It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.

It is to be understood that location is one of the indispensable applications in life today, while the requirements on delay and accuracy of positioning are also getting more and more stringent. In many positioning applications, precise positioning is typically achieved through a combination of technologies, such as 1) providing location information in outdoor scenes based on the Global Navigation Satellite System (GNSS); 2) Radio technologies (e.g., LTE networks, providing a variety of options to locate users, wireless networks, terrestrial beacon systems, etc.); 3) Inertial Measurement Units (IMUs) or sensors (e.g., accelerometer based tracking of user position, gyroscopes, magnetometers, or vertical positioning with barometric pressure sensors). These techniques are expected to play an important role in achieving accurate user positioning in the future.

Enhanced positioning capabilities of The third Generation Partnership project (The 3rd Generation Partnership project,3 gpp) NR bring additional gains. The operation of the low and high frequency bands (i.e., FR1 and FR 2) and the use of a large number of antenna arrays provides an additional degree of freedom, greatly improving the positioning accuracy. Based on positioning technologies such as an Arrival Time Difference positioning method (OTDOA) and an Uplink Time Difference of Arrival (UTDOA), a Cell identifier (Cell-ID), or an enhanced Cell identifier (E-Cell-ID), time measurement using a large bandwidth (low frequency band and high frequency band) brings better performance for user positioning. With large-scale antenna systems, such as large-scale (massive) Multiple-Input Multiple-Output (massive MIMO) systems, more accurate user location is achieved by combining time measurements and the spatial and angular domains of the propagation channel.

A Sounding Reference Signal (SRS) is one of the main reference signals used for positioning, and based on the SRS transmitted by the terminal device, the network device may measure the time of arrival, the signal strength, the angle of arrival, and the like, so as to determine the location information of the terminal device.

The activation and deactivation of the SRS may be implemented based on Media Access Control Element (MAC CE) signaling, which is used to activate/deactivate the SRS for positioning (positioning) and its corresponding spatial relationship (spatial relationship).

Specifically, MAC CE (SP Positioning SRS Activation/Deactivation MAC CE) signaling for activating/deactivating SP SRS for Positioning may be as shown in fig. 2.

The MAC CE signaling in fig. 2 may specifically include the following information fields:

A/D, a cell identifier of an SRS resource set for positioning, a bandwidth Part (BWP) identifier of the SRS resource set for positioning, C, a Supplementary Uplink (SUL), an SRS resource set identifier for positioning, a spatial relationship of a resource identifier i, S, R.

A/D information field: the A/D information field indicates activation or deactivation of SP SRS resource sets for positioning. The A/D information domain occupies 1 bit, and indicates to activate an SP SRS resource set for positioning under the condition that the value of the A/D information domain is 1; and under the condition that the value of the A/D information field is 0, indicating to deactivate the SP SRS resource set for positioning.

Cell identity information field for localized SRS resource set: the information field indicates an identity of a serving cell including an activated or deactivated set of SP SRS resources for positioning. Wherein, if the C information field is set to 0, the cell id information field of the SP SRS resource set for positioning further indicates an id of a serving cell, and the serving cell contains all resources (if any) indicated by the spatial relationship information field of the resource id i. The cell identification information field of the SRS resource set for positioning occupies 5 bits.

BWP identification information field for localized SRS resource set: the Information field indicates the uplink BWP as a symbol of a designated Downlink Control Information (DCI) bandwidth part indicator, and the Information field contains activated/deactivated SP SRS resource sets for positioning. If the C information field is set to 0, the BWP identification information field of the SP SRS resource set for positioning is further used to indicate the identification of BWP, where the BWP contains all resources (if any) indicated by the spatial relationship information field of the resource identification i. The BWP identification information field of the SRS resource set for positioning occupies 2 bits.

C information field: the information field indicates whether there are 8 bits containing a cell identification information field of an SP SRS resource set for positioning and a BWP identification information field of the SP SRS resource set for positioning, except for having a spatial relationship between a resource identification i and a downlink Positioning Reference Signal (PRS), or except for having a spatial relationship between the resource identification i and an SSB. When the a/D information field is set to 1, if the C information field is set to 1, the spatial relationship of the resource identifier i includes 8 bits of the cell identifier information field of the SP SRS resource set for positioning and the BWP identifier information field of the SP SRS resource set for positioning, otherwise, if the C information field is set to 0, the spatial relationship does not exist. When the a/D information field is set to 0, the C information field is always set to 0, indicating that they do not exist.

