[0017] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0018] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0019] The following explains some concepts and / or terms involved in the PRS processing method, apparatus and user equipment provided in the embodiments of this application.

[0020] 1. Carrier and bandwidth part (BWP)

[0021] NR has a relatively large bandwidth, and in many cases, it is not necessary to directly schedule a large bandwidth for data transmission. This led to the definition of a carrier. A carrier can sometimes be understood as a cell, but it is more of a frequency domain concept. A carrier can have four BWPs, and only one BWP is active.

[0022] 2. Carrier aggregation

[0023] Carrier aggregation refers to the ability of a UE to simultaneously transmit and receive data on two or more component carriers (CCs). In contrast, in non-aggregation scenarios, data can only be transmitted and received on the active BWP of a single carrier.

[0024] It should be noted that simultaneous transmission and reception here means that the UE schedules different transport blocks (TBs) on different communication terminals (CCs), so that the UE has more scheduling resources.

[0025] 3. Positioning frequency layer

[0026] NR positioning introduces a Positioning Reference Signal (PRS) for UE to perform positioning measurements. To complete positioning, the UE needs to measure the PRS transmitted by the TRP (Transmission Reference Point) of multiple cells. Typically, to ensure high-accuracy positioning, the network side configures a larger bandwidth PRS (the larger the PRS bandwidth, the higher the positioning accuracy).

[0027] NR positioning also defines a positioning frequency layer, which is a set of positioning reference signal (PRS) resources under a set of TRPs, with the same subcarrier spacing, CP type, pointA, bandwidth, comb size. One positioning frequency layer can contain multiple TRPs, each TRP can contain multiple PRS resource sets, and each PRS resource set can contain multiple PRS resources. Currently, according to UE capability, only one positioning frequency layer PRS can be processed at the same time.

[0028] 4. PRS sequence generation and mapping

[0029] The PRS sequence is generated from a gold sequence, where the generation parameter Cinit is related to the PRS sequence ID, the symbol index of the PRS, the slot index, the number of symbols within the slot, etc.

[0030] When mapping the PRS sequence, the starting position can be calculated according to the reference point A of the positioning frequency layer, i.e. a certain TRP under a positioning frequency layer has an independent PRS sequence and is independently mapped.

[0031] It is worth noting that the technology described in the embodiments of the present application is not limited to long term evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency-division multiple access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used in the above-mentioned systems and radio technologies, as well as other systems and radio technologies. However, the following description describes a new radio (NR) system for example purposes, and NR terminology is used in most of the following description, and these technologies can also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

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

[0035] It should be noted that in the embodiments of the present application, the network device can be a location server or a serving base station.

[0038] The PRS processing method provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0039] The embodiment of the present application provides a PRS processing method, Figure 2 A flow chart of a PRS processing method provided by the embodiment of the present application is shown. As shown in the figure, Figure 2 The PRS processing method provided by the embodiment of the present application can include the following steps 201 and 202.

[0040] Step 201, the UE simultaneously processes PRS of at least one target positioning frequency layer.

[0041] Step 202, the UE performs positioning according to the PRS of the at least one target positioning frequency layer.

[0042] In the embodiment of the present application, each target positioning frequency layer in the at least one target positioning frequency layer includes a plurality of PRS.

[0043] In the embodiment of the present application, the PRS of the at least one target positioning frequency layer is used for the UE to perform positioning. The UE can be positioned according to the processing result after simultaneously processing the PRS of the at least one target positioning frequency layer. It should be noted that the processing of the PRS in the embodiment of the present application can also be understood as the measurement of the PRS.

[0044] It should be noted that the number of PRS included in the positioning frequency layer in the at least one target positioning frequency layer is different or the same, or the number of PRS included in part of the positioning frequency layer in the at least one target positioning frequency layer is the same. The PRS of the at least one target positioning frequency layer can include: a plurality of PRS of one target positioning frequency layer, or PRS of a plurality of target positioning frequency layers (that is, at least one PRS in each target positioning frequency layer in the plurality of target positioning frequency layers).

[0045] In the embodiment of the present application, in the NR positioning scenario, the UE can simultaneously measure and / or process the PRS of at least one target positioning frequency layer (for example, the PRS of a plurality of carriers in one positioning frequency layer, or the PRS of a plurality of positioning frequency layers), to uniformly perform sequence generation and sequence mapping of the PRS.

[0046] It should be noted that the UE simultaneously processing PRS of at least one target positioning frequency layer can be understood as: the UE simultaneously processing PRS of at least one target positioning frequency layer under a certain TRP or a certain gNB; or, the same multiple TRPs are contained in the multiple positioning frequency layers simultaneously processed, and PRS of at least one target positioning frequency layer is simultaneously processed, that is, for each TRP, PRS of at least one positioning frequency layer under a certain TRP or a certain gNB is simultaneously processed. The UE simultaneously processing PRS can be understood as: the UE processing PRS on the same symbol or on the same (or overlapping) multiple symbols, or the UE processing multiple PRS in the same time unit.

