The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0372] In some embodiments, the core network equipment may be a single device, including a first network element, a second network element, etc., or it may be multiple devices or a group of devices, each including all or part of the first network element, the second network element, etc. Network elements may be virtual or physical.

[0373] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0376] In a wireless communication system, signal transmission can occur between network devices and terminal devices. This signal transmission can be either an uplink signal from the terminal device to the network device or a downlink signal from the network device to the terminal device.

[0377] The time-frequency domain resources used for signal transmission between network devices and terminal devices can be configured or indicated by the network devices. For time-domain resources, these resources consist of orthogonal frequency division multiplexing (OFDM) symbols (hereinafter referred to as symbols). In some embodiments, a time slot may include 14 symbols, each with a corresponding symbol format (also called symbol category), which can be configured or indicated by the network devices. In some embodiments, the symbol format can be one of the following: uplink symbols, downlink symbols, or flexible symbols. Uplink symbols are used for uplink transmission, downlink symbols are used for downlink transmission, and flexible symbols are symbols that can be used for either uplink or downlink transmission according to control signaling instructions.

[0378] In some embodiments, signal transmission between network devices and terminal devices may encounter conflicts in signal transmission direction and symbol format, i.e., a mismatch between signal transmission direction and symbol format. For example, a terminal device may be configured to send uplink signals to a network device on six symbols, from symbols 3 to 8, while downlink symbols exist among these six symbols. In this case, a conflict arises between the signal transmission direction and symbol format.

[0379] When signal transmission direction and symbol format conflicts occur between network devices and terminal devices, conflict handling rules can be used to determine whether to continue signal transmission. The signal conflict handling rules for different situations are described below.

[0380] In this embodiment of the disclosure, signal transmission and reception can be performed by the terminal device through higher-level configuration (i.e., RRC message configuration), or by instructing the terminal device to perform signal transmission and reception via DCI. In the following embodiments, the abbreviations used in the process of signal transmission and reception by the terminal device have the following meanings:

[0381] RRC-D: Indicates that the network device configures the terminal device to receive downlink signals via RRC messages;

[0382] RRC-U: Indicates that the network device configures the terminal device to send uplink signals via RRC messages;

[0383] Dynamic-D: Indicates that the network device instructs the terminal device to receive downlink signals via DCI;

[0384] Dynamic-U: Indicates that the network device instructs the terminal device to send uplink signals via DCI;

[0385] any-D: includes RRC-D and / or Dynamic-D;

[0386] any-U: includes RRC-U and / or Dynamic-U.

[0387] In this embodiment of the disclosure, the symbol format of each symbol can be configured via RRC messages, or the symbol format of each symbol can be dynamically indicated via DCI. The RRC message configuring the symbol format and the RRC message configuring the terminal device for signal transmission and reception are different RRC messages; the DCI indicating the symbol format and the DCI indicating the terminal device for signal transmission and reception are different DCIs. In the following embodiments, the abbreviations used for configuring the symbol format of each symbol via RRC messages have the following meanings:

[0388] Semi-D: Indicates a semi-static configuration as a downlink symbol;

[0389] Semi-U: Indicates a semi-static configuration as an uplink symbol;

[0390] Semi-F: Indicates that the semi-static configuration is either flexible symbolic or without semi-static configuration.

[0391] For any symbol, one approach is to configure the symbol format as Semi-D or Semi-U using the tdd-UL-DL-ConfigurationCommon (a cell-level configuration used to provide a common uplink / downlink time slot configuration for all terminal devices within the cell) in the RRC message. Another approach is to configure the symbol format as Semi-D or Semi-U using the tdd-UL-DL-ConfigurationDedicated (a terminal device-level configuration used to provide a customized uplink / downlink time slot configuration for a specific terminal device) in the RRC message.

[0392] For any symbol, one approach is to configure the symbol format as Semi-F using the tdd-UL-DL-ConfigurationCommon in the RRC message; another approach is to configure the symbol format as Semi-F using the tdd-UL-DL-ConfigurationDedicated in the RRC message; and a third approach is to not configure the symbol using either tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, in which case the symbol defaults to Semi-F.

[0393] Regarding the symbol format indicated by the DCI, specifically the symbol format of each symbol indicated by the slot format indicator (SFI) field included in the DCI, the meanings of the abbreviations are as follows:

[0394] SFI-D: Indicates a downlink symbol indicated by DCI 2-0;

[0395] SFI-U: Indicates an uplink symbol indicated by DCI 2-0;

[0396] SFI-F: Indicates a flexible symbol indicated by DCI 2-0.

[0397] Based on the examples of the abbreviation meanings above, we will first introduce the signal collision handling criteria when transmitting downlink signals between network devices and terminal devices, referring to Table 1. In the example in Table 1, the network device is configured with Dynamic Signaling (DCI 2-0) to indicate the symbol format of each symbol, and the terminal device successfully receives DCI 2-0. The relevant downlink signals may include, for example, the Physical Downlink Shared Channel (PDSCH), Channel State Information Reference Signal (CSI-RS), Positioning Reference Signal (PRS), Physical Downlink Control Channel (PDCCH), Type 0-PDCCH Common Search Space set (Type 0-PDCCH CSS set), etc.

[0398] Table 1

[0399] In the example in Table 1, signaling A is used to instruct the terminal device to receive downlink signals in the first symbol set. Signaling A can be, for example, an RRC message or a DCI. Signaling B is used to indicate the symbol category. In the example in Table 1, signaling B is DCI 2-0, used to indicate the DCI of the symbol format.

[0400] For item 2-1-1, the higher-layer configured terminal equipment receives downlink signals (i.e., RRC configuration signal reception) in the first symbol set, wherein the downlink signals are PDSCH or CSI-RS; DCI 2-0 indicates that all symbols in the first symbol set are downlink symbols (i.e., SFI-D). In this case, the terminal equipment receives PDSCH or CSI-RS in the first symbol set.

[0401] Regarding item 2-1-2, the higher-layer configured terminal equipment receives downlink signals (i.e., RRC configuration signal reception) in the first symbol set, where the downlink signal is PDSCH or CSI-RS; DCI 2-0 indicates that at least one symbol in the first symbol set is an uplink symbol (i.e., SFI-U) or a flexible symbol (i.e., SFI-F). In this case, because the transmission direction of the downlink signal conflicts with the symbol format, the terminal equipment cancels the reception of PDSCH or CSI-RS in the first symbol set.

[0402] Regarding item 2-2-1, the higher-layer configured terminal equipment receives downlink signals (i.e., RRC configuration signal reception) in the first symbol set, where the downlink signal is PRS; DCI 2-0 indicates that the symbols in the first symbol set are downlink symbols (i.e., SFI-D) or flexible symbols (i.e., SFI-F). When the symbols in the first symbol set are downlink symbols or flexible symbols (i.e., the first symbol set does not include uplink symbols), the terminal equipment receives PRS in the first symbol set.

[0403] Regarding item 2-2-2, the higher-layer configured terminal equipment receives downlink signals (i.e., RRC configuration signal reception) in the first symbol set, where the downlink signal is PRS; DCI 2-0 indicates that at least one symbol in the first symbol set is an uplink symbol (i.e., SFI-U). In this case, because the transmission direction of the downlink signal conflicts with the symbol format, the terminal equipment cancels the reception of PRS in the first symbol set.

[0404] For item 6-1, DCI indicates that the terminal device receives downlink signals in the first symbol set, wherein the downlink signals are PDSCH or CSI-RS; DCI 2-0 indicates that all symbols in the first symbol set are flexible symbols (i.e., SFI-F). In this case, the terminal device receives PDSCH or CSI-RS in the first symbol set.

[0405] Regarding item 6-2, DCI indicates that the terminal device receives downlink signals in the first symbol set, where the downlink signals are PDSCH or CSI-RS; DCI 2-0 indicates that the first symbol set includes uplink symbols (i.e., SFI-U). This is a situation that the terminal device does not expect, that is, the terminal device does not expect DCI-2-0 to indicate the presence of uplink symbols in the first symbol set.

[0406] For item 13-2, the terminal device is configured to receive a Type 0-PDCCH CSS set in the first symbol set; DCI-2-0 indicates that the first symbol set includes an uplink symbol (i.e., SFI-U). This is a situation that the terminal device does not expect, that is, the terminal device does not expect DCI-2-0 to indicate the presence of an uplink symbol in the first symbol set.

[0407] For item 14-1, the terminal device is configured to receive the PDCCH in the first symbol set; DCI 2-0 indicates that all symbols in the first symbol set are downlink symbols (i.e., SFI-D). In this case, the terminal device receives the PDCCH in the first symbol set.

[0408] For item 14-3, the terminal device is configured to receive the PDCCH in the first symbol set; DCI 2-0 indicates that the first symbol set includes uplink symbols or flexible symbols. In this case, the terminal device cancels receiving the PDCCH in the first symbol set.

[0409] The implementation of the example in Table 1 will be introduced below with a specific example.

[0410] Figure 1b is a schematic diagram of collision handling in a downlink signal transmission process according to an embodiment of this disclosure. As shown in Figure 1b, the horizontal axis represents time and the vertical axis represents the frequency domain. In Figure 1b, five time slots are illustrated, namely time slot #0, time slot #1, time slot #2, time slot #3, and time slot #4.

[0411] For time slot #3, it comprises 14 symbols, denoted as OS#0-13. Network devices can configure the symbol format of each symbol via DCI 2-0. For each symbol in time slot #3, OS#0-5 are downlink symbols (i.e., SFI-D), OS#6-8 are flexible symbols (i.e., SFI-F), and OS#9-13 are uplink symbols (i.e., SFI-U). Figure 1b illustrates several possible scenarios from 1) to 8):

[0412] 1) The higher-layer configuration terminal equipment receives downlink signals in OS#1-5 of time slot #3, as shown in Figure 1b. This downlink signal is denoted as RRC-D#1. When RRC-D#1 is PDSCH / CSI-RS / PRS, according to items 2-1-1 and 2-2-1 in Table 1, since OS#1-5 of time slot #3 are all downlink symbols, the terminal equipment receives RRC-D#1 in OS#1-5 of time slot #3.

[0413] 2) The high-level configuration terminal equipment receives downlink signals in OS#1-8 of time slot #3, as shown in Figure 1b. This downlink signal is denoted as RRC-D#2.

[0414] When RRC-D#2 is PDSCH / CSI-RS, according to item 2-1-2 in Table 1, since OS#1-8 of time slot #3 includes flexible symbols (OS#6-8 are flexible symbols), the terminal device cancels the reception of RRC-D#2 in OS#1-8 of time slot #3.

[0415] When RRC-D#2 is PRS, according to item 2-2-1 of Table 1, since OS#1-8 of time slot #3 is a downlink symbol or a flexible symbol (OS#1-5 is a downlink symbol, OS#6-8 is a flexible symbol), the terminal device receives RRC-D#2 in OS#1-8 of time slot #3.

[0416] 3) The higher-layer configuration terminal equipment receives downlink signals in OS#1-10 of time slot #3, as shown in Figure 1b. This downlink signal is denoted as RRC-D#3. When RRC-D#3 is PDSCH / CSI-RS / PRS, according to items 2-1-2 and 2-2-2 in Table 1, since time slot #3 includes uplink symbols (OS#9-10 are uplink symbols), the terminal equipment cancels the reception of RRC-D#3 in OS#1-10 of time slot #3.

[0417] 4) The DCI instructs the terminal device to receive the downlink signal in OS#6-8 of time slot #3, as shown in Figure 1b. This downlink signal is denoted as Dynamic-D#1. According to item 6-1 in Table 1, since OS#6-8 of time slot #3 are all flexible symbols, the terminal device receives Dynamic-D#1 in OS#6-8 of time slot #3.

[0418] 5) The DCI instructs the terminal device to receive downlink signals in OS#1-10 of time slot #3, as shown in Figure 1b. This downlink signal is denoted as Dynamic-D#2. According to item 6-2 in Table 1, OS#9-10 are uplink symbols, and the terminal device does not expect this to happen.

[0419] 6) The terminal device is configured to receive PDCCH in OS#3-5 of time slot #3, as shown in Figure 1b. This downlink signal is denoted as PDCCH#1. According to item 14-1 of Table 1, since OS#3-5 of time slot #3 are all downlink symbols, the terminal device receives PDCCH#1 in OS#3-5 of time slot #3.

[0420] 7) The terminal device is configured to receive PDCCH in OS#7-9 of time slot #3, as shown in Figure 1b. This downlink signal is denoted as PDCCH#2. According to item 14-3 of Table 1, since OS#7-9 of time slot #3 includes uplink symbols (OS#9 is the uplink symbol) and flexible symbols (OS#7-8 is the flexible symbol), the terminal device cancels the reception of PDCCH#2 in OS#7-9 of time slot #3.

[0421] 8) The terminal device is configured to receive downlink signal Type 0-PDCCH CSS set in OS#7-9 of time slot #3. According to item 13-2 of Table 1, the terminal device does not expect this to happen.

[0422] The following section, using Table 2 as an example, describes the signal collision handling guidelines for downlink signal transmission between network devices and terminal devices. For example 2-1-3 / 2-2-3 / 6-3 / 14-2 in Table 2, the network device is configured with Dynamic Signaling (DCI) 2-0 to indicate the symbol format of each symbol, but the terminal device fails to detect DCI 2-0. The relevant downlink signals may include, for example, PDSCH, CSI-RS, PRS, PDCCH, etc.

[0423] Table 2

[0424] In the example in Table 2, signaling A is used to instruct the terminal device to receive downlink signals in the first symbol set. Signaling A can be, for example, an RRC message or a DCI. Signaling B is used to indicate the symbol category. In the example in Table 2, signaling B is DCI 2-0.

[0425] Regarding item 2-1-3, the higher-layer configuration terminal equipment receives downlink signals (i.e., RRC configuration signal reception) in the first symbol set, where the downlink signal is PDSCH or CSI-RS; DCI 2-0 is used to indicate the symbol category, but the terminal equipment does not detect this signaling, and the first symbol set is Semi-F. In this case, the terminal equipment cancels the reception of PDSCH or CSI-RS in the first symbol set.

[0426] Regarding item 2-2-3, the higher-layer configured terminal equipment receives downlink signals (i.e., RRC configuration signal reception) in the first symbol set, where the downlink signal is PRS; DCI 2-0 is used to indicate the symbol category, but the terminal equipment does not detect this signaling, and the first symbol set is Semi-F. In this case, the terminal equipment receives PRS in the first symbol set.

[0427] For item 14-2, the terminal device is configured to receive PDCCH in the first symbol set; DCI 2-0 is used to indicate the symbol category, but the terminal device does not detect this signaling, and the first symbol set is Semi-F. In this case, the terminal device receives PDCCH in the first symbol set.

[0428] For item 6-3, DCI instructs the terminal device to receive downlink signals (i.e., RRC configuration signal reception) in the first symbol set, where the downlink signal is PDSCH or CSI-RS; DCI 2-0 is used to indicate the symbol category, but the terminal device does not detect this signaling, and the first symbol set is Semi-F. In this case, the terminal device receives PDSCH or CSI-RS in the first symbol set.

[0429] Regarding item 3-1, the higher-layer configuration or DCI instructs the terminal device to receive downlink signals (i.e., RRC configuration signal reception) in the first symbol set, wherein the downlink signal is PDCCH, PDSCH, or CSI-RS; and at least one symbol in the first symbol set is Semi-U. In this case, the terminal device cancels the reception of downlink signals in the first symbol set.

[0430] Regarding item 3-1-2, the higher-layer configuration or DCI instructs the terminal device to receive downlink signals (i.e., RRC configuration signal reception) in the first symbol set, where the downlink signal is PRS; and all symbols in the first symbol set are Semi-U. In this case, the terminal device cancels the reception of PRS in the first symbol set.

[0431] The implementation of the example in Table 2 will be introduced below with a specific example.

