[0034] Figure 2 A flow chart of a positioning method in an embodiment of the present application is shown, and the method 200 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. Figure 2 As shown, the method may include the following steps.

[0035] S210, the terminal sends or receives first information.

[0036] In an embodiment of the present application, the first information includes: configuration information and / or activation information of a first positioning reference signal. The configuration information includes at least one of the following: activation state configuration information, reporting state configuration information, first time domain offset information, second time domain offset information, beam switching or quasi-co-location QCL switching configuration information; the activation information is used to activate the transmission of the first target positioning reference signal and / or to activate the reporting of the second target positioning reference signal, wherein the first target positioning reference signal includes one or more positioning reference signals in the first positioning reference signal, and the second target positioning reference signal includes one or more positioning reference signals in the first positioning reference signal.

[0037] In an embodiment of the present application, the first positioning reference signal is a positioning reference signal configured by the network side device for the terminal, including but not limited to: PRS, sounding reference signal (Sounding Reference Signal, SRS), channel state information reference information (Channel State Information Reference Signal, CSI-RS), tracking reference signal (Tracking Reference Signal, TRS) and synchronization signal and physical broadcast channel signal block (or synchronization signal block) (Synchronization Signal and PBCH Block, SSB).

[0038] In this embodiment, the first positioning reference signal may include multiple or multiple positioning reference signals, and the first target positioning reference signal activated by the activation information may be one or more positioning reference signals in the first positioning reference signal, and the second target positioning reference signal may be one or more positioning reference signals in the first positioning reference signal, wherein the first target positioning reference signal and the second target positioning reference signal may be the same or different, that is, the positioning reference signal sent by the activation information and the positioning reference signal reported for activation may be the same or different. For example, the network side device may activate the sending of 5 positioning reference signals in the first positioning reference signal and activate the reporting of 3 positioning reference signals in the 5 positioning reference signals according to specific needs. Among them, the activation information of the positioning reference signal sent for activation and the positioning reference signal reported for activation may be one or more, and may be the same activation information or different activation information.

[0039] S212: The terminal performs a positioning operation based on the first information.

[0040] In a possible implementation, the activation state configuration information may include at least one of the following:

[0041] (1) At least one first activation state information, wherein one first activation state information is associated with one or more first positioning reference signal groups, wherein the first positioning reference signal group includes at least one positioning reference signal among the first positioning reference signals.

[0042] That is, in this possible implementation, one first activation state information is associated with one or more first positioning reference signal groups. For example, in this possible implementation, one first activation state information is associated with one first positioning reference signal group, and one first positioning reference signal group includes one or more first positioning reference signals. The first activation state information is activated, which may indicate that all first positioning signals of the first positioning reference signal group are activated, or may indicate that one first positioning reference signal or a specific first positioning reference signal of the first positioning reference signal group is activated.

[0043] In another possible implementation, one of the first activation state information is associated with multiple first positioning reference signal groups, and each first positioning reference signal group includes one or more first positioning reference signals. The first activation state information is activated, which may indicate that the multiple first positioning reference signal groups are activated, or may indicate that the one first positioning reference signal group is activated or that one or more specific first positioning reference signal groups are activated. The first positioning signals of the activated first positioning reference signal group may also be one or more.

[0044] In addition, in this possible implementation, the association of one first activation state information with one or more first positioning reference signal groups also includes: including group identification information of the first positioning reference signal group in the first activation state information. And there can be N first activation state information, each value represents a first activation state. The group identification information of the first positioning reference signal group included in each first activation state information can be the same or different. In other words, one first positioning reference signal group can be associated with one or more first activation state information.

[0045] (2) at least one first activation state information, wherein one first activation state information is associated with a first positioning reference signal of one or more first unit resources; wherein the first unit resource includes at least the following: a positioning reference signal resource, a positioning reference signal resource set, a positioning reference signal resource corresponding to a TRP, and a positioning reference signal resource corresponding to a frequency layer.

[0046] That is to say, in this possible implementation, each first unit resource is configured with a first activation state information, and when one of the first activation state information is indicated in the activation information, the positioning reference signal corresponding to the first unit resource associated with the first activation state information is activated. For example, the first activation state information can be a specific value, such as 0, 1, 2, 3, where the first unit resource associated with 0 is the positioning reference signal resource corresponding to the positioning reference signal resource set (resource set) a, the first unit resource associated with 1 is resource set b, the first unit resource associated with 2 is the positioning reference signal resource corresponding to resource set c, and the first unit resource associated with 3 is the positioning reference signal resource corresponding to resource set d. If the downlink control information (Downlink Control Information, DCI) indicates that the value of the first activation state information is 1, it means that the positioning reference signal corresponding to resource set b is activated.

