Background technique

Reduced Capability (RedCap) terminals (also known as User Equipment (UE)) should meet low complexity and cost requirements. The bandwidth characteristics of RedCap UE are as follows: in the first frequency band range (Frequency Range 1, FR1), RedCap UE supports a maximum bandwidth of 20 MHz (Mega Hertz, MHz); in the second frequency band range FR2, RedCap UE supports a maximum bandwidth of 100MHz.

In other words, the method can be executed by software or hardware installed on the terminal, and the terminal can be a RedCap UE. The method includes the following steps.

S210. The terminal obtains the first information.

The first information is used to instruct the terminal to measure different subbands of the positioning reference signal in a frequency hopping manner at different times.

In order to solve the problem of limited terminal bandwidth, embodiments of this application propose a receiving frequency hopping method to increase the effective bandwidth of positioning. The reception frequency hopping means that the positioning reference signal (Positioning Reference Signal, PRS) 31 is sent without frequency hopping and is sent with a large bandwidth. The bandwidth is greater than the maximum bandwidth supported by the terminal. The terminal uses frequency hopping when measuring. , that is, the terminal only receives subband 32 (also called narrowband, PRS subband), part of the bandwidth of PRS in the frequency domain, or part of the continuous bandwidth of PRS in the frequency domain at different times. And the frequency domain positions are staggered, as shown in Figure 3. The wideband PRS is divided into several sub-bands with smaller bandwidths for measurement.

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

The number of time-frequency windows;

The number of hops is used to indicate the number of times the terminal needs to perform frequency hopping during the measurement of 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 as N. For example, N may be 2, 4, 8, etc.

S220. The terminal uses frequency hopping to measure different subbands of the positioning reference signal at different times according to the first information, and obtains measurement results corresponding to the subbands and/or measurement results of joint processing of multiple subbands.

The measurement result of the subband may be a measurement result obtained by the terminal measuring the positioning reference signal in a time-frequency window corresponding to the subband. Optionally, the measurement results of the subbands may be the measurement results of each subband among multiple subbands, or the measurement results of part of the subbands, or the averaged or weighted measurement results of multiple subbands.

The measurement results of the joint processing of multiple subbands are obtained by splicing (or aggregating) the PRS of multiple subbands to increase the effective bandwidth of the positioning reference signal and obtain measurement results with higher accuracy than non-joint processing.

Parameters (such as time-frequency window-specific parameters) are associated with the corresponding time-frequency window.

In one embodiment, the BWP may be exclusively used for positioning measurement BWP.

In one implementation, each hop corresponds to a BWP. For example, the Hop ID can 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. Each hop ID can be equivalent to the BWP ID. The frequency domain position of the time-frequency window corresponding to the hop is equivalent to the frequency domain position information of the BWP.

In one implementation, each BWP used for measuring PRS contains the configuration of the time-frequency window for PRS measurement. When the activated BWP is switched to the corresponding BWP, the time-frequency window for PRS measurement in the BWP is automatically activated. The UE The corresponding time-frequency window is applied within the BWP to process the corresponding PRS.

Optionally, the time domain location information of the time-frequency window may include at least one of duration, period, starting time domain location, and repeat configuration.

In one implementation, the starting frequency domain position is the starting frequency domain position of the positioning reference signal, for example, the starting frequency domain position of the positioning frequency layer currently measured by the UE, such as the starting frequency domain position of the starting physical resource block. domain location.

The starting frequency domain position of the positioning reference signal, such as the starting frequency domain position of the currently measured positioning frequency layer;

The frequency domain position of the reference point A corresponding to the positioning reference signal, such as the frequency domain position of the reference point A of the currently measured positioning frequency layer;

The starting frequency domain position of the frequency domain candidate window with the highest frequency domain position

The starting frequency domain position or the highest frequency domain position of the starting frequency domain candidate window;

The starting frequency domain position or the highest frequency domain position of the frequency domain candidate window adjacent to the frequency domain.

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

It should be noted that the starting frequency domain candidate window is a frequency domain candidate window corresponding to the starting time-frequency window.

In one implementation, the starting frequency domain position of the frequency domain candidate window can be the starting frequency domain position of the frequency domain candidate window with the lowest frequency domain position as the first frequency domain reference point, and the frequency domain interval as the granularity , the terminal can calculate the 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, and the M and/or frequency domain interval can be determined by the network Side device indication or protocol pre-definition, for example, M is the same as the frequency domain candidate window identifier.

In one implementation, the overlapping bandwidth of the frequency domain candidate window includes:

The first overlapping bandwidth is used to indicate the overlapping bandwidth between adjacent frequency domain candidate windows that are adjacent to and higher than the frequency domain position;

and / or;

The second overlapping bandwidth is used to indicate the overlapping bandwidth between adjacent frequency domain candidate windows that are adjacent to and lower than the frequency domain position.