[0432] Figure 1c is a second schematic diagram of collision handling in a downlink signal transmission process according to an embodiment of this disclosure. As shown in Figure 1c, the horizontal axis represents time, and the vertical axis represents the frequency domain. In Figure 1c, five time slots are illustrated, namely time slot #0, time slot #1, time slot #2, time slot #3, and time slot #4.

[0433] For time slot #3, time slot #3 includes 14 symbols, denoted as OS#0-13. For each symbol in time slot #3, OS#0-5 are downlink symbols (i.e., Semi-D), OS#6-8 are flexible symbols (i.e., Semi-F), and OS#9-13 are uplink symbols (i.e., Semi-U). Figure 1c illustrates the following possible cases from 1) to 2):

[0434] 1) The terminal device receives the downlink signal in OS#6-8 of time slot #3, as shown in Figure 1c. This downlink signal is denoted as DL#1.

[0435] When DL#1 is configured as PDSCH / CSI-RS (i.e., RRC-D(PDSCH / CSI-RS)) by a higher layer, according to item 2-1-3 in Table 2, since OS#6-8 of time slot #3 are all Semi-F, the terminal device cancels the reception of DL#1 in OS#6-8 of time slot #3.

[0436] When DL#1 is a PRS configured by a higher layer (i.e., RRC-D(PRS)), according to item 2-2-3 of Table 2, since OS#6-8 of time slot #3 are all Semi-F, the terminal device receives DL#1 in OS#6-8 of time slot #3.

[0437] When DL#1 is PDCCH, according to item 14-2 of Table 2, since OS#6-8 of time slot #3 are all Semi-F, the terminal device receives DL#1 in OS#6-8 of time slot #3.

[0438] When DL#1 is the DCI-indicated PDSCH / CSI-RS (i.e., Dynamic-D(PDSCH / CSI-RS)), according to item 6-3 of Table 2, since OS#6-8 of time slot #3 are all Semi-F, the terminal device receives DL#1 in OS#6-8 of time slot #3.

[0439] 2) The terminal device receives the downlink signal in OS#7-9 of time slot #3, as shown in Figure 1c. This downlink signal is denoted as DL#2.

[0440] When DL#2 is a higher-layer configuration or DCI-indicated PDCCH / PDSCH / CSI-RS (i.e., Any-D(PDCCH / PDSCH / CSI-RS)), according to item 3-1 of Table 2, since OS#6-9 of time slot #3 includes Semi-U (OS#9 is Semi-U), the terminal device cancels the reception of DL#2 in OS#6-9 of time slot #3.

[0441] When DL#2 is a higher-layer configuration or a PRS indicated by DCI (i.e., Any-D(PRS)), according to item 3-1-2 in Table 2, since OS#6-9 of time slot #3 includes Semi-U (OS#9 is Semi-U), the terminal device cancels the reception of DL#2 in OS#9 of time slot #3, but can still receive DL#2 in OS#6-8.

[0442] The following section, in conjunction with Table 3, outlines the signal collision handling guidelines for uplink signal transmission between network devices and terminal devices. Relevant uplink signals may include, for example, the Physical Uplink Control Channel (PUCCH), the Physical Uplink Shared Channel (PUSCH), the Physical Random Access Channel (PRACH), and the Sounding Reference Signal (SRS), among others.

[0443] Table 3

[0444] In the example in Table 3, signaling A is used to instruct the terminal device to send an uplink signal in the first symbol set. Signaling A can be, for example, an RRC message or a DCI, and the uplink signal can be, for example, PUCCH, PUSCH, PRACH, SRS, etc. Signaling B is used to indicate the symbol category. In the example in Table 3, signaling B is DCI 2-0.

[0445] Regarding item 1-4-3, the higher-layer configuration terminal equipment sends uplink signals (i.e., RRC configuration signal reception) in the first symbol set, wherein the downlink signal is one of the following: PUCCH, PUSCH, PRACH, SRS; DCI 2-0 is used to indicate the symbol category, but the terminal equipment does not detect this signaling, and the first symbol set is Semi-F.

[0446] In this case, if the terminal device is configured with enableConfiguredUL, the terminal device sends an uplink signal in the first symbol set.

[0447] In this scenario, if the terminal device is not configured with `enableConfiguredUL`, the specific execution behavior is determined based on the terminal device's capabilities. Specifically, if the uplink signal is one of PUCCH, PUSCH, or PRACH, and the terminal device does not support partial cancellation capability, if the first time-domain resource and the first symbol set have overlapping symbols, the terminal device does not intend to cancel the uplink signal transmission; otherwise, the terminal device cancels the uplink signal transmission. If the uplink signal is one of PUCCH, PUSCH, or PRACH, and the terminal device supports partial cancellation capability, the terminal device does not intend to cancel the uplink signal transmission on the overlapping symbols of the first time-domain resource and the first symbol set, and the terminal device cancels the uplink signal transmission on the remaining symbols in the first symbol set. If the uplink signal is SRS, the terminal device does not intend to cancel the uplink signal transmission on the overlapping symbols of the first time-domain resource and the first symbol set, and the terminal device cancels the uplink signal transmission on the remaining symbols in the first symbol set.

[0448] For item 7-3, DCI instructs the terminal device to transmit an uplink signal on the first symbol set, wherein the downlink signal is one of the following: PUCCH, PUSCH, PRACH, or SRS; DCI 2-0 is used to indicate the symbol category, but the terminal device does not detect this signaling, and the first symbol set is Semi-F. In this case, the terminal device transmits an uplink signal on the first symbol set.

[0449] With respect to item 4-1, the higher-layer configuration or DCI instructs the terminal device to transmit uplink signals in the first symbol set, wherein the downlink signals are one of the following: PUCCH, PUSCH, PRACH, SRS; and at least one symbol in the first symbol set is Semi-D. In this case, the terminal device cancels the transmission of uplink signals on the first symbol set.

[0450] The implementation of the example in Table 3 will be introduced below with a specific example.

[0451] Figure 1d is a schematic diagram of collision handling in an uplink signal transmission process according to an embodiment of this disclosure. As shown in Figure 1d, the horizontal axis represents time and the vertical axis represents the frequency domain. In Figure 1d, five time slots are illustrated, namely time slot #0, time slot #1, time slot #2, time slot #3, and time slot #4.

[0452] For time slot #3, time slot #3 includes 14 symbols, denoted as OS#0-13. Among them, OS#0-1 in time slot #3 is Semi-D, and OS#2-13 is Semi-F. The first time domain resource includes OS#2-13 of time slot #2 and OS#0-3 of time slot #3. Figure 1d illustrates the following possible cases in 1) to 2):

[0453] 1) The first symbol set includes OS#2-11 of time slot #3. The first symbol set is the time domain resource used by the terminal device to send uplink signals, as shown in Figure 1d. The uplink signal is denoted as UL#1.

[0454] In some embodiments, DCI instructs the terminal device to transmit UL#1 in OS#2-11 of time slot #3, wherein UL#1 is one of the following: PUCCH / PUSCH / PRACH / SRS. As can be seen from item 7-3 of Table 3, the terminal device transmits UL#1 in OS#2-11 of time slot #3.

[0455] In some embodiments, the higher layer configures the terminal device to send UL#1 in OS#2-11 of time slot #3, where UL#1 is one of the following: PUCCH / PUSCH / PRACH / SRS, and the terminal device is configured with enableConfiguredUL. According to item 1-4-3 in Table 3, the terminal device sends UL#1 in OS#2-11 of time slot #3.

[0456] In some embodiments, the higher layer configures the terminal device to send UL#1 in OS#2-11 of time slot #3, and the terminal device does not configure enableConfiguredUL. According to item 1-4-3 of Table 3, if UL#1 is one of the following: PUCCH / PUSCH / PRACH, and the terminal device does not support partial cancellation capability, then the terminal device sends an uplink signal in OS#2-11 of time slot #3; if UL#1 is one of the following: PUCCH / PUSCH / PRACH, and the terminal device supports partial cancellation capability, then the terminal device does not expect to cancel the transmission of UL#1 in OS#2-3 of time slot #3, and the terminal device cancels the transmission of UL#1 in OS#4-11 of time slot #3; if UL#1 is SRS, then the terminal device does not expect to cancel the transmission of UL#1 in OS#2-3 of time slot #3, and the terminal device cancels the transmission of UL#1 in OS#4-11 of time slot #3.

[0457] 2) The first symbol set includes OS#4-13 of time slot #3. The first symbol set is the time domain resource used by the terminal device to send uplink signals, as shown in Figure 1d. The uplink signal is denoted as UL#2.

[0458] In some embodiments, DCI instructs the terminal device to transmit UL#2 in OS#4-13 of time slot #3, wherein UL#2 is one of the following: PUCCH / PUSCH / PRACH / SRS. According to item 7-3 of Table 3, the terminal device transmits UL#1 in OS#2-11 of time slot #3.

[0459] In some embodiments, the higher layer configures the terminal device to transmit UL#2 in OS#4-13 of time slot #3, wherein UL#2 is one of the following: PUCCH / PUSCH / PRACH / SRS, and the terminal device is configured with enableConfiguredUL. According to item 1-4-3 in Table 3, the terminal device transmits UL#2 in OS#4-13 of time slot #3.

[0460] In some embodiments, the higher layer configures the terminal device to send UL#2 in OS#4-13 of time slot #3, and the terminal device does not configure enableConfiguredUL. According to item 1-4-3 of Table 3, if UL#2 is one of the following: PUCCH / PUSCH / PRACH, and the terminal device does not support partial cancellation capability, then the terminal device cancels the transmission of uplink signals in OS#4-13 of time slot #3; if UL#2 is one of the following: PUCCH / PUSCH / PRACH, and the terminal device supports partial cancellation capability, then the terminal device cancels the transmission of uplink signals in OS#4-13 of time slot #3; if UL#2 is SRS, then the terminal device cancels the transmission of UL#2 in OS#4-13 of time slot #3.

[0461] 3) The first symbol set includes OS#0-7 of time slot #3. The first symbol set is the time domain resource used by the terminal device to send uplink signals, as shown in Figure 1d. The uplink signal is denoted as UL#3.

[0462] Since OS#0-7 of time slot #3 includes Semi-D (where OS#0-1 of time slot #3 is Semi-D), according to item 4-1 of Table 3, the terminal device cancels the transmission of UL#3 in OS#0-7 of time slot #3.

[0463] In some embodiments, if the terminal device is configured to continuously transmit uplink signals, the terminal device can determine whether an event has occurred that causes the phase continuity and power consistency of two consecutive uplink signals to be lost, the event including at least one of the following:

[0464] In time division duplex (TDD), the time-domain resources between two consecutive uplink signals include downlink time slots;

[0465] The time-domain resources between two consecutive uplink signals include symbols used by the terminal device to receive downlink signals;

[0466] The time-domain resources between two consecutive uplink signals include symbols used by the terminal device to listen to downlink signals;

[0467] The time-domain resources between two consecutive uplink signals include more than 13 symbols (for a normal cyclic prefix) or more than 11 symbols (for an extended cyclic prefix);

[0468] The time-domain resources between two consecutive uplink signals include 13 or fewer symbols, but include symbols used by the terminal equipment to transmit other uplink signals.

[0469] According to the signal conflict handling guidelines, the terminal device cancels the transmission of one of the uplink signals;

[0470] The TCI states of the two uplink signals are different;

[0471] The two uplink signals have different power parameters;

[0472] There is an uplink timing adjustment between the two uplink signals;

[0473] The two uplink signals have different frequencies.

[0474] In the above embodiments, the signal conflict handling criteria when transmitting communication signals between network devices and terminal devices are introduced with reference to Figures 1b to 1d. With the development of communication technology, ISAC technology has been introduced. ISAC technology aims to integrate sensing capabilities into the communication system, enabling the communication system to provide sensing services and communication services to users.

[0475] In some embodiments, ISAC technology can be applied to drone detection, intelligent transportation, and smart factory lighting scenarios, but is not limited to these. By transmitting and receiving sensing signals, relevant information about surrounding targets or the environment can be perceived. In ISAC technology, the signals transmitted by network devices and terminal devices may include sensing signals in addition to communication signals.

[0476] In some embodiments, the wireless signal transmitter may be at least one of the following: a network device (e.g., a base station), a wireless access point, or a terminal device; in some embodiments, the wireless signal receiver may be at least one of the following: a network device (e.g., a base station), a wireless access point, or a terminal device. In some embodiments, the wireless access point may be, for example, a Wi-Fi access point (AP).

[0477] In some embodiments, the wireless signal transmitter and the wireless signal receiver may be the same device or different devices, thus resulting in a variety of different sensing modes.

[0478] Figure 1e is a schematic diagram of the sensing modes provided in an embodiment of this disclosure. As shown in Figure 1e, taking the wireless signal transmitter as a terminal device or base station and the wireless signal receiver as a terminal device or base station as an example, the following sensing modes can be included:

[0479] Sensing mode 1: Terminal device A sends a sensing signal and receives the sensing signal. For details, please refer to example (1) in Figure 1e.

[0480] Sensing mode 2: Base station A sends a sensing signal and base station A receives the sensing signal. For details, please refer to example (2) in Figure 1e.

[0481] Sensing mode 3: Base station A sends a sensing signal and base station B receives the sensing signal. For details, please refer to example (3) in Figure 1e.

[0485] In some embodiments, for sensing mode 1 and sensing mode 2, the wireless signal transmitter and the wireless signal receiver are the same device; therefore, these two sensing modes belong to mono-static sensing modes. Specifically, sensing mode 1 is UE monostatic, and sensing mode 2 is TRP monostatic.

[0486] In some embodiments, for sensing modes 3, 4, 5, and 6, the wireless signal transmitter and receiver are not the same device; therefore, these sensing modes belong to bi-static or multi-static sensing modes. Specifically, sensing mode 3 is TRP-TRP bistatic, sensing mode 4 is TRP-UE bistatic, sensing mode 5 is UE-TRP bistatic, and sensing mode 6 is UE-UE bistatic.

[0487] Sensing signals and communication signals have different characteristics. For example, the urgency and importance of sensing signals are usually higher than those of communication signals. In single-site sensing mode, terminal devices need to send and receive sensing signals on the same time domain resources. Based on this, embodiments of this disclosure provide a communication method in which a first terminal device receives first indication information sent by a first network device, thereby determining the transmission behavior of a first sensing signal based on the first indication information.

[0499] In some embodiments, the first indication information is carried in at least one of the following signaling: a first RRC message, a first DCI, and a first MAC CE.

[0501] In some embodiments, the first network device sends third indication information to the first terminal device, indicating the symbol categories of M first symbols. For any given first symbol, the symbol category belongs to one of the following: uplink symbol, downlink symbol, or flexible symbol. Correspondingly, the first terminal device receives the third indication information sent by the first network device and determines the symbol categories of the M first symbols based on the third indication information.

[0502] In some embodiments, the third indication information is carried in at least one of the following signaling: a second RRC message, a second DCI, or a second MAC CE.

[0544] For example, if the M first symbols include symbols for the first terminal device to receive the first downlink signal, and the first downlink signal is not a sensing signal, then the first terminal device transmits the first sensing signal on at least one first symbol; or if the M first symbols include symbols for the first terminal device to receive the first downlink signal, and the first downlink signal is a sensing signal, and the device configured to receive the first sensing signal is the first terminal device (i.e., single-site sensing mode), then the first terminal device transmits the first sensing signal on at least one first symbol.

[0550] In some embodiments, the first network device sends a first instruction to the first terminal device, the first instruction being used to instruct the first terminal device to cancel sending the first sensing signal. Correspondingly, the first terminal device receives the first instruction sent by the first network device, but does not execute the first instruction. That is, if at least one of conditions 1.1 to 1.3 is met, the first terminal device will still execute the operation of sending the first sensing signal even if it receives the first instruction.

