[0040] The following explanations and descriptions are provided for some concepts and / or terms involved in the PRS measurement method, apparatus, UE, and network-side equipment provided in the embodiments of this application.

[0041] 1. PRS

[0042] Currently, the NR downlink positioning reference signal (DL PRS) in the NR positioning system, hereinafter referred to as NR PRS, is used by the UE for positioning measurement.

[0043] It should be noted that in order to complete the positioning, the UE needs to measure the PRS transmitted by multiple cells, such as NR PRS.

[0044] The basic characteristics of PRS are as follows:

[0045] 1) PRS supports transmission up to 100M in frequency range (FR) 1 and up to 400M in FR 2.

[0046] The bandwidth configuration of the NR PRS is independent of the UE's BWP configuration. When the PRS bandwidth is greater than the bandwidth of the BWP, the UE can use the MG to measure the PRS.

[0047] 2) PRS supports beamforming, therefore the concept of PRS resource is introduced, specifically:

[0048] The identifier of a PRS resource can correspond to one beam in a TRP.

[0049] One or more PRS resources can form a PRS resource set, or a PRS resource set can contain one or more PRS resources. A TRP can contain one or more PRS resources.

[0050] Meanwhile, to enhance the audibility of the UE, PRS beam scanning and PRS beam repetition are supported.

[0051] In addition, it supports remote sensing (RS) of PRS reference neighboring cells as a spatial quasi-location (QCL) reference signal.

[0052] 2. Posing Frequency Layer (PFL): A PFL is a set of PRS resources that are one or span multiple TRPs and have the same Separate-Channel Signaling (SCS), Cyclic Prefix (CP) type, point A, PRS bandwidth, and starting Physical Resource Block (PRB) location.

[0053] 3. MG used in positioning

[0054] In the NR positioning system, PRS was introduced for UE to perform positioning measurements.

[0055] To complete a location determination, the UE needs to measure the PRS transmitted by multiple cells. Typically, to ensure high-accuracy positioning, the network-side equipment / network side configures a large-bandwidth PRS (generally, the larger the PRS bandwidth, the higher the positioning accuracy). However, a large-bandwidth PRS can sometimes exceed the range of the UE's currently active BWP. Therefore, for UE measurement, a MG (Measuring Camera) is used to measure the PRS beyond the range of the UE's active BWP.

[0056] Specifically, since the PRS configuration information is directly sent to the UE by the location server via LTE Positioning Protocol (LPP) signaling, the serving NR Node B (gNB) does not know the specific configuration information of the PRS sent by neighboring cells, including the time-domain location and frequency-domain location of the PRS sent by neighboring cells. Therefore, when the UE needs to use the MG to measure the PRS, it first needs to request the MG from the serving gNB via an MG request message. This request signaling carries the configuration information of the MG that the UE expects (such as MG period, MG length, MG period offset, and frequency point information of the positing frequency layer associated with the MG). Then, the serving gNB decides how to configure the MG and subsequently sends the MG configuration information to the UE, so that the UE can use the MG configured by the serving gNB to measure the PRS.

[0057] It should be noted that if the MG is not configured, the UE is not required to use the MG to measure PRS.

[0058] The following is a brief description of the configuration of the MG used for positioning measurement and the procedure for measuring the positioning reference signal PRS:

[0059] Step 1: The Location Management Function (LMF) in the location server sends the PRS configuration information (i.e., location assistance data) to the UE, so that the UE can obtain the location assistance data.

[0060] Step 2: The LMF sends a location measurement request message to the UE, so that the UE can receive the location measurement request message.

[0061] Step 3: After receiving the location measurement request message, the UE can request the serving gNB to measure PRS in the MG through the MG request message.

[0062] Step 4: The serving gNB configures the appropriate MG to the UE and sends the MG configuration information to the UE.

[0063] Step 5: The UE receives the configuration information of the MG and performs PRS measurement in the configured MG according to the configuration information.

[0064] In summary, the UE can only send an MG request message to the serving gNB to request an MG after receiving the PRS configuration information and location measurement request message from the LMF; furthermore, it can only perform PRS measurements in the MG configured by the serving gNB after receiving the MG configuration information from the serving gNB. However, the time delay between the UE sending the MG request message and receiving the MG configuration information is approximately 20ms, meaning the UE's MG request delay is relatively long. This results in a long delay for the UE to measure PRS.

[0065] In addition, the mismatch between the MG period and PRS will cause the PRS measurement period to be extended, further increasing the latency of UE PRS measurement.

[0066] 4. PRS Processing Window

[0067] To reduce latency in UE PRS measurement, a MG-less scheme is proposed. This means that the UE can measure PRS outside of the MG, specifically within the UE's active DL BWP. This reduces the latency of the UE requesting the MG and increases the efficiency of PRS measurement and data scheduling.

[0068] Specifically, in order to ensure latency (i.e., the UE does not process other signals / channels at the same time while processing PRS), a PRS processing window is further introduced. That is, when the UE measures PRS in active DL BWP, it needs to measure based on the PRS processing window.

[0069] Optionally, within the PRS processing window, if the UE determines that the PRS has a higher priority, then the UE will prioritize processing the PRS and interrupt the transmission of other corresponding signals or channels. For example, during the entire duration of the PRS processing window or at the location of the PRS symbol (depending on the UE capability), if the UE determines that the PRS has a higher priority, then the transmission of at least one of the following: all component carriers (CCs), the CCs associated with the PRS, and other downlink signals / channels associated with the PRS in the same frequency band.

[0070] Optionally, the PRS processing window can currently be configured and indicated via the service gNB, which can also be referred to as the display activation of the PRS processing window; the configuration and indication of the PRS processing window at least supports RRC (pre-configured) configuration and MAC CE activation.

[0071] Currently, explicit activation of the PRS Processing window is supported, for example through the Medium Access Control (MAC CE), and other activation methods have not been excluded. The PRS measurement method provided in this application presents a scheme for implicitly activating (or automatically activating) the PRS processing window and / or MG. Compared with explicit activation, implicit activation (or automatic activation) can further reduce signaling overhead.

[0072] The PRS measurement method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0073] This application provides a PRS measurement method. Figure 2 A flowchart of a PRS measurement method provided in an embodiment of this application is shown. Figure 2 As shown, the PRS measurement method provided in this application embodiment may include the following steps 201 and 202.

[0074] Step 201: UE obtains activation information.

[0075] In this embodiment of the application, the UE can obtain activation information when performing PRS measurement as required, so as to determine whether the target object expected by the UE is activated through the activation information.

[0076] Optionally, in this embodiment of the application, the activation information may be pre-configured, pre-defined, protocol-agreed, or sent by other devices.

[0077] Optionally, in this embodiment of the application, the activation information may be sent by a first network-side device. The first network-side device may be a serving gNB.

[0078] Step 202: The UE determines whether the target object is activated based on the activation information.

[0079] In this context, when the target object is activated, the target object is used for PRS measurement.

[0080] Optionally, in the embodiments of this application, the target object may include at least one of the following: a target PRS processing window, a target measurement interval MG.

[0081] In this embodiment of the application, the target PRS processing window is used to perform PRS measurements outside the MG, or to perform PRS measurements when the MG is not configured / inactive.

[0082] Optionally, in the embodiments of this application, the target MG corresponds to at least one (pre-)configured MG; the target PRS processing window corresponds to at least one (pre-)configured PRS processing window.

