It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0042] For ease of understanding, the antenna reference point (ARP) mentioned later in the embodiments of the present application is briefly introduced here. Figure 1b , assuming that the terminal is a car, and the front and rear panels of the car participate in data transmission to achieve communication functions such as terminal positioning, channel detection or channel estimation. Then, compared with a single antenna panel, in order to further improve positioning accuracy, data transmission rate and reliability, etc., related technologies introduce the concept of ARP in SL positioning, that is, through ARP Figure 1b An antenna panel location of the vehicle is shown. Accordingly, the ARP ID is used to uniquely identify an ARP of a terminal.

[0043] Based on this, the technical solution provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings and through some embodiments and their application scenarios.

[0044] like Figure 2 As shown, it is a flow chart of a communication method 200 provided by an exemplary embodiment of the present application, and the method 200 can be, but is not limited to, executed by a first terminal, and can be specifically executed by hardware and / or software installed in the first terminal. In this embodiment, the method 200 can at least include the following steps.

[0045] S210: The first terminal obtains an association relationship between a reference signal resource and a target object.

[0046] Among them, the first terminal can be a SL terminal in SL transmission, or a terminal in an uplink (Uplink), etc. Correspondingly, when the first terminal is a SL terminal in SL transmission, the reference signal resources can be but are not limited to SL reference signal resources, such as positioning reference signal (Positioning Reference Signal, PRS) resources on SL, channel state information reference signal (Channel State Information Reference Signal, CSI RS) resources or other reference signal resources related to FR2 beams, etc., and are not limited here.

[0047] Alternatively, when the first terminal is a terminal in UL transmission and communicates based on the UL, the reference signal resource may be, but is not limited to, a sounding reference signal (Sounding Reference Signal, SRS) resource on the UL, etc.

[0048] The target object associated with the reference signal resource may be one or more of ARP, beam, spatial filter, or timing error group, etc., which are not limited here. The timing error group is an error group formed according to the time error between different transmissions. In this embodiment, the timing error group may include but is not limited to at least one of a transmission time error group (Tx Time Error Group, TxTEG) and a reception transmission time error group (RxTx TEG).

[0049] Based on this, in this embodiment, the association relationship between the reference signal resource and the target object may include different target objects being associated with (or corresponding to) different reference signal resources, or different target objects being associated with (or corresponding to) different reference signal sequences in the same reference signal resource. Thus, on the one hand, by defining the association relationship between the target object and the reference signal resource, the first terminal can use the correct target object (such as beam, ARP, or time error group) when sending the first reference signal to ensure the transmission reliability of the first reference signal; on the other hand, when there are multiple target objects, the first reference signal can be sent based on the association relationship between the target object and the reference signal resource, and the transmission rate of the first reference signal can be improved.

[0050] For example, taking the target object as ARP, a first terminal can support the transmission of multiple ARP data (such as the first reference signal), and then perform SL positioning, channel detection or channel estimation based on multiple ARP sending data, which can not only increase the data transmission rate, but also improve the accuracy of data transmission.

[0051] In one implementation, for the aforementioned situation where different target objects are associated with different SL reference signal resources, the different SL reference signal resources can be located in the same time unit (such as time slot, symbol, frame, etc.), or in different time units, and there is no limitation here.

[0052] It is understandable that if the SL reference signal resources are located in different time units, then the reference signal resources associated with the multiple target objects can be distinguished by the reference signal resources corresponding to the different time units. For example, assuming that the time unit is a slot, then within a slot, the first terminal can select or reserve a reference signal resource to associate with one target object.

[0053] If the SL reference signal resources are located in the same time unit, then the reference signal resources associated with the multiple target objects can be distinguished by different reference signal resources in a time unit. For example, in a slot, the first terminal selects or reserves multiple reference signal resources, and they are associated with multiple target objects, such as one reference signal resource is associated with one target object or one reference signal resource is associated with multiple target objects, etc., which is not limited here.

[0054] Optionally, for the case where the SL reference signal resources are located in the same time unit, the reference signal resources used to distinguish different target objects within a time unit may be reference signal resources of comb-based frequency division multiplexing (FDM); or, the reference signal resources used to distinguish different target objects within a time unit (such as a slot) may be reference signal resources of time division multiplexing (TDM) occupying different sub-time units (such as a symbol).

[0055] In addition, for the aforementioned situation where different target objects are associated with different reference signal resources, if the reference signal resource is an SL reference signal resource and the first terminal is configured with a shared resource pool and a dedicated resource pool, then the shared resource pool and the dedicated resource pool may have different designs. It can be understood that the aforementioned shared resource pool is a resource pool shared for reference signal (such as SL reference signal, UL reference signal, etc.) transmission and data (or physical sidelink shared channel (PSSCH)) transmission. The dedicated resource pool is a resource pool dedicated to reference signal (such as SL reference signal, UL reference signal, etc.) resource transmission.

[0056] For example, for a shared resource pool, it can support different target objects being associated with different reference signal resources, and different SL reference signal resources can be located in the same time unit or in different time units. However, for a dedicated resource pool, it supports different target objects being associated with different reference signal resources in different time units. Therefore, through the aforementioned restrictions, on the basis of realizing resource pool multiplexing, the first terminal can obtain multiple different SL reference signal resources to realize the transmission of the first reference signal, thereby improving resource utilization.

