[0046] With reference to some embodiments of the first aspect, in some embodiments, resource subsets in spectrum resources corresponding to different reference signals are divided in the same or different ways.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, determining the fourth information includes at least one of the following:

Optionally, when the terminal is an SL reference signal receiving end, the terminal will receive third information, for example, the terminal will receive the third information sent by the SL reference signal sending end, and the third information is used to determine the resources occupied by the SL reference signal.

In summary, the present disclosure provides a determination method for determining the resources occupied by the reference signal in the shared spectrum resources, so as to achieve successful transmission of the reference signal on the shared spectrum resources, thereby ensuring the accuracy of related services. For example, when the reference signal is a reference signal for positioning purposes, the successful transmission of the reference signal on the shared spectrum resources can improve the measurement accuracy of the reference signal for positioning purposes, thereby improving the positioning accuracy.

[0199] The following are explanations of the terms used in this disclosure:

[0200] FIG1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in FIG1 , the communication system 100 may include at least one of a terminal 101 and a first device 102. The first device may include at least one of an access network device (e.g., a base station and / or a transmission reception point (TRP)) 1021, a terminal 1022, a positioning reference unit (PRU) 1023, and a core network device (e.g., a location management function (LMF)) 1024.

[0201] In some embodiments, the terminal includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0202] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0203] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0204] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0205] In some embodiments, the core network device may be a device including one or more network elements, or may be multiple devices or a group of devices, each including all or part of one or more network elements. The network element may be virtual or physical. The core network, for example, includes at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC). Alternatively, the core network device may also be a location management function network element. Exemplarily, the location management function network element includes a location server (location server), which may be implemented as any one of the following: Location Management Function (LMF), Enhanced Serving Mobile Location Centre (E-SMLC), Secure User Plane Location (SUPL), and Secure User Plane Location Platform (SUPLLP).

[0206] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0207] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0208] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other resource determination methods, and next-generation systems based on and extending these systems. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0209] Optionally, in a communication system, for downlink positioning measurement, the introduced positioning reference signal may be: downlink positioning reference signal (PRS); for uplink positioning measurement, the introduced positioning reference signal may be: sounding reference signal (SRS); for sidelink (SL) measurement, the introduced positioning reference signal may be: SL PRS and / or SL SRS; optionally, in some embodiments, in order to improve positioning bandwidth and spectrum utilization, it is necessary to introduce the sending and receiving of positioning reference signals based on unlicensed spectrum. Among them, unlicensed spectrum and shared spectrum can be replaced with each other. Optionally, on the unlicensed spectrum, the transmitter needs to perform listen before talk (LBT) to monitor the channel conditions of the unlicensed spectrum before sending the positioning reference signal on the spectrum resources corresponding to the positioning reference signal. Optionally, the transmitter needs to first monitor the energy on the unlicensed spectrum. If the energy intensity is lower than the threshold, it means that the channel of the unlicensed spectrum is not occupied by other devices, that is, the channel of the unlicensed spectrum is in an idle state, and LBT is successful. At this time, the transmitter will send the positioning reference signal. If the energy intensity is higher than the threshold, it means that the channel of the unlicensed spectrum is occupied by other devices, that is, the channel of the unlicensed spectrum is in a busy state, and LBT fails. At this time, the transmitter cannot use the unlicensed spectrum to send the positioning reference signal. Among them, LBT can be interchangeable with the channel access process.

[0210] However, in some embodiments, the bandwidth of the LBT detection unit is limited to a maximum value, such as 20 MHz, and the bandwidth of the spectrum resources configured for sending the positioning reference signal may be greater than the maximum value. In this case, the transmitter will perform LBT detection independently in each detection unit. For example, if the spectrum resource corresponding to the positioning reference signal is 60 MHz, the transmitter will perform LBT detection independently in the first 20 MHz, the middle 20 MHz, and the last 20 MHz of the spectrum resource. As a result, some 20 MHz are detected as LBT idle, and some are detected as LBT busy. In this case, how the transmitter indicates the spectrum resources occupied by the final transmission (that is, how to indicate to the receiving end the one or more 20 MHz spectrum resources occupied by the final transmission of the positioning reference signal, so that the receiving end receives the positioning reference signal on the corresponding spectrum resources based on the indication) is a problem that needs to be solved.

