Description

Positioning measurement method, positioning measurement device, terminal and network side equipment

Technical Field

The application belongs to the technical field of mobile communication, and particularly relates to a positioning measurement method, a positioning measurement device, a terminal and network side equipment.

Background

Reduced capability (Reduced Capability, redCap) terminals (also known as User Equipment (UE)) should meet low complexity and cost requirements. The bandwidth characteristics of the RedCap UE are as follows: the method comprises the steps that the RedCAPUE maximally supports 20MHz bandwidth in a first Frequency Range (Frequency Range 1, FR 1); in the second frequency range FR2, the redcap ue supports a maximum of 100MHz bandwidth. The normal UE supports 100MHz at maximum in FR1 and 400MHz at maximum in FR 2.

It can be seen that the bandwidth supported by the redcap UE is much smaller than that of the normal UE. The bandwidth is an important factor affecting the positioning accuracy, and in general, the greater the bandwidth, the higher the positioning accuracy. Therefore, for positioning of the RedCap UE, positioning accuracy obtained by performing positioning measurement under the condition of bandwidth limitation is low.

The positioning measurement method, the positioning measurement device, the terminal and the network side equipment provided by the embodiment of the application are described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 2, the embodiment of the present application provides a positioning measurement method, where the execution body of the method is a terminal, in other words, the method may be performed by software or hardware installed in the terminal, and the terminal may be a RedCap UE. The method comprises the following steps.

S210, the terminal acquires first information, wherein the first information is used for indicating the terminal to measure different sub-bands of the positioning reference signal in a frequency hopping mode at different times.

In order to solve the problem of limited bandwidth of a terminal, the embodiment of the application provides a receiving frequency hopping mode to increase the effective bandwidth of positioning. The reception hopping, i.e. the transmission of the positioning reference signal (Positioning Reference Signal, PRS) 31 with large bandwidth without frequency hopping, is performed with a bandwidth larger than the maximum bandwidth supported by the terminal, and the terminal performs measurement in a frequency hopping manner when performing measurement, i.e. the terminal receives only the sub-band (subband) 32 (also called narrowband, PRS sub-band (prsubband), a partial bandwidth of PRS in the frequency domain, or a partial continuous bandwidth of PRS in the frequency domain) at different times and the frequency domain positions are staggered, as shown in fig. 3. The wideband PRS is divided into several sub-bands of smaller bandwidth for measurement.

The terminal obtains relevant configuration for measuring the PRS in a frequency hopping manner through first information, in one embodiment, the first information includes time-frequency window information of each hop in the frequency hopping manner, each hop corresponds to a time-frequency window, and step S210 includes:

and the time-frequency window corresponding to each hop of the terminal respectively measures different sub-bands of the positioning reference signal or different partial bandwidths of the PRS on the frequency domain. The time-frequency windows corresponding to each hop are not overlapped in the time domain, and can be not overlapped or partially overlapped in the frequency domain.

In one embodiment, the first information further includes at least one of:

the terminal needs the number of sub-bands of the positioning reference signal to be measured;

the number of time-frequency windows;

the number of hops is used for indicating the frequency hopping times of the terminal in the process of measuring the positioning reference signal.

The number of hops N1, the number of time-frequency windows N2, and the number of subbands N3 of the positioning reference signal to be measured may be the same, for example, N may be 2, 4, 8, etc.

Optionally, the first information is determined by at least one of:

indicated by a network-side device, which may be a base station (gNB) corresponding to a serving cell (serving cell) or a location management function (Location Management Function, LMF), such as a network configuration, or a pre-configuration (pre-configuration);

Predefined by or agreed upon by a protocol;

is determined by the terminal selection.

S220, the terminal measures different sub-bands of the positioning reference signal in a frequency hopping mode at different time according to the first information to obtain a measurement result corresponding to the sub-band and/or a measurement result of joint processing of a plurality of sub-bands.

The measurement result of the sub-band may be a measurement result obtained by the terminal measuring the positioning reference signal in a time-frequency window corresponding to the sub-band. Alternatively, the measurement of a subband may be a measurement of each of a plurality of subbands, or a measurement of a portion of the subbands, or an averaged or weighted measurement of a plurality of subbands.

