Fig. 1 is a schematic flowchart of a semi-persistently scheduled reactivation determination method according to an embodiment of the present disclosure. The semi-persistently scheduled reactivation determination method shown in this embodiment can be executed by a terminal, and the terminal includes but is not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with network-side equipment, and the network-side equipment includes but is not limited to network-side equipment in communication systems such as 4G, 5G, and 6G, such as base stations and core networks.

In one embodiment, the network side device can configure one or more sets of SPS configurations for the terminal, and when it needs to use one of the SPSs, it can instruct the terminal to activate one of the SPSs, and according to the activated SPS configuration to receive downlink information.

In some cases, some terminals fail to correctly decode the instructions sent by the network-side device, resulting in failure to correctly determine the SPS that needs to be activated. The network-side device can determine whether the terminal has correctly decoded the instructions based on the information fed back by the terminal. When it is determined that the terminal has not correctly decoded the indication, the network side device may instruct the terminal again to reactivate the SPS.

There can be multiple types of SPS configured by the network side device for the terminal. The following embodiment mainly configures the configuration of the group common semi-static scheduling group common SPS and the configuration of the UE-specific semi-static scheduling UE-specific SPS for the network side device for the terminal. , to give an exemplary description of the technical solution of the present disclosure.

For the group common SPS, during the initial activation, the group scheduled-radio network temporary identity GS-RNTI (Group Scheduled-Radio Network Temporary Identity) can be transmitted in the group common physical downlink control channel group common PDCCH (Physical Downlink Control Channel) The scrambled downlink control information DCI (Downlink Control Information) indicates activation. After receiving the indication, the terminal can decode the DCI and determine the RNTI used for decoding, and then determine the need to activate according to the RNTI (specifically, the value of the RNTI) The SPS is group common SPS.

It should be noted that the DCI scrambling described in all the embodiments of the present disclosure may specifically be a cyclic redundancy check (Cyclic Redundancy Check, CRC) of the scrambled DCI, and the present disclosure is referred to as DCI scrambling for short.

The terminal may be a terminal supporting MBS (Multicast Broadcast service, multicast broadcast service), and the terminal may also support a unicast (unicast) service.

The above group common SPS can be configured to the terminals of the same group (group), but due to different terminals belonging to the same group, the channel transmission conditions can also be different, so some terminals can correctly demodulate and determine the RNTI, while some terminals can not. Demodulate and determine the RNTI. The terminal that correctly demodulates and determines the RNTI can return confirmation information ACK to the network side device, and the terminal that fails to correctly demodulate and determine the RNTI can return non-confirmation information NACK to the network side device, and the network side device can according to the received feedback Determine which terminals are not correctly demodulated to determine the RNTI.

For a terminal whose RNTI has not been correctly demodulated, the network side device can re-instruct the terminal to reactivate the group common SPS. At present, a way to re-instruct the terminal is realized through the user equipment-specific physical downlink control channel UE-specific PDCCH, but currently the UE-specific PDCCH is mainly used to activate the user equipment-specific semi-persistent scheduling UE-specific SPS, When using the UE-specific PDCCH to activate the group common SPS, it is difficult for the terminal to distinguish which type of SPS the UE-specific PDCCH activates.

As shown in Figure 1, the reactivation determination method of the semi-persistent scheduling may include the following steps:

In step S101, the type of the reactivated semi-persistent scheduling is determined according to the instruction of the network side device.

In one embodiment, when the network side device instructs the terminal to reactivate the SPS, it can indicate the type of SPS to be reactivated by the terminal, so that the terminal can accurately determine the type of SPS that needs to be reactivated, and then reactivate the corresponding type of SPS , and successfully communicate with network-side equipment through the configuration of the reactivated SPS, such as receiving downlink information, to avoid reactivating the wrong type of SPS, resulting in failure to communicate with network-side equipment smoothly and affecting the communication effect.

In one embodiment, the type includes at least one of the following: group common semi-persistent scheduling group common SPS; user equipment exclusive semi-persistent scheduling UE-specific SPS.

The network side device may instruct the terminal to reactivate the group common SPS or reactivate the UE-specific SPS. When the terminal determines to reactivate the group common SPS according to the instructions, it can reactivate the group common SPS, and communicate with the network side device according to the configuration of the group common SPS; when the terminal determines to reactivate the UE-specific SPS according to the instructions, it can reactivate the UE-specific SPS. specific SPS, and communicate with the network side device according to the UE-specific SPS configuration;

In one embodiment, the indication of the network side device includes at least one of the following:

Explicit instruction, implicit instruction.