[0047] In another possible implementation, each first unit resource is configured with a first activation state information, and there may be multiple first unit resources corresponding to the same first activation state information. When the activation information indicates that one of the first activation state information is activated, it can be that one or a specific first positioning reference signal corresponding to the first unit resource associated with the first activation state information is activated, or it can be that all first positioning reference signals corresponding to the first unit resources associated with the first activation state information are activated. For example, the first activation status information can be a specific value, such as 0, 1, 2, or 3, where the first unit resource associated with 0 is positioning reference signal resource set a1, positioning reference signal resource set a2, and positioning reference signal resource set a2; the first unit resource associated with 1 is resource set b1, resource set b2, and resource set b3; the first unit resource associated with 2 is the positioning reference signal resource corresponding to resource set c; and the first unit resource associated with 3 is the positioning reference signal resource corresponding to resource set d. If the downlink control information (DCI) indicates that the value of the first activation status information is 1, it can indicate activation of resource set b1, resource set b2, and resource set b3, or one of them, such as resource set b1, or multiple ones, such as resource set b1 and resource set b2, can be activated according to the protocol or other configuration signaling.

[0048] (3) At least one first activation state table, wherein the first activation state table is used to record an association relationship between the first activation state information and the first positioning reference signal group.

[0049] In this possible implementation, the first activation state information is a list, and each member of the list is associated with one or more first positioning reference signal groups. Each member in the list indicates a first activation state information, which can be a specific value or an identifier, and the specific embodiment of the present application is not limited. The one or more first positioning reference signal groups associated with each member can be indicated by a positioning reference signal group identifier, or can also be indicated by an identifier of one or a group of first unit resources.

[0050] For example, optionally, one or more first positioning reference signal groups may be associated with one or a group of first sets, where the first set may include a positioning reference signal reporting set and / or a positioning reference signal resource set.

[0051] In a possible implementation, the first positioning reference signal group or the first activation state table may also include identification information and / or configuration information of a third positioning reference signal group, wherein the third positioning reference signal group is a subset of the first positioning reference signal group, that is, the third positioning reference signal group may include some or all of the positioning reference signals in the first positioning reference signal group.

[0052] In this possible implementation, the identification information may be the identification information of the first positioning reference signal group, for example, the identification information of one or more positioning reference signal groups associated with a member is recorded in the first activation state table. Alternatively, the identification information may also be the identification information of the third positioning reference signal group, for example, a table entry is added to the first activation state table to record the identification information of the third positioning reference signal group, or the identification information of the third positioning reference signal group is added to the configuration information of the first positioning reference signal group. Alternatively, the identification information may also be the identification information of the first positioning reference signal group and the identification information of the second positioning reference signal group, for example, the identification information of the associated one or more first positioning reference signal groups and the identification information of the third positioning reference signal group of the corresponding first positioning reference signal group are recorded under each member of the list in the first activation state table. Alternatively, when a first activation state information is associated with one or more first positioning reference signal groups, and the first positioning reference signal group is associated with one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets, the identification information may also indicate the identification information of a specific positioning reference signal in one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets associated with the activation of the first activation state information. Alternatively, when a first activation state information is associated with a first positioning reference signal group, the identification information may be an identifier of one or a specific positioning reference signal of the first positioning reference signal group; or, when a first activation state information is associated with multiple first positioning reference signal groups, the identification information may be an identifier of one or a specific first positioning reference signal group; wherein, in one embodiment, the one or a specific first positioning reference signal group or the one or a specific first positioning reference signal belongs to a third positioning reference signal group or includes a third positioning reference signal group.

[0053] In this possible implementation, the configuration information of the third positioning reference signal group may be positioning reference signal resource information or a configuration window corresponding to the third positioning reference signal group, etc. The terminal may determine the resources for detecting the third positioning reference signal group according to the third positioning reference signal group. It is worth noting that the resource for detecting the third positioning reference signal group may be determined to determine the positioning reference signal of the third positioning reference signal group, or to determine the configuration information of the third positioning reference signal group, or to determine how to detect the signal of the third positioning reference signal group. The understanding may also be used for other similar descriptions.

[0054] In addition, the configuration information of the third positioning reference signal group may include at least one of the following: period; silence parameter; number of repetitions; offset within the period; bandwidth information; frequency domain offset information; time information; spatial direction indication information; transmission configuration indication TCI indication information; quasi-co-site QCL indication information; beam indication information; power information; MG configuration information; type of positioning reference signal; BWP information; sending; stop sending; activation deactivation flag; parameter set numerology; time offset information (for example, cell time offset and / or TRP time offset); the terminal detects the third positioning reference signal according to the configuration information of the third positioning reference signal group.

[0055] In another possible implementation scheme, the third positioning reference signal group is equal to the first positioning reference signal group, and the terminal determines to detect the signal of the first positioning reference signal group according to configuration information of the third positioning reference signal group.

[0056] For example, if the configuration information is a configuration window for a third positioning reference signal group, the terminal can detect the positioning reference signal in the third positioning reference signal group from different TRPs on the time domain resources corresponding to the configuration window, thereby quickly detecting the positioning reference signal in the third positioning reference signal group from different TRPs.