[0211] FIG2A is an interactive diagram illustrating a resource determination method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a resource determination method for a communication system 100, the method comprising:

[0212] Step 2101: The terminal determines the spectrum resources corresponding to the reference signal.

[0213] Optionally, in some embodiments, the spectrum resource may be a shared spectrum resource, wherein the shared spectrum may be interchangeable with an unlicensed spectrum.

[0214] Optionally, the spectrum resource corresponding to the reference signal can be a resource used to send a reference signal. Optionally, the reference signal transmitter can perform LBT detection in the spectrum resource, and for the resource in the spectrum resource where the LBT detection is successful, a reference signal can be sent on the resource.

[0215] Optionally, in some embodiments, the method for the terminal to determine the spectrum resources corresponding to the reference signal may include at least one of the following: when the reference signal is PRS, first configuration information sent by the core network device (such as LMF) is received, and the first configuration information is used to determine the spectrum resources corresponding to the PRS; when the reference signal is SRS, second configuration information is received from the access network device (such as a base station and / or TRP), and the second configuration information is used to determine the spectrum resources corresponding to the SRS; when the reference signal is SL SRS, third configuration information is received from at least one of the access network device, the core network device, the opposite terminal, and the PRU, and the third configuration information is used to determine the spectrum resources corresponding to the SL SRS; when the reference signal is SL PRS, fourth configuration information is received from at least one of the access network device, the core network device, the opposite terminal, and the PRU, and the fourth configuration information is used to determine the spectrum resources corresponding to the SL PRS.

[0216] Optionally, in some embodiments, when the above-mentioned first configuration information, second configuration information or third configuration information is sent by a core network device, the first configuration information, second configuration information or third configuration information may be sent by a Long Term Evolution Positioning Protocol (LPP) message, for example, the first configuration information, second configuration information or third configuration information may be carried by an LPP message; when the above-mentioned first configuration information, second configuration information or third configuration information is sent by an access network device, the first configuration information, second configuration information or third configuration information may be sent by at least one of Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC CE) signaling, and Downlink Control Information (DCI) signaling; when the above-mentioned first configuration information, second configuration information or third configuration information is sent by a peer terminal or PRU, the first configuration information, second configuration information or third configuration information may be sent by SL RRC, SL MAC CE, SL Sidelink Control Information (DCI) signaling. It is sent by at least one of the physical sidelink shared channel (PSSCH) and the physical sidelink control channel (PSCCH).

[0217] Optionally, in some embodiments, the first configuration information, the second configuration information or the third configuration information is also used to configure at least one of the following: time domain parameters of the reference signal; frequency domain parameters of the reference signal; comb parameters of the reference signal; power control parameters of the reference signal; quasi-co-located (QCL) information of the reference signal; spatial relationship information of the reference signal; resource identification (ID) of the reference signal; and resource set ID of the reference signal.

[0218] Optionally, in some embodiments, the time domain parameter may include at least one of the following: a period; a starting time slot; a starting symbol; a number of occupied symbols; a number of repeated transmissions; and an interval value between repeated transmissions.

[0219] Optionally, in some embodiments, the frequency domain parameter may include at least one of the following: a frequency domain position; a frequency domain offset; a frequency hopping mode. The frequency domain parameter may be used to determine the above-mentioned spectrum resources.

[0220] Optionally, in some embodiments, the comb parameter may include at least one of the following: a comb value; a cyclic shift.

[0221] Optionally, in some embodiments, the power control parameter may include at least one of the following: a P0 value; an alpha value; a path loss reference signal pathloss RS or PathlossReferenceRS.

[0222] Optionally, in some embodiments, the spectrum resources corresponding to different reference signals configured in the configuration information (i.e., the aforementioned first configuration information, second configuration information, or third configuration information) are the same or different. For example, for PRS, the spectrum resources corresponding to different PRS resource sets in the configuration information may be the same or different. Since PRS is sent by an access network device TRP, a single access network device TRP may correspond to one or more PRS resource sets, and different PRS resource sets may correspond to the same TRP or different TRPs. Therefore, the spectrum resources in the configuration information may be the same or different for different PRS resource sets. Alternatively, for SRS, the spectrum resources corresponding to different SRS resources in the configuration information may be the same or different. Because different SRSs are sent by a terminal to different access network devices, the spectrum resources configured in the configuration information for SRSs communicated between the terminal and different access network devices may be the same or different. Alternatively, for SL SRS or SL PRS, which are sent by a terminal to a peer terminal or PRU, the spectrum resources configured in the configuration information for SL SRS or SL PRSs communicated between the terminal and different peer terminals or different PRUs may be the same or different.