[0083] In this embodiment of the application, when the target object includes a target PRS processing window, the number of target PRS processing windows in the target object is not limited, that is, the target object may include one or more target PRS processing windows; similarly, when the target object includes a target MG processing window, the number of target MGs in the target object is not limited, that is, the target object may include one or more target MGs.

[0084] Optionally, in this embodiment of the application, the target object can be used to measure the PRS of a bandwidth that exceeds the range of the UE's active BWP.

[0085] The PRS measurement method provided in this application will be described in detail below, taking the first and second implementation methods as examples.

[0086] The first implementation method: The activation information obtained by the UE includes activation conditions.

[0087] Optionally, in this embodiment, the activation information includes activation conditions, and the target object includes at least the target PRS processing window. Step 202 described above can be specifically implemented through step 202a as follows.

[0088] Step 202a: If the UE meets the activation conditions, the UE determines that the target PRS processing window is activated and expects to perform PRS measurement within the target PRS processing window.

[0089] Optionally, in this embodiment of the application, after the UE obtains the activation condition, it can first determine whether the UE meets the activation condition. If it is determined that the activation condition is met, the UE can determine / assume that the target PRS processing window in the target object is activated; if it is determined that the target condition is not met, the UE can determine that the target PRS processing window in the target object is not activated.

[0090] It is worth noting that in this invention, 'UE determination' can also be replaced by 'UE assumptions' or 'UE isassumed' or 'UE expects'.

[0091] It should be noted that the target object is related to the activation conditions and the PFL pre-configured for the UE by the network.

[0092] Optionally, in this embodiment of the application, when the UE meets the activation conditions, the UE may determine that all PRS processing windows corresponding to the UE are activated, or determine that at least one PRS processing window corresponding to the UE is activated.

[0093] Optionally, in the embodiments of this application, the activation condition may include a first activation condition; or, the activation condition may include one of a second activation condition and a third activation condition.

[0094] In this embodiment, the first activation condition applies to scenarios where the activation behavior of all PRS processing windows corresponding to the UE is consistent. That is, all PRS processing windows corresponding to the UE are either all activated or all deactivated simultaneously.

[0095] In this embodiment, the second and third activation conditions apply to scenarios where the activation behavior of different PRS processing windows corresponding to the UE can be different. That is, a portion of the PRS processing windows corresponding to the UE can be activated, while another portion of the PRS processing windows corresponding to the UE is inactive.

[0096] Here, the terminal determines the activation of the PRS processing window based on the activation conditions, which can also be called 'implicit activation of the PRS processing window' or 'automatic activation of the PRS processing window'.

[0097] Optionally, the first activation condition in the embodiments of this application includes at least one of the following a1 to a3:

[0098] a1. The UE receives a location measurement request message;

[0099] a2. The active BWP of the UE matches each PFL in all the PFLs corresponding to the UE;

[0100] a3. In each PFL of all PFLs corresponding to the UE, the reception time difference between the non-serving cell PRS and the serving cell PRS meets the first preset condition.

[0101] Optionally, in this embodiment, the location measurement request message is a request from a second network-side device, such as a location server, to the UE for location measurement / location estimation, carried via an LPP message. In the LPP protocol, the information element (IE) is the Request Location Information.

[0102] Optionally, in this embodiment of the application, when the first activation condition includes a2 as described above, if any PFL corresponding to the UE does not match the activated BWP of the UE, then the UE determines that all PRS processing windows corresponding to the UE are inactive.

[0103] Optionally, in the embodiments of this application, the matching of BWP and PFL includes at least one of the following features:

[0104] The subcarrier spacing (SCS) of BWP is the same as that of PFL;

[0105] BWP bandwidth covers PFL bandwidth;

[0106] The PRS of PFL within the BWP bandwidth meets the requirements.

[0107] Optionally, in this embodiment of the application, when the first activation condition includes the above a3, if the reception time difference between the non-serving cell PRS and the serving cell PRS in any PFL corresponding to the UE does not meet the first preset condition, then the UE determines that all PRS processing windows corresponding to the UE are inactive.

[0108] In this embodiment of the application, 'UE corresponding' can also be expressed as 'pre-configured for UE' or 'configured for UE'.

[0109] Optionally, in this embodiment of the application, the first preset condition includes one of the following: the reception time difference between the non-serving cell PRS and the serving cell PRS meets a threshold; in each PFL of all PFLs corresponding to the UE, the number of cells (here, a cell represents the cell that sends the PRS or the TRP (transmit and receive point)) whose reception time difference between the non-serving cell PRS and the serving cell PRS meets the threshold is greater than or equal to the first preset number.

[0110] Optionally, in the embodiments of this application, the first preset condition or the parameters in the first preset condition (e.g., the first preset quantity) can be determined by at least one method, such as protocol agreement, network indication, and UE selection.

[0111] It should be noted that when the activation information includes the first activation condition, the UE can simultaneously determine whether all PRS processing windows corresponding to the UE are activated or deactivated, without having to determine whether each PRS processing window corresponding to the UE is activated sequentially. Therefore, the speed at which the UE determines the activation behavior of its corresponding PRS processing window can be improved.

[0112] Optionally, the second activation condition in the embodiments of this application includes at least one of the following b1 to b4:

[0113] b1. The UE receives a location measurement request message;

[0114] b2. The UE receives the MG activation instruction information;

[0115] b3. The active BWP of the UE matches the PFL corresponding to at least one PRS processing window of the UE.

[0116] b4. In the PFL corresponding to at least one PRS processing window of the UE, the reception time difference between the non-serving cell PRS and the serving cell PRS meets the second preset condition.

[0117] Optionally, in this embodiment of the application, the MG activation indication information is sent by a first network-side device, such as the serving gNB, to indicate that the MG is in an active state or has been activated.

[0118] In this embodiment of the application, the MG activated by the MG activation indication information can be used for positioning measurement, such as PRS measurement.

[0119] Optionally, in this embodiment of the application, when the second activation condition includes the above-mentioned b3, if the activated BWP of the UE does not match a certain PFL corresponding to the UE, then the UE determines that the PRS processing window corresponding to the PFL is inactive.

[0120] Optionally, in this embodiment of the application, when the second activation condition includes the above-mentioned b3, for each PRS processing window corresponding to the UE, if the reception time difference between the non-serving cell PRS and the serving cell PRS in the PFL corresponding to a PRS processing window does not meet the second preset condition, then the UE can determine that the PRS processing window is not activated.

[0121] For a detailed description of the second preset condition, please refer to the relevant description of the first preset condition in the above embodiments. To avoid repetition, it will not be repeated here.

[0122] Optionally, the third activation condition in the embodiments of this application includes at least one of the following c1 to c6:

[0123] c1. The UE receives a positioning measurement request message;

[0124] c2. The UE receives the MG activation instruction information;

[0125] c3. The active BWP of the UE matches the PFL corresponding to at least one PRS processing window of the UE.

[0126] c4. At least one PRS processing window corresponding to the UE does not overlap with the temporal domain resources of the MG corresponding to the UE;

[0127] c5. The temporal domain resources that overlap between at least one PRS and the MG corresponding to the UE do not exceed a threshold;

[0128] c6. Whether at least one PRS processing window corresponding to the UE is activated or not is not affected by the activation of the MG corresponding to the UE.

[0129] Optionally, in this embodiment, when the third activation condition includes c4, if a certain PRS processing window corresponding to the UE overlaps with the temporal domain resources of one or more MGs corresponding to the UE, or if its activation is affected by the activation of one or more MGs corresponding to the UE, then the UE can determine that the PRS processing window is inactive. Further, the one or more MGs can be active MGs.