SUL information field: the information field indicates whether the MAC CE is applied to a Normal Uplink (NUL) carrier or a SUL carrier configuration. The SUL information field is set to 1 to indicate that the MAC CE is suitable for SUL carrier configuration, and the SUL information field is set to 0 to indicate that the MAC CE is suitable for NUL carrier configuration.

SRS resource set identification information field for positioning: the information field indicates a set of SP SRS resources identified by the set of SRS resources to be activated or deactivated for positioning. The SP SRS resource set identification information field for positioning takes 4 bits.

Spatial relationship information field of resource identifier i: the spatial relationship information field of the resource identifier i exists only when the MAC CE is used for activation, i.e., the a/D information field is set to 1.M is the total number of positioning SRS resources configured under the SP SRS resource set for positioning indicated by the SP SRS resource set identification for positioning. The resource identifier i has 4 spatial relationships, and is specifically represented by F (F0 and F1) information fields. Fig. 3 to 6 show 4 spatial relationships of the resource identifier i, respectively.

S information field: the information field indicates whether a spatial relationship information field of a resource identifier i of a positioning SRS resource i in an SP SRS resource set for positioning exists. If the S information domain is set to be 1, the spatial relationship information domain of the resource identifier i exists; otherwise, the spatial relationship information field of the resource identifier i does not exist.

R information field: reserved bit, set to 0.

Specifically, fig. 3 shows a spatial relationship of a Non-Zero Power Channel State Information-Reference Signal (NZP-CSI-RS) type of the resource identifier i, fig. 4 shows a spatial relationship of an SSB type of the resource identifier i (i.e., spatial relationship Information of the SSB type described in the embodiment of the present application), fig. 5 shows a spatial relationship of an SRS type of the resource identifier i, and fig. 6 shows a spatial relationship of a downlink PRS type of the resource identifier i.

It should be noted that the spatial relationships shown in fig. 3 to fig. 6 may specifically include the following information fields:

F ₀ information field: the information field indicates a resource type of spatial relationship used as an i-th positioning SRS resource in the positioning SRS resource set indicated by the SRS resource set identification for positioning. The F ₀ The information field set to 00 indicates that the NZP CSI-RS resource index is used; the F ₀ The information field set to 01 indicates that the SSB index is used; the F ₀ The information field is set to 10 to indicate that the SRS resource index is used; f is a hydrogen atom ₀ The information field set to 11 indicates that a downlink PRS (DL-PRS) index is used. The F ₀ The information field takes 2 bits.

F ₁ Information field: when F is present ₀ When the information field is set to 10, F ₁ The information field indicates that the spatial relationship of the ith positioning SRS resource in the SP SRS resource set for positioning is the SRS resource type, and the SRS resource is indicated by the SRS resource set identification for positioning. F ₁ The information field is set to 0 to indicate that the SRS resource index (SRS resource id) is used; f ₁ The information field set to 1 indicates that an SRS resource index (SRS posresourceld) for positioning is used.

NZP-CSI-RS resource identification information field: the information field contains an NZP CSI RS resource index, represents an NZP CSI-RS resource and is used for deriving a spatial relation of positioning SRS. The NZP-CSI-RS resource identification information field occupies 8 bits.

SSB index information field: the information field contains the SSB index. The SRS index information field takes 6 bits.

PCI information field: the information field contains the physical cell identity (physcellld). The PCI field takes up 10 bits.

SRS resource identification information field: when the F1 information field is set to 0, the SRS resource identification information field indicates an index of an SRS resource (resource id); when F is present ₁ When the information field is set to 1, the SRS resource identification information field indicates an index of an SRS resource (SRS posresourceld) used for positioning. The SRS resource identification information field takes 5 bits.

DL-PRS resource set identification information field: the information field contains an index of the set of DL-PRS resources. The DL-PRS resource set identification information field takes 3 bits.

DL-PRS resource identification information field: the information field contains an index of the DL-PRS resource number. The DL-PRS resource identification information field takes 6 bits.

PI information field: the information field indicates whether a DL-PRS identity information field exists in a spatial relationship with a resource identity i of a DL-PRS. If the PI information field is set to 1, 8 bits containing a DL-PRS identification information field exist; otherwise, 8 bits will be omitted.