The network-side device can instruct the terminal in an explicit way, such as sending one or more pieces of information to the terminal, and the content carried in the information directly indicates the type; the network-side device can instruct the terminal in the following ways: Implicit indication, such as sending information to the terminal, the information has other functions and is not directly used to indicate the type, the terminal can determine the type of SPS that needs to be reactivated according to the information in some ways, for example, the information is for the user The DCI in the device-specific search space USS (User-Specific Search Space), the DCI is scrambled by the RNTI, the DCI is not used to indicate the type, but the terminal can determine the type according to the RNTI of the scrambled DCI.

As shown in Figure 2, for example, for a terminal that supports MBS, the network side device configures at least a group common SPS configuration for the terminal, where the group common SPS is surrounded by 5 time slot slots, such as the physical time slot of the group common SPS in Figure 2 One Physical Downlink Shared Channel (PDSCH) is in slot#n+1, and the next one is in slot#n+6, with an interval of 5 slots.

The network side device initially activates the group common SPS at slot #n, for example, sends the group common PDCCH to the terminals belonging to the same group at slot #n, and the DCI in the group common PDCCH is scrambled by GS-RNTI. If the terminal correctly demodulates and determines the RNTI corresponding to the DCI, it can communicate with the network side device according to the configuration of the group common PDCCH, for example, receiving the PDSCH of the group common SPS at slot#n+1 and slot#n+6.

The network side device can determine whether the terminal correctly demodulates and determines the RNTI corresponding to the DCI according to the information fed back by each terminal. The device determines that the terminal has not correctly demodulated to determine the RNTI.

In addition, if the network side device is also configured with UE-specific SPS configuration for the terminal, it can transmit DCI scrambled by CS-RNTI in the USS for reactivation.

The following embodiments mainly illustrate several ways in which the network side device instructs the terminal to reactivate the group common SPS on the basis of the embodiment shown in FIG. 2 .

Fig. 3 is a schematic flowchart of another method for determining reactivation of semi-persistent scheduling according to an embodiment of the present disclosure. As shown in FIG. 3, the type of semi-persistent scheduling determined for reactivation according to the instruction of the network side device includes:

In step S301, receive downlink control information DCI for activating SPS transmitted in the user equipment dedicated search space USS;

In step S302, the type is determined according to the RNTI that scrambles the DCI.

It should be noted that, for whether the DCI is DCI for activating SPS, the terminal may judge in an agreed manner, and the judgment condition includes at least one of the following:

The CRC of DCI is scrambled by CS-RNTI, or scrambled by GS-RNTI;

The NDI (New data indicator, new data indication) field in DCI is 0;

If DFI exists in DCI, the DFI field (DCI format indicator, DCI format indicator) is 0;

The DCI includes a PDSCH to HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat request) feedback timing indication field, which is used to indicate available uplink subframes.

After making the above judgment, the terminal can further judge whether the validation (authentication) field in the DCI satisfies the activation condition. If the activation condition is met, the terminal can then use the high-level configuration information corresponding to the configuration of the SPS to be activated and the dynamic scheduling information in the DCI. Determine how to receive the PDSCH of the SPS.

In an embodiment, the network side device may transmit DCI for activating SPS in USS, for example, the DCI is carried in UE-specific PDCCH, to instruct terminals that have not correctly demodulated and determined RNTI to reactivate group common SPS.

The corresponding relationship between the RNTI and the type of the SPS may be pre-stored in the terminal, for example, stipulated in the protocol or pre-configured by the network side device. After receiving the DCI used to activate the SPS in the USS, the terminal can determine the RNTI that scrambles the DCI, for example, descramble the DCI through the RNTI, and the RNTI that successfully descrambles the DCI corresponds to the RNTI that scrambles the DCI , so that the RNTI for scrambling the DCI can be determined according to the RNTI for successfully descrambling the DCI, and then the SPS corresponding to the RNTI for scrambling the DCI can be determined according to the RNTI for scrambling the DCI and the corresponding relationship type.

