The embodiments of the present disclosure described below may be applied to the communication system 100 shown in fig. 1, or a part of the main body, but are not limited thereto. The respective bodies shown in fig. 1 are examples, and the communication system may include all or part of the bodies in fig. 1, or may include other bodies than fig. 1, and the number and form of the respective bodies are arbitrary, and the connection relationship between the respective bodies is examples, and the respective bodies may be not connected or may be connected, and the connection may be arbitrary, direct connection or indirect connection, or wired connection or wireless connection.

Wherein the unlicensed spectrum (unlicensed spectrum) and the shared spectrum (shared spectrum) may be interchanged. Optionally, on the unlicensed spectrum, the transmitting end needs to listen before talk (listen before talk, LBT) before transmitting the positioning reference signal on the spectrum resource corresponding to the positioning reference signal to monitor the channel condition of the unlicensed spectrum, optionally, the transmitting end needs to monitor energy (energy) on the unlicensed spectrum first, if the energy intensity is lower than the threshold value, it is indicated that the channel of the unlicensed spectrum is not occupied by other devices, that is, the channel indicating the unlicensed spectrum is in idle state, LBT is successful, and at this time, the transmitting end will transmit the positioning reference signal. If the energy intensity is higher than the threshold value, the channel of the unlicensed spectrum is occupied by other devices, that is, the channel of the unlicensed spectrum is busy, and LBT fails, at this time, the transmitting end cannot transmit the positioning purpose reference signal by using the unlicensed spectrum. Wherein LBT may be interchanged with channel access procedures.

However, in some embodiments, the bandwidth of the LBT detection units is limited by a maximum value, for example, the maximum value is 20 megahertz (MHz), and the bandwidth of the spectrum resources configured for the positioning reference signal for transmission may be greater than the maximum value, where the transmitting end may independently perform LBT detection at each detection unit, for example, the positioning reference signal corresponds to 60MHz of spectrum resources, and the transmitting end may independently perform LBT detection at the first 20MHz, the middle 20MHz, and the last 20MHz of the spectrum resources, and the resulting 20MHz detects LBT idle, and the LBT busy is detected, where how the transmitting end performs the indication of the spectrum resources occupied by the final transmission (i.e., how to indicate to the receiving end the one or more 20MHz spectrum resources occupied by the final transmission of the positioning reference signal, so that the receiving end indicates to receive the positioning reference signal on the corresponding spectrum resources) is a problem to be solved.

Fig. 2A is an interactive schematic diagram illustrating a resource determination method according to an embodiment of the present disclosure. As shown in fig. 2A, embodiments of the present disclosure relate to a resource determination method for a communication system 100, the method including:

in step 2101, the terminal determines a spectrum resource corresponding to the reference signal.

Alternatively, in some embodiments, the spectrum resource may be a shared spectrum (shared spectrum) resource, wherein the shared spectrum may be replaced with an unlicensed spectrum (unlicensed spectrum).

Optionally, the spectrum resource corresponding to the reference signal may be a resource for transmitting the reference signal, optionally, the reference signal transmitting end may perform LBT detection in the spectrum resource, and for a resource in which LBT detection is successful in the spectrum resource, the reference signal may be transmitted on the resource.

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

Optionally, in some embodiments, when the first configuration information, the second configuration information, or the third configuration information is sent by the core network device, the first configuration information, the second configuration information, or the third configuration information may be sent by a long term evolution positioning protocol (Long Term Evolution positioning protocol, LPP) message, and for example, the first configuration information, the second configuration information, or the third configuration information may be carried by the LPP message; when the first configuration information, the second configuration information, or the third configuration information is transmitted by the access network device, the first configuration information, the second configuration information, or the third configuration information may be transmitted by at least one of radio resource control (Radio Resource Control, RRC) signaling, medium access control unit (Medium Access Control Control Element, MAC CE) signaling, and downlink control information (Downlink Control Information, DCI) signaling; when the first configuration information, the second configuration information, or the third configuration information is transmitted by the peer terminal, the PRU, the first configuration information, the second configuration information, or the third configuration information may be transmitted by at least one of SL RRC, SL MAC CE, SL control information (Sidelink Control Information, SCI), physical Sidelink Shared Channel (PSSCH), and Physical Sidelink Control Channel (PSCCH).

