 1 of FIG. 2L. When the CP is LCP, the first time domain resource is as shown in configuration 2 of FIG. 2L, at this time, the sum of the effective length of the 4 time domain symbols and the LCP length is greater than the length of the first time domain resource, then the first 3 time domain symbols, i.e., symbol n, symbol n+1 and symbol n+2, are preferentially mapped, and symbol n+3 is discarded. And by adding a guard interval before each time domain symbol, the end position of symbol n+2 is aligned with the end position of the first time domain resource.

[0226] In one implementation, taking the first time domain resource as an example, the first time domain resource is 4 continuous time domain symbols, the CP pattern is 1010, and 1 represents LCP and 0 represents NCP, the first time domain resource is as shown in FIG. 2M. That is, the CP of symbol n is NCP, the CP of symbol n+1 is LCP, the CP of symbol n+2 is NCP, and the CP of symbol n+3 is LCP, at this time, the sum of the effective length of the 4 time domain symbols and the LCP length is greater than the length of the first time domain resource, then the first 3 time domain symbols, i.e., symbol n, symbol n+1 and symbol n+2, are preferentially mapped, and symbol n+3 is discarded. And by adding a guard interval before each time domain symbol, the end position of symbol n+2 is aligned with the end position of the first time domain resource.

[0227] FIG. 2N is a schematic diagram of a first time domain resource according to an embodiment of the present disclosure, and FIG. 2O is a schematic diagram of another first time domain resource according to an embodiment of the present disclosure.

[0228] In the exemplary embodiment, the CP length of each time domain symbol is determined based on the length of the first time domain resource and the effective length of each time domain symbol.

[0229] In the embodiment, the first time domain resource includes a plurality of time domain symbols, each time domain symbol has a same effective length and a preset value, and a CP length of each time domain symbol can be calculated according to a length of the first time domain resource and the effective length of each time domain symbol. Adjacent time domain symbols are connected end to end, and the ending position of the last time domain symbol and the ending position of the first time domain resource are aligned by scaling the CP length.

[0230] In the embodiment, when the sum of the effective length and the CP length of all time domain symbols is greater than the length of the first time domain resource, the first N time domain symbols (N is a positive integer) are preferentially mapped, and the sum of the effective length and the CP length of the first N+1 time domain symbols is greater than the length of the first time domain resource. The effective lengths of the first N time domain symbols are the same, and the endpoint of the Nth time domain symbol is aligned with the endpoint of the first time domain resource. The CP of each time domain symbol includes an additional CP length, and the additional CP length = (the length of the first time domain resource - the sum of the effective lengths and the CP lengths of the first N time domain symbols) / N.

[0231] In one implementation, the first time domain resource is four continuous time domain symbols. When the CP is NCP, the first time domain resource is as shown in configuration 1 of FIG. 2N. When the CP is LCP, the first time domain resource is as shown in configuration 2 of FIG. 2N. At this time, the sum of the effective length and the LCP length of the four time domain symbols is greater than the length of the first time domain resource, so the first three time domain symbols, i.e., symbol n, symbol n+1 and symbol n+2, are preferentially mapped, and symbol n+3 is discarded. Moreover, the CP lengths of the first three time domain symbols are scaled so that the ending position of symbol n+2 and the ending position of the first time domain resource are aligned.

[0232] In one implementation, taking the first time domain resource as an example of four continuous time domain symbols, the CP pattern is 1010, and 1 represents LCP and 0 represents NCP. When the first time domain resource is as shown in FIG. 2K. That is, the CP of symbol n is NCP, the CP of symbol n+1 is LCP, the CP of symbol n+2 is NCP, and the CP of symbol n+3 is LCP. At this time, the sum of the effective length and the LCP length of the four time domain symbols is greater than the length of the first time domain resource, so the first three time domain symbols, i.e., symbol n, symbol n+1 and symbol n+2, are preferentially mapped, and symbol n+3 is discarded. Moreover, the CP lengths of the first three time domain symbols are scaled so that the ending position of symbol n+2 and the ending position of the first time domain resource are aligned.

[0233] In an example embodiment, the CP length is determined based on one of: the length of the first time domain resource, the effective length of each time domain symbol, and the number of time domain symbols; the length of the first time domain resource, the ratio of the CP length of each time domain symbol to the effective length of each time domain symbol, and the number of time domain symbols; and the length of the first time domain resource, the ratio of the CP length of each time domain symbol to the length of each time domain symbol, and the number of time domain symbols.

[0234] In one implementation, the CP length is determined based on the length of the first time domain resource, the effective length of each time domain symbol, and the number of time domain symbols.

