[0209] In each of the disclosed embodiments, unless otherwise specified or in case of logical conflict, the terminology and / or descriptions of the embodiments are consistent and can be referenced by each other. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0210] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the scope of this disclosure.

Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the object being described is "device", then "first device" and "second device" can be the same device or different devices, and their types can be the same or different. Similarly, if the object being described is "information", then "first information" and "second information" can be the same information or different information, and their content can be the same or different.

[0234] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0235] In some embodiments, the core network equipment may be a single device, multiple devices, or a group of devices. The core network may include at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0240] Figure 1B is a schematic diagram illustrating a sensing mode according to an embodiment of the present disclosure. As shown in Figure 1B, the research on ISCA technology includes six sensing modes: TRP-to-TRP bi-static (dual-station), TRP mono-static (single-station), TRP-to-UE bi-static, UE-to-TRP bi-static, UE-to-UE bi-static, and UE mono-static.

[0241] In UE-to-UE bi-static mode, UE B receives sensing signals from UE A. In UE mono-static mode, UE A needs to transmit and receive sensing signals on the same symbol.

[0242] In some embodiments, among the time slots contained in 1024 frames, time slots that meet one of the following conditions are removed, and the remaining time slots are candidate sidelink time slots:

[0243] Condition 1: The time slot contains an SSB;

[0244] Condition 2: At least one symbol in the symbol containing the Sidelink resource is configured as a DL;

[0245] Condition 3: Reserved time slots.

[0246] In some embodiments, the Sidelink slots of the Sidelink resource pool can be selected from the candidate Sidelink slots.

[0247] In some embodiments, a bitmap can be used to select a slot from the candidate Sidelink slots.

[0248] Wherein, the bitmap length is L, and when the value of the kmodL-th bit in the bitmap is 1, slot k in the candidate Sidelink slot belongs to the Sidelink slot.

[0249] In some embodiments, the frequency domain range of the Sidelink resource pool may include at least one of the following:

[0250] Configure sl-NumSubchannel subchannels;

[0251] The starting RB of the first subchannel is sl-StartRB-Subchannel-r16;

[0252] The number of RBs in each subchannel is sl-SubchannelSize-r16;

[0253] The sl-NumSubchannel subchannels constitute the frequency domain range of the Sidelink resource pool.

[0254] In some embodiments, UL symbols are available in Sidelink and a Sidelink resource pool is configured. When this technology is used for sensing, the following issues may arise:

[0255] The DL symbol may also be used for transmitting / receiving Sensing signals;

[0256] Sensing signals may not require a resource pool configuration. Whether to send / receive a Sensing signal is determined based on the symbol type of the Sensing signal and its conflict with other signals.

[0257] The conditions and methods for configuring the resource pool using Sensing signals to determine the time-frequency resources in the resource pool may differ from those used in Sidelink.

[0258] In some embodiments, the protocol defaults / higher-level configurations / dynamically indicates the available time-domain and / or frequency-domain resources for the sensing signal, and the sensing signal is transmitted on the available time-domain and / or frequency-domain resources for the sensing signal, the transmission of the sensing signal including sending and / or receiving the sensing signal.

[0259] In some embodiments, Sensing signals can be sent and / or received via high-level configuration / dynamic indication on all symbols or the first symbol type.

[0260] Different symbol types can be used for the sending and receiving of Sensing signals during Sensing.

[0261] In some embodiments, a Sensing time-frequency resource pool can be configured, in which Sensing signals configured / dynamically indicated by higher layers can be sent and / or received. Specifically, this may include the following steps:

[0262] Conditions for determining candidate time slots for the Sensing time-frequency resource pool;

[0263] A method for selecting time slots for sensing from candidate time slots in the Sensing time-frequency resource pool;

[0264] Determine the frequency domain configuration method in the Sensing time-frequency resource pool.

[0265] Figure 2A is an interactive schematic diagram illustrating a communication method according to an embodiment of the present disclosure. This method can be executed by the aforementioned communication system. As shown in Figure 2A, the method may include:

[0266] Step S2101: The terminal device determines the time domain resources used by the sensing signal based on the first symbol type.

[0267] In some embodiments, symbols of the first symbol type can be used as time-domain resources for sensing signals.

[0268] In some embodiments, the first symbol type may be pre-configured or indicated by the network device.

[0269] In some embodiments, the network device may pre-configure the first symbol type and indicate the first symbol type to the terminal device. For example, the network device may send first information to the terminal device, the first information including the first symbol type.

[0270] In some embodiments, the first symbol type may include at least one of the following: downlink (DL), uplink (UL), flexible (F), non-overlapping subband full duplex (SBFD), partially overlapped SBFD, and shared spectrum full duplex (SSFD).

[0271] In some embodiments, the time-domain and / or frequency-domain resources used by the sensing signal can be used for a first sensing mode.

[0272] In some embodiments, the first sensing mode may include at least one of the following: a single-station sensing mode and a multi-station sensing mode.

[0273] In some embodiments, the first symbol type may be the same as the second symbol type, which may include at least one of the following: DL, UL, F, SSFD.

[0274] For example, if the first symbol type is DL, the DL symbol can be used as a time-domain resource for the sensing signal; if the first symbol type is UL, the UL symbol can be used as a time-domain resource for the sensing signal; if the first symbol type is F, the F symbol can be used as a time-domain resource for the sensing signal; if the first symbol type is SSFD, the SSFD symbol can be used as a time-domain resource for the sensing signal.