The frequency domain candidate window information includes bandwidth, starting frequency domain position, frequency domain adjacent frequency domain candidates The frequency domain interval and overlap bandwidth between the starting frequency domain positions of the window are the same as or similar to the corresponding parts in the frequency domain position information of the time-frequency window in the above embodiment, and the repeated parts will not be described again here.

The fourth identifier is used to identify frequency domain candidate windows. When the number of frequency domain candidate windows is N, the fourth identifier ranges from 0 to N-1. In one implementation, the fourth identifiers are arranged from small to large in the order of frequency domain positions of the frequency domain candidate windows from low to high. The fourth identifier of 0 indicates the frequency domain candidate window with the lowest frequency domain position.

In one implementation, the frequency domain candidate window information is determined by the terminal from a preconfigured or predefined frequency domain candidate window information set according to the fourth identifier. For example, if multiple frequency domain candidate windows are preconfigured or predefined, the terminal can determine at least one frequency domain candidate window to be applied during frequency hopping measurement according to at least one fourth identifier indicated by the network.

A time-frequency window composed of a frequency domain candidate window is used to measure a sub-band of the PRS. In one implementation, the fourth identifier is the same as the identifier of the corresponding sub-band.

Optionally, the frequency domain candidate window information includes information about each frequency domain candidate window. If some parameters corresponding to different frequency domain candidate windows are the same (such as duration, repeat configuration, etc.). In the information of frequency domain candidate windows, the same parameters of multiple frequency domain candidate windows can be configured only once (for example, as a common configuration of multiple frequency domain candidate windows, it means that these parameters corresponding to multiple frequency domain candidate windows are the same), And associate different parameters (such as parameters specific to the frequency domain candidate window) to the corresponding frequency domain candidate window.

In one embodiment, one frequency domain candidate window corresponds to one BWP, which may be specifically used to locate the measured BWP.

In one implementation, the frequency domain position of each frequency domain candidate window is the same as the frequency domain position of the corresponding BWP. Correspondingly, the fourth identifier of each frequency domain candidate window is the same as the second identifier of the corresponding BWP, The frequency hopping sequence of the frequency domain candidate window is the switching sequence of the BWP, and the starting frequency domain position of the frequency domain candidate window is the same as the starting frequency domain position of the corresponding BWP.

In one implementation, each BWP used for measuring PRS contains the configuration of the frequency domain window for PRS measurement. After switching to the BWP, the time-frequency window for PRS measurement in the BWP is automatically activated. The terminal is based on this time. Frequency window to measure PRS.

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

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

The fourth identifier of the adjacent frequency domain candidate window;

The frequency hopping order list of the frequency domain candidate window;

Protocol predefined.

In one implementation, the first frequency hopping sequence may be determined based on a fourth identifier of a previous frequency domain candidate window and/or a fourth identifier of a subsequent frequency domain candidate window of the indicated current frequency domain candidate window. Among them, the fourth identifier of the previous frequency domain candidate window is used to indicate which frequency domain candidate window to jump from to the current frequency domain candidate window; the fourth identifier of the subsequent frequency domain candidate window is used to indicate which frequency domain candidate window to jump from. Which frequency domain candidate window. Optionally, each frequency domain candidate window may be configured with a corresponding fourth identifier of an adjacent frequency domain candidate window.

In another implementation manner, the first frequency hopping sequence may be determined based on a frequency hopping order list indication of the frequency domain candidate window. The frequency hopping sequence list may specifically be an ID list (list) of fourth identifiers, and the order of the fourth identifiers in the ID list is the frequency hopping sequence of the frequency domain candidate windows corresponding to each time-frequency window during the frequency hopping measurement. Optionally, the length of the ID list is the number of hops or the number of subbands. The frequency hopping order list may also be a sequential arrangement of information units corresponding to each frequency domain candidate window, and the first frequency hopping sequence is determined according to the arrangement order.

In another implementation manner, the first frequency hopping sequence may be determined based on protocol predefinition.

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

The number of frequency domain candidate windows. The protocol predefines the frequency hopping order under different numbers of frequency domain candidate windows;

The frequency domain positions of the frequency domain candidate windows are in high and low order, for example, in the order of frequency domain positions from low to high or from high to low.

Wherein, when 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 can also be determined by the number of time domain candidate windows, or the number of time-frequency windows. Quantity indicates confirmation or replacement expression.

It should be noted that the first frequency hopping sequence is a relative frequency hopping sequence or an absolute frequency hopping sequence.