[0057] Alternatively, the configuration information of the third positioning reference signal group may include at least one of the following:

[0058] The window length of the configuration window;

[0059] The time domain offset information and / or period information of the configuration window

[0060] The configuration information of the positioning reference signal of the third positioning reference signal group relative to the configuration window; for example, the offset of the third positioning reference signal relative to the starting position of the configuration window, or the time offset of the third positioning reference signal relative to the starting position of the configuration window calculated according to the window length, or the other configuration information mentioned above, such as the period of the signal; the silence parameter, etc.

[0061] When a first activation state information is associated with one or more first positioning reference signal groups, and the first positioning reference signal is associated with one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets, when activated, a specific positioning reference signal can be selected from one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets for activation, that is, a specific positioning reference signal resource set, a positioning reference signal corresponding to a specific frequency layer, or a positioning reference signal corresponding to a specific positioning reference signal resource, etc. are selected from a positioning reference signal reporting set and / or a positioning reference signal resource set associated with a first activation state information. The specific positioning reference signal can also be indicated by the identification information included in the above-mentioned first positioning reference signal group or the third positioning reference signal group or the first activation state table, or can also be indicated by a high-level signaling indication or a protocol.

[0062] For example, if one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets contain multiple positioning reference signal resource sets (sets) or multiple positioning reference signal resources (resource) or multiple frequency layers of one TRP, the network side device may activate only one or part of the positioning reference signal resource sets / positioning reference signal resource / frequency layers for sending / reporting, for example, by indicating through high-level signaling which specific positioning reference signal to activate, that is, indicating a specific positioning reference signal resource set / positioning reference signal resource / frequency layer.

[0063] For another example, if one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets contain one or more positioning reference signal resource sets (sets) or one or more positioning reference signal resources (resource) or one or more frequency layers of multiple TRPs, the network side device may activate only some, specific or all of the TRPs, but the positioning reference signal resource set / positioning reference signal resource / frequency layer may indicate through high-level signaling or requirements which specific set, resource, or frequency layer to activate.

[0064] For another example, when a first activation state information is associated with one or more first positioning reference signal groups, and the first positioning reference signal group is associated with one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets, all positioning signals in the positioning reference signal reporting set or the positioning reference signal set can be activated by one activation signaling.

[0065] In the above possible implementations, the specific positioning reference signal may be one of the following: an aperiodic positioning reference signal, a semi-static positioning reference signal, and a demand-based positioning reference signal. The demand-based positioning reference signal may be an aperiodic positioning reference signal or a semi-static positioning reference signal, which is not specifically limited in this embodiment.

[0066] In addition, in the above possible implementation manner, the specific positioning reference signal may also be one or a group of positioning reference signals, and the group of PRSs (which may be called a trigger group) may have at least one of the following characteristics:

[0067] Same time domain type (periodic, aperiodic, semi-static);

[0068] Same BWP-ID;

[0069] Same frequency layer;

[0070] The same time domain parameters, wherein the time domain parameters may include at least one of the following: period, slot offset, muting, and repetition

[0071] Belonging to the same positioning reference signal resource set;

[0072] A collection of objects belonging to the same activation group;

[0073] Same group ID;

[0074] The same resource parameters, wherein the resource parameters include at least one of the following: beam, beamgroup, resource set ID, resource ID, and QCL information;

[0075] Belonging to one or more first unit resources, wherein the first unit resource includes one of the following: a positioning reference signal resource, a positioning reference signal resource set, a positioning reference signal resource corresponding to a TRP (also referred to as a TRP), and a positioning reference signal resource corresponding to a frequency layer (also referred to as a frequency layer);

[0076] Have the same reporting type;

[0077] Same reporting configuration;

[0078] Same measurement type;

[0079] Same measurement configuration;

[0080] Belong to the same reporting group;

[0081] belong to the same measurement group.

[0082] In a possible implementation, similar to the activation state configuration information, the reporting state configuration information may also include at least one of the following:

[0083] (1) at least one second activation state information, wherein one second activation state information is associated with one or more second positioning reference signal groups, wherein the second positioning reference signal group includes at least one positioning reference signal in the first positioning reference signal.

[0084] That is, in this possible implementation, one second activation state information is associated with one or more second positioning reference signal groups. For example, in this possible implementation, one second activation state information is associated with one second positioning reference signal group, and one second positioning reference signal group includes one or more first positioning reference signals. The second activation state information is activated, which may indicate that all first positioning signals of the second positioning reference signal group are activated for reporting, or may indicate that one first positioning reference signal or a specific first positioning reference signal of the second positioning reference signal group is activated for reporting.

[0085] In another possible implementation, one second activation state information is associated with multiple second positioning reference signal groups, each of which includes one or more first positioning reference signals. The second activation state information is activated, which may indicate that the multiple second positioning reference signal groups are activated for reporting, or may indicate that the one second positioning reference signal group is activated for reporting, or that one or more specific second positioning reference signal groups are activated for reporting. The first positioning signal of the activated second positioning reference signal group may also be one or more.