[0057] For another example, the shared resource pool may not support comb-based FDM of reference signals of different terminals, but there may be enough comb-based FDM for a single terminal to choose from. The dedicated resource pool supports comb-based FDM of reference signal resources of different terminals, and needs to support one-to-one mapping between physical sidelink control channel (PSCCH) and reference signal resources, and may not be able to support comb-based FDM of a single terminal.

[0058] Based on this, in this embodiment, the relevant information about which configuration the shared resource pool and the dedicated resource pool actually support (such as whether different target objects are associated with different reference signal resources, and whether different SL reference signal resources are located in the same time unit, etc.) can be included in the configuration information of the resource pool. For example, if the configuration information included in the resource pool configuration information of a resource pool (such as a shared resource pool or a dedicated resource pool) indicates that 'reference signal resources corresponding to multiple target objects are distinguished by reference signal resources in different time units (such as slots)', then different target objects in the resource pool can be distinguished by reference signal resources located in different slots.

[0059] In the case where different target objects are associated with different reference signal sequences in the same reference signal resource, it can be understood that the reference signal resources corresponding to the multiple target objects are distinguished by different reference signal sequences. For example, in this embodiment, the correspondence between different target objects and different reference signal sequences may include but is not limited to at least one of the following (11)-(14).

[0060] (11) There is an association relationship between the target object identifier (ID) and the reference signal sequence (sequence) ID, such as target object 0 is associated with reference signal sequence 0, target object 1 is associated with reference signal sequence 1, and so on.

[0061] The reference signal sequence ID is used to generate an initial value (cinit) of the reference signal sequence, such as some bits (bits) in the initial value of the reference signal sequence are generated by the reference signal sequence ID, or some bits (bits) in the initial value of the reference signal sequence are equal to the reference signal sequence ID, etc., and no limitation is made here.

[0062] The cinit is used to generate a reference signal sequence.

[0063] It is worth noting that in the context of this application, for the target object ID, when the target object is ARP, the target object ID is ARP ID (such as Tx ARP ID); when the target object is beam, the target object ID is beam ID (or spatialrelation ID, SL PRS resource set ID, SL PRS ID, etc.); when the target object is TEG, the target object ID is TEG ID (such as Tx TEG ID, or RxTx TEG ID), etc.

[0064] (12) There is an association relationship between the target object ID and the initial value of the reference signal sequence.

[0065] The cinit is used to generate the reference signal sequence.

[0066] (13) The target object ID is associated with a cyclic shift of the reference signal sequence.

[0067] For example, the target object ID 0 is associated with cyclic shift 0, the target object ID 1 is associated with cyclic shift 1, and so on.

[0068] It can be understood that, assuming that the reference signal sequence is x(n), then after adding the cyclic shift, it is e(j*alpha*n)*x(n), alpha is the phase introduced by the cyclic shift value, for example, alpha=2pi*cs_n / csmax, cs_n is the cyclic shift value of the nth target object, and csmax is the maximum number of cyclic shifts.

[0069] (14) The target object ID is associated with an orthogonal cover code (OCC) of the reference signal sequence.

[0070] The OCC code may be a frequency domain OCC code or a time domain OCC code, which is not limited here.

[0071] Through the different association methods provided in the aforementioned (11)-(14), such as the target object ID can be associated with the reference signal sequence ID or the cyclic shift of the reference signal sequence or the OCC code of the reference signal sequence, the flexibility of configuring the association relationship between the target object and the reference signal sequence in the reference signal resource can be improved to be suitable for the configuration of the association relationship in different communication scenarios.

[0072] It can be understood that the association relationship between the aforementioned target object ID and the reference signal sequence (such as the ID, initial value, cyclic shift, OCC code of the reference signal sequence) can be achieved by protocol agreement or pre-definition or network configuration or terminal configuration, and is not limited here.

[0073] S220: Send a first reference signal based on the association relationship between the reference signal resource and the target object.

[0074] For example, when the target object is an ARP, a first reference signal is sent based on one or more ARPs associated with the reference signal resource; and when the target object is a beam, a first reference signal is sent based on one or more beams associated with the reference signal resource to improve the transmission reliability of the reference signal.

[0075] In this embodiment, the first terminal obtains the association relationship between the reference signal resource and the target object, and sends the first reference signal based on the association relationship between the reference signal resource and the target object, wherein the target object includes an antenna reference point, a beam or a time error group, and the association relationship between the reference signal resource and the target object includes different target objects being associated with different reference signal resources, or different target objects being associated with different reference signal sequences in the same reference signal resource. Thus, on the one hand, by defining the association relationship between the target object and the reference signal resource, the first terminal can use the correct target object (such as a beam, ARP, or time error group) when sending the first reference signal to ensure the sending reliability and communication quality of the first reference signal; on the other hand, when there are multiple target objects, sending the first reference signal based on the association relationship between the target object and the reference signal resource can also improve the transmission rate of the first reference signal.

[0076] like Figure 3 As shown, it is a flow chart of a communication method 300 provided by an exemplary embodiment of the present application, and the method 300 can be, but is not limited to, executed by a first terminal, and can be specifically executed by hardware and / or software installed in the first terminal. In this embodiment, the method 300 can at least include the following steps.

[0077] S310: The first terminal obtains an association relationship between a reference signal resource and a target object.

[0078] S320: Send a first reference signal based on the association relationship between the reference signal resource and the target object.