[0275] In some embodiments, "the first symbol type is the same as the second symbol type" can be understood as the first symbol type including at least one of the following: DL, UL, F, SSFD, that is, the first symbol type does not include non-overlapping SBFD and partially overlapping SBFD.

[0276] In some embodiments, SSFD symbols can be used simultaneously for DL ​​signal and UL signal transmission on the same frequency domain resources.

[0277] In some embodiments, the first symbol type is a non-overlapping SBFD.

[0278] In some embodiments, the first symbol type is a partially overlapping SBFD.

[0279] Step S2102: The terminal device determines the frequency domain resources used by the sensing signal.

[0280] In some embodiments, if the first symbol type is the same as the second symbol type, the frequency domain resources used by the sensed signal may include at least one of the following: the frequency domain range of the carrier component (CC) and the frequency domain range of the bandwidth part (BWP).

[0281] Figure 2B is a schematic diagram of a resource according to an embodiment of the present disclosure. As shown in Figure 2B, the sensing resource represents the frequency domain resource that the sensing signal can use. For example, when the first symbol type is DL, the frequency domain resource of the sensing signal can be resource #1 (DL#1 in Figure 2B), and when the second symbol type is UL, the frequency domain resource of the sensing signal can be resource #2 (UL#2 in Figure 2B).

[0282] Figure 2C is a schematic diagram of a resource according to an embodiment of the present disclosure. As shown in Figure 2C, when the first symbol type is SSFD, for example, the frequency domain resource of the sensed signal can be resource #1 (SSFD #1 in Figure 2C).

[0283] In some embodiments, if the first symbol type is a non-overlapping SBFD, the frequency domain resources used by the sensed signal may include at least one of the following:

[0284] DL subbands with non-overlapping SBFD symbols;

[0285] UL sub-bands with non-overlapping SBFD symbols;

[0286] The DL subband, UL subband, and first frequency domain spacing of the non-overlapping SBFD symbol, wherein the first frequency domain spacing may be the frequency domain spacing between the DL subband and UL subband on the non-overlapping SBFD symbol.

[0287] In some embodiments, a non-overlapping SBFD symbol is a symbol of type non-overlapping SBFD.

[0288] For example, if the first symbol type is non-overlapping SBFD, the frequency domain resources used by the sensing signal can be the DL subband of the non-overlapping SBFD symbol, the UL subband of the non-overlapping SBFD symbol, or the DL subband, UL subband, and frequency domain spacing between the DL subband and UL subband of the non-overlapping SBFD symbol.

[0289] Figure 2D is a resource schematic diagram according to an embodiment of the present disclosure. As shown in Figure 2D, when the first symbol type is a non-overlapping SBFD, for example, the frequency domain resource of the sensing signal can be a DL subband of a non-overlapping SBFD symbol, i.e., resource #2 in Figure 2D (DL#2 in Figure 2D). In this case, the maximum bandwidth corresponding to the sensing signal is the bandwidth of the two DL subbands on CC or the frequency domain range where the bandwidth of the two DL subbands on CC overlaps with BWP (the overlapping area is not shown in Figure 2D). The frequency domain resource of the sensing signal can also be a UL subband of a non-overlapping SBFD symbol, i.e., resource #1 in Figure 2D (UL#1 in Figure 2D). In this case, the maximum bandwidth corresponding to the sensing signal is the bandwidth of the UL subband or the frequency domain range where the bandwidth of the UL subband on CC overlaps with BWP (the overlapping area is not shown in Figure 2D). The frequency domain resources of the sensing signal can also be the DL subband, UL subband and frequency domain spacing between the DL subband and UL subband with non-overlapping SBFD symbols, i.e., resource #3 in Figure 2D (UL#3 and DL#3 in Figure 2D). In this case, the maximum bandwidth corresponding to the sensing signal is CC or BWP.

[0290] In some embodiments, the non-overlapping SBFD symbol may include a DL subband and a UL subband, and the DL subband and the UL subband do not overlap in the frequency domain.

[0291] In some embodiments, if the first symbol type is partially overlapped SBFD, the frequency domain resources used by the sensed signal may include at least one of the following:

[0292] SSFD subbands with partially overlapping SBFD symbols;

[0293] The SSFD subband, DL subband, and second frequency domain spacing of partially overlapping SBFD symbols, wherein the second frequency domain spacing is the spacing between adjacent SSFD subbands and DL subbands on the partially overlapping SBFD symbols;

[0294] The overlapping SBFD symbols include the SSFD subband, UL subband, and third frequency domain spacing, where the third frequency domain spacing is the spacing between adjacent SSFD subbands and UL subbands on the overlapping SBFD symbols.

[0295] The overlapping SBFD symbols include the SSFD subband, DL subband, UL subband, and a fourth frequency domain interval. The fourth frequency domain interval is the interval between adjacent subbands on the overlapping SBFD symbols. The adjacent subbands may include two adjacent subbands among the SSFD subband, DL subband, and UL subband.

[0296] In some embodiments, a partially overlapping SBFD symbol is a symbol of type partially overlapping SBFD.

[0297] In one implementation, if the first symbol type is partially overlapping SBFD, then the frequency domain resources used by the sensing signal can be the SSFD subband of partially overlapping SBFD symbols.

[0298] In another implementation, if the first symbol type is partially overlapping SBFD, the frequency domain resources used by the sensing signal can be the SSFD subband, DL subband, and the interval between adjacent SSFD subbands and DL subbands of the partially overlapping SBFD symbols.