[0086] In addition, in this possible implementation, the association of one second activation state information with one or more second positioning reference signal groups also includes: including group identification information of the second positioning reference signal group in the second activation state information. And there can be N second activation state information, each value represents a second activation state. The group identification information of the second positioning reference signal group included in each second activation state information can be the same or different. In other words, one second positioning reference signal group can be associated with one or more second activation state information.

[0087] For example, there may be N second activation state information, each value representing a type of second activation state information, and the positioning reference signal of the same second activation state information may be triggered for reporting and / or configured with reporting resources at the same time, for example, may be triggered by "PRS-request" or "PRS report request".

[0088] For another example, in some scenarios, there is second activation state information and first state activation information, but in some scenarios, the second activation state information is both the second activation state information and the first activation state information. For example, the second activation state information can be used to indicate state information sent by a non-periodic positioning reference signal, and can also be used to indicate state information reported by a non-periodic positioning reference signal.

[0089] In a possible embodiment, the second positioning reference signal group may be a combination of positioning reference signals that need to be reported in the corresponding activation state, or may be the first positioning reference signal group, that is, a combination of positioning reference signals that need to be sent in the corresponding activation state.

[0090] (2) at least one second activation state information, wherein one second activation state information is associated with one or more first positioning reference signals corresponding to the first unit resources.

[0091] For example, a second activation state information may be configured for each first unit resource. In this case, the second activation state information may be a specific value, such as 0, 1, 2, or 3. For example, when the field corresponding to the second activation state information in the DCI takes a corresponding value, it indicates that the positioning reference signal corresponding to the first unit resource associated with the value is activated for reporting. The activation report may be understood as activation reporting, or activation reporting and sending, and a similar understanding applies to other places in the embodiments of the present application.

[0092] In another possible implementation, each first unit resource is configured with a second activation state information, and there may be multiple first unit resources corresponding to the same second activation state information. When the activation information indicates that one of the second activation state information is activated, it can be that one or a specific first positioning reference signal corresponding to the first unit resource associated with the second activation state information is activated, or it can be that all first positioning reference signals corresponding to the first unit resources associated with the second activation state information are activated. For example, the second activation state information can be a specific value, such as 0, 1, 2, or 3, where the first unit resource associated with 0 is positioning reference signal resource set a1, positioning reference signal resource set a2, and positioning reference signal resource set a2; the first unit resource associated with 1 is resource set b1, resource set b2, and resource set b3; the first unit resource associated with 2 is the positioning reference signal resource corresponding to resource set c; and the first unit resource associated with 3 is the positioning reference signal resource corresponding to resource set d. If the downlink control information (DCI) indicates that the value of the second activation state information is 1, it can indicate activation of resource set b1, resource set b2, and resource set b3, or one of them, such as resource set b1, or multiple ones, such as resource set b1 and resource set b2, can be activated according to the protocol or other configuration signaling.

[0093] (3) At least one second activation state table, wherein the second activation state table is used to record an association relationship between the second activation state information and the second positioning reference signal group.

[0094] In this possible implementation, each member of the second activation state table is associated with one or more second positioning reference signal groups. Optionally, a second positioning reference signal group may be associated with one or more second sets, and the second set is associated with one or a group of the first sets.

[0095] In a possible implementation, the second positioning reference signal group or the second activation state table may also include identification information and / or configuration information of a fourth positioning reference signal group, wherein the fourth positioning reference signal group is a subset of the second positioning reference signal group, that is, the fourth positioning reference signal group may include some or all of the positioning reference signals in the second positioning reference signal group.

[0096] In this possible implementation, the identification information may be the identification information of the second positioning reference signal group, for example, the identification information of one or more positioning reference signal groups associated with a member is recorded in the second activation state table. Alternatively, the identification information may also be the identification information of the fourth positioning reference signal group, for example, a table entry is added to the second activation state table to record the identification information of the fourth positioning reference signal group, or the identification information of the fourth positioning reference signal group is added to the configuration information of the second positioning reference signal group. Alternatively, the identification information may also be the identification information of the second positioning reference signal group and the identification information of the second positioning reference signal group. For example, the second activation state table records the identification information of one or more associated second positioning reference signal groups and the identification information of the fourth positioning reference signal group of the corresponding second positioning reference signal group under each member of the list. Alternatively, when a second activation state information is associated with one or more second positioning reference signal groups, and the second positioning reference signal group is associated with one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets, the identification information may also indicate the identification information of a specific positioning reference signal in one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets associated with the second activation state information activation. Alternatively, when a second activation state information is associated with a second positioning reference signal group, the identification information may be an identifier of one or a specific positioning reference signal of the second positioning reference signal group; or, when a second activation state information is associated with multiple second positioning reference signal groups, the identification information may be an identifier of one or a specific second positioning reference signal group; wherein, in one embodiment, the one or a specific second positioning reference signal group or the one or a specific first positioning reference signal belongs to a fourth positioning reference signal group or includes a fourth positioning reference signal group.