SI information field: the information field indicates whether the SSB index information field exists in a spatial relationship with the resource identification i of the SSB. If the SI information field is set to 1, there are 8 bits containing the SSB index information field; otherwise, 8 bits are ignored.

Resource serving cell identity i information field: the information field indicates an identity of a serving cell where the resource for spatial relationship derivation of the ith positioning SRS resource is located. The resource serving cell identity i information field takes 5 bits.

Resource BWP identifies i information field: the information field indicates UL BWP as a symbol of DCI bandwidth section indicator field, and the resource used for spatial relationship derivation of the ith positioning SRS resource is located on the resource BWP identification i information field. The resource BWP identification i information field takes 2 bits.

It should be noted that the SSB includes the SSB of the serving Cell and the SSB of the neighboring Cell, but the two SSBs are not distinguished in the spatial relationship in the MAC CE signaling for activating or deactivating the SP SRS for positioning, that is, the SSB of the serving Cell and the SSB of the neighboring Cell need to carry Physical Cell Identifier (PCI) information, which greatly increases the overhead of the MAC CE signaling.

Based on the above problems, the present application provides a scheme for optimizing a spatial relationship in MAC CE signaling for activating or deactivating SP SRS for positioning, which can save the overhead of MAC CE signaling.

The technical solution of the present application is described in detail by specific examples below.

Fig. 7 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, and as shown in fig. 7, the method 200 may include at least some of the following:

s210, a network device sends first information to a terminal device, where the first information is used to activate or deactivate a semi-static SRS for positioning, and the first information includes SSB-type spatial relationship information, and the SSB-type spatial relationship information includes indication information, where the indication information is used to indicate whether an SSB in the SSB-type spatial relationship information belongs to a serving cell, or the indication information is used to indicate whether the SSB-type spatial relationship information includes a PCI information domain;

s220, the terminal device receives the first information sent by the network device.

It should be noted that the SSB type spatial relationship information includes SSBs that may be SSBs of the serving cell or SSBs of neighboring cells. When the SSB included in the SSB-type spatial relationship information is the SSB of the serving cell, since the terminal device knows the PCI of the current serving cell, it is not necessary to indicate the PCI of the serving cell again, that is, the SSB-type spatial relationship information may not include a PCI information field, thereby saving signaling overhead.

Alternatively, in a case that the indication information is used to indicate whether the SSB in the spatial relationship information of the SSB type belongs to the serving cell, another expression of the indication information may be: the indication information is used to indicate that the SSB in the SSB type spatial relationship information belongs to the serving cell, or the indication information is used to indicate that the SSB in the SSB type spatial relationship information belongs to the neighboring cell.

Optionally, in this embodiment of the present application, the first information is MAC CE signaling. Of course, the first information may also be some other signaling, which is not limited in this application.

It should be noted that the first information may also include some other types of spatial relationship information, such as the spatial relationship information shown in fig. 3, fig. 5, and fig. 6, which is not limited in this application.

Optionally, in this embodiment of the application, in a case that the indication information is used to indicate that an SSB in the SSB-type spatial relationship information belongs to a serving cell, the PCI information field is not included in the SSB-type spatial relationship information. That is, in the case that the indication information is used to indicate that the SSB in the SSB-type spatial relationship information belongs to the serving cell, the signaling overhead of the first information (e.g., MAC CE signaling) can be saved.

That is, in the case that the indication information is used to indicate that the SSB in the SSB-type spatial relationship information belongs to the neighboring cell, the PCI information field is included in the SSB-type spatial relationship information. Further, the terminal device may determine which neighbor cell the SSB belongs to in the SSB type spatial relationship information according to the PCI.

Optionally, in this embodiment of the present application, in a case that the indication information is used to indicate that the SSB in the spatial relationship information of the SSB type belongs to the serving cell, the terminal device may ignore a PCI information field in the spatial relationship information of the SSB type. Thus, the overhead of reading/receiving the PCI information field in the SSB-type spatial relationship information can be saved, while reducing the delay.

Optionally, in this embodiment of the application, in a case that the indication information is used to indicate that the PCI information field is not included in the spatial relationship information of the SSB type, an SSB in the spatial relationship information of the SSB type belongs to the serving cell.

That is, in the case that the indication information is used to indicate that the PCI information field is included in the SSB-type spatial relationship information, the SSB in the SSB-type spatial relationship information belongs to the neighboring cell.