[0079] The target object includes an antenna reference point, a beam or a time error group, and the association relationship between the reference signal resource and the target object includes different target objects being associated with different reference signal resources, or different target objects being associated with different reference signal sequences in the same reference signal resource.

[0080] It can be understood that, in addition to referring to the relevant description in the aforementioned method embodiment 200, in a possible implementation method, the association relationship between the reference signal resource and the target object mentioned in this application can be obtained (or determined) in a variety of ways. For example, it can be determined autonomously by the first terminal, or by agreement, or by the first terminal based on target scheduling information (such as network scheduling information or scheduling information of other terminals (such as receiving terminals, target terminals (target UE), anchor terminals (anchor UE)), or scheduling information of location servers, etc.), thereby improving the flexibility of the configuration and scheduling of the association relationship, and adapting to the configuration of the association relationship in different communication scenarios.

[0081] For example, when the association relationship between the reference signal resource and the target object is determined by the first terminal according to the target scheduling information, the target scheduling information may include but is not limited to at least one of the reference signal resource, the number of the target objects, and the association relationship between the reference signal resource and the target object.

[0082] Exemplarily, for the aforementioned information that may be included in the target scheduling information, the process by which the first terminal determines the association relationship between the reference signal resource and the target object based on the target scheduling information may include at least one of the following (21)-(23).

[0083] (21) When the target scheduling information includes the reference signal resource, the first terminal autonomously determines an association relationship between the reference signal resource and the target object based on the reference signal resource included in the target scheduling information.

[0084] That is to say, the target scheduling information indicates (or configures) the reference signal resources involved in the association relationship, but does not indicate (or configure) the number of target objects involved in the association relationship, the identifiers of the target objects, and how many target objects are associated with one reference signal resource, etc. In this case, when determining the association relationship, the first terminal can independently determine the aforementioned information not indicated (configured) in the target scheduling information according to its own needs, protocol agreements, etc., and then determine the association relationship in combination with the reference signal resources included in the target scheduling information. Thus, the scheduling of the association relationship is realized by indicating the reference signal resources in the target scheduling information, which can not only ensure the acquisition of the association relationship by the first terminal, but also save signaling overhead.

[0085] (22) When the target scheduling information includes the reference signal resource and the number of target objects, the first terminal autonomously determines the association relationship between the reference signal resource and the target object based on the reference signal resource and the number of target objects included in the target scheduling information.

[0086] That is to say, the target scheduling information indicates (or configures) the reference signal resources and the number of target objects involved in the association relationship, but does not indicate (or configure) the identifiers of the target objects involved in the association relationship, and how many target objects are associated with one reference signal resource, etc. In this case, when determining the association relationship, the first terminal can independently determine the aforementioned information not indicated (configured) in the target scheduling information according to its own needs, protocol agreements, etc., and then determine the association relationship in combination with the reference signal resources and the number of target objects included in the target scheduling information. Thus, the scheduling of the association relationship is realized by indicating the reference signal resources and the number of target objects in the target scheduling information, which can not only ensure the acquisition of the association relationship by the first terminal, but also save signaling overhead.

[0087] (23) The target scheduling information includes an association relationship between the reference signal resource and the target object, and the first terminal determines the association relationship between the reference signal resource and the target object according to the target scheduling information, thereby ensuring consistency in the understanding of the association relationship between the first terminal and the target scheduling information sending end. The association relationship between the reference signal resource and the target object included in the target scheduling information in (23) may be, but is not limited to, an association relationship dedicated to the first terminal.

[0088] It can be understood that the manner in which the first terminal determines the association relationship based on the target scheduling information may include but is not limited to the manner described in (21)-(23) above.

[0089] S330: The first terminal sends a first signaling.

[0090] The first signaling is used to indicate to the first device the association relationship between the target object and the reference signal resource, so that the first device can select resources, perform SL positioning, distinguish or determine positioning results, estimate or distinguish positions, etc. In this embodiment, the execution of S330 may be located after S310 or S320, or before S310 or S320, which is not limited here.

[0091] Optionally, the first device can be a receiving terminal (Rx UE), a service terminal (Server UE), an anchor terminal (Anchor UE), a target terminal (target UE), etc. on the SL, or it can be a network side device, a location management function (Location Management Function, LMF), a core network device, etc. on the UL, and there is no limitation here.

[0092] For example, for the Rx UE, if the measurement result of the SL reference signal needs to be determined by the SL reference signal resources of multiple time units (such as slots), the association relationship between the SL reference signal resources and the target object ID needs to be indicated to the Rx UE, so that the Rx UE can clearly understand the association relationship between the SL reference signal resources and the target object ID, so as to avoid the Rx UE jointly processing the measurement results corresponding to different transmitting target objects (Tx target objects), affecting the accuracy of the processing results.

[0093] For another example, for LMF, server UE, LMF or core network equipment, by indicating the association relationship between SL reference signal resources and target object ID to LMF, server UE, LMF or core network equipment, LMF, server UE, LMF or core network equipment can clearly know which target object the measurement result corresponds to, thereby assisting LMF, server UE, LMF or core network equipment to perform position solution, channel estimation or channel detection according to different target object IDs, thereby ensuring the accuracy of the processing results.

[0094] In this case, considering the different receiving objects corresponding to the first signaling, the first signaling may be SL signaling or Uu port signaling (or UL message). For SL signaling, the first signaling may be sidelink control information (Sidelink Control Information, SCI), SL high-level message (such as SL radio resource control (Radio Resource Control, RRC), SL-Media Access Control Control Element (Medium Access Control Control Element, MAC CE)), etc.