[0299] In another implementation, if the first symbol type is partially overlapping SBFD, the frequency domain resources used by the sensing signal can be the SSFD subband, UL subband, and the spacing between adjacent SSFD subbands and UL subbands of the partially overlapping SBFD symbols.

[0300] In another implementation, if the first symbol type is partially overlapping SBFD, the frequency domain resources used by the sensing signal can be the SSFD sub-band, DL sub-band, UL sub-band of the partially overlapping SBFD symbol, as well as the intervals between adjacent SSFD sub-bands and DL sub-bands, the intervals between adjacent SSFD sub-bands and UL sub-bands, and the intervals between adjacent DL sub-bands and UL sub-bands.

[0301] In some embodiments, the frequency domain distribution of partially overlapping SBFD symbols includes at least one of the following:

[0302] It includes DL subband and SSFD subband. The DL subband and SSFD subband do not overlap in the frequency domain. The SSFD subband can be used for DL ​​signal and UL signal transmission at the same time.

[0303] It includes UL subband and SSFD subband, and the UL subband and SSFD subband do not overlap in the frequency domain;

[0304] It includes DL subband, UL subband and SSFD subband, and the different types of subbands do not overlap in the frequency domain.

[0305] For example, if a partially overlapping SBFD symbol contains a DL subband and an SSFD subband, the frequency domain resources used by the sensing signal are the SSFD subband, DL subband, and the spacing between adjacent SSFD subbands and DL subbands of the partially overlapping SBFD symbol; if a partially overlapping SBFD symbol contains a UL subband and an SSFD subband, the frequency domain resources used by the sensing signal may be the SSFD subband, UL subband, and the spacing between adjacent SSFD subbands and UL subbands of the partially overlapping SBFD symbol; if a partially overlapping SBFD symbol contains a DL subband, UL subband, and SSFD subband, the frequency domain resources used by the sensing signal may be the SSFD subband, DL subband, UL subband, and the spacing between adjacent SSFD subbands and DL subbands, the spacing between adjacent SSFD subbands and UL subbands, and the spacing between adjacent DL subbands and UL subbands of the partially overlapping SBFD symbol.

[0306] Figure 2E is a resource schematic diagram according to an embodiment of the present disclosure. As shown in Figure 2E, when the first symbol type is partially overlapping SBFD, for example, the frequency domain resource of the sensing signal can be an SSFD sub-band of partially overlapping SBFD symbols, i.e., resource #3 in Figure 2E (SSFD #3 in Figure 2E). In this case, the maximum bandwidth corresponding to the sensing signal is the bandwidth of the SSFD sub-band on CC or the frequency domain range where the bandwidth of the SSFD sub-band on CC overlaps with BWP (the overlapping area is not shown in Figure 2E). The frequency domain resource of the sensing signal can also be an SSFD sub-band, a DL sub-band, and the interval between adjacent SSFD sub-bands and DL sub-bands of partially overlapping SBFD symbols, i.e., resource #1 in Figure 2E (SSFD #1, DL #1 in Figure 2E). In this case, the maximum bandwidth corresponding to the sensing signal is CC or BWP. The frequency domain resources of the sensing signal can also be the SSFD subband, UL subband and the interval between adjacent SSFD subband and UL subband with partially overlapping SBFD symbols, i.e., resource #2 in Figure 2E (SSFD#2, UL#2 in Figure 2E). In this case, the maximum bandwidth corresponding to the sensing signal is CC or BWP.

[0307] In some embodiments, the subband is a subband on CC or the frequency domain range where a subband on CC overlaps with BWP.

[0308] Step S2103: The terminal device transmits the sensing signal on the time domain resources and frequency domain resources used by the sensing signal.

[0309] In some embodiments, transmitting sensing signals may include sending and / or receiving sensing signals.

[0310] It should be noted that the specific methods by which terminal devices send and / or receive sensing signals can be found in the definitions in existing protocols, and will not be elaborated here.

[0311] Using the above method, the terminal device can determine the time-domain resources and / or frequency-domain resources used by the sensing signal based on the first symbol type, and send and / or receive the sensing signal on the time-domain resources and / or frequency-domain resources.

[0312] The methods involved in the embodiments of this disclosure may include at least one of the steps S2101 to S2103 described above. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, and step S2101 + step S2102 may be implemented as an independent embodiment, but are not limited thereto.

[0313] In some embodiments, the order of any two steps in steps S2101 to S2103 can be interchanged or they can be performed simultaneously.

[0314] In some embodiments, steps S2101 to S2103 are optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, step S2103 may be omitted.

[0315] In some embodiments, other alternative implementations may be described before or after the specification corresponding to FIG2A.

[0320] In some embodiments, the terminal device may determine a first time slot set for a first time period based on the first condition.

[0321] In some embodiments, the first time period may be agreed upon by a protocol or indicated by the network device through higher-level configuration or dynamic information.

[0322] In some embodiments, the first time slot set may include time slots that cannot be used for the sensing signal.

[0328] In the time slot, the SSB and the sensing signal overlap in the time domain;

[0329] The time slot includes the random access channel timing (RO).