Optionally, in some embodiments, the first configuration information, the second configuration information, or the third configuration information is further used to configure at least one of: time domain parameters of the reference signal; frequency domain parameters of the reference signal; comb parameters of the reference signal; a power control parameter 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; resource set ID of reference signal.

Optionally, in some embodiments, the time domain parameter may include at least one of: a period; a starting time slot; a start symbol; number of symbols occupied; repeating the transmission times; the interval value between repeated transmissions.

Optionally, in some embodiments, the spectrum resources corresponding to different reference signals configured by the configuration information (i.e., the aforementioned first configuration information, second configuration information, or third configuration information) are the same or different. For PRSs, for example, the spectrum resources corresponding to different PRS resource sets in the configuration information may be the same or different. Since PRSs are transmitted by access network devices TRP, one 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. 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 to different access network devices by the terminal, the frequency spectrum resources configured in the configuration information can be the same or different for the SRSs communicated between the terminal and the different access network devices; alternatively, for SL SRS or SL PRS, which are transmitted by the terminal to the peer terminal or PRU, the spectrum resources configured in the configuration information may be the same or different for SL SRS or SL PRS in which the terminal communicates with different peer terminals or different PRUs.

Alternatively, in some embodiments, reference signals corresponding to different TRPs may be distinguished using different reference signal identifications. By way of example, PRSs transmitted between different access network devices and terminals may be distinguished by different PRS IDs.

Optionally, the spectrum resource is divided into at least one resource subset, and the at least one resource subset is used for LBT detection of each resource subset by the reference signal transmitting terminal, and for the resource subset with successful LBT detection in the spectrum resource, the reference signal transmitting terminal can transmit the reference signal on the resource subset.

Optionally, in some embodiments, the method for determining at least one resource subset included in the spectrum resource by the terminal may include:

Optionally, when the fourth information includes a start position of an interval resource between two adjacent resource subsets and an end position of an interval resource between two adjacent resource subsets, at least one resource subset included in the spectrum resource may be determined in the following manner: optionally, the starting position of the first subset of resources is the same as the starting position of the spectrum resources, and the ending position of the first subset of resources is the starting position of the first interval frequency domain (i.e. the interval resources between the first subset of resources and the second subset of resources); the starting position of the second resource subset is the ending position of the first interval frequency domain, 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, the starting position and the ending position of each resource subset are determined.

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

the reference signal is SL PRS, and fourth information is determined based on at least one of a transmission of a core network device, a transmission of an access network device, a transmission of a peer terminal, a transmission of a PRU, a protocol convention, and a default rule.

Optionally, in some embodiments, the division manners of the resource subsets in the spectrum resources corresponding to different reference signals are the same or different. For example, for PRS, it is sent to the terminal by the access network device, where the division manner of the resource subsets in the spectrum resources corresponding to PRS communicated between different access network devices and the terminal may be the same or different; or for the SRS, the SRS is sent to the access network device by the terminal, where the division manner of the resource subsets in the spectrum resources corresponding to the SRS communicated between the terminal and different access network devices may be the same or different; or, for the SL SRS or SL PRS, the SL SRS or SL PRS is sent by a terminal to a peer terminal or PRU, where the division manner of the resource subsets in the spectrum resources corresponding to the SL SRS or SL PRS for the terminal to communicate with different peer terminals or different PRUs may be the same or different.

Optionally, in some embodiments, the first information may include a bit map, where each bit in the bit map corresponds to a subset of resources, and a bit value carried by the bit in the bit map is used to indicate whether the subset of resources corresponding to the bit is the first subset of resources.

The downlink channel may include at least one of a physical downlink shared channel (physical downlink shared channel, PDSCH), a physical downlink control channel (physical downlink control channel, PDCCH). For example, the resources occupied by the downlink channel and/or other downlink reference signals are the first set of resources, and then the subset of resources occupied by the PRS (i.e., the aforementioned first subset of resources) is less than or equal to the first set of resources.

Optionally, in other embodiments, the first information may further include: first information corresponding to a current serving cell and/or first information corresponding to a neighboring cell; the method comprises the steps that first information corresponding to a current service cell is used for determining resources occupied by PRS of the current service cell; the first information corresponding to the neighbor cell is used for determining resources occupied by PRSs of the neighbor cell.

Or the first information corresponding to the neighbor cell may be that the neighbor cell (such as the access network device of the neighbor cell) sends the first information corresponding to the neighbor cell to the core network device, and then the core network device sends the first information corresponding to the neighbor cell to the first device corresponding to the current serving cell.