[0235] For example, the CP length of each time domain symbol is scaled according to the length of the first time domain resource and the number of mapped time domain symbols, based on a percentage of the effective length of each time domain symbol. The length of the first time domain resource is L, the number of mapped time domain symbols is M, and the percentage of the effective length of each time domain symbol is G. The CP length is (L-M*G) / M.

[0236] In one implementation, the CP length is determined based on the length of the first time domain resource, the ratio of the CP length of each time domain symbol to the effective length of each time domain symbol, and the number of time domain symbols.

[0237] For example, the CP length of each time domain symbol is scaled according to the length of the first time domain resource and the number of mapped time domain symbols, based on a percentage of the length of each time domain symbol. The length of the first time domain resource is L, the number of mapped time domain symbols is M, and the percentage of the length of each time domain symbol is G. The CP length is (L*G) / (M+M*G).

[0238] In one implementation, the CP length is determined based on the length of the first time domain resource, the ratio of the CP length of each time domain symbol to the length of each time domain symbol, and the number of time domain symbols.

[0239] For example, the CP length of each time domain symbol is scaled according to the length of the first time domain resource and the number of mapped time domain symbols, based on a percentage of the length of each time domain symbol. The length of the first time domain resource is L, the number of mapped time domain symbols is M, and the percentage of the length of each time domain symbol is G. The CP length is (L*G) / M.

[0240] In an example embodiment, a first time domain symbol of the at least one time domain symbol is used for transmitting and / or receiving a sensing signal, and a CP of a next time domain symbol of the first time domain symbol is an extended CP.

[0241] In the embodiment, the sensing signal can be a sensing reference signal (sensing RS) for example. The first time domain symbol can be a time domain symbol in the first time domain resource for transmitting and / or receiving the sensing signal.

[0242] In the embodiment, the first time domain symbol refers to a time domain symbol in the first time domain resource for transmitting and / or receiving a sensing reference signal (sensing RS), and a CP of a next time domain symbol of the first time domain symbol can be set as an extension CP, so as to ensure that even if there is a multipath classification of a signal with large delay and high strength, no impact on communication is caused.

[0243] Suppose that a CP length of a general Orthogonal Frequency Division Multiplexing (OFDM) symbol is a normal CP, that is, NCP. An OFDM symbol of the first signal adds a long CP, that is, LCP. When a last time domain symbol of the first signal is carried by the nth symbol, a CP of an (n+1)th symbol is an extension CP. The first signal includes at least one of a sensing RS and a broadcast signal. The extension CP can be a CP extension added before the base CP, and a CP length after the extension can be equal to the LCP, that is, NCP+CP extension=LCP. Alternatively, the extension CP can be directly replaced by a longer CP (for example, NCP is replaced by LCP) from the base CP. Because the extension CP or the LCP is used, when a next OFDM symbol of the first signal is used for communication, even if there is a multipath classification of the first signal with large delay and high strength, no impact on communication is caused. In this way, because the extension CP or the LCP is added to the next OFDM symbol, an effective length of the OFDM symbol for transmitting the first channel is reduced.

[0244] FIG. 2P is a schematic diagram of a first time domain resource according to an embodiment of the present disclosure, and FIG. 2Q is a schematic diagram of another first time domain resource according to an embodiment of the present disclosure.

[0245] In some embodiments, the extension CP can be determined based on the manners shown in FIG. 2P or FIG. 2Q.

[0246] In one implementation, as shown in FIG. 2P, a long CP is added to the time domain symbol n+1 and the sensing RS is transmitted, and a CP extension is added before NCP of the symbol n+2 for protection of subsequent transmission.

[0247] In one implementation, as shown in FIG. 2Q, a long CP is added to the time domain symbol n+1 and the sensing RS is transmitted, and NCP is replaced by LCP of the symbol n+2 for protection of subsequent transmission.

[0248] In some embodiments, the CP of the n+1th time domain symbol can also be configured by the network device whether to be an extended CP.

[0249] In step S2103, the terminal 101 and the network device 102 transmit and / or receive the sensing signal based on the first time domain resource.

[0250] In some embodiments, the terminal 101 and the network device 102 can transmit the sensing signal based on the first time domain resource. For example, the terminal 101 transmits the sensing signal to the network device 102 based on the first time domain resource, and the network device 102 receives the sensing signal based on the first time domain resource.

[0251] In some embodiments, the terminal 101 and the network device 102 can transmit the sensing signal based on the first time domain resource.

[0299] In some embodiments, the above method can include the method of the embodiments of the above communication system side, terminal side, network device side, etc., which are not described herein again.

[0300] The embodiments of the present disclosure propose a communication method, in a network, the service types interacted between the network device and the terminal device include sensing service and communication service.

[0301] For sensing service, the network device and the terminal device jointly complete sensing signal transceiving, or the network device configures the first resource for the terminal device, the terminal device itself completes sensing signal transceiving, or the network device configures the first resource for the terminal device, and multiple terminal devices complete sensing signal transceiving. For communication service, the network device and the terminal device jointly complete communication signal transceiving.

[0302] The communication and / or sensing service is transmitted on the first time domain resource, which is configured by the network device. The first time domain resource includes at least one time domain symbol, which can be continuous time domain symbols or non-continuous time domain symbols. The time domain symbol contains different types of CPs, such as NCP, ECP, LCP, ELCP, etc. Under the condition of the same SCS, the same time domain symbol is NCP<ECP<LCP<ELCP. The type of the CP, or the length of the CP, is configured / indicated by the network device or determined based on a protocol predefined rule.

[0303] Further, the first time domain resource configuration includes CP related configuration, and the specific determination method includes one of the following methods 1 to 7.

[0304] Method 1:

[0305] The lengths of the time domain symbols in the first time domain resource are equal, that is, the lengths of the time domain symbols of different types of CPs are the same. The starting points of different types of CPs in the same time domain symbol are the same.

[0306] In one implementation, the first time domain resource is continuous 4 time domain symbols (for example, symbol n~symbol n+3, where n is a positive integer), and the CP length is explicitly indicated by the base station through network side signaling. When the CP is NCP, the first time domain resource is as shown in configuration 1 of FIG. 2B; when the CP is LCP, the first time domain resource is as shown in configuration 2 of FIG. 2B.

[0332] In some embodiments, communication and / or sensing services are transmitted on a first time-domain resource configured by a network device. The first time-domain resource includes at least one time-domain symbol, which can be continuous or non-continuous. The time-domain symbol contains different types of CPs, such as NCP, ECP, LCP, ELCP, etc. Within the same time-domain symbol under the same SCS condition, NCP... <ECP<LCP<ECP。

[0333] In some embodiments, the type of the CP, or the method for calculating the length of the CP, includes at least one of the following:

[0334] Method 1:

[0335] Based on the length of the time-domain resource and the number of mapped time-domain symbols, the effective length of the time-domain symbols is fixed, and the CP length of the time-domain symbols is scaled proportionally. Assuming the length of the time-domain resource is L, the number of mapped time-domain symbols is M, and the effective length of the time-domain symbols is G, then the CP length is (LM*G) / M.

[0336] Method 2:

[0337] The percentage of the CP (Content Component) in the effective length of the time-domain symbols is determined based on the length of the time-domain resources and the number of mapped time-domain symbols. The CP length of the time-domain symbols is scaled proportionally. Assuming the length of the time-domain resources is L, the number of mapped time-domain symbols is M, and the percentage of the CP in the effective length of the time-domain symbols is G, then the CP length is (L*G) / (M+M*G).

[0338] Method 3:

[0339] The CP (Content Component) length is determined by the percentage of the time-domain symbol length based on the time-domain resource length and the number of mapped time-domain symbols. The CP length is then scaled proportionally to the time-domain symbol length. For example, if the time-domain resource length is L, the number of mapped time-domain symbols is M, and the CP length is G, then the CP length is (L*G) / M.

[0340] In some embodiments, communication and / or sensing services are transmitted on a first time-domain resource configured by a network device. The first time-domain resource includes at least one time-domain symbol, which can be continuous or non-continuous. The time-domain symbol contains different types of CPs, such as NCP, ECP, LCP, ELCP, etc. Within the same time-domain symbol under the same SCS condition, NCP... <ECP<LCP<ECP。

[0341] In some embodiments, the effective length of the time-domain symbol is calculated in at least one of the following ways:

[0342] Method 1:

[0343] Based on the length of the time-domain resource and the number of mapped time-domain symbols, the CP length is fixed, and the effective length of the time-domain symbols is scaled proportionally. Assuming the length of the time-domain resource is L, the number of mapped time-domain symbols is M, and the CP length is G, then the effective length of the time-domain symbol is (LM*G) / M.

[0344] Method 2:

[0345] The percentage of the effective length of the time-domain symbols occupied by the CP is determined based on the length of the time-domain resources and the number of mapped time-domain symbols, and the effective length of the time-domain symbols is scaled proportionally. Assuming the length of the time-domain resources is L, the number of mapped time-domain symbols is M, and the percentage of the effective length of the time-domain symbols occupied by the CP is G, then the effective length of the time-domain symbols is L / (M+M*G).

[0346] Method 3:

[0347] The effective length of the time-domain symbol is determined by the percentage of the time-domain symbol length occupied by the CP (Content Processing) based on the length of the time-domain resource and the number of mapped time-domain symbols, and scaled proportionally. Assuming the time-domain resource length is L, the number of mapped time-domain symbols is M, and the percentage of the time-domain symbol length occupied by the CP is G, then the effective length of the time-domain symbol is (LL*G) / M.

[0348] In some embodiments, communication and / or sensing services are transmitted on a first time-domain resource, which is configured by a network device. The first time-domain resource includes at least one time-domain symbol, which may be consecutive time-domain symbols. Further, the method for determining the number of time-domain symbols in the first time-domain resource includes at least one of the following:

[0349] Method 1:

[0350] For a first time unit (a first time domain resource may include one or more first time units), the protocol predefines a candidate set of time domain symbols, where the number M in the candidate set is a positive integer. The first time unit can be 1, 0.5, or 0.25 time slots / radio subframes, etc. For example, the candidate set of time domain symbols for one time slot might be 16, 14, 12, 8, or 6. The number of these candidate symbols is configured / indicated to the terminal device by the network device via fifth signaling. This fifth signaling includes DCI, RRC, MAC CE, etc.

[0351] Figure 6 is a schematic diagram of a first time-domain resource according to an example.

[0352] In one implementation, the first time unit is a time slot. Resource allocation is done at the time slot level, with the indicated time slot containing either 4 or 6 time-domain symbols. The time-domain symbol distribution is shown in Figure 6 when 4 or 6 time-domain symbols are indicated. The length of each time-domain symbol is the first time unit divided by the number of time-domain symbols.

[0353] Method 2:

[0354] For the first time unit, the protocol predefines a candidate set of time-domain symbols, where the number M in the candidate set is a positive integer. The first time unit can be 1, 0.5, or 0.25 time slots / radio subframes, etc. For example, the candidate set C for the number of time-domain symbols in one time slot is 16, 14, 12, 8, or 6. The number of candidates is determined by predefined rules in the protocol. The candidate set for sensing services is A, and the candidate set for communication services is B. A belongs to C, and B belongs to C.

[0355] In some embodiments, communication and / or sensing services are transmitted on a first time-domain resource configured by a network device. The first time-domain resource includes at least one time-domain symbol, which may be consecutive time-domain symbols. The determination of the extended CP can be based on at least one of the following methods:

[0356] Method 1:

[0357] Assume that the CP length of a typical Orthogonal Frequency Division Multiplexing (OFDM) symbol is the normal CP, i.e., NCP. A longer CP, i.e., LCP, is added to the OFDM symbol of the first signal. When the last time-domain symbol of the first signal is carried by the nth symbol, the CP of the (n+1)th time-domain symbol is the extended CP. The first signal includes at least one of sensing RS and broadcast signals. The extended CP can be achieved by adding a CP extension before the base CP, and the length of the extended CP can be equal to the LCP, i.e., NCP + CP extension = LCP. Alternatively, the extended CP can be achieved by directly replacing the base CP with a longer CP (e.g., replacing NCP with LCP). Due to the use of extended CP or LCP, when the next OFDM symbol of the first signal is used for communication, even if there is a large delay and strong multipath classification of the first signal, it will not affect the communication. In this method, the effective length of the OFDM symbol transmitting the first channel is reduced due to the addition of extended CP or LCP to the next OFDM symbol.

[0358] In one implementation, a long CP is added to time-domain symbol n+1 and the sensing RS is transmitted. To protect subsequent transmissions, a CP extension is added before the NCP in symbol n+2. See Figure 2P for details.

[0359] In one implementation, a long CP is added to time-domain symbol n+1 and the sensing RS is transmitted. To protect subsequent transmissions, symbol n+2 replaces the NCP with the LCP. See Figure 2Q for details.

[0360] Method 2:

[0361] When the last time-domain symbol of the first signal is carried by the h-th symbol, the CP of the (h+1)-th time-domain symbol is configured by the network device to be an extended CP. The first signal includes at least one of sensing RS and broadcast signals. The extended CP can be a CP extension added before the base CP, and the length of the extended CP can be equal to the LCP, i.e., NCP + CP_extension = LCP. Alternatively, the extended CP can be the base CP replaced with a longer CP (e.g., NCP replaced with LCP). The network configuration is configured through the sixth signaling, which includes at least one of DCI, MAC CE, and RRC signaling.

[0362] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0363] This disclosure also provides 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 terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0364] 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). 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). Taking a field-programmable gate array (FPGA) as an example, it 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.

[0365] 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. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