And the measurement result of the joint processing of the plurality of sub-bands is that PRSs of the plurality of sub-bands are spliced (or aggregated), so that the effective bandwidth of the positioning reference signal is improved, and the measurement result with higher precision than that of the non-joint processing is obtained.

According to the technical scheme of the embodiment, the embodiment of the application obtains the measurement result corresponding to the sub-band and/or the measurement result of joint processing of a plurality of sub-bands by obtaining the first information and then measuring different sub-bands of the positioning reference signal in a frequency hopping mode according to the first information at different times, so that the effective bandwidth of the positioning reference signal is equivalently improved, and the positioning accuracy is improved.

Based on the above embodiment, the first information acquired by the terminal includes time-frequency window information of each hop, and the terminal may determine a time-frequency window corresponding to each hop according to the time-frequency window information, that is, determine time domain position information and frequency domain position information corresponding to each hop.

In an implementation manner, the terminal may directly obtain the time-frequency window corresponding to each hop from the time-frequency window information.

Optionally, the time-frequency window information includes information of each time-frequency window. If some parameters corresponding to different time-frequency windows are the same (e.g., bandwidth, duration, starting frequency domain position interval, etc.). In the information of the time-frequency window, the same parameters of the time-frequency windows can be configured only once (for example, as a common configuration of the time-frequency windows, the parameters corresponding to the time-frequency windows are the same), and different parameters (for example, time-frequency window specific parameters) are associated to the corresponding time-frequency windows.

Optionally, the time-frequency window information includes at least one of a first identifier, a second identifier, time-domain position information of the time-frequency window, and frequency-domain position information of the time-frequency window:

the first identifier may identify each time-frequency window, i.e. the time-frequency window identifier, and may also be used to identify each hop, referred to as hop identifier (HopID), because the time-frequency window corresponds to each hop. In the case that the number of the time-frequency windows is N, the first identifier may be simply represented as 0 to N-1. In one embodiment, the first identifiers may be arranged from small to large according to a first ordering rule;

Wherein the first ordering rule includes at least one of:

according to the time sequence of the time frequency windows, namely, a first mark is 0 to represent the time frequency window corresponding to the first hop, and a first mark is N-1 to represent the time frequency window corresponding to the last hop;

according to the sequence from low to high of the frequency domain positions corresponding to the time frequency windows, namely, the first mark is 0 to represent the time frequency window with the lowest frequency domain position, and the first mark is N-1 to represent the time frequency window with the highest frequency domain position.

The second identifier is a partial bandwidth identifier (bwpi) of the partial bandwidth (BandWidthPart, BWP) where the time-frequency window is located, that is, a BWP where the sub-band corresponding to the time-frequency window is located, and the terminal measures the positioning reference signal in the BWP, where in an embodiment, the BWP may be specifically used for positioning the measured BWP.

In one embodiment, each Hop corresponds to one BWP, e.g., the Hop ID may be equivalent to the BWP ID, the time domain location information of the time-frequency window corresponding to each Hop is equivalent to the time domain location information of the BWP, and the frequency domain location of the time-frequency window corresponding to each Hop is equivalent to the frequency domain location information of the BWP.

In one embodiment, each BWP for measuring PRS includes a configuration of time-frequency windows for PRS measurement, and when the BWP is activated to switch to a corresponding BWP, the time-frequency windows for PRS measurement in the BWP are automatically activated, and the UE processes the corresponding PRS in the BWP using the corresponding time-frequency window.

Optionally, the time domain location information of the time frequency window may include at least one of Duration (Duration), period, start time domain location, and repetition configuration.

The duration may be used to indicate a time span of each time-frequency window, and the duration may also be used to indicate a time span occupied by one frequency-hopping measurement, which may be from a time when one frequency-hopping measurement starts to before a start of an adjacent next-hop, or a first time period from a time when one frequency-hopping measurement starts to before a time when an adjacent next-hop starts, which may be a frequency-hopping switching time of the terminal, which may be indicated by a network-side device, predefined protocols, or one of the capabilities of the terminal.

In one embodiment, the duration of the multiple time frequency windows may be the same.

The period is used to represent the period in which the time-frequency window occurs, and in one embodiment, the periods of multiple time-frequency windows may be the same.