[0130] Optionally, the threshold in c6 above can be one of the following: a fixed threshold (e.g., in ms, slots, or symbols), a certain percentage of the PRS processing window duration (e.g., 50% of the PRS processing window duration), or a certain percentage of the MG duration (e.g., 50% of the MG duration).

[0131] It should be noted that when the activation information includes at least one of the second and third activation conditions, the UE needs to determine whether each PRS processing window corresponding to the UE is activated based on the activation information. This can improve accuracy.

[0132] Optionally, in the embodiments of this application, the above step 202a can be implemented by the following steps 202a1 or 202a2.

[0133] Step 202a1: If the UE meets the first activation condition, the UE determines that all PRS processing windows corresponding to the UE are activated.

[0134] Optionally, in this embodiment, when the activation information is a first activation condition, if the UE does not meet the first activation condition, the UE determines that all PRS processing windows corresponding to the UE are inactive, or the UE determines that all PFLs corresponding to the UE are inactive. This allows for rapid determination of the inactivity of all PRS processing windows corresponding to the UE.

[0135] Step 202a2: If the UE meets the second activation condition or the third activation condition, the UE determines that at least one PRS processing window corresponding to the UE is activated.

[0136] It is understood that in the embodiments of this application, in step 202a1 above, the target PRS processing window is all PRS processing windows corresponding to the UE; in step 202a2 above, the target PRS processing window is at least one PRS processing window corresponding to the UE, and the at least one PRS processing window is determined according to the second activation condition or the third activation condition.

[0137] In this embodiment, since the UE can determine that all PRS processing windows corresponding to the UE are activated when the UE meets the first activation condition, or can determine that at least one PRS processing window corresponding to the UE is activated when the UE meets at least one of the second activation condition and the third activation condition, the flexibility of the UE in determining the activation of its corresponding PRS processing window can be improved.

[0138] Optionally, in the embodiments of this application, step 202a2 can be implemented by step 202a21 and / or step 202a22 as described below.

[0139] Step 202a21: If the UE satisfies the second activation condition or the third activation condition, the UE determines that the non-overlapping temporal resources of the MG corresponding to the UE in each PRS processing window of at least one PRS processing window corresponding to the UE are activated.

[0140] Step 202a22: If the UE meets the second activation condition or the third activation condition, the UE determines that the portion of the temporal domain resources of the MG corresponding to the UE that overlaps with the UE's time domain resources in each PRS processing window of at least one PRS processing window corresponding to the UE is inactive.

[0141] Optionally, in this embodiment of the application, the UE may first obtain the time domain configuration information of the MG corresponding to the UE, and then determine whether the above-mentioned at least one PRS processing window overlaps with the time domain resources of the MG corresponding to the UE based on the time domain configuration information.

[0142] Optionally, in this embodiment of the application, the aforementioned time-domain configuration information can be obtained from at least one of the following: MG activation message, MG pre-configuration information, MG configuration information, and MG automatic activation indication information.

[0143] It should be noted that when the MG type of the UE is each frequency range (per FR) class, if the time domain resources of a PRS processing window corresponding to the UE overlap with those of an MG corresponding to the UE, then the PFL corresponding to the PRS processing window is associated with the same frequency range as the MG.

[0144] Optionally, if the MG type corresponding to the UE is a frequency range class, and the frequency range corresponding to the MG is different from the frequency range of the PFL corresponding to the PRS processing window, then whether the PRS processing window is activated or not is related to whether the MG is activated or not. Of course, it is not necessary to determine the time domain relationship between the PRS processing window and the MG.

[0145] In this embodiment, when the UE meets the second activation condition or the third activation condition, the non-overlapping temporal resources of the MG corresponding to the UE in each PRS processing window that meets the activation condition are further determined to be activated, thus further improving the accuracy of determining the activation of the PRS processing window.

[0146] Optionally, in the embodiments of this application, the above step 202a can be specifically implemented by the following step 202a1.

[0147] Step 202a1: If the UE meets the activation conditions, the UE assumes that the target PRS processing window will be activated and take effect after the first moment.

[0148] The first moment includes one of the following:

[0149] The moment when the UE receives the location measurement request message;

[0150] The moment when the UE receives the MG activation instruction information;

[0151] The time after the UE receives the positioning measurement request message, which is the first preset duration.

[0152] The second preset duration after the UE receives the MG activation indication information;

[0153] The moment when the UE sends the confirmation message for the location measurement request message;

[0154] The moment when the UE sends a confirmation message for the MG activation instruction information;

[0155] The third preset time interval after the UE sends the confirmation message for the location measurement request message;

[0156] The fourth preset time after the UE sends the confirmation message for the MG activation instruction information.

[0157] In this embodiment of the application, the first preset duration, the second preset duration, the third preset duration, and the fourth preset duration may be the same or different.

[0158] Optionally, in the embodiments of this application, the first preset duration, the second preset duration, the third preset duration, and the fourth preset duration can be agreed upon by a protocol or indicated by a network.

[0159] It should be noted that each moment in the embodiments of this application can be a slot, a symbol, a subframe, a time window, or a time-domain location, etc.

[0160] Optionally, the unit of preset duration includes, but is not limited to, slot, symbol, subframe, time window, or time domain position.

[0161] Optionally, when each moment is a time slot, the preset duration in this embodiment is one or more time slots; when each moment is a subframe, the preset duration is one or more subframes; when each moment is a time domain location, the preset duration is one or more time domain locations; when each moment is a symbol, the preset duration is one or more symbols.

[0162] Optionally, in this embodiment of the application, if the UE receives MG activation indication information, the first moment is the relevant moment of the MG activation indication information. The relevant moment is: the moment when the UE receives the MG activation indication information, the moment after the UE receives the MG activation indication information for a second preset duration, the moment when the UE sends the confirmation message of the MG activation indication information, or the moment after the UE sends the confirmation message of the MG activation indication information for a fourth preset duration.

[0163] Optionally, in this embodiment of the application, when the UE's location configuration (information) meets the first preset configuration (information), the activation information includes activation conditions. In other words, when the UE's location configuration meets the first preset configuration, the UE can determine whether the target object is activated based on the activation conditions.

[0164] The first preset configuration may include at least one of the following:

[0165] The number of PRS processing windows configured is 1;

[0166] The pre-configured number of PRS processing windows is 1;

[0167] The number of PFLs is 1;

[0168] The pre-configured number of MGs is 1;

[0169] The number of MGs configured is 1;

[0170] The pre-configured MG type has a quantity of 1 MG for each frequency range class;

[0171] The configured MG type has a quantity of 1 MG for each frequency range class;

[0172] Each frequency range contains 1 PFL.

[0173] It should be noted that in this embodiment of the application, the UE's location configuration is configured / indicated by the network.

[0174] Optionally, in this embodiment, for a certain activation condition (a first activation condition, a second activation condition, or a third activation condition), if all sub-conditions of the activation condition are satisfied (for example, if an activation condition includes sub-condition 1 and sub-condition 2, the activation condition is satisfied only if both sub-condition 1 and sub-condition 2 are satisfied), the UE activates the corresponding PRS processing window, or the terminal assumes that the corresponding PRS processing window is already activated. In other words, if one of the sub-conditions of an activation condition is not satisfied, the UE assumes that the corresponding PRS processing window is inactive and does not expect to use the measurement of PRS within the corresponding PRS Processing window.