[0590] In some embodiments, if the M first symbols include symbols for the first terminal device to receive the first downlink signal, the first terminal device may also determine whether to cancel sending the first sensing signal based on the signal type of the first downlink signal.

[0591] For example, if the M first symbols include symbols for the first terminal device to receive the first downlink signal, and the first downlink signal is a sensing signal, then the first terminal device cancels the transmission of the first sensing signal; if the M first symbols include symbols for the first terminal device to receive the first downlink signal, and the first downlink signal is a sensing signal, and the device configured to receive the first sensing signal is not the first terminal device (i.e., not in single-site sensing mode), then the first terminal device cancels the transmission of the first sensing signal.

[0592] Regarding condition 2.3 above, if the M first symbols include symbols used by the first terminal device to send the first uplink signal, the first terminal device cancels the transmission of the first sensing signal.

[0593] In some embodiments, the first network device sends a first instruction to the first terminal device, the first instruction being used to instruct the first terminal device to cancel sending the first sensing signal. Correspondingly, the first terminal device receives the first instruction sent by the first network device, but does not execute the first instruction. That is, if at least one of conditions 2.1 to 2.3 is met, the first terminal device will execute the operation of canceling the sending of the first sensing signal regardless of whether it receives the first instruction.

[0594] In step S2205, the first network device determines that the M first symbols satisfy at least one of the following conditions: the M first symbols include downlink symbols and / or flexible symbols; the M first symbols include symbols used by the first terminal device to receive a first downlink signal; and the M first symbols include symbols used by the first terminal device to transmit a first uplink signal.

[0595] The first network device instructs the first terminal device to send a first sensing signal through M first symbols by means of first indication information, and instructs the symbol category of the M first symbols by means of third indication information. Therefore, the first network device can determine whether the M first symbols satisfy at least one of the above conditions 2.1 to 2.3.

[0596] The implementation method by which the first network device determines the M first symbols to satisfy at least one of the conditions 2.1 to 2.3 can be found in the relevant description of step S2203 in Figure 2b, which will not be repeated here.

[0597] In step S2206, the first network device determines that the first terminal device has cancelled sending the first sensing signal.

[0598] If the first network device determines that M first symbols satisfy at least one of conditions 2.1 to 2.3, the first network device can determine that the processing performed by the first terminal device on the first sensing signal through at least one first symbol is to cancel the transmission of the first sensing signal. The implementation method of the first terminal device canceling the transmission of the first sensing signal can be found in the relevant description of step S2204 in Figure 2b, and will not be repeated here.

[0599] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2206. For example, steps S2201 + S2203 + S2204 may be implemented as independent embodiments, and steps S2201 + S2203 + S2204 + S2205 + S2206 may be implemented as independent embodiments, but are not limited thereto.

[0600] In some embodiments, steps S2202, S2205, and S2206 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0601] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0612] Referring to Figure 2c, which is an exemplary interactive schematic diagram of the communication method provided in this embodiment of the present disclosure, the communication method includes the following steps:

[0613] In step S2301, the first network device sends first indication information to the first terminal device. The first indication information is used to indicate that a first sensing signal is sent through M first symbols and to indicate that a second sensing signal is sent through N second symbols.

[0614] In some embodiments, the first network device may be, for example, a serving base station of the first terminal device. The first network device sends first indication information to the first terminal device, and correspondingly, the first terminal device receives the first indication information sent by the first network device.

[0615] In some embodiments, the first indication information is used to instruct the first terminal device to send a first sensing signal through M first symbols, that is, the first indication information is used to instruct the first terminal device to use time-domain resources to send the first sensing signal, where M is a positive integer.

[0616] In some embodiments, the first indication information is used to instruct the first terminal device to send a second sensing signal through N second symbols, that is, the first indication information is used to instruct the first terminal device to use time-domain resources to send the second sensing signal, where N is a positive integer.

[0617] In some embodiments, the device configured to receive the first sensing signal and the device configured to receive the second sensing signal are the same device, which may be, for example, one of the following: a first terminal device, a second terminal device, a first network device, or a second network device.

[0618] In some embodiments, the first indication information is carried in at least one of the following signaling: a first RRC message, a first DCI, or a first MAC CE.

[0619] In step S2302, the first terminal device processes the first sensing signal using at least one of the M first symbols. This processing involves sending the first sensing signal or canceling the sending of the first sensing signal using at least one first symbol.

[0620] The M first symbols are symbols indicated by the first network device for the first terminal device to transmit a first sensing signal. In some embodiments, the first terminal device transmits the first sensing signal on at least one first symbol if the M first symbols satisfy at least one of the following conditions: the M first symbols include uplink symbols and / or flexible symbols; the M first symbols include symbols for the first terminal device to receive a first downlink signal; the M first symbols include symbols for the first terminal device to transmit a first uplink signal.

[0621] In some embodiments, optional implementations of step S2302 can be found in optional implementations of steps S2103 and S2104 in FIG2a, as well as other related parts in the embodiments involved in FIG2a, which will not be repeated here.

[0622] In some embodiments, the first terminal device cancels the transmission of the first sensing signal if the M first symbols satisfy at least one of the following conditions: the M first symbols include downlink symbols and / or flexible symbols; the M first symbols include symbols for the first terminal device to receive the first downlink signal; the M first symbols include symbols for the first terminal device to transmit the first uplink signal.

[0623] In some embodiments, optional implementations of step S2302 can be found in optional implementations of steps S2203 and S2204 in FIG2b, as well as other related parts in the embodiments involved in FIG2b, which will not be repeated here.

[0624] In step S2303, the first terminal device processes the second sensing signal using at least one of the N second symbols. This processing involves sending the second sensing signal or canceling the sending of the second sensing signal using at least one second symbol. The second sensing signal is the sensing signal adjacent to the first sensing signal among the sensing signals sent by the first terminal device configured by the first network device.

[0625] The N second symbols are symbols indicated by the first network device for the first terminal device to transmit a second sensing signal. In some embodiments, the first terminal device transmits a second sensing signal on at least one second symbol if the N second symbols satisfy at least one of the following conditions: the N second symbols include uplink symbols and / or flexible symbols; the N second symbols include symbols for the first terminal device to receive a first downlink signal; the N second symbols include symbols for the first terminal device to transmit a first uplink signal.

[0626] In some embodiments, the process of the first terminal device sending a second sensing signal through at least one second symbol is similar to the process of the first terminal device sending a first sensing signal through at least one first symbol. For details, please refer to the optional implementations of steps S2103 and S2104 in FIG2a, as well as other related parts in the embodiments involved in FIG2a, which will not be repeated here.

[0627] In some embodiments, the first terminal device cancels the transmission of the second sensing signal if the N second symbols satisfy at least one of the following conditions: the N second symbols include downlink symbols and / or flexible symbols; the N second symbols include symbols for the first terminal device to receive the first downlink signal; the N second symbols include symbols for the first terminal device to transmit the first uplink signal.

[0628] In some embodiments, the process of the first terminal device canceling the transmission of the second sensing signal is similar to the process of the first terminal device canceling the transmission of the first sensing signal. For details, please refer to the optional implementation of steps S2203 and S2204 in FIG2b, as well as other related parts in the embodiments involved in FIG2b, which will not be repeated here.

[0629] In step S2304, the first terminal device determines whether a first event has occurred. The first event is an event in which the phase of the first sensing signal and the phase of the second sensing signal are interrupted.

[0630] In some embodiments, the first event is an event that causes an interruption in the phase of the first sensing signal and the second sensing signal during the process of the first terminal device transmitting the first sensing signal and transmitting the second sensing signal.

[0631] In some embodiments, it should be noted that the first sensing signal and the second sensing signal are two adjacent sensing signals that the first network device needs to send when configuring the first terminal device. Regarding the first sensing signal, the first terminal device may send the first sensing signal or cancel sending it; similarly, regarding the second sensing signal, the first terminal device may send the second sensing signal or cancel sending it. That is, the first sensing signal is not necessarily ultimately sent by the first terminal device, and the second sensing signal is not necessarily ultimately sent by the first terminal device.

[0632] In some embodiments, for two consecutive sensing signals (i.e., a first sensing signal and a second sensing signal) sent by a first terminal device configured in the first network device, the first event includes at least one of the following 3.1 to 3.7:

[0633] 3.1 The first time-domain resources between M first symbols and N second symbols satisfy the first condition.

[0634] Among them, M first symbols are symbols indicated by the first network device for the first terminal device to send a first sensing signal, and N second symbols are symbols indicated by the first network device for the first terminal device to send a second sensing signal.

[0635] The first time-domain resource is the time-domain resource between M first symbols and N second symbols. The first time-domain resource may include one or more symbols, or one or more time slots.

[0636] For example, if M first symbols are OS#5-13 of time slot #0 and N second symbols are OS#0-5 of time slot #2, then the time-domain resources between the M first symbols and the N second symbols include time slot #1; if M first symbols are OS#0-5 of time slot #0 and N second symbols are OS#10-13 of time slot #0, then the time-domain resources between the M first symbols and the N second symbols include OS#6-9 of time slot #0.

[0637] In some embodiments, the first condition includes at least one of the following 3.1a to 3.1e:

[0638] 3.1a. The first time domain resources include downlink time slots.

[0639] In some embodiments, the first network device may configure a first time-domain resource as a downlink time slot. For example, the first time-domain resource is time slot #1, and the first network device configures time slot #1 as a downlink time slot using tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. The downlink time slot is used for downlink signal transmission by the first terminal device. When the first time-domain resource includes a downlink time slot, the first time-domain resource satisfies a first condition.

[0640] 3.1b. The first time domain resources include symbols used by the first terminal device to receive downlink signals.

[0641] In some embodiments, if a first network device configures a first terminal device to receive downlink signals on a certain time domain resource, and the time domain resource overlaps with a first delay resource, then the first time domain resource satisfies a first condition. For example, if the first time domain resource includes OS#6-9 of time slot #0, and the first network device configures the first terminal device to receive downlink signals on OS#9-13 of time slot #0, then since the first time domain resource includes OS#9 of time slot #0, and OS#9 of time slot #0 is a symbol used by the first terminal device to receive downlink signals, the first time domain resource satisfies the first condition.

[0642] 3.1c. The first time domain resources include symbols used by the first terminal device to listen to downlink signals.

[0643] In some embodiments, if the first network device configures the first terminal device to listen to downlink signals on a certain time domain resource, and the time domain resource overlaps with the first delay resource, then the first time domain resource satisfies the first condition. In some embodiments, the downlink signals listened to by the first terminal device may include, for example, PDCCH, PDSCH, etc.

[0644] For example, if the first time domain resource includes OS#6-9 of time slot #0, and the first network device configures the first terminal device to listen to downlink signals on OS#9-13 of time slot #0, then since the first time domain resource includes OS#9 of time slot #0, and OS#9 of time slot #0 is a symbol used by the first terminal device to listen to downlink signals, the first time domain resource satisfies the first condition.

[0645] 3.1d. The number of symbols included in the first time-domain resource is greater than or equal to the first quantity.

[0646] In some embodiments, the number of symbols included in the first time-domain resource is related to the length of the cyclic prefix, which is a special prefix for symbols in a wireless system. It is usually located at the end or beginning of a symbol and can be used to combat multipath propagation and inter-symbol interference.

[0647] In some embodiments, if the prefix of the symbols included in the first time-domain resource is a normal cyclic prefix, and the length of the normal cyclic prefix is ​​relatively short, allowing more symbols to be transmitted in the same amount of time, then a larger first quantity can be set. In some embodiments, if the prefix of the symbols included in the first time-domain resource is an extended cyclic prefix, and the length of the extended cyclic prefix is ​​relatively long, providing more guard intervals to combat multipath propagation and inter-symbol interference, then a smaller first quantity can be set.

[0648] For example, if the prefix of the symbols included in the first time-domain resource is a normal cyclic prefix, then the first quantity can be, for example, 13. If the number of symbols included in the first time-domain resource is greater than 13, the first time-domain resource satisfies the first condition. If the prefix of the symbols included in the first time-domain resource is an extended cyclic prefix, then the first quantity can be, for example, 11. If the number of symbols included in the first time-domain resource is greater than 11, the first time-domain resource satisfies the first condition.

[0649] 3.1e. The first time domain resources include symbols used by the first terminal device to transmit uplink signals.

[0650] In some embodiments, if a first network device configures a first terminal device to transmit an uplink signal on a certain time domain resource, and the time domain resource overlaps with a first delay resource, then the first time domain resource satisfies a first condition. For example, if the first time domain resource includes OS#6-9 of time slot #0, and the first network device configures the first terminal device to transmit an uplink signal on OS#9-13 of time slot #0, then since the first time domain resource includes OS#9 of time slot #0, and OS#9 of time slot #0 is a symbol used by the first terminal device to transmit an uplink signal, the first time domain resource satisfies the first condition.

[0651] The above embodiments introduce a first condition. When the first time domain resources meet the first condition, the first terminal device can determine that a first event has occurred, namely, an event that causes the phase of the first sensing signal and the second sensing signal to be interrupted during the process of the first terminal device sending the first sensing signal and sending the second sensing signal.

[0652] 3.2 The first terminal device cancels the transmission of the first sensing signal.

[0653] In some embodiments, the first terminal device may transmit a first sensing signal on at least one of the M first symbols, or it may cancel transmitting the first sensing signal. For example, if the first terminal device satisfies at least one of conditions 2.1 to 2.3 above, the first terminal device cancels transmitting the first sensing signal.

[0654] If the first terminal device cancels the transmission of the first sensing signal, the first sensing signal will not have a phase. In this case, the phases of the first sensing signal and the second sensing signal will be interrupted.

[0655] 3.3 The first terminal device cancels the transmission of the second sensing signal.

[0656] In some embodiments, the first terminal device may transmit a second sensing signal on at least one of the N second symbols, or it may cancel transmitting the second sensing signal. For example, the first terminal device cancels transmitting the second sensing signal if the N second symbols satisfy at least one of the following conditions: the N second symbols include downlink symbols and / or flexible symbols; the N second symbols include symbols for the first terminal device to receive a first downlink signal; or the N second symbols include symbols for the first terminal device to transmit a first uplink signal.

[0657] If the first terminal device cancels the transmission of the second sensing signal, the second sensing signal will not have a phase. In this case, the phase of the first sensing signal and the second sensing signal will be interrupted.

[0658] 3.4 The TCI state of the first sensing signal is different from that of the second sensing signal.

[0659] TCI status refers to information related to the quasi-co-location (QCL) of a signal, also known as spatial reception parameters, spatial relationship information, etc. TCI status is used to indicate the configuration of signal / channel reception and transmission processing.

[0660] In this embodiment of the disclosure, the TCI state of the first sensing signal may include parameters such as the QCL type of the first sensing signal, and the TCI state of the second sensing signal may include parameters such as the QCL type of the second sensing signal. If the TCI states of the first sensing signal and the second sensing signal are different, then the QCL relationship of the first sensing signal and the QCL relationship of the second sensing signal are different, which will lead to a discontinuity in the phase of the first sensing signal and the phase of the second sensing signal.

[0661] 3.5 The power parameters of the first sensing signal and the second sensing signal are different.

[0662] The power parameters of the sensed signal may include, for example, the instantaneous power, average power, effective power, peak power, path loss factor, target received power, path loss reference signal, etc. In some cases, if the power parameters of the first sensed signal and the second sensed signal are different, it may lead to a phase discontinuity between the two signals. For example, during the transmission of the first and second sensed signals by the first terminal device, the power parameters may be adjusted according to channel conditions. If the power parameters of the first and second sensed signals are different, it may lead to a phase discontinuity. Similarly, during the signal amplification process of the first and second sensed signals, if the power parameters are different, it may increase nonlinear effects, potentially introducing additional phase distortion, thus causing a phase discontinuity, and so on.

[0663] 3.6 There is an uplink timing adjustment between the first sensing signal and the second sensing signal.

