Description

Configuration method and device of positioning reference signal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring a positioning reference signal.

Background

For Downlink (DL) Positioning Reference Signal (PRS) based on New Radio (NR) system, PRS supports maximum 100M transmission in Frequency Range 1(Frequency Range, FR1) and maximum 400M transmission in Frequency Range 2(Frequency Range, FR 2). The NR PRS Bandwidth configuration is independent of a Bandwidth part (BWP) configuration, and when the PRS Bandwidth is larger than the BWP Bandwidth, a supporting terminal (UE) measures the PRS using a Measurement Gap (Measurement Gap).

In the related art, 2 parameters of a downlink PRS resource repetition factor 'DL-PRS-resource repetition factor' and a downlink PRS resource time interval 'DL-PRS-resource time gap' are introduced, wherein the DL-PRS-resource repetition factor is used for controlling the number of times of repetition of DL PRS resources (resources), and resource IDs of the repeated DL PRS resources are the same. 'DL-PRS-ResourceTimeGap' indicates the interval between 2 repeated DL PRS resources, and the unit is slot, so that the current 'DL-PRS-ResourceTimeGap' defines that the repeated DL PRS resources can only be located on different slots, which limits the repeated DL PRS resources not to be located on the same slot, greatly limits the flexibility of PRS configuration, and also causes great waste of resources.

Additionally, features described with reference to certain examples may be combined in other examples.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network-side device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), or a location server (e.g., an E-SMLC or an lmf (location Manager function)), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication link in the wireless communication system may include an Uplink for carrying Uplink (UL) transmission (e.g., from the terminal 11 to the network side device 12) or a Downlink for carrying Downlink (DL) transmission (e.g., from the network side device 12 to the terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

For Downlink (DL) Positioning Reference Signal (PRS) based on New Radio (NR) system, PRS supports maximum 100M transmission in FR1 and maximum 400M transmission in FR 2. The NR PRS Bandwidth configuration is independent of a Bandwidth part (BWP) configuration, and when the PRS Bandwidth is larger than the BWP Bandwidth, a supporting terminal (UE) measures the PRS using a Measurement Gap (Measurement Gap).

PRS supports beamforming, so that a concept of PRS resource (resource) is introduced, and PRS resource Identification (ID) may correspond to 1 beam of 1 Transmission Reception Point (TRP). The 1 or more PRS resources may form a 1 PRS resource set (set), or 1 or more PRS resources may be included in the 1 PRS resource set. One TRP may contain 1 or more PRS resources. Meanwhile, in order to increase audibility of the UE, PRS beam scanning and PRS beam repetition are supported. In addition, PRS Reference neighbor cell Reference Signals (RSs) are supported as spatial Quasi Co-located (QCL) Reference signals.

The PRS supports a staggered pattern (pattern) and supports flexible pattern configurations. The comb (comb) structure of the PRS resource can support at least {2,4,6 }; the number of symbols (symbol) can support at least {2,4,6 }. Currently, comb structures have not been excluded from {1,8,12 }; the symbol number has not been excluded {1,3,8,12 }.

In the related art, 2 parameters of 'DL-PRS-resource repetition factor' and 'DL-PRS-resource timegap' are introduced, wherein the DL-PRS-resource repetition factor is used for controlling the number of times of DL PRS resource repetition, and the value can be 1,2,4,6,8,16, 32. The resource IDs of the repeated DL PRS resources are the same.

'DL-PRS-ResourceTimeGap' denotes the interval between 2 repeated DL PRS resources, and can take values of 1,2,4,6,8,16,32, in slots. This parameter is only provided to the UE if 'DL-PRS-resource repetition factor' is configured and takes a value greater than 1. The time span of 1 PRS resource set containing repeated DL PRS resources should not exceed the periodicity of the DL PRS.

In order to reduce the interference of inter-cell DL PRS, Long Term Evolution (LTE) introduces a PRS muting (muting) mechanism. When the PRS frequency domain positions of 2 cells are the same, the network side may configure the PRS of one of the neighboring cells to mute (i.e., not send any signal) within a certain period of time, so that the UE may be guaranteed to accurately receive the PRS signal of another cell without being interfered by the inter-cell.

NR redefines the configuration of the mutes, specifically:

the PRS muting can be configured at 'DL PRS resource set' level, can be represented by a bitmap (bitmap), and supports the following options (Option):

option 1: every 1 bit in the bitmap corresponds to 1 or more consecutive periods of DL PRS resource set, whether muted. The 1 st bit may indicate whether 1 or more periods starting from the DL PRS resource set are muted, the 2 nd bit indicates whether 1 or more periods following the DL PRS resource set are muted, and so on. When this bit is set to 0, the UE can consider all DL PRS resources muted during this time.