[0175] In this embodiment of the application, when the UE needs to perform PRS measurement, since the UE can directly determine the activation of some or all PRS processing windows corresponding to the UE based on the activation condition judgment, without needing to determine the activation of the PRS processing window corresponding to the UE based on the PRS processing window activation indication information sent by the network side device (e.g., the first network side device), it can quickly determine which PRS processing windows corresponding to the UE are activated, and can further save signaling overhead.

[0176] The second implementation method is as follows: the activation information obtained by the UE includes at least one of the following: PRS processing window indication information; MG indication information; no MG activation indication information.

[0177] Among them, the PRS processing window indication information is used to indicate the activation behavior of the target PRS processing window; the MG indication information is used to indicate the activation behavior of the target MG; and the no-MG activation indication information is used to indicate no MG activation.

[0178] Optionally, in the embodiments of this application, the activation behavior includes: activation or deactivation.

[0179] Optionally, in this embodiment of the application, when the activation information obtained by the UE is sent by the first network-side device, the activation information may include at least one of the following: PRS processing window indication information; MG indication information; no MG activation indication information.

[0180] Optionally, in this embodiment of the application, the above-mentioned PRS processing window indication information includes at least one of the following: the identifier of the target PRS processing window; the configuration identifier of the target PRS processing window; the activation identifier of the PRS processing window; the deactivation identifier of the PRS processing window; and the PFL identifier corresponding to the target PRS processing window.

[0181] The PRS processing window activation indicator indicates that the PRS processing window indication information is used to activate the target PRS processing window; the PRS processing window deactivation indicator indicates that the PRS processing window indication information is used to deactivate the target PRS processing window.

[0182] Optionally, in this embodiment of the application, when the target PRS processing window is multiple PRS processing windows corresponding to the UE, the PRS processing window indication information includes the identifier or configuration identifier of these PRS processing windows, indicating that the PRS processing window indication information is used to indicate the activation behavior of these PRS processing windows.

[0183] Optionally, in this embodiment of the application, the number of PFL identifiers in the PRS processing window indication information is the same as the number of PFLs corresponding to the target PRS processing window, and they correspond one-to-one.

[0184] It is understood that in the embodiments of this application, when the PRS processing window indication information includes PFL identifiers, it means that the PRS processing window indication information is used to indicate the activation behavior of the PRS processing window corresponding to / associated with these PFL identifiers.

[0185] Optionally, in this embodiment of the application, when the PRS processing window indication information is PRS processing window activation indication information or PRS processing window deactivation indication information, the PRS processing window indication information includes at least a PRS processing window activation identifier or a PRS processing window deactivation identifier.

[0186] For example, when the PRS processing window indication information is the PRS processing window activation indication information, the PRS processing window indication information may include: the identifier of the target PRS processing window; the configuration identifier of the target PRS processing window; the PRS processing window activation identifier; and the PFL identifier corresponding to the target PRS processing window.

[0187] For example, when the PRS processing window indication information is the PRS processing window deactivation indication information, the PRS processing window indication information may include: the identifier of the target PRS processing window; the configuration identifier of the target PRS processing window; the PRS processing window deactivation identifier; and the PFL identifier corresponding to the target PRS processing window.

[0188] Optionally, in this embodiment, the PRS processing window indication information can be indicated by a bitmap. The length of the bitmap is equal to the number of target PRS processing windows, each bit in the bitmap corresponds to one target PRS processing window, and the value of each bit is used to indicate the activation behavior of that target PRS processing window. Optionally, in addition to the indicating bitmap, an indication can be added stating that the bitmap is used to activate or deactivate the target PRS processing window.

[0189] Optionally, in this embodiment of the application, the correspondence between the bits of the bitmap and the target PRS processing window can be determined by one of the protocol agreement and network indication.

[0190] For example, the 0th bit of the bitmap corresponds to the target PRS processing window marked as 0, and the xth bit of the bitmap corresponds to the target PRS processing window marked as x.

[0191] Optionally, in this embodiment of the application, a bit value of 1 in the bit diagram represents 'activation'; a bit value of 0 in the bit diagram represents 'deactivation' or 'deactivation'. It can be understood that the meanings of 0 and 1 can be interchanged.

[0192] Optionally, in this embodiment, a bitmap can be used to indicate the activation of some PRS processing windows and the deactivation of others. Therefore, the PRS processing window indication information using a bitmap can be collectively referred to as 'activation and deactivation indications', without the need to define separate activation and deactivation indications. In this case, the PRS processing window indication information can be both activation and deactivation indication information for PRS processing windows.

[0193] It is understood that in the embodiments of this application, the MG indication information can also be indicated by a bitmap. For specific indication methods, please refer to the relevant description of the indication of PRS processing window indication information by bitmap.

[0194] Optionally, the activation and / or deactivation indicators for the PRS processing window can be included in the same MAC CE as the MG activation and / or deactivation indicators.

[0195] Optionally, in the second implementation of this application embodiment, the activation information can be indicated by at least one of Radio Resource Control (RRC), Medium Access Control (MACCE), and Downlink Control Information (DCI).

[0196] Optionally, in this embodiment of the application, all the information in the activation information is contained in the same MAC CE.

[0197] To facilitate understanding of the PRS measurement method provided in the embodiments of this application, a MAC CE design for activating the MG and / or processing window is given below, which includes at least one of the following IEs:

[0198] IE0: Indicates whether the MAC CE is used for MG activation (deactivation); or PRS processing window activation (deactivation), or both MG activation (deactivation) and PRS processing window activation (deactivation).

[0199] Optionally, the bit length in the MAC CE is 1 to 2 bits.

[0200] IE1: Indicates whether the MAC CE should be used for activation or to activate MG;

[0201] Optionally, the bit length of IE1 is 1 bit.

[0202] IE2: MG configuration identifier or MG identifier, indicating the MG configuration identifier or MG identifier that needs to be activated or deactivated.

[0203] Optionally, the IE2 can also be expanded to multiple MGs for activating or deactivating multiple MGs.

[0204] Optionally, for each UE class of MG type, or for each frequency domain range of MG type, the configuration identifier or identifier of the network (pre)configured MG is not counted according to each frequency domain range but is counted as a whole.

[0205] IE3: Configuration identifier or identifier of the MG in the first target frequency domain range. If the MG type is a frequency domain range class, IE3 indicates that a specific MG in a certain frequency domain range (such as FR1) is activated.

[0206] Optionally, the IE3 can also be expanded to multiple MGs to activate or deactivate multiple MGs within the FR1.

[0207] IE4: Configuration identifier or identifier of the MG in the second target frequency domain range. If the MG type is a frequency domain range class, this IE4 indicates that a specific MG in a certain frequency domain range (such as FR2) is activated.

[0208] Optionally, the IE4 can also be expanded to multiple MGs to activate or deactivate multiple MGs within the frequency domain range.

[0209] IE5: MG configuration identifier or MG identifier for the xth target frequency domain range (e.g., FRx).

[0210] Optionally, the IE can also be expanded to multiple MGs for activating or deactivating the FR.

[0211] IE6: Indicates whether the MAC CE is used to activate or deactivate the PRS processing window;

[0212] Optional, the bit length is 1 bit

[0213] IE7: PRS processing window configuration identifier or identifier, indicating the PRS processing window configuration ID or ID that needs to be activated or deactivated;

[0214] Optionally, the IE can also be expanded into multiple PRS processing windows for activation or deactivation.

[0215] IE8: PRS processing window 'activate and deactivate bitmap'. This IE uses a bitmap to simultaneously activate and / or deactivate at least one PRS processing window.

[0216] Optionally, the IE length is equal to the bitmap length, which is equal to the (pre)configured number of PRS processing windows.

