[0220] Figure 1B is a schematic diagram illustrating sensing modes according to embodiments of the present disclosure. As shown in Figure 1B, the application scenarios for ISCA technology include the following sensing modes:
[0221] (a) TRP (Transmission and Receiving Point) - mono-static mode: The base station transmits and receives signals on its own. The base station sends sensing signals, and after the sensing signals are reflected by the object being measured, the base station receives the reflected waves and uses the reflected waves to sense the object being measured.
[0222] (b) TRP-TRP-bistatic (dual-station) mode: Base station A transmits and base station B receives. Base station A sends a sensing signal, and after the sensing signal is reflected by the object being measured, base station B receives the reflected wave and uses the reflected wave to sense the object being measured.
[0223] (c) TRP-UE (User Equipment)-bistatic mode: the base station transmits and the UE receives. The base station sends a sensing signal, and after the sensing signal is reflected by the object under test, the UE receives the reflected wave and the UE senses the object under test based on the reflector wave.
[0224] (d) UE-TRP-bistatic mode, UE transmits and base station receives. UE sends sensing signals, and after the sensing signals are reflected by the object under test, the base station receives the reflected waves and uses the reflected waves to sense the object under test.
[0225] (e) UE-mono-static mode, UE self-transmits and receives signals. The UE sends a sensing signal, and after the sensing signal is reflected by the object under test, the UE receives the reflected wave and the UE senses the object under test based on the reflected wave.
[0226] (f) UE-UE-bistatic mode, UE-A transmits and UE-B receives. UE-A transmits a sensing signal, which is reflected by the object under test. UE-B receives the reflected wave and uses the wave from the reflector to sense the object under test.
[0227] In some embodiments, the use cases of ISCA technology also include a multi-station sensing mode, in which a transmitting end sends a sensing signal, and after the sensing signal is reflected by the object being measured, a set of multiple stations senses the object based on the reflected wave. For example, the multi-station sensing mode may include the following:
[0228] (g) TRP-TRP-multi-static mode: Base station A sends a sensing signal. After the sensing signal is reflected by the object being measured, the reflected wave is received by base station set #1. Base station set #1 includes one or more base stations. Each base station in base station set #1 senses the object being measured based on the reflected wave.
[0229] (h) TRP-UE-multi-static mode, base station transmits and UE receives. The base station sends a sensing signal. After the sensing signal is reflected by the object under test, UE set #1 receives the reflected wave. UE set #1 contains one or more UEs. Each UE in UE set #1 senses the object under test based on the reflected wave.
[0230] (i) UE-TRP-multi-static mode, UE transmits and base stations receive. The UE sends a sensing signal. After the sensing signal is reflected by the object being measured, the base station set #2 receives the reflected wave. The base station set #2 includes one or more base stations. Each base station in the base station set #2 senses the object being measured based on the reflected wave.
[0231] (j) UE-UE-multi-static mode. UE-A sends a sensing signal. After the sensing signal is reflected by the object under test, UE set #2 receives the reflected wave. UE set #2 contains one or more UEs. Each UE in UE set #2 senses the object under test based on the reflected wave.
[0232] In some embodiments, the symbol format used to carry signaling and communication information in a communication system can be flexibly configured or indicated, and the time-frequency resources where signal transmission occurs can be flexibly configured or indicated based on configuration information. Therefore, conflicts may arise between the symbol format and the signal transmission direction, or between two time-frequency resources where there is overlap or non-overlapping sensing signal A and other signals B, resulting in conflicts in the transmission direction. This embodiment proposes a communication method to standardize the symbol format of the symbol containing sensing signal A, address conflicts between the symbol format and the transmission direction of sensing signal A, and address conflicts between the transmission directions of sensing signal A and other signals B, ensuring transmission stability during signal interaction.
[0233] In some embodiments, in UE-mono-static single-site sensing mode, the UE needs to transmit sensing signals on the same symbol, that is, send sensing signals based on the same symbol format and receive sensing signals reflected from the target based on the same symbol format. Considering the differences between the sending and receiving behavior of sensing signals and communication in single-site sensing mode, as well as the urgency and importance of sensing signals, the conflict handling of sensing signals differs from the handling of other communication signals. This embodiment proposes a communication method to standardize the relevant processing behavior in the sensing signal conflict handling process.
[0234] In some embodiments, when there is a conflict between the DL signal and the SFI-D / U / F symbol format, the DL signal reception behavior is determined using the processing methods in Table 1 below:
[0235] In Table 1 above, RRC (Radio Resource Control)-D (PDSCH (Physical Downlink Shared Channel) / CSI-RS (Channel State Information-Reference Signal)) is the PDSCH signal or CSI-RS signal configured by the network side to the UE based on RRC signaling.
[0236] SFI (Slot Format Indicator)-D indicates that the SFI field in DCI (Downlink Control Information)-format 2-0 indicates that the symbol format is downlink symbol; SFI-U indicates that the SFI indicates that the symbol format is uplink symbol; SFI-F indicates that the SFI indicates that the symbol format is flexible symbol. When the symbol configured by SFI-F does not transmit data, it can be used as a time domain protection interval, and no data is transmitted on that symbol.
[0237] PRS (Positioning Reference Signal) is a signal used for positioning reference; RRC-D (PRS) indicates the PRS configured by the network side to the UE based on RRC signaling;
[0238] Dynamic-D is used for DCI signaling to indicate the reception of DL signals, and Dynamic-U is used for DCI signaling to indicate the transmission of UL signals. For example, Dynamic-D(PDSCH / CSI-RS) indicates that the DCI signaling indicates that the UE receives PDSCH / CSI-RS in the symbol set, and Dynamic-D(PRS) indicates that the DCI signaling indicates that the UE receives PRS in the symbol set.
[0239] Type 0-PDCCH (Physical Downlink Control Channel)-CSS (Common Search Space)-set is a set of PDCCH common search spaces used to transmit system messages (e.g., SIB1 (System Information Block 1)). It allows UEs to jointly monitor PDCCH within the cell in order to receive and decode system information.
[0240] For example, based on Table 1 above, the network side in this embodiment is configured with dynamic signaling DCI2-0. This dynamic signaling DCI2-0 is used to indicate the symbol format of the first symbol set in which the sensed signal resides. After the terminal successfully receives this DCI2-0 signaling, it determines the reception of the current sensed signal. In this embodiment, when there is a conflict between the DL signal and the SFI-D / F / U symbol format, the processing method in Table 1 above is used for signal reception.
[0241] Figure 1C is a schematic diagram illustrating the symbol format conflict handling between the DL signal and the SFI indication according to an embodiment of the present disclosure. As shown in Figure 1C, the symbol format in time slot #3 is as follows: OS (OFDM symbol, OFDM (Orthogonal Frequency Division Multiplexing) symbol) #0-5 are configured as SFI-DL, OS #6-8 are configured as SFI-F, and OS #9-13 are configured as SFI-UL.
[0242] (1) The symbol set of RRC-D#1 is in OS#1-5 of time slot #3. If RRC-D#1 configures the UE to receive PDSCH / CSI-RS / PRS in the symbol set, and the symbol format of OS#1-5 in time slot #3 is SFI-DL, then based on 2-1-1 and 2-2-1 in Table 1 above, the UE receives RRC-D#1 (PDSCH / CSI-RS / PRS).
[0243] (2) The symbol set of RRC-D#2 is in OS#1-8 of time slot #3. If RRC-D#2 configures the UE to receive PDSCH / CSI-RS in the first symbol set, and the symbol format of OS#1-5 in time slot #3 is SFI-DL and the symbol format of OS#6-8 is SFI-F, then based on 2-1-2 in Table 1 above, the reception of RRC-D#2 is cancelled; if RRC-D#2 configures the UE to receive PRS in the first symbol set, and the symbol format of OS#1-5 in time slot #3 is SFI-DL and the symbol format of OS#6-8 is SFI-F, then based on 2-2-1 in Table 1 above, the UE receives RRC-D#2.
[0244] (3) The symbol set of RRC-D#3 is in OS#1-10 of time slot #3. If RRC-D#3 configures the UE to receive PDSCH / CSI-RS / PRS in the first symbol set, and in the symbol format of time slot #3, the symbol format of OS#1-5 is SFI-DL, the symbol format of OS#6-8 is SFI-F, and the symbol format of OS#9-10 is SFI-UL, according to 2-1-2 and 2-2-2 in Table 1 above, the UE cancels the reception of RRC-D#3;
[0245] (4) The symbol set of Dynamic-D#1 is in OS#1-8 of time slot #3. In the symbol format of time slot #3, the symbol format of OS#1-5 is SFI-DL, and the symbol format of OS#6-8 is SFI-F. According to 6-1 in Table 1 above, the UE receives Dynamic-D#1.
[0246] (5) The first symbol set of Dynamic-D#2 is in OS#1-10 of time slot #3. In the symbol format of time slot #3, the symbol format of OS#1-5 is SFI-DL, the symbol format of OS#6-8 is SFI-F, and the symbol format of OS#9-10 is SFI-UL. According to 6-2 in Table 1 above, the UE does not expect this situation to occur. If the UE determines that this situation has occurred, the UE will determine it as an error. For example, when the UE determines it as an error, the UE can cancel receiving Dynamic-D#2. When the UE determines it as an error, it can feed back the current error information to the network side to instruct the network side to re-indicate the symbol based on the transmitted Dynamic-D#2.
[0247] (6) The symbol set of PDCCH#1 is in OS#3-5 of time slot #3. The symbol format of OS#3-5 is SFI-DL. According to 14-1 in Table 1 above, the UE receives PDCCH#1.