Optionally, in some embodiments, the uplink reference signal may be an SRS, the second information may be used to determine resources occupied by the uplink reference signal, and, by way of example, the resources determined by the second information may be a first subset of resources in the spectrum resources, where the first subset of resources may be a subset of resources occupied by the uplink reference signal when transmitted; wherein the resource determined by the second information is a shared spectrum resource. Alternatively, the terminal may send the second information to the first device. Optionally, the first device may include at least one of: core network equipment; an access network device.

Optionally, in some embodiments, since the uplink reference signal is sent by the terminal to the access network device, the second information is determined by the terminal (i.e. the sending end of the reference signal), and should be finally sent to the access network device (i.e. the receiving end of the reference signal), so that the access network device can successfully receive the uplink reference signal based on the second information, to achieve successful transmission of the uplink reference signal. Optionally, in some embodiments, optionally, the terminal may first perform LBT detection on the spectrum resource, and the resource indicated by the second information may be part or all of the resources where the LBT detection of the terminal is successful, after the terminal determines the second information, the terminal may directly send the second information to the access network device, or the terminal may send the second information to the core network device, and then the core network device forwards the second information to the access network device.

Alternatively, in some embodiments, when the terminal transmits the second information to the access network device, the second information may be transmitted based on Uplink control information (Uplink Control Information, UCI) or Uplink (UL) mac ce, and when the terminal transmits the second information to the core network device, the second information may be transmitted based on LPP message.

Optionally, in some embodiments, the second information may include a bit map, where each bit in the bit map corresponds to a subset of resources, and a bit value carried by the bit in the bit map is used to indicate whether the subset of resources corresponding to the bit is the first subset of resources. For example, when the bit value carried by the bit is a first value (e.g., 1), the resource subset corresponding to the bit is indicated to be the first resource subset, and when the bit value carried by the bit is a second value (e.g., 0), the resource subset corresponding to the bit is indicated to be not the first resource subset.

Optionally, in other embodiments, the second information may include at least one indicator code; the different indication codes respectively correspond to at least one resource subset, alternatively, the indication codes may correspond to at least one continuous resource subset, the indication codes may correspond to at least one discontinuous resource subset, and the indication codes included in the second information are indication codes corresponding to the first resource subset. Alternatively, the indication code may be a code point (codepoint).

Optionally, in some embodiments, the second information may include any channel and/or other reference signals in addition to the reference signal; alternatively, the resources occupied by the channel and/or other reference signal may be used to determine a first subset of resources, alternatively, the first subset of resources may be included in the resources occupied by the channel and/or other reference signal, or the resources occupied by the channel and/or other reference signal included in the second information may be equal to the resources occupied by the uplink reference signal. Optionally, the second information may include at least one of any uplink channel and any other uplink reference signal except for SRS for positioning. The uplink channel may include at least one of a physical uplink shared channel (physical uplink shared channel, PUSCH), a physical uplink control channel (physical uplink control channel, PUCCH). For example, the resources occupied by the uplink channel and/or other uplink reference signals are the second set of resources, and then the subset of resources occupied by the SRS for positioning (i.e., the aforementioned first subset of resources) is less than or equal to the second set of resources.

The following is an exemplary description of the above method.

If the positioning use reference signal is PRS:

1. the terminal receives frequency domain resource indication information of PRS sent by the network equipment, and the information is used for indicating which frequency domain resource subsets in the configured frequency domain resources are occupied by the PRS.

The configured frequency domain resources are determined based on PRS configuration information sent by the LMF through the LPP, and a subset of the frequency domain resources comprised by the configured frequency domain resources are determined by a network configuration (LMF or base station), or a default rule.

Such as the network configuring the starting location, bandwidth and/or ending location of each subset of frequency domain resources; the bandwidth and the termination position generally need one;

or the network device configures a start position and a bandwidth or end position of the spaced frequency domain in between each two subsets of frequency domain resources. 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; and the starting position of the second subset of frequency domain resources is the ending position of the first spaced frequency domain, the ending position of the second subset of frequency domain resources is the starting position of the second spaced frequency domain, and so on.

Or default rules or protocols, the protocol specifying the bandwidth of each subset of resources, and the bandwidth of the spaced frequency domain.