[0664] Uplink timing adjustment is performed during signal transmission to ensure that signals from different transmitters arrive at the receiver accurately and to avoid mutual interference. During uplink timing adjustment, due to factors such as propagation delay and device clock differences, signals from different transmitters may arrive at the receiver with time discrepancies, leading to signal overlap or misalignment. Therefore, uplink timing adjustment is necessary. This process can cause a phase discontinuity between the first and second sensing signals. For example, gain switching may occur during uplink timing adjustment, introducing additional phase changes and resulting in phase discontinuity.

[0665] 3.7 The frequencies of the first sensing signal and the second sensing signal are different.

[0666] The fact that the frequencies of the first sensing signal and the second sensing signal are different indicates that there is a frequency hopping between the first sensing signal and the second sensing signal. In this case, the phases of the first sensing signal and the second sensing signal are discontinuous.

[0667] In some embodiments, for a first terminal device in a reduced-capacity half-duplex configuration, the first event may include at least one of the above-described 3.1a, 3.1b, 3.1c, 3.1e, 3.2, and 3.3. The first terminal device in a reduced-capacity half-duplex configuration may, for example, be a frequency division duplex (FDD) half-duplex first terminal device.

[0668] In some embodiments, considering that phase continuity helps improve sensing performance, some or all of the events in the first event can be specially processed to avoid affecting the phase continuity of the first sensing signal and the second sensing signal.

[0669] For example, regarding item 3.1a of the first event above, if the first time domain resource includes a downlink time slot: the first terminal device will not switch from uplink transmission to receiving downlink signals in the first time domain resource, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0670] For example, with respect to item 3.1b of the first event above, if the first time domain resource includes symbols for the first terminal device to receive downlink signals: the first terminal device cancels the reception of downlink signals to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0671] For example, regarding item 3.1c of the first event above, if the first time domain resource includes symbols for the first terminal device to listen to downlink signals: the first terminal device cancels listening to downlink signals to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0672] For example, regarding item 3.1d in the first event above, if the number of symbols included in the first time domain resource is greater than or equal to the first number: the first terminal device will not send or receive signals in the first time domain resource to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0673] For example, regarding item 3.1e of the first event above, if the first time domain resource includes symbols for the first terminal device to transmit uplink signals: the first terminal device cancels the transmission of uplink signals in the first time domain resource to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0674] For example, regarding item 3.2 of the first event above, if the first terminal device meets the relevant conditions for canceling the transmission of the first sensing signal: when the first sensing signal and the second sensing signal need to maintain phase continuity, the first terminal device does not cancel the transmission of the first sensing signal, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0675] For example, regarding item 3.3 of the first event above, if the first terminal device meets the relevant conditions for canceling the transmission of the second sensing signal: when the first sensing signal and the second sensing signal need to maintain phase continuity, the first terminal device does not cancel the transmission of the second sensing signal, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0676] For example, regarding item 3.4 of the first event above, if the TCI state of the first sensing signal and the TCI state of the second sensing signal are different: the first terminal device cancels the TCI switching to ensure that the TCI states of the first sensing signal and the second sensing signal are the same, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0677] For example, regarding item 3.5 of the first event above, if the power parameters of the first sensing signal and the power parameters of the second sensing signal are different: the first terminal device cancels the power parameter adjustment to ensure that the power parameters of the first sensing signal and the second sensing signal are the same, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0678] For example, regarding item 3.6 of the first event above, if there is an uplink timing adjustment between the first sensing signal and the second sensing signal: the first terminal device cancels the uplink timing adjustment between the first sensing signal and the second sensing signal to ensure that the uplink timing of the first sensing signal and the second sensing signal is the same, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0679] For example, regarding item 3.7 of the first event above, if the frequency of the first sensing signal and the frequency of the second sensing signal are different: the first terminal device cancels frequency hopping to ensure that the frequencies of the first sensing signal and the second sensing signal are the same, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0680] In step S2305, when the first event occurs, the first terminal device transmits a first reference signal on P third symbols and a second reference signal on Q fourth symbols; wherein the time slots where the M first symbols are located are the same as the time slots where the P third symbols are located, and the first reference signal is used to determine the phase of the first sensing signal; the time slots where the N second symbols are located are the same as the time slots where the Q fourth symbols are located, and the second reference signal is used to determine the phase of the second sensing signal.

[0681] In the event of the first event, the first terminal device can determine that the phase of the first sensing signal and the phase of the second sensing signal have been interrupted. Then, the first terminal device can determine the phase of the first sensing signal and the phase of the second sensing signal by sending the first reference signal and the second reference signal.

[0682] In some embodiments, the occurrence of the first event is unpredictable, and the first network device may be configured by default to send the first reference signal on P third symbols and send the second reference signal on Q fourth symbols.

[0683] Specifically, the first terminal device transmits a first reference signal on P third symbols, wherein the P third symbols and M first symbols reside in the same time slot. The device configured to receive the first sensing signal, the device configured to receive the first reference signal, the device configured to receive the second sensing signal, and the device configured to receive the second reference signal are all the same device.

[0684] In some embodiments, the device configured to receive the above signal can be, for example, one of the following: a first terminal device, a second terminal device, a first network device, or a second network device. If the device configured to receive the above signal is a first terminal device, then S2305 corresponds to S2305a; if the device configured to receive the first sensing signal is a second terminal device or a second network device, then S2305 corresponds to S2305c; if the device configured to receive the first sensing signal is a first network device, then S2305 corresponds to S2305b.

[0685] In some embodiments, there are overlapping symbols between the P third symbols and the M third symbols. For example, if the M first symbols are OS#0-8 of time slot #0 and the P third symbols are OS#7-13 of time slot #0, then there are overlapping symbols between the P third symbols and the M third symbols, namely OS#7-8 of time slot #0.

[0686] In some embodiments, there are no overlapping symbols between the P third symbols and the M third symbols. For example, if the M first symbols are OS#0-5 of time slot #0 and the P third symbols are OS#7-13 of time slot #0, then there are no overlapping symbols between the P third symbols and the M third symbols.

[0687] In some embodiments, the subcarrier in which the first reference signal is located overlaps with the subcarrier in which the first sensing signal is located.

[0688] In some embodiments, the subcarrier in which the first reference signal is located and the subcarrier in which the first sensing signal is located do not overlap.

[0689] In some embodiments, the RB where the first reference signal is located and the RB where the first sensing signal is located overlap.

[0690] In some embodiments, the RB where the first reference signal is located and the RB where the first sensing signal is located do not overlap.

[0691] Specifically, the first terminal device transmits a second reference signal on Q fourth symbols, wherein the time slots containing N second symbols are the same as the time slots containing Q fourth symbols.

[0692] In some embodiments, there are overlapping symbols between the Q fourth symbols and the N second symbols. For example, if the N second symbols are OS#0-6 of time slot #1 and the Q fourth symbols are OS#6-13 of time slot #1, then there are overlapping symbols between the Q fourth symbols and the N second symbols, namely OS#6 of time slot #0.

[0693] In some embodiments, there are no overlapping symbols between the Q fourth symbols and the N second symbols. For example, if the N second symbols are OS#0-5 of time slot #0 and the Q fourth symbols are OS#7-13 of time slot #0, then there are no overlapping symbols between the P third symbols and the N second symbols.

[0694] In some embodiments, the subcarrier in which the second reference signal is located overlaps with the subcarrier in which the second sensing signal is located.

[0695] In some embodiments, the subcarrier in which the second reference signal is located and the subcarrier in which the second sensing signal is located do not overlap.

[0696] In some embodiments, the RB where the second reference signal is located overlaps with the RB where the second sensing signal is located.

[0697] In some embodiments, the RB containing the second reference signal and the RB containing the second sensing signal do not overlap.

[0698] In the event of the first event, the first terminal device can determine that the phase of the first sensing signal and the phase of the second sensing signal have been interrupted. Then, the first terminal device can determine the phase of the first sensing signal and the phase of the second sensing signal by sending the first reference signal and the second reference signal.

[0699] In some embodiments, the first reference signal belongs to the PTRS. In some embodiments, the second reference signal belongs to the PTRS. The PTRS can be used to accurately track and correct phase changes of the first sensing signal.

[0700] In step S2306, the first network device determines the processing performed by the first terminal device on the first sensing signal through at least one of the M first symbols, wherein the processing is to send the first sensing signal through at least one first symbol or to cancel sending the first sensing signal.

[0701] The first network device instructs the first terminal device to send a first sensing signal through M first symbols via the first indication information, and instructs the symbol category of the M first symbols via the third indication information. Therefore, the first network device can determine the M first symbols and also know the symbol category of the M first symbols.

[0702] In some embodiments, if the M first symbols satisfy at least one of the following conditions, the first network device may determine that the first terminal device transmits a first sensing signal on at least one first symbol: the M first symbols include uplink symbols and / or flexible symbols; the M first symbols include symbols for the first terminal device to receive a first downlink signal; the M first symbols include symbols for the first terminal device to transmit a first uplink signal.

[0703] In some embodiments, a first network device may determine that a first terminal device has cancelled transmitting a first sensing signal if the M first symbols satisfy at least one of the following conditions: the M first symbols include downlink symbols and / or flexible symbols; the M first symbols include symbols for the first terminal device to receive a first downlink signal; and the M first symbols include symbols for the first terminal device to transmit a first uplink signal.

[0704] In some embodiments, optional implementations of step S2306 can be found in optional implementations of step S2302 in FIG2c, and other related parts in the embodiments involved in FIG2c, which will not be repeated here.

[0705] In step S2307, the first network device determines the processing performed by the first terminal device on the second sensing signal through at least one of the N second symbols, wherein the processing is to send the second sensing signal through at least one second symbol or to cancel sending the second sensing signal.

[0706] In some embodiments, optional implementations of step S2307 can be found in optional implementations of step S2303 in FIG2c, and other related parts in the embodiments involved in FIG2c, which will not be repeated here.

[0707] In step S2308, the first network device determines whether a first event has occurred. The first event is an event in which the phase of the first sensing signal and the phase of the second sensing signal are interrupted.

[0708] In some embodiments, optional implementations of step S2308 can be found in optional implementations of step S2304 in FIG2c, and other related parts in the embodiments involved in FIG2c, which will not be repeated here.

[0709] In step S2309, the first network device determines whether the phase of the first sensing signal and the phase of the second sensing signal are continuous based on whether the first event has occurred.

[0710] Since the first terminal device is the transmitting device for both the first and second sensing signals, if the first event does not occur, the phases of the first and second sensing signals transmitted by the first terminal device are continuous. If the first event occurs, the phases of the first and second sensing signals are discontinuous.

[0711] In step S2310, the first network device sends a fourth indication message to the second terminal device / second network device, where the second terminal device / second network device is a device that receives the first sensing signal and the second sensing signal.

[0712] In some embodiments, the second terminal device is connected to the first network device, and the first network device / sensing function (SF) configures the second terminal to receive the first sensing signal and the second sensing signal. The SF can also be referred to as a sensing network element.

[0713] In some embodiments, the second terminal device is connected to the second network device, and the second network device / SF configures the second terminal to receive the first sensing signal and the second sensing signal.

[0714] In some embodiments, the second network device is configured by SF to receive the first sensing signal and the second sensing signal.

[0715] In some embodiments, step S2310 is an optional step. If the device configured by the first network device to receive the first sensing signal and the second sensing signal is a first terminal device or a first network device, then step S2310 does not need to be executed.

[0716] In some embodiments, if the device receiving the first sensing signal and the second sensing signal is a second terminal device, the first network device sends a fourth indication information to the second terminal device. The fourth indication information is used to indicate whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[0717] In some embodiments, if the first network device is the serving base station of the second terminal device, the first network device can directly send the fourth indication information to the second terminal device. Accordingly, the second terminal device receives the fourth indication information sent by the first network device and can determine whether the phases of the first sensing signal and the second sensing signal are continuous based on the fourth indication information.

[0718] In some embodiments, if the first network device is not the serving base station of the second terminal device, the first network device may send a fourth indication information to the serving base station of the second terminal device, and then the serving base station of the second terminal device may send the fourth indication information to the second terminal device.

[0719] In some embodiments, if the device receiving the first sensing signal and the second sensing signal is a second terminal device, the sensing network element can send a fourth indication information to the second terminal device. The fourth indication information is used to indicate whether the phases of the first sensing signal and the second sensing signal are continuous. For example, the first network device can send the fourth indication information to the sensing network element, and then the sensing network element can send the fourth indication information to the second terminal device.

[0720] In some embodiments, if the device receiving the first sensing signal and the second sensing signal is a second network device, the first network device sends a fourth indication information to the second network device. The fourth indication information is used to indicate whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[0721] In some embodiments, if the device receiving the first sensing signal and the second sensing signal is a second network device, a fourth indication information can be sent from the sensing network element to the second network device. This fourth indication information indicates whether the phases of the first sensing signal and the second sensing signal are continuous. For example, the first network device can send the fourth indication information to the sensing network element, and then the sensing network element can send the fourth indication information to the second network device.

[0722] In some embodiments, the fourth indication information may be in the form of a bitmap. For example, if the first terminal device is configured to transmit 10 sensing signals, any two adjacent sensing signals whose phases are continuous can be represented by "1"; any two adjacent sensing signals whose phases are discontinuous can be represented by "0".

[0723] The communication method involved in the embodiments of this disclosure may include at least one of steps S2301 to S2310. For example, steps S2301+S2302+S2303+S2304 can be implemented as an independent embodiment, and steps S2301+S2302+S2303+S2304+S2305 can be implemented as an independent embodiment, but are not limited thereto.

[0724] In some embodiments, steps S2301, S2305, and S2310 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0725] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0726] Referring to Figure 2d, which is an exemplary interactive schematic diagram of the communication method provided in this embodiment of the present disclosure. As shown in Figure 2d, the communication method includes the following steps:

[0727] In step S2401, the first network device sends a first instruction message to the first terminal device. The first instruction message is used to instruct the first terminal device to receive the first sensing signal through M first symbols.

[0728] In some embodiments, a first network device establishes a connection with a first terminal device. The first network device may be, for example, a serving base station of the first terminal device. The first network device sends first indication information to the first terminal device, and correspondingly, the first terminal device receives the first indication information sent by the first network device.

[0729] In some embodiments, the first indication information is used to instruct the first terminal device to receive the first sensing signal through M first symbols, that is, the first indication information is used to instruct the first terminal device to use time-domain resources to receive the first sensing signal, where M is a positive integer.

[0730] In some embodiments, the device configured to send the first sensing signal can be, for example, one of the following: a first terminal device, a second terminal device, a first network device, or a second network device. If the device configured to send the first sensing signal is a first terminal device, the corresponding sensing mode is UE monostatic, as shown in the example in Figure 1e(1); if the device configured to send the first sensing signal is a second terminal device, the corresponding sensing mode is UE-UE bistatic, as shown in the example in Figure 1e(6); if the device configured to send the first sensing signal is a first network device or a second network device, the corresponding sensing mode is TRP-UE bistatic, as shown in the example in Figure 1e(4).

[0731] In some embodiments, the first indication information may also be used to indicate the frequency domain resources used by the first terminal device to receive the first sensing signal.

[0732] In some embodiments, the first indication information may also be used to indicate the time-domain resources and / or frequency-domain resources used by the first terminal device to transmit other signals, such as sensing signals, communication signals (e.g., including uplink signals and / or downlink signals), etc.

[0733] In some embodiments, the first indication information is carried in at least one of the following signaling: a first RRC message, a first DCI, and a first MAC CE. If the first indication information is carried in the first RRC message, the first network device configures the first terminal device to receive the first sensing signal on M first symbols via the first RRC message; if the first indication information is carried in the first DCI, the first network device instructs the first terminal device to receive the first sensing signal on M first symbols via the first DCI; if the first indication information is carried in the first MAC CE, the first network device instructs the first terminal device to receive the first sensing signal on M first symbols by enabling the first MAC CE.