[0248] (7) The symbol set of PDCCH#2 is in OS#7-9 and OS#6-8 of time slot #3. The symbol format is SFI-F and the symbol format of OS#9 is SFI-UL. According to 14-3 in Table 1 above, the UE cancels the reception of PDCCH#2.
[0249] (8) The symbol set corresponding to Type-0 PDCCH CCS set is in OS#7-9 and OS#6-8 of time slot #3. The symbol format is SFI-F, and the symbol format of OS#9 is SFI-UL. According to 13-2 in Table 1 above, the UE does not expect this situation to occur, and the UE judges it as an error.
[0250] Figure 1D is a schematic diagram illustrating the handling of conflicts between DL signals and semi-statically configured symbol formats according to an embodiment of this disclosure. In this embodiment, the network side is configured with dynamic signaling DCI2-0, which is used to indicate the symbol format of the first symbol set in which the sensed signal is located. The terminal fails to detect the DCI2-0 signaling. When there is a conflict between the DL signal and the semi-statically configured symbol format, the signal reception is performed using the processing method in Table 2 below.
[0251] Semi-D is a semi-static configuration symbol format with downlink symbols, Semi-U is a semi-static configuration symbol format with uplink symbols, and Semi-F is a semi-static configuration symbol format with flexible symbols or no semi-static configuration. For example, the configuration methods of Semi-D / U include: (1) Tdd-UL-DL-ConfigurationCommon is configured as a DL symbol or a UL symbol; (2) Tdd-UL-DL-ConfigurationCommon or Tdd-UL-DL-ConfigurationDedicated is configured as a DL symbol or a UL symbol. The configuration methods of Semi-F include: (1) Tdd-UL-DL-ConfigurationCommon is configured as an F symbol; (2) Tdd-UL-DL-ConfigurationCommon or Tdd-UL-DL-ConfigurationDedicated is configured as an F symbol; (3) There is no Tdd-UL-DL-ConfigurationCommon or Tdd-UL-DL-ConfigurationDedicated configuration in the UE.
[0252] In Table 2 above, Any-D (PDCCH, PDSCH, or CSI-RS) is used for DCI signaling to dynamically instruct the UE to receive PDCCH, PDSCH, or CSI-RS signals in the symbol set; Any-D (PRS) is used for DCI signaling to dynamically instruct the UE to receive PRS in the symbol set.
[0253] For example, as shown in Figure 1D, in time slot #3, the symbol format for different time slot positions is as follows: OS#0-5 are configured as Semi-D, OS#6-8 are configured as Semi-F, and OS#9-13 are configured as Semi-U.
[0254] (1) The symbol set of DL#1 is in OS#6-8 of time slot #3. If RRC-D configures the UE to receive PDSCH / CSI-RS in the symbol set, and OS#6-8 in the symbol format of time slot #3 is configured as Semi-F, then based on 2-1-3 in Table 2 above, the UE cancels receiving DL#1; if RRC-D configures the UE to receive PRS / PDCCH in the symbol set, or Dynamic-D configures the UE to receive PDSCH / CSI-RS in the symbol set, and OS#6-8 in the symbol format of time slot #3 is configured as Semi-F, then according to 2-2-3, or 14-2, or 6-3 in Table 2 above, the UE receives DL#1;
[0255] (2) The symbol set of DL#2 is in OS#7-9 of time slot #3. In the symbol format of time slot #3, OS#7-8 is configured as Semi-F and OS#9 is configured as Semi-U. If Any-D is configured for the UE to receive PDCCH, PDSCH or CSI-RS in the symbol set, according to 3-1 in Table 2 above, the UE cancels the reception of DL#2 on the OS#7-9 symbol. If Any-D is configured for the UE to receive PRS in the symbol set, according to 3-1-2 in Table 2 above, the UE cancels the reception of DL#2 on the OS#9 symbol.
[0256] Figure 1E is a schematic diagram illustrating conflict handling between UL signals and semi-static configuration symbol formats according to an embodiment of this disclosure. When a conflict exists between the UL signal and the semi-static configuration symbol format, the signal transmission is performed using the processing method in Table 3 below.
[0257] In Table 3 above, SRS (Sounding Reference Signal) can be applied to channel measurement, beam management, MIMO (Multiple Input Multiple Output) transmission, link adaptation, etc.; the first symbol set is the symbol set where the UL signal is located, and the first time-domain resource is the time-domain resource within TProc.2 symbols after the last symbol of the CORESET (Control Resource Set) where the dynamic signaling DCI 2-0 is located. Scheme 1-1-3 above states that if the first time-domain resource overlaps with the first symbol set, the UE does not want to cancel the UL signal transmission; otherwise, the UE cancels the UL signal transmission. Scheme 1-1-4 above states that if the UE does not want to cancel the transmission of the UL signal on the symbols where the first time-domain resource overlaps with the first symbol set, the UE cancels the transmission of the UL signal on the remaining symbols in the first symbol set.
[0258] For example, as shown in Figure 1E, in time slot #3, the symbol format for different time slot positions is as follows: OS#0-1 is configured as Semi-D, OS#2-13 is configured as Semi-F, and the first time domain resource includes: OS#2-13 of time slot #2 and OS#0-3 of time slot #3.
[0259] (1) If the symbol set of UL#1 is in OS#2-11 of time slot #3, then the symbol set of UL#1 is Semi-F;
[0260] If Dynamic-U is configured to send PUCCH / PUSCH / PRACH / SRS in the symbol set, the UE sends UL#1 according to 7-3 in Table 3 above;
[0261] If enableConfigured-UL is configured in the UE, the RRC-U configures the UE to send PUCCH / PUSCH / PRACH / SRS in the symbol set. According to 1-4-3 in Table 3 above, the UE sends UL#1.
[0262] If enableConfigured-UL is not configured in the UE, there is an overlap between the first time domain resource and the first symbol set. The symbol format corresponding to this overlap is OS#2-3 in time slot #3: (1) When RRC-U configures the UE to send PUCCH / PUSCH / PRACH in the symbol set, if the UE does not support partial transmission capability, the UE sends UL#1; if the UE supports partial transmission capability, the UE does not expect to cancel sending UL#1 on OS#2-3, and the UE cancels sending UL#1 on OS#4-11. For example, the UE sends UL#1 on OS#2-3 and cancels sending UL#1 on OS#4-11; (2) When RRC-U configures the UE to send SRS in the symbol set, the UE does not expect to cancel sending UL#1 on time slot OS#2-3, and the UE cancels sending UL#1 on OS#4-11.
[0263] (2) If the symbol set of UL#2 is in OS#4-13 of time slot #3, then the symbol set OS#4-13 of UL#2 is configured as Semi-F;
[0264] If Dynamic-U is configured to send PUCCH / PUSCH / PRACH / SRS in the symbol set, the UE sends UL#2 based on 7-3 in Table 3 above;
[0265] If the UE is configured with enableConfigured-UL, the RRC configures the UE to send PUCCH / PUSCH / PRACH / SRS in the symbol set. Based on 1-4-3 in Table 3 above, the UE sends UL#2.
[0266] If the UE is not configured to enableConfigured-UL, there are no overlapping symbols between the first time domain resources and the first symbol set; (1) RRC-U configures the UE to send PUCCH / PUSCH / PRACH in the symbol set. When the UE does not support partial transmission capability, the UE cancels the transmission of UL#2; when the UE supports partial transmission capability, the UE cancels the transmission of UL#2; (2) RRC-U configures the UE to send SRS in the symbol set. The UE cancels the transmission of UL#2.
[0267] (3) The symbol set of UL#3 is in OS#0-7 of time slot #3. Then the symbol set of UL#2, OS#0-1, is configured as Semi-D and OS#2-7 is configured as Semi-F. According to 4-1 in Table 3 above, the UE cancels the transmission of UL#3.
[0268] In some embodiments, when configuring the conflict handling method, the need for the UE to transmit and receive sensing signals on the same symbol is not considered in mono-static UE mode, and the aforementioned conflict handling criteria do not consider the urgency or importance difference between sensing signals and communication signals. Therefore, this embodiment proposes a communication method that enables the UE to transmit (including transmit or receive) sensing signals on the same DL symbol, UL symbol, or F symbol in mono-static UE mode, thereby increasing the priority and importance of sensing signals and ensuring that sensing signals can be transmitted in most conflict situations, including sensing signal transmission or reception in the UE and in the network device.
[0269] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:
[0270] In step S2101, network device 102 sends first information to terminal 101.
[0271] In some embodiments, the first information is used to indicate the time-frequency resource allocation in one or more time slot sets. For example, the first information indicates that in time slot #1, OS#1-3 are DL symbols, and the UE receives communication data sent by the network device based on the time-frequency resources of OS#1-3; OS#4-5 are F symbols; and OS#6-9 are UL symbols, and the UE sends communication data to the network device based on the time-frequency resources of OS#6-9.
[0272] For example, the first piece of information is used to indicate the symbol category information of each symbol. The symbol category includes DL symbols, UL symbols, F symbols, etc. DL symbols are used to carry communication data sent from the network device to the UE, UL symbols are used to carry communication data sent from the UE to the network device, and the time and frequency resources corresponding to F symbols are configured through higher-layer signaling or dynamic signaling for uplink data transmission or downlink data transmission in the communication system.
