Detailed ways

The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of this application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that data so used may be interchanged under appropriate circumstances so that embodiments of the application can be practiced in sequences other than those illustrated or described herein. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

Some concepts and/or terms involved in the PRS processing method, apparatus, and user equipment provided by the embodiments of the present application are explained below.

1. Carrier and bandwidth part (BWP)

The bandwidth of NR is relatively large. In many cases, it is not necessary to directly schedule a large bandwidth for data transmission. Therefore, with the definition of the carrier, the carrier can sometimes be understood as a cell, but the carrier is more of a frequency. domain concept. A carrier can have four BWPs, and only one BWP is active.

2. Carrier aggregation

Carrier aggregation means that a UE can simultaneously transmit and receive data on two or more component carriers (CCs). For non-aggregated scenarios, data can only be sent and received on the activated BWP of one carrier.

It should be noted that the simultaneous transmission and reception here means that the UE schedules different resource blocks (transport blocks, TB) on different CCs, so that the UE has more scheduling resources.

3. Positioning frequency layer

In NR positioning, a positioning reference signal PRS is introduced for the UE to perform positioning measurement. In order to complete the positioning, the UE needs to measure the PRS sent by the TRPs of multiple cells. Usually, in order to ensure high-precision positioning, the network side will configure a PRS with a larger bandwidth (the larger the PRS bandwidth, the higher the positioning accuracy).

NR positioning also defines the positioning frequency layer. The positioning frequency layer is a set of positioning reference signals (PRS) under a group of TRPs. These PRSs have the same subcarrier spacing, CP type, reference point A (pointA), Bandwidth, comb size. A positioning frequency layer may contain multiple TRPs, each TRP may contain multiple PRS resource sets (resource sets), and each PRS resource set may contain multiple PRS resources (resources). Currently, according to the UE capability, only one PRS of one positioning frequency layer can be processed at the same time.

4. PRS sequence generation and mapping

The PRS sequence is generated by the gold sequence, wherein the generation parameter Cinit is related to the PRS sequence identifier (ID), the symbol index (symbol index) of the PRS, the slot index (slot index), the number of symbols in the time slot, and the like.

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

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

Optionally, in this embodiment of the present application, the at least one target positioning frequency layer is determined by any one of the following: a protocol agreement, configuration information of a network device, and UE customization.

Optionally, in this embodiment of the present application, the above 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, the positioning frequency layer group information is used to indicate at least one positioning frequency layer group, and each positioning frequency layer group includes one or more positioning frequency layers.

It can be understood that in the case where the configuration information includes positioning frequency layer information, the above at least one target positioning frequency layer is at least one positioning frequency layer indicated by the positioning frequency layer information; in the case where the configuration information includes positioning frequency layer group information, the above at least one A target positioning frequency layer is a positioning frequency layer in at least one positioning frequency layer group; when the configuration information includes positioning frequency layer information and positioning frequency layer group information, the above-mentioned at least one target positioning frequency layer includes the information indicated by the positioning frequency layer information.

It should be noted that the simultaneous multiple positioning frequency layers may be understood as: multiple positioning frequency layers with overlapping time domain resources.

Optionally, in this embodiment of the present application, the above-mentioned positioning frequency layer group information may be implicitly configured, that is, multiple positioning frequency layers that are transmitted at the same time are configured, and the multiple positioning frequency layers may be considered as positioning frequency layer groups, but not Embody the concept of positioning frequency layer group. For example, when the network device is configured with multiple positioning frequency layers, and the multiple positioning frequency layers have the same TRP (or TRP list), the same subcarrier spacing (SCS), and simultaneous transmission, the UE may It is assumed that the multiple positioning frequency layers belong to the same positioning frequency layer group, or form the same positioning frequency layer group.

It should be noted that, in this embodiment of the present application, the aggregation process refers to aggregating multiple PRSs in the frequency domain, that is, it is equivalent to a PRS with a larger bandwidth.