[0217] Optionally, in this embodiment of the application, when the activation information obtained by the UE includes PRS processing window indication information, and the PRS processing window indicates the activation state of the target PRS processing window, the activation or deactivation time of the target PRS processing window is one of the following: the time when the UE sends the confirmation message of the PRS processing window indication information; or the time after the UE sends the confirmation message of the PRS processing window indication information for a fifth preset period of time.

[0218] For example, the activation or deactivation time of the target PRS processing window is: the time when the UE sends the confirmation message of the PRS processing window indication information + Nms (i.e., the fifth preset duration), such as N=3.

[0219] In this embodiment of the application, the fifth preset duration can be agreed upon by the protocol or indicated by the network.

[0220] For example, when the PRS processing window indication information is indicated by the MAC CE, the MAC CE can carry a fifth preset duration, specifically 3 time slots * 2 to the power of u, where u is related to the subcarrier spacing SCS corresponding to the time slot (specifically SCS = 15kHz, u = 0; SCS = 30kHz, u = 1; SCS = 60kHz, u = 2; SCS = 120kHz, u = 3; SCS = 240kHz, u = 4; SCS = 480kHz, u = 5...).

[0221] Optionally, in this embodiment of the application, the activation information obtained by the UE includes PRS processing window indication information, and the above step 202 can be implemented by the following steps 202b or 202c.

[0222] Step 202b: If the PRS processing window indication information indicates that the target PRS processing window is activated, the UE determines that the target PRS processing window is activated.

[0223] Step 202c: If the PRS processing window indication information indicates that the target PRS processing window is deactivated, the UE determines that the target PRS processing window is inactive.

[0224] Optionally, in this embodiment, the activation information obtained by the UE includes: MG indication information, and the target object may include a target MG and a target PRS processing window, wherein the target PRS processing window is at least one PRS processing window corresponding to the UE. Step 202 described above can be specifically implemented through step 202d below.

[0225] Step 202d: If the MG indication information indicates that the target MG is active, the UE determines whether at least one PRS processing window is active based on the target association relationship.

[0226] The aforementioned target association may include at least one of the following:

[0227] The first association relationship between the target MG and at least one PRS processing window corresponding to the UE;

[0228] A second association relationship between the target MG and at least one PFL corresponding to the UE;

[0229] The third association between each PFL in at least one PFL and one or more PRS processing windows corresponding to the UE.

[0230] The methods for determining the first, second, and third association relationships are explained below.

[0231] Optionally, in this embodiment of the application, the first association relationship can be determined in one of the following ways:

[0232] The association between the identifier of the target MG and the identifier of the at least one PRS processing window, such as {identifier of the target MG, identifier of the at least one PRS processing window};

[0236] The configuration information of each PRS processing window in at least one PRS processing window indicates the identifier of the target MG;

[0237] In each of the at least one PRS processing windows, a configuration identifier for the target MG is indicated.

[0238] Optionally, in the embodiments of this application, the first association relationship between the target MG and at least one PRS processing window corresponding to the UE can be configured, pre-configured or indicated by the network; or it can be agreed by the protocol.

[0245] Optionally, in this embodiment, the first information may include the configuration information of the target MG and the configuration information of the at least one PFL. In this embodiment, if the configuration information of the target MG and the configuration information of the at least one PFL satisfy the first condition, the target MG and the at least one PFL have the second association relationship.

[0246] The first condition includes at least one of the following:

[0247] The target MG's MG type is per UE class;

[0265] The TRP of the PRS transmission is related to the expected RSTD and / or the expected RSTD uncertainty of the reference cell;

[0266] The expected RSTD and / or expected RSTD uncertainty of the reference cell TRP and serving cell TRP;

[0268] Optionally, in this embodiment of the application, the third association relationship is determined by the second information, which may include at least one of the following:

[0269] Information about pre-configured third-party relationships;

[0270] Information about the configured third association;

[0271] At least one PFL configuration information and target configuration information, wherein the target configuration information is the configuration information of one or more PRS processing windows corresponding to the UE.

[0272] Optionally, in this embodiment of the application, if the second information may include configuration information and target configuration information of at least one PFL, then if the configuration information and target configuration information of each PFL of the at least one PFL satisfy the second condition, each PFL has a third association relationship with one or more PRS processing windows corresponding to the UE.

[0275] The frequency band associated with each PFL is the same as the frequency band associated with one or more PRS processing windows corresponding to the UE;

[0276] The component carrier CC associated with each PFL is the same as the CC associated with one or more PRS processing windows corresponding to the UE.

[0277] The frequency range associated with each PFL is the same as the frequency range associated with one or more PRS processing windows corresponding to the UE;

[0278] The subcarrier spacing SCS associated with each PFL is the same as the SCS associated with one or more PRS processing windows corresponding to the UE.

[0279] The temporal resources of one or more PRS processing windows corresponding to the UE include the PRS temporal location of each PFL;

[0280] The temporal resources of one or more PRS processing windows corresponding to the UE partially overlap with the temporal location of the PRS of each PFL.

[0281] The overlap between the time-domain resources of one or more PRS processing windows corresponding to the UE and the PRS time-domain location of each PFL exceeds a certain threshold, which is one of the following: a fixed threshold (e.g., in ms, slots, or symbols), a certain proportion of the PRS processing window duration (e.g., 50% of the PRS processing window duration), or a certain proportion of the PRS time-domain range (e.g., 50% of the PRS time-domain range in a PRS measurement instance).

[0282] The bandwidth associated with each PFL is the same as the bandwidth associated with one or more PRS processing windows corresponding to the UE.

[0283] Optionally, generally, the correspondence between the PRS processing window and the PFL within the scope of this application can be obtained from a third association relationship.

[0284] Optionally, in this embodiment of the application, the target association relationship includes a first association relationship, and the above step 202d can be implemented by the following step 202d1.

[0285] Step 202d1: When the MG indication information indicates that the target MG is active, the UE assumes, based on the first association relationship, that: at least one PRS processing window is inactive; or, the activation or deactivation of at least one PRS processing window is not affected by the activation of the target MG; or, at least one PRS processing window is active.

[0286] In step 202d1 above, (1), if the UE assumes that at least one PRS processing window is inactive, then:

[0287] a. Optionally, the activation of at least one PRS processing window associated with the target MG is affected by the activation of the target MG. In other words, when the target MG is activated, the activation of at least one PRS processing window associated with the target MG will be affected.

[0288] b. Optionally, when the target MG is not activated, the activation of at least one PRS processing window associated with the target MG is not affected;

[0289] c. Optionally, when the target MG is activated, the activation of other PRS processing windows in the PRS processing window corresponding to the UE, except for at least one PRS processing window associated with the target MG, will be affected.

[0290] d. Optionally, if the MG type of the target MG is for each frequency range class (per FR), then the target MG is associated with the same frequency range as at least one associated PRS processing window.

[0291] e. Optionally, if there are multiple target MGs, when these MGs are activated, the UE takes the union of the PRS processing windows associated with these MGs, and the corresponding PRS processing window (i.e., at least one of the above PRS processing windows, i.e., the target PRS processing window) cannot be activated. Whether the remaining PRS processing windows of the UE are activated or not is not affected.

[0292] (2) If the UE assumes that at least one PRS processing window is active, or that the activation or deactivation of at least one PRS processing window is not affected by the activation of the target MG, then:

[0293] a. Optionally, if the MG type of the target MG is for each frequency range class, the target MG is associated with the same frequency range as at least one associated PRS processing window.

