Such devices include glasses, gloves, watches, clothing, shoes, etc. A wearable device is a portable device that can be directly worn on the body or integrated into the user's clothes or accessories. A wearable device is not just a hardware device, but also realizes powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable intelligent devices include those with complete functions and large sizes that can achieve complete or partial functions without relying on a smart phone, such as smart watches or smart glasses, etc., and those that only focus on a certain type of application function and need to cooperate with other devices such as smart phones, such as various smart bracelets and smart jewelry for physical sign monitoring.

[0051] Exemplarily, the communication system 100 applied in the embodiments of the present application is as Figure 1 shown. The communication system 100 may include a network device 110. The network device 110 may be a device that communicates with a terminal device 120 (or referred to as a communication terminal, terminal). The network device 110 may provide communication coverage for a specific geographical area and may communicate with terminal devices located within the coverage area.

[0052] Figure 1 Exemplarily, one network device and two terminal devices are shown. Optionally, the communication system 100 may include multiple network devices and the coverage range of each network device may include other numbers of terminal devices. The embodiments of the present application do not limit this.

[0053] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity. The embodiments of the present application do not limit this.

[0054] It should be understood that in the embodiments of the present application, a device with communication functions in the network / system may be referred to as a communication device. Figure 1Taking the illustrated communication system 100 as an example, the communication devices may include a network device 110 and a terminal device 120 having communication functions. The network device 110 and the terminal device 120 may be the specific devices described above, which will not be elaborated here; the communication devices may also include other devices in the communication system 100, such as other network entities like network controllers and mobility management entities, which are not limited in the embodiments of this application.

[0055] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally represents an "or" relationship between the associated objects before and after.

[0056] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or a representation of an association relationship. For example, A indicates B, which can mean that A directly indicates B. For example, B can be obtained through A; it can also mean that A indirectly indicates B. For example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0057] In the description of the embodiments of this application, the term "corresponding" can represent a direct or indirect corresponding relationship between two parties, can also represent an association relationship between two parties, or can be relationships such as indication and being indicated, configuration and being configured.

[0058] It should be understood that location is one of the indispensable applications in current life, and at the same time, the requirements for the latency and accuracy of positioning are becoming increasingly strict. In many positioning applications, precise positioning is usually achieved through a combination of multiple technologies. For example, 1) providing location information in outdoor scenarios based on the Global Navigation Satellite System (GNSS); 2) radio technologies (such as LTE networks, providing multiple options for positioning users, wireless networks, ground beacon systems, etc.); 3) Inertial Measurement Units (IMUs) or sensors (such as tracking the user's location based on accelerometers, gyroscopes, magnetometers, or using atmospheric pressure sensors for vertical positioning). These technologies are expected to play an important role in achieving accurate user positioning in the future.

[0059] The enhanced positioning capabilities of the 3GPP New Radio (NR) bring additional gains. The operation in low and high frequency bands (i.e., FR1 and FR2) and the use of large antenna arrays provide additional degrees of freedom, greatly improving positioning accuracy. Positioning technologies such as Observed Time Difference of Arrival (OTDOA), Uplink Time Difference of Arrival (UTDOA), Cell-ID, or Enhanced Cell-ID (E-Cell-ID) use the large bandwidth (both low and high frequency bands) for time measurement, which brings better performance for user positioning. By using large-scale antenna systems such as massive Multiple-Input Multiple-Output (massive MIMO) systems, more accurate user positions can be achieved by combining time measurement with the spatial and angular domains of the propagation channel.

[0060] The Sounding Reference Signal (SRS) is one of the main reference signals used for positioning. Based on the SRS sent by the terminal device, the network device can measure the time of arrival, signal strength, angle of arrival, etc., so as to determine the location information of the terminal device.

[0061] The activation and deactivation of the SRS can be achieved based on Media Access Control Control Element (MAC CE) signaling, which is used to activate / deactivate the SRS for positioning and its corresponding spatial relation.

[0062] Specifically, the MAC CE (SP Positioning SRS Activation / Deactivation MAC CE) signaling for activating / deactivating the SP SRS for positioning can be as Figure 2 shown.

[0063] Figure 2 The MAC CE signaling in

[0064] A / D, cell identifier of the SRS resource set for positioning, BandWidth Part (BWP) identifier of the SRS resource set for positioning, C, Supplementary Uplink (SUL), SRS resource set identifier for positioning, spatial relationship of resource identifier i, S, R.

[0065] A / D information field: This A / D information field indicates the activation or deactivation of the SP SRS resource set for positioning. Among them, the A / D information field occupies 1 bit. When the value of the A / D information field is 1, it indicates the activation of the SP SRS resource set for positioning; when the value of the A / D information field is 0, it indicates the deactivation of the SP SRS resource set for positioning.