[0273] For example, the first information is used to indicate the time-frequency resource information of other signals in the first symbol set. The type of the other signal can be a UL signal, a DL signal, a UL sensing signal, or a DL sensing signal. The network device uses the first information to instruct the first symbol set to transmit the other signal, wherein the transmission type of the other signal can be the same as or opposite to the transmission direction of the sensing signal.
[0274] For example, the first information can be configured by higher layers or dynamically via signaling. Network devices configure and manage radio resources in the communication system through RRC protocols or other higher-layer protocols, or dynamically adjust signaling parameters based on the current communication environment and user needs. Network devices configure time-frequency resources in the UE using the first information.
[0275] In some embodiments, the first information includes symbol category information of each symbol in the first symbol set and / or, the first information includes time-frequency resource information of the sensed signal.
[0276] For example, this embodiment can be applied to sensing signal transmission scenarios in single-site sensing mode and / or multi-site sensing mode. It detects the sensing information of the object under test through the transmission of sensing signals. This sensing information may include the object's speed, direction, distance, position, angle, etc. The single-site sensing mode can include UE mono-static and / or TRP mono-static. In the TRP mono-static sensing transmission scenario, the network device transmits and receives signals automatically. The network device sends a sensing signal to the object under test, and after the sensing signal is reflected by the object, the network device receives the reflected wave and determines the sensing information of the object under test based on the reflected wave. In the UE mono-static sensing transmission scenario, the UE transmits and receives signals automatically. The UE sends a sensing signal to the object under test, and after the sensing signal passes through the object, an echo signal is reflected back to the UE. The UE analyzes this echo signal to determine the sensing information of the object under test. This solution does not limit the processing node of the corresponding echo signal; the echo signal can be analyzed at the network side, terminal side, core network, etc.
[0277] In the aforementioned sensing transmission scenario, there may be a conflict between the transmission direction of the sensing signal and the current symbol type configured by the network device. For example, the UE is configured to send a sensing signal to the network device in OS#3-5 of time slot #2. However, in the current network environment, the network device configures the symbol type of OS#3-6 as DL symbol through dynamic DCI. In this case, the UE needs to send a sensing signal to the network device, and the transmission direction of the sensing signal is an uplink transmission signal from the UE to the network device. This conflict with the current time-frequency resource symbol type of DL symbol, causing a conflict between the transmission direction of the sensing signal and the current time-frequency resource symbol type. Therefore, in this embodiment, the network device sends first information indicating the symbol category of the first symbol set containing the sensing signal, as well as the time-frequency resource of the sensing signal. Based on the first information, the UE determines to process the sensing signal based on the first action.
[0278] In some embodiments, the name of the first information is not limited, and may be, for example, "sensing signal resource configuration information", "symbol category configuration", "symbol category indication information", "time-frequency resource location information for transmitting sensing signals", "time-frequency resource location information for receiving sensing signals", "resource configuration information", "dynamic signaling information", "higher layer configuration", etc.
[0279] In some embodiments, terminal 101 receives first information.
[0280] In step S2102, terminal 101 processes the UL sensing signal based on the first information and the first behavior.
[0281] For example, in this embodiment, conflict handling criteria are configured. Based on the first information UE, different conflict situations are determined, and then different methods are used to process the sensing signal based on the different conflict situations. The processing of the sensing signal includes transmitting the sensing signal, partially transmitting the sensing signal, and canceling the transmission of the sensing signal.
[0282] Similar to the reference configuration in Tables 1, 2 and 3 of the above embodiments, the UE is configured with multiple mapping relationships between multiple situations and multiple first actions. The UE determines the situation information corresponding to the current sensing signal in the configuration relationship based on the first information, and then determines the target first action corresponding to the situation information based on the mapping relationship, thereby processing the sensing signal based on the target first action.
[0283] In some embodiments, the sensing signal includes a UL sensing signal, in which case the UE needs to transmit the UL sensing signal based on the transmission resources of the UL symbol and / or F symbol. Based on the UL sensing signal, the corresponding first action in the UE includes at least one of the following:
[0284] UE cancels sending UL sensing signal;
[0285] UE sends UL sensing signal;
[0286] The UE partially transmits UL sensing signals on the UL symbol and / or F symbol.
[0287] For example, in this embodiment, the UE determines, based on first information, to process the sensing signal according to a first action. The symbol types of the symbols in the first set indicated by the first information are different, and / or the time-frequency resources of the sensing signal corresponding to the first information are different, leading to different processing methods for the sensing signal by the UE. The first action includes: the UE canceling the transmission of the UL sensing signal, the UE transmitting the UL sensing signal, and the UE partially transmitting the UL sensing signal on UL symbols and / or F symbols. For instance, if the UE determines, based on the first information, that all symbols in the first symbol set indicated by the network device are UL symbols, the UE can transmit the sensing signal based on the first information; if the UE determines, based on the first information, that all symbols in the first symbol set indicated by the network device are DL symbols, and the UE determines that the symbol types of the first symbol set conflict with the UL sensing signal, the UE can cancel the transmission of the sensing signal based on the first information; if the UE determines that the symbol types of the first symbol set include UL symbols, F symbols, and DL symbols, the UE determines to partially transmit the UL sensing signal on the non-conflicting symbols, that is, the UE determines, based on the first information, to partially transmit the UL sensing signal on UL symbols and / or F symbols.
[0288] In some embodiments, step S2102 above includes:
[0289] Based on the first information, the UE determines that the symbol category of the UL sensing signal is a UL symbol and sends the UL sensing symbol; or,
[0290] Based on the first information, the UE determines that the symbol category of the UL sensing signal includes at least one DL symbol or F symbol, and cancels the transmission of the UL sensing signal.
[0291] For example, the UE uses pre-configuration to determine the appropriate way to process UL sensing signals based on different first information sent by the network device.
[0292] The processing criteria for UL sensing signals configured in the UE include:
[0293] When the UE determines that the symbol categories of the UL sensing signals are all UL symbols based on the first information, the UE determines that the current transmission of the UL sensing signal matches the symbol category of the current first symbol set. That is, the symbol categories of the first symbol set are all UL transmission resources, and there is no conflict between the transmission of the UL sensing signal and the symbol category. At this time, the UE determines to transmit the UL sensing signal.
[0294] When the UE determines, based on the first information, that the symbol category of the UL sensing signal includes at least one DL symbol or F symbol, the UE considers the time slot resources configured by the current network device to be incorrect and cancels the transmission of the UL sensing signal. Alternatively, the UE may consider it an error case, meaning the UE does not expect this situation to occur. For example, the UE may not expect this situation to occur by considering it an error case and canceling the transmission of the UL sensing signal, or the UE may report the current error case to the network device, which will then reconfigure the time slot resources used for transmitting the UL sensing signal based on this error feedback. In this embodiment, the subsequent actions of the UE in considering it an error case are not limited; the UE can set them based on the current network environment and communication requirements.
[0295] It should be noted that in this embodiment, the condition for the UE to send UL sensing signals is that all symbols of the sensing signals are UL symbols. If the symbol category corresponding to the sensing signal includes at least one other symbol category (e.g., DL symbol and / or F symbol), the transmission of the UL sensing signal is cancelled. This can be understood as the urgency of sending the UL sensing signal in the UE being low at this time. If the transmission direction of the UL sensing signal does not match the symbol of the sensing signal in the UE, the UE does not want this to happen and will cancel the transmission of the UL sensing signal.
[0296] In some embodiments, step S2102 above includes:
[0297] Based on the first information, the UE determines the symbol category of the UL sensing signal to be UL symbol and / or F symbol, and transmits the UL sensing signal; or,
[0298] Based on the first information, the UE determines that the symbol category of the UL sensing signal includes at least one DL symbol, and cancels the transmission of the UL sensing signal.
[0299] For example, the UE determines the symbol category of the UL sensing signal based on the first information. If there is at least one DL symbol in the symbol category of the UL sensing signal, the UE determines that there is a conflict between the current UL sensing signal and the symbol type, and cancels the transmission of the UL sensing signal accordingly. Otherwise, the UE can transmit the UL sensing signal when it determines that the symbol category of the UL sensing signal is UL symbol and / or F symbol based on the first information. For example, the UE can partially transmit the UL sensing signal on UL symbol and / or F symbol.
[0300] It should be noted that the transmission level of the UL sensing signal configured in the UE in this embodiment is higher than that in the above embodiments. If the time slot resource type corresponding to the UL sensing signal in the symbol set indicated by the first information includes at least one DL symbol, the UE does not expect this to happen, or cancels the transmission of the UL sensing signal; if the time slot resource type corresponding to the UL sensing signal in the symbol set indicated by the first information includes UL symbols and / or F symbols, the UE transmits the UL sensing signal.
[0301] In some embodiments, step S2102 above includes:
[0302] Based on the first information, the UE determines that the symbol category of the UL sensing signal includes UL symbol, F symbol and DL symbol, and then sends the UL sensing signal.
[0303] For example, in this embodiment, the UE sends the UL sensing signal when it determines that the symbol category of the UL sensing signal includes UL symbol, F symbol, and DL symbol. That is, the transmission level of the UL sensing signal is high in this embodiment, and the transmission of the UL sensing signal by the UE is urgent in the current network environment. Therefore, the UE sends the UL sensing signal when it determines, based on the first information, that the symbol category of the UL sensing signal includes UL symbol, F symbol, and DL symbol.
[0304] In some embodiments, step S2102 above includes:
[0305] Based on the first information, the UE determines that the symbol category of the UL sensing signal includes UL symbol, F symbol and DL symbol, and partially transmits the UL sensing signal on the UL symbol and / or F symbol.
