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. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In the prior art, the path loss reference signal of the SRS configured for positioning by RRC is specifically as follows:

when the path loss reference signal of the SRS for positioning needs to be updated, the network side notifies the UE through an RRC reconfiguration message, which increases RRC signaling overhead and delays relatively. A method for updating a path loss reference signal of a common SRS based on a Medium Access Control (MAC) Control unit (CE) is introduced, where the common SRS may refer to other SRS different from an SRS used for positioning. The MAC CE updates the MAC CE for the SRS Pathloss Reference signal (SRS Pathloss Reference RS Update MAC CE). Since the path loss Reference signal of the normal SRS is different from the path loss Reference signal of the SRS for positioning, the conventional SRS Pathloss Reference RS Update MAC CE cannot be directly applied to Update the path loss Reference signal of the SRS for positioning. The embodiment of the application provides a new MAC CE, which is used for configuring a path loss reference signal of an SRS for positioning. Alternatively, the embodiment of the present application extends the existing SRS Pathloss Reference RS Update MAC CE, or extends the existing MAC CE for other purposes, and is used to configure the path loss Reference signal of the SRS for positioning. The configuration may refer to that the network device initially configures the path loss reference signal for the terminal device, or may refer to that the network device updates the path loss reference signal for the terminal device after initial configuration. In the following embodiments, the foregoing modes will be described in detail with reference to the accompanying drawings.

An embodiment of the present application provides a method for configuring path loss reference information, and fig. 2 is a flowchart illustrating an implementation of the method 200 for configuring path loss reference information according to the embodiment of the present application, where the method may be optionally applied to the system shown in fig. 1, for example, but is not limited thereto, the method is applied to a terminal device in the system shown in fig. 1. The method includes at least part of the following.

S210: a first Medium Access Control (MAC) Control Element (CE) is received.

Optionally, the first MAC CE is configured to update, for the terminal device, a path loss reference signal of the SRS for positioning; alternatively, the first MAC CE may also be configured to initially configure a path loss reference signal of the SRS for positioning for the terminal device.

According to the received first MAC CE, the UE can acquire a path loss reference signal of the SRS configured for positioning by the network side.

Optionally, the first MAC CE is configured to configure, for the terminal device, a path loss reference signal used by an SRS resource set (SRS resource set) of the SRS for positioning; or, the first MAC CE is configured to configure, for the terminal device, a path loss reference signal used by an SRS resource (SRS resource) of the SRS for positioning. And thus is used to indicate a path loss reference signal (pathloss RS) to be used by the SRS resource set, or to indicate a pathloss reference RS to be used by the SRS resource.

In some embodiments, the path loss reference signal indicated by the first MAC CE includes at least one of:

a serving cell Synchronization Signal Block (SSB);

a neighbor cell SSB;

downlink (DL) Positioning Reference Signal (PRS);

channel State Information (CSI) -Reference Signal (RS);

accordingly, the first MAC CE indicates at least one of:

an identity of a serving cell SSB;

the identification of the adjacent cell SSB and cell information corresponding to the adjacent cell SSB;

an identity of the DL PRS;

identification of CSI-RS.

The serving cell SSB, the neighboring cell SSB, and the DL PRS are types of path loss reference signals of the existing SRS for positioning, and a new type of path loss reference signal of the SRS for positioning, that is, CSI-RS, may be extended in the embodiments of the present application.

When the path loss reference signals configured by the first MAC CE are of the different types, the first MAC CE correspondingly indicates identification information of the path loss reference signals of the different types; optionally, the first MAC CE may further include other related information of the path loss reference signal.

For example, in case the path loss reference signal configured by the first MAC CE includes the serving cell SSB, the first MAC CE indicates an identity of the serving cell SSB, such as an index of the serving cell SSB. The indication may refer to that the first MAC CE includes an identifier of the serving cell SSB, or may refer to that the first MAC CE includes other information capable of indirectly indicating the identifier of the serving cell SSB. In the following examples, the term "indicating" is used synonymously. Further, cell information, such as a Physical Cell Identity (PCI) corresponding to the serving Cell SSB, may also be indicated in the first MAC CE.

For another example, in a case that the path loss reference signal configured by the first MAC CE includes the neighbor cell SSB, the first MAC CE indicates the identifier of the neighbor cell SSB and cell information corresponding to the neighbor cell SSB. The identifier of the neighboring cell SSB may specifically be an index of the serving cell SSB, and the cell information corresponding to the neighboring cell SSB may specifically be a PCI.