Optionally, in some embodiments, the indication information includes a target information field in the SSB type spatial relationship information. Or, the indication information is a target information field in the SSB type spatial relationship information.

That is, the target information field is used to indicate whether the SSB in the SSB-type spatial relationship information belongs to the serving cell, or the target information field is used to indicate whether the PCI information field is included in the SSB-type spatial relationship information.

Example 1, the target information field is also used to indicate the type of spatial relationship information, i.e. the target information field may also implement the function of the F0 information field in fig. 4 described above. In particular, the target information field may occupy 3 bits.

When the target information field is configured to be 000, the spatial relationship information of the NZP CSI-RS type may be indicated;

when the target information field is configured to 001, it may indicate that the SSB in the SSB-type spatial relationship information belongs to a neighboring cell, or may indicate that the SSB-type spatial relationship information includes a PCI information field;

when the target information field is configured to be 010, the spatial relationship information of the SRS type can be indicated;

when the target information field is configured to be 011, spatial relationship information of a DL-PRS type can be indicated;

when the target information field is configured to be 100, it may indicate that the SSB in the SSB-type spatial relationship information belongs to the serving cell, or it may indicate that the PCI information field is not included in the SSB-type spatial relationship information.

E.g. in the target information field (F) ₀ Representation) is configured as 100, the spatial relationship information of the SSB type may be as shown in fig. 8.

Also for example, in the target information field (F) ₀ Representing) is configured to 001, the spatial relationship information of the SSB type may be as shown in fig. 9.

In fig. 8 and 9, F is removed ₀ For the information fields other than the information field and the PCI information field, reference may be made to the above description related to fig. 4, which is not described herein again.

Example 2, the target information field is also used to indicate whether to carry an SSB index. I.e. the target information field may also implement the functionality of the SI information field in fig. 4 described above. Specifically, the target information field may occupy 2 bits.

When the target information field is configured to 00, it may indicate that the SSB index is carried and the SSB belongs to the serving cell, or it may indicate that the SSB index is carried and the SSB type spatial relationship information does not include the PCI information field;

when the target information field is configured to be 01, it may indicate that the SSB index is not carried and the SSB belongs to the serving cell, or it may indicate that the SSB index is not carried and the spatial relationship information of the SSB type does not include the PCI information field;

when the target information field is configured to be 10, it may be indicated that the SSB index is carried and the SSB belongs to the neighboring cell, or it may be indicated that the spatial relationship information carrying the SSB index and the SSB type includes a PCI information field;

when the target information field is configured to be 11, it may be indicated that the SSB index is not carried and the SSB belongs to the neighboring cell, or it may be indicated that the PCI information field is included in the spatial relationship information of the SSB type and the SSB index is not carried.

For example, when the target information field (SI expression) is configured to 00, the SSB type spatial relationship information may be as shown in fig. 10.

For another example, when the target information field (SI expression) is configured to be 10, the SSB type spatial relationship information may be as shown in fig. 11.

It should be noted that, in fig. 10 and fig. 11, reference may be made to the above description related to fig. 4 for information fields other than the SI information field and the PCI information field, which is not described herein again.

Example 3, the destination information field is a reservation information field. I.e. the target information field may also be an R information field as described above in fig. 4. Specifically, the target information field may occupy 1 bit.

When the target information field is configured to be 0, it may indicate that the SSB in the SSB-type spatial relationship information belongs to a neighboring cell, or may indicate that the SSB-type spatial relationship information includes a PCI information field;

when the target information field is configured to be 1, it may indicate that the SSB in the SSB-type spatial relationship information belongs to the serving cell, or it may indicate that the PCI information field is not included in the SSB-type spatial relationship information.

For example, when the target information field (denoted by N) is configured to be 1, the SSB type spatial relationship information may be as shown in fig. 12.

For another example, when the target information field (denoted by N) is configured as 0, the SSB-type spatial relationship information may be as shown in fig. 13.

That is, the target information field may be a newly added dedicated information field. Alternatively, in this case, the target information field occupies 1 bit. Of course, the target information field may occupy more bits, such as 2 bits, which is not limited in this application.

Example 5, the target information field is an information field indicating whether a PCI information field is included. That is, the target information field may be a newly added dedicated information field. Alternatively, in this case, the target information field occupies 1 bit. Of course, the target information field may occupy more bits, such as 2 bits, which is not limited in this application.