[0330] The number of symbols between the last symbol of the RO and the first symbol of the sensed signal in the time slot is less than the third threshold;

[0331] The number of symbols between the first symbol of the RO and the last symbol of the sensed signal in the time slot is less than the fourth threshold;

[0332] The RO and the sensing signal overlap in the time domain during the time slot;

[0333] The time slot contains symbols of a third symbol type, which includes at least one of the following: UL, DL, F, non-overlapping SBFD, partially overlapping SBFD, SSFD;

[0334] The symbol interval between the last symbol of the third symbol type preceding the sensing signal in the time slot and the first symbol of the sensing signal is less than the fifth threshold;

[0335] The interval between the first symbol of the third symbol type following the sensed signal in the time slot and the last symbol of the sensed signal is less than the sixth threshold.

[0336] At least one of the symbols containing the sensing signal in the time slot is configured as the third symbol type;

[0337] Reserved time slots;

[0338] The length of the cyclic prefix (CP) of at least one symbol in the symbol containing the sensing signal in the time slot is less than the seventh threshold;

[0339] The frequency domain range of the sensed signal in the time slot overlaps with the UL sub-band.

[0340] The frequency domain range of the sensed signal in the time slot overlaps with the outside of the DL subband.

[0341] In some embodiments, the first threshold, the second threshold, the third threshold, the fifth threshold, the sixth threshold, and the seventh threshold can all be agreed upon by a protocol or indicated by a network device.

[0342] Step S2602: The terminal device determines the third time slot set based on the second time slot set and uses the third time slot set as the time domain resource for sensing signals.

[0343] In some embodiments, the second time slot set includes time slots other than the first time slot set within the first time period.

[0344] In some embodiments, after determining the first time slot set, the time slots in the first time period other than the first time slot set can be used as the second time slot set.

[0345] In some embodiments, after determining the second time slot set, the second time slot set can be used as the third time slot set.

[0346] For example, according to the agreement, the second time slot set can be used as the third time slot set.

[0347] In some embodiments, using the second time slot set as the third time slot set can be understood as using all time slots in the second time slot set as the third time slot set.

[0348] In some embodiments, a third time slot set may be determined from the second time slot set based on the first indication information.

[0349] In some embodiments, the first indication information may be used to select time-domain resources for the sensing signal from the time-domain resources that the sensing signal can use.

[0350] In some embodiments, the time-domain resources that can be used for sensing signals can be understood as time-domain resources other than those that cannot be used for sensing signals.

[0351] In some embodiments, the first indication information may be pre-configured or indicated by the network device.

[0352] In some embodiments, the terminal device may receive the first indication information sent by the network device.

[0353] In some embodiments, the first indication information may include at least one of the following:

[0354] A first bitmap is used to indicate that some or all of the time slots in the second time slot set are used as the third time slot set;

[0355] At least one first configuration information, the first configuration information including at least one of the following: start time slot, number of time slots, end time slot, the first configuration information being used to indicate that some or all of the time slots in the second time slot set are used as the third time slot set;

[0356] At least one first start position and length indicator value (SLIV), which indicates the starting time slot and the number of time slots, and at least one first SLIV is used to indicate that some or all of the time slots in the second time slot set are used as the third time slot set.

[0357] In some embodiments, if the first bitmap indicates that all time slots in the second time slot set are used as the third time slot set, then the time domain resources of the sensing signal can be determined to be all time slots in the second time slot set; if the first bitmap indicates that some time slots in the second time slot set are used as the third time slot set, then the time domain resources of the sensing signal are some time slots in the second time slot set, and some time slots can be one time slot or multiple time slots.

[0358] In some embodiments, the third time slot set can be determined from the second time slot set based on at least one of the start time slot, the number of time slots, and the end time slot included in the first configuration information.

[0359] For example, if the starting time slot is the first time slot of the second time slot set and the ending time slot is the last time slot of the second time slot set, then all time slots of the second time slot set can be used as the third time slot set.

[0360] For example, if the number of time slots is equal to the total number of time slots in the second time slot set, then the total number of time slots in the second time slot set can be used as the third time slot set.

[0361] For example, the starting time slot, the ending time slot, and the time slots in the second time slot set between the starting time slot and the ending time slot can be used as the third time slot set.

[0362] For example, the end time slot can be determined based on the start time slot and the number of time slots, or the start time slot can be determined based on the end time slot and the number of time slots, thereby further determining the third time slot set.

[0363] In some embodiments, the third time slot set can be determined from the second time slot set based on the starting time slot and the number of time slots indicated by the first SLIV. The specific determination method can refer to the above description of determining the third time slot set based on the first configuration information, and will not be repeated here.

[0364] Step S2603: The terminal device determines the first RB set.

[0365] In some embodiments, the first set of RBs may include at least one of the following: RBs contained in CC and RBs contained in BWP.

[0366] Step S2604: The terminal device determines the second RB set based on the first RB set and uses the second RB set as the frequency domain resource for the sensing signal.

[0367] In some embodiments, the second RB set may be a subset of the first RB set. For example, the second RB set may include all the RBs of the first RB set, or, for another example, the second RB set may include some of the RBs of the first RB set.

[0368] In some embodiments, after determining the first RB set, the first RB set can be used as the second RB set.

[0369] For example, according to the agreement, the first RB set can be used as the second RB set.

[0370] In some embodiments, using the first RB set as the second RB set can be understood as using all RBs of the first RB set as the second RB set.

[0371] In some embodiments, a second RB set may be determined from the first RB set based on second indication information.

[0372] In some embodiments, the second indication information may be pre-configured or indicated by the network device.

[0373] In some embodiments, the terminal device may receive the second instruction information sent by the network device.