The starting time domain position is used to represent a starting time of the time domain position of the time frequency window, and the expression mode of the starting time domain position of the time frequency window can be various and can be based on different time units, for example, a starting subframe (subframe), a starting slot (slot), a starting symbol (symbol) or other starting times.

In one embodiment, the starting time domain position of the time-frequency window may be a time domain offset relative to the first time domain reference point or an absolute time; wherein the first time domain reference point is at least one of the following:

the time domain position of the system frame number 0 (System frame number, sfn 0) of the serving cell, i.e. the time of the time-frequency window is based on the certainty of the serving cell;

a reference signal time difference (Reference Signal Time Difference, RSTD) references the time domain position of the system frame number 0 of the cell, i.e. the time of the time-frequency window is based on the timing of the RSTD reference cell;

a starting time domain position or an ending time domain position of a previous time frequency window, for example, a starting subframe, a starting slot, a starting symbol, etc. of the previous time frequency window;

a starting time domain position or an ending time domain position of the starting time frequency window, namely a starting time domain position or an ending time domain position of the time frequency window corresponding to the first hop;

the starting time domain position of the positioning reference signal, for example, the time domain position where the symbol, slot, subframe, etc. of the first positioning reference signal (or the first positioning reference signal resource, or set of resources) is located. Alternatively, the first positioning reference signal may be the first positioning reference signal in a certain positioning frequency layer.

The absolute time may be a universal coordinated time (Universal Time Coordinated, UTC).

It should be noted that, in the case where there are multiple repetitions of the time-frequency window (or there is a repetition configuration), the start time-domain position or the end time-domain position of the time-frequency window may refer to the start time-domain position or the end time-domain position of each repetition, or refer to the start time-domain position or the end time-domain position after all the repetitions are added up. For example, the starting time domain position or the ending time domain position of the previous time-frequency window may be the starting time domain position or the ending time domain position of a certain repetition of the previous time-frequency window, or may refer to the starting time domain position or the ending time domain position of the previous time-frequency window after all repetitions are added up.

In one embodiment, the time domain offset of each time frequency window is the same with respect to the first time domain reference point, such as: the time domain offset of each time frequency window relative to the starting time domain position or the ending time domain position of the previous time frequency window is the same.

In an embodiment, the time intervals of the starting time domain positions of the adjacent time frequency windows are the same, that is, each time frequency window is set at equal intervals, the terminal may calculate, according to the time interval and the first time domain reference point, the time domain offset of each time frequency window relative to the first time domain reference point to be Y time intervals, where the Y and/or the time intervals may be predefined by the network side device, for example, Y is the same as the time frequency window identifier, and then the terminal may calculate the starting time domain positions of other time frequency windows except the starting time frequency window according to the time frequency window identifier, the starting time domain position of the starting time frequency window, and the time intervals.

The repeated configuration includes at least one of:

In one embodiment, the repeated configuration of each time-frequency window (i.e., the time-frequency windows for which the first identification is different) is the same.

Note that, the corresponding time units of each item of the above-mentioned time domain position information, such as the duration, period, start time domain position, etc., may be set according to actual needs, for example, subframe, slot, symbol, ts, tc, seconds(s), milliseconds (ms), microseconds (us), nanoseconds (ns), etc. Wherein when the time unit is symbol or slot, the associated subcarrier spacing (Subcarrier Spacing, SCS) is consistent with the current BWP of the terminal or indicated by the network side.

In one embodiment, the frequency domain intervals between the starting frequency domain positions of the frequency domain candidate windows or time-frequency domain windows adjacent to the frequency domain are the same.

The initial frequency domain candidate window is a frequency domain candidate window corresponding to the initial time-frequency window.

In an embodiment, the starting frequency domain position of the frequency domain candidate window may take a starting frequency domain position of a frequency domain candidate window with a lowest frequency domain position as a first frequency domain reference point, and take a frequency domain interval as granularity, the terminal may calculate a frequency domain offset of the starting frequency domain position of each frequency domain candidate window relative to the first frequency domain reference point as m×frequency domain interval, where M and/or the frequency domain interval may be predefined by a network side device indication or a protocol, for example, M is the same as the frequency domain candidate window identifier.