As another example, in a case where the path loss reference signal configured by the first MAC CE includes DL PRS, the first MAC CE indicates an identity of the DL PRS, such as an index of the DL PRS. Further, the first MAC CE may also indicate configuration information to which the DL PRS belongs. Optionally, the configuration information to which the DL PRS belongs includes resource set identification of the DL PRS and/or resource identification of the DL PRS, such as an index of the resource set including the DL PRS and/or an index of the resource of the DL PRS.

As another example, in a case where the path loss reference signal configured by the first MAC CE includes CSI-RS, the first MAC CE indicates an identity of the CSI-RS.

In order to be able to configure the different types of path loss reference signals, optionally, in the embodiment of the present application, the length of the flag of the path loss reference signal in the first MAC CE is set to 8 bits (bit).

Since the first MAC CE can indicate different types of path loss reference signals, in some embodiments, the first MAC CE may include first indication information for indicating the type of the path loss reference signal updated this time.

For example, if there are three types of path loss reference signals, including serving cell SSB, neighbor cell SSB, DL PRS; then, the length of the first indication information may be 1bit (bit), and two different values of the 1bit first indication information respectively indicate that the type of the path loss reference signal is SSB or DL PRS. Further, the length of the first indication information may be 2 bits, and in the case that the type of the indication path loss reference signal is SSB, the serving cell SSB and the neighbor cell SSB are further distinguished.

Furthermore, the first MAC CE may further indicate which BandWidth Part (BWP) of which serving cell the updated pathloss reference signal is applied to, and a pathloss reference signal indicating which SRS resource set is updated; accordingly, the first MAC CE may indicate at least one of the following to indicate the above information:

an identity of a serving cell;

identification of UL BWP;

identification of SRS resource sets.

In some embodiments, the first MAC CE may be a MAC CE newly defined for SRS for positioning, or an extended SRS Pathloss Reference RS Update MAC CE. Or, the embodiment of the present application may also extend an existing MAC CE, where the MAC CE is configured to activate or deactivate an SRS for Positioning and indicate a spatial relationship corresponding to an SRS resource, such as an SP Positioning SRS Activation/Deactivation MAC CE); the MAC CE may be referred to as a second MAC CE. In the two embodiments for extending the existing MAC CE, the first MAC CE generated after the extension indicates the original information in the MAC CE before the extension in addition to the relevant information indicating the pathloss reference signal, which will be specifically described in detail in the following

embodiments

2 and 3.

Example 1:

fig. 3 is a schematic structural diagram of a first MAC CE in embodiment 1 of the present application. The first MAC CE is a new MAC CE introduced for the SRS for positioning, for configuring a path loss reference signal for the SRS for positioning.

Optionally, the first MAC CE indicates a path loss reference signal to be used by the SRS resource set; and/or a path loss reference signal to be used by the SRS resource.

As shown in fig. 3, the first MAC CE includes the following fields (fields):

serving Cell identification (Serving Cell ID) field: this field is used to indicate the identity of the serving cell. Wherein the activated SRS resource set is included. The length setting of this field may be 5 bits.

BWP identification (BWP ID) field: this field indicates an Uplink (UL) bandwidth part (BWP) as a code point of a DCI bandwidth part indicator field (DCI bandwidth part indicator field) specified in TS38.212[9 ]. Wherein the activated SRS resource set is included. The length of this field may be set to 2 bits.

SRS Resource Set identification (SRS Resource Set ID) field: this field indicates the identity of the SRS resource set, which can be the SRS-PosResourceSetId specified in TS 38.331[5 ]. The length of this field may be set to 4 bits.

A path loss Reference signal identification (Pathloss Reference RS ID) field: this field indicates the identification of the path loss reference signal, which may be the srs-pathlossfrereferenceRS-pos-Id specified in TS 38.331[5 ]. The length of this field may be set to 8 bits.

In this embodiment, the path loss reference signal indicated by the first MAC CE may include the following:

a serving cell SSB;

a neighbor cell SSB;

DL PRS；

CSI-RS。

correspondingly, the Pathloss Reference RS ID field may specifically indicate an identifier of a serving cell SSB, an identifier of a neighboring cell SSB, an identifier of a DL PRS, and an identifier of a CSI-RS.

When the path loss reference signal indicated by the first MAC CE is the serving cell SSB, optionally, the first MAC CE may also indicate cell information, such as a PCI, corresponding to the serving cell.

When the path loss reference signal indicated by the first MAC CE is the neighbor cell SSB, the first MAC CE further indicates cell information, such as PCI, corresponding to the neighbor cell.

As shown in fig. 3, in order to indicate the PCI, the first MAC CE may include a PCI field for indicating cell information corresponding to the serving cell SSB or the neighboring cell SSB; optionally, the field contains a physical cell identification, which may be PhysCellId as specified in TS 38.331[ 2 ], [5] and/or TS 37.355 ]. The length of this field may be set to 10 bits. Optionally, when the path loss reference signal indicated by the first MAC CE is the serving cell SSB, the first MAC CE may or may not include the PCI field; if the PCI field is not included, the first MAC CE does not include the 6 th byte (Oct 6) and the 7 th byte (Oct 7) shown in FIG. 3. When the path loss reference signal indicated by the first MAC CE is the neighbor cell SSB, the first MAC CE includes a PCI field for indicating a PCI corresponding to the neighbor cell.

When the path loss reference signal indicated by the first MAC CE is DL PRS, the first MAC CE may further indicate configuration information to which the DL PRS belongs, such as a Resource Set identifier (DL-PRS Resource Set ID) of the DL PRS and/or a Resource identifier (DL-PRS Resource ID) of the DL PRS.

As shown in fig. 3, a Resource Set identifier (DL-PRS Resource Set ID) field of DL PRS may be included in the first MAC CE for indicating the Resource Set identifier of DL PRS; optionally, this field contains an index of the DL-PRS resource set, which may be nr-DL-PRS-ResourceSetId specified in 37.355[23 ]. The first MAC CE may further include a Resource identifier (DL-PRS Resource ID) field of DL PRS for indicating a Resource set identifier of DL PRS; optionally, this field contains an index of the DL-PRS Resource, which may be nr-DL-PRS-Resource-Id specified in 37.355[23 ].

Further, as shown in fig. 3, the first MAC CE may include an indication information (F) field, where the indication information may be the first indication information, and is used to indicate a type of the pathloss reference signal. The length of the F field shown in fig. 3 is 1bit, and 2 different values of the 1bit can be used to indicate that the path loss reference signal is SSB or DL PRS respectively. If the length of the F field is 2 bits, it is possible to further distinguish whether the SSB is a serving cell SSB or a neighbor cell SSB. For example, when the length of the F field is 2 bits, a value of "00" or "01" indicates that the type of the path loss reference signal is DL PRS, a value of "10" indicates that the type of the path loss reference signal is serving cell SSB, and a value of "11" indicates that the type of the path loss reference signal is neighbor cell SSB. Of course, the value and the indication content of the F field are only examples, and the indication manner of the F field is not limited in this embodiment of the application. While the R field in fig. 3 is a reserved field, the embodiment of the present application may adopt any N (N is a positive integer) reserved fields as the F field for indicating the type of the pathloss reference signal.

In some embodiments, as shown in fig. 3, a Serving Cell identification (Serving Cell ID) field and a BWP identification field may be set to a first byte in the first MAC CE; a first indication information (F) field and an SRS Resource Set identification (SRS Resource Set ID) field may be Set to a second byte in the first MAC CE; a path loss Reference signal identification (RS ID) field may be set to a third byte in the first MAC CE. The subsequent field in the first MAC CE may be an optional field.

Example 2:

FIG. 4 is a schematic structural diagram of a conventional SRS Path Reference RS Update MAC CE. The existing SRS Pathloss Reference RS Update MAC CE is used to Update the path loss Reference signal of the normal SRS, which may refer to other SRS besides the SRS used for positioning.

As shown in fig. 4, the conventional SRS Pathloss Reference RS Update MAC CE has a length of 3 bytes, and includes a Serving Cell identifier (Serving Cell ID) field, a BWP identifier (BWP ID) field, an SRS Resource Set identifier (SRS Resource Set ID) field, and a Pathloss Reference signal identifier (Pathloss Reference RS ID) field. Wherein, the length of the Path Reference RS ID field is 6 bits. In order to be able to indicate different types of path loss Reference signals of the posing SRS, the present embodiment may extend the length of the path loss Reference RS ID field in the MAC CE shown in fig. 4 to 8 bits. For example, the Pathloss Reference RS ID field in the existing SRS Pathloss Reference RS Update MAC CE is extended to the entire byte where it is located.

As in embodiment 1, the path loss reference signal indicated by the first MAC CE in this embodiment may include the following:

a serving cell SSB;

Correspondingly, this embodiment may extend a Resource Set identifier (DL-PRS Resource Set ID) field of a DL PRS, a Resource identifier (DL-PRS Resource ID) field of the DL PRS, and a PCI field, and the content of each field may be the same as the content of the corresponding field in embodiment 1, which is not described herein again.

Optionally, this embodiment may use any N (N is a positive integer) reserved (R) fields in the MAC CE as the first indication information (F) field, which is used to indicate the type of the pathloss reference signal. Optionally, the indication information is the first indication information. The specific indication manner of the indication information field may be the same as that of embodiment 1, and is not described herein again.

In this embodiment, a Serving Cell identification (Serving Cell ID) field and a BWP identification field may be set to the first byte in the first MAC CE; a first indication information (F) field and an SRS Resource Set identification (SRS Resource Set ID) field may be Set to a second byte in the first MAC CE; a path loss Reference signal identification (RS ID) field may be set to a third byte in the first MAC CE.

Example 3:

in this embodiment, the present SP Positioning SRS Activation/Deactivation MAC CE is added, so that the MAC CE has the functions of activating/deactivating the SRS for Positioning and indicating the spatial relationship corresponding to the SRS resource, and meanwhile, can update the path loss reference signal of the SRS for Positioning.

Fig. 5 is a schematic structural diagram of a first MAC CE in embodiment 3 of the present application. Alternatively, as shown in fig. 5, the path loss reference signal information (Pathloss reference RS info) is an extended part of this embodiment and may be used to indicate the path loss reference signal. The part before the path reference RS info is the content contained in the existing SP Positioning SRS Activation/Deactivation MAC CE, and is used for activating/deactivating the SRS used for Positioning and indicating the spatial relationship corresponding to the SRS resource. The method specifically comprises the following steps:

activation/deactivation (a/D) field: this field is used to indicate activation or deactivation of the indicated set of SP Positioning SRS resources. The length of the field is 1bit, activation is represented when the value is 1, and deactivation is represented when the value is 0.

Cell identification (location SRS Resource Set' Cell ID) field of the Resource Set of location SRS: this field is used to indicate the serving cell, which contains the activated/deactivated set of location SRS resources. If the C field is set to 0, this field is also used to indicate the identity of the serving cell containing all the resources indicated by the Spatial relationship for Resource IDi field. The field is 5 bits in length.

BWP identity of Resource Set of Positioning SRS (Positioning SRS Resource Set's BWP ID) field: this field indicates an Uplink (UL) bandwidth part (BWP) as a code point of a DCI bandwidth part indicator field (DCI bandwidth part indicator field) specified in TS38.212[9 ]. Wherein, the activated/inactivated SP Positioning SRS resource sets are included. If the C field is set to 0, this field is also used to indicate the identity of the BWP containing all the resources indicated by the Spatial relationship for Resource IDi field. The field length is 2 bits.

C field: this field is used to indicate whether the byte contains the Resource Serving Cell ID field and whether the Resource BWP ID field in the Spatial relationship for Resource IDi field is present. When the value of the A/D field is 1, if the value of the C field is 1, the byte contains a Resource Serving Cell ID field and a Resource BWP ID field in a Spatial relationship for Resource IDi field exists; if the C field takes a value of 0, it is absent. When the value of the A/D field is 0, the value of the C field is always 1, which indicates that the field is not included.

SUL field: this field is used to indicate whether the MAC CE supports a Normal Uplink (NUL) carrier configuration or a Supplemental Uplink (SUL) carrier configuration. When the field value is 1, the SUL carrier configuration is supported; when the value of the field is 0, the field indicates that the NUL carrier configuration is supported.

Posioning SRS Resource Set identification (posioning SRS Resource Set ID) field: this field indicates the activated/inactivated SP Positioning SRS Resource Set, which may be the SRS-PosResourceSetId specified in TS 38.331[5 ]. The length of this field is 4 bits.

Spatial relationship for Resource Idi field of Resource: this field is only present when the MAC CE is used for activation (e.g., a/field D takes a value of 1). M is the number of Positioning SRS resources in the SP Positioning SRS Resource Set indicated by the Positioning SRS Resource Set ID field. Resource Idi has a 4-class spatial relationship, which 4-class spatial relationship may be indicated by F fields (F0 and F1).

And (2) S field: this field is used to indicate whether the Spatial relationship for Resource Idi field exists. If the S field takes the value of 1, the Spatial relationship for Resource Idi field exists, otherwise, the Spatial relationship for Resource Idi field does not exist.

Reserved (R) field R: this field takes the value 0.

The above are the fields in the conventional SP Positioning SRS Activation/Deactivation MAC CE. In this embodiment, the existing SP Positioning SRS Activation/Deactivation MAC CE is extended to the first MAC CE, which includes the above fields. Optionally, the first MAC CE comprises at least one of:

a second information indication field for indicating second indication information for activating or deactivating a resource set of the SRS for positioning; such as the a/D field described above.

A spatial relationship field for indicating spatial relationship information corresponding to resources in a resource set of the SRS for positioning; such as the Positoining SRS Resource Set ID field described above.

A third indication information field for indicating whether the spatial relationship information is contained; such as the S field described above.