[0374] In some embodiments, the second indication information may include at least one of the following:

[0375] A second bitmap is used to indicate that some or all of the RBs in the first RB set are used as the second RB set;

[0376] At least one second configuration information, which may include at least one of the following: a starting RB, the number of RBs, and an ending RB, wherein the at least one second configuration information is used to indicate that some or all of the RBs in the first RB set are used as the second RB set;

[0377] At least one second SLIV indicating the starting RB and the number of RBs, and at least one second SLIV indicating that some or all of the RBs in the first RB set are used as the second RB set.

[0378] In some embodiments, if the second bitmap indicates that the first RB set is used as the second RB, then the frequency domain resource of the sensed signal can be determined to be all the RBs of the first RB set; if the second bitmap indicates that some RBs in the first RB set are used as the second RB set, then the frequency domain resource of the sensed signal is some of the RBs of the first RB set, and some RBs can be one RB or multiple RBs.

[0379] In some embodiments, the second RB set can be determined from the first RB set based on at least one of the starting RB, the number of RBs, and the ending RB included in the second configuration information.

[0380] For example, if the starting RB is the first RB of the first RB set and the ending RB is the last RB of the first RB set, then all RBs of the first RB set can be used as the second RB set.

[0381] For example, if the number of RBs is equal to the total number of RBs in the first RB set, then all RBs in the first RB set can be used as the second RB set.

[0382] For example, the starting RB, the ending RB, and the RBs in the first RB set between the starting RB and the ending RB can be used as the second RB set.

[0383] For example, the ending RB can be determined based on the starting RB and the number of RBs, or the starting RB can be determined based on the ending RB and the number of RBs, thereby further determining the second set of RBs.

[0384] In some embodiments, the second RB set can be determined from the first RB set based on the starting RB and the number of RBs indicated by the second SLIV. The specific determination method can be referred to the above description of determining the second RB set based on the second configuration information, and will not be repeated here.

[0385] In some embodiments, when the first condition, the first indication information, and the second indication information are all pre-configured, they can be included in one pre-configuration information, and the terminal device can obtain part of the information in the pre-configuration information; or they can be configured separately, and the terminal device can obtain each pre-configuration information separately.

[0386] In some embodiments, when the first condition, the first indication information, and the second indication information are all indicated by the network device, the network device may indicate them all at once. For example, the network device may send the first indication information and the second indication information simultaneously, or the first indication information and the second indication information may be included in one indication information. Alternatively, the network device may indicate each item separately. This disclosure does not limit the scope of the embodiments.

[0387] Step S2605: The terminal device transmits the sensing signal on the time domain resources and frequency domain resources used by the sensing signal.

[0388] It should be noted that the specific methods by which terminal devices transmit sensing signals can be found in existing protocols, and will not be elaborated here.

[0389] Using the above method, the terminal device can determine the time-domain resources and / or frequency-domain resources used by the sensing signal based on the first condition, the first indication information, and the second indication information, and send and / or receive the sensing signal on the time-domain resources and / or frequency-domain resources.

[0390] The methods involved in the embodiments of this disclosure may include at least one of the steps S2601 to S2605 described above. For example, step S2601 may be implemented as an independent embodiment, step S2602 may be implemented as an independent embodiment, step S2603 may be implemented as an independent embodiment, step S2604 may be implemented as an independent embodiment, step S2605 may be implemented as an independent embodiment, step S2601 + step S2602 may be implemented as an independent embodiment, and step S2603 + step S2604 may be implemented as an independent embodiment, but are not limited thereto.

[0391] In some embodiments, the order of any two steps in steps S2601 to S2605 can be interchanged or they can be performed simultaneously.

[0392] In some embodiments, steps S2601 to S2605 are optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, step S2605 may be omitted.

[0393] Figure 2G is an interactive schematic diagram illustrating a communication method according to an embodiment of the present disclosure. This method can be executed by the aforementioned communication system. As shown in Figure 2G, the method may include:

[0394] Step S2701: The network device determines the time-domain resources used by the sensing signal based on the first symbol type.

[0395] In some embodiments, symbols of the first symbol type can be used as time-domain resources for sensing signals.

[0396] In some embodiments, the first symbol type may be predefined or pre-configured by the network device.

[0397] In some embodiments, the first symbol type may include at least one of the following: DL, UL, F, SBFD, SBFD, SSFD.

[0398] In some embodiments, the time-domain and / or frequency-domain resources used by the sensing signal can be used for a first sensing mode.

[0399] In some embodiments, the first sensing mode may include at least one of the following: a single-station sensing mode and a multi-station sensing mode.

[0400] In some embodiments, the first symbol type may be the same as the second symbol type, which may include at least one of the following: DL, UL, F, SSFD.

[0401] For example, if the first symbol type is DL, the DL symbol can be used as a time-domain resource for the sensing signal; if the first symbol type is UL, the UL symbol can be used as a time-domain resource for the sensing signal; if the first symbol type is F, the F symbol can be used as a time-domain resource for the sensing signal; if the first symbol type is SSFD, the SSFD symbol can be used as a time-domain resource for the sensing signal.

[0402] In some embodiments, "the first symbol type is the same as the second symbol type" can be understood as the first symbol type including at least one of the following: DL, UL, F, SSFD, that is, the first symbol type does not include non-overlapping SBFD and partially overlapping SBFD.

[0403] In some embodiments, SSFD symbols can be used simultaneously for DL ​​signal and UL signal transmission on the same frequency domain resources.

[0404] In some embodiments, the first symbol type is a non-overlapping SBFD.