In one embodiment, the overlapping bandwidths of the frequency domain candidate windows include:

a first overlap bandwidth for indicating an overlap bandwidth between adjacent frequency domain candidate windows adjacent to and higher than the frequency domain location;

And/or;

and a second overlap bandwidth for indicating an overlap bandwidth between adjacent frequency domain candidate windows adjacent to the frequency domain location and lower.

The frequency domain candidate window information includes the same or similar bandwidth, the starting frequency domain position, the frequency domain interval between the starting frequency domain positions of the frequency domain candidate windows adjacent to the frequency domain, and the overlapping bandwidth, which are the same as or similar to the corresponding part in the frequency domain position information of the time-frequency window in the above embodiment, and the repeated parts are not repeated here.

The fourth identifier is used for identifying frequency domain candidate windows, and in the case that the number of the frequency domain candidate windows is N, the fourth identifier is 0-N-1. In one embodiment, the fourth identification is arranged in order of low to high frequency domain positions of the frequency domain candidate window. The fourth indicator being 0 represents the frequency domain candidate window with the lowest frequency domain position.

In one embodiment, the frequency domain candidate window information is determined by the terminal from a preconfigured or predefined set of frequency domain candidate window information according to the fourth identification. Such as pre-configuring or predefining a plurality of frequency domain candidate windows, the terminal may determine at least one frequency domain candidate window to apply in the frequency hopping measurement based on at least one fourth identification indicated by the network.

A time-frequency window of frequency domain candidate windows is used to measure a segment of subbands of PRS, and in one embodiment, the fourth identity is the same as the identity of the corresponding subband.

Optionally, the frequency domain candidate window information includes information of each frequency domain candidate window. If some parameters corresponding to different frequency domain candidate windows are the same (e.g., duration, repetition configuration, etc.). In the information of the frequency domain candidate window, the same parameters of the plurality of frequency domain candidate windows may be configured only once (e.g., as a common configuration of the plurality of frequency domain candidate windows, the parameters corresponding to the plurality of frequency domain candidate windows are indicated to be the same), and different parameters (e.g., parameters specific to the frequency domain candidate window) may be associated to the corresponding frequency domain candidate window.

In one embodiment, one frequency domain candidate window corresponds to one BWP, which may be dedicated to locating measured BWP.

In one embodiment, the frequency domain position of each frequency domain candidate window is identical to the frequency domain position of the corresponding BWP, and accordingly, the fourth identification of each frequency domain candidate window is identical to the second identification of the corresponding BWP, the frequency hopping sequence of the frequency domain candidate windows is the switching sequence of the BWP, and the starting frequency domain position of the frequency domain candidate window is identical to the starting frequency domain position of the corresponding BWP.

In one embodiment, each BWP for measuring PRS includes a configuration of a frequency domain window for PRS measurement, and after switching to the BWP, a time-frequency window for PRS measurement in the BWP is automatically activated, and the terminal measures PRS based on the time-frequency window.

In one embodiment, the number of time domain candidate windows is the same as the number of frequency domain candidate windows.

The terminal can determine a frequency domain candidate window of a time-frequency window corresponding to each hop in the hopping measurement according to the first hopping sequence, wherein the first hopping sequence is determined by at least one of the following:

a fourth identification of adjacent frequency domain candidate windows;

a frequency hopping sequence list of the frequency domain candidate window;

the protocol is predefined.

In one embodiment, the first frequency hopping sequence may be determined based on a fourth identification of a preceding frequency domain candidate window and/or a fourth identification of a subsequent frequency domain candidate window of the indicated current frequency domain candidate window. Wherein the fourth identification of the previous frequency domain candidate window is used to indicate from which frequency domain candidate window to skip to the current frequency domain candidate window; the fourth identification of the latter frequency-domain candidate window is used to indicate which frequency-domain candidate window to skip from the current frequency-domain candidate window. Alternatively, a fourth identification of a corresponding neighboring frequency domain candidate window may be configured for each frequency domain candidate window, respectively.