Option 2: the length of the bitmap is equal to 'DL-PRS-ResourceRepetitionFactor'. A bit in a Bitmap represents whether a resource in a plurality of repeated DL PRS resources is muted or not.

The current 'DL-PRS-resource timegap' defines that the repeated DL PRS resources can only be on different slots, which limits that the repeated DL PRS resources can not be on the same slot, and greatly limits the flexibility of PRS configuration. Meanwhile, considering a special case, when the network configures only 1 resource in the PRS resource set, if the resource is configured to be repeated, according to the current conclusion, the repetition of 1 resource will occupy resources of multiple slots (the number of slots occupied is equal to the retransmission factor), which causes a great waste of resources.

In order to solve the above problem, embodiments of the present invention provide a method and an apparatus for configuring a positioning reference signal, which can improve flexibility of PRS configuration and improve utilization rate of resources.

An embodiment of the present invention provides a method for configuring a positioning reference signal, which is applied to a terminal, and as shown in fig. 2, the method includes:

step 101: acquiring repeated configuration information of a positioning reference signal;

step 102: receiving the positioning reference signal according to the repeated configuration information;

In this embodiment, the offset between two adjacent repeated positioning reference signal resources may be a symbol, so that the repeated downlink positioning reference signal resources may be located in the same time slot, which may enhance coverage of the positioning reference signal, may improve flexibility of downlink positioning reference signal configuration, may also avoid waste of resources, and may improve utilization rate of resources.

The network side device may be a Location server, such as a Location Management Function (LMF) entity, and the network side device may carry the reconfiguration information through LTE Positioning Protocol (LPP) signaling.

The resource identifiers of the repeated N positioning reference signal resources are the same, and N is the repetition times of the positioning reference signal resources indicated by the network side equipment.

When the unit of the offset is a symbol, the value of the offset does not exceed the number of symbols contained in one time slot.

Optionally, the number of symbols or the number of slots of an interval between two adjacent repeated positioning reference signal resources is S, and the offset value is S or S + 1.

If the unit of the offset is a symbol, then

If the repeated y-th positioning reference signal resource is located in the nth time slot, at least one part of the repeated y + x-th positioning reference signal resource derived according to the offset exceeds the range of the nth time slot, y + x is an integer which is greater than 1 and less than or equal to N, x and y are both positive integers, N is the repetition number of the positioning reference signal resource indicated by the network side equipment, and the position of the y + x-th positioning reference signal resource adopts any one of the following rules:

The first symbol of the (y + x) th positioning reference signal resource is the first symbol of the mth time slot;

a first symbol of the (y + x) th positioning reference signal resource is a kth symbol of the m-th time slot, and k is a symbol position of the first symbol of the (y) th positioning reference signal resource configured by the network side device in the nth time slot;

the first symbol of the (y + x) th positioning reference signal resource is the jth symbol of the mth time slot, and j is the symbol position of the starting symbol of the 1 st positioning reference signal resource configured by the network side equipment in the time slot in which the starting symbol is located;

the first symbol of the (y + x) th positioning reference signal resource is the ith symbol of the mth time slot, and i is the symbol position of the first symbol of the (y + x) th positioning reference signal resource derived according to the offset in the mth time slot, for example, the (y + x) th positioning reference signal resource derived according to the offset occupies the 3 rd and 4 th symbols of the mth time slot, and the value of i is 3; more specifically, assuming that the last symbol of the (y + x-1) th repeated positioning reference signal resource is located at the 2 nd last symbol of the nth slot and the offset indicated by the network side is 4 symbols, the 1 st symbol of the (y + x) th repeated positioning reference signal resource is located at the 3 rd symbol of the mth slot, that is, the value of i is 3;

The first symbol of the (y + x) th positioning reference signal resource is the (a) th symbol of the nth time slot, the last symbol of the (y + x) th positioning reference signal resource is the (b) th symbol of the mth time slot, and a and b are the positions of the (y + x) th positioning reference signal resource derived according to the offset. Specifically, assuming that the number of symbols of each slot is 14, the number of symbols of the positioning reference signal is 4, the last symbol of the (y + x-1) th repeated positioning reference resource is located at the 12 th symbol of the nth slot, and the offset indicated by the network side is 2 symbols, then the 1 st symbol of the (y + x) th repeated positioning reference resource is located at the 14 th symbol of the nth slot, and the last 1 symbol is located at the 3 rd symbol of the mth slot.