[0097] In this possible implementation, the configuration information of the fourth positioning reference signal group may be positioning reference signal resource information or a configuration window corresponding to the fourth positioning reference signal group, etc. The terminal may determine the resources for detecting the fourth positioning reference signal group according to the fourth positioning reference signal group. It is worth noting that the resource for detecting the fourth positioning reference signal group may be determined to determine the positioning reference signal of the fourth positioning reference signal group, or to determine the configuration information of the fourth positioning reference signal group, or to determine how to detect the signal of the fourth positioning reference signal group. The understanding may also be used for other similar descriptions.

[0098] In addition, the configuration information of the fourth positioning reference signal group may include at least one of the following: period; silence parameter; number of repetitions; offset within the period; bandwidth information; frequency domain offset information; time information; spatial direction indication information; transmission configuration indication TCI indication information; quasi-co-site QCL indication information; beam indication information; power information; MG configuration information; type of positioning reference signal; BWP information; sending; stop sending; activation deactivation flag; parameter set numerology; time offset information (for example, cell time offset and / or TRP time offset); the terminal detects the third positioning reference signal according to the configuration information of the fourth positioning reference signal group.

[0099] In another possible implementation scheme, the fourth positioning reference signal group is equal to the second positioning reference signal group, and the terminal determines to detect signals of the second positioning reference signal group according to configuration information of the fourth positioning reference signal group.

[0100] For example, if the configuration information is a configuration window for the fourth positioning reference signal group, the terminal can detect the positioning reference signal in the fourth positioning reference signal group from different TRPs on the time domain resources corresponding to the configuration window, thereby quickly detecting the positioning reference signal in the fourth positioning reference signal group from different TRPs; for another example, if the configuration information is a configuration window for the fourth positioning reference signal group, the terminal can send the measurement result of the fourth positioning reference signal group or the second positioning reference signal group on the time domain resources corresponding to the configuration window.

[0101] Alternatively, the configuration information of the fourth positioning reference signal group may include at least one of the following:

[0102] The window length of the configuration window;

[0103] The time domain offset information and / or period information of the configuration window

[0104] The configuration information of the positioning reference signal of the fourth positioning reference signal group relative to the configuration window; for example, the offset of the fourth positioning reference signal relative to the starting position of the configuration window, or the time offset of the fourth positioning reference signal relative to the starting position of the configuration window calculated according to the window length, or the other configuration information mentioned above, such as the period of the signal; the silence parameter, etc.

[0105] When a second activation state information is associated with one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets, when activating reporting and / or measurement, a specific positioning reference signal can be selected from one or a group of positioning reference signal reporting sets and / or positioning reference signal resource sets for reporting and / or measurement, that is, a specific positioning reference signal resource set, a positioning reference signal corresponding to a specific frequency layer, or a positioning reference signal corresponding to a specific positioning reference signal resource, etc. are selected from a positioning reference signal reporting set and / or positioning reference signal resource set associated with a second activation state information. The specific positioning reference signal can also be indicated by identification information included in the above-mentioned second positioning reference signal group or second activation state table, or can also be indicated by high-layer signaling.

[0106] In a possible implementation, the specific positioning reference signal may have the same characteristics as the specific positioning reference signal activated by the activation state configuration information. For details, please refer to the above description, which will not be repeated here.

[0107] In this embodiment, the second activation state information may indicate activation of reporting of positioning reference signals in the second positioning reference signal group, or measurement and reporting. Optionally, the second activation state information may also be used to indicate reporting of measurement information of a fifth positioning reference signal group. The fifth positioning reference signal group may include one of the following:

[0108] (1) A first specific positioning reference signal, wherein the first specific positioning reference signal is part or all of the positioning reference signals in the second positioning reference signal group. That is, when an activation state information instructs the terminal to measure the positioning reference signals in the second positioning reference signal group, it can also instruct the terminal to report the measurement information of part or all of the positioning reference signals therein.

[0109] (2) A second specific positioning reference signal, wherein the second specific positioning reference signal is part or all of the positioning reference signals in the fourth positioning reference signal group.

[0110] (3) A collection of the first specific positioning reference signal and other positioning reference signals, wherein the other positioning reference signals are positioning reference signals outside the second positioning reference signal group. For example, if the positioning reference signals in the second positioning reference signal group are non-periodic positioning reference signals, then the other positioning reference signals may be periodic positioning reference signals.

[0111] In the above possible implementation manner, optionally, the measurement information may include at least one of the following:

[0116] Identification information of the positioning reference signal;

[0117] Location information;

[0118] Relative position information.

[0119] In a possible implementation, the first activation state information and the second activation state information may be the same or different. For example, the first activation state table and the second activation state table may be the same table, and each member may be associated with one or more first positioning reference signal groups and one or more second positioning reference signal groups. Optionally, the first positioning reference signal group and the second positioning reference signal group associated with the same member in the activation state table may be the same or different, for example, the second positioning reference signal group associated with the same member may be part or all of the positioning reference signals in the first positioning reference signal group.