[0223] Optionally, in some embodiments, reference signals corresponding to different TRPs may be distinguished by using different reference signal identifiers. For example, PRSs transmitted between different access network devices and terminals may be distinguished by using different PRS IDs.

[0224] Step 2102: The terminal determines at least one resource subset included in the spectrum resources.

[0225] Optionally, the spectrum resources are divided into at least one resource subset, and the reference signal transmitter performs LBT detection on each resource subset. For the resource subset in the spectrum resources where LBT detection is successful, the reference signal transmitter can transmit a reference signal on the resource subset.

[0226] Optionally, in some embodiments, the method for the terminal to determine at least one resource subset included in the spectrum resources may include:

[0227] Determine fourth information; the fourth information can be used to indicate the division method of resource subsets; optionally, the fourth information includes at least one of the following: the starting position of each resource subset; the bandwidth of each resource subset; the ending position of each resource subset; the starting position of the interval resource between two adjacent resource subsets; the bandwidth of the interval resource between two adjacent resource subsets; the ending position of the interval resource between two adjacent resource subsets.

[0228] Optionally, when the fourth information includes the starting position of the interval resource between two adjacent resource subsets and the ending position of the interval resource between two adjacent resource subsets, at least one resource subset included in the spectrum resource can be determined in the following manner: Optionally, the starting position of the first resource subset is the same as the starting position of the spectrum resource, and the ending position of the first resource subset is the starting position of the first interval frequency domain (i.e., the interval resource between the first resource subset and the second resource subset); the starting position of the second resource subset is the ending position of the first interval frequency domain, and the ending position of the second resource subset is the starting position of the second interval frequency domain (i.e., the interval resource between the second resource subset and the third resource subset), and so on, to determine the starting position and ending position of each resource subset.

[0229] Optionally, in some embodiments, the method for determining the fourth information may include at least one of the following:

[0230] The reference signal is a PRS, and the fourth information is determined based on at least one of transmission by a core network device, transmission by an access network device, a protocol agreement, and a default rule;

[0231] The reference signal is an SRS, and the fourth information is determined based on at least one of transmission by an access network device, a protocol agreement, and a default rule;

[0232] The reference signal is an SL SRS, and the fourth information is determined based on at least one of transmission by a core network device, transmission by an access network device, transmission by a peer terminal, transmission by a PRU, a protocol agreement, and a default rule;

[0234] Optionally, in some embodiments, the resource subsets in the spectrum resources corresponding to different reference signals are divided in the same or different ways.

[0236] Optionally, in some embodiments, the downlink reference signal may be a PRS, and the first information may be used to determine the resources occupied by the downlink reference signal. For example, the resources determined by the first information may be a first resource subset of spectrum resources, and the first resource subset determined by the first information may be a resource subset occupied during downlink reference signal transmission; wherein the resources determined by the first information are shared spectrum resources. Optionally, the first device may send the first information to a terminal. Optionally, the first device may include at least one of the following: a core network device; or an access network device.

[0237] Optionally, in some embodiments, since the downlink reference signal is sent by the access network device to the terminal, the first information will be determined by the access network device (i.e., the transmitter of the reference signal).

Optionally, in some embodiments, after the access network device determines the first information, it may directly send the first information to the terminal, or the access network device may also send the first information to the core network device, and then the core network device sends the first information to the terminal.

For example, when the bit value carried by the bit is a first value (such as 1), it indicates that the resource subset corresponding to the bit is the first resource subset; when the bit value carried by the bit is a second value (such as 0), it indicates that the resource subset corresponding to the bit is not the first resource subset.

[0240] Optionally, in some other embodiments, the first information may include at least one indicator code; wherein different indicator codes correspond to at least one resource subset, respectively. Optionally, the indicator code may correspond to at least one continuous resource subset, or the indicator code may correspond to at least one non-contiguous resource subset, and the indicator code included in the first information is the indicator code corresponding to the first resource subset. Optionally, the indicator code may be a codepoint.