[0734] In step S2402, the first network device sends third indication information to the first terminal device. The third indication information is used to indicate the symbol category of the M first symbols.

[0735] In some embodiments, the first network device sends third indication information to the first terminal device, indicating the symbol categories of M first symbols. For any given first symbol, the symbol category belongs to one of the following: uplink symbol, downlink symbol, or flexible symbol. Correspondingly, the first terminal device receives the third indication information sent by the first network device and determines the symbol categories of the M first symbols based on the third indication information.

[0736] In some embodiments, the third indication information is carried in at least one of the following signaling: a second RRC message, a second DCI, or a second MAC CE.

[0737] In step S2403, the first terminal device determines that the M first symbols satisfy at least one of the following conditions: the M first symbols include downlink symbols and / or flexible symbols; the M first symbols include symbols used by the first terminal device to transmit a second uplink signal; and the M first symbols include symbols used by the first terminal device to receive a second downlink signal.

[0738] After determining the M first symbols, the first terminal device can determine whether to receive the first sensing signal based on the symbol category of each of the M first symbols and / or other signals transmitted on the M first symbols.

[0739] In some embodiments, if M first symbols satisfy at least one of the following conditions 4.1 to 4.3, the first terminal device determines that it receives a first sensing signal on at least one first symbol:

[0749] In some embodiments, the second uplink signal is an uplink signal sent by the first terminal device to the first network device.

Condition 4.2 means that there is overlap between the M first symbols and the time-domain resources used by the first terminal device to transmit the second uplink signal, that is, at least one of the M first symbols is configured to transmit the second uplink signal.

[0750] Condition 4.3: The M first symbols include symbols used by the first terminal equipment to receive the second downlink signal.

[0751] In some embodiments, the second downlink signal is a downlink signal sent by the first network device to the first terminal device.

[0754] When M first symbols satisfy conditions 4.1 to 4.3 above, the first terminal device receives a first sensing signal on at least one first symbol.

[0755] In some embodiments, at least one first symbol is M first symbols, that is, when the M first symbols satisfy conditions 4.1 to 4.3 above, the first terminal device receives the first sensing signal on the M first symbols.

[0756] In some embodiments, at least one first symbol is a downlink symbol among M first symbols, that is, when the M first symbols satisfy conditions 4.1 to 4.3 above, the first terminal device receives a first sensing signal on the downlink symbol among the M first symbols.

[0757] In some embodiments, at least one first symbol is a downlink symbol and / or a flexible symbol among M first symbols, that is, when the M first symbols satisfy conditions 4.1 to 4.3 above, the first terminal device receives a first sensing signal on the downlink symbol and / or the flexible symbol among the M first symbols.

[0758] If the number of at least one first symbol is less than M, then the first terminal device receives the first sensing signal on a subset of the M first symbols.

[0759] With respect to condition 4.1 above, the first terminal device may receive the first sensing signal on at least one first symbol in the following manner:

[0760] All M first symbols are downlink symbols, and the first terminal device receives the first sensing signal on the M first symbols;

[0761] All M first symbols are flexible symbols, and the first terminal device receives the first sensing signal on the M first symbols;

[0769] The M first symbols include uplink symbols, downlink symbols, and flexible symbols. The first terminal device receives a first sensing signal on the downlink symbol among the M first symbols.

[0770] The M first symbols include uplink symbols, downlink symbols, and flexible symbols. The first terminal device receives a first sensing signal on the flexible symbols among the M first symbols.

[0771] The M first symbols include uplink symbols, downlink symbols, and flexible symbols. The first terminal device receives the first sensing signal on the downlink symbols and flexible symbols among the M first symbols.

[0772] Regarding condition 4.2 above, the first terminal device can receive the first sensing signal on at least one first symbol in the following manner:

[0773] The M first symbols include symbols used by the first terminal device to transmit a second uplink signal, and the first terminal device receives a first sensing signal on the M first symbols;

[0774] The M first symbols include symbols used by the first terminal device to transmit a second uplink signal, and the first terminal device receives a first sensing signal on a downlink symbol among the M first symbols (wherein the M first symbols include downlink symbols);

[0775] The M first symbols include symbols used by the first terminal device to transmit a second uplink signal, and the first terminal device receives a first sensing signal on a flexible symbol among the M first symbols (wherein the M first symbols include a flexible symbol);

[0776] The M first symbols include symbols for the first terminal device to transmit a second uplink signal. The first terminal device receives a first sensing signal on the downlink symbols and flexible symbols among the M first symbols (wherein the M first symbols include downlink symbols and flexible symbols).

[0777] In some embodiments, if the M first symbols include symbols for the first terminal device to transmit a second uplink signal, the first terminal device may also determine whether to transmit a first sensing signal on at least one first symbol in conjunction with the signal type of the second uplink signal.

[0778] For example, if the M first symbols include symbols used by the first terminal device to transmit a second uplink signal, and the second uplink signal is not a sensing signal, then the first terminal device receives a first sensing signal on at least one first symbol; or if the M first symbols include symbols used by the first terminal device to transmit a second uplink signal, and the second uplink signal is a sensing signal, and the device configured to transmit the first sensing signal is the first terminal device (i.e., single-site sensing mode), then the first terminal device receives the first sensing signal on at least one first symbol. Wherein, at least one first symbol is any one of the following: M first symbols; downlink symbols among the M first symbols; downlink symbols and / or flexible symbols among the M first symbols.

[0779] Regarding condition 4.3 above, the first terminal device can receive the first sensing signal on at least one first symbol in the following manner:

[0783] The M first symbols include symbols for a first terminal device to receive a second downlink signal, and the first terminal device receives a first sensing signal on the downlink symbols and flexible symbols among the M first symbols.

[0784] In some embodiments, the first network device sends a first instruction to the first terminal device, the first instruction being used to instruct the first terminal device to cancel receiving the first sensing signal. Correspondingly, the first terminal device receives the first instruction sent by the first network device, but does not execute the first instruction. That is, if at least one of conditions 4.1 to 4.3 is met, even if the first instruction is received, the first terminal device will still perform the operation of receiving the first sensing signal.

[0785] In step S2405, the first network device determines that the M first symbols satisfy at least one of the following conditions: the M first symbols include downlink symbols and / or flexible symbols; the M first symbols include symbols used by the first terminal device to transmit a second uplink signal; and the M first symbols include symbols used by the first terminal device to receive a second downlink signal.

[0786] The first network device instructs the first terminal device to receive the first sensing signal through the M first symbols by means of the first indication information, and instructs the symbol category of the M first symbols by means of the third indication information. Therefore, the first network device can determine whether the M first symbols satisfy at least one of the above conditions 4.1 to 4.3.

[0787] The implementation method by which the first network device determines the M first symbols to satisfy at least one of the conditions 4.1 to 4.3 can be found in the relevant description of step S2403 in Figure 2d, which will not be repeated here.

[0789] If the first network device determines that M first symbols satisfy at least one of conditions 4.1 to 4.3, the first network device can determine that the processing of the first sensing signal by the first terminal device through at least one first symbol is to receive the first sensing signal on at least one first symbol. The implementation method of the first terminal device receiving the first sensing signal on at least one first symbol can be found in the relevant description of step S2404 in Figure 2d, and will not be repeated here.

[0790] The communication method involved in the embodiments of this disclosure may include at least one of steps S2401 to S2406. For example, steps S2401 + S2403 + S2404 may be implemented as independent embodiments, and steps S2401 + S2403 + S2404 + S2405 + S2406 may be implemented as independent embodiments, but are not limited thereto.

[0791] In some embodiments, steps S2402, S2405, and S2406 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0792] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0793] Referring to Figure 2e, which is an exemplary interactive schematic diagram of a communication method provided in this embodiment of the present disclosure. As shown in Figure 2e, the communication method includes the following steps:

[0794] Step S2501: The first network device sends a first instruction information to the first terminal device. The first instruction information is used to instruct the first terminal device to receive the first sensing signal through M first symbols.

[0795] In some embodiments, optional implementations of step S2501 can be found in optional implementations of step S2401 in FIG2d, and other related parts in the embodiments involved in FIG2d, which will not be repeated here.

[0796] In step S2502, the first network device sends third indication information to the first terminal device. The third indication information is used to indicate the symbol category of the M first symbols.

[0797] In some embodiments, optional implementations of step S2502 can be found in optional implementations of step S2402 in FIG2d, and other related parts in the embodiments involved in FIG2d, which will not be repeated here.

[0798] In step S2503, the first terminal device determines that the M first symbols satisfy at least one of the following conditions: the M first symbols include uplink symbols and / or flexible symbols; the M first symbols include symbols used by the first terminal device to transmit a second uplink signal; and the M first symbols include symbols used by the first terminal device to receive a second downlink signal.

[0799] After determining the M first symbols, the first terminal device can determine whether to cancel receiving the first sensing signal based on the symbol category of each of the M first symbols and / or other signals transmitted on the M first symbols.

[0800] In some embodiments, if the M first symbols satisfy at least one of the following conditions 5.1 to 5.3, the first terminal device cancels receiving the first sensing signal:

[0801] Condition 5.1: The M first symbols include uplink symbols and / or flexible symbols.

[0802] In some embodiments, condition 5.1 includes at least the following:

[0803] All M first symbols are upline symbols;

[0804] All M first symbols are flexible symbols;

[0805] The M first symbols include uplink symbols and flexible symbols;

[0806] The M first symbols include uplink and downlink symbols;

[0807] The M first symbols include flexible symbols and downlink symbols;

[0808] The M first symbols include uplink symbols, downlink symbols, and flexible symbols.

[0809] Condition 5.2: The M first symbols include symbols used by the first terminal device to transmit the second uplink signal.

[0810] In some embodiments, the second uplink signal is an uplink signal sent by the first terminal device to the first network device. The first network device may pre-configure time-frequency domain resources for transmitting the second uplink signal and indicate these time-frequency domain resources to the first terminal device. Condition 5.2 means that there is overlap between the M first symbols and the time-domain resources used by the first terminal device to transmit the second uplink signal, that is, at least one of the M first symbols is configured to transmit the second uplink signal.

[0811] Condition 5.3: The M first symbols include symbols used by the first terminal equipment to receive the second downlink signal.

[0812] In some embodiments, the second downlink signal is an uplink signal sent by the first network device to the first terminal device. The first network device may pre-configure time-frequency domain resources for transmitting the second downlink signal and indicate these time-frequency domain resources to the first terminal device. Condition 5.3 means that there is overlap between the M first symbols and the time-domain resources for the first terminal device to receive the second downlink signal, that is, at least one of the M first symbols is configured to receive the second downlink signal.

[0813] Step S2504: The first terminal device cancels receiving the first sensing signal, wherein the device configured by the first network device to send the first sensing signal is one of the following: the first terminal device, the first network device, the second terminal device, and the second network device.

[0814] In some embodiments, the device configured to send the first sensing signal can be, for example, one of the following: a first terminal device, a second terminal device, a first network device, or a second network device. If the device configured to send the first sensing signal is a first terminal device, the corresponding sensing mode is UE monostatic, as shown in the example in Figure 1e(1); if the device configured to send the first sensing signal is a second terminal device, the corresponding sensing mode is UE-UE bistatic, as shown in the example in Figure 1e(6); if the device configured to send the first sensing signal is a first network device or a second network device, the corresponding sensing mode is TRP-UE bistatic, as shown in the example in Figure 1e(4).

[0815] If M first symbols satisfy conditions 5.1 to 5.3 above, the first terminal device cancels receiving the first sensing signal. In some embodiments, the terms "the first terminal device cancels receiving the first sensing signal", "the first terminal device does not expect this to happen", and "an error occurs" can be used interchangeably.

[0816] Regarding condition 5.1 above, the first terminal device can cancel receiving the first sensing signal in the following manner:

[0817] All M first symbols are uplink symbols, and the first terminal device cancels the reception of the first sensing signal;

[0818] All M first symbols are flexible symbols, and the first terminal device cancels the reception of the first sensing signal;

[0819] The M first symbols include uplink symbols and flexible symbols, and the first terminal device cancels the reception of the first sensing signal;

[0820] The M first symbols include downlink symbols and flexible symbols, and the first terminal device cancels the reception of the first sensing signal;

[0821] The M first symbols include uplink symbols and downlink symbols, and the first terminal device cancels the reception of the first sensing signal;

[0822] The M first symbols include uplink symbols, downlink symbols, and flexible symbols, and the first terminal device cancels the reception of the first sensing signal.

[0823] Regarding condition 5.2 above, if the M first symbols include symbols used by the first terminal device to send the second uplink signal, the first terminal device cancels receiving the first sensing signal.

[0824] In some embodiments, if the M first symbols include symbols for the first terminal device to transmit a second uplink signal, the first terminal device may also determine whether to cancel receiving the first sensing signal based on the signal type of the second uplink signal.

[0825] For example, if the M first symbols include symbols for the first terminal device to send a second uplink signal, and the second uplink signal is a sensing signal, then the first terminal device cancels receiving the first sensing signal; if the M first symbols include symbols for the first terminal device to send a second uplink signal, and the first downlink signal is a sensing signal, and the device configured to send the first sensing signal is not the first terminal device (i.e., not in single-site sensing mode), then the first terminal device cancels receiving the first sensing signal.

[0826] Regarding condition 5.3 above, if the M first symbols include symbols used by the first terminal device to receive the second downlink signal, the first terminal device cancels the reception of the first sensing signal.

[0827] In some embodiments, the first network device sends a first instruction to the first terminal device, the first instruction being used to instruct the first terminal device to cancel receiving the first sensing signal. Correspondingly, the first terminal device receives the first instruction sent by the first network device, but does not execute the first instruction. That is, if at least one of conditions 5.1 to 5.3 is met, the first terminal device will execute the operation of canceling the reception of the first sensing signal regardless of whether it receives the first instruction.

[0828] In step S2505, the first network device determines that the M first symbols satisfy at least one of the following conditions: the M first symbols include uplink symbols and / or flexible symbols; the M first symbols include symbols used by the first terminal device to transmit a second uplink signal; and the M first symbols include symbols used by the first terminal device to receive a second downlink signal.

[0829] The first network device instructs the first terminal device to receive the first sensing signal through M first symbols by means of the first indication information, and instructs the symbol category of the M first symbols by means of the third indication information. Therefore, the first network device can determine whether the M first symbols satisfy at least one of the above conditions 5.1 to 5.3.

[0830] The implementation method by which the first network device determines the M first symbols to satisfy at least one of the conditions 5.1 to 5.3 can be found in the relevant description of step S2503 in Figure 2e, which will not be repeated here.

[0831] In step S2506, the first network device determines that the first terminal device has cancelled receiving the first sensing signal.

[0832] If the first network device determines that M first symbols satisfy at least one of conditions 5.1 to 5.3, the first network device can determine that the processing performed by the first terminal device on the first sensing signal through at least one first symbol is to cancel receiving the first sensing signal. The implementation method of the first terminal device canceling the reception of the first sensing signal can be found in the relevant description of step S2504 in Figure 2e, and will not be repeated here.

[0833] The communication method involved in the embodiments of this disclosure may include at least one of steps S2501 to S2506. For example, steps S2501 + S2503 + S2504 may be implemented as independent embodiments, and steps S2501 + S2503 + S2504 + S2505 + S2506 may be implemented as independent embodiments, but are not limited thereto.

[0834] In some embodiments, steps S2502, S2505, and S2506 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0835] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0846] Referring to Figure 2f, which is an exemplary interactive schematic diagram of a communication method provided in this embodiment of the present disclosure, the communication method includes the following steps:

[0847] In step S2601, the first network device sends first indication information to the first terminal device. The first indication information is used to indicate that the first sensing signal is received through M first symbols and to indicate that the second sensing signal is received through N second symbols.

[0848] In some embodiments, the first network device may be, for example, a serving base station of the first terminal device. The first network device sends first indication information to the first terminal device, and correspondingly, the first terminal device receives the first indication information sent by the first network device.