[0095] For the signaling of the Uu port, the first signaling can be an uplink control message (Uplink Control Information, UCI) (or physical uplink control channel (Physical Uplink Control Channel, PUCCH)), MAC CE, RRC message or LTE Positioning Protocol (LTE Positioning Protocol, LPP), etc., and is not limited here.

[0096] Based on this, the first signaling in different communication scenarios is explained below in combination with different implementation methods.

[0097] Implementation 1

[0098] Assuming that the reference signal resource is an SL reference signal resource and the first signaling is an SCI, then, depending on the different association methods between the target object and the reference signal resource, the SCI may include or indicate different information.

[0099] For example, if the different target objects are associated with different SL reference signal resources in different time units, the SCI may include or indicate at least one of the following (31)-(32).

[0100] (31) An association relationship between a first resource and a target object ID, wherein the first resource is an SL reference signal resource in the time unit where the SCI is located. Thus, by indicating the association relationship between the first resource and the target object ID, the first device (such as a receiving end UE) can determine that reference signals in different slots belong to the same target object or different target objects, thereby distinguishing measurement results of the same or different target objects.

[0101] (32) An association relationship between a second resource and a target object ID, wherein the second resource is a reserved (or selected) SL reference signal resource in a reserved time unit. Thus, by indicating the association relationship between the second resource and the target object ID, the first device (such as a receiving UE) can determine the association relationship between the reference signal resource of a future reserved time unit (such as a slot) and the target object, thereby obtaining the association relationship between all target objects and the reference signal resources earlier, and preparing for receiving processing and / or resource exclusion earlier, so as to improve data processing efficiency. For example, in the case where the target object is a beam, the receiving end can obtain the transmit beam information of the reserved SL reference signal resource in advance, and thereby prepare in advance the receive beam for matching the reserved SL reference signal resource.

[0102] For another example, if the different target objects are associated with different SL reference signal resources in the same time unit, the SCI includes or indicates at least one of the following (41)-(42).

[0103] (41) relevant information of a third resource, and an association relationship between the third resource and a target object ID, wherein the third resource is an SL reference signal resource in the time unit where the SCI is located. Thus, by indicating the relevant information of the third resource, and the association relationship between the third resource and the target object ID, the first device (such as a receiving end UE) can determine that the reference signals in the same time unit (such as a slot) belong to the same target object or different target objects, thereby distinguishing the measurement results of the same or different target objects.

[0104] Optionally, the relevant information of the third resource includes at least one of the following (411)-(414).

[0105] (411) Identification of SL reference signal resource.

[0106] (412) Resource element offset (RE offset) of the SL reference signal resource.

[0107] (413) The starting symbol position of the SL reference signal resource.

[0108] (414) Duration of the SL reference signal resource.

[0109] It is worth noting that, within a time unit (such as a slot), the number of the third resources is not less than 2.

[0110] Exemplarily, assuming that the time unit is a slot, the SCI may indicate N reference signal resource IDs in the slot where the current SCI is located (or N RE offsets, or a combination of the starting symbol position or symbol duration of N reference signal resources, or one or more of the starting symbol position, symbol duration (symbol duration), RE offset, and target object ID associated with each reference signal resource of the N reference signal resources.

[0111] Or, the SCI indicates N reference signal resource IDs (or N RE offsets . . . ) in each of the multiple reserved slots and a target object ID associated with each reference signal resource.

[0112] It can be understood that “N” is the number of reference signal resources selected or reserved for one slot, or the total number of target objects associated with the reference signal resources, or the number of target objects corresponding to one slot.

[0113] (42) Relevant information of a fourth resource, or an association relationship between the fourth resource and a target object ID, wherein the fourth resource is a reserved SL reference signal resource in a reserved time unit. Thus, by indicating relevant information of the fourth resource, or an association relationship between the fourth resource and a target object ID, the receiving end can determine an association relationship between reference signal resources and target objects in future reserved time units (such as slots), thereby obtaining an association relationship between all target objects and reference signal resources earlier, and preparing for receiving processing and / or resource exclusion earlier, so as to improve data processing efficiency.

[0114] Optionally, in one implementation, if the association relationship between the reserved SL reference signal resources and the target object is not indicated when indicating the reserved SL reference signal resources in the reserved time unit, then the association relationship may be indicated in the SCI of the reserved time unit.

[0115] In addition, in a possible implementation, the number of SL reference signal resources (ie, fourth resources) reserved in the reserved time unit in the aforementioned (42) is not less than 2.

[0116] In another implementation, similar to the third resource, the relevant information of the fourth resource may include but is not limited to at least one of the following (421)-(424).

[0117] (421)Identifier of SL reference signal resource.

[0118] (422) Resource unit offset of SL reference signal resource.

[0119] (423) The starting symbol position of the SL reference signal resource.

[0120] (424) Duration of the SL reference signal resource.

[0121] For the related descriptions of (421)-(424), please refer to the related descriptions in the aforementioned (411)-(414). To avoid repetition, they will not be repeated here.

[0122] It is worth noting that, within a time unit (such as a slot), the number of the fourth resources is not less than 2.

[0123] For example, if the different target objects are associated with different reference signal sequences in the same SL reference signal resource, the SCI includes or indicates at least one of the following (51)-(55).