[0120] In a possible implementation, the first activation state table and / or the second activation state table may include multiple activation state tables. For example, the first activation state table and / or the second activation state table includes at least one of the following:

[0122] (2) a non-periodic activation state table, wherein the first positioning reference signal in the non-periodic activation state table is a non-periodic positioning reference signal; that is, in the non-periodic activation state table, the positioning reference signal associated with the activation state information (including the first activation state information and / or the second activation state information) is a non-periodic positioning reference signal.

[0123] (3) A demand-based activation state table, wherein the first positioning reference signal in the demand-based activation state table is a demand-based positioning reference signal. That is, in the demand-based activation state table, the positioning reference signal associated with the activation state information (including the first activation state information and / or the second activation state information) is a demand-based positioning reference signal. The demand-based positioning reference signal may be a semi-static positioning reference signal or an aperiodic positioning reference signal.

[0124] It is worth noting that the functions of the different activation state tables may be the same or different. For example, the activation state information in the non-periodic activation state table may be used to activate the sending of the positioning reference signal and the reporting of the measurement result, whereas the activation state information in the semi-static activation state table may only be used to activate the sending of the positioning reference signal or the reporting of the measurement result. It may also be any combination of the above statements, which will not be described one by one here.

[0125] In the above possible implementations, optionally, the first activation state table and / or the second activation state table may also record: first indication information, used to indicate that the first activation state table or the second activation state table is used for activation sending and / or for activation reporting. That is, each activation state table records the first indication information to indicate whether the activation state table is used for activation sending or for activation reporting, or for both activation sending and activation reporting.

[0126] In the above possible implementation methods, optionally, the first activation state table and / or the second activation state table may also record: second indication information, used to indicate that the first activation state table or the second activation state table is a semi-static activation state table, a non-periodic activation state table, or a demand-based activation state table.

[0249] In this possible implementation, other positioning reference signals and the first positioning reference signal have a time slot offset relative to the first positioning reference signal (which may be the first positioning reference signal activated at the same time, or the first positioning reference signal resource / positioning reference signal resource set / positioning reference signal resourcesetting / TRP / frequency layer / per trigger list in the positioning reference signal group). For example, if the first time domain offset information is configured based on per resource set (that is, the second unit resource is a positioning reference signal resource set), the first time domain offset information also includes the time domain offset of each resource in the resource set relative to the resource set. For another example, if the first time domain offset information is configured per resource setting (that is, the second unit resource is a positioning reference signal resource set), the first time domain offset information also includes the time domain offset of each positioning reference signal resource or positioning reference signal resource set relative to the resourcesetting.

The configuration information of the second configuration window is analogous to the configuration information of the first configuration window, so the positioning reference signal in the second configuration window may also be configured in the same manner as the positioning reference signal of the first configuration window.

[0256] In this possible implementation, the window length information of the first configuration window may also be configured. In this possible implementation, the network side device may determine during configuration that the positioning reference signal to be measured is within the window of the first configuration window.

[0257] It is worth noting that the above-mentioned first time domain offset can be configured through one configuration information, or can be configured through multiple configuration information, or can be configured through activation information and configuration information.

Of course, it is not limited to this. In practice, it can also be other operation results with the activation time of the first positioning reference signal and the first time domain offset information of the first positioning reference signal as parameters. For example, the sum function of the activation time of the first positioning reference signal and the first time domain offset information of the first positioning reference signal corresponding to the numerology of the receiving activation command, and for another example, the sum function of the activation time of the first positioning reference signal and the first time domain offset information of the first positioning reference signal corresponding to the numerology of the sending of the reporting information.

[0364] Optionally, before receiving and measuring the first target positioning reference signal activated by the positioning reference signal request activation information, the method further includes: if a first BWP for sending the first DCI is different from a target BWP for sending the first target positioning reference signal, and the first BWP is in an activated state, performing one of the following:

[0365] Receiving instruction information for switching to a target BWP;

[0366] Receiving instruction information for activating the target BWP;

[0367] Receive configuration information of the target MG;

[0368] Switch to a state that supports two active BWPs at the same time;

[0369] Switch to the first target configuration window;

[0370] The target BWP is activated.

[0371] In a possible implementation manner, receiving and measuring the first target positioning reference signal activated by the positioning reference signal request activation information may include: if the activated first target positioning reference signal comes from a neighboring cell of the terminal, and the first time domain offset information of the first target positioning reference signal is configured relative to the activation command sent by the serving cell, performing at least one of the following actions:

[0372] Determine a reception time and / or a transmission time of the first target positioning reference signal in a neighboring cell;

[0373] Determine a reception time and / or a transmission time of the first target positioning reference signal in a serving cell;

[0374] Determine an association relationship between the first target positioning reference signal generation sequence and a reception time and / or a transmission time of the neighboring cell;

[0375] Determine an association between a generation sequence of the first target positioning reference signal and a reception time and / or a transmission time of the serving cell.