[0241] Optionally, in some embodiments, the first information may include any channel and / or other reference signals other than a reference signal (the other reference signal may be, for example, a channel-state information reference signal (CSI-RS)); optionally, the resources occupied by the channel and / or other reference signals may be used to determine the first resource subset. Optionally, the first resource subset may be included in the resources occupied by the channel and / or other reference signals, or the resources occupied by the channel and / or other reference signals included in the first information may be equivalent to the resources occupied by the downlink reference signal. Optionally, the first information may include at least one of any downlink channel and any other downlink reference signal other than a PRS. The downlink channel may include at least one of a physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH). For example, if the resources occupied by the downlink channel and / or other downlink reference signals are the first resource set, then the resource subset occupied by the PRS (i.e., the aforementioned first resource subset) is less than or equal to the first resource set.

[0242] Optionally, in some other embodiments, the first information may further include: first information corresponding to the current serving cell, and / or first information corresponding to a neighboring cell; wherein the first information corresponding to the current serving cell is used to determine the resources occupied by the PRS of the current serving cell; and the first information corresponding to the neighboring cell is used to determine the resources occupied by the PRS of the neighboring cell. Optionally, the first information corresponding to the neighboring cell may be sent by the neighboring cell (such as the access network device of the neighboring cell) to the first device corresponding to the current serving cell. Or the first information corresponding to the neighboring cell may be sent by the neighboring cell (such as the access network device of the neighboring cell) to the core network device, and then the core network device sends the first information corresponding to the neighboring cell to the first device corresponding to the current serving cell.

[0243] Optionally, in some embodiments, the first information corresponding to different downlink reference signals is different or the same. For example, the downlink reference signal is sent by an access network device to a terminal, wherein the first information corresponding to the downlink reference signals transmitted between different access network devices and the terminal may be the same or different.

[0434] Figure 5 is a flow chart of a resource determination method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a resource determination method for a communication system including a first device and a terminal.

[0435] Step 5101: The first device sends resource configuration information, where the resource configuration information is used to determine a spectrum resource corresponding to a reference signal, where the spectrum resource is a shared spectrum resource.

[0436] Step 5102: The terminal determines the spectrum resources corresponding to the reference signal based on the resource configuration information.

[0437] Optional implementations of steps 5101 to 5108 may refer to the steps in any one or more of the embodiments in FIG. 2A and FIG. 3A to FIG. 3E , and other related parts of the embodiments involved in FIG. 4A to FIG. 4E .

[0438] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0439] The resource determination method involved in the embodiments of the present disclosure may include at least one of steps S5101 to S5108. For example, step S5101 may be implemented as an independent embodiment, step S5102 may be implemented as an independent embodiment, and steps S5101+S5102 may be implemented as independent embodiments, but are not limited thereto.

[0440] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0441] The following is an exemplary introduction to the above method.

[0442] If the positioning reference signal is a PRS:

[0443] 1. The terminal receives frequency domain resource indication information of the PRS sent by the network device, which is used to indicate which frequency domain resource subsets of the configured frequency domain resources are occupied by the PRS.

[0444] The configured frequency domain resources are determined based on the PRS configuration information sent by the LMF through the LPP, and the frequency domain resource subset included in the configured frequency domain resources is determined by the network configuration (LMF or base station) or the default rule.

[0445] For example, the network configures the starting position, bandwidth, and / or ending position of each frequency domain resource subset; generally, only one of the bandwidth and ending position is required;

[0446] Alternatively, the network device configures the starting position and bandwidth or ending position of the interval frequency domain between each two frequency domain resource subsets. Because the starting position of the first frequency domain resource subset is the same as the starting position of the configured frequency domain resources, and the ending position of the first frequency domain resource subset is the starting position of the first interval frequency domain; the starting position of the second frequency domain resource subset is the ending position of the first interval frequency domain, and the ending position of the second frequency domain resource subset is the starting position of the second interval frequency domain, and so on.

[0447] Or default rules or protocol provisions, the protocol stipulates the bandwidth of each resource subset and the bandwidth of the interval frequency domain.

[0448] It should be noted that the resource subsets of the PRS resources of each TRP are divided in the same way. The specification may also include different situations.