[0124] (51) The association relationship between the cyclic shift of the first reference signal sequence and the target object ID.

[0125] The first reference signal sequence is a reference signal sequence of a SL reference signal resource in a time unit where the SCI is located, or the reference signal sequence is a reference signal sequence in a reserved SL reference signal resource in a reserved time unit.

[0126] (52) An association relationship between the sequence ID of the first reference signal sequence and the target object ID.

[0127] (53) The association relationship between the OCC code of the first reference signal sequence and the target object ID.

[0128] (54) The target object ID.

[0129] Among them, if the SCI only indicates the target object ID, then the first device combines the target object ID indicated by the SCI and the association relationship between the first reference signal sequence and the target object ID implemented by preconfiguration (or predefinition) or protocol agreement (such as the association relationship between the cyclic shift of the first reference signal sequence and the target object ID, the association relationship between the sequence ID of the first reference signal sequence and the target object ID, and the association relationship between the OCC code of the first reference signal sequence and the target object ID) to determine the final association relationship between the target object and the reference signal sequence, and perform relevant processing.

[0130] (55) The number of target objects.

[0131] Among them, similar to (53), if the SCI only indicates the number of target objects, then the first device combines the number of target objects indicated by the SCI and the association relationship between the first reference signal sequence and the target object ID implemented by preconfiguration (or predefinition) or protocol agreement (such as the association relationship between the cyclic shift of the first reference signal sequence and the target object ID, the association relationship between the sequence ID of the first reference signal sequence and the target object ID, and the association relationship between the OCC code of the first reference signal sequence and the target object ID) to determine the final association relationship between the target object and the reference signal sequence, and perform relevant processing.

[0132] It can be understood that by indicating one or more of the aforementioned (51)-(55) through SCI, on the one hand, the flexibility of the indication method can be improved, and on the other hand, it can also enable the first device (such as the receiving end UE) to determine the association between the reference signal sequence in the reference signal resource of the slot where the current SCI is located and the target object to distinguish the measurement results of the same or different target objects, or determine the association between the reference signal sequence in the reference signal resource of the future reserved time unit (such as the slot) and the target object, thereby obtaining the association between all target objects and the reference signal resources earlier, and preparing for receiving processing and / or resource exclusion earlier, so as to improve data processing efficiency.

[0133] It is worth noting that when the association relationship between the reference signal resource and the target object is indicated through the SCI, when the reference signal resource is a periodic resource, the association relationship between the reference signal resources and the target object of different periods is the same, such as the association relationship between the reference signal resource and the target object in period 1 is the same as the association relationship between the reference signal resource and the target object in period 2, etc., thereby limiting the association relationship between the reference signal resources and the target object of different periods to be the same, which can not only maintain the stable sending of reference signal resources in different periods, but also assist the receiving end of the SCI to stably process the reference signal resources of different periods.

[0134] In addition, for the case where the first terminal is configured with a shared resource pool and a dedicated resource pool, if the SL reference signal is located in the dedicated resource pool, then the SCI is a first-level SCI.

[0135] If the SL reference signal is located in a shared resource pool, then the SCI is a first-level SCI or a second-level SCI.

[0136] Implementation 2

[0137] Assuming that the reference signal resource includes a SL reference signal resource or an uplink UL reference signal resource, the first signaling may include the SL high-level message or the UL message. The SL high-level message or the UL message may indicate or include at least one of the following (61)-(62).

[0138] (61) The number of target objects: The number of target objects may be understood as the number of target objects associated with the reference signal resource, or the total number of target objects used to send the first reference signal.

[0139] Optionally, in this scenario, at least one of the association between the cyclic shift of the first reference signal sequence and the target object ID, the association between the sequence ID of the first reference signal sequence and the target object ID, and the association between the OCC code of the first reference signal sequence and the target object ID can be determined based on at least one of (network or terminal) pre-configuration (predefinition) and protocol agreement. After the receiving terminal obtains the indicated number of target objects, it generates the first reference signal sequence for different target objects based on the above-mentioned associations to process the SLPRS.

[0140] Or, optionally, in this scenario, the indication of the association relationship between the reference signal resource and the target object (such as a relatively dynamic association relationship) may be indicated by an SCI.

[0141] (62) The target object ID. The target object ID may be understood as a target object ID associated with the reference signal resource, or a target object ID used to send the first reference signal.

[0142] Optionally, the number of target objects or target object IDs corresponding to each reference signal sent by the first terminal are the same.

[0143] It can be understood that by indicating at least one of the aforementioned (61)-(62) through the SL high-level message or the UL message, the first device (such as LMF, server UE, LMF or core network equipment, etc.) can be further assisted in determining the association relationship between the reference signal resources and the target object, so as to achieve the purpose of position resolution according to different target object IDs, etc., and ensure the accuracy of the processing results.

[0144] In one implementation, for the situation provided in the embodiment of the present application where the association relationship between the reference signal resource and the target object is indicated by the first signaling, each of the reference signal resources may be associated with one or more target objects.

[0145] For example, if each of the reference signal resources is associated with a target object, the association relationship between the reference signal resource and the target object may include an association relationship between the target object ID and the first object. It can be understood that the reference signal resource is used to identify the reference signal resource. For example, in this embodiment, the first object may include but is not limited to at least one of a timestamp of the reference signal resource and a reference signal resource ID. For example, the association relationship includes [time stamp, reference signal resource ID, target object ID].