[0306] For example, when the UE determines that the symbol category of the UL sensing signal includes UL symbol, F symbol and DL symbol according to the first information, in order to ensure the transmission of the UL sensing signal in the UE, it is necessary to avoid the transmission direction of the UL sensing signal conflicting with the symbol type of the corresponding time slot resource. Therefore, the UE partially transmits the UL sensing signal on the UL symbol and / or F symbol.
[0307] In some embodiments, step S2102 above, the first action includes the second action, including:
[0308] Based on the first information, the UE determines that the UE meets the first condition and processes the UL sensing signal based on the second behavior.
[0309] For example, the UE determines the time-frequency resource information of the UL sensing signal and / or the symbol category information of each symbol in the first symbol set where the UL sensing signal is located based on the first information, and then determines whether the UE meets the first condition based on the first information. If the UE meets the first condition, the UL sensing signal is processed based on the second action.
[0310] The first condition includes at least one of the following:
[0311] A subset of the symbols containing the UL sensing signals is indicated as DL symbols by the first DCI;
[0312] A subset of the symbols containing the UL sensing signals is indicated by the first DCI as either a DL symbol or an F symbol;
[0313] A subset of the symbols containing the UL sensing signal is indicated by the second DCI as receiving the DL signal;
[0314] The symbol for the UL sensing signal is F. The terminal did not detect the first DCI, and the terminal did not configure the UL enable configuration parameters.
[0315] The symbol for the UL sensing signal is F. The terminal did not detect the first DCI, and the terminal is configured with UL enable configuration parameters.
[0316] For example, in this embodiment, the first information configured by the network device includes a first DCI and / or a second DCI. The first DCI is DCI 2-0 in the above embodiment, and the definition and function of DCI 2-0 are the same as in the above embodiment, so they will not be repeated here. The second DCI is any other DCI configured by the network device besides DCI 2-0. The first information is used to indicate the symbol category corresponding to the subset of symbols where the UL sensing signal is located and / or whether the subset of symbols where the UL sensing signal is located is used to receive DL signals. The UE determines whether the first condition is met based on the first information. If the UE currently meets the first condition, it uses the second behavior to process the UL sensing signal; if the UE currently does not meet the second condition, the UE does not use the second behavior to process the UL sensing signal, and determines whether the UE meets other criteria based on the first information.
[0317] For example, in this embodiment, the first information includes symbol category information of symbols in the first symbol set, which may be DCI signaling. In some communication scenarios, when a network device dynamically indicates the symbol type of the first symbol set based on the first information, it may cause a conflict between the current symbol type of a subset of the first symbol set (i.e., some or all symbols in the first symbol set) and the subset of symbols where the UL sensing signal is located. Therefore, it is necessary to determine the processing method of the UL sensing signal in the terminal based on the configuration. In some communication scenarios, when a network device dynamically indicates whether a subset of symbols where the UL sensing signal is located is used to receive DL signals based on the first information, it may cause a conflict in the transmission direction between the transmission of the UL sensing signal and the reception of the DL signal on the subset of the first symbol set. In this embodiment, based on the above-mentioned situation where the network device dynamically configures the symbol type of the first symbol set through DCI signaling and the situation where DCI signaling indicates that a subset of the first symbol set receives DL signals, a first condition is set, and a second action that satisfies the first condition processes the UL sensing signal. The first condition may include at least one of the following:
[0318] If the UE determines a subset of the symbols containing the UL sensing signal based on the first information, and the first DCI indicates it as a DL symbol, and determines that the subset of the symbols containing the UL sensing signal in the current first symbol set conflicts with the symbol format indicated by the dynamic signaling DCI, that is, the first condition is met, the second behavior is used to process the UL sensing signal.
[0319] If the UE determines a subset of the symbols containing the UL sensing signal based on the first information, and the first DCI indicates it as a DL symbol or an F symbol, and determines that there is a partial conflict between the subset of the symbols containing the UL sensing signal in the current first symbol set and the symbol format indicated by the dynamic signaling DCI, that is, the UE meets the first condition and uses the second behavior to process the UL sensing signal.
[0320] If a subset of the symbols containing the UL sensing signal is indicated by the second DCI to receive the DL signal, and a subset of the first symbol set is determined as a transmission resource for receiving the DL signal, the transmission of the UL sensing signal on the first symbol set conflicts with the reception of the DL signal in the transmission direction. That is, the UE currently meets the first condition and uses the second behavior to process the UL sensing signal.
[0321] If the symbol of the UL sensing signal is an F symbol, the UE does not detect the first DCI, that is, the current first symbol set is configured as an F symbol, but the UE does not receive further indication information sent by the network device indicating the symbol type on the F symbol, and the terminal does not configure the UL enable configuration parameters. The UE cannot determine whether there is a conflict between the transmission direction of the UL sensing signal and the symbol format of the first symbol set. That is, the UE determines that the first condition is met and uses the second behavior to process the UL sensing signal.
[0322] If the symbol containing the UL sensing signal is an F symbol, and the UE has not detected the first DCI, meaning the current first symbol set is configured as F symbols, and the terminal has UL enable configuration parameters, but the UE has not received further indication information from the network device indicating the transmission direction of the signal on the F symbol, the UE cannot determine whether there is a conflict between the transmission direction of the UL sensing signal and the symbol format of the first symbol set. In other words, the UE determines that the first condition is met and uses the second action to process the UL sensing signal. The UL enable configuration parameters (enableConfigured-UL) are configuration parameters related to UL data transmission. UL configuration involves the configuration of the BWP (Band Width Part), and different UL enable configuration parameters can adapt to different service requirements. In this embodiment, if the UE determines that the symbol containing the UL sensing signal is an F symbol based on the first information, and the UE has not detected the first DCI, it can determine that the UE meets the first condition based on the UL enable configuration parameters configured or not configured in the UE.
[0323] In some embodiments, the first action includes a second action, wherein when the UE satisfies the first condition, it determines to process the UL sensing signal using the second action, wherein the second action includes at least one of the following:
[0324] The UE determines that the terminal does not support partial cancellation capability, and the symbol where the UL sensing signal is located overlaps with the first time domain resource. The UE then sends the UL sensing signal, wherein the first time domain resource is the time domain resource within the first time domain interval after the last symbol of the time domain resource set, and the time domain resource set is the time-frequency resource set where the first downlink control information DCI and / or the second DCI are located.
[0325] The UE determines that it does not support partial cancellation capability, and the symbol of the UL sensing signal does not overlap with the first time domain resource, so it cancels the transmission of the UL sensing signal;
[0326] The UE partially transmits UL sensing signals on the second symbol set and cancels the transmission of UL sensing signals on the third symbol set. The second symbol set is the set of symbols in which the UL sensing signals overlap with the first time domain resources, and the third symbol set is the set of symbols in the UL sensing signals other than the second symbol set.
[0327] The UE determines that it supports partial cancellation capability, partially transmits UL sensing signals on the second symbol set, and cancels the transmission of UL sensing signals on the third symbol set. The second symbol set is the symbol set in which the symbol containing the UL sensing signal overlaps with the first time domain resource, and the third symbol set is the symbol set in the symbol containing the UL sensing signal other than the second symbol set.
[0328] The UE partially transmits UL sensing signals on the second symbol set and cancels the transmission of UL sensing signals on the fourth symbol set. The fourth symbol set is the set of symbols in the fifth symbol set other than the second symbol set. The fifth symbol set is the symbol set where the UL sensing signals are located. The first DCI indicates the set of DL symbols and / or F symbols, and / or the fifth symbol set is the symbol set where the UL sensing signals are located. The second DCI indicates the set of symbols for receiving DL signals.
[0329] The UE determines that it supports partial cancellation capability, partially transmits UL sensing signals on the second symbol set, and cancels the transmission of UL sensing signals on the fourth symbol set. The fourth symbol set is the set of symbols in the fifth symbol set other than the second symbol set. The fifth symbol set is the set of symbols in the symbol set where the UL sensing signals are located. The first DCI indicates the set of DL symbols and / or F symbols, and / or the fifth symbol set is the set of symbols in the symbol set where the UL sensing signals are located. The second DCI indicates the set of symbols for receiving DL signals.
[0330] The UE partially transmits UL sensing signals on the sixth symbol set and cancels the transmission of UL sensing signals on the fourth symbol set. The sixth symbol set is the symbol set that overlaps with the second and fifth symbol sets.
[0331] The UE determines that the terminal supports partial cancellation capability, partially transmits UL sensing signals on the sixth symbol set, and cancels the transmission of UL sensing signals on the fourth symbol set. The sixth symbol set is the symbol set that overlaps with the second and fifth symbol sets.
[0332] The UE sends a UL sensing signal.
[0333] For example, Figure 2B is a schematic diagram of multiple symbol sets in the time domain according to an embodiment of the present disclosure. As shown in Figure 2B, the positions of the relevant symbol sets and time domain resources in the second row described above are explained in the time domain. In this embodiment: the first time domain resource is the time domain resource within a first time domain interval after the last symbol of the CORESET where the DCI is located. The first time domain interval is a set time period for the UE to prepare the UL sensing signal. The set time period is determined based on the UE's processing capability of the UL sensing signal. The starting time of the first time domain interval is the time point corresponding to the last symbol of the CORESET where the DCI is located, and the time point after the set time period after that time point is the end time point of the first time domain interval. For example, the first time-domain interval is TProc-2, and the time-domain resources within TProc-2 after the last symbol of the CORESET where the DCI is located are the first time-domain resources, that is, the duration of the first time-domain resources is equal to the duration of the first time-domain interval; the first symbol set is the symbol set where the UL sensing signal is located; the second symbol set is the intersection of the first symbol set and the first time-domain resources; the third symbol set is the symbol set after removing the second symbol set from the first symbol set; the fourth symbol set is the remaining symbols after removing the sixth symbol set from the fifth symbol set; the fifth symbol set is the symbol set in the first symbol set where the first DCI indicates DL or F, or the second DCI indicates receiving DL signals; the sixth symbol set is the intersection of the second symbol set and the fifth symbol set; the seventh symbol set is the symbol set in the first symbol set after removing the fifth symbol set; the eighth symbol set is the symbol set in the seventh symbol set that indicates UL symbols and / or F symbols.