[0294] b. Optionally, if there are multiple target MGs, then when these multiple target MGs are activated, the activation or deactivation of the PRS processing windows associated with each target MG (i.e., at least some of the aforementioned PRS processing windows) within the corresponding PRS processing windows of these multiple target MGs is unaffected. In other words, the activation or deactivation of these at least some PRS processing windows is not affected by any target MG.

[0295] Optionally, if the MG type of the target MG is each frequency range class, and if the frequency range of the target MG is different from the PRS processing window, the activation or deactivation of the PRS processing window is not affected by the MG.

[0296] Optionally, in this embodiment of the application, the target association relationship includes at least one of the second association relationship and the third association relationship, and the above step 202d can be specifically implemented by the following step 202d2.

[0297] Step 202d2: When the MG indication information indicates that the target MG is activated, the UE determines that at least one PRS processing window is activated based on at least one of the second association and the third association.

[0298] Specifically, the at least one PRS processing window refers to the PRS processing window associated with other PFLs besides the one associated with the active MG. It can be understood that the active MG includes the target MG and / or MGs that were already activated / determined to be activated before receiving the MG indication information.

[0299] Optionally, in this embodiment, the activation information includes MG indication information or no MG activation indication information, and the target object includes the target PRS processing window. Step 202 can be specifically implemented through step 202e below.

[0300] Step 202e: If the UE does not receive MG indication information, or the MG indication information indicates that all MGs are inactive, or if it receives no MG activation indication information, the UE determines that all PRS processing windows corresponding to the UE are activated. Here, "all" refers to "all" or "all" corresponding to the UE.

[0301] Optionally, in this embodiment, the activation information obtained by the UE includes MG indication information or no MG activation indication information, the MG indication information indicates that the target MG is activated, and the target object includes the target PRS processing window. Step 202 above can be specifically implemented by at least one of the following steps 202f and 202g:

[0302] Step 202f: If the UE does not receive MG indication information, or the MG indication information indicates that the MG is not active, or if no MG activation indication information is received, the UE determines that at least one PRS processing window corresponding to the UE is active.

[0303] Step 202g: When the MG indication information indicates that the MG is active: 1) The UE determines that at least one PRS processing window corresponding to the UE is inactive; or, 2) The UE determines that the portion of at least one PRS processing window corresponding to the UE that overlaps with the MG is inactive; or, 3) The UE determines that at least one PRS processing window corresponding to the UE that overlaps with the MG is inactive; or, 4) The UE determines that at least one PRS processing window corresponding to the UE that overlaps with the MG by more than a threshold (referred to as threshold 2) is inactive.

[0304] Optionally, in the embodiments of this application, the threshold 2 can be one of the following: a fixed threshold (e.g., in ms, slots, or symbols), a certain proportion of the PRS processing window duration (e.g., 50% of the PRS processing window duration), or a certain proportion of the MG duration (e.g., 50% of the MG duration).

[0305] Optionally, in this embodiment of the application, when the MG indication information indicates that the MG is activated, the UE may also determine that in the UE's corresponding PRS processing window, the PRS processing window other than the activated PRS processing window is activated, or determine that the part of the PRS processing window other than the non-activated part is activated.

[0306] It should be noted that in this embodiment of the application, the UE does not receive MG indication information, which may be because the UE does not receive MG indication information within a time window.

[0307] Optionally, in this embodiment of the application, the starting point of the time window can be one of the following: the time when the UE receives the location information request message, the time when the UE receives the (pre)configuration information of the MG, the time when the UE sends the confirmation message of the location information request message, the time when the UE sends the confirmation message of the (pre)configuration information of the MG, the time when the UE sends the confirmation message of the location information request message + N (N is agreed by the protocol or indicated by the network), and the time when the UE sends the confirmation message of the (pre)configuration information of the MG + N.

[0308] Optionally, in this embodiment of the application, the length of the time window can be agreed upon by the protocol or indicated by the network, such as being included in the (pre)configuration information of the PRS processing window or the (pre)configuration information of the MG.

[0309] Optionally, in this embodiment, in steps 202f and 202g above, if the MG type of the MG corresponding to the UE is each UE class, then the at least one PRS processing window is all the PRS processing windows corresponding to the UE. If the MG type of the MG corresponding to the UE is each frequency domain range class, then the at least one PRS processing window is the PRS processing window among all the PRS processing windows corresponding to the UE whose frequency domain range is the same as the frequency domain range associated with the MG indication information indicating MG activation, or the MG indication information indicating MG inactivation or no MG activation.

[0310] Optionally, in the embodiments of this application, step 202 above can be specifically implemented by step 202h below.

[0311] Step 202h: If the UE determines that the target object is activated, and the UE receives the MG activation indication information, then the UE determines that the target object will start to be activated and take effect after the second time.

[0312] The second moment includes one of the following:

[0313] The moment when the UE receives the MG activation instruction information;

[0314] The time after the UE receives the MG activation instruction information, which is the sixth preset time interval;

[0315] The moment when the UE sends a confirmation message for the MG activation instruction information;

[0316] The time seven preset durations after the UE sends the confirmation message for the MG activation instruction information.

[0317] In this embodiment of the application, both the sixth preset duration and the sixth preset duration can be agreed upon by the protocol or indicated by the network.

[0318] In the PRS measurement method provided in this application embodiment, the UE can determine whether a target object is active based on activation information. When the target object is active, it is used for PRS measurement. The target object includes at least one of the following: a target PRS processing window and a target measurement interval (MG). Through this scheme, when the UE requires PRS measurement, it can directly determine whether the target object is active based on activation information. That is, the UE can quickly determine whether the target object is active, thus enabling the UE to perform PRS measurement using the target object when it is determined to be active. This allows for rapid measurement of PRS, such as PRS with bandwidth exceeding the UE's active BWP range.

[0319] Optionally, in this embodiment of the application, after step 202 above, the PRS measurement method provided in this embodiment of the application may further include step 203 below.

[0320] Step 203: When the UE determines that both the target MG and the target PRS processing window are active, the UE does not expect the target MG and the target PRS processing window to overlap in the temporal domain.

[0321] Optionally, in this embodiment of the application, after step 202 above, the PRS measurement method provided in this embodiment of the application may further include step 204 below.

[0322] Step 204: If the UE determines that the target PRS processing window is active, and if the temporal domain resources of the target PRS processing window at least partially overlap with those of the active MG, then the UE performs at least one of the following:

[0323] Perform PRS measurements in the portion of the target PRS processing window that does not overlap with the temporal resources of the activated MG;

[0324] PRS measurements are performed using the target PRS processing window for portions of the target PRS processing window that do not overlap with the temporal resources of the active MG.

[0325] The goal is to perform PRS measurements using the active MG in the overlapping time domain between the target PRS processing window and the active MG.

[0326] PRS measurements are not expected to be performed in the overlapping time domain between the target PRS processing window and the activated MG;

[0327] It is determined that the PRS measurements of the UE outside the overlapping time domain between the target PRS processing window and the active MG are not affected;

[0328] Identify the inactive portion of the temporal resources in the target PRS processing window that overlaps with those of the active MG;

[0329] Identify the non-overlapping temporal resources of the target PRS processing window with the activated MG.

[0330] Optionally, in this embodiment of the application, when the target PRS processing window and the time domain resources of the activated MG at least partially overlap, if the MG type of the MG corresponding to the UE is each frequency domain range class, then the frequency domain range associated with the target PRS processing window and the MG is the same.