[0146] Alternatively, if each of the reference signal resources is associated with at least two target objects, the association relationship may include an association relationship between the second object and the third object. It can be understood that the second object is used to identify the reference signal resource, such as the second object may include but is not limited to at least one of the time stamp of the reference signal resource, the reference signal resource ID, the reference signal sequence ID in the reference signal resource, the cyclic shift of the reference signal sequence in the reference signal resource, and the OCC code of the reference signal sequence in the reference signal resource, and the third object is relevant information of the target object, such as the third object includes at least one of the number of target objects, the target object ID associated with the reference signal resource, the target object ID associated with the reference signal sequence ID in the reference signal resource, the target object ID associated with the cyclic shift of the reference signal sequence in the reference signal resource, and the target object ID associated with the OCC code of the reference signal sequence associated with the reference signal resource.

[0147] If the third object includes the number of target objects or the target object ID, the association relationship between the target object ID and the reference signal sequence of the reference signal resource may be preconfigured, predefined or agreed upon by protocol.

[0148] It is worth noting that when at least one of the sequence ID, cyclic shift, and OCC code associated with the target object ID is indicated by the first signaling, it can be considered to indicate the association relationship between the target object ID and the reference signal sequence.

[0149] In another implementation, for the aforementioned first signaling, such as SCI, SL high-level message, and UL message, in order to improve the flexibility of the first signaling indication and reduce network overhead, in this embodiment, the indication method of the first signaling may be but is not limited to including at least one of the following (71)-(73).

[0150] (71) A one-shot indication, where the one-shot indication indicates that the first terminal indicates (or reports) the association relationship between the target object and the reference signal resource to the first device once.

[0151] Optionally, the first terminal may send the SL high-level message or UL message within a predetermined time after receiving the first request according to a pre-configured or protocol-agreed response time to complete the sending of the SL high-level message or UL message (or a response to the first request).

[0152] (72) A periodic indication, where the periodic indication indicates that the first terminal periodically indicates (or reports) the association relationship between the target object and the reference signal resource.

[0153] The first terminal may periodically indicate (or report) the SL high-layer message or UL message according to a preconfigured or agreed period.

[0154] Optionally, when the first terminal indicates the period of the SL high-level message or UL message, the first period can be determined according to the period offset (which can be achieved by protocol agreement, high-level configuration, etc.), or according to the interval between the first period and the first request (the interval can be equal to the period).

[0155] In addition, in one periodic indication (ie, during the interval between two periodic indications), if the relationship between the target object and the reference signal resource changes, the first terminal may indicate the change in the association relationship between the target object and the reference signal resource.

[0156] (73) An event trigger indication, where the event trigger indication indicates that the first terminal indicates (or reports) the association relationship between the target object and the reference signal resource when a specified event is detected.

[0157] The "event" involved in the event triggering indication may be agreed upon by a protocol or indicated by a network. In this embodiment, the "event" may be a change in the association relationship between the target object and the reference signal resource. For example, when the "event" occurs, the first terminal may start a pre-configured or agreed timer and complete the indication (or reporting) of the first signaling before the timer expires.

[0158] In addition, in one implementation, the event-triggered indication may be combined with a one-time indication, that is, the first terminal may first indicate the association relationship between the target object and the reference signal resource once, and then indicate the change information of the association relationship between the target object and the reference signal resource according to the event triggering method.

[0159] For the indication method of the aforementioned first signaling, it can be determined by one or more of the following methods: protocol agreement, network pre-configuration, network indication (or request), indication (or request) of other UEs (such as server UE, Rx UE, target UE, anchor UE, etc.), UE autonomous selection or determination, etc.

[0160] For example, when the first terminal autonomously selects or determines the indication method, it can determine the indication method of the first signaling according to the stability of the association relationship between the reference signal resource and the target object. For example, when the stability of the association relationship between the reference signal resource and the target object is better (such as different target objects are associated with different reference signal sequences in the same reference signal resource, etc.), the indication method of the first signaling can be determined to be a one-shot indication, otherwise, the indication method of the first signaling is determined to be the periodic indication or event-triggered indication, etc., without limitation here. Optionally, from the perspective of the stability of the association relationship, if the stability is better, it is indicated through a high-level message; if the association relationship is relatively dynamic, it is indicated through a physical layer message such as SCI.

[0161] For another example, when the first terminal determines the indication mode of the first signaling according to the network request or other terminal request, its implementation process may include: the first terminal receives the request signaling (such as the subsequent first signaling) sent by the network side device or other terminal, and the request signaling may carry the indication mode of the first signaling, such as one-shot indication, periodic indication, event-triggered indication, etc. Optionally, the one-shot indication, periodic indication, and event-triggered indication are applicable to indications through high-level messages.

[0162] Optionally, for SL transmission, the request for the first signaling also includes an indication of whether the first signaling is transmitted through SCI or a high-level message. For example, if the first terminal can support both the first signaling through SCI and the first signaling through a high-level message (SL high-level message, UL high-level message), the network device or other terminal can request the first terminal to indicate the first signaling through SCI, or to indicate the first signaling through a high-level message, or to indicate the first signaling through SCI and a high-level message to different devices respectively.

[0163] Of course, for the aforementioned first signaling, the first terminal may be triggered autonomously or by other devices. For example, in the case of being triggered by other devices, the first terminal may receive a first request sent by the first device or the third device, and send the first signaling to the first device according to the first request, thereby enabling the first signaling sent by the first terminal to meet the needs of the first device or the third device, and avoiding invalid sending of the signaling.