[0047] Optionally, in the embodiment of the present application, the at least one target positioning frequency layer is determined by any of the following: protocol agreement, configuration information of the network device, and UE self-definition.

[0048] Optionally, in the embodiment of the present application, the configuration information includes at least one of the following: positioning frequency layer information and positioning frequency layer group information. The positioning frequency layer information is used to indicate at least one positioning frequency layer, and the positioning frequency layer group information is used to indicate at least one positioning frequency layer group, each positioning frequency layer group including one or more positioning frequency layers.

[0049] It can be understood that, in the case that the configuration information includes the positioning frequency layer information, the at least one target positioning frequency layer is at least one positioning frequency layer indicated by the positioning frequency layer information; in the case that the configuration information includes the positioning frequency layer group information, the at least one target positioning frequency layer is a positioning frequency layer in at least one positioning frequency layer group; in the case that the configuration information includes the positioning frequency layer information and the positioning frequency layer group information, the at least one target positioning frequency layer includes at least one positioning frequency layer indicated by the positioning frequency layer information and a positioning frequency layer in at least one positioning frequency layer group.

[0050] Optionally, in the embodiment of the present application, each positioning frequency layer group can include one or multiple positioning frequency layers simultaneously. It should be noted that the multiple positioning frequency layers simultaneously can be understood as: multiple positioning frequency layers with overlapping time domain resources.

[0051] Optionally, in embodiments of the present application, the positioning frequency layer group information can be implicitly configured, that is, a plurality of positioning frequency layers are configured to be transmitted simultaneously, and the plurality of positioning frequency layers can be considered as a positioning frequency layer group, but the concept of positioning frequency layer group is not embodied. For example, when the network device configures a plurality of positioning frequency layers, and the plurality of positioning frequency layers have the same TRP (or TRP list), the same subcarrier spacing (SCS), and the same transmission characteristics, the UE can assume that the plurality of positioning frequency layers belong to the same positioning frequency layer group, or form the same positioning frequency layer group.

[0052] Optionally, in embodiments of the present application, each positioning frequency layer includes at least one carrier, and each carrier includes at least one PRS.

[0053] It should be noted that each carrier can represent a continuous channel bandwidth part, that is, the carrier in embodiments of the present application can also be expressed as a channel bandwidth part.

[0054] Optionally, in embodiments of the present application, each positioning frequency layer can include one or multiple carriers simultaneously. It should be noted that the multiple carriers simultaneously can be understood as multiple carriers with overlapping time domain resources.

[0055] It should be noted that the PRS in embodiments of the present application can also be referred to as a PRS resource or a PRS resource set. Optionally, the PRS can also be referred to as an aggregated PRS, or an aggregated PRS resource, or an aggregated PRS resource set, or a PRS that needs to be aggregated (or an aggregated PRS indication).

[0056] Optionally, in embodiments of the present application, the step 201 can be implemented by the following step 201a or step 201b.

[0057] The step 201a includes simultaneously performing, by the UE, aggregation processing on the PRS of the at least one target positioning frequency layer.

[0058] It should be noted that in embodiments of the present application, the aggregation processing refers to aggregating a plurality of PRSs in the frequency domain, that is, equivalent to a PRS with a larger bandwidth. The UE simultaneously performing aggregation processing on the PRS of the at least one target positioning frequency layer can be understood as the UE simultaneously performing aggregation processing on the PRS of all target positioning frequency layers, that is, the UE performing aggregation processing on the PRS of all target positioning frequency layers in the same symbol.

[0059] In embodiments of the present application, the UE can simultaneously perform aggregation processing on the PRS of the at least one target positioning frequency layer to improve the effective bandwidth, thereby improving the positioning accuracy (the larger the PRS bandwidth, the higher the positioning accuracy).

[0060] Optionally, in embodiments of the present application, the step 201a can be implemented by the following step 201a1.

[0061] In the step 201a1, the UE performs the aggregation processing on the PRS of the partial or all carriers of the at least one target positioning frequency layer according to the aggregation processing indication information.

[0062] In embodiments of the present application, the aggregation processing indication information in the step 201a1 is used to indicate the UE to perform the aggregation processing on the PRS of the partial or all carriers in the multiple carriers.

[0063] It can be understood that each positioning frequency layer includes at least one carrier; in the case that the at least one target positioning frequency layer is one positioning frequency layer and the one positioning frequency layer includes multiple carriers, the UE can perform the aggregation processing on the PRS of the partial or all carriers in the multiple carriers of the one positioning frequency layer. In the case that the at least one target positioning frequency layer is multiple positioning frequency layers and each positioning frequency layer in the multiple positioning frequency layers includes one or more carriers, the UE can perform the aggregation processing on the PRS of the partial or all carriers in all carriers of the multiple positioning frequency layers.