In the embodiment of the present application, the UE may perform aggregation processing on the PRS of at least one target positioning frequency layer at the same time, so as to increase the effective bandwidth, thereby improving the positioning accuracy (the larger the PRS bandwidth, the higher the positioning accuracy).

Step 201a1, the UE simultaneously performs aggregation processing on the PRS of some carriers or all carriers of at least one target positioning frequency layer according to the aggregation processing indication information.

In this embodiment of the present application, the aggregation processing indication information in the foregoing step 201a1 is used to instruct the UE to perform aggregation processing on the PRSs of some or all of the carriers in the multiple carriers.

It can be understood that each positioning frequency layer includes at least one carrier; when at least one target positioning frequency layer is a positioning frequency layer and the one positioning frequency layer includes multiple carriers, the UE may The PRSs of some or all of the carriers are aggregated. In the case where 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 may select all the carriers in the multiple positioning frequency layers The PRSs in some or all of the carriers are aggregated.

Optionally, in this embodiment of the present application, the above-mentioned aggregation processing indication information may not be applied to a UE-based positioning scenario, that is, in a UE-based positioning scenario, the UE does not, according to the indication of the aggregation processing indication information, make any changes to the positioning frequency layer. The PRS performs aggregation processing, or in a UE-based positioning scenario, the UE does not expect to be instructed/configured to aggregate processing indication information.

Optionally, in this embodiment of the present application, the above-mentioned 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.

Optionally, in the embodiment of the present application, the above-mentioned first preset condition includes at least one of the following: the SCS of the PRS is the same, the cyclic prefix (CP) type of the PRS is the same, the period of the PRS is the same, and the comb structure of the PRS is the same. The size (comb size) is the same, the target reference point of the PRS is the same, the resource element (RE) level offset (RE offset) of the PRS is the same, the second preset condition is satisfied between any REs where the PRS is located, and the The sequences are mapped according to the first preset mode, the relative RE offsets (relative RE offsets) of the PRSs are the same, the sequence identifiers (IDs) of the PRSs are the same, the time slot numbers of the time slots (slots) where the PRSs are located are the same, and the PRS symbols (symbols) are the same. ) have the same symbol number, the number of symbols in the time slot where the PRS is located is the same, the SFN number of the system frame number (SFN) where the PRS is located is the same, the SFN0 offset between the SFN0 associated with the PRS is 0, and the PRS is associated with the same Spatial transmission filter.

It should be noted that, in the case where the PRS is a periodic signal, the above-mentioned first preset condition may include that the period of the PRS is the same. Any RE where the PRS is located may be understood as: any RE where the PRS of different carriers are located, or any RE where the PRS of different positioning frequency layers are located. For example, the second preset condition is satisfied between any RE where the PRS of carrier 1 is located and any RE where the PRS of carrier 2 is located; or, any RE where the PRS of the positioning frequency layer 1 is located and any RE where the PRS of the positioning frequency layer 2 is located The second preset condition is satisfied between REs.

Optionally, in the embodiment of the present application, the above-mentioned second preset condition is any one of the following: the frequency domain offset between any REs where the PRS is located is an integer multiple of the product of the size of the comb structure and the SCS, where the PRS is located. The number of REs that differ between any REs is an integer multiple of the size of the comb structure.

Optionally, in this embodiment of the present application, any RE where the PRS is located may be the RE with the lowest PRS. It should be noted that the RE with the lowest PRS can be understood as: in the starting physical resource block (physical resource block, PRB) of the PRS, the position of the lowest RE where the PRS is located.

Optionally, in this embodiment of the present application, the first preset condition and the second preset condition are both agreed in a protocol or configured by a network device.

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

It should be noted that the target reference points of the PRS are the same, and may include at least one of the following: the same target reference starting point is used when the sequence of the PRS is generated (when the sequence of the PRS is generated, the target reference point is used as the reference starting point to generate the sequence) , The same target reference starting point is used when mapping the sequence of PRS (that is, when mapping the sequence of PRS, the target reference point is used as the reference starting point to map the sequence), and the starting position of the PRS is the same target reference point as a reference (that is, different The starting position of the PRS takes the target reference point A as a reference).