Among them, in the absolute frequency hopping order, the frequency domain candidate window with order 1 represents the frequency domain candidate window corresponding to the terminal's starting time-frequency window; with respect to the frequency hopping order, the frequency domain candidate window with order 1 does not represent the starting time-frequency window. The corresponding frequency domain candidate window, and the frequency hopping measurement can start from the time-frequency window corresponding to any frequency domain candidate window, and then perform frequency hopping according to the frequency hopping sequence. Alternatively, according to the relative frequency hopping order, the terminal can obtain the frequency domain candidate position before or after the frequency domain candidate position.

It should be noted that the frequency domain candidate window corresponding to the starting time-frequency window can also be called the starting frequency domain candidate window.

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

In one implementation, the first frequency hopping sequence is a relative frequency hopping sequence, and the relative frequency hopping sequence is equivalent to indicating an offset of the identifier of each frequency candidate window relative to the identifier of the starting frequency domain candidate window. (In other words, the frequency domain position of each hop in the relative frequency hopping sequence is the frequency domain position relative to the starting frequency domain candidate window. offset). For example: 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}, and the starting frequency domain candidate window identification is a, then the actual frequency hopping sequence is (a+{ID list}) mod N; If the starting frequency domain candidate window identifier is 2, and the identifier sequence of the frequency domain candidate window corresponding to the first frequency hopping sequence is {0,1,2,3}, then the actual frequency hopping sequence is {2 +(0,1,2,3)}mod 4, that is {2,3,0,1}. Alternatively, the identification sequence of the frequency domain candidate window corresponding to the first frequency hopping sequence is {ID list}, indicating that the frequency domain position of the frequency domain candidate window of each hop relative to the frequency domain position of the starting frequency domain candidate window is {ID list }*B, B represents the frequency domain position offset of the frequency domain candidate window adjacent to the frequency domain position; if the starting frequency domain candidate window is identified as a, then the frequency domain position offset corresponding to the actual frequency hopping sequence is (( a+{ID list})mod N)*B, the actual frequency domain candidate window identification sequence is (a+{ID list})mod N.

The starting frequency domain candidate window is used to indicate that the terminal starts frequency hopping from this frequency domain candidate window. Optionally, indicate through the frequency domain candidate window identifier.

In one embodiment, when the time-frequency window information of each hop obtained by the terminal through the first information includes frequency domain candidate window information, the frequency domain candidate window corresponding to the starting time-frequency window is the same as the first part of the bandwidth. The frequency domain candidate window with the closest frequency domain position, the first part of the bandwidth is the active downlink part bandwidth (DonwLink BandWidth Part, DL BWP).

The frequency domain candidate window closest to the frequency domain position of the first part of the bandwidth can be determined in various ways. In one implementation, the determination can be based on the following conditions:

A1. Select from the frequency domain candidate windows that overlap with the first part of the bandwidth, and use the frequency domain candidate window with the largest overlap range with the first part of the bandwidth as the frequency domain candidate window closest to the frequency domain position of the first part of the bandwidth;

A2. If there are multiple frequency domain candidate windows selected based on A1, you can randomly select one from the multiple selected frequency domain candidate windows, or select a frequency domain position from the multiple selected frequency domain candidate windows. The lowest or highest frequency domain candidate window is used as the frequency domain candidate window closest to the frequency domain position of the first part of the bandwidth;

A3. If no frequency domain candidate window is selected based on A1, select the frequency domain candidate window whose center frequency point is closest to the center frequency point of the first part of the bandwidth as the frequency domain candidate window closest to the frequency domain position of the first part of the bandwidth;

A4. If there are multiple frequency domain candidate windows selected according to A3, you can randomly select one from the multiple selected frequency domain candidate windows, or select a frequency domain position from the multiple selected frequency domain candidate windows. The lowest or highest frequency domain candidate window is used as the frequency domain candidate window closest to the frequency domain position of the first part of the bandwidth.

In one implementation, when the time-frequency window information of each hop obtained by the terminal through the first information includes frequency domain candidate window information and time domain candidate window information, the corresponding time domain candidate window can be selected using different time domain candidate windows. The frequency domain candidate window is used to determine the time-frequency window for frequency hopping measurement, and the selection of the frequency domain candidate window is related to the time domain position during frequency hopping measurement. Wherein, the time domain position of the frequency hopping measurement is from the following to Determine one of the following: the time domain candidate window, the symbol/slot/subframe/frame/radio frame corresponding to the time domain position of the frequency hopping measurement, repeated configuration, period, etc.

In one implementation, the frequency domain candidate window can be calculated based on the time domain position during frequency hopping measurement. For example, the fourth identifier of the frequency domain candidate window is determined according to the third identifier of the time domain candidate window.