It should be noted that: the subset of resources that prioritize PRS resources for each TRP is the same way to divide. The description may also contain different situations.

2. The frequency domain resource indication information is indicated by TRP (priority DCI) or LMF, and indicates the frequency domain resource indication information on at least one TRP

The TRP indication is a base station indication and comprises at least one of RRC, MACCE and DCI; the priority DCI, DCI includes groupcommon DCI and uespecdci.

The LMF indication is the transmission of indication information via the LPP protocol.

3. The frequency domain resource indication information is specifically designed:

different frequency domain resource subsets correspond to different bits, if the bit value is 1, the frequency domain resource subset available is indicated, otherwise, the novaiable is indicated; or vice versa.

Or a combination of different codepoints corresponding to different subsets of frequency domain resources, the advantage of this approach is that: if only a plurality of frequency domain resource subsets are supported continuously, the number of bits required is less than the number of bits corresponding to 1bit for each frequency domain resource subset. Some restrictions are given on the plurality of frequency domain resource subsets indicated by the frequency domain resource indication information: preferably, the plurality of frequency domain resource subsets are contiguous, nor are non-contiguous.

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

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 neighbor cell; if the indication is LMF indication, the LMF indicates frequency domain resource indication information of TRPs corresponding to the serving cell and the neighbor cell.

PRS resources corresponding to different TRPs are distinguished by different prssids.

If the positioning use reference signal is SRS:

5. the terminal sends frequency domain resource indication information corresponding to the SRS, which is used for indicating which frequency domain resource subsets in the configured frequency domain resources are occupied by the SRS

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

Such as the network configuring the starting location, bandwidth and/or ending location of each subset of frequency domain resources;

the bandwidth and the termination position generally need one;

or the network device configures a start position and a bandwidth or end position of the spaced frequency domain in between each two subsets of frequency domain resources.

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; and the starting position of the second subset of frequency domain resources is the ending position of the first spaced frequency domain, the ending position of the second subset of frequency domain resources is the starting position of the second spaced frequency domain, and so on.

It should be noted that: the resource subset division manner of the SRS sent to different TRPs is the same, the SRS sent to different TRPs is contained in one SRS resource set, or the beam directions corresponding to the SRS sent to different TRPs are different.

6. The frequency domain resource indication information is sent to the gNB (priority UCI) or the LMF, and if the SRS transmission is based on the beams, the frequency domain resource indication information on at least one beam is indicated.

Based on at least one of UCI, MACCE and RRC if sent to the gNB; the UCI is prioritized, the PUCCH is prioritized based, and PUSCH is not excluded.

Sent to LMF, then based on LPP protocol.

7. The frequency domain resource indication information is specifically designed:

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

If the positioning use reference signal is slpls or SLSRS:

9. the first terminal (may be a general terminal or PRU) receives frequency domain resource indication information of the SL-PRS/SL-SRS sent by at least one second terminal (may be a general terminal or PRU) for indicating which frequency domain resource subsets of the configured frequency domain resources the SL-PRS/SL-SRS occupies.

The configured frequency domain resources are determined based on PRS configuration information transmitted 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). And the subset of frequency domain resources comprised by the configured frequency domain resources is determined by the network configuration (LMF or base station) or the second terminal, or a default rule.

Such as the network device or the second terminal configuring the starting location, bandwidth and/or ending location of each subset of frequency domain resources;

the bandwidth and the termination position generally need one;

or the network device or the second terminal configures a start position and a bandwidth or an end position of the interval frequency domain in between every two frequency domain resource subsets.

It should be noted that: the resource subsets of the SL-PRS/SL-SRS resources transmitted by the second terminals are preferentially divided in the same way. The description may also contain different situations.

10. The frequency domain resource indication information is indicated by a second terminal (priority), a base station or an LMF, and indicates the frequency domain resource indication information on at least one second terminal, and different second terminals indicate the frequency domain resource indication information corresponding to the SL-PRS/SL-SRS sent by the second terminal.

The second terminal indication is indicated by at least one of SLRRC, SLMACCE, SCI, prioritizing SCI.

The method comprises the steps of 1st-stage SCI format transmitted on PSCCH: SCIFormat 1-A for scheduling PSSCH and 2nd-stage-SCI on PSSCH;2nd-stage SCI format SCIformat 2-A,2-B,2-C. Or other new dcifeormats.

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