Optionally, in this embodiment of the present 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) may be greater than 2176.

Optionally, in this embodiment of the present application, the above-mentioned target reference point may be the reference point A.

Optionally, in the embodiment of the present application, the above-mentioned first preset mode is any one of the following: a mode of continuous mapping of PRS sequences/continuous PRS mapping mode, a mode of non-consecutive mapping of PRS sequences/non-consecutive PRS mapping mode.

Optionally, in this embodiment of the present application, the network device may instruct the UE to use a method of continuously mapping PRS sequences or a method of non-continuously mapping PRS sequences.

It should be noted that, during the sequence mapping of PRSs, even if there is a channel spacing between PRSs, the sequences of PRSs are still continuously mapped. Alternatively, in the sequence mapping of the PRS, the sequence of the PRS is non-contiguously mapped, and the sequence position of the corresponding PRS is mapped with the starting PRB of each PRS as the starting point.

Exemplarily, it is assumed that a long PRS sequence is generated, and the PRS long sequence is shared by two PRSs of the positioning frequency layer. The PRSs of the two positioning frequency layers are each composed of PRSs of 100 REs, and the channel spacing between the PRSs is equivalent to 20 REs. This means that the PRSs of the two positioning frequency layers (PRS1 and PRS2) each require a sequence of length 100.

The sequence continuous mapping of the above PRS means that PRS1 and PRS2 use a continuous segment of a long sequence (such as a sequence of consecutive 200 lengths) for mapping, and the interruption caused by the channel interval is not considered during the mapping.

The above sequence non-consecutive mapping of PRS means that PRS1 uses a continuous sequence of a long sequence to map, and PRS2 uses another continuous sequence to map after a sequence with an equivalent channel interval. For example, PRS1 uses a sequence with a continuous length of 100 in a long sequence, and after a sequence of length 20 is separated (considering the influence of channel spacing), PRS2 uses a sequence with a continuous length of 100 for mapping.

It should be noted that the same time slot number of the time slot in which the PRS is located can be understood as: the same slot number or the same slot index in the radio frame. The symbol numbers of the PRS symbols are the same: the symbol number is the same in the slot or the symbol index is the same.

It should be noted that the SFN0 offset of 0 between the SFN0s associated with the PRS can be understood as: the SFN timings (SFN timing) of different PRSs are aligned, that is, synchronous carrier aggregation (CA).

Optionally, in this embodiment of the present application, if the SFN0offset between the SFN0s associated with the PRS is not 0, the UE does not expect to aggregate and process the PRS, for example, the UE does not expect that the SFN timings associated with multiple PRSs are different (SFNs are not synchronized).

Optionally, in this embodiment of the present application, the SFN0offset between the SFN0s associated with the PRSs is an integer multiple of the radio frame length (10ms), so this can also ensure that the slots where the PRSs are located have the same slot number and the same symbol number.

It should be noted that the association of PRSs with the same spatial transmission filter can be understood as: multiple PRSs emit the same beam from the same spatial transmission filter, or the antenna ports corresponding to the multiple PRSs are the same. The same spatial transmission filter associated with the PRS can also be expressed as having the same quasi co-location (QCL) spatial reference signal.

Optionally, in this embodiment of the present application, for at least one target to locate the PRS of some or all of the carriers of the frequency layer, the same target number is used when the PRS of at least two carriers are sequenced or mapped. The target number includes at least one of the following: a symbol number and a time slot number.

Specifically, the time slot number is the time slot index/slot number in one radio frame, and the symbol number is the symbol index/symbol number in one time slot. In other words, for the same symbol, for PRSs located in different positioning frequency layers or PRSs located on different carriers, the UE should assume that multiple PRSs use the same symbol number and/or slot number when generating a sequence or sequence mapping.

Optionally, in this embodiment of the present application, the above-mentioned at least two carriers are determined by any one of the following: protocol agreement, network device indication, and UE self-definition.