[0376] For example, if the activated first target positioning reference signal comes from a neighboring cell of the terminal, and the neighboring cell is not synchronized with the serving cell, when receiving and measuring the first target positioning reference signal, if the first time domain offset information of the first target positioning reference signal is configured relative to the activation command sent by the serving cell, then by determining at least one of the above, the terminal can generate a corresponding sequence for detection and measurement.

[0377] In another possible implementation manner, receiving and measuring the first target positioning reference signal activated by the positioning reference signal request activation information may include: if the activated first target positioning reference signal comes from a neighboring cell of the terminal, and the first time domain offset information of the first target positioning reference signal is offset information relative to the neighboring cell, performing at least one of the following actions:

[0378] Determine a reception time and / or a transmission time of the first target positioning reference signal in a neighboring cell;

[0379] Determine a reception time and / or a transmission time of the first target positioning reference signal in a serving cell;

[0380] Determine an association relationship between the first target positioning reference signal generation sequence and a reception time and / or a transmission time of the neighboring cell;

[0381] Determine an association between a generation sequence of the first target positioning reference signal and a reception time and / or a transmission time of the serving cell.

[0382] In a specific application, the activated positioning reference signal may come from a serving cell or a neighboring cell. When there is a first target positioning reference signal from a neighboring cell (TRP), and the TRP is not synchronized with the serving cell, then:

[0383] 1. The configuration information in the first information further includes time offset information s1 between the TPR and the serving cell, the reference cell, or one of the serving cell and the reference cell, such as SFN0, absolute time or slot offset 3;

[0384] 2. The activation information in the first information also includes real-time cell time offset information s2. The cell time offset information s2 can be an absolute value or a difference value from the time offset information s1.

[0385] The network side device can configure the above information 1 and 2 to the terminal through LPP\RRC\broadcast message, or update the terminal through MAC CE.

[0386] Optionally, there are the following two possibilities for receiving and measuring the first time domain offset of the first target positioning reference signal sent by the neighboring cell:

[0387] (1) The first time domain offset configured for the first target positioning reference signal is time N relative to the activation command (DCI or HARQ carrying MAC CE, RRC, LPP) of the serving cell.

[0388] Then the resource for generating or sending the first target positioning reference signal of the neighboring cell at the time of the neighboring cell is: Function (N, time offset information s1, time offset information s2, slot offset).

[0389] For example, when the time offset information s1 is the time offset between the TRP and the service cell of the activation command, and the time offset information s2 is the dynamic difference between the time offset between the TRP and the service cell of the activation command relative to the time offset information s1, the sending time of the PRS of the neighboring cell = N+s1+s2+slot offset.

[0390] If the time offset information contains a non-slot integer part, the sending time may be rounded up or down at a time slot or symbol level, optionally.

[0391] Wherein, if the calculated transmission time is rounded up or down, the UE expects the configured measurement window to take the offset information into account;

[0392] (2) The first time domain offset configured by the first target positioning reference signal is the time N relative to the neighboring cell.

[0393] Then the resource for generating or sending the PRS of the neighboring cell in the serving cell is: Function (N, time offset information s1, time offset information s2, slot offset).

[0394] For example, the UE's expected reception time or configuration time for receiving the neighboring cell PRS is the time n+slotoffset on the serving cell, and the actual transmission time of the neighboring cell PRS is: N+s1+s2+slot offset.

[0395] In the above possible implementations, if the signal is not rounded at the upper and lower symbol or slot levels, the extended symbol (since it is sent starting from the boundary position) also needs to have no other data or signals sent.

[0396] In the foregoing possible implementation manner, optionally, the sequence of the neighboring cell PRS may include one of the following:

[0397] (1) The slot / symbol sequence number of the serving cell is generated according to the activation command.

[0398] (2) Generated based on the sequence number of the slot / symbol sent by the neighboring cell.

[0399] Among them, if it is generated according to the sequence number of the slot / symbol sent by the neighboring cell, the serving cell or LMF needs to notify the neighboring cell of at least one of the following information:

[0400] (1) Activation time: absolute time / activation time of neighboring cell / activation time of serving cell;

[0401] (2) time offset information s1 between the serving cell / reference cell and the neighboring cell;

[0402] (3) Service cell identification information.

[0403] Optionally, if the sequence is generated according to the slot / symbol of the neighboring cell, the UE determines the slot / symbol of the neighboring cell according to the first target positioning reference signal reception time when generating the local sequence.

[0404] In one possible implementation, one or more downlink signalings may be used to activate multiple target objects, wherein the downlink signaling includes: the first DCI or the first MAC CE, and the target objects include: the first target positioning reference signal, the target BWP, the target MG, and the first target configuration window.

[0405] Optionally, different downlink signaling may be used to activate or deactivate different types of the first target positioning reference signals; for example, the first DCI for activating different types of first target positioning reference signals is different, or the first DCI for activating the same type of first target positioning reference signal and the first DCI for deactivating the same type of first target positioning reference signal are different. The different types of first target positioning reference signals include: a periodic positioning reference signal, a semi-static positioning reference signal, a non-periodic positioning reference signal, or an on-demand positioning reference signal.