[0405] In some embodiments, the first symbol type is a partially overlapping SBFD.

[0406] Step S2702: The network device determines the frequency domain resources used by the sensing signal.

[0407] In some embodiments, if the first symbol type is the same as the second symbol type, the frequency domain resources used by the sensed signal may include at least one of the following: the frequency domain range of the carrier component (CC) and the frequency domain range of the bandwidth part (BWP).

[0408] As shown in Figure 2B, the sensing resource represents the frequency domain resources that the sensing signal can use. For example, when the first symbol type is DL, the frequency domain resource of the sensing signal can be resource #1 (DL#1 in Figure 2B), and when the second symbol type is UL, the frequency domain resource of the sensing signal can be resource #2 (UL#2 in Figure 2B).

[0409] As shown in Figure 2C, when the first symbol type is SSFD, for example, the frequency domain resource of the sensed signal can be resource #1 (SSFD#1 in Figure 2C).

[0410] In some embodiments, if the first symbol type is a non-overlapping SBFD, the frequency domain resources used by the sensed signal may include at least one of the following:

[0411] DL subbands with non-overlapping SBFD symbols;

[0412] UL sub-bands with non-overlapping SBFD symbols;

[0413] The DL subband, UL subband, and first frequency domain spacing of the non-overlapping SBFD symbol, wherein the first frequency domain spacing may be the frequency domain spacing between the DL subband and UL subband on the non-overlapping SBFD symbol.

[0414] In some embodiments, a non-overlapping SBFD symbol is a symbol of type non-overlapping SBFD.

[0415] For example, if the first symbol type is non-overlapping SBFD, the frequency domain resources used by the sensing signal can be the DL subband of the non-overlapping SBFD symbol, the UL subband of the non-overlapping SBFD symbol, or the DL subband, UL subband, and frequency domain spacing between the DL subband and UL subband of the non-overlapping SBFD symbol.

[0416] As shown in Figure 2D, when the first symbol type is a non-overlapping SBFD, for example, the frequency domain resource of the sensing signal can be the DL subband of the non-overlapping SBFD symbol, i.e., resource #2 in Figure 2D (DL#2 in Figure 2D). In this case, the maximum bandwidth corresponding to the sensing signal is the bandwidth of the two DL subbands on CC or the frequency domain range where the bandwidth of the two DL subbands on CC overlaps with BWP (the overlapping area is not shown in Figure 2D). The frequency domain resource of the sensing signal can also be the UL subband of the non-overlapping SBFD symbol, i.e., resource #1 in Figure 2D (UL#1 in Figure 2D). In this case, the maximum bandwidth corresponding to the sensing signal is the bandwidth of the UL subband or the frequency domain range where the bandwidth of the UL subband on CC overlaps with BWP (the overlapping area is not shown in Figure 2D). The frequency domain resources of the sensing signal can also be the DL subband, UL subband and frequency domain spacing between the DL subband and UL subband with non-overlapping SBFD symbols, i.e., resource #3 in Figure 2D (UL#3 and DL#3 in Figure 2D). In this case, the maximum bandwidth corresponding to the sensing signal is CC or BWP.

[0417] In some embodiments, the non-overlapping SBFD symbol may include a DL subband and a UL subband, and the DL subband and the UL subband do not overlap in the frequency domain.

[0418] In some embodiments, if the first symbol type is partially overlapped SBFD, the frequency domain resources used by the sensed signal may include at least one of the following:

[0419] SSFD subbands with partially overlapping SBFD symbols;

[0420] The SSFD subband, DL subband, and second frequency domain spacing of partially overlapping SBFD symbols, wherein the second frequency domain spacing is the spacing between adjacent SSFD subbands and DL subbands on the partially overlapping SBFD symbols;

[0421] The overlapping SBFD symbols include the SSFD subband, UL subband, and third frequency domain spacing, where the third frequency domain spacing is the spacing between adjacent SSFD subbands and UL subbands on the overlapping SBFD symbols.

[0422] The overlapping SBFD symbols include the SSFD subband, DL subband, UL subband, and a fourth frequency domain interval. The fourth frequency domain interval is the interval between adjacent subbands on the overlapping SBFD symbols. The adjacent subbands may include two adjacent subbands among the SSFD subband, DL subband, and UL subband.

[0423] In some embodiments, a partially overlapping SBFD symbol is a symbol of type partially overlapping SBFD.

[0424] In one implementation, if the first symbol type is partially overlapping SBFD, then the frequency domain resources used by the sensing signal can be the SSFD subband of partially overlapping SBFD symbols.

[0425] In another implementation, if the first symbol type is partially overlapping SBFD, the frequency domain resources used by the sensing signal can be the SSFD subband, DL subband, and the interval between adjacent SSFD subbands and DL subbands of the partially overlapping SBFD symbols.

[0426] In another implementation, if the first symbol type is partially overlapping SBFD, the frequency domain resources used by the sensing signal can be the SSFD subband, UL subband, and the spacing between adjacent SSFD subbands and UL subbands of the partially overlapping SBFD symbols.

[0427] In another implementation, if the first symbol type is partially overlapping SBFD, the frequency domain resources used by the sensing signal can be the SSFD sub-band, DL sub-band, UL sub-band of the partially overlapping SBFD symbol, as well as the intervals between adjacent SSFD sub-bands and DL sub-bands, the intervals between adjacent SSFD sub-bands and UL sub-bands, and the intervals between adjacent DL sub-bands and UL sub-bands.