[0331] Optionally, in this embodiment of the application, before step 201 above, the PRS measurement method provided in this embodiment of the application may further include step 205 below.

[0332] Step 205: The UE receives the target information.

[0333] It is understood that in this embodiment, the target information can be sent by either a first network-side device or a second network-side device. For example, the first network-side device can send the target information to the second network-side device, and then the second network-side device can send the target information to the UE.

[0334] In this embodiment of the application, the target information may include at least one set of (pre)configuration information for PRS processing windows.

[0335] The configuration information of a set of PRS processing windows includes at least one of the following:

[0336] The PRS processing window label;

[0337] Configuration identifiers for the PRS processing window;

[0338] The initial activation state of the PRS processing window, i.e., 'activated' or 'inactive';

[0339] The activation methods for the PRS processing window include explicit activation and implicit activation;

[0340] The configuration information of the PRS processing window is associated with at least one PFL identifier, indicating that each group of PRS processing windows is associated with at least one PFL.

[0341] The association between the PRS processing window and the MG corresponding to the UE;

[0342] The validity period of the configuration information in the PRS processing window;

[0343] The valid area for configuration information in the PRS processing window;

[0344] PRS processing window associated frequency points;

[0345] The type of PRS processing window, such as per UE class, per bandwidth class, or per CC class;

[0346] The standard configuration of the PRS processing window includes, but is not limited to, at least one of the following: length, period, start time, associated serving cell identifier, associated SCS, and priority.

[0347] Optionally, in this embodiment, explicit activation refers to activating / deactivating the PRS processing window through PRS processing window indication information and informing the UE of the activation / deactivation of the PRS processing window by sending PRS indication information to the UE. Implicit activation refers to two main methods: determining whether the PRS processing window is activated based on activation conditions or based on MG indication information. Accordingly, in implicit activation, the first network-side device can activate or deactivate the PRS processing window based on activation conditions or MG indication information; furthermore, after activating / deactivating the PRS processing window, there is no need to send PRS indication information to the UE again, and the UE can determine whether the PRS processing window is activated based on the activation information obtained by the UE.

[0348] Optionally, in this embodiment of the application, the validity period of the configuration information is as follows: for example, the validity period of the configuration information or (or the valid timer) is T1. After the UE receives the configuration information, the configuration information is valid for a period of T1, and the configuration information is no longer valid after the period of T1.

[0349] For example, a set of PRS processing windows has pre-configured information, pre-configuring the initial state of the set of PRS processing windows as inactive, and the validity period of the pre-configuration information of the set of PRS processing windows is T1. If the set of PRS processing windows fails to activate within the time limit of T1, then after the time limit of T1, the UE assumes that the pre-configuration information of the set of PRS processing windows has become invalid.

[0350] Optionally, in this embodiment, the aforementioned T1 duration can also be applied to the change of the activation state of the group of PRS processing windows from active to inactive. For example, when the pre-configured activation state of the group of PRS processing windows changes from active to inactive, the timing starts. If the group of PRS processing windows is still not activated within T1 duration, then after T1 duration, the UE assumes that the (pre)configuration information of the group of PRS processing windows has become invalid.

[0351] Optionally, in this embodiment of the application, after the UE receives the (pre)configuration information of the group of PRS processing windows for a period of time T1, the (pre)configuration information of the group of PRS processing windows becomes invalid regardless of whether the group of PRS processing windows is activated or not.

[0352] Optionally, in this embodiment, the validity period of the (pre)configuration information of the PRS processing window can also be agreed upon by the protocol or indicated by the UE or location server. After the (pre)configuration information of the PRS processing window expires, the UE can report the configuration failure information to the serving gNB or location server, such as reporting the configuration identifier of the failed PRS processing window, the reason for failure, etc.

[0353] Optionally, in this embodiment, the valid area of ​​the configuration information refers to the valid area of ​​the pre-configured measurement interval configuration indicated by the configuration information. Beyond this valid area, the pre-configured measurement interval configuration becomes invalid. This valid area includes, but is not limited to, at least one of the following:

[0354] The cell list can be represented by cell IDs such as Physical Cell Identification (PCI) and NR Cell Global Identifier (NCGI);

[0355] A specific area, such as a certain area within a residential community;

[0356] If the change in the measurement of a specific reference signal does not exceed a certain threshold, such as the change in the Reference Signal Receiving Power (RSRP) of the Synchronization Signal and PBCH Block (SSB) not exceeding a certain threshold, the UE assumes that the configuration information is valid; otherwise, it is invalid.

[0357] The area of ​​the UE's current serving cell (or camped cell).

[0358] Optionally, in this embodiment of the application, the effective area of ​​the configuration information may also be agreed upon by the protocol or indicated by the UE or the location server.

[0359] Optionally, in the embodiments of this application, the target information is indicated by at least one of RRC, LPP, MAC CE, and DCI.

[0360] Optionally, in this embodiment of the application, if the target information includes (pre)configuration information of multiple sets of PRS processing windows, and each set of pre)configuration information contains the same parameters, then these parameters can be used as common parameters of the (pre)configuration information of multiple sets of PRS processing windows, and carried at the same or higher level as the (pre)configuration information of multiple sets of PRS processing windows.

[0361] Among them, the common parameters of the above multiple sets of (pre)configuration information include at least one of the following: initial activation status, activation method, effective time of PRS processing window configuration information, effective area of ​​PRS processing window configuration information, type of PRS processing window, etc.

[0362] Optionally, in this embodiment of the application, if the UE's positioning resource configuration meets the second configuration condition, the activation method is implicit activation or configuration activation method; otherwise, it is default explicit activation.

[0363] The second preset configuration includes at least one of the following:

[0364] The number of PRS processing windows configured is 1;

[0365] The pre-configured number of PRS processing windows is 1;

[0366] The number of PFLs configured is 1;

[0367] The number of pre-configured PFLs is 1;

[0368] The number of MGs configured is 1;

[0369] The pre-configured number of MGs is 1;

[0370] The configured MG type has a quantity of 1 MG for each frequency range class;

[0371] The pre-configured MG type has a quantity of 1 MG for each frequency range class;

[0372] The number of MGs in each frequency domain range is 1;

[0373] The number of PFLs for each frequency range is 1.

[0374] Optionally, in the embodiments of this application, combined with Figure 2 ,like Figure 3 As shown, prior to step 201 above, the PRS measurement method provided in this application embodiment may further include steps 206 and 207 as described below.

[0375] Step 206: The UE sends its capability to the target network-side device.

[0376] Step 207: The target network-side device receives the UE's transmission capability.

[0377] The target network-side device includes at least one of a first network-side device and a second network-side device, and the capabilities of the UE include at least one of the following: whether the UE supports implicit activation of MG; whether the UE supports implicit activation of PRS processing window; whether the UE supports activation of PRS processing window by pre-configured activation method; whether the UE supports activation of MG by pre-configured activation method; whether the UE supports pre-configured PRS processing window; whether the UE supports activation of processing window via MAC CE.

[0378] It should be noted that when the target device includes a second network-side device, the UE can send its capabilities to the second network-side device in two ways: the UE can directly send its capabilities to the second network-side device, or the UE can first send its capabilities to the first network-side device, and then the first network-side device can send its capabilities to the second network-side device.

[0379] Optionally, in this embodiment of the application, the second network-side device may be a location server.

[0380] Optionally, in this embodiment of the application, when the UE supports implicit MG activation, the UE can determine whether the MG is activated based on the activation conditions or PRS activation indication information; otherwise, the UE can determine whether the MG is activated based on the MG indication information.

[0381] When the UE supports implicit activation of the PRS processing window, the UE can determine whether the PRS processing window is activated based on the activation condition or MG activation indication information; otherwise, the UE can determine whether the PRS processing window is activated based on the PRS processing window indication information.

[0382] In this embodiment of the application, the pre-configured activation method may include: implicit activation or explicit activation (e.g., activation via MAC CE).

The activation request message is used to request the activation of the target object. The activation request message includes at least one of the following: MG activation request message and PRS processing window activation request message.

[0387] It is understood that, in this embodiment of the application, after the second network-side device receives the activation request message, it can send the activation request message to the first network-side device, and then the first network-side device can receive the activation request message and activate the target object.

[0388] Optionally, the MG activation request message in this application embodiment includes at least one of the following: MG activation request identifier; MG activation method; MG activation effective time; and indication information of the MG to be activated.

[0391] It should be noted that, in this embodiment of the application, the second network-side device is also used to send a positioning measurement request message to the UE, so that after receiving the positioning measurement request message, the UE can send an activation request message.

[0392] This application provides a PRS processing window measurement method, in which a first network-side device can perform a target operation, the target operation including at least one of the following: (1) activating or deactivating (i.e. deactivating) a target object according to activation information; (2) sending activation information to the UE, the activation information being used to determine whether the target object is activated.

[0470] Taking the activation request message, including the MG activation request message, as an example: the MG activation effective time refers to when the MG becomes effective. Information indicating the target MG includes an identifier or a bitmap; the identifier indicates the identifier of the PRS processing window and / or MG that needs to be activated, and may contain at least one identifier. The bitmap uses '0, 1' bits to indicate whether the PRS processing window and / or MG needs to be activated or not. The length of the bitmap is equal to the (pre)configured number of PRS processing windows or MGs.

[0471] Optionally, the effective time of the MG and / or PRS processing window (such as a (pre-configured) PRS processing window) includes at least one of the following: start effective time, end effective time, and effective duration. Optionally, the effective time can also be a periodic time window, and may further include at least one of the following: period, period offset, duration of each period, and number of periods (here, an effective time window may contain the period of at least one target object). This effective time (window) can be equivalent to the PRS measurement time (window).

[0472] Optionally, the indication of the effective time of the pre-configured measurement interval may also be included in the activation request message of the pre-configured object (e.g., the pre-configured MG and / or PRS processing window).

[0473] Optionally, the indication of the effective time of the pre-configured measurement interval can also be sent to the terminal, for example, by a first network-side device (e.g., through pre-configuration or activation information) or by a second network-side device (e.g., through an LPP message, such as carried in a location measurement request). The first network-side device can activate the pre-configured target device within the effective time, that is, the pre-configured target status is active within the effective time, and the pre-configured measurement interval status is inactive outside the effective time.

[0474] Optionally, the effective time can be an absolute time or a time relative to the first network-side device SFN0 (system frame 0).

[0475] Optionally, the absolute time is Coordinated Universal Time (UTC).

[0476] Optionally, the time relative to the SFN0 (system frame 0) of the first network-side device is the time relative to the SFN0 of a certain serving cell (Pcell, Pscell, or a certain scell) in the first network-side device.

[0477] Optionally, the SFN0 time of which serving cell is based can be agreed upon by protocol or indicated by other nodes (such as a second network-side device or UE).

[0478] Optionally, when the effective time is related to a slot or symbol, it is also necessary to indicate or agree on the SCS corresponding to the slot or symbol.

[0479] One implementation: Indicate that a certain slot or symbol, MG and / or PRS processing window is active in a certain serving cell.

[0480] One implementation: The instruction takes effect after a preset time following a specific subframe, system frame, slot, or symbol within a serving cell. The preset time unit can be one of ms, s, us, ns, slot, symbol, slot, Ts, or Tc. The timing of the instruction following a specific subframe, system frame, slot, or symbol can be determined by a protocol or by other nodes.

[0481] Optionally, the time unit can be at least one of ms, s, us, ns, slot, symbol, slot, timestamp Ts, and timecode Tc.

[0482] Optionally, the above effective time corresponds to the time corresponding to the first PRS occasion after the pre-configured object takes effect and / or the time corresponding to the last PRS occasion, that is, the pre-configured object starts to be used at the first PRS occasion and / or stops being used at the last PRS occasion.

[0483] Optionally, PRS timing can also be expressed as PRS sample, PRS period, or PRS instance.

[0484] Optionally, the activation request message may also include: the effective time requirement of the pre-configured object, that is, the first network-side device is required to activate the target object within a time T after receiving the activation request;

[0485] This application provides a PRS measurement method. Since the first network-side device can activate or deactivate a target object based on an activation condition, when another activation condition corresponding to the activation condition is configured / indicated to the UE, the UE can autonomously determine whether the target object is activated based on the activation condition it obtains, without the first network-side device needing to send indication information indicating the activation behavior of the target object to the UE after activating or deactivating the target object. This can save signaling overhead.

[0486] Optionally, in the embodiments of this application, before step 301 or 401 above, the PRS measurement method provided in the embodiments of this application may further include step 501 below.

[0515] In step 604 above, the activation information received by the UE includes at least one of the following: PRS processing window indication information; MG indication information; no MG activation indication information; and activation conditions. The activation conditions include at least one of a first activation condition, a second activation condition, and a third activation condition.

[0516] It should be noted that the descriptions of steps 601 to 604 can be found in the relevant descriptions in the above embodiments, and will not be repeated here.

[0517] This application provides another PRS measurement method, which may include the following steps 701 to 703.

[0518] Step 701: The second network-side device obtains the activation request message.

[0520] Step 703: The first network-side device receives the activation request message sent by the first network-side device.

[0521] The activation request message is used to request the activation of the target object; and when the target object is activated, it is used for PRS measurement.

[0522] In this embodiment of the application, the target object includes at least one of the following: target PRS processing window, target measurement interval MG.

[0523] It is understood that, in this embodiment of the application, the second electronic device obtaining the activation request message can specifically be receiving the activation request message sent by the UE.

[0525] Step 704: The second network-side device (UE) sends the target information.

[0526] The target information includes configuration information for at least one set of PRS processing windows.

[0527] It is understood that, in this embodiment of the application, the second electronic device may obtain the target information by receiving an activation request message sent by the first network-side device.

[0528] In the PRS measurement method provided in this application embodiment, since the second network-side device can send an activation request message to the first network-side device to request the activation of a target object, allowing the first network-side device to activate or deactivate the target object based on activation conditions, when another activation condition corresponding to the activation condition is configured / indicated to the UE, the UE can autonomously determine whether the target object is activated based on the activation condition it obtains, without requiring the first network-side device to send indication information indicating the activation behavior of the target object to the UE after activating or deactivating the target object. This saves signaling overhead.

[0529] The PRS measurement method provided in this application can be executed by a PRS measurement device. This application uses a PRS measurement device executing the PRS measurement method as an example to illustrate the PRS measurement device provided in this application.

[0532] This application provides a PRS measurement device. The PRS measurement device can directly determine whether a target object is active based on activation information.

Specifically, the determining module 32 is used to determine that all target PRS processing windows corresponding to the UE are activated when the UE meets the first activation condition; or, to determine that at least one PRS processing window corresponding to the UE is activated when the UE meets the second or third activation condition.

[0535] In one possible implementation, the activation condition includes a first activation condition. The determining module 32 is further configured to determine that all PRS processing windows are inactive if the UE does not meet the first activation condition.