The first symbol of the positioning reference signal resource may also be referred to as a starting symbol of the positioning reference signal resource. The first symbol of a slot may also be referred to as the starting symbol of the slot.

If y is 1, the repeated y-th positioning reference signal resource is the 1 st positioning reference signal resource. The symbol position of the 1 st positioning reference signal Resource in 1 slot may be determined by a parameter 'DL-PRS-Resource symboloffset' indicated by the network side, where the parameter is used to indicate the position of the starting symbol of the downlink positioning reference signal Resource in the slot (point to starting system of DL PRS Resource with a slot determined by DL-PRS-Resource location offset). The at least a portion of the y + x th positioning reference signal resource exceeding the range of the nth slot includes: one part of the (y + x) th positioning reference signal resource is positioned in the nth time slot, and the other part of the (y + x) th positioning reference signal resource is positioned in the mth time slot; or all of the (y + x) th positioning reference signal resources are located in the mth time slot.

Further, the last symbol of the repeated (y + x-1) th positioning reference signal resource does not exceed the range of the nth time slot.

The above rules may be dictated by protocol definitions or network side equipment.

And the mth time slot is a next time slot containing repeated positioning reference signal resources after the nth time slot, and the mth time slot is adjacent to or not adjacent to the nth time slot. More specifically, when the network side indicates that the duplicate configuration information includes the second indication information, the mth time slot is adjacent to the nth time slot. When the network side indicated repeated configuration information includes the first indication information, the mth time slot may be adjacent or not adjacent.

Optionally, when the duplicate configuration information includes the first indication information, the duplicate configuration information further includes:

third indication information indicating an offset between the mth slot and the nth slot.

Receiving the positioning reference signal according to the repetition configuration information includes:

and if the symbol offset indicated by the first indication information in the repeated configuration information is 0 or an integral multiple of the number of the symbols of the time slot, receiving the positioning reference signal according to the third indication information.

Optionally, the number of time slots between consecutive 2 time slots containing the repeated positioning reference signal resource is R, and the value of the time slot offset is equal to R or R + 1.

If the repeated positioning reference signal resource does not exceed one time slot, the repeated configuration information does not include the third indication information or the value of the time slot offset indicated by the third indication information is 0. Wherein the description may be indicated by a protocol convention or a network side device.

If the repeated configuration information does not include the third indication information, the N repeated positioning reference signal resources are located in a plurality of continuous time slots; or in the same time slot. Wherein the description may be indicated by a protocol convention or a network side device.

Optionally, when the repetition configuration information includes the first indication information, the repetition configuration information does not include the third indication information, and the N repeated positioning reference signal resources are located in consecutive multiple time slots or the same time slot. In other words, the UE does not expect the network side device to configure the first indication information and the third indication information at the same time. Wherein the description may be indicated by a protocol convention or a network side device.

Optionally, the duplicate configuration information further includes:

And fourth indication information indicating a number of repetitions of positioning reference signal resources within one slot N1, where N1 is an integer greater than 0 and less than or equal to N.

In a specific example, none of the N1 repeated positioning reference signal resources within a time slot exceed the time slot.

If the ratio of N to N1 is greater than 1, the number of slots occupied by N repeated positioning reference signal resources is equal to ceil (N/N1).

Optionally, N is an integer multiple of N1.

The above description may be indicated by protocol convention or network side equipment.

Further, in a case that the duplicate configuration information includes second indication information, the duplicate configuration information further includes:

and fifth indication information for indicating an offset between two adjacent repeated positioning reference signal resources.

Optionally, N repeated positioning reference signal resources are all located in the same time slot, where N is the number of times of repetition of the positioning reference signal resources indicated by the network side device.

Wherein the value of the timeslot offset indicated by the repeated configuration information that does not include the third indication information or the third indication information is 0. The above description may be indicated by protocol convention or network side equipment.

The first indication information, the second indication information, the third indication information, the fourth indication information, and the fifth indication information may be indicated by a protocol definition or a network side device.

The resource identifications (DL PRS resource IDs) of the repeated N positioning reference signal resources are the same, where N is the number of times of repetition of the positioning reference signal resources indicated by the network side device.

Optionally, the acquiring the repeated configuration information of the positioning reference signal includes:

and receiving an LPP signaling of the network side equipment, wherein the LPP signaling carries the repeated configuration information.