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

Optionally, in this embodiment of the present application, the UE may generate a PRS sequence and/or map a PRS sequence according to the SFN timing of the target carrier according to the protocol agreement or the indication information sent by the network device. It can be understood that the network device can instruct the UE to use the SFN timing of a certain carrier as a reference when performing sequence generation and/or mapping of PRSs of multiple carriers (that is, some carriers or all carriers of at least one target positioning frequency layer). , to generate and/or map sequences of these PRSs.

It can be understood that the UE can generate a PRS sequence and/or map a PRS sequence according to the SFN timing of a specific positioning frequency layer or a specific channel bandwidth part, that is, a specific positioning frequency layer can be used as a reference positioning frequency layer, a specific channel bandwidth can be used as a reference positioning frequency layer. part can be used as the reference channel bandwidth part. Wherein, a specific positioning frequency layer or a specific channel bandwidth part is specified by a protocol or a network device.

Optionally, in this 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 and a joint generation manner.

Optionally, in the 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 and a joint mapping manner.

Optionally, in this embodiment of the present application, both the sequence generation mode and the sequence mapping mode of the PRS of the at least one target positioning frequency layer may be specified by a protocol or by a network device.

It can be understood that the UE can determine whether the PRS of at least one target positioning frequency layer independently generates a sequence or whether a sequence is jointly generated, and/or determines whether the PRS of at least one target positioning frequency layer independently maps the sequence according to the protocol agreement or the instruction of the network device. or whether to jointly map the sequence. For example, the sequence generation mode of the PRS of the at least one target positioning frequency layer is an independent generation mode, and the sequence mapping mode of the PRS of the at least one target positioning frequency layer is an independent mapping mode or a joint mapping mode.

It should be noted that the joint generation sequence/joint mapping sequence 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, slot number and/or target reference point (eg reference point A). The independent generation of sequences/maps can be understood as: multiple PRSs use respective reference points, symbol numbers and/or slot numbers.

Optionally, in the embodiment of the present application, the configuration information of the positioning frequency layer includes the configuration of multiple simultaneous carriers, and before processing the PRS of at least one target positioning frequency layer, the UE may also receive the indication information sent by the network device, the The indication information is used to indicate at least one of the following information of multiple carriers: the band indicator where each carrier is located, the relationship between multiple carriers (including in-band non-contiguous carrier aggregation, in-band continuous carrier aggregation) or inter-band carrier aggregation), etc.

The processing method can be directly aggregated large-bandwidth sequence processing, or obtain measurement results (such as TDOA measurement results and other time measurement results) on different positioning frequency layers or carriers respectively, and combine the positioning frequency layers or carriers, or the above two. (For example, aggregation processing is performed on some positioning frequency layers or carriers, and then other positioning frequency layers or carriers are processed separately and then combined).

(2) When the UE processes the PRS of different positioning frequency layers or different carriers, whether to use measurement interval or BWP measurement. For example, the measurement interval (or BWP measurement) is used for all positioning frequency layers or carriers, or the measurement interval is used for some positioning frequency layers or carriers, and the BWP measurement is used for other positioning frequency layers or carriers.

Optionally, in this embodiment of the present application, if the UE uses the BWP to measure the PRS, the measurement result also includes BWP-related configuration, such as at least one of the frequency domain location information of the BWP and the frequency domain location information of the carrier where the BWP is located.

Optionally, in this embodiment of the present application, when the UE processes the PRS of at least one target positioning frequency layer, if the measurement interval is not configured, the UE processes the PRS on the activated BWPs of all activated carriers within the bandwidth of the at least one target positioning frequency layer.

Optionally, in this embodiment of the present application, if the network device instructs aggregation processing, the UE aggregates and processes PRS on the activated BWPs of all activated carriers within the bandwidth of at least one target positioning frequency layer.

Optionally, in this embodiment of the present application, the foregoing step 201a may be specifically implemented by the following step 201a2.

Step 201a2: The UE simultaneously performs aggregation processing on PRSs of some frequency layers or all of the positioning frequency layers in at least one positioning frequency layer group according to the aggregation processing indication information.