[0428] In some embodiments, the frequency domain distribution of partially overlapping SBFD symbols includes at least one of the following:

[0429] It includes DL subband and SSFD subband. The DL subband and SSFD subband do not overlap in the frequency domain. The SSFD subband can be used for DL ​​signal and UL signal transmission at the same time.

[0430] It includes UL subband and SSFD subband, and the UL subband and SSFD subband do not overlap in the frequency domain;

[0431] It includes DL subband, UL subband and SSFD subband, and the different types of subbands do not overlap in the frequency domain.

[0432] For example, if a partially overlapping SBFD symbol contains a DL subband and an SSFD subband, the frequency domain resources used by the sensing signal are the SSFD subband, DL subband, and the spacing between adjacent SSFD subbands and DL subbands of the partially overlapping SBFD symbol; if a partially overlapping SBFD symbol contains a UL subband and an SSFD subband, the frequency domain resources used by the sensing signal may be the SSFD subband, UL subband, and the spacing between adjacent SSFD subbands and UL subbands of the partially overlapping SBFD symbol; if a partially overlapping SBFD symbol contains a DL subband, UL subband, and SSFD subband, the frequency domain resources used by the sensing signal may be the SSFD subband, DL subband, UL subband, and the spacing between adjacent SSFD subbands and DL subbands, the spacing between adjacent SSFD subbands and UL subbands, and the spacing between adjacent DL subbands and UL subbands of the partially overlapping SBFD symbol.

[0433] As shown in Figure 2E, when the first symbol type is partially overlapping SBFD, for example, the frequency domain resource of the sensing signal can be the SSFD sub-band of the partially overlapping SBFD symbols, i.e., resource #3 in Figure 2E (SSFD #3 in Figure 2E). In this case, the maximum bandwidth corresponding to the sensing signal is the bandwidth of the SSFD sub-band on CC or the frequency domain range where the bandwidth of the SSFD sub-band on CC overlaps with BWP (the overlapping area is not shown in Figure 2E). The frequency domain resource of the sensing signal can also be the SSFD sub-band, DL sub-band, and the interval between adjacent SSFD sub-bands and DL sub-bands of the partially overlapping SBFD symbols, i.e., resource #1 in Figure 2E (SSFD #1, DL #1 in Figure 2E). In this case, the maximum bandwidth corresponding to the sensing signal is CC or BWP. The frequency domain resources of the sensing signal can also be the SSFD subband, UL subband and the interval between adjacent SSFD subband and UL subband with partially overlapping SBFD symbols, i.e., resource #2 in Figure 2E (SSFD#2, UL#2 in Figure 2E). In this case, the maximum bandwidth corresponding to the sensing signal is CC or BWP.

[0434] In some embodiments, the subband is a subband on CC or the frequency domain range where a subband on CC overlaps with BWP.

[0435] Step S2703: The network device transmits the sensing signal on the time domain resources and frequency domain resources used by the sensing signal.

[0436] In some embodiments, transmitting sensing signals may include sending and / or receiving sensing signals.

[0437] It should be noted that the specific methods by which network devices send and / or receive sensing signals can be found in the definitions in existing protocols, and will not be elaborated here.

[0438] Using the above method, the network device can determine the time-domain resources and / or frequency-domain resources used by the sensing signal based on the first symbol type, and send and / or receive the sensing signal on the time-domain resources and / or frequency-domain resources.

[0439] The methods involved in the embodiments of this disclosure may include at least one of the steps S2701 to S2703 described above. For example, step S2701 may be implemented as a standalone embodiment, step S2702 may be implemented as a standalone embodiment, step S2703 may be implemented as a standalone embodiment, and step S2701 + step S2702 may be implemented as a standalone embodiment, but are not limited thereto.

[0440] In some embodiments, the order of any two steps in steps S2701 to S2703 can be interchanged or they can be performed simultaneously.

[0441] In some embodiments, steps S2701 to S2703 are optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, step S2703 may be omitted.

[0442] Figure 2H is an interactive schematic diagram illustrating a communication method according to an embodiment of the present disclosure. This method can be executed by the aforementioned communication system. As shown in Figure 2H, the method may include:

[0443] Step S2801: The network device determines the first time slot set according to the first condition.

[0444] In some embodiments, the first condition may be used to determine time-domain resources that cannot be used to sense signals.

[0445] In some embodiments, the first condition may be pre-configured or indicated by the network device. For example, the first condition may be a protocol stipulation.

[0446] In some embodiments, the network device may determine a first time slot set for a first time period based on the first condition.

[0447] In some embodiments, the first time period may be agreed upon by a protocol or indicated by the network device through higher-level configuration or dynamic information.

[0448] In some embodiments, the first time slot set may include time slots that cannot be used for the sensing signal.

[0449] In some embodiments, the network device may determine, from the time slots of a first time period, the time slots that satisfy the first condition, as the first time slot set.

[0450] In some embodiments, the first condition may include at least one of the following:

[0451] The time slot contains a synchronization signal block (SSB).

[0452] The number of symbols between the last symbol of the SSB and the first symbol of the sensed signal in the time slot is less than the first threshold.

[0453] The number of symbols between the first symbol of the SSB and the last symbol of the sensed signal in the time slot is less than the second threshold.

[0454] In the time slot, the SSB and the sensing signal overlap in the time domain;

[0455] The time slot includes the random access channel timing (RO).