[0334] When the UE determines that the first condition is met based on the first information, it processes the UL sensing signal based on the second action. The second action includes at least one of the following:
[0335] (1) When the UE does not support partial cancellation and the symbol containing the UL sensing signal overlaps with the first time domain resource, the UL sensing signal is sent. In this embodiment, when the UE does not support partial cancellation and the first time domain interval overlaps with the first symbol set, it is determined that the UE has started preparing the UL sensing signal within the set time domain interval. Since the UE does not support partial cancellation, after the UL sensing signal preparation has started, the UE cannot cancel the transmission of the UL signal. Therefore, in order to avoid power loss and action redundancy in the UE, the UE sends the UL sensing signal to the network device.
[0336] The first time-domain resource refers to the time-domain resources within the first time-domain interval following the last symbol of the time-domain resource set. The time-domain resource set is the time-domain resource set containing the first DCI and / or the second DCI. The symbol set corresponding to the symbol containing the UL sensing signal is the first symbol set in the above embodiment. Both the first symbol set and the first time-domain resource are time-frequency resources. In this embodiment, it is determined whether there is an overlap in the time-domain range of each resource, thereby determining whether there is an overlap between the first symbol set and the first time-domain resource. The first time-domain resource is the time-domain resource within the first time-domain interval following the last symbol of the first DCI and / or the second DCI. The first time-domain resource is usually the time-frequency resource that the UE is preparing to send the UL sensing signal. The UE does not support partial cancellation capability. If the first symbol set and the first time-domain resource overlap, the UE sends the UL sensing signal.
[0337] (2) If the UE does not support partial cancellation capability, and there is no time domain overlap between the first symbol set and the first time domain resource, the UE cancels the transmission of the UL sensing signal. That is, when the UE meets the first condition, there is a symbol conflict or transmission direction conflict on the corresponding first symbol set, and within the set time domain interval, the UE has not started preparing for the UL sensing signal, and canceling the transmission of the UL sensing signal will not cause redundancy to the UE, then the transmission of the UL sensing signal is canceled.
[0338] (3) The UE supports partial cancellation capability and / or does not limit whether the UE supports partial cancellation capability, and the first symbol set overlaps with the first time domain resource. The UE does not expect to cancel the transmission of UL sensing signals in the overlapping part, and cancel the transmission of UL sensing signals on other time-frequency resources. That is, the UE transmits UL sensing signals on some symbol resources and cancels the transmission of UL sensing signals on some symbol resources. For example, the UE partially transmits UL sensing signals on the second symbol set and cancels the transmission of UL sensing signals on the third symbol set, wherein the second symbol set is the symbol set that overlaps with the first symbol set and the first time domain resource, and the third symbol set is the symbol set in the first symbol set other than the second symbol set.
[0339] (4) When the UE supports partial cancellation capability and / or does not limit whether the UE supports partial cancellation capability, and the first symbol set overlaps with the first time domain resource, the UE does not expect to cancel the transmission of UL sensing signals in the overlapping part (i.e., not cancel the transmission of UL sensing signals on the second symbol set), and cancels the transmission of UL sensing signals on the remaining symbols. Based on the above logic, there is no limitation on whether the UE supports partial cancellation capability. When the UE has started preparing UL sensing signals within the first time domain interval, it partially transmits UL sensing signals on the second symbol set and cancels the transmission of UL sensing signals on the remaining symbols. For example, if the remaining symbols are the symbol set in the first symbol set other than the second symbol set, that is, the remaining symbols are the third symbol set, the UE partially transmits UL sensing signals on the second symbol set and cancels the transmission of UL sensing signals on the third symbol set. The remaining symbols can also be a fourth symbol set determined according to the DCI indication, wherein the fourth symbol set is the set of symbols in the fifth symbol set other than the second symbol set, the fifth symbol set is the set of symbols in the first symbol set whose first DCI indication is DL symbols and / or F symbols, or the fifth symbol set is the set of symbols in the first symbol set whose second DCI indication is to receive DL signals. The UE partially transmits UL sensing signals on the second symbol set and cancels the transmission of UL sensing signals on the fourth symbol set.
[0340] (5) When the UE supports partial cancellation capability and / or does not limit whether the UE supports partial cancellation capability, and the first symbol set overlaps with the first time domain resource, the UL sensing signal is partially transmitted on the sixth symbol set, and the transmission of the UL sensing signal is cancelled on the fourth symbol set, wherein the sixth symbol set is a symbol set that overlaps with the second symbol set and the fifth symbol set. For example, the UE can successfully receive DCI signaling, the fifth symbol set is a set of symbols in the first symbol set whose first DCI signaling indicates DL symbols and / or F symbols, or the fifth symbol set is a set of symbols in the first symbol set whose second DCI indicates receiving DL signals. In this case, the symbol type or signal transmission direction of the fifth symbol set conflicts with the transmission direction of the UL sensing signal. If the second symbol set overlaps with the fifth symbol set, the overlapping symbol set is the sixth symbol set, that is, the UE does not expect to cancel the transmission of the UL sensing signal on the sixth symbol set. Therefore, the UE partially transmits the UL sensing signal on the sixth symbol set and cancels the transmission of the UL sensing signal on the fourth symbol set. For example, if the eighth symbol set is a symbol set indicated by the first DCI signaling in the first symbol set as a UL symbol, or a symbol set indicated by the second DCI as a UL signal transmission set, and there is no conflict between the symbol category or signal transmission direction of the eighth symbol set and the symbol category or signal transmission direction of the UL sensing signal, then the UE determines to partially transmit the UL sensing signal on the eighth symbol set.
[0341] (6) When the UE determines that the first condition is met based on the first information, it sends a UL sensing signal. This should be understood as the UE determining that the UL sensing signal is urgent and / or important based on the current network environment. Therefore, even if the UE meets the above first condition, and there is a conflict between the UL sensing signal and the symbol type or transmission direction, the UE will still send the UL sensing signal to the network device to ensure the stable transmission of the sensing signal in the communication system. In addition, when the symbol containing the UL sensing signal is an F symbol, the terminal has not detected the first DCI, and the terminal is configured with UL enable configuration parameters, the UE may default to the F symbol being able to perform UL transmission, and therefore send a UL sensing signal.
[0342] For example, (1) if the time interval between the last symbol of the CORESET (Control Resource Set) where the DCI is located and the first symbol of the UL sensing signal in the first symbol set is less than TProc-2, and the UE does not support partial cancellation capability, then the UE continues to send the UL sensing signal;
[0343] (2) The time interval between the last symbol of the CORESET where the DCI is located and the first symbol of the UL sensing signal in the first symbol set is less than TProc-2. The symbol #1 of the first symbol set is within TProc-2. If the UE supports partial cancellation capability, then the UE sends the UL signal on symbol #1 and cancels the sending of the UL sensing signal in the remaining symbols #2, #3, #4, and #5 of the first symbol set.
[0344] (3) If the time interval between the last symbol of the CORESET corresponding to the DCI and the first symbol of the UL sensing signal in the first symbol set is less than TProc-2, and symbol #1 of the first symbol set is within TProc-2, and the UE supports partial cancellation capability, then the UE transmits the UL signal on symbol #1. If DCI 2-0 indicates DL symbols and / or F symbols, and the fifth symbol set includes 1, #2, and #3, then the transmission of UL sensing signals on the remaining symbols #2 and #3 in the fifth symbol set is cancelled, and UL sensing signals are transmitted on other symbols #4 and #5.
[0345] In some embodiments, the first time-domain interval is the preparation time for the UL sensing signal, which is determined based on the processing capability of the UE.
[0346] For example, in this embodiment, the first time domain interval can be set to TProc-2, which is the preparation time of the UL sensing signal determined by the UE based on the current processing capability. Based on different UE processing capabilities, the time for the UE to prepare the UL sensing signal after responding to the first DCI and / or the second DCI is different. If the UE supports partial cancellation capability, the UE does not expect to cancel the transmission of the corresponding UL sensing signal within the preparation time.
[0347] In some embodiments, the fifth set of symbols includes at least one of the following:
[0348] The set of symbols in which the UL sensing signal is located, indicated by the first DCI as a DL symbol;
[0349] The set of symbols in which the UL sensing signal is located, indicated by the first DCI as either DL symbols or F symbols;
[0350] The symbol containing the UL sensing signal is the set of symbols that receive the DL signal, as indicated by the second DCI.
[0351] For example, in this embodiment, the symbol set containing the UL sensing signal is the first symbol set. The fifth symbol set in the second row mentioned above is: the symbol set in the first symbol set that is indicated by the first DCI and / or the second DCI signaling as not suitable for transmitting UL sensing signals. For example, the symbol set in the first symbol set that the network device indicates as DL symbols by the first DCI; the symbol set in the first symbol set that the network device indicates as a combination of DL symbols and / or F symbols by the first DCI; the symbol set in the first symbol set that the network device indicates as receiving DL signals by the second DCI.