An embodiment of the present invention further provides a method for configuring a positioning reference signal, which is applied to a network side device, as shown in fig. 3, and includes:

step 201: configuring repeated configuration information of a positioning reference signal for a terminal, wherein the repeated configuration information comprises first indication information or second indication information, the first indication information is used for indicating an offset between two adjacent repeated positioning reference signal resources, and the unit of the offset is a symbol; the second indication information is used for indicating the offset between two adjacent repeated positioning reference signal resources as a time slot or a symbol.

In this embodiment, the offset between two adjacent repeated positioning reference signal resources may be a symbol, so that the repeated downlink positioning reference signal resources may be located on the same time slot, which may enhance coverage of the positioning reference signal, may improve flexibility of downlink positioning reference signal configuration, further avoid waste of resources, and may improve utilization rate of resources.

If the unit of the offset is a symbol, then

the first symbol of the (y + x) th positioning reference signal resource is the first symbol of the m-th time slot;

The first symbol of the (y + x) th positioning reference signal resource is the ith symbol of the mth time slot, and i is the symbol position of the first symbol of the (y + x) th positioning reference signal resource in the mth time slot, which is derived according to the offset, for example, the (y + x) th positioning reference signal resource derived according to the offset occupies the 3 rd and 4 th symbols of the mth time slot, and the value of i is 3; more specifically, assuming that the last symbol of the (y + x-1) th repeated positioning reference signal resource is located at the 2 nd last symbol of the nth time slot, and the offset indicated by the network side is 4 symbols, the 1 st symbol of the (y + x) th repeated positioning reference signal resource is located at the 3 rd symbol of the mth time slot, that is, the value of i is 3;

If y is 1, the repeated y-th positioning reference signal resource is the 1 st positioning reference signal resource. The symbol position of the 1 st positioning reference signal resource in 1 slot may be determined by a parameter 'DL-PRS-ResourceSymbolOffset' indicated by the network side, where the parameter is used to indicate the position of the starting symbol of the downlink positioning reference signal resource in the slot. The at least a portion of the y + x th positioning reference signal resource exceeding the range of the nth slot includes: one part of the (y + x) th positioning reference signal resource is positioned in the nth time slot, and the other part of the (y + x) th positioning reference signal resource is positioned in the mth time slot; or all of the (y + x) th positioning reference signal resources are located in the mth time slot.

Optionally, the duplicate configuration information further includes:

Optionally, N is an integer multiple of N1.

Optionally, in a case that the duplicate configuration information includes second indication information, the duplicate configuration information further includes:

Wherein the value of the timeslot offset indicated by the repeated configuration information that does not include the third indication information or the third indication information is 0.

Optionally, the configuring the repeated configuration information of the positioning reference signal for the terminal includes:

and sending the repeated configuration information to the terminal through LPP signaling.

The technical solution of the present invention is further described below with reference to specific examples.

Example one

In this embodiment, a network side device configures a parameter 'DL-PRS-ResourceRepetitionFactor' to indicate the number of repetitions of DL PRS resource; meanwhile, the network side equipment configures parameters' intra-slot DL-PRS-ResourceTimeGap ' is used to indicate the symbol offset between repeated DL PRS resources, that is, the unit of the parameter ' intra-slot DL-PRS-resource timegap ' is a symbol (symbol) in the first indication information, and the value of the symbol is not more than 1 slot. Specifically, the value of the parameter 'intra-slot DL-PRS-resourcetiegap' may be:

at least one of the above-mentioned (a),

indicating the number of symbols contained in 1 slot. Wherein, the value of 1 indicates that the repeated DL PRS resources are adjacent or spaced by 1 symbol, the value of 2 indicates that the repeated DL PRS resources are adjacent with 1 symbol or spaced by 2 symbols, the value of L indicates that the repeated DL PRS resources are adjacent with L-1 symbol or spaced by L symbols, and so on.

And the DL PRS resource IDs of the repeated DL PRS resources are the same.

Further, the symbol offset between the repeated DL PRS resources may also be expressed as a symbol offset of the repeated DL PRS resources within one slot.