[0456] The number of symbols between the last symbol of the RO and the first symbol of the sensed signal in the time slot is less than the third threshold;

[0457] The number of symbols between the first symbol of the RO and the last symbol of the sensed signal in the time slot is less than the fourth threshold;

[0458] The RO and the sensing signal overlap in the time domain during the time slot;

[0459] The time slot contains symbols of a third symbol type, which includes at least one of the following: UL, DL, F, non-overlapping SBFD, partially overlapping SBFD, SSFD;

[0460] The symbol interval between the last symbol of the third symbol type preceding the sensing signal in the time slot and the first symbol of the sensing signal is less than the fifth threshold;

[0461] The interval between the first symbol of the third symbol type following the sensed signal in the time slot and the last symbol of the sensed signal is less than the sixth threshold.

[0462] At least one of the symbols containing the sensing signal in the time slot is configured as the third symbol type;

[0463] Reserved time slots;

[0464] The length of the cyclic prefix (CP) of at least one symbol in the symbol containing the sensing signal in the time slot is less than the seventh threshold;

[0465] The frequency domain range of the sensed signal in the time slot overlaps with the UL sub-band.

[0466] The frequency domain range of the sensed signal in the time slot overlaps with the outside of the DL subband.

[0467] In some embodiments, the first threshold, the second threshold, the third threshold, the fifth threshold, the sixth threshold, and the seventh threshold can all be agreed upon by a protocol or indicated by a network device.

[0468] Step S2802: The network device determines the third time slot set based on the second time slot set and uses the third time slot set as the time domain resource for sensing signals.

[0469] In some embodiments, the second time slot set includes time slots other than the first time slot set within the first time period.

[0470] In some embodiments, after determining the first time slot set, the time slots in the first time period other than the first time slot set can be used as the second time slot set.

[0471] In some embodiments, after determining the second time slot set, the second time slot set can be used as the third time slot set.

[0472] For example, according to the agreement, the second time slot set can be used as the third time slot set.

[0473] In some embodiments, using the second time slot set as the third time slot set can be understood as using all time slots in the second time slot set as the third time slot set.

[0474] In some embodiments, the network device may use the second time slot set as the third time slot set.

[0475] In some embodiments, a network device may use some or all of the time slots of the second time slot set as the third time slot set.

[0476] In some embodiments, if all time slots in the second time slot set are taken as the third time slot set, the time domain resources of the sensing signal can be determined to be all time slots in the second time slot set; if some time slots in the second time slot set are taken as the third time slot set, the time domain resources of the sensing signal are some time slots in the second time slot set, and some time slots can be one time slot or multiple time slots.

[0477] In some embodiments, the network device may determine the third time slot set from the second time slot set based on the first configuration information.

[0478] In some embodiments, the first configuration information may include at least one of the following: the start time slot, the number of time slots, and the end time slot.

[0479] In some embodiments, the third time slot set can be determined from the second time slot set based on at least one of the start time slot, the number of time slots, and the end time slot included in the first configuration information.

[0480] For example, if the starting time slot is the first time slot of the second time slot set and the ending time slot is the last time slot of the second time slot set, then all time slots of the second time slot set can be used as the third time slot set.

[0481] For example, if the number of time slots is equal to the total number of time slots in the second time slot set, then the total number of time slots in the second time slot set can be used as the third time slot set.

[0482] For example, the starting time slot, the ending time slot, and the time slots in the second time slot set between the starting time slot and the ending time slot can be used as the third time slot set.

[0483] For example, the end time slot can be determined based on the start time slot and the number of time slots, or the start time slot can be determined based on the end time slot and the number of time slots, thereby further determining the third time slot set.

[0484] In some embodiments, the network device may indicate to the terminal device how the third time slot set is determined.

[0485] In some embodiments, the network device may send first instruction information to the terminal device.

[0486] In some embodiments, the first indication information may include at least one of the following:

[0487] A first bitmap is used to indicate that some or all of the time slots in the second time slot set are used as the third time slot set;

[0492] Step S2804: The network device determines the second RB set based on the first RB set and uses the second RB set as the frequency domain resource for sensing signals.

[0493] In some embodiments, the second RB set may be a subset of the first RB set. For example, the second RB set may include all the RBs of the first RB set, or, for another example, the second RB set may include some of the RBs of the first RB set.

[0494] In some embodiments, after determining the first RB set, the first RB set can be used as the second RB set.

[0495] For example, according to the agreement, the first RB set can be used as the second RB set.

[0498] In some embodiments, if the first set of RBs is used as the second set of RBs, then the frequency domain resources of the sensed signal can be determined to be all the RBs of the first set of RBs; if a portion of the RBs in the first set of RBs is used as the second set of RBs, then the frequency domain resources of the sensed signal are a portion of the RBs of the first set of RBs. The portion of RBs can be one RB or multiple RBs.

[0500] In some embodiments, the second configuration information may include at least one of the following: starting RB, number of RBs, and ending RB.

[0501] For example, if the starting RB is the first RB of the first RB set and the ending RB is the last RB of the first RB set, then all RBs of the first RB set can be used as the second RB set.

[0502] For example, if the number of RBs is equal to the total number of RBs in the first RB set, then all RBs in the first RB set can be used as the second RB set.

[0503] For example, the starting RB, the ending RB, and the RBs in the first RB set between the starting RB and the ending RB can be used as the second RB set.

[0504] For example, the ending RB can be determined based on the starting RB and the number of RBs, or the starting RB can be determined based on the ending RB and the number of RBs, thereby further determining the second set of RBs.