[0849] In some embodiments, the first indication information is used to instruct the first terminal device to receive the first sensing signal through M first symbols, that is, the first indication information is used to instruct the first terminal device to use time-domain resources to receive the first sensing signal, where M is a positive integer.

[0850] In some embodiments, the first indication information is used to instruct the first terminal device to receive the second sensing signal through N second symbols, that is, the first indication information is used to instruct the first terminal device to use time-domain resources to receive the second sensing signal, where N is a positive integer.

[0851] In some embodiments, the device configured to send the first sensing signal and the device configured to receive the second sensing signal are the same device, which may be, for example, one of the following: a first terminal device, a second terminal device, a first network device, or a second network device.

[0852] In some embodiments, the first indication information is carried in at least one of the following signaling: a first RRC message, a first DCI, or a first MAC CE.

[0853] In step S2602, the first terminal device processes the first sensing signal through at least one of the M first symbols, which means receiving the first sensing signal or canceling the reception of the first sensing signal through at least one first symbol.

[0854] The M first symbols are symbols indicated by the first network device for the first terminal device to receive the first sensing signal. In some embodiments, the first terminal device receives the first sensing signal on at least one first symbol if the M first symbols satisfy at least one of the following conditions: the M first symbols include downlink symbols and / or flexible symbols; the M first symbols include symbols for the first terminal device to transmit a second uplink signal; the M first symbols include symbols for the first terminal device to receive a second downlink signal.

[0855] In some embodiments, optional implementations of step S2602 can be found in optional implementations of steps S2403 and S2404 in FIG2d, as well as other related parts in the embodiments involved in FIG2d, which will not be repeated here.

[0856] In some embodiments, the first terminal device cancels receiving the first sensing signal if the M first symbols satisfy at least one of the following conditions: the M first symbols include uplink symbols and / or flexible symbols; the M first symbols include symbols for the first terminal device to transmit a second uplink signal; the M first symbols include symbols for the first terminal device to receive a second downlink signal.

[0857] In some embodiments, optional implementations of step S2602 can be found in optional implementations of steps S2503 and S2504 in FIG2e, as well as other related parts in the embodiments involved in FIG2e, which will not be repeated here.

[0858] In step S2603, the first terminal device processes the second sensing signal through at least one of the N second symbols. This processing involves receiving the second sensing signal or canceling the reception of the second sensing signal through at least one second symbol. The second sensing signal is the sensing signal adjacent to the first sensing signal among the sensing signals received by the first terminal device configured by the first network device.

[0859] The N second symbols are symbols indicated by the first network device for the first terminal device to receive the second sensing signal. In some embodiments, the first terminal device receives the second sensing signal on at least one second symbol if the N second symbols satisfy at least one of the following conditions: the N second symbols include downlink symbols and / or flexible symbols; the N second symbols include symbols for the first terminal device to transmit a second uplink signal; the N second symbols include symbols for the first terminal device to receive a second downlink signal.

[0860] In some embodiments, the process by which the first terminal device receives the second sensing signal through at least one second symbol is similar to the process by which the first terminal device receives the first sensing signal through at least one first symbol. For details, please refer to the optional implementations of steps S2403 and S2404 in FIG2d, as well as other related parts in the embodiments involved in FIG2d, which will not be repeated here.

[0861] In some embodiments, the first terminal device cancels receiving the second sensing signal if the N second symbols satisfy at least one of the following conditions: the N second symbols include uplink symbols and / or flexible symbols; the N second symbols include symbols for the first terminal device to transmit the second uplink signal; the N second symbols include symbols for the first terminal device to receive the second downlink signal.

[0862] In some embodiments, the process of the first terminal device canceling the reception of the second sensing signal is similar to the process of the first terminal device canceling the reception of the first sensing signal. For details, please refer to the optional implementation of steps S2503 and S2504 in FIG2e, and other related parts in the embodiments involved in FIG2e, which will not be repeated here.

[0863] In step S2604, the first terminal device determines whether a first event has occurred. The first event is an event in which the phase of the first sensing signal and the phase of the second sensing signal are interrupted.

[0864] In some embodiments, the first event is an event that causes an interruption in the phase of the first sensing signal and the second sensing signal during the process of the first terminal device receiving the first sensing signal and receiving the second sensing signal.

[0865] In some embodiments, it should be noted that the first sensing signal and the second sensing signal are two adjacent sensing signals that the first network device configures the first terminal device to receive. Regarding the first sensing signal, the first terminal device may receive the first sensing signal or may not receive it. Similarly, regarding the second sensing signal, the first terminal device may receive the second sensing signal or may not receive it. In other words, the first sensing signal is not necessarily ultimately received by the first terminal device, and the second sensing signal is not necessarily ultimately received by the first terminal device.

[0866] In some embodiments, for two consecutive sensing signals (i.e., a first sensing signal and a second sensing signal) received by a first terminal device configured with a first network device, the first event includes at least one of the following 6.1 to 6.7:

[0867] 6.1 The first time-domain resources between M first symbols and N second symbols satisfy the first condition.

[0868] Among them, M first symbols are symbols indicated by the first network device for the first terminal device to receive the first sensing signal, and N second symbols are symbols indicated by the first network device for the first terminal device to receive the second sensing signal.

[0869] The first time-domain resource is the time-domain resource between M first symbols and N second symbols. The first time-domain resource may include one or more symbols, or one or more time slots.

[0870] For example, if M first symbols are OS#5-13 of time slot #0 and N second symbols are OS#0-5 of time slot #2, then the time-domain resources between the M first symbols and the N second symbols include time slot #1; if M first symbols are OS#0-5 of time slot #0 and N second symbols are OS#10-13 of time slot #0, then the time-domain resources between the M first symbols and the N second symbols include OS#6-9 of time slot #0.

[0871] In some embodiments, the first condition includes at least one of the following 6.1a to 6.1e:

[0872] 6.1a. The first time domain resources include uplink time slots.

[0873] In some embodiments, the first network device may configure a first time domain resource as an uplink timeslot. For example, the first time domain resource is timeslot #1, and the first network device configures timeslot #1 as an uplink timeslot using tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. Here, the uplink timeslot is a timeslot used by the first terminal device for uplink signal transmission. When the first time domain resource includes an uplink timeslot, the first time domain resource satisfies a first condition.

[0874] 6.1b. The first time domain resources include symbols used by the first terminal device to transmit uplink signals.

[0875] In some embodiments, if a first network device configures a first terminal device to transmit an uplink signal on a certain time domain resource, and the time domain resource overlaps with a first delay resource, then the first time domain resource satisfies a first condition. For example, if the first time domain resource includes OS#6-9 of time slot #0, and the first network device configures the first terminal device to transmit an uplink signal on OS#9-13 of time slot #0, then since the first time domain resource includes OS#9 of time slot #0, and OS#9 of time slot #0 is a symbol used by the first terminal device to transmit an uplink signal, the first time domain resource satisfies the first condition.

[0876] 6.1c. The first time domain resources include symbols used by the first terminal device to listen for uplink signals.

[0877] In some embodiments, if the first network device configures the first terminal device to listen for uplink signals on a certain time domain resource, and the time domain resource overlaps with a first delay resource, then the first time domain resource satisfies the first condition. In some embodiments, the uplink signal listened to by the first terminal device may include, for example, PUSCH, etc.

[0878] For example, if the first time domain resource includes OS#6-9 of time slot #0, and the first network device configures the first terminal device to listen to uplink signals on OS#9-13 of time slot #0, then since the first time domain resource includes OS#9 of time slot #0, and OS#9 of time slot #0 is a symbol used by the first terminal device to listen to uplink signals, the first time domain resource satisfies the first condition.

[0879] 6.1d. The number of symbols included in the first time domain resource is greater than or equal to the first quantity.

[0880] For details on 6.1d, please refer to the optional implementation of 3.1d in step S2304 of Figure 2c, as well as other related parts in the embodiments involved in Figure 2c, which will not be repeated here.

[0881] 6.1e. The first time domain resources include symbols used by the first terminal device to receive downlink signals.

[0882] In some embodiments, if a first network device configures a first terminal device to receive downlink signals on a certain time domain resource, and the time domain resource overlaps with a first delay resource, then the first time domain resource satisfies a first condition. For example, if the first time domain resource includes OS#6-9 of time slot #0, and the first network device configures the first terminal device to receive downlink signals on OS#9-13 of time slot #0, then since the first time domain resource includes OS#9 of time slot #0, and OS#9 of time slot #0 is a symbol used by the first terminal device to receive downlink signals, the first time domain resource satisfies the first condition.

[0883] The above embodiments introduce a first condition. When the first time domain resources meet the first condition, the first terminal device can determine that a first event has occurred, namely, an event that causes the phase of the first sensing signal and the second sensing signal to be interrupted during the process of the first terminal device receiving the first sensing signal and sending the second sensing signal.

[0884] 6.2 The first terminal device cancels the transmission of the first sensing signal.

[0885] In some embodiments, the first terminal device may receive the first sensing signal on at least one of the M first symbols, or it may cancel receiving the first sensing signal. For example, if the first terminal device satisfies at least one of conditions 5.1 to 5.3 above, the first terminal device cancels receiving the first sensing signal.

[0886] If the first terminal device cancels the transmission of the first sensing signal, the first sensing signal will not have a phase. In this case, the phases of the first sensing signal and the second sensing signal will be interrupted.

[0887] 6.3 The first terminal device cancels the transmission of the second sensing signal.

[0888] In some embodiments, the first terminal device may receive a second sensing signal on at least one of the N second symbols, or it may cancel receiving the second sensing signal. For example, the first terminal device cancels receiving the second sensing signal if the N second symbols satisfy at least one of the following conditions: the N second symbols include uplink symbols and / or flexible symbols; the N second symbols include symbols used by the first terminal device to transmit a second uplink signal; or the N second symbols include symbols used by the first terminal device to receive a second downlink signal.

[0889] If the first terminal device cancels the transmission of the second sensing signal, the second sensing signal will not have a phase. In this case, the phase of the first sensing signal and the second sensing signal will be interrupted.

[0890] 6.4 The TCI state of the first sensing signal is different from that of the second sensing signal.

[0891] For details on 6.4, please refer to the optional implementation of 3.4 in step S2304 of Figure 2c, as well as other related parts in the embodiments involved in Figure 2c, which will not be repeated here.

[0892] 6.5 The power parameters of the first sensing signal and the second sensing signal are different.

[0893] For details on 6.5, please refer to the optional implementation of 3.5 in step S2304 of Figure 2c, as well as other related parts in the embodiments involved in Figure 2c, which will not be repeated here.

[0894] 6.6 There is an uplink timing adjustment between the first sensing signal and the second sensing signal.

[0895] For details on 6.6, please refer to the optional implementation of 3.6 in step S2304 of Figure 2c, as well as other related parts in the embodiments involved in Figure 2c, which will not be repeated here.

[0896] 6.7 The frequencies of the first sensing signal and the second sensing signal are different.

[0897] The fact that the frequencies of the first sensing signal and the second sensing signal are different indicates that there is a frequency hopping between the first sensing signal and the second sensing signal. In this case, the phases of the first sensing signal and the second sensing signal are discontinuous.

[0898] In some embodiments, for a first terminal device in a reduced-capacity half-duplex configuration, the first event may include, for example, at least one of 6.1a, 6.1b, 6.1c, 6.1e, 6.2, and 6.3 described above. The first terminal device in a reduced-capacity half-duplex configuration may, for example, be an FDD half-duplex first terminal device.

[0899] In some embodiments, considering that phase continuity helps improve sensing performance, some or all of the events in the first event can be specially processed to avoid affecting the phase continuity of the first sensing signal and the second sensing signal.

[0900] For example, regarding item 6.1a of the first event above, if the first time domain resource includes an uplink time slot: the first terminal device will not switch from receiving downlink signals to transmitting uplink signals in the first time domain resource, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0901] For example, regarding item 6.1b of the first event above, if the first time domain resource includes symbols for the first terminal device to transmit uplink signals: the first terminal device cancels the transmission of uplink signals to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0902] For example, regarding item 6.1c of the first event above, if the first time domain resource includes symbols for the first terminal device to listen to uplink signals: the first terminal device cancels listening to uplink signals to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0903] For example, regarding item 6.1d in the first event above, if the number of symbols included in the first time domain resource is greater than or equal to the first number: the first terminal device will not send or receive signals in the first time domain resource, ensuring the phase continuity of the first sensing signal and the second sensing signal.

[0904] For example, regarding item 6.1e of the first event above, if the first time domain resource includes symbols for the first terminal device to receive downlink signals: the first terminal device cancels receiving downlink signals in the first time domain resource to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0905] For example, regarding item 6.2 of the first event above, if the first terminal device meets the relevant conditions for canceling the transmission of the first sensing signal: when the first sensing signal and the second sensing signal need to maintain phase continuity, the first terminal device does not cancel the transmission of the first sensing signal, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0906] For example, regarding item 6.3 of the first event above, if the first terminal device cancels the transmission of the second sensing signal: when the first sensing signal and the second sensing signal need to maintain phase continuity, the transmission of the second sensing signal is not canceled, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0907] For example, regarding item 6.4 of the first event above, if the TCI state of the first sensing signal and the TCI state of the second sensing signal are different: the first terminal device cancels the TCI switching to ensure that the TCI states of the first sensing signal and the second sensing signal are the same, and to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0908] For example, regarding item 6.5 of the first event above, if the power parameters of the first sensing signal and the power parameters of the second sensing signal are different: the first terminal device cancels the power parameter adjustment to ensure that the power parameters of the first sensing signal and the second sensing signal are the same, and to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0909] For example, regarding item 6.6 of the first event above, if there is an uplink timing adjustment between the first sensing signal and the second sensing signal: the first terminal device cancels the uplink timing adjustment between the first sensing signal and the second sensing signal to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0910] For example, regarding item 6.7 of the first event above, if the frequency of the first sensing signal and the frequency of the second sensing signal are different: the first terminal device cancels frequency hopping to ensure that the frequencies of the first sensing signal and the second sensing signal are the same, and to ensure the phase continuity of the first sensing signal and the second sensing signal.

[0911] In step S2605, when the first event occurs, the first terminal device receives a first reference signal on P third symbols and a second reference signal on Q fourth symbols; wherein the time slots where the M first symbols are located are the same as the time slots where the P third symbols are located, and the first reference signal is used to determine the phase of the first sensing signal; the time slots where the N second symbols are located are the same as the time slots where the Q fourth symbols are located, and the second reference signal is used to determine the phase of the second sensing signal.

[0912] In some embodiments, the occurrence of the first event is unpredictable, and the first network device may be configured by default to receive the first reference signal on P third symbols and the second reference signal on Q fourth symbols.

[0913] In the event of the first event, the first terminal device can determine that the phase of the first sensing signal and the phase of the second sensing signal have been interrupted. Then, the first terminal device can determine the phase of the first sensing signal and the phase of the second sensing signal by receiving the first reference signal and the second reference signal.

[0914] Specifically, the first terminal device receives a first reference signal on P third symbols, wherein the P third symbols and M first symbols reside in the same time slot. The device configured to transmit the first sensing signal, the device configured to transmit the first reference signal, the device configured to transmit the second sensing signal, and the device configured to transmit the second reference signal are all the same device.

[0915] In some embodiments, the device configured to send the above signal can be, for example, one of the following: a first terminal device, a second terminal device, a first network device, or a second network device. If the device configured to send the above signal is a first terminal device, then S2605 corresponds to S2605a; if the device configured to send the first sensing signal is a second terminal device or a second network device, then S2605 corresponds to S2605c; if the device configured to send the first sensing signal is a first network device, then S2605 corresponds to S2605b.