[0449] 2. Frequency domain resource indication information is indicated by TRP (priority DCI) or LMF, indicating the frequency domain resource indication information on at least one TRP

[0450] The TRP indication is a base station indication, including at least one of RRC, MACCE and DCI; DCI is prioritized, and DCI includes groupcommonDCI and UEspecificDCI.

[0451] LMF indication is the transmission of indication information through the LPP protocol.

[0452] 3. Specific design of frequency domain resource indication information:

[0453] Different frequency domain resource subsets correspond to different bits. If the bit value is 1, it indicates that the frequency domain resource subset is available, otherwise it indicates that the frequency domain resource subset is not available. Or the other way around is also possible.

[0454] Or different codepoints correspond to different frequency domain resource subsets. The advantage of this method is that if only multiple consecutive frequency domain resource subsets are supported, the number of bits required is less than the number of bits corresponding to 1 bit for each frequency domain resource subset. Therefore, some restrictions are imposed on the multiple frequency domain resource subsets indicated by the frequency domain resource indication information: contiguous frequency domain resource subsets are preferred, but non-contiguous frequency domain resource subsets are not excluded.

[0455] 4. Different TRPs correspond to different frequency domain resource indication information, including serving cell TRP and / or neighboring cell TRP.

[0456] The serving cell indicates the frequency domain resource indication information of the serving cell, and the serving cell can also indicate the frequency domain resource indication information of the neighboring cell; if it is an LMF indication, the LMF indicates the frequency domain resource indication information of the TRP corresponding to the serving cell and the neighboring cell.

[0457] The PRS resources corresponding to different TRPs are distinguished by different PRSIDs.

[0458] If the positioning reference signal is SRS:

[0459] 5. The terminal sends the frequency domain resource indication information corresponding to the SRS, which is used to indicate which frequency domain resource subsets of the configured frequency domain resources are occupied by the SRS

[0460] The configured resources are configured by the base station through at least one of RRC signaling, MACCE and DCI. The frequency domain resource subset included in the configured frequency domain resources is determined by network configuration (base station) or default rules.

[0461] For example, the network configures the starting position, bandwidth, and / or ending position of each frequency domain resource subset;

[0462] Generally, only one of the bandwidth and termination location is required;

[0463] Or the network device configures the starting position and bandwidth or the ending position of the interval frequency domain between each two frequency domain resource subsets.

[0464] Because the starting position of the first frequency domain resource subset is the same as the starting position of the configured frequency domain resource, and the ending position of the first frequency domain resource subset is the starting position of the first interval frequency domain; the starting position of the second frequency domain resource subset is the ending position of the first interval frequency domain, and the ending position of the second frequency domain resource subset is the starting position of the second interval frequency domain, and so on.

[0465] Or default rules or protocol provisions, the protocol stipulates the bandwidth of each resource subset and the bandwidth of the interval frequency domain.

[0466] It should be noted that: the resource subset division method of SRS sent to different TRPs is the same, the resources of SRS sent to different TRPs are included in one SRS resource set, or the beam directions corresponding to SRS resources sent to different TRPs are different.

[0467] 6. Frequency domain resource indication information is sent to the gNB (prioritized by UCI) or LMF. If beam-based SRS transmission is used, the frequency domain resource indication information on at least one beam is indicated.

[0468] If sent to the gNB, it is based on at least one of UCI, MACCE, and RRC; UCI is prioritized, and PUCCH is prioritized, but PUSCH is not excluded.

[0469] Sent to LMF is based on the LPP protocol.

[0470] 7. Specific design of frequency domain resource indication information:

[0471] Different frequency domain resource subsets correspond to different bits. If the bit value is 1, it indicates that the frequency domain resource subset is available, otherwise it indicates that the frequency domain resource subset is not available. Or the other way around is also possible.

[0472] Or different codepoints correspond to different frequency domain resource subsets. The advantage of this method is that if only multiple consecutive frequency domain resource subsets are supported, the number of bits required is less than the number of bits corresponding to 1 bit for each frequency domain resource subset. Therefore, some restrictions are imposed on the multiple frequency domain resource subsets indicated by the frequency domain resource indication information: contiguous frequency domain resource subsets are preferred, but non-contiguous frequency domain resource subsets are not excluded.