In another embodiment, the first hopping sequence may be determined based on a hopping order list indication of a frequency domain candidate window. The frequency hopping sequence list may specifically be an ID list of a fourth identifier, where the sequence of the fourth identifier in the ID list is the frequency hopping sequence of the frequency domain candidate window corresponding to each time-frequency window in the frequency hopping measurement period. Optionally, the length of the IDlist is the number of hops or the number of subbands. The hopping sequence list may further be an information unit sequence arrangement corresponding to each frequency domain candidate window, and the first hopping sequence is determined according to the arrangement sequence.

In another embodiment, the first frequency hopping sequence may be determined based on protocol predefining.

Optionally, the protocol predefining determines the first frequency hopping sequence based on at least one of:

the number of frequency domain candidate windows, the protocol predefines the frequency hopping sequence under the number of different frequency domain candidate windows;

the frequency domain positions of the frequency domain candidate window are in high-low order, for example, in order of low-to-high frequency domain positions or in order of high-to-low frequency domain positions.

Wherein, in the case that the number of frequency domain candidate windows, the number of time domain candidate windows and the number of time frequency windows are the same, the number of frequency domain candidate windows may also be determined or alternatively represented by the number of time domain candidate windows, or the number of time frequency windows.

The first frequency hopping sequence is a relative frequency hopping sequence or an absolute frequency hopping sequence.

The frequency domain candidate window with the absolute frequency hopping sequence of 1 represents a frequency domain candidate window corresponding to a terminal initial time-frequency window; the frequency domain candidate window with order 1 does not represent the frequency domain candidate window corresponding to the starting time frequency window with respect to the frequency hopping sequence, and the frequency hopping measurement may start with the time frequency window corresponding to any frequency domain candidate window and then frequency hop according to the frequency hopping sequence. Alternatively, the terminal may obtain the frequency domain candidate position preceding or following the frequency domain candidate position according to the relative frequency hopping order.

It should be noted that, the frequency domain candidate window corresponding to the initial time-frequency window may also be referred to as an initial frequency domain candidate window.

When the first frequency hopping sequence is a relative frequency hopping sequence, the frequency hopping sequence of the frequency domain candidate window may be a cyclic sequence. For example, 4 frequency domain candidate windows, the identification sequence of the frequency domain candidate window corresponding to the frequency hopping sequence is {0,2,3,1}, if the terminal starts frequency hopping from the frequency domain candidate window identified as 3, the actual frequency hopping sequence is {3,1,0,2}; if the terminal starts hopping from the frequency domain candidate window identified as 1, the actual hopping order is {1,0,2,3}.

In one embodiment, the first hopping sequence is a relative hopping sequence equivalent to an offset indicating the identity of each frequency candidate window relative to the identity of the starting frequency-domain candidate window (or, the frequency-domain position of each hop in the relative hopping sequence is an offset relative to the frequency-domain position of the starting frequency-domain candidate window). Such as: the number of frequency domain candidate windows is N, the identification sequence of the frequency domain candidate window corresponding to the first frequency hopping sequence is { ID list }, the initial frequency domain candidate window is identified as a, and then the actual frequency hopping sequence is (a+ { ID list }) mod N; if the initial frequency-domain candidate window is identified as 2, and the identification sequence of the frequency-domain candidate window corresponding to the first frequency-hopping sequence is {0,1,2,3}, the actual frequency-hopping sequence is {2+ (0, 1,2, 3) } mod 4, i.e., {2,3,0,1}. Or the identification sequence of the frequency domain candidate window corresponding to the first frequency hopping sequence is { ID list }, the frequency domain position of the frequency domain candidate window representing each hop is { ID list } with respect to the frequency domain position of the initial frequency domain candidate window, and B represents the offset of the frequency domain positions of the frequency domain candidate windows adjacent to the frequency domain position; if the initial frequency-domain candidate window is identified as a, the frequency-domain position offset corresponding to the actual frequency-hopping sequence is ((a+ { ID list }) mod N) B, and the actual frequency-domain candidate window is identified as (a+ { ID list }) mod N.

The starting frequency domain candidate window is used to represent the frequency hopping by the terminal starting from the frequency domain candidate window. Optionally, the indication is identified by a frequency domain candidate window.