If the repeated xth resource derived by the UE according to the parameters configured by the network side device just crosses the slot boundary, the method includes: the case where part of the resource is in the current slot and part is in the next slot; and in case that all the resources are located in the next slot, the UE shall assume that the xth resource is sent according to any one of the following rules:

(1) starting symbol transmission at the next slot;

(2) transmitting symbols at the same position of the next slot and the first DL PRS resource symbol configured by the network side equipment;

(3) if the xth resource obtained by the UE according to the parameters just completely falls into the next slot, sending the resource according to the deduced position;

(4) if the xth resource obtained by the UE according to the above parameters is just on the slot boundary, that is, a part of the xth resource is in the current slot, and another part is in the next slot, the resource is sent from the starting symbol of the next slot, or the resource is sent from the symbol with the same position as the DL PRS resource symbol configured by the network side device in the next slot.

Wherein x < ═ value of 'DL-PRS-resource repetition factor'. The current slot may or may not be adjacent to the next slot. The current slot and the next slot are two consecutive slots containing repeated positioning reference signal resources.

The rules may be dictated by protocol conventions or by the network side.

Further, the interval between repeated PRS resources in the next slot still follows the indication of the parameter 'intra-slot DL-PRS-resource timegap', and meanwhile, if there is a PRS resource crossing the slot boundary, the PRS resource is still transmitted according to the above rule.

Further, the network side may also configure a parameter 'DL-PRS-resourcetiegap' to indicate an offset between consecutive 2 slots containing the repeated DL PRS resource, that is, third indication information, where the unit of the offset is a slot. The offset value of 1 indicates that 2 continuous slots containing repeated DL PRS resource are adjacent or spaced by 1 slot; the offset value of 2 indicates that 2 continuous slots containing repeated DL PRS resource are adjacent at intervals of 1 slot or adjacent at intervals of 2 slots; the offset value is M, which indicates that continuous 2 slots containing repeated DL PRS resource are adjacent at intervals of M-1 slots or adjacent at intervals of M slots; and so on.

Further, if the repeated PRS resources do not exceed 1 slot, that is, the repeated PRS resources are all located in the same slot, the network side does not configure 'DL-PRS-resource timegap' or configures the value of 'DL-PRS-resource timegap' to be 0. Or, the network side does not configure the 'DL-PRS-resourcetieggap' when configuring the 'intra-slot DL-PRS-resourcetieggap', in other words, the UE does not expect the network side to configure the 'intra-slot DL-PRS-resourcetieggap' and the 'DL-PRS-resourcetieggap' at the same time.

In a specific example, if the plurality of repeated DL PRS resources exceeds 1 slot, consecutive slots containing the repeated DL PRS resources are adjacent.

Example two

In this embodiment, the repeated PRS resources do not exceed 1 slot, that is, the repeated PRS resources are all located in the same slot. The last 1 symbol of the repeated Nth PRS resource obtained by the UE according to the parameters configured by the network side does not exceed the boundary of the slot, namely the index of the last 1 symbol of the Nth PRS resource does not exceed the boundary of the slot

The index is a symbol index in a time slot, wherein N is a value of 'DL-PRS-resource repetition factor'.

Further, the network side can configure 'DL-PRS-resource timegap' to be 0. Or the network side does not configure the 'DL-PRS-ResourceTimeGap' when configuring the 'intra-slot DL-PRS-ResourceTimeGap'. In other words, the UE does not expect the network to configure 'intra-slot DL-PRS-resource timegap' and 'DL-PRS-resource timegap' at the same time.

If the last 1 symbol of the repeated Nth resource obtained by the UE according to the parameters configured by the network does not exceed the slot boundary, then:

for comb-2 resources, the value of 'DL-PRS-resource repetition factor' may be: 1,2,3 … 7.

For comb-4 resources, the value of 'DL-PRS-resource repetition factor' may be: 1,2,3.

For comb-6 resources, the value of 'DL-PRS-resource repetition factor' may be: 1,2.

For comb-12 resources, the value of 'DL-PRS-resource repetition factor' may be: 1.

thus, the value of 'DL-PRS-resource repetition factor' may comprise: 3,5, 7.

EXAMPLE III

In this embodiment, the network side device further configures a parameter 'intra-slot DL-PRS-resource repetition factor' for indicating the number of times that the DL PRS resource repeats in one slot, that is, the fourth indication information.

Further, the UE obtains the last 1 symbol of the PRS resource repeated in 1 slot according to the parameters 'intra-slot DL-PRS-resource timegap' and 'intra-slot DL-PRS-resource repetition factor' configured on the network side, so as not to exceed the boundary of the slot.

Further, the value of 'intra-slot DL-PRS-resource repetition factor' is a factor of 'DL-PRS-resource repetition factor', or 'DL-PRS-resource repetition factor' is an integer multiple of 'intra-slot DL-PRS-resource repetition factor'.