[0164] It is worth noting that when the first request is sent by the first device, the recipient of the first signaling is consistent with the requester, thereby enabling the first signaling sent by the first terminal to meet the needs of the first device and avoid invalid sending of the signaling.

[0165] When the first request is sent by the third device, the recipient of the first signaling is different from the requester, that is, the first signaling is scheduled by the third device for the first device. Therefore, on the one hand, it can meet the needs of the first device, and on the other hand, it can ensure the flexibility and applicability of the first signaling request.

[0166] Of course, in this embodiment, the first device may include but is not limited to a network side device or other terminals other than the first terminal, such as Rx UE, server UE, LMF, network side device (such as a base station) and other terminals for resource selection, etc. The third device may be a network side device or other terminal capable of data scheduling, etc., which is not limited here.

[0167] In this embodiment, the first request may carry or indicate at least one of the following (81)-(82).

[0168] (81) The indication method of the first signaling.

[0169] Among them, the indication method of the first signaling can be the aforementioned one-shot indication, periodic indication, event trigger indication, etc.

[0170] (82) An indication requirement corresponding to the indication method. For example, when the indication method of the first signaling is a one-shot indication, the indication requirement may be an interval between the one-shot indication and the first request, that is, an interval between the time when the first terminal sends the first signaling and the time when the first request is received.

[0171] For another example, when the indication mode of the first signaling is periodic indication, the indication requirement may be the period in the periodic indication, the interval between the first periodic indication and the first request, and the like.

[0172] For another example, when the indication mode of the first signaling is an event trigger indication, the indication requirement may be event information in the event trigger indication, such as a change in an association relationship between a target object and a reference signal resource.

[0173] It is worth noting that when the first terminal indicates the association relationship between the reference signal resource and the target object through the first signaling, the first signaling can be reported together with the association relationship between the sending time error group (Time Error Group, TEG) and the reference signal resource, thereby saving network overhead and improving reporting efficiency.

[0174] In one implementation, for a first device, if the first device receives a first reference signal sent by a first terminal, the first device may send a measurement result corresponding to the first reference signal to a second device, so that the second device can perform terminal positioning according to the measurement result, such as determining the terminal position according to measurement results associated with different target objects. The measurement result includes at least one of the following (91)-(95).

[0175] (91) The terminal ID that sends the first reference signal.

[0176] (92) Send the target object ID of the first reference signal resource.

[0177] (93) A timestamp of a reference signal resource corresponding to the first reference signal.

[0178] (94) An identifier of a reference signal resource corresponding to the first reference signal.

[0179] (95) Receive the target object ID of the first reference signal.

[0180] Optionally, for the target object ID contained in the measurement results described in (91)-(95) above, when the target object is ARP, the target object ID is ARP ID (such as Tx ARP ID); when the target object is beam, the target object ID is beam ID (or spatial relation ID, SL PRS resource set ID, SL PRS ID, etc.); when the target object is TEG, the target object ID is TEG ID (such as Tx TEG ID, or RxTx TEG ID), etc.

[0181] Of course, when the target object type of the reference signal resource can be multiple, the measurement result can include multiple types of target object IDs. For example, when the target object associated with the reference signal resource is at least one of ARP, beam, and TEG, the measurement result can include at least one of the ARP ID, beam ID, and TEG ID associated with the reference signal resource.

[0182] In one implementation, the second device may be the aforementioned first terminal, or may be a core network device, a location server, etc., or may be a device that sends the first request, etc., and is not limited here.

[0183] It is worth noting that in this embodiment, in addition to the aforementioned receiving end for receiving the first reference signal and the first signaling being the first device, in one implementation, the receiving end for receiving the first reference signal may be different from the receiving end for receiving the first signaling. For example, the receiving end for receiving the first reference signal may be the aforementioned first device, and the receiving end for receiving the first signaling may be a fourth device different from the first device. In this case, the fourth device may be a device that performs SL positioning solution, channel detection result solution, and channel estimation result solution based on the measurement result of the first reference signal provided by the first device, such as a location server, etc., and is not limited here. Therefore, by configuring the first reference signal and the first signaling to correspond to different receiving ends respectively, the efficiency and accuracy of SL positioning solution, channel detection result solution, and channel estimation result solution can be effectively improved.

[0184] In this embodiment, by indicating the association relationship between the reference signal resource and the target object through the first signaling, it is possible to avoid the Rx UE from jointly processing the measurement results corresponding to different transmission target objects (Tx target objects), thereby affecting the accuracy of the processing results, or it is possible to enable the LMF, server UE, LMF or core network equipment to clearly know which Tx target object the measurement result corresponds to, thereby assisting the LMF, server UE, LMF or core network equipment to perform position calculation according to different target object IDs to ensure the accuracy of the processing results.

[0185] In addition, for some scenarios, such as the terminal does not support multiple ARP measurements, or the terminal does not support multiple ARP sending, or the terminal needs to send signals through multiple ARPs, the multi-ARP positioning solution provided in the related technology from the perspective of reception and measurement is not applicable. From the perspective of ARP sending, the present application sends reference signals and indicates the association relationship based on the association relationship between ARP and reference signals, which can effectively improve the applicability of the ARP positioning solution and ensure the accuracy of the SL positioning scenario.

[0186] like Figure 4 As shown, it is a flow chart of a communication method 400 provided by an exemplary embodiment of the present application, and the method 400 can be, but is not limited to, executed by a first terminal, and can be specifically executed by hardware and / or software installed in the first terminal. In this embodiment, the method 400 can at least include the following steps.

[0187] S410: The first terminal obtains an association relationship between a reference signal resource and a target object.

[0188] S420: Send a first reference signal based on the association relationship between the reference signal resource and the target object.

[0189] The target object includes an antenna reference point, a beam or a time error group, and the association relationship between the reference signal resource and the target object includes different target objects being associated with different reference signal resources, or different target objects being associated with different reference signal sequences in the same reference signal resource.

[0190] It can be understood that, in addition to referring to the relevant descriptions in the aforementioned method embodiments 200 and 300, the implementation process of S410-S420, as a possible implementation mode, in addition to being able to act as a transmitting end to send reference signal resources, first signaling, etc. based on multiple target objects, the first terminal can also act as a measuring end or a receiving end to measure reference signals, report measurement results, etc. In this regard, the relevant behaviors of the first terminal as a measuring end or a receiving end are described below.

[0191] For example, when the first terminal serves as a measurement end, it can receive at least one second reference signal sent by devices other than itself (such as terminals, network side devices, etc.), and report the measurement results of the second reference signal, wherein the second reference signal includes an SL reference signal (such as SL PRS, CSI RS, etc.) or a DL reference signal (such as DL PRS, etc.).

[0192] It should be noted that when the first terminal determines the measurement result, the SL Reference Signal Time Difference (RSTD) included in the measurement result is calculated with reference to the measurement result corresponding to a specific terminal (also referred to as a reference terminal or anchor UE), that is, the RSTD is determined by the difference between the receiving time (Rx timing) of the SL positioning reference signal of multiple terminals and a specific terminal. Therefore, by defining a specific terminal, that is, taking the measurement result corresponding to the specific terminal as a reference, and measuring the SL-RSTD from the perspective of reception / measurement, the accuracy and feasibility of the SL-RSTD can be improved.

[0193] Taking into account that a specific terminal may have multiple target objects (such as multiple beams or multiple ARPs, etc.), making the measurement result of the specific terminal not unique, therefore, in this embodiment, a certain target object in the specific terminal can also be used as a reference target object to calculate the SLRSTD, such as calculating the SLRSTD with the measurement result corresponding to the specific target object in the specific terminal as a reference, so as to ensure the uniqueness of the reference time when calculating RSTD with the specific terminal as a reference, thereby ensuring the accuracy of the calculation result.

[0194] Corresponding to the measurement on SL, if the measurement result is based on DL implementation, then the DL RSTD included in the measurement result is calculated with reference to the measurement result corresponding to a specific TRP (also called a reference TRP). Therefore, by defining a specific TRP, that is, measuring SL-RSTD from the perspective of reception / measurement, the accuracy and feasibility of RSTD can be improved.

[0195] Also, similar to the specific target object in the aforementioned specific terminal, considering that a specific TRP may have multiple target objects, making the measurement result of the specific TRP not unique, a certain target object in the specific TRP can be used as a reference target object to calculate the SLRSTD. For example, the SLRSTD is calculated with the measurement result corresponding to the specific target object in the specific TRP as a reference, so as to ensure the uniqueness of the reference time when calculating RSTD with the specific TRP as a reference, thereby ensuring the accuracy of the calculation result.

[0196] It can be understood that the aforementioned specific terminal, specific target object, and specific TRP may be implemented by network indication, protocol agreement, indication from a terminal other than the first terminal, or autonomous determination by the first terminal, and no limitation is made here.

[0197] Based on this, in order to ensure that the first terminal and the device receiving the measurement result have a consistent understanding of the specific terminal or specific target object actually used by the first terminal when determining RSTD, in this embodiment, if the second reference signal is the SL reference signal, then the measurement result may also include one or more of the identifier of the specific terminal, the identifier of the specific target object in the specific terminal, etc., which is not limited here.

[0198] Similarly, when the second reference signal is the DL reference signal, the measurement result may also include one or more of the identifier of the specific TRP and the identifier of the specific target object in the specific TRP, which is not limited here.

[0199] In another implementation, when the first terminal serves as a measuring end, if SL transmit / receive (Rx-Tx) time difference measurement is performed based on a target object, the target object corresponding to the Tx time is the same as the target object corresponding to the Rx time, wherein the Tx time and the Rx time are used to calculate the SL Rx-Tx time difference. Thus, by restricting the target object corresponding to the Tx time and the target object corresponding to the Rx, the SL Rx-Tx time difference is calculated based on the same target object, thereby ensuring the calculation accuracy of the SLRx-Tx time difference.

[0200] Of course, if the first terminal performs SL Rx-Tx time difference measurement based on the target object, and the target object corresponding to the Tx time is different from the target object corresponding to the Rx, then the first terminal can report the identifier of the target object corresponding to the Tx time, so that the receiving end (such as a position calculation device, etc.) has a consistent understanding of the receiving target object and the sending target object involved in the SL Rx-Tx time difference, which is conducive to the receiving end to better match the Rx-Tx time difference measurement results between the two terminals.

[0201] In this embodiment, by defining the behavior of the first terminal as a measuring / receiving end, positioning accuracy can be further improved.