In one embodiment, when the terminal obtains, through the first information, that the time-frequency window information of each hop includes frequency-domain candidate window information, the frequency-domain candidate window corresponding to the starting time-frequency window is the frequency-domain candidate window closest to the frequency-domain position of the first partial bandwidth, where the first partial bandwidth is the active downlink partial bandwidth (DonwLinkBandWidth Part, DL BWP).

The manner in which the frequency domain candidate window closest to the frequency domain location of the first partial bandwidth is determined may vary, and in one embodiment may be determined based on the following conditions:

A1. selecting a frequency domain candidate window with the largest overlapping range with the first partial bandwidth from frequency domain candidate windows with the overlapping range with the first partial bandwidth as the frequency domain candidate window closest to the frequency domain position of the first partial bandwidth;

A2. if the frequency domain candidate window selected according to A1 is a plurality of frequency domain candidate windows, 1 frequency domain candidate window can be selected randomly from the plurality of frequency domain candidate windows, or the frequency domain candidate window with the lowest or highest frequency domain position is selected from the plurality of frequency domain candidate windows to be used as the frequency domain candidate window closest to the frequency domain position of the first part bandwidth;

A3. If the frequency domain candidate window is not selected according to A1, selecting the frequency domain candidate window with the center frequency point closest to the center frequency point of the first partial bandwidth as the frequency domain candidate window with the nearest frequency domain position of the first partial bandwidth;

A4. if the frequency domain candidate window selected according to A3 is plural, 1 frequency domain candidate window may be randomly selected from the plural frequency domain candidate windows selected, or the frequency domain candidate window with the lowest or highest frequency domain position from the plural frequency domain candidate windows selected may be selected as the frequency domain candidate window closest to the frequency domain position of the first partial bandwidth.

In an embodiment, when the terminal obtains that the time-frequency window information of each hop includes frequency domain candidate window information and time domain candidate window information through the first information, the time-frequency window is determined to carry out frequency hopping measurement by selecting corresponding frequency domain candidate windows from different time domain candidate windows, and the selection of the frequency domain candidate windows is related to the time domain position during frequency hopping measurement. Wherein the time domain position of the frequency hopping measurement is determined by at least one of: time domain candidate window, symbol/slot/subframe/frame (frame)/radio frame (radio frame) corresponding to the time domain position of the frequency hopping measurement, repetition configuration, period, and the like.

In one embodiment, the frequency domain candidate window may be obtained from a time domain position calculation at the time of the frequency hopping measurement, e.g. the fourth identification of the frequency domain candidate window is determined from the third identification of the time domain candidate window.

According to the technical scheme of the embodiment, the time-frequency window corresponding to each hop in the frequency hopping measurement period is obtained, or the time-frequency window corresponding to each hop in the frequency hopping measurement period is determined according to the obtained time-domain candidate window and/or frequency-domain candidate window, so that the time-frequency window can be flexibly configured, the positioning reference signal is measured in each time-frequency window, the effective bandwidth of the positioning reference signal is improved, and the positioning accuracy is improved.

In an embodiment, all frequency domain candidate windows may be activated by default, the terminal may take the starting frequency domain candidate window as a starting point, and perform frequency hopping measurement between all frequency domain candidate windows, for example, the terminal may determine an actual frequency hopping sequence during frequency hopping measurement according to the frequency domain candidate window of the starting time frequency window determined by the second activation information and then combine with a network side device indication or a pre-defined frequency hopping sequence of a protocol.

The second activation information may include a third identifier of the first time domain candidate window, and the terminal determines a frequency domain candidate window corresponding to the initial time-frequency window according to the third identifier of the first time domain candidate window included in the second activation information, and starts to perform frequency hopping measurement.

In one embodiment, the plurality of prsresources are from the same positioning frequency layer. When the terminal performs joint processing on a plurality of time-frequency windows to obtain a joint measurement result, only the same PRSresource part positioned in different time-frequency windows is treated in a joint way.

In one embodiment, in the joint processing of the measurement results corresponding to the positioning reference signal resources in each time-frequency window, the resource unit offset of the positioning reference signal symbols is required to be the same.

In one embodiment, for the same PRSresource, if a terminal cannot obtain a measurement result on a certain time-frequency window, a positioning measurement result reported by the terminal may include measurement results based on other time-frequency windows.