Further, the network side may configure a parameter 'DL-PRS-resourcetiegap' at the same time to indicate an offset between 2 consecutive slots containing repeated DL PRS resource, and the network side configures the parameter only when a ratio of 'DL-PRS-ResourceRepetitionFactor' to 'intra-slot DL-PRS-ResourceRepetitionFactor' is greater than 1. The network side may not directly indicate the 'inter-slot DL-PRS-resource repetition factor' of the PRS resource in the slot, and the UE may calculate the 'inter-slot DL-PRS-resource repetition factor' of the PRS resource in the slot according to the parameter 'DL-PRS-resource repetition factor' configured by the network side and the 'intra-slot DL-PRS-resource repetition factor', and the calculation formula is:

inter-slot DL-PRS-ResourceRepetitionFactor＝DL-PRS-ResourceRepetitionFactor/intra-slot DL-PRS-ResourceRepetitionFactor。

in a specific example, the network side does not explicitly indicate the parameter 'DL-PRS-ResourceRepetitionFactor', but indicates the parameters 'intra-slot DL-PRS-ResourceRepetitionFactor' and 'inter-slot DL-PRS-ResourceRepetitionFactor'. The UE calculates the total repetition times of DL PRS resource according to the parameters 'inter-slot DL-PRS-resource repetition factor' and 'intra-slot DL-PRS-resource repetition factor' configured on the network side, and the calculation formula is as follows:

DL-PRS-ResourceRepetitionFactor＝inter-slotDL-PRS-ResourceRepetitionFac tor*intra-slot DL-PRS-ResourceRepetitionFactor

Further, the network side may also configure a multicasting bitmap, where the multicasting bitmap may also indicate one of the following:

(1) the length of the Bitmap is equal to 'intra-slot repetition factor', and when each bit of the Bitmap corresponds to DL PRS resource and repeats in a slot, the repetition index in the slot is obtained.

(2) The length of the Bitmap is equal to 'inter-slot repetition factor', and when each bit of the Bitmap corresponds to DL PRS resource and repeats in slots, the repetition index in the slots is obtained.

(3) The 'intra-slot DL-PRS-resource repetition factor' configured on the network side can be at least one of 1,2,3,4,5,6 and 7.

Example four

In this embodiment, the network side configures a parameter 'repetition type', which is used to indicate whether a unit of the parameter 'DL-PRS-resourcetiegap' is 'slot' or 'symbol', and the size is 1bit, and corresponds to the second indication information, and the 'DL-PRS-resourcetiegap' corresponds to the fifth indication information. If the 'repetition type' is configured to be 'true (1)', indicating that the unit of 'DL-PRS-ResourceTimeGap' is slot; if the configuration 'repetition type' is 'false (0)', the unit of 'DL-PRS-resource timegap' is indicated to be symbol. Alternatively, the reverse is also possible.

Further, if the 'repetition type' indicates that the unit of 'DL-PRS-resource timegap' is 'symbol':

the value of 'DL-PRS-resource timegap' does not exceed the number of symbols contained in 1 slot. Specifically, the value of the parameter 'intra-slot DL-PRS-resourcetiegap' may be:

at least one of the above-mentioned (a),

indicating the number of symbols contained in 1 slot. Wherein, the value of 1 represents that the repeated DL PRS resources are adjacent or separated by 1 symbol, the value of 2 represents that the repeated DL PRS resources are adjacent or separated by 1 symbol, and the value of 2 represents that the repeated DL PRS resources are adjacent or separated by 2 symbolsL denotes repeated DL PRS resource is adjacent with an interval of L-1 symbols or L symbols, and so on.

(1) starting symbol transmission at the next slot;

Wherein, x < ═ is the value of 'DL-PRS-resource repetition factor'. The current slot may or may not be adjacent to the next slot. The current slot and the next slot are two consecutive slots containing repeated positioning reference signal resources.

The rules may be dictated by protocol conventions or by the network side.

In a specific example, the last 1 symbol of the repeated nth PRS resource obtained by the UE according to the parameters configured on the network side may not exceed the boundary of the slot, that is, when the unit of 'DL-PRS-resource timegap' is limited to symbol, the repeated N PRS resources are repeated only within 1 slot.

Wherein N is the value of DL-PRS-resource repetition factor,

alternatively, the value range of 'DL-PRS-resource repetition factor' may be extended to {1,2,3,4,5,6,7,8,16,32 }.

The value range of 'DL-PRS-resource timegap' can be extended to {1,2,3,4,5,6,7,8,16,32 }.