[0352] In some embodiments, the second behavior described above further includes:
[0353] The UE transmits UL sensing signals on the seventh symbol set, which is the set of symbols other than the fifth symbol set among the symbols where the UL sensing signals are located.
[0354] In some embodiments, the second behavior described above further includes:
[0355] The UE transmits UL sensing signals on the eighth symbol set, which consists of UL and / or F symbols from the seventh symbol set.
[0356] In some embodiments, if the UE determines that the transmission level of the UL sensing signal is high in the current network environment and the UE needs to use multiple time-frequency resources to send the sensing signal to the network device, then the UL sensing signal is sent in the seventh symbol set based on the above embodiments, wherein the seventh symbol set is the symbol set in the first symbol set other than the fifth symbol set.
[0357] In some embodiments, the first action includes a third action, and step S2102 above includes:
[0358] Based on the first information, the UE determines that the symbol containing the UL sensing signal is configured and / or indicated to receive the DL signal, and processes the UL sensing signal based on the third action, which includes at least one of the following:
[0359] UE sends UL sensing signal;
[0360] UE cancels sending UL sensing signal;
[0361] The UE determines that the DL signal is a sensing signal and cancels the transmission of the UL sensing signal;
[0362] The UE determines that the DL signal is not a sensing signal and sends a UL sensing signal.
[0363] If the UE determines that the DL signal is a sensing signal and the terminal's sensing mode is not a single-site sensing mode and / or a multi-site sensing mode, it cancels the transmission of the UL sensing signal.
[0364] The UE determines that the DL signal is a sensing signal and that the terminal's sensing mode is single-site sensing mode and / or multi-site sensing mode, and then sends the UL sensing signal.
[0365] For example, if the UE determines, based on the first information, that the first symbol set is configured by the network device to receive DL signals, i.e., the first symbol set is used to carry downlink signals, and there is a conflict between the transmission direction of the UL sensing signal on the UE side and the direction of the downlink signal, then the UE uses a third action to process the UL sensing signal, wherein the third action includes at least one of the following:
[0366] (1) The UE still sends the UL sensing signal based on the first symbol set. It should be understood that the transmission priority of the UL sensing signal on the UE side is higher at this time. Even if the network device is configured to use the first symbol set to receive DL signals, the UE still sends the UL sensing signal to the network device based on this priority.
[0367] (2) The UE cancels the transmission of the UL sensing signal. When the UE determines that there is a conflict between the sensing signal and the DL signal, it cancels the transmission of the UL sensing signal.
[0368] (3) When the UE determines that the DL signal is a sensing signal, both signals are sensing signals and have the same priority. The UE cancels the transmission of the UL sensing signal. Optionally, the UE cancels the reception of the DL sensing signal.
[0369] (4) When the UE determines that the DL signal is not a sensing signal, it sends the UL sensing signal to the network device based on the transmission priority of the UL sensing signal in the UE.
[0370] (5) When the UE determines that the DL signal is a sensing signal and the UE’s current sensing mode is not a single-site and / or multi-site sensing mode, the UL sensing signal is cancelled.
[0371] (6) When the UE determines that the DL signal is a sensing signal and the current sensing mode of the UE is single-site and / or multi-site sensing mode, the UL sensing signal is sent.
[0372] In some embodiments, the sensing signal is a sensing signal that is configured at a higher level or dynamically indicated.
[0373] In some embodiments, the symbol category indicated in the first information is a symbol category configured or dynamically indicated by a higher layer, or the symbol category is a symbol category not configured by a higher layer.
[0374] In some embodiments, the DL signal that conflicts with the UL sensing signal is a DL signal that is configured at a higher level or dynamically indicated.
[0375] In the above manner, the terminal receives first information sent by the network device. This first information includes symbol category information for each symbol in the first symbol set and / or time-frequency resource information for the sensed signal, and / or time-frequency resource information for other signals. Based on this first information, the UL sensed signal is processed according to the first action. Thus, based on the first information sent by the network device, the UE processes the UL sensed signal according to the first action, enabling the UE to process the UL sensed signal under various conflict conditions, ensuring the stability of the sensed service in the communication system and improving communication performance.
[0376] Figure 2C is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2C, the embodiments of the present disclosure relate to a communication method, which includes:
[0377] In step S2201, network device 102 sends first information to terminal 101.
[0378] The optional implementation of step S2201 can be found in the optional implementation of step S2101 in Figure 2A, and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.
[0379] In step S2202, terminal 101 processes the DL sensing signal based on the first information and the first behavior.
[0380] For example, in this embodiment, conflict handling criteria are configured. Based on the first information UE, different conflict situations are determined, and then different methods are used to process the sensing signal based on the different conflict situations. The processing of the sensing signal includes receiving the sensing signal, prohibiting the reception of the sensing signal, and partially receiving the sensing signal.
[0381] Similar to the reference configuration in Tables 1, 2 and 3 of the above embodiments, the UE is configured with multiple mapping relationships between multiple situations and multiple first actions. The UE determines the situation information corresponding to the current sensing signal in the configuration relationship based on the first information, and then determines the target first action corresponding to the situation information based on the mapping relationship, thereby processing the sensing signal based on the target first action.
[0382] In some embodiments, the sensing signal includes a DL sensing signal, in which case the UE needs to receive the DL sensing signal based on the transmission resources of DL symbols and / or F symbols. The corresponding first action in the UE based on the DL sensing signal includes at least one of the following:
[0383] UE cancels receiving DL sensing signals;
[0384] UE receives DL sensing signals;
[0385] The UE partially receives DL sensing signals on DL symbols and / or F symbols.
[0386] For example, in this embodiment, the UE determines, based on first information, to process the sensing signal according to a first action. The symbol types of the symbols in the first set indicated by the first information are different, and / or the time-frequency resources of the sensing signal corresponding to the first information are different, leading to different processing methods for the sensing signal by the UE. The first action includes: the UE canceling the reception of the DL sensing signal, the UE receiving the DL sensing signal, and the UE partially receiving the DL sensing signal on DL symbols and / or F symbols. For instance, if the UE determines, based on the first information, that all symbols in the first symbol set indicated by the network device are DL symbols, the UE can receive the sensing signal based on the first information; if the UE determines, based on the first information, that the first symbol set indicated by the network device includes at least one UL symbol or F symbol, and the UE determines that the symbol type of the first symbol set conflicts with the DL sensing signal, the UE can cancel the reception of the sensing signal based on the first information; if the UE determines that the symbol types of the first symbol set include DL symbols and F symbols, the UE determines to partially receive the DL sensing signal on the non-conflicting symbols, that is, the UE determines, based on the first information, to partially receive the DL sensing signal on DL symbols and / or F symbols.
[0387] In some embodiments, step S2202 above includes:
[0388] Based on the first information, the UE determines that the symbol category of the DL sensing signal is a DL symbol and receives the DL sensing symbol; or,
[0389] Based on the first information, the UE determines that the symbol category of the DL sensing signal includes at least one UL symbol or F symbol, and then cancels the reception of the DL sensing signal.
[0390] For example, based on different first information received by the network device, the UE applies and pre-configures accurately, and processes DL sensing signals in different ways. The UE's configured processing criteria for DL sensing signals include:
[0391] When the UE determines that the symbol category of the DL sensing signal is DL symbol based on the first information, the UE determines that the reception of the current DL sensing signal matches the symbol category of the current first symbol set. That is, the symbol category of the first symbol set is DL receiving resource, and there is no conflict between the reception of the DL sensing signal and the symbol category. At this time, the UE determines to receive the DL sensing signal.
[0392] When the UE determines, based on the first information, that the symbol category of the DL sensing signal includes at least one UL symbol or F symbol, the UE considers the time slot resources configured by the current network device to be incorrect and cancels the reception of the DL sensing signal. Alternatively, the UE may consider it an error case, meaning the UE does not expect this situation to occur. For example, the UE may not expect this situation to occur by considering it an error case and canceling the reception of the DL sensing signal, or the UE may report the current error case to the network device, which will then reconfigure the time slot resources used for transmitting the DL sensing signal based on this error feedback. In this embodiment, the subsequent actions of the UE in considering it an error case are not limited; the UE can set them based on the current network environment and communication requirements.
[0393] It should be noted that in this embodiment, the condition for the UE to receive the DL sensing signal is that all symbols of the sensing signal are DL symbols. If the symbol category corresponding to the sensing signal includes at least one other symbol category (e.g., UL symbol and / or F symbol), the reception of the DL sensing signal is cancelled. This can be understood as the urgency of receiving the DL sensing signal in the UE being low at this time. If the direction of receiving the DL sensing signal does not match the symbol of the sensing signal in the UE, the UE does not want this to happen and will cancel the reception of the DL sensing signal.
[0394] In some embodiments, step S2202 above includes:
[0395] The UE determines, based on the first information, that the symbol category of the DL sensing signal is DL symbol and / or F symbol, and receives the DL sensing signal; or, the UE determines, based on the first information, that the symbol category of the DL sensing signal includes at least one UL symbol, and cancels receiving the DL sensing signal.
[0396] For example, the UE determines the symbol category of the DL sensing signal based on the first information. If there is at least one UL symbol in the symbol category of the DL sensing signal, the UE determines that there is a conflict between the current DL sensing signal and the symbol type, and cancels the reception of the DL sensing signal accordingly. Otherwise, the UE can receive the DL sensing signal when it determines that the symbol category of the DL sensing signal is a DL symbol and / or an F symbol based on the first information. For example, the UE can receive the DL sensing signal on DL symbols and / or F symbols.