[0473] 8. Different beams correspond to different frequency domain resource indication information, and different beam directions correspond to different TRPs

[0474] If the positioning reference signal is SLPRS or SLSRS:

[0475] 9. The first terminal (which can be a general terminal or a PRU, positioning reference unit) receives frequency domain resource indication information of SL-PRS / SL-SRS sent by at least one second terminal (which can be a general terminal or a PRU, positioning reference unit), which is used to indicate which frequency domain resource subsets of the configured frequency domain resources are occupied by SL-PRS / SL-SRS.

[0476] The configured frequency domain resources are determined based on the PRS configuration information sent by the LMF through the LPP, or the configured frequency domain resources are determined by the base station based on at least one of RRC, MACCE and DCI, or the configured frequency domain resources are determined by the second terminal through SLRRC, SLMACCE, SidelinkControlInformation (SCI). The frequency domain resource subset included in the configured frequency domain resources is determined by the network configuration (LMF or base station) or the second terminal, or the default rule.

[0477] For example, the network device or the second terminal configures the starting position, bandwidth and / or ending position of each frequency domain resource subset;

[0478] Generally, only one of the bandwidth and termination location is required;

[0479] Or the network device or the second terminal configures the starting position and bandwidth or the ending position of the interval frequency domain between every two frequency domain resource subsets.

[0480] Because the starting position of the first frequency domain resource subset is the same as the starting position of the configured frequency domain resource, and the ending position of the first frequency domain resource subset is the starting position of the first interval frequency domain; the starting position of the second frequency domain resource subset is the ending position of the first interval frequency domain, and the ending position of the second frequency domain resource subset is the starting position of the second interval frequency domain, and so on.

[0481] Or default rules or protocol provisions, the protocol stipulates the bandwidth of each resource subset and the bandwidth of the interval frequency domain.

[0482] It should be noted that the resource subsets of the SL-PRS / SL-SRS resources sent by each second terminal are divided in the same manner. The specification may also include different situations.

[0483] 10. The frequency domain resource indication information is indicated by the second terminal (priority), base station or LMF, indicating the frequency domain resource indication information on at least one second terminal. Different second terminals indicate the frequency domain resource indication information corresponding to the SL-PRS / SL-SRS sent by themselves.

[0484] The second terminal indication is indicated through at least one of SLRRC, SLMACCE, and SCI, with SCI being given priority.

[0485] This includes the 1st-stage SCI format transmitted on the PSCCH: SCI format 1-A, used for scheduling PSSCH and the 2nd-stage-SCI on PSSCH; 2nd-stage SCI format SCI format 2-A, 2-B, 2-C. Or other new DCI formats.

[0486] The TRP indication is a base station indication, including at least one of RRC, MACCE and DCI; the DCI includes DCI for sidelink resource scheduling.

[0487] LMF indication is the transmission of indication information through the LPP protocol.

[0488] 11. Specific design of frequency domain resource indication information:

[0489] Different frequency domain resource subsets correspond to different bits. If the bit value is 1, it indicates that the frequency domain resource subset is available, otherwise it indicates that the frequency domain resource subset is not available. Or the other way around is also possible.

[0490] Or different codepoints correspond to different frequency domain resource subsets. The advantage of this method is that if only multiple consecutive frequency domain resource subsets are supported, the number of bits required is less than the number of bits corresponding to 1 bit for each frequency domain resource subset. Therefore, some restrictions are imposed on the multiple frequency domain resource subsets indicated by the frequency domain resource indication information: contiguous frequency domain resource subsets are preferred, but non-contiguous frequency domain resource subsets are not excluded.

[0491] 12. The configuration information of the positioning reference signal includes at least one of the following information:

[0492] Time domain parameters; period; starting time slot; starting symbol position; number of occupied symbols; number of repetitions, interval between repetitions; frequency domain parameters; frequency domain position (freqDomainPosition); frequency domain offset (freqDomainShift); frequency hopping (freqHopping); comb parameters include at least one of the following: comb value (combOffset), cyclic shift (cyclicShift); P0 and alpha, pathlossRS are all power control related parameters; QCLinformation, spatialrelationinformation; reference signal resource ID, reference signal resource setID.

[0493] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0494] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD).