[0066] Cell identifier information field of the SRS resource set for positioning: This information field indicates the identifier of the serving cell, and the serving cell includes the activated or deactivated SP SRS resource set for positioning. Among them, if the C information field is set to 0, the cell identifier information field of the SP SRS resource set for positioning also indicates the identifier of the serving cell, and the serving cell contains all resources (if any) indicated by the spatial relationship information field of resource identifier i. The cell identifier information field of the SRS resource set for positioning occupies 5 bits.

[0067] BWP identifier information field of the SRS resource set for positioning: This information field indicates the symbol of the uplink BWP as the specified Downlink Control Information (DCI) bandwidth part indicator, and this information field contains the activated / deactivated SP SRS resource set for positioning.

When the A / D information field is set to 1, if this C information field is set to 1, then the spatial relationship of the resource identity i includes the 8 bits of the cell identity information field for the SP SRS resource set used for positioning and the BWP identity information field for the SP SRS resource set used for positioning; otherwise, if this C information field is set to 0, they do not exist. When the A / D information field is set to 0, this C information field is always set to 0, indicating that they do not exist.

[0069] SUL information field: This information field indicates whether the MAC CE is applied to the Normal Uplink (NUL) carrier or the SUL carrier configuration. Setting this SUL information field to 1 indicates that the MAC CE is applicable to the SUL carrier configuration, and setting this SUL information field to 0 indicates that the MAC CE is applicable to the NUL carrier configuration.

[0070] SRS resource set identity information field for positioning: This information field indicates the SP SRS resource set for positioning to be activated or deactivated identified by the SRS resource set. The SP SRS resource set identity information field for positioning occupies 4 bits.

[0071] Spatial relationship information field of resource identity i: The spatial relationship information field of resource identity i only exists when the MAC CE is used for activation, that is, when the A / D information field is set to 1. M is the total number of positioning SRS resources configured under the SPSRS resource set for positioning represented by the SRS resource set identity for positioning. There are 4 spatial relationships for resource identity i, specifically represented by the F (F0 and F1) information fields. Figures 3 to 6 Four spatial relationships of resource identity i are shown respectively.

[0072] S information field: This information field indicates whether the spatial relationship information field of the resource identity i of the positioning SRS resource i in the SP SRS resource set used for positioning exists. If the S information field is set to 1, then the spatial relationship information field of the resource identity i exists; otherwise, the spatial relationship information field of the resource identity i will not exist.

[0073] R information field: Reserved bit, set to 0.

[0074] Specifically, Figure 3Shows the spatial relationship of the Non-Zero Power Channel State Information-Reference Signal (NZP-CSI-RS) type of resource identifier i, Figure 4 Shows the spatial relationship of the SSB type of resource identifier i (i.e., the spatial relationship information of the SSB type described in the embodiments of the present application), Figure 5 Shows the spatial relationship of the SRS type of resource identifier i, Figure 6 Shows the spatial relationship of the downlink PRS type of resource identifier i.

[0075] It should be noted that the above Figures 3 to 6 The spatial relationships shown may specifically include the following information fields:

[0076] F0 information field: This information field indicates the resource type of the spatial relationship of the i-th positioning SRS resource in the positioning SRS resource set represented by the SRS resource set identifier for positioning. When the F0 information field is set to 00, it indicates the use of the NZP CSI-RS resource index; when the F0 information field is set to 01, it indicates the use of the SSB index; when the F0 information field is set to 10, it indicates the use of the SRS resource index; when the F0 information field is set to 11, it indicates the use of the downlink PRS (DL-PRS) index. The F0 information field occupies 2 bits.

[0077] F1 information field: When the F0 information field is set to 10, the F1 information field indicates that the spatial relationship of the i-th positioning SRS resource in the SP SRS resource set for positioning is of the SRS resource type, and the SRS resource is indicated by the SRS resource set identifier for positioning. The F1 information field is set to 0 to indicate the use of the SRS resource index (SRS ResourceId); the F1 information field is set to 1 to indicate the use of the SRS resource index for positioning (SRS PosResourceId).

[0079] SSB index information field: This information field contains the SSB index. The SRS index information field occupies 6 bits.

[0080] PCI information field: This information field contains the Physical Cell Identifier (PhysCellId). The PCI information field occupies 10 bits.

[0081] SRS Resource Identification Information Field: When the F1 information field is set to 0, this SRS resource identification information field indicates the index of the SRS resource (ResourceId); when the F1 information field is set to 1, this SRS resource identification information field indicates the index of the SRS resource (SRS PosResourceId) used for positioning. This SRS resource identification information field occupies 5 bits.

[0082] DL-PRS Resource Set Identification Information Field: This information field contains the index of the DL-PRS resource set. This DL-PRS resource set identification information field occupies 3 bits.