[0397] It should be noted that the reception level of the DL sensing signal configured in the UE in this embodiment is higher than that in the above embodiments. If the time slot resource type corresponding to the DL sensing signal in the symbol set indicated by the first information includes at least one UL symbol, the UE does not expect this to happen, or cancels the reception of the DL sensing signal; if the time slot resource type corresponding to the DL sensing signal in the symbol set indicated by the first information includes DL symbols and / or F symbols, the UE receives the DL sensing signal.
[0398] In some embodiments, step S2202 above includes:
[0399] Based on the first information, the UE determines that the symbol category of the DL sensing signal includes DL symbol, F symbol and UL symbol, and receives the DL sensing signal.
[0400] For example, in this embodiment, the UE receives the DL sensing signal when it determines that the symbol category of the DL sensing signal includes DL symbols, F symbols, and UL symbols. That is, in this embodiment, the transmission level of the DL sensing signal is high, and the UE's reception of the DL sensing signal is urgent in the current network environment. Therefore, even when the UE determines, based on the first information, that the symbol category of the DL sensing signal includes DL symbols, F symbols, and UL symbols, the UE still receives the DL sensing signal.
[0401] In some embodiments, step S2202 above includes:
[0402] Based on the first information, the UE determines that the symbol category of the DL sensing signal includes DL symbol, F symbol and UL symbol, and partially receives the DL sensing signal on the DL symbol and / or F symbol.
[0403] For example, when the UE determines that the symbol category of the DL sensing signal includes DL symbols, F symbols and UL symbols based on the first information, in order to ensure the reception of the DL sensing signal in the UE, it is necessary to avoid the transmission direction of the DL sensing signal conflicting with the symbol type of the corresponding time slot resource. Therefore, the UE partially receives the DL sensing signal on DL symbols and / or F symbols.
[0404] In some embodiments, the first action includes a fourth action, and step S2202 above includes:
[0405] Based on the first information, the UE determines that the second condition is met and processes the DL sensing signal based on the fourth line.
[0406] For example, the second condition is that the first symbol set is configured as F symbols, and the UE does not detect the first DCI. When the UE determines that the second condition is met, it processes the DL sensing signal based on the fourth line, which includes receiving the DL sensing signal or canceling the reception of the DL sensing signal. It should be noted that the symbol set corresponding to the DL sensing signal is configured as F symbols, and the UE does not detect the first DCI. The first DCI is used to dynamically indicate the symbol type of the first symbol set. Therefore, the UE can freely determine based on the current network environment, or determine whether to receive or cancel the reception of the DL sensing signal through other condition parameters.
[0407] In some embodiments, the first action includes the fifth action, and step S2202 above includes:
[0408] Based on the first information, the UE determines that the symbol containing the DL sensing signal is configured and / or indicated to transmit a UL signal, and processes the sensing signal based on the fifth line, which includes at least one of the following:
[0409] UE receives DL sensing signals;
[0410] UE cancels receiving DL sensing signals;
[0411] The UE determines that the UL signal is a sensing signal and cancels the reception of the DL sensing signal;
[0412] The UE determines that the UL signal is not a sensing signal and receives the DL sensing signal;
[0413] If the UE determines that the UL signal is a sensing signal and the terminal's sensing mode is not a single-site sensing mode and / or a multi-site sensing mode, it will cancel receiving the DL sensing signal.
[0414] The UE determines that the UL signal is not a sensing signal and that the terminal's sensing mode is single-site sensing mode and / or multi-site sensing mode, and then receives the DL sensing signal.
[0415] For example, in this embodiment, when the network device configures the first symbol set containing the DL sensing signal to send a UL signal based on the first information through higher-layer configuration or dynamic signaling, if the transmission direction of the DL sensing signal on the UE side conflicts with the UL signal, the UE uses the fifth action to process the DL sensing signal, wherein the fifth action includes at least one of the following:
[0416] (1) The UE still receives the DL sensing signal based on the first symbol set. It should be understood that the transmission priority of the DL sensing signal on the UE side is higher at this time. Even if the network device configures the first symbol set to send the UL signal, the UE still receives the DL sensing signal sent by the network device based on this priority.
[0417] (2) UE cancels receiving DL sensing signal. When the UE determines that there is a conflict between the sensing signal and the transmission resources, it cancels receiving the DL sensing signal.
[0418] (3) When the UE determines that the UL signal is a sensing signal, it takes the first information indicated in the network device as the standard, determines that the current sensing signal transmission direction is to send the UL sensing signal, and correspondingly cancels the reception of the DL sensing signal in the UE.
[0419] (4) When the UE determines that the UL signal is not a sensing signal, it receives the DL sensing signal sent by the network device based on the transmission priority of the DL sensing signal in the UE.
[0420] (5) When the UE determines that the UL signal is a sensing signal and the UE's current sensing mode is not a single-site sensing mode and / or a multi-site sensing mode, the UE cancels the reception of the DL sensing signal.
[0421] (6) When the UE determines that the UL signal is a sensing signal and the UE's current sensing mode is single-site sensing mode and / or multi-site sensing mode, the UE cancels the reception of the DL sensing signal.
[0422] In some embodiments, the transmitter of the DL sensing signal is UE#A. Based on the second line in step S2102, it is determined that the symbol where UE#A transmits the DL sensing signal is the ninth symbol set. UE#B receives the DL sensing signal in the ninth symbol set. UE#B and UE#A may be the same or different.
[0423] In some embodiments, the sensing signal is a sensing signal that is configured at a higher level or dynamically indicated.
[0424] In some embodiments, the symbol category indicated in the first information is a symbol category configured or dynamically indicated by a higher layer, or the symbol category is a symbol category not configured by a higher layer.
[0425] In the above manner, the terminal receives first information sent by the network device. This first information includes symbol category information for each symbol in the first symbol set and / or time-frequency resource information of the sensing signal. Based on this first information, the DL sensing signal is processed according to the first action. Thus, based on the first information sent by the network device, the UE processes the DL sensing signal according to the first action, enabling the UE to process the DL sensing signal under various conflict conditions, ensuring the stability of the sensing service in the communication system and improving communication performance.

[0536] (6.6) The UE does not support partial cancellation capability;
[0537] For example, if the interval between the last symbol of the CORESET where the DCI is located and the first symbol of the sensing signal does not exceed TProc-2, the UE does not expect to cancel the transmission of the sensing signal; if the interval between the last symbol of the CORESET where the DCI is located and the first symbol of the symbol set where the sensing signal is located exceeds TProc-2, the UE cancels the transmission of the sensing signal.
[0538] For example, if the second symbol set is not empty, send a UL sensing signal; if the second symbol set is empty, cancel sending the UL sensing signal.
[0539] (6.7.1) The UE does not expect to cancel the transmission of sensing signals within TProc-2 after the last symbol of the CORESET where the DCI is located, and to cancel the transmission of sensing signals on the remaining symbols in the symbol where the sensing signal is located;
[0540] For example, the UE does not expect to cancel the transmission of UL sensing signals on the second symbol set, and the UE cancels the transmission of UL sensing signals on the third symbol set;
[0541] For example, whether the UE supports partial cancellation capability in this embodiment is not a condition limitation in the above processing method (6.7.1);
[0542] (6.7.2) If the UE does not expect to cancel the transmission of sensing signals within TProc-2 after the last symbol of the CORESET where the DCI is located, the UE cancels the transmission of sensing signals on the remaining symbols in the fourth symbol set;
[0543] For example, the UE does not expect to cancel the transmission of UL sensing signals on the sixth symbol set, and the UE cancels the transmission of UL sensing signals on the fourth symbol set;
[0544] Optionally, the UE transmits UL sensing signals on the seventh symbol set, which is the first symbol set excluding the fifth symbol set;

[0546] (6.8) The UE sends a sensing signal;
[0547] In some embodiments, the first set of symbols in the second action is at least one of the following:
[0548] In the symbols present in the sensing signal, DCI 2-0 indicates the DL symbol;
[0549] In the symbols present in the sensing signal, DCI 2-0 indicates either a DL symbol or an F symbol;
[0550] In the symbols of the sensing signal, DCI indicates the symbol for receiving DL signals;
[0551] In some embodiments, TProc-2 is the sensing signal preparation time determined based on the UE's processing capabilities.
[0552] (7) The symbol containing the sensing signal is configured or dynamically indicated by a higher layer to receive the DL signal, and is processed according to the third action, which includes at least one of the following:
[0553] (7.1) Send sensing signals;
[0554] (7.2) The UE considers this an error case and does not expect the UE to send data under these circumstances;
[0555] (7.3) If the DL signal is a sensing signal, the UE considers it an error case and does not expect this situation to occur; otherwise, it will send a sensing signal.
[0556] (7.4) If the DL signal is a sensing signal and the UE’s current sensing transmission mode is not single-site sensing mode and / or multi-site sensing mode, the UE considers it an error case and does not expect this situation to occur; otherwise, it sends a sensing signal.
[0557] In some embodiments, the sensing signal is a sensing signal indicated by higher-level configuration or dynamic signaling.
[0558] In some embodiments, DL symbols or UL symbols are symbol categories indicating higher-level configuration or dynamic signaling.
[0559] In some embodiments, the F symbol may be a symbol category indicated by higher-level configuration or dynamic signaling, or a symbol category not configured by higher-level configuration.