[0406] Alternatively, optionally, different fields of the same downlink signaling may be used to activate or deactivate different types of the first target positioning reference signals; or different information in the same field of the same downlink signaling may be used to activate or deactivate different types of the first target positioning reference signals; wherein the downlink signaling includes: the first DCI or the first MAC CE.

[0407] In each of the foregoing possible implementations, if there are multiple first DCIs, at least one of the following conditions is met:

[0408] (1) The first DCI activating the target BWP switching is no later than the first DCI activating the first target positioning reference signal;

[0409] (2) Between the sending of the first DCI for activating the first target positioning reference signal and the sending of the first target positioning reference signal, no command for switching the BWP is allowed;

[0410] (3) If the first activated target positioning reference signal exists on multiple target BWPs or target carriers, the first DCI activated to switch to the target BWP or target carrier is no later than the first target positioning reference signal on the BWP or carrier;

[0411] (4) If the activated first target positioning reference signal exists on one or more target frequency layers, the DCI of activating the target MG is no later than the first target positioning reference signal.

[0503] In one possible implementation, before the terminal sends or receives the first information, the method further includes: the terminal reports capability information, wherein the capability information indicates that the activation time of the positioning reference signal that the terminal expects to configure is not less than the first threshold time. Through this possible implementation, the network side can be informed of the capability of the terminal, so that a suitable target QCL can be configured for the terminal to avoid measurement failure of the positioning reference signal.

[0504] In the above possible implementation manner, determining a first threshold time for beam or QCL switching corresponding to the first target positioning reference signal may include:

[0505] The first threshold time is determined according to target information; wherein the target information includes at least one of the following: a second threshold time of configuration information of the beam or QCL switching of the first target positioning reference signal; a pre-agreed third threshold time; and capability information of the terminal.

[0506] In the embodiment of the present application, optionally, the positioning reference signal may have at least one of the following characteristics:

[0507] 1. If the positioning reference signal is a non-periodic positioning reference signal, the type of positioning reference signal reporting can only be non-periodic;

[0508] 2. If the positioning reference signal is a semi-static positioning reference signal, the type of positioning reference signal reporting is semi-static or aperiodic;

[0510] 5. Positioning reference signals under the same activation state information or that can be activated by a DCI command have the same time domain type (eg, periodic, non-periodic, semi-static, on demand).

[0511] In the embodiment of the present application, optionally, if the bandwidth configured by the first target positioning reference signal is greater than the BWP, the UE may perform one of the following actions:

[0512] Only measure the first target positioning reference signal within the BWP;

[0513] measuring a first target positioning reference signal within a window of the MG;

[0515] Optionally, the activation of the first target positioning reference signal, and / or the BWP switching or the frequency layer switching may have one of the following characteristics:

[0516] Perform positioning reference signal activation and BWP / frequency layer switching within one DCI;

[0517] Performing positioning reference signal deactivation within a DCI; when deactivating, it may implicitly indicate switching the BWP to the default BWP, or activating the BWP, or it may also explicitly indicate BWP switching;

[0518] Positioning reference signal activation and BWP activation for positioning are performed within one DCI; in this case, two BWPs can be activated simultaneously in one cell, and the UE can determine the priority or process them simultaneously according to the protocol or network side indication;

[0519] Activate the positioning reference signal and switch the BWP in different DCIs; the DCI for performing the BWP switch must be no later than the positioning reference signal for performing the positioning reference signal activation; there must not be a BWP switch command between the activation of the positioning reference signal and the first positioning reference signal measurement, or the UE does not process the BWP switch command;

[0520] If no MG is configured, the UE is not expected to process positioning reference signals beyond the activated BWP;

[0521] The UE does not expect to receive multiple signalings containing PRS-request in one slot;

[0522] The BWP / frequency layer of a trigger state activated by PRS-request is the same or the BWP / frequency layer of a positioning reference signal resource setting is the same; or the BWP / frequency layer of a positioning reference signal report setting is the same;

[0523] If the BWP / frequency layer of the positioning reference signal of a trigger state activated by PRS-request is different, the UE may have one of the following behaviors: requesting the MG or configuring the MG, optionally supporting different BWP or frequency layer measurements under the MG; only measuring the positioning reference signal of the activated BWP; requesting reconfiguration.

[0524] In one possible implementation, PRS-request can be used to activate multiple UEs to perform positioning reference signal measurements. The required UEs blindly detect whether the DCI contains a specific RNTI. If the UE does not detect the DCI carrying PRS-request in N consecutive slots after sending the request information for the positioning reference signal, or the current positioning reference signal activated with PRS-request does not meet the UE's needs, the UE initiates a new positioning reference signal activation or request.

[0525] In a possible implementation, before receiving the first information, the method may further include: the terminal reporting capability information, wherein the capability information includes at least one of the following:
