To facilitate a better understanding of the embodiments of the present application, the related positioning technologies of the present application are described.

Positioning technology is one of the core technologies of modern communication systems and navigation systems, such as satellite navigation systems, Bluetooth, WiFi, etc., all provide positioning functions. Similarly, modern cellular communication systems also support positioning functions. Starting from 3G and 4G (LTE) systems, various advanced positioning technologies are gradually added to cellular communication systems. In the 5G (NR) system, the positioning technology will also be supported, and the specific standard was introduced in Release 16 (Release 16, R16). In NR in 3GPP R16, the following positioning technologies are introduced:

Downlink Time Difference of Arrival (DL-TDOA);

Uplink Time Difference of Arrival (UL-TDOA);

Multiple round trip time positioning method (Multi Round Trip Time, Multi-RTT);

Downlink Angle of Departure (DL-AoD);

Uplink Angle of Arrival (UL-AoA);

Enhanced cell identification (ID) positioning method.

In order to support various positioning methods, R16NR introduces a Positioning Reference Signal (PRS) in the downlink and an SRS for positioning (SRS for positioning) in the uplink.

Among them, the Multi Round Trip time (Multi-RTT) positioning technology requires both the transmitting and receiving point (Transmission reception point, TRP) and the UE to measure the time difference (Rx-Tx time difference). As shown in Figure 2 below, the TRP sends the downlink (downlink, DL) PRS at time T1. After channel propagation, the UE receives the PRS signal at time T2, and sends the uplink (uplink, UL) SRS signal at time T3. Correspondingly, The TRP will receive the SRS signal at time T4. TRP will calculate the time difference T4-T1 (positive in this example), and the UE will also calculate the time difference T2-T3 (negative in this example), these two time differences are added together to get twice the propagation time , the distance between the TRP and the UE can be calculated according to the time, and the position of the UE can be determined by combining the distance information between multiple TRPs and the UE.

When the radio access network 4 (Radio Access Network 4, RAN4) locates and measures the time difference between sending and receiving, the influence of the positional relationship between the SRS and the PRS in the time-frequency domain on the measurement results is discussed. From the frequency domain point of view, when the PRS and SRS are in different frequency bands (bands), the measurement may be caused by different uplink timing (UL timing)/RF chain (RF chain)/antenna physical locations on different bands, etc. The results are different; from the time domain point of view, if the PRS and SRS used for measurement are far apart in the time domain, measurement errors may be caused by UE movement or clock deviation.

In addition, there are some limitations in the transmission of SRS. For example, SRS only supports transmission on the UL active (active) BWP, and considering the power consumption and complexity of the UE, discontinuous reception (RRC) in the RRC connected state is not expected at present. -Transmit periodic SRS and semi-persistent SRS signals in the state of Connect Discontinuous Reception, C-DRX).

At present, PRS only supports periodic transmission, and semi-persistent PRS and aperiodic PRS may be introduced in the future. The transmission method of SRS signal is introduced below. The SRS used for positioning is likely to follow the following method, which also has certain reference significance for PRS signal:

Periodic SRS: The period and time domain offset of the SRS signal are configured through radio resource control (Radio Resource Control, RRC) signaling, and the UE performs periodic transmission according to a fixed position.

Semi-persistent SRS: Configure the period and time domain offset of the SRS signal through RRC signaling, and then activate and deactivate through the Media Access Control Control Element (MAC CE). The period and time domain offset are the same as the periodic SRS, and the signaling structure of the MAC CE is shown in Figure 3.

Aperiodic SRS: RRC signaling is configured with a triggering offset, which can be triggered by the SRS request field in DCI format 0_1, DCI format 1_1, and DCI format 2_3. 2-bit information is used in the DCI to represent the triggered SRS resource group. Wherein, 00 indicates that no aperiodic SRS resource will be triggered, and 01/10/11 indicates that one or more SRS resource triggers with aperiodic SRS-ResourceTrigger value of 1/2/3 in the high-layer signaling respectively are triggered.

Among them, the explanation of the parameters in the MAC CE shown in Figure 3 is as follows:

A/D: indicates whether the corresponding SRS resource set is activated or deactivated, set to 1 to indicate activation, and set to 0 to indicate deactivation;

The cell identifier (SRS Resource Set's Cell ID) of the SRS resource set: the serving cell (serving cell) containing the SRS resource set (SRS Resource Set) that needs to be activated/deactivated;

The BWP identifier (SRS Resource Set's BWP ID) of the SRS resource set: corresponding to the indicated bandwidth part (Band Width Part, BWP) in the downlink control information (Downlink Control Information, DCI);

C: Indicates whether the Resource Serving Cell ID field and the Resource BWP ID (Resource BWP ID) field exist, set 1 to exist; set 0 to not exist, and all resource identifiers (Resource ID) fields when they do not exist indicate that the resource is Belong to those indicated by the SRS Resource Set's Cell ID and SRS Resource Set's BWP ID fields;

Semi-persistent SRS resource set identifier (SP SRS Resource Set ID): corresponding to the SRS resource set identifier (SRS-ResourceSetId) in the RRC signaling;

Fi: indicates the resource type that has a spatial relationship with the SRS resource, F0 corresponds to the first SRS resource in the SRS resource set, F2 corresponds to the second, and so on. Fi is set to 1 to use the non-zero power channel state information reference signal (Non-Zero Power Channel State Information-Reference Signal, NZP-CSI-RS), set to 0 to use the synchronization signal block (Synchronization Signal Block, SSB) or SRS;

Resource ID (Resource ID): The resource ID that has a spatial relationship with the SRS resource, Resource ID0 corresponds to the first SRS resource in the SRS resource set; Resource ID1 corresponds to the second SRS resource in the SRS resource set, and so on;

Resource Serving Cell ID and Resource BWP ID: Resource ID indicates the serving cell and BWP to which the resource belongs.

It should be noted that configuring the PRS signal through RRC signaling will bring a long signaling interaction time, and the periodic reference signal may need to wait for a long time to be measured. For example, when the PRS period is 320ms, the UE needs to wait up to 320ms to receive the PRS signal once. Obviously, such a mechanism will bring a relatively long delay.

In order to reduce the time required for the positioning process, the positioning technology of release 17 (release17, Rel-17) may activate/trigger the positioning reference signal through low-level signaling, such as MAC CE or DCI, such as semi-persistent triggering through MAC CE. A periodic PRS signal or an aperiodic PRS signal is triggered by the DCI information. Correspondingly, the SRS can be triggered in a similar manner. However, at present, PRS and SRS are independently configured, and there is no guarantee that the PRS and SRS configurations can conform to a certain time domain position relationship. Some PRS signals may even be unable to be received due to the loss of DCI, or the SRS signals cannot be sent by the UE. The positioning results of Multi-RTT are affected, for example, as shown in Figure 4 below.

Based on the above problems, this application proposes a scheme for jointly indicating uplink and downlink positioning reference signal resources. The PRS resources and the SRS resources used for positioning are simultaneously triggered or activated or deactivated in the physical layer signaling, avoiding separate triggering, activation or deactivation. The signaling interaction and delay caused by deactivation also avoids the situation where only one signal resource is activated or triggered in the PRS resource and the SRS resource used for positioning, and the configuration is more efficient and reasonable.

The technical solutions of the present application are described in detail below through specific embodiments.

FIG. 5 is a schematic flowchart of a method 200 for wireless communication according to an embodiment of the present application. As shown in FIG. 5 , the method 200 may include at least part of the following contents:

S210: The network device sends first signaling, where the first signaling is used to instruct the terminal device to perform at least one uplink positioning reference signal resource and at least one downlink positioning reference signal resource for a first operation, where the first operation is activation , one of deactivation and triggering;

S220, the terminal device receives the first signaling.

In this embodiment of the present application, the network device triggers or activates or deactivates at least one uplink positioning reference signal resource and at least one downlink positioning reference signal resource simultaneously through a signaling, so as to better match the uplink positioning reference signal resource and downlink positioning Reference signal resources, avoid the loss of a certain signaling when triggering or activating or deactivating uplink positioning reference signal resources and downlink positioning reference signal resources separately in two signaling, and improve the effectiveness of reference signals and Multi-RTT positioning measurement. accuracy. In addition, signaling interaction and delay caused by separate triggering or activation or deactivation can be avoided, and the situation in which only one positioning reference signal resource in the uplink positioning reference signal resource and the downlink positioning reference signal resource is activated or triggered can be avoided. The configuration is more efficient and reasonable, and the positioning efficiency and measurement accuracy are improved.

In some embodiments, for example, the first signaling is used to indicate at least one uplink positioning reference signal resource and at least one downlink positioning reference signal resource that the terminal device needs to perform the first operation.

In some embodiments, the present application may be applied to the Multi-RTT positioning technology, and may also be applied to some other positioning technologies, which is not limited in the present application.

In some embodiments, the present application may be applied to licensed band. In addition, the present application can also be applied to an unlicensed spectrum (unlicensed band), that is, Multi-RTT measurement on the licensed+unlicensed band can be implemented based on the embodiments of the present application.

In some embodiments, the first signaling is lower layer signaling. For example, the first signaling may include, but is not limited to, at least one of the following:

MAC CE signaling, DCI.

It should be noted that the uplink positioning reference signal may be an SRS (SRS-Pos) used for positioning, or may be other uplink signals, which are not limited in this embodiment of the present application. The downlink positioning reference signal may be a PRS or other downlink signals, which is not limited in this embodiment of the present application.

In some embodiments, the at least one uplink positioning reference signal resource may be periodic, semi-static, or aperiodic. The at least one downlink positioning reference signal resource may also be periodic, semi-static, or aperiodic.

For example, MAC CE signaling is used to activate/deactivate semi-static positioning reference signal resources; DCI is used to trigger aperiodic positioning reference signal resources.

In some embodiments, multiple groups of uplink and downlink positioning reference signal resources may be configured for the terminal device through high-layer signaling (such as RRC), and then one or more groups are selected from the configured positioning reference signal resources through the first signaling. Do activation/deactivation/triggering.

It should be noted that when indicating which resource is activated/deactivated/triggered, it can be represented by a resource set ID (resource set ID), or it can be represented by aperiodic SRS resource trigger (aperiodicSRS-ResourceTrigger) adopted by aperiodic SRS or other newly introduced parameters to represent the corresponding PRS/SRS resource set, etc., which is not limited in this application.

In some embodiments, the first signaling includes a first field and a second field that are independent of each other, wherein the first field is used to indicate the at least one uplink positioning reference signal resource, and the second field is used to indicate the at least one uplink positioning reference signal resource. A downlink positioning reference signal resource. The uplink positioning reference signal resources and the downlink positioning reference signal resources are separately indicated by different fields, and the combination is relatively more flexible.

As an example 1a, the network side configures multiple sets of semi-persistent (SP) PRS resources (sets) for the terminal device through high-layer signaling: PRS resource set #1, PRS resource set #2, ..., PRS resource set #Np, and multiple sets of semi-persistent SRS resources (sets): SRS resource set #1, SRS resource set #2, ..., SRS resource set #Ns, these PRS resource (set) and SRS resource (set) are independent configured. In example 1a, when the positioning reference signal is activated/deactivated through MAC CE signaling, the activation/deactivation of one/multiple groups of PRS resources and one/multiple groups of SRS resources (which can be indicated according to the resource set identifier) will be indicated at the same time. corresponding resources), the terminal device will measure the PRS signal at the corresponding time-frequency position according to the activated PRS configuration information, and will also send the SRS signal at the corresponding time-frequency position according to the SRS configuration information.

FIG. 6 is an optional implementation of the MAC CE signaling in Example 1a, and the activated/deactivated SP PRS ID and Resource set ID can also be placed in the SRS activation/deactivation signaling. It should be noted that some parameters in Fig. 6 can refer to the above description about Fig. 3, in addition, Fig. 6 is for reference only, the number of bits required for the specific SP PRS ID and resource set ID, and whether it needs to include other PRS-related Configuration information is subject to change.

As an example 1b, the network side configures the terminal equipment with multiple sets of PRS resource sets of aperiodic types: PRS resource set #1, PRS resource set #2, . . . , PRS resource set #Np, and multiple sets of aperiodic types of SRS resource set: SRS resource set #1, SRS resource set #2, ..., SRS resource set #Ns, these PRS resource sets and SRS resource sets are independently configured. In example 1b, when the DCI triggers the positioning reference signal, one group/multiple groups of PRS resources and one/multiple groups of SRS resources are simultaneously indicated to be triggered. As in Example 1a, the terminal device performs DL-PRS measurements according to the indicated PRS resources, and transmits UL-SRS signals according to the indicated SRS resources.

For example, the DCI in Example 1b will include a 2-bit SRS request field (used to indicate the triggered aperiodic SRS signal) and an X-bit PRS request field, which may represent the resources of the triggered aperiodic PRS signal Set identifier (ID) (then the length of this field is X=ceil[log ₂ (Np)]), or it indicates that the aperiodic PRS resource trigger (aperiodicPRS-ResourceTrigger) in the high-level signaling is one of the values represented by X or Multiple PRS resource sets (then the length of this field X=ceil[log ₂ (Nap_prs_trigger)] or X=ceil[log ₂ (Nap_prs_trigger+1)], where Nap_prs_trigger is the number of values of aperiodicPRS-ResourceTrigger of aperiodic PRS ).

In some embodiments, the first signaling includes a third field, and the third field is used to indicate the at least one uplink positioning reference signal resource, and the at least one downlink positioning reference signal resource is a first association relationship with the at least one The downlink positioning reference signal resource corresponding to the uplink positioning reference signal resource. Only one field is needed to indicate uplink positioning reference signal resources, which reduces the number of bits required for signaling.

That is, if one uplink positioning reference signal resource performs the first operation, the downlink positioning reference signal resource corresponding to it in the first association relationship also performs the first operation.

Specifically, the terminal device may determine the at least one uplink positioning reference signal resource based on the third field, and determine the at least one downlink positioning reference signal resource associated with the at least one uplink positioning reference signal resource based on the first association relationship.

In some embodiments, the first association relationship may be an association relationship between uplink positioning reference signal resources and downlink positioning reference signal resources, or the first association relationship may at least include uplink positioning reference signal resources and downlink positioning reference signal resources relationship between resources.

In some embodiments, the first association relationship is pre-configured or agreed in a protocol, or the first association relationship is configured by a network device.

It should be noted that, in the first association relationship, the association relationship between uplink positioning reference signal resources and downlink positioning reference signal resources may be one-to-one, one-to-many, many-to-one, or many-to-many, This embodiment of the present application does not limit this.

In some embodiments, the first signaling includes a fourth field, where the fourth field is used to indicate the at least one downlink positioning reference signal resource, and the at least one uplink positioning reference signal resource is the first association relationship with the at least one The uplink positioning reference signal resources corresponding to the downlink positioning reference signal resources. Only one field is needed to indicate uplink positioning reference signal resources, which reduces the number of bits required for signaling.

That is, if one downlink positioning reference signal resource performs the first operation, the corresponding uplink positioning reference signal resource in the first association relationship also performs the first operation.

Specifically, the terminal device may determine the at least one downlink positioning reference signal resource based on the fourth field, and determine the at least one uplink positioning reference signal resource associated with the at least one downlink positioning reference signal resource based on the first association relationship.

As example 2a, the network side configures multiple sets of semi-persistent PRS resource sets for the terminal device through high-layer signaling: PRS resource set #1, PRS resource set #2, ..., PRS resource set #Np, and multiple sets of semi-persistent PRS resource sets SRS resource set: SRS resource set #1, SRS resource set #2, ..., SRS resource set #Ns. In addition, the high-level signaling also configures certain association relationships (which may be one-to-one, one-to-many, and many-to-one) for these PRS resource sets and SRS resource sets, as shown in FIG. 7 . When one or more groups of PRS resource sets are activated/deactivated by using MAC CE signaling, then the SRS resource sets associated with the PRS resource sets will also be activated/deactivated accordingly. For example, if the MAC CE signaling indicates PRS resource set #1, the associated SRS resource set #1 and SRS resource set #2 will also be activated/deactivated correspondingly.

As example 2b, the network side configures multiple sets of semi-persistent PRS resource sets for the terminal device through high-layer signaling: PRS resource set #1, PRS resource set #2, , PRS resource set #Np, and multiple sets of semi-persistent PRS resource sets SRS resource set: SRS resource set #1, SRS resource set #2, ..., SRS resource set #Ns.

When using MAC CE signaling to indicate one or more groups of SRS resource sets that are activated/deactivated, the PRS resource sets associated with the indicated SRS resource sets will also be activated/deactivated accordingly. For example, if the MAC CE signaling indicates the activation/deactivation of SRS resource set #3, the associated PRS resource set #2 and PRS resource set #3 will also be activated/deactivated accordingly.

In some embodiments, the first signaling includes a fifth field, where the fifth field is used to indicate the at least one uplink positioning reference signal resource and the at least one downlink positioning reference signal resource.

Of course, the resource group number may also be configured independently of the first association relationship, that is, after the first association relationship is configured, the resource group number may be configured according to the first association relationship.

As example 2c, the network side configures multiple sets of semi-persistent PRS resource sets for the terminal device through high-layer signaling: PRS resource set #1, PRS resource set #2, ..., PRS resource set #Np, and multiple sets of semi-persistent PRS resource sets SRS resource set: SRS resource set #1, SRS resource set #2, ..., SRS resource set #Ns. In addition, the high-level signaling also configures certain association relationships (which may be one-to-one, one-to-many, and many-to-one) for these PRS resource sets and SRS resource sets. MAC CE signaling can be used to indicate one or more groups of PRS+SRS resource set combinations, wherein each group of PRS+SRS resource set combinations is a pair of associated PRS resource sets and SRS resource sets, and the PRS+SRS resource set is combined in the upper layer. configured in signaling. For example, higher layer signaling can configure that PRS resource set #1 and SRS resource set #1 are associated to become resource set combination #1; PRS resource set #1 and SRS resource set #2 are associated to become resource set combination #2. The MAC CE signaling can indicate the combination number to determine the combination of PRS and SRS resource sets that are activated/deactivated at the same time. For example, MCA-CE indicates that combination 2 means that PRS resource set #1 and SRS resource set #2 are activated/deactivated at the same time.