[0560] For example, this embodiment provides a complete set of methods for determining cancel transmission / partial transmission / transmission of sensing signals in the UE, wherein the sensing signals and symbol categories can be divided into at least one of the following cases:
[0561] (1) The sensing signal is a sensing signal configured or dynamically indicated by a high-level configuration;
[0562] (2) The DL symbol or UL symbol can be a symbol category for high-level configuration or dynamic indication;
[0563] (3) The F symbol can be a symbol category configured or dynamically indicated by the higher level or a symbol category not configured by the higher level;
[0564] The processing methods differ depending on whether the sensing signal is a higher-level configuration or dynamic indication; the processing methods differ when the DL / UL symbol can be a symbol category of a higher-level configuration or dynamic indication; and the processing methods differ when the F symbol can be a symbol category of a higher-level configuration or dynamic indication or a symbol category not configured by the higher level. In this embodiment, the processing method for sensing signals in the UE is determined based on the following Table 4:
[0565] In Table 4 above, in signal A, RRC-U refers to the UL sensing signal configured in the upper floors, and Dynamic-U is the UL sensing signal with dynamic indication.
[0566] For example, based on Table 4 above, if the UE determines that the first condition is met according to the first information, it processes the sensing signal according to the second action, including at least one of the following examples:
[0567] Alt (Example) 0: If the UE does not support partial cancellation capability, and the interval between the last symbol of the CORESET containing the DCI and the first symbol of the UL signal does not exceed TProc-2, the UE does not expect to cancel the transmission of the UL signal. If the UE does not support partial cancellation capability, and the interval between the last symbol of the CORESET containing the DCI and the first symbol of the UL signal exceeds TProc-2, the UE cancels the transmission of the UL signal.
[0568] Here, Alt 0 can be understood as: if the second symbol set is not empty, send the UL sensing signal; if the second symbol set is empty, cancel sending the UL sensing signal.
[0569] Alt 1: The UE does not expect to cancel the UL signal within TProc-2 after the last symbol of the CORESET where the DCI is located; the UE cancels the transmission of the UL signal on the remaining symbols of the sensing signal.
[0570] For example, it is not limited whether the UE supports partial cancellation capability or not. Alt1 can be understood as: the UE does not expect to cancel the UL sensing signal on the second symbol set, and the UE cancels the transmission of the UL sensing signal on the third symbol set;
[0571] Alt 2: The UE does not wish to cancel the UL signal within TProc-2 after the last symbol of the CORESET where the DCI is located, and the UE cancels the transmission of the UL signal on the remaining symbols in the fifth symbol set; wherein the fifth symbol set includes at least one of the following: symbols indicated as DL by DCI 2-0; symbols indicated as DL or F by DCI 2-0; symbols indicated as receiving DL signals by DCI. Optionally, the UE transmits the UL sensing signal on the seventh symbol set, which is the symbols in the first symbol set excluding the fifth symbol set; optionally, the UE transmits the UL sensing signal on the eighth symbol set, which is the UL and / or F symbols in the seventh symbol set. Alt 2 can be understood as the UE not wishing to cancel the transmission of the UL sensing signal on the sixth symbol set, and the UE cancels the transmission of the UL sensing signal on the fourth symbol set.
[0572] Figure 5B is a schematic diagram illustrating the second behavior according to an embodiment of the present disclosure. As shown in Figure 5B, in this embodiment, the UE transmits a sensing signal based on the second behavior. For example, Example 1: When the interval between the last symbol of the DCI and the first symbol of the UL signal is less than TProc-2, the UE does not expect to cancel the transmission of the UL signal and will continue to transmit the UL signal; Example 2: When the interval between the last symbol of the DCI and the first symbol of the UL signal is less than TProc-2, symbol #1 in the symbol set where the UL signal is located is within TProc-2, so the UE transmits the UL signal on symbol #1 and cancels the transmission of the UL signal in the remaining symbols #2, #3, #4, and #5 in the symbol set; Example 3: When the interval between the last symbol of the DCI and the first symbol of the UL signal is less than TProc-2, symbol #1 is within TProc-2, so the UE transmits the UL signal on symbol #1. If the symbol set containing the UL symbol is the first symbol set, the fifth symbol set, indicated by DCI 2-0 as DL or F, includes symbols #1, #2, and #3. Therefore, the transmission of UL signals on symbols #2 and #3 in the fourth symbol set will be cancelled. If the seventh or eighth symbol set contains symbols #4 and #5, then UL signals will be transmitted on symbols #4 and #5.
[0573] In this way, the UE can transmit sensing signals on the same DL / UL / F symbols in single-site and / or multi-site sensing modes, enabling the transmission of sensing signals in more conflict situations, ensuring the stability of sensing services in the communication system, and improving communication performance.
[0574] Figure 5C is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 5C, the present disclosure relates to a communication method, which includes:
[0575] In step S5201, the UE receives first information sent by the network device, the first information including symbol category configuration and / or indication information.
[0576] In step S5202, the UE determines the symbol category of each symbol and / or the time-frequency resources where other signals are located based on the first information;
[0577] In step S5203, the UE processes the DL sensing signal according to the target processing method among multiple processing methods based on the symbol category.
[0578] In some embodiments, the processing of the sensing signal includes at least one of the following: canceling the reception of the sensing signal, partially receiving the sensing signal, and receiving the sensing signal.
[0579] In some embodiments, the multiple processing methods include at least one of the following:
[0580] (1) If all symbols of the sensing signal are DL, the sensing signal is received; otherwise, it is processed according to the fourth line, wherein the fourth line includes at least one of the following:
[0581] Cancel receiving sensing signals;
[0582] The UE considers this an error case, meaning that the UE does not expect this situation to occur.
[0583] (2) If all the symbols of the sensing signal are DL symbols or F symbols, receive the sensing signal; otherwise, process it according to the fourth line.
[0584] (3) When the symbol of the sensing signal is a UL symbol, a DL symbol, or an F symbol, receive the sensing signal;
[0585] (4) When the symbol of the sensing signal is a UL symbol, a DL symbol, or an F symbol, the sensing signal is received on the upper part of the DL symbol.
[0586] (5) When the symbol of the sensing signal is a UL symbol, a DL symbol, or an F symbol, the sensing signal is received on the upper part of the DL symbol and the F symbol.
[0587] (6) The transmitting end of the sensing signal is another terminal. Based on the first information, it is determined that the symbol transmitted by the sensing signal is the ninth symbol set, and the sensing signal is received in the ninth symbol set.
[0588] (7) The UE determines that the second condition is met based on the first information and processes the sensing signal according to the fifth line;
[0589] For example, the second condition is: the symbol where the sensing signal is located is the F symbol, and the UE has not successfully detected DCI 2-0;
[0590] The fifth action includes at least one of the following: receiving a sensing signal, or canceling the receiving of a sensing signal;
[0591] (8) The symbol containing the sensing signal is configured or dynamically indicated by the higher layer to transmit the UL sensing signal, and is processed according to the sixth line, wherein the sixth line includes at least one of the following:
[0592] Receive sensing signals;
[0593] The UE considers this an error case, meaning that the UE does not expect this situation to occur.
[0594] If the UL signal is a sensing signal, the UE considers it an error case, meaning the UE does not expect this situation to occur; otherwise, it will receive the sensing signal.
[0595] If the UL signal is a sensing signal, and the UE's current sensing mode is not single-site sensing mode and / or multi-site sensing mode, the UE considers it an error case, meaning the UE does not expect this situation to occur; otherwise, it sends a sensing signal.
[0596] In some embodiments, the sensing signal is a sensing signal indicated by higher-level configuration or dynamic signaling.
[0597] In some embodiments, the DL symbol or UL symbol is the symbol category indicated by higher-level configuration or dynamic signaling.
[0598] In some embodiments, the F symbol may be a symbol category indicated by higher-level configuration or dynamic signaling, or a symbol category not configured by higher-level configuration.
[0599] In some embodiments, the UE determines whether to cancel receiving / partially receive or receive sensing signals in the following ways. The processing differs depending on whether the sensing signal is a higher-layer configured or dynamically indicated signal; whether the DL / UL symbol is a symbol category configured or dynamically indicated by the higher-layer; and whether the F symbol is a symbol category configured or dynamically indicated by the higher-layer or a symbol category not configured by the higher-layer. For example, based on different situations, the following Table 5 is configured to receive sensing signals / partially receive sensing signals / cancel receiving sensing signals:
[0600] In Table 5 above, in signal A, RRC-D refers to the DL sensing signal configured at higher levels, and Dynamic-D is the DL sensing signal with dynamic indication.
[0601] In this way, the UE can transmit sensing signals on the same DL / UL / F symbols in single-site and / or multi-site sensing modes, enabling the reception of sensing signals in more conflict situations, ensuring the stability of sensing services in the communication system, and improving communication performance.
[0602] Figure 5D is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 5D, the present disclosure relates to a communication method, which includes:

[0605] The first information also includes information such as the location of time and frequency resources for the sensing signal, to determine the time and frequency resources used by the sensing signal.
[0606] In some embodiments, the time-frequency resource location of the sensed signal is determined by high-level configuration and / or DCI indication / MAC CE.
[0607] The first information may also include information such as the location of time and frequency resources for other DL and / or UL signals, to determine the time and frequency resources used by other DL and / or UL signals.
[0608] Step S5302: Determine the sending and / or receiving behavior of the sensing signal based on the first information.

[0610] The above methods enable the transmission / reception of sensing signals in single-station and / or multi-station sensing modes under more collision conditions.
[0611] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.
[0612] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.
[0613] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