[0083] DL-PRS Resource Identification Information Field: This information field contains the index of the DL-PRS resource number. This DL-PRS resource identification information field occupies 6 bits.

[0085] PI Information Field: This information field indicates whether the DL-PRS identification information field exists in the spatial relationship of the resource identifier i with DL-PRS. If the PI information field is set to 1, there are 8 bits containing the DL-PRS identification information field; otherwise, the 8 bits will be omitted.

[0086] SI Information Field: This information field indicates whether the SSB index information field exists in the spatial relationship of the resource identifier i with SSB. If the SI information field is set to 1, there are 8 bits containing the SSB index information field; otherwise, the 8 bits are ignored.

[0087] Resource Serving Cell Identification i Information Field: This information field indicates the identification of the serving cell where the resource for the spatial relationship derivation of the i-th positioning SRS resource is located. This resource serving cell identification i information field occupies 5 bits.

[0088] Resource BWP Identification i Information Field: This information field indicates the symbol of the UL BWP as the DCI bandwidth part indicator field, and the resource for the spatial relationship derivation of the i-th positioning SRS resource is located on this resource BWP identification i information field. This resource BWP identification i information field occupies 2 bits.

[0089] It should be noted that the SSB includes the SSB of the serving cell and the SSB of the neighboring cell, but there is no distinction between these two types of SSBs in the spatial relationship of the MAC CE signaling used to activate or deactivate the SP SRS for positioning. That is to say, both the SSB of the serving cell and the SSB of the neighboring cell need to carry the Physical Cell Identifier (PCI) information, which greatly increases the overhead of the MAC CE signaling.

[0090] Based on the above problems, the present application proposes a solution to optimize the spatial relationship in the MAC CE signaling for activating or deactivating the SP SRS for positioning, which can save the overhead of the MAC CE signaling.

[0091] The technical solution of the present application is described in detail below through specific embodiments.

[0092] Figure 7 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As Figure 7 shown, the method 200 may include at least some of the following:

[0093] S210, the network device sends first information to the terminal device, the first information is used to activate or deactivate the semi-static SRS for positioning, and the first information includes spatial relationship information of the SSB type, the spatial relationship information of the SSB type includes indication information, wherein the indication information is used to indicate whether the SSB in the spatial relationship information of the SSB type belongs to the serving cell, or the indication information is used to indicate whether the PCI information field is included in the spatial relationship information of the SSB type;

[0094] S220, the terminal device receives the first information sent by the network device.

[0095] It should be noted that the SSB included in the spatial relationship information of the SSB type may be the SSB of the serving cell or the SSB of a neighboring cell. When the SSB included in the spatial relationship information of the SSB type is the SSB of the serving cell, since the terminal device already knows the PCI of the current serving cell, there is no need to indicate the PCI of the serving cell again, that is, the PCI information field may not be included in the spatial relationship information of the SSB type, thereby saving signaling overhead.

[0096] Optionally, when 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 form of the indication information may be: the indication information is used to indicate that the SSB in the spatial relationship information of the SSB type belongs to the serving cell, or the indication information is used to indicate that the SSB in the spatial relationship information of the SSB type belongs to a neighboring cell.

[0097] Optionally, in the embodiment of the present application, the first information is a MAC CE signaling. Of course, the first information may also be some other signaling, and the present application does not limit this.

[0098] It should be noted that the first information may also include some other types of spatial relationship information, such as the above Figure 3 、 Figure 5 andFigure 6 The spatial relationship information shown is not limited in this application.

[0099] Optionally, in the embodiments of this application, when 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 PCI information field is not included in the spatial relationship information of the SSB type. That is, when 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 signaling overhead of the first information (such as the MAC CE signaling) can be saved.

[0100] That is, when the indication information is used to indicate that the SSB in the spatial relationship information of the SSB type belongs to a neighboring cell, the PCI information field is included in the spatial relationship information of the SSB type. Further, the terminal device can determine which neighboring cell the SSB in the spatial relationship information of the SSB type belongs to according to the PCI.

[0101] Optionally, in the embodiments of this application, when 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 can ignore the PCI information field in the spatial relationship information of the SSB type. Thus, the overhead generated by reading / receiving the PCI information field in the spatial relationship information of the SSB type can be saved, and the latency can be reduced at the same time.

[0102] Optionally, in the embodiments of this application, when the indication information is used to indicate that the PCI information field is not included in the spatial relationship information of the SSB type, the SSB in the spatial relationship information of the SSB type belongs to the serving cell.

[0103] That is, when the indication information is used to indicate that the PCI information field is included in the spatial relationship information of the SSB type, the SSB in the spatial relationship information of the SSB type belongs to a neighboring cell.

[0104] Optionally, in some embodiments, the indication information includes the target information field in the spatial relationship information of the SSB type. Or, the indication information is the target information field in the spatial relationship information of the SSB type.