[0064] Optionally, in embodiments of the present application, the aggregation processing indication information can also be implicitly indicated, that is, it can indicate other contents, and the UE can perform the aggregation processing on the corresponding positioning frequency layer according to the indicated contents. For example, when the network device indicates the positioning frequency layer group or the positioning frequency layer has multiple channel bandwidth parts, the UE can perform the aggregation processing on the positioning frequency layers in the positioning frequency layer group or on the multiple channel bandwidths in the positioning frequency layer.

[0065] Optionally, in embodiments of the present application, the aggregation processing indication information can not be applied to the UE-based positioning scenario, that is, in the UE-based positioning scenario, the UE does not perform the aggregation processing on the PRS of the positioning frequency layer according to the indication of the aggregation processing indication information, or in the UE-based positioning scenario, the UE does not expect to be indicated / configured the aggregation processing indication information.

[0066] Optionally, in embodiments of the present application, the aggregation processing indication information is information carried in the configuration information of the network device or information carried in the location information request signaling sent by the network device.

[0067] Optionally, in embodiments of the present application, the PRS of the different carriers of the partial or all carriers of the at least one target positioning frequency layer satisfies the first preset condition.

[0068] Optionally, in embodiments of the present application, the first preset condition comprises at least one of the following: the SCSs of the PRSs are the same, the cyclic prefix (CP) types of the PRSs are the same, the periods of the PRSs are the same, the comb sizes of the PRSs are the same, the target reference points of the PRSs are the same, the resource element (RE) offsets of the PRSs are the same, any REs where the PRSs are located satisfy a second preset condition, sequences of the PRSs are mapped according to a first preset manner, the relative RE offsets of the PRSs are the same, the sequence IDs of the PRSs are the same, the slot numbers of slots where the PRSs are located are the same, the symbol numbers of symbols where the PRSs are located are the same, the system frame numbers (SFNs) of SFNs where the PRSs are located are the same, SFN0 offsets between SFN0s associated with the PRSs are 0, and the same spatial transmission filters associated with the PRSs.

[0069] It should be noted that, in the case of the PRS being a periodic signal, the first preset condition can comprise that the periods of the PRSs are the same. The any REs where the PRSs are located can be understood as any REs where PRSs of different carriers are located, or any REs where PRSs of different positioning frequency layers are located. For example, any REs where PRSs of a carrier 1 are located and any REs where PRSs of a carrier 2 are located satisfy the second preset condition; or any REs where PRSs of a positioning frequency layer 1 are located and any REs where PRSs of a positioning frequency layer 2 are located satisfy the second preset condition.

[0070] Optionally, in embodiments of the present application, the second preset condition is any one of the following: a frequency domain offset between any REs where the PRSs are located is an integer multiple of a product of a comb size and an SCS, and a difference in the number of REs between any REs where the PRSs are located is an integer multiple of the comb size.

[0071] Optionally, in embodiments of the present application, the any REs where the PRSs are located can be the lowest REs of the PRSs. It should be noted that the lowest REs of the PRSs can be understood as the lowest RE positions in a starting physical resource block (PRB) of the PRSs.

[0072] Optionally, in embodiments of the present application, the first preset condition and the second preset condition are both agreed upon by a protocol or configured by a network device.

[0073] Optionally, in the embodiments of this application, the target reference point includes at least one of the following: a reference starting point used when generating the PRS sequence, a reference starting point used when mapping the PRS sequence, and a reference starting point corresponding to the starting position of the PRS.

[0074] It should be noted that the target reference point of the PRS is the same, which may include at least one of the following: the same target reference starting point is used when generating the PRS sequence (the target reference point is used as the reference starting point to generate the sequence when generating the PRS sequence), the same target reference starting point is used when mapping the PRS sequence (that is, the target reference point is used as the reference starting point to map the sequence when mapping the PRS sequence), and the starting position of the PRS is referenced by the same target reference point (that is, the starting position of different PRS is referenced by this target reference point A).

[0075] Optionally, in the embodiments of this application, the above-mentioned at least one target positioning frequency layer shares the same reference point A, and the maximum value of the PRS start position (start PRB) can be greater than 2176.

[0076] Optionally, in this embodiment of the application, the target reference point can be reference point A.

[0077] Optionally, in the embodiments of this application, the first preset method is any one of the following: continuous PRS sequence mapping method / continuous PRS mapping method, non-continuous PRS sequence mapping method / non-continuous PRS mapping method.

[0078] Optionally, in this embodiment of the application, the network device may instruct the UE to use either a continuous mapping PRS sequence or a non-continuous mapping PRS sequence.

[0079] It should be noted that during PRS sequence mapping, even if there is channel spacing between PRSs, the PRS sequences are still mapped continuously. Alternatively, during PRS sequence mapping, the PRS sequences are mapped discontinuously, with the starting PRB of each PRS as the starting point for mapping the corresponding PRS sequence position.

[0080] For example, suppose a long PRS sequence is generated, and two positioning frequency layer PRSs share this long PRS sequence. Each of the two positioning frequency layer PRSs consists of a PRS with 100 REs, and the channel spacing between the PRSs is equivalent to 20 REs. This means that each of the two positioning frequency layer PRSs (PRS1 and PRS2) requires a sequence of length 100.

[0081] The sequence continuous mapping of the PRS means that PRS1 and PRS2 are mapped using a continuous sequence in a long sequence (for example, a sequence of 200 continuous lengths), and the interruption caused by the channel interval is not considered during the mapping.

[0082] The sequence non-continuous mapping of the PRS means that PRS1 is mapped using a continuous sequence in a long sequence, and PRS2 is mapped using another continuous sequence after a sequence equivalent to the channel interval. For example, PRS1 is mapped using a sequence of 100 continuous lengths in a long sequence, and after a sequence of 20 lengths (considering the influence of the channel interval), PRS2 is mapped using a sequence of 100 continuous lengths.

[0083] It should be noted that the slot numbers of the slots where the PRS is located are the same, which can be understood as the slot numbers or slot indexes in the radio frame being the same. The symbol numbers of the symbols of the PRS are the same, which can be understood as the symbol numbers or symbol indexes in the slot being the same.

[0084] It should be noted that the SFN0 offset between the SFN0s associated with the PRS is 0, which can be understood as the SFN timings of different PRSs being aligned, that is, carrier aggregation (CA).

[0085] Optionally, in the embodiments of the present application, if the SFN0 offset between the SFN0s associated with the PRS is not 0, the UE does not expect to aggregate the PRS, for example, the UE does not expect the SFN timings associated with multiple PRSs to be different (out of synchronization).

[0086] Optionally, in the embodiments of the present application, the SFN0 offset between the SFN0s associated with the PRS is an integer multiple of the length of a radio frame (10 ms), so that the slot numbers and symbol numbers of the slots where the PRS is located are the same.

[0087] It should be noted that the PRSs associated with the same spatial transmission filter can be understood as multiple PRSs being emitted from the same spatial transmission filter to form the same beam, or the corresponding antenna ports of the multiple PRSs being the same. The PRSs associated with the same spatial transmission filter can also be represented as having the same quasi co-location (QCL) spatial reference signal.

[0088] Optionally, in the embodiments of the present application, for the PRS of at least one target positioning frequency layer, the target numbers used during the sequence generation or sequence mapping of the PRS of at least two carriers are the same. The target numbers include at least one of the following: a symbol number and a slot number.

[0089] Specifically, the slot number is a slot index / slot number within a radio frame, and the symbol number is a symbol index / symbol number within a slot. In other words, for the same symbol, for PRSs located in different positioning frequency layers, or for PRSs located in different carriers, the UE should assume that the same symbol number and / or slot number are used in generating the sequence or mapping the sequence.

[0090] Optionally, in an embodiment of the present application, the at least two carriers are determined according to any one of the following: a protocol agreement, network device indication, and UE self-definition.

[0091] Optionally, in an embodiment of the present application, the UE can generate the sequence of the PRS and / or map the sequence of the PRS according to the SFN timing of the target positioning frequency layer according to a protocol agreement or indication information sent by the network device. It can be understood that the network device can indicate the UE to take the SFN timing of a certain positioning frequency layer as a reference to generate and / or map the sequence of the PRS when generating and / or mapping the sequence of the PRS of at least one target positioning frequency layer.

[0092] Optionally, in an embodiment of the present application, the UE can generate the sequence of the PRS and / or map the sequence of the PRS according to the SFN timing of the target carrier according to a protocol agreement or indication information sent by the network device. It can be understood that the network device can indicate the UE to take the SFN timing of a certain carrier as a reference to generate and / or map the sequence of the PRS when generating and / or mapping the sequence of the PRS of multiple carriers (i.e., part of the carriers or all the carriers of at least one target positioning frequency layer).

[0093] It can be understood that the UE can generate the sequence of the PRS and / or map the sequence of the PRS according to the SFN timing of a specific positioning frequency layer or a specific channel bandwidth part, i.e., the specific positioning frequency layer can be taken as a reference positioning frequency layer, and the specific channel bandwidth part can be taken as a reference channel bandwidth part. The specific positioning frequency layer or the specific channel bandwidth part is determined according to a protocol agreement or network device indication.

[0094] Optionally, in an embodiment of the present application, the sequence generation manner of the PRS of the at least one target positioning frequency layer includes at least one of the following: an independent generation manner, a joint generation manner.

[0095] Optionally, in an embodiment of the present application, the sequence mapping manner of the PRS of the at least one target positioning frequency layer includes at least one of the following: an independent mapping manner, a joint mapping manner.

[0096] Optionally, in the embodiments of the present application, the sequence generation manner and the sequence mapping manner of the PRS of the at least one target positioning frequency layer can be indicated by a protocol or a network device.

[0097] It can be understood that the UE can determine whether the PRS of the at least one target positioning frequency layer is generated in a sequence-independent manner or in a sequence-joint manner, and / or determine whether the PRS of the at least one target positioning frequency layer is mapped in a sequence-independent manner or in a sequence-joint manner, according to the protocol or the indication of the network device. For example, the sequence generation manner of the PRS of the at least one target positioning frequency layer is a sequence-independent generation manner, and the sequence mapping manner of the PRS of the at least one target positioning frequency layer is a sequence-independent mapping manner or a sequence-joint mapping manner.

[0098] It should be noted that the sequence-joint generation / sequence-joint mapping can be understood as using the same long sequence for generation / mapping. For example, when performing sequence mapping, multiple PRSs use the same symbol number, time slot number and / or target reference point (for example, reference point A). The sequence-independent generation / mapping can be understood as using different reference points, symbol numbers and / or time slot numbers for multiple PRSs.

[0099] Optionally, in the embodiments of the present application, the configuration information of the positioning frequency layer includes the configuration of multiple carriers at the same time, and before processing the PRS of the at least one target positioning frequency layer, the UE can further receive indication information sent by the network device, and the indication information is used to indicate at least one of the following information of the multiple carriers: a band indicator of each carrier, a relationship between the multiple carriers (including intra-band non-contiguous carrier aggregation, intra-band contiguous carrier aggregation or inter-band carrier aggregation), and the like.

[0100] Optionally, in the embodiments of the present application, after processing the PRS of the at least one target positioning frequency layer, the UE can report a measurement result to the network device, and the measurement result can include at least one of the following:

[0101] (1) How the UE processes the PRS of different positioning frequency layers or different carriers. The processing manner can be to directly perform aggregation of a large bandwidth sequence processing, or to combine the positioning frequency layers or carriers after obtaining the measurement results (such as TDOA measurement results, time measurement results) of the positioning frequency layers or carriers respectively, or a combination of the above two manners (for example, performing aggregation processing on some positioning frequency layers or carriers, and then combining the other positioning frequency layers or carriers after processing them respectively).

[0102] (2) whether to use measurement gap or BWP measurement when the UE processes PRS of different positioning frequency layers or different carriers. For example, whether all positioning frequency layers or carriers use measurement gap (or BWP measurement), or part of the positioning frequency layers or carriers use measurement gap, and the other positioning frequency layers or carriers use BWP measurement.

[0103] Optionally, in embodiments of the present application, if the UE uses BWP measurement PRS, the measurement result further includes BWP-related configurations, such as at least one of frequency domain position information of the BWP and frequency domain position information of the carrier where the BWP is located.

[0104] Optionally, in embodiments of the present application, when the UE processes PRS of at least one target positioning frequency layer, if no measurement gap is configured, the UE processes PRS on all active BWP of all active carriers within the bandwidth of the at least one target positioning frequency layer.

[0105] Optionally, in embodiments of the present application, if the network device indicates aggregation processing, the UE aggregates and processes PRS on all active BWP of all active carriers within the bandwidth of the at least one target positioning frequency layer.

[0106] Optionally, in embodiments of the present application, the step 201a can be implemented by the following step 201a2.

[0107] In step 201a2, the UE simultaneously aggregates and processes PRS of part of the positioning frequency layers or all positioning frequency layers in the at least one positioning frequency layer group according to the aggregation processing indication information.

[0108] In embodiments of the present application, the aggregation processing indication information in the step 201a2 is used to indicate the UE to aggregate and process PRS of part of the positioning frequency layers or all positioning frequency layers in the positioning frequency layer group.

[0109] It can be understood that each positioning frequency layer group includes at least one positioning frequency layer; in the case that the at least one target positioning frequency layer is one positioning frequency layer group and the one positioning frequency layer group includes multiple positioning frequency layers, the UE can aggregate and process PRS of part of the positioning frequency layers or all positioning frequency layers in the multiple positioning frequency layers of the one positioning frequency layer group. In the case that the at least one target positioning frequency layer is multiple positioning frequency layer groups and each positioning frequency layer group in the multiple positioning frequency layer groups includes one or more positioning frequency layers, the UE can aggregate and process PRS of part of the positioning frequency layers or all positioning frequency layers in all positioning frequency layers of the multiple positioning frequency layer groups.

[0110] Optionally, in embodiments of the present application, for PRS of part of the positioning frequency layers or all positioning frequency layers in the at least one positioning frequency layer group, PRS of different positioning frequency layers satisfies a first preset condition.

[0111] Optionally, in embodiments of the present application, for PRS of part of the frequency layers or all of the positioning frequency layers in the at least one positioning frequency layer group, the same target number is used when performing sequence generation or sequence mapping on PRS of at least two positioning frequency layers.

[0112] Optionally, in embodiments of the present application, the at least two positioning frequency layers are determined by any of the following: protocol agreement, network device indication, and UE self-definition.

[0113] It should be noted that, for the aggregation processing indication information in step 201a2, the first preset condition, etc., reference can be made to the related description in step 201a1 in the above embodiments, which will not be repeated here.

[0114] In embodiments of the present application, PRS located in different positioning frequency layers or PRS located in different carriers have the above characteristics (i.e., meet the first preset condition, such as the same slot number of the slot where the PRS is located, the same symbol number of the PRS symbol, the same SFN number of the system frame number SFN where the PRS is located, etc.), and the UE can simultaneously process PRS from multiple positioning frequency layers or multiple carriers, so that PRS of multiple positioning frequency layers or multiple carriers share the same sequence and are uniformly mapped, to solve the two existing problems: (1) At the same time, the symbol index or slot index of PRS on different positioning frequency layers or carriers is not necessarily the same, resulting in the problem of being unable to uniformly generate sequences; (2) There is a channel interval between different positioning frequency layers or carriers, and PRS has the characteristic of equal interval distribution on one symbol, how to ensure the equal interval distribution characteristic of PRS in the presence of a channel interval.

[0115] In step 201b, the UE simultaneously performs non-aggregation processing on PRS of at least one target positioning frequency layer.

[0116] It should be noted that, in embodiments of the present application, non-aggregation processing refers to processing each of the multiple PRS in the frequency domain respectively. The UE simultaneously performing non-aggregation processing on PRS of at least one target positioning frequency layer can be understood as: the UE simultaneously processes PRS of each target positioning frequency layer, i.e., the UE processes PRS of each target positioning frequency layer on the same symbol respectively.

[0117] The embodiment of the present application provides a PRS processing method, and the UE can simultaneously process PRS of at least one target positioning frequency layer, and each target positioning frequency layer includes a plurality of PRS. In the scenario of one or more positioning frequency layers, the UE can simultaneously process a plurality of PRS of one positioning frequency layer or a plurality of PRS of a plurality of positioning frequency layers by the present scheme, so as to realize PRS processing of one or more positioning frequency layers, thereby realizing unified sequence generation and sequence mapping of PRS.

[0118] Optionally, in the embodiment of the present application, in combination with Figure 2 As shown in the above step 201, the PRS processing method provided by the embodiment of the present application further includes the following steps 301 and 302 before the above step 201. Figure 3

[0122] It should be noted that the above triggering signaling can also be understood as activation signaling.

[0123] Optionally, in the embodiment of the present application, the above triggering signaling is any of the following: DCI signaling and MAC CE signaling.

[0130] Optionally, in the embodiments of the present application, the target MG is preconfigured or agreed by a protocol.

[0131] Optionally, in the embodiments of the present application, the trigger signaling is specifically used for triggering the UE to simultaneously process PRS of carriers of at least one positioning frequency layer. Before step 201, the PRS processing method provided by the embodiments of the present application further comprises the following step 401.

The preconfigured information includes information of at least one positioning frequency layer (i.e., at least one item of information included in the first target information).

[0135] Optionally, in the embodiments of the present application, for each positioning frequency layer in the at least one positioning frequency layer, the triggering offset of the PRS of the plurality of carriers in the one positioning frequency layer is the same.

[0136] Optionally, in the embodiments of the present application, for each positioning frequency layer in the at least one positioning frequency layer, the triggering offset of the PRS of the one positioning frequency layer can be a time offset between DCI signaling and the one positioning frequency layer.

[0137] It should be noted that the at least one first triggering identifier can be understood as a triggering identifier of at least one positioning frequency layer. Each positioning frequency layer has a corresponding triggering identifier. When the triggering identifier in the triggering signaling is the same as the triggering identifier of a certain positioning frequency layer, the UE is triggered to process the PRS of the certain positioning frequency layer.

[0138] Optionally, in the embodiments of the present application, when the triggering identifier is 0, it can represent that the UE is not triggered to process the PRS of the positioning frequency layer.

[0139] Optionally, in the embodiments of the present application, the same triggering identifier can be allocated to a plurality of positioning frequency layers, so that after receiving the triggering signaling, when the triggering identifier in the triggering signaling is the same as the triggering identifier of the plurality of positioning frequency layers, the UE can process the PRS of the plurality of positioning frequency layers.

[0140] It should be noted that the spatial relationship information of the PRS of the at least one positioning frequency layer can also be represented as QCL information of the PRS of the at least one positioning frequency layer.

[0142] Optionally, in the embodiments of the present application, for the sequence information allocated in the trigger signaling block by the at least one positioning frequency layer, when the trigger signaling block is a DCI block, in one way, one DCI can be used to trigger multiple positioning frequency layers, the indication information of the multiple positioning frequency layers is allocated in the DCI in sequence, and the UE can extract the DCI indication information corresponding to different positioning frequency layers respectively according to the sequence information; in another way, one DCI can be used to trigger multiple carriers in a positioning frequency layer, the indication information of the multiple carriers is allocated in the DCI in sequence, and the UE can extract the DCI indication information corresponding to different carriers according to the sequence information.

[0143] Optionally, in another implementation manner of the embodiments of the present application, the trigger signaling is specifically used to trigger the UE to process the PRS of the positioning frequency layers in at least one positioning frequency layer group indicated by the positioning frequency layer group information at the same time.

[0144] Optionally, in the embodiments of the present application, in the case that the trigger signaling is specifically used to trigger the UE to process the PRS of the positioning frequency layers in at least one positioning frequency layer group at the same time, the trigger signaling includes second trigger information of the at least one positioning frequency layer group, and the second trigger information includes at least one of the following: at least one second trigger identifier, aggregation processing indication information, at least one positioning frequency layer group identifier, and MG indication information.

[0145] wherein each of the second trigger identifiers respectively corresponds to one of the at least one positioning frequency layer group; the aggregation processing indication information is used to indicate whether the UE performs aggregation processing on part of the at least one positioning frequency layer group or all of the at least one positioning frequency layer group; each of the positioning frequency layer group identifiers is used to indicate one of the at least one positioning frequency layer group; and the MG indication information is used to indicate whether the UE uses the MG to process the at least one positioning frequency layer group, or is used to indicate that the UE uses a target MG to process the at least one positioning frequency layer group.

[0146] It should be noted that the at least one second trigger identifier is used to trigger the at least one positioning frequency layer group, and after receiving the trigger signaling, the UE can determine, according to the at least one second trigger identifier in the trigger signaling, a positioning frequency layer in the at least one positioning frequency layer group corresponding to the at least one second trigger identifier as at least one target positioning frequency layer, and simultaneously process PRS of the at least one target positioning frequency layer. The aggregation processing indication information used to indicate whether the UE performs aggregation processing on part of the at least one positioning frequency layer group or all of the at least one positioning frequency layer group can be understood as: the aggregation processing indication information is used to indicate whether the UE performs aggregation processing on the at least one positioning frequency layer group, or is used to indicate whether the UE performs aggregation processing on some positioning frequency layer groups (for example, specific positioning frequency layer groups) of the at least one positioning frequency layer group.

[0147] Optionally, in the embodiments of the present application, the aggregation processing indication information can be applied to a scenario in which the MG only supports aggregation of part of the positioning frequency layers in the positioning frequency layer group.

[0148] Optionally, in the embodiments of the present application, the trigger signaling is specifically used to trigger the UE to simultaneously process PRS of the positioning frequency layers in the at least one positioning frequency layer group. Before the step 201, the PRS processing method provided by the embodiments of the present application further includes the following step 501.

[0149] In step 501, the UE acquires second target information.

[0151] It should be noted that the second target information can be understood as information pre-configured by the network device to assist the UE in processing the PRS of the positioning frequency layer group. The pre-configured information includes information of at least one positioning frequency layer group (i.e., at least one item of information included in the second target information).

[0152] Optionally, in an embodiment of the present application, for each positioning frequency layer group in the at least one positioning frequency layer group, the PRS of the multiple positioning frequency layers in the one positioning frequency layer group has the same trigger offset.

[0153] Optionally, in an embodiment of the present application, for each positioning frequency layer group in the at least one positioning frequency layer group, the trigger offset of the PRS of the one positioning frequency layer group can be a time offset between the DCI signaling and the one positioning frequency layer group.

[0154] Optionally, in an embodiment of the present application, for each positioning frequency layer group in the at least one positioning frequency layer group: the trigger offset of the PRS of the one positioning frequency layer group can be an offset or a subframe offset between the DCI signaling and the earliest PRS resource set in the one positioning frequency layer group. Alternatively, the trigger offset of the PRS of the one positioning frequency layer group can be an offset between the DCI signaling and a measurement window start position associated with the one positioning frequency layer group.

[0155] Optionally, in an embodiment of the present application, the unit of the trigger offset can be: a time slot, a subframe, a symbol, or an SFN. For example, the DCI signaling, the PRS resource set, and the PRS measurement window position can be understood as the time slot, the subframe, or the symbol in which they are located.

[0156] It should be noted that the at least one second trigger identifier can be understood as a trigger identifier of the at least one positioning frequency layer group. Each positioning frequency layer group has a corresponding trigger identifier. When the trigger identifier in the trigger signaling is the same as the trigger identifier of a certain positioning frequency layer group, the UE is triggered to process the PRS of the certain positioning frequency layer group.

[0157] Optionally, in an embodiment of the present application, when the trigger identifier is 0, it can indicate that the UE is not triggered to process the PRS of the positioning frequency layer group.

[0158] Optionally, in an embodiment of the present application, the same trigger identifier can be assigned to multiple positioning frequency layer groups, so that after the UE receives the trigger signaling, when the trigger identifier in the trigger signaling is the same as the trigger identifier of the multiple positioning frequency layer groups, the UE can process the PRS of the multiple positioning frequency layer groups.

[0159] It should be noted that the spatial relationship information of the PRS of the at least one positioning frequency layer group can also be represented as QCL information of the PRS of the at least one positioning frequency layer group.

[0160] Optionally, in the embodiments of the present application, for the position information of the trigger signaling block corresponding to the at least one positioning frequency layer group, when the trigger signaling block is a DCI block (DCI block), in one way, the DCI group (group DCI) can be used to trigger multiple positioning frequency layer groups, the DCI group includes multiple DCI blocks, each positioning frequency layer group corresponds to a DCI block in the group DCI, and the UE can determine the DCI indication information corresponding to the multiple positioning frequency layer groups respectively according to the position information allocated in advance; in another way, the DCI group can be used to trigger multiple positioning frequency layers in a positioning frequency layer group, the DCI group includes multiple DCI blocks, each positioning frequency layer corresponds to a DCI block in the group DCI, and the UE can determine the DCI indication information corresponding to the multiple positioning frequency layers respectively according to the position information allocated in advance.

[0163] The step 201c, after the UE receives the trigger signaling for a preset time length, the UE processes the PRS of the at least one target positioning frequency layer at the same time.

[0164] It can be understood that after receiving the trigger signaling, the UE can not directly process the PRS of the at least one target positioning frequency layer, but after a time threshold (i.e., a preset time length), the UE processes the PRS of the at least one target positioning frequency layer. In other words, within a time threshold after receiving the trigger signaling, the UE does not expect to process the PRS of the at least one target positioning frequency layer at the same time.

[0165] Optionally, in the embodiments of the present application, the above-mentioned preset time length can be indicated by a network device, agreed by a protocol or reported by a UE.

[0166] Optionally, in embodiments of the present application, the preset time length is related to a radio frequency retuning (RF retuning) time.

[0167] Optionally, in embodiments of the present application, the preset time length includes a time for the UE to perform radio frequency retuning, for example, when the UE simultaneously processes multiple positioning frequency layers, the UE needs to tune each positioning frequency layer before measuring and / or processing PRS.

[0171] The UE uses a preset receive beam to process PRS of the at least one target positioning frequency layer.

[0172] The first time interval is the interval between the start time of the UE simultaneously processing PRS of the at least one target positioning frequency layer and the time of receiving the triggering signaling.

[0173] It should be noted that the UE not processing PRS of the at least one target positioning frequency layer can be understood as the UE not expecting to measure and / or process PRS of the at least one target positioning frequency layer. The UE not using a target receive beam to process PRS of the at least one target positioning frequency layer can be understood as the UE not expecting to apply a target receive beam to measure and / or process PRS of the at least one target positioning frequency layer.

[0174] Optionally, in embodiments of the present application, the preset receive beam can be an alternative or default beam, which can be any of the following: a receive beam corresponding to the triggering signaling, a receive beam for beam sweeping, a wide beam, a receive beam of a fixed direction, a default beam indicated by the network device, etc.

[0183] Step 601, the network device sends the update signaling to the UE.

[0184] Step 602, the UE receives the update signaling sent by the network device.

[0186] Optionally, in embodiments of the present application, the UE can receive the preconfigured update signaling to update the related configuration of the PRS before receiving the trigger signaling and after receiving the preconfigured information (i.e., the first target information or the second target information).

[0187] Optionally, in embodiments of the present application, the update signaling can be a MAC CE signaling.

[0188] Optionally, in embodiments of the present application, the second time interval is less than or equal to the second threshold value, and the second time interval is the time interval between adjacent two times of processing the PRS of the at least one target positioning frequency layer by the UE at the same time.

[0189] It can be understood that the UE can measure and / or process the PRS of the at least one target positioning frequency layer at the same time for multiple times, and the time interval between adjacent two times of measurement and / or processing is less than or equal to the second threshold value.

[0190] Optionally, in embodiments of the present application, the second threshold value can be indicated by the network device, agreed by the protocol or reported by the UE.

[0191] Optionally, in embodiments of the present application, the second threshold is related to RF retuning time, beam switching, or processing capability of the UE, etc.