[0916] In some embodiments, there are overlapping symbols between the P third symbols and the M third symbols. For example, if the M first symbols are OS#0-8 of time slot #0 and the P third symbols are OS#7-13 of time slot #0, then there are overlapping symbols between the P third symbols and the M third symbols, namely OS#7-8 of time slot #0.

[0917] In some embodiments, there are no overlapping symbols between the P third symbols and the M third symbols. For example, if the M first symbols are OS#0-5 of time slot #0 and the P third symbols are OS#7-13 of time slot #0, then there are no overlapping symbols between the P third symbols and the M third symbols.

[0918] In some embodiments, the subcarrier in which the first reference signal is located overlaps with the subcarrier in which the first sensing signal is located.

[0919] In some embodiments, the subcarrier in which the first reference signal is located and the subcarrier in which the first sensing signal is located do not overlap.

[0920] In some embodiments, the RB where the first reference signal is located and the RB where the first sensing signal is located overlap.

[0921] In some embodiments, the RB where the first reference signal is located and the RB where the first sensing signal is located do not overlap.

[0922] Specifically, the first terminal device receives the second reference signal on Q fourth symbols, wherein the time slots where the N second symbols are located are the same as the time slots where the Q fourth symbols are located.

[0923] In some embodiments, there are overlapping symbols between the Q fourth symbols and the N second symbols. For example, if the N second symbols are OS#0-6 of time slot #1 and the Q fourth symbols are OS#6-13 of time slot #1, then there are overlapping symbols between the Q fourth symbols and the N second symbols, namely OS#6 of time slot #0.

[0924] In some embodiments, there are no overlapping symbols between the Q fourth symbols and the N second symbols. For example, if the N second symbols are OS#0-5 of time slot #0 and the Q fourth symbols are OS#7-13 of time slot #0, then there are no overlapping symbols between the P third symbols and the N second symbols.

[0925] In some embodiments, the subcarrier in which the second reference signal is located overlaps with the subcarrier in which the second sensing signal is located.

[0926] In some embodiments, the subcarrier in which the second reference signal is located and the subcarrier in which the second sensing signal is located do not overlap.

[0927] In some embodiments, the RB where the second reference signal is located overlaps with the RB where the second sensing signal is located.

[0928] In some embodiments, the RB containing the second reference signal and the RB containing the second sensing signal do not overlap.

[0929] In the event of the first event, the first terminal device can determine that the phase of the first sensing signal and the phase of the second sensing signal have been interrupted. Then, the first terminal device can determine the phase of the first sensing signal and the phase of the second sensing signal by receiving the first reference signal and the second reference signal.

[0930] In some embodiments, the first reference signal belongs to the PTRS. In some embodiments, the second reference signal belongs to the PTRS. The PTRS can be used to accurately track and correct phase changes of the first sensing signal.

[0931] In step S2606, the first network device determines the processing performed by the first terminal device on the first sensing signal through at least one of the M first symbols, wherein the processing is to receive the first sensing signal or cancel receiving the first sensing signal through at least one first symbol.

[0932] In some embodiments, optional implementations of step S2606 can be found in optional implementations of step S2602 in FIG2f, and other related parts in the embodiments involved in FIG2f, which will not be repeated here.

[0933] In step S2607, the first network device determines the processing performed by the first terminal device on the second sensing signal through at least one of the N second symbols, wherein the processing is to receive the second sensing signal or cancel receiving the second sensing signal through at least one second symbol.

[0934] In some embodiments, optional implementations of step S2607 can be found in optional implementations of step S2603 in FIG2f, and other related parts in the embodiments involved in FIG2f, which will not be repeated here.

[0935] In step S2608, the first network device determines whether a first event has occurred. The first event is an event in which the phase of the first sensing signal and the phase of the second sensing signal are interrupted.

[0936] In some embodiments, optional implementations of step S2608 can be found in optional implementations of step S2604 in FIG2f, and other related parts in the embodiments involved in FIG2f, which will not be repeated here.

[0937] In step S2609, the first network device determines whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[0938] In some embodiments, if the first network device determines that a first event has occurred, the first network device can directly determine that the phase of the first sensing signal and the phase of the second sensing signal are discontinuous.

[0939] In some embodiments, if the first network device determines that the first event has not occurred, the first network device can determine that no event causing phase continuity interruption has occurred during the process of the first terminal device receiving the first sensing signal and the second sensing signal. However, this does not mean that the phase of the first sensing signal and the phase of the second sensing signal are necessarily continuous. There may also be cases where the phase of the first sensing signal and the phase of the second sensing signal are discontinuous due to the sending behavior of the transmitting end.

[0940] If the device configured to send the first sensing signal is a first terminal device or a first network device, the first network device can directly determine whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[0941] If the device configured to send the first sensing signal is a second terminal device, the second terminal device can send second indication information to the first network device, indicating whether the phase of the first sensing signal and the phase of the second sensing signal are continuous. Specifically, if the first network device is the serving base station of the second terminal device, the second terminal device can directly send the second indication information to the first network device; if the first network device is not the serving base station of the second terminal device, the second terminal device can send the second indication information to the serving base station of the second terminal device, and then the serving base station of the second terminal device will send the second indication information to the first network device.

[0942] If the device configured to send the first sensing signal is the second terminal device, then the sensing network element can send the second indication information to the first network device to indicate whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[0943] If the device configured to send the first sensing signal is a second network device, the second network device can send a second indication message to the first network device, indicating whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[0944] If the device configured to send the first sensing signal is the second network device, then the sensing network element can send the second indication information to the first network device to indicate whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[0945] In step S2610, the first network device sends second indication information to the first terminal device. The second indication information is used to indicate whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[0946] After the first network device determines whether the phase of the first sensing signal and the phase of the second sensing signal are continuous, the first network device sends second indication information to the first terminal device. Correspondingly, the first terminal device receives the second indication information sent by the first network device and can determine whether the phase of the first sensing signal and the phase of the second sensing signal are continuous based on the second indication information.

[0947] In some embodiments, the second indication information may be in the form of a bitmap. For example, if the first terminal device is configured to transmit 10 sensing signals, any two adjacent sensing signals whose phases are continuous can be represented by "1"; any two adjacent sensing signals whose phases are discontinuous can be represented by "0".

[0948] Referring to Figure 3, Figure 3 is an exemplary interactive schematic diagram of a communication method provided in this embodiment of the present disclosure. As shown in Figure 3, the communication method includes the following steps:

[0949] In step S3101, the first network device sends first instruction information to the first terminal device. The first instruction information is used to instruct the first terminal device to transmit the first sensing signal through M first symbols.

[0950] In some embodiments, a first network device establishes a connection with a first terminal device. The first network device may be, for example, a serving base station of the first terminal device. The first network device sends first indication information to the first terminal device, and correspondingly, the first terminal device receives the first indication information sent by the first network device.

[0951] The first indication information is used to instruct the first terminal device to transmit the first sensing signal through M first symbols, that is, the first indication information is used to instruct the time-domain resources used by the first terminal device to transmit the first sensing signal, where M is a positive integer. In some embodiments, the first indication information can also be used to instruct the frequency-domain resources used by the first terminal device to transmit the first sensing signal.

[0952] In some embodiments, the first indication information is used to instruct the first terminal device to send a first sensing signal via M first symbols. In some embodiments, the device configured to receive the first sensing signal may be, for example, one of the following: a first terminal device, a second terminal device, a first network device, or a second network device.

[0953] In some embodiments, the first indication information is used to instruct a first terminal device to receive a first sensing signal via M first symbols. In some embodiments, the device configured to transmit the first sensing signal may be, for example, one of the following: a first terminal device, a second terminal device, a first network device, or a second network device.

[0954] In some embodiments, the first indication information is carried in at least one of the following signaling: a first RRC message, a first DCI, or a first MAC CE.

[0955] In step S3102, the first terminal device processes the first sensing signal using at least one of the M first symbols.

[0956] The first terminal device processes the first sensing signal, including one of the following: transmitting the first sensing signal through at least one first symbol; canceling the transmission of the first sensing signal; receiving the first sensing signal through at least one first symbol; and canceling the reception of the first sensing signal.

[0957] In some embodiments, the first indication information is used to instruct the first terminal device to send a first sensing signal through M first symbols, then the first terminal device sends the first sensing signal through at least one first symbol, or cancels the sending of the first sensing signal.

[0958] In some embodiments, the first indication information is used to instruct the first terminal device to receive the first sensing signal through M first symbols, then the first terminal device receives the first sensing signal through at least one first symbol, or cancels receiving the first sensing signal.

[0959] In some embodiments, the first network device sends a first instruction to the first terminal device, the first instruction instructing the first terminal device to cancel the transmission of the first sensing signal. Correspondingly, the first terminal device receives the first instruction sent by the first network device, but does not execute the first instruction.

[0960] In some embodiments, the first terminal device determines whether a first event has occurred. The first event is an event in which the phase of the first sensing signal and the phase of the second sensing signal are interrupted. The second sensing signal is a sensing signal adjacent to the first sensing signal in the sensing signals transmitted by the first terminal device configured by the first network device.

[0961] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0962] Referring to Figure 4a, Figure 4a is an exemplary interactive schematic diagram of a communication method provided in an embodiment of this disclosure. As shown in Figure 4a, the communication method includes the following steps:

[0963] In step S4101, the first network device determines that M first symbols satisfy at least one of the following conditions: the M first symbols include downlink symbols and / or flexible symbols; the M first symbols include symbols used by the first network device to receive a first uplink signal.

[0964] After determining the M first symbols, the first network device can determine whether to send a first sensing signal based on the symbol category of each of the M first symbols and / or other signals transmitted on the M first symbols.

[0981] In some embodiments, at least one first symbol is a downlink symbol and / or a flexible symbol among M first symbols, that is, when the M first symbols satisfy conditions 7.1 to 7.2 above, the first network device transmits a first sensing signal on the downlink symbol and / or the flexible symbol among the M first symbols.

[0982] If the number of at least one first symbol is less than M, then the first network device transmits the first sensing signal on a subset of the M first symbols.

[0995] The M first symbols include uplink symbols, downlink symbols, and flexible symbols. The first network device transmits a first sensing signal on the downlink symbols and flexible symbols among the M first symbols.

[0996] With respect to condition 7.2 above, the first network device may transmit a first sensing signal on at least one first symbol in the following manner:

[0997] The M first symbols include symbols for the first network device to receive the first uplink signal, and the first network device transmits the first sensing signal on the M first symbols;

[1001] In some embodiments, if the M first symbols include symbols for the first network device to receive the first uplink signal, the first network device may also determine whether to send the first sensing signal on at least one first symbol in conjunction with the signal type of the first uplink signal.

[1002] For example, if the M first symbols include symbols for the first network device to receive a first uplink signal, and the first uplink signal is not a sensing signal, then the first network device transmits a first sensing signal on at least one first symbol; or if the M first symbols include symbols for the first network device to receive a first uplink signal, and the first uplink signal is a sensing signal, and the device configured to receive the first sensing signal is the first network device (i.e., single-site sensing mode), then the first network device transmits a first sensing signal on at least one first symbol. Wherein, at least one first symbol is any one of the following: the M first symbols; downlink symbols among the M first symbols; downlink symbols and / or flexible symbols among the M first symbols.

[1003] The communication method involved in the embodiments of this disclosure may include at least one of steps S4101 to S4102. For example, step S4102 may be implemented as a standalone embodiment, but is not limited thereto.

[1004] In some embodiments, step S4101 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[1005] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[1006] Referring to Figure 4b, which is an exemplary flowchart of a communication method provided in this embodiment of the present disclosure. As shown in Figure 4a, the communication method includes the following steps:

[1007] In step S4201, the first network device determines that M first symbols satisfy at least one of the following conditions: the M first symbols include uplink symbols and / or flexible symbols; the M first symbols include symbols used by the first network device to receive the first uplink signal.

[1008] After determining the M first symbols, the first network device can determine whether to cancel sending the first sensing signal based on the symbol category of each of the M first symbols and / or other signals transmitted on the M first symbols.

[1009] In some embodiments, if the M first symbols satisfy at least one of the following conditions 8.1 to 8.2, the first network device cancels the transmission of the first sensing signal:

[1010] Condition 8.1: The M first symbols include uplink symbols and / or flexible symbols.

[1011] In some embodiments, condition 8.1 includes at least the following:

[1012] All M first symbols are upline symbols;

[1013] All M first symbols are flexible symbols;

[1014] The M first symbols include uplink symbols and flexible symbols;

[1015] The M first symbols include uplink and downlink symbols;

[1016] The M first symbols include flexible symbols and downlink symbols;

[1017] The M first symbols include uplink symbols, downlink symbols, and flexible symbols.

[1018] Condition 8.2: The M first symbols include symbols used by the first network device to receive the first uplink signal.

[1019] In some embodiments, the first uplink signal is an uplink signal sent by the terminal device to the first network device. Condition 8.2 means that there is an overlap between the M first symbols and the time domain resources of the first network device for receiving the first uplink signal, that is, at least one of the M first symbols is configured to receive the first uplink signal.

[1020] Step S4202: The first network device cancels the transmission of the first sensing signal.

[1021] In some embodiments, the device configured to receive the first sensing signal can be, for example, one of the following: a terminal device, a first network device, or a second network device. If the device configured to receive the first sensing signal is a first network device, the corresponding sensing mode is TRP monostatic, as shown in the example in Figure 1e(2); if the device configured to receive the first sensing signal is a terminal device, the corresponding sensing mode is TRP-UE bistatic, as shown in the example in Figure 1e(4); if the device configured to receive the first sensing signal is a second network device, the corresponding sensing mode is TRP-TRP bistatic, as shown in the example in Figure 1e(3).

[1022] If M first symbols satisfy conditions 8.1 to 8.2 above, the first network device cancels the transmission of the first sensing signal. In some embodiments, terms such as "the first network device cancels the transmission of the first sensing signal," "the first network device does not expect this to happen," and "an error occurs" can be used interchangeably.

[1023] Regarding condition 8.1 above, the first network device can cancel sending the first sensing signal in the following manner:

[1024] All M first symbols are uplink symbols, and the first network device cancels the transmission of the first sensing signal;

[1025] All M first symbols are flexible symbols, and the first network device cancels the transmission of the first sensing signal;

[1026] The M first symbols include uplink symbols and flexible symbols, and the first network device cancels the transmission of the first sensing signal;

[1027] The M first symbols include downlink symbols and flexible symbols, and the first network device cancels the transmission of the first sensing signal;

[1028] The M first symbols include uplink symbols and downlink symbols, and the first network device cancels the transmission of the first sensing signal;

[1029] The M first symbols include uplink symbols, downlink symbols, and flexible symbols, and the first network device cancels the transmission of the first sensing signal.

[1030] Regarding condition 8.2 above, the M first symbols include symbols used by the first network device to receive the first uplink signal, and the first network device cancels the transmission of the first sensing signal.

[1031] In some embodiments, if the M first symbols include symbols for the first network device to receive the first uplink signal, the first network device may also determine whether to cancel sending the first sensing signal based on the signal type of the first uplink signal.

[1032] For example, if the M first symbols include symbols for the first network device to receive the first uplink signal, and the first uplink signal is a sensing signal, then the first network device cancels the transmission of the first sensing signal; if the M first symbols include symbols for the first network device to receive the first uplink signal, and the first uplink signal is a sensing signal, and the device configured to receive the first sensing signal is not the first network device (i.e., not in single-site sensing mode), then the first network device cancels the transmission of the first sensing signal.

[1033] The communication method involved in the embodiments of this disclosure may include at least one of steps S4201 to S4202. For example, step S4202 may be implemented as a standalone embodiment, but is not limited thereto.

[1034] In some embodiments, step S4201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[1035] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[1036] Referring to Figure 4c, which is an exemplary interactive schematic diagram of a communication method provided in this embodiment of the present disclosure. As shown in Figure 4c, the communication method includes the following steps:

[1037] In step S4301, the first network device processes the first sensing signal using at least one of the M first symbols. This processing involves sending the first sensing signal or canceling the transmission of the first sensing signal using at least one first symbol.

[1038] The M first symbols are symbols used by the first network device to transmit a first sensing signal. In some embodiments, the first network device transmits a first sensing signal on at least one first symbol if the M first symbols satisfy at least one of the following conditions: the M first symbols include downlink symbols and / or flexible symbols; the M first symbols include symbols used by the first network device to receive a first uplink signal.

[1039] In some embodiments, optional implementations of step S4301 can be found in optional implementations of steps S4101 and S4102 in FIG4a, as well as other related parts in the embodiments involved in FIG4a, which will not be repeated here.

[1040] In some embodiments, the first network device cancels the transmission of the first sensing signal if at least one of the following conditions is met by the M first symbols: the M first symbols include uplink symbols and / or flexible symbols; the M first symbols include symbols for the first network device to receive the first uplink signal.

[1041] In some embodiments, optional implementations of step S4301 can be found in optional implementations of steps S4201 and S4202 in FIG4b, as well as other related parts in the embodiments involved in FIG4b, which will not be repeated here.

[1042] In step S4302, the first network device processes the second sensing signal using at least one of the N second symbols. This processing involves sending the second sensing signal or canceling the sending of the second sensing signal using at least one second symbol. The second sensing signal is the sensing signal adjacent to the first sensing signal among the sensing signals transmitted by the configured first network device.

[1043] The N second symbols are symbols used by the first network device to transmit a second sensing signal. In some embodiments, the first network device transmits a second sensing signal on at least one second symbol if the N second symbols satisfy at least one of the following conditions: the N second symbols include downlink symbols and / or flexible symbols; the N second symbols include symbols used by the first network device to receive a first uplink signal.

[1044] In some embodiments, the process of the first network device sending a second sensing signal through at least one second symbol is similar to the process of the first network device sending a first sensing signal through at least one first symbol. For details, please refer to the optional implementations of steps S4101 and S4102 in FIG4a, as well as other related parts in the embodiments involved in FIG4a, which will not be repeated here.

[1045] In some embodiments, the first network device cancels the transmission of the second sensing signal if at least one of the following conditions is met by the N second symbols: the N second symbols include uplink symbols and / or flexible symbols; the N second symbols include symbols for the first network device to receive the first uplink signal.

[1046] In some embodiments, the process of the first network device canceling the transmission of the second sensing signal is similar to the process of the first network device canceling the transmission of the first sensing signal. For details, please refer to the optional implementation of steps S4201 and S4202 in FIG4b, and other related parts in the embodiments involved in FIG4b, which will not be repeated here.

[1047] In step S4303, the first network device determines whether a first event has occurred. The first event is an event in which the phase of the first sensing signal and the phase of the second sensing signal are interrupted.

[1048] In some embodiments, the first event is an event that causes an interruption in the phase of the first sensing signal and the second sensing signal during the process of the first network device transmitting the first sensing signal and transmitting the second sensing signal.

[1049] In some embodiments, it should be noted that the first sensing signal and the second sensing signal are two adjacent sensing signals that the configured first network device needs to send. Regarding the first sensing signal, the first network device may send the first sensing signal or cancel sending it; similarly, regarding the second sensing signal, the first network device may send the second sensing signal or cancel sending it. That is, the first sensing signal is not necessarily ultimately sent by the first network device, and the second sensing signal is not necessarily ultimately sent by the first network device.

[1050] In some embodiments, for two consecutive sensing signals (i.e., a first sensing signal and a second sensing signal) transmitted by the configured first network device, the first event includes at least one of the following 9.1 to 9.6:

[1051] 9.1 The first time-domain resources between M first symbols and N second symbols satisfy the first condition.

[1052] Among them, M first symbols are used for the first network device to send the first sensing signal, and N second symbols are used for the first network device to send the second sensing signal.

[1053] The first time-domain resource is the time-domain resource between M first symbols and N second symbols. The first time-domain resource may include one or more symbols, or one or more time slots.

[1054] For example, if M first symbols are OS#5-13 of time slot #0 and N second symbols are OS#0-5 of time slot #2, then the time-domain resources between the M first symbols and the N second symbols include time slot #1; if M first symbols are OS#0-5 of time slot #0 and N second symbols are OS#10-13 of time slot #0, then the time-domain resources between the M first symbols and the N second symbols include OS#6-9 of time slot #0.

[1055] In some embodiments, the first condition includes at least one of the following 9.1a to 9.1e:

[1056] 9.1a. The first time domain resources include uplink time slots.

[1057] In some embodiments, the first network device may configure a first time domain resource as an uplink timeslot. For example, the first time domain resource is timeslot #1, and the first network device configures timeslot #1 as an uplink timeslot using tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. Here, the uplink timeslot is a timeslot used by the first network device for uplink signal transmission. When the first time domain resource includes an uplink timeslot, the first time domain resource satisfies a first condition.

[1058] 9.1b. The first time domain resources include symbols used by the first network device to receive uplink signals.

[1059] In some embodiments, if a first network device is configured to receive uplink signals on a certain time domain resource, and the time domain resource overlaps with a first delay resource, then the first time domain resource satisfies the first condition. For example, if the first time domain resource includes OS#6-9 of time slot #0, and the first network device is configured to receive uplink signals on OS#9-13 of time slot #0, then since the first time domain resource includes OS#9 of time slot #0, and OS#9 of time slot #0 is a symbol used by the first network device to receive uplink signals, the first time domain resource satisfies the first condition.

[1060] 9.1c. The first time domain resources include symbols used by the first network device to listen for uplink signals.

[1061] In some embodiments, if a first network device is configured to listen for uplink signals on a certain time-domain resource, and the time-domain resource overlaps with a first delay resource, then the first time-domain resource satisfies a first condition. In some embodiments, the uplink signals listened to by the first network device may include, for example, PUSCH, etc.

[1062] 9.1d. The number of symbols included in the first time-domain resource is greater than or equal to the first quantity.

[1063] For a detailed description of 9.1d, please refer to the optional implementation of 3.1d in step S2304 of Figure 2c, as well as other related parts in the embodiments involved in Figure 2c, which will not be repeated here.

[1064] 9.1e. The first time domain resources include symbols used by the first network device to transmit downlink signals.

[1065] In some embodiments, if a first network device is configured to transmit downlink signals on a certain time domain resource, and the time domain resource overlaps with a first delay resource, then the first time domain resource satisfies the first condition. For example, if the first time domain resource includes OS#6-9 of time slot #0, and the first network device is configured to transmit downlink signals on OS#9-13 of time slot #0, then since the first time domain resource includes OS#9 of time slot #0, and OS#9 of time slot #0 is a symbol used by the first network device to transmit downlink signals, the first time domain resource satisfies the first condition.

[1066] The above embodiments introduce a first condition. When the first time domain resources meet the first condition, the first network device can determine that a first event has occurred, namely, an event that causes the phase of the first sensing signal and the second sensing signal to be interrupted during the process of the first network device sending the first sensing signal and sending the second sensing signal.

[1067] 9.2 The first network device cancels the transmission of the first sensing signal.

[1068] In some embodiments, the first network device may transmit a first sensing signal on at least one of the M first symbols, or it may cancel transmitting the first sensing signal. For example, if the first network device satisfies at least one of conditions 8.1 to 8.2 above, the first network device cancels transmitting the first sensing signal.

[1069] If the first network device cancels the transmission of the first sensing signal, the first sensing signal will have no phase. In this case, the phases of the first sensing signal and the second sensing signal will be interrupted.

[1070] 9.3 The first network device cancels the transmission of the second sensing signal.

[1071] In some embodiments, the first network device may transmit a second sensing signal on at least one of the N second symbols, or it may cancel transmitting the second sensing signal. For example, the first network device cancels transmitting the second sensing signal if the N second symbols satisfy at least one of the following conditions: the N second symbols include uplink symbols and / or flexible symbols; the N second symbols include symbols used by the first network device to receive the first uplink signal.

[1072] If the first network device cancels the transmission of the second sensing signal, the second sensing signal will not have a phase. In this case, the phase of the first sensing signal and the second sensing signal will be interrupted.

[1073] 9.4 The TCI state of the first sensing signal is different from that of the second sensing signal.

[1074] For details on 9.4, please refer to the optional implementation of 3.4 in step S2304 of Figure 2c, as well as other related parts in the embodiments involved in Figure 2c, which will not be repeated here.

[1075] 9.5 The power parameters of the first sensing signal and the second sensing signal are different.

[1076] For details on 9.5, please refer to the optional implementation of 3.5 in step S2304 of Figure 2c, as well as other related parts in the embodiments involved in Figure 2c, which will not be repeated here.

[1077] 9.6 The frequencies of the first sensing signal and the second sensing signal are different.

[1078] The fact that the frequencies of the first sensing signal and the second sensing signal are different indicates that there is a frequency hopping between the first sensing signal and the second sensing signal. In this case, the phases of the first sensing signal and the second sensing signal are discontinuous.

[1079] In some embodiments, considering that phase continuity helps improve sensing performance, some or all of the events in the first event can be specially processed to avoid affecting the phase continuity of the first sensing signal and the second sensing signal.

[1080] For example, with respect to item 9.1a in the first event above, if the first time domain resource includes an uplink time slot: the first network device will not switch from downlink transmission to receiving uplink signals in the first time domain resource, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1081] For example, with respect to item 9.1b of the first event above, if the first time domain resource includes symbols for the first network device to receive uplink signals: the first network device cancels receiving uplink signals to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1082] For example, with respect to item 9.1c in the first event above, if the first time domain resource includes symbols for the first network device to listen to uplink signals: the first network device cancels listening to uplink signals to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1083] For example, regarding item 9.1d in the first event above, if the number of symbols included in the first time domain resource is greater than or equal to the first number: the first network device will not send or receive signals in the first time domain resource to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1084] For example, regarding item 9.1e of the first event above, if the first time domain resource includes symbols for the first network device to transmit downlink signals: the first network device cancels the transmission of downlink signals in the first time domain resource to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1085] For example, regarding item 9.2 of the first event above, if the first network device meets the relevant conditions for canceling the transmission of the first sensing signal: when the first sensing signal and the second sensing signal need to maintain phase continuity, the first network device does not cancel the transmission of the first sensing signal, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1086] For example, regarding item 9.3 of the first event above, if the first network device meets the relevant conditions for canceling the transmission of the second sensing signal: when the first sensing signal and the second sensing signal need to maintain phase continuity, the first network device does not cancel the transmission of the second sensing signal, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1087] For example, regarding item 9.4 of the first event above, if the TCI state of the first sensing signal and the TCI state of the second sensing signal are different: the first network device cancels the TCI switching to ensure that the TCI states of the first sensing signal and the second sensing signal are the same, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1088] For example, regarding item 9.5 of the first event above, if the power parameters of the first sensing signal and the second sensing signal are different: the first network device cancels the power parameter adjustment to ensure that the power parameters of the first sensing signal and the second sensing signal are the same, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1089] For example, regarding item 9.6 of the first event above, if the frequency of the first sensing signal and the frequency of the second sensing signal are different: the first network device cancels frequency hopping to ensure that the frequencies of the first sensing signal and the second sensing signal are the same, so as to ensure the phase continuity of the first sensing signal and the second sensing signal.

[1090] In step S4304, when the first event occurs, the first network device transmits a first reference signal on P third symbols and a second reference signal on Q fourth symbols; the time slots where the M first symbols are located are the same as the time slots where the P third symbols are located, and the first reference signal is used to determine the phase of the first sensing signal; the time slots where the N second symbols are located are the same as the time slots where the Q fourth symbols are located, and the second reference signal is used to determine the phase of the second sensing signal.

[1091] In some embodiments, the occurrence of the first event is unpredictable, and the first network device may by default send the first reference signal on P third symbols and send the second reference signal on Q fourth symbols.

[1092] In the event of the first event, the first network device can determine that the phase of the first sensing signal and the phase of the second sensing signal have been interrupted. Then, the first network device can determine the phase of the first sensing signal and the phase of the second sensing signal by sending the first reference signal and the second reference signal.

[1093] Specifically, the first network device transmits a first reference signal on P third symbols, wherein the P third symbols and M first symbols reside in the same time slot. The device configured to receive the first sensing signal, the device configured to receive the first reference signal, the device configured to receive the second sensing signal, and the device configured to receive the second reference signal are all the same device.

[1094] In some embodiments, the device configured to receive the above signal can be, for example, one of the following: a first network device, a second network device, with the second network device being used as an example in FIG4.

[1095] In some embodiments, there are overlapping symbols between the P third symbols and the M third symbols.

[1096] In some embodiments, there are no overlapping symbols between the P third symbols and the M third symbols.

[1097] In some embodiments, the subcarrier in which the first reference signal is located overlaps with the subcarrier in which the first sensing signal is located.

[1098] In some embodiments, the subcarrier in which the first reference signal is located and the subcarrier in which the first sensing signal is located do not overlap.

[1099] In some embodiments, the RB where the first reference signal is located and the RB where the first sensing signal is located overlap.

[1100] In some embodiments, the RB where the first reference signal is located and the RB where the first sensing signal is located do not overlap.

[1101] Specifically, the first network device transmits a second reference signal on Q fourth symbols, wherein the time slots containing N second symbols are the same as the time slots containing Q fourth symbols.

[1102] In some embodiments, there are overlapping symbols between the Q fourth symbols and the N second symbols.

[1103] In some embodiments, there are no overlapping symbols between the Q fourth symbols and the N second symbols.

[1104] In some embodiments, the subcarrier in which the second reference signal is located overlaps with the subcarrier in which the second sensing signal is located.

[1105] In some embodiments, the subcarrier in which the second reference signal is located and the subcarrier in which the second sensing signal is located do not overlap.

[1106] In some embodiments, the RB where the second reference signal is located overlaps with the RB where the second sensing signal is located.

[1107] In some embodiments, the RB containing the second reference signal and the RB containing the second sensing signal do not overlap.

[1108] In some embodiments, the first reference signal is a PTRS. The PTRS can be used to accurately track and correct phase changes of the first sensing signal. In some embodiments, the second reference signal is a PTRS. The PTRS can be used to accurately track and correct phase changes of the second sensing signal.

[1109] In step S4305, the first network device determines whether the phase of the first sensing signal and the phase of the second sensing signal are continuous based on whether the first event has occurred.

[1110] Since the first network device is the transmitting device for both the first and second sensing signals, if the first event does not occur, the phases of the first and second sensing signals transmitted by the first network device are continuous. If the first event occurs, the phases of the first and second sensing signals are discontinuous.

[1111] In step S4306, the first network device sends a first indication message to the second network device. The second network device is configured to receive a first sensing signal and a second sensing signal. The first indication message is used to indicate whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[1112] In some embodiments, step S4306 is an optional step. If the device configured to receive the first sensing signal and the second sensing signal is a first network device, then step S4306 does not need to be executed.

[1113] In some embodiments, if the device configured by the first network device to receive the first sensing signal and the second sensing signal is the second network device, the first network device sends a first indication information to the second network device. The first indication information is used to indicate whether the phase of the first sensing signal and the phase of the second sensing signal are continuous.

[1114] In some embodiments, if the device configured by the first network device for receiving the first sensing signal and the second sensing signal is a second network device, the sensing network element can send first indication information to the second network device. The first indication information indicates whether the phases of the first sensing signal and the second sensing signal are continuous. For example, the first network device can send the first indication information to the sensing network element, and then the sensing network element can send the first indication information to the second network device.

[1115] The communication method involved in the embodiments of this disclosure may include at least one of steps S4301 to S4306. For example, steps S4301+S4302+S2403+S4304 can be implemented as an independent embodiment, and steps S4301+S4302+S2403+S4304+S4305 can be implemented as an independent embodiment, but are not limited thereto.

[1116] In some embodiments, steps S4304, S4305, and S4306 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[1117] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