As shown in Figure 4, the terminal did not correctly demodulate and determine the RNTI corresponding to the DCI used to activate the group common SPS in slot #n, and the network side device can send UE-specific PDCCH (which carries RNTI scrambled DCI) to the terminal, For example, it is sent in slot#n+5 to instruct the terminal to reactivate the group common SPS. After the terminal reactivates the group common SPS, it can receive the PDSCH of the group common SPS in slot#n+6 according to the configuration of the group common SPS.

In one embodiment, the determining the type according to the RNTI scrambling the DCI includes:

In response to the RNTI scrambling the DCI being the first RNTI, determine to reactivate the group common SPS; and/or in response to the RNTI scrambling the DCI being the second RNTI, determine to reactivate the UE-specific SPS.

The corresponding relationship between RNTI and SPS type can be pre-stored in the terminal, for example, as stipulated in the agreement or pre-configured by the network side device. In this corresponding relationship, the first RNTI corresponds to group common SPS, and the second RNTI corresponds to UE-specific SPS.

Wherein, the first RNTI and/or the second RNTI may be different from the RNTI in the related art, or the RNTI in the related art may be multiplexed, and may be specifically selected according to needs.

In one embodiment, the first RNTI is different from the GS-RNTI used to scramble the DCI for the initial activation of the group common SPS, and/or scrambled with the DCI used for the initial activation of the UE-specific SPS The CS-RNTI (Configured Scheduled-Radio Network Temporary Identity, Configured Scheduled-Radio Network Temporary Identity) is different.

The DCI for the initial activation of the group common SPS is in the CSS (Common Search Space), and the information transmitted in the CSS can be received by multiple terminals; the DCI for the initial activation of the UE-specific SPS is in the USS, Information transmitted in the USS is generally only received by designated terminals.

However, in some cases, there will be a partial overlap between the CSS and the USS. If the DCI transmitted in the USS for activating the SPS happens to be located in this overlapping part, it will cause the transmission in the USS to activate the SPS. The DCI is received by multiple terminals. If the RNTI of the DCI used to activate the SPS transmitted in the USS is scrambled, it is the same as the CS-RNTI used to scramble the DCI initially activated by the UE-specific SPS, or the same as the CS-RNTI used for the group The GS-RNTI scrambled by the DCI initially activated by the common SPS is the same, which may cause other terminals to activate the corresponding SPS according to the RNTI determined by successful decoding after receiving the DCI transmitted in the USS for activating the SPS, causing other terminals to False activation of SPS.

Therefore, based on this embodiment, a new RNTI can be introduced as the first RNTI, which is different from the GS-RNTI that scrambles the DCI initially activated by the group common SPS, and the CS that scrambles the DCI initially activated by the UE-specific SPS. -RNTI, so as to avoid misactivation of SPS by other terminals.

In one embodiment, the first RNTI is the same as the GS-RNTI used for scrambling the DCI for initial activation of the group common SPS.

Although the introduction of a new RNTI as the first RNTI can avoid misactivation of SPS by other terminals, the adjustment of the communication architecture is relatively large by the introduction of a new RNTI, and the misactivation of SPS generally only occurs between CSS and USS. There will be partial overlap between CSS and USS, and it is not very common that there will be partial overlap between CSS and USS.

Therefore, this embodiment can also multiplex the GS-RNTI that scrambles the DCI initially activated by the group common SPS to scramble the DCI transmitted in the USS for activating the SPS, and the terminal receives the DCI transmitted in the USS for After activating the DCI of the SPS, after determining that the RNTI scrambling the DCI is the GS-RNTI, it can be determined that the network side device needs to instruct to reactivate the group common SPS. Accordingly, it is advantageous to reduce modifications to the communication framework.

Fig. 5 is a schematic flowchart of another method for determining reactivation of semi-persistent scheduling according to an embodiment of the present disclosure. As shown in FIG. 5, the type of semi-persistent scheduling determined for reactivation according to the instruction of the network side device includes:

In step S501, in response to receiving the DCI for activating the group common SPS in the USS, it is determined to reactivate the group common SPS when the DCI scrambled by the CS-RNTI is received in the USS.

In one embodiment, the protocol can pre-agreed on the terminal. When the terminal supports receiving DCI for activating group common SPS in the USS, when the terminal receives the DCI scrambled by CS-RNTI in the USS, it defaults to It is the network side device instructing the terminal to reactivate the group common SPS.

Then, when the terminal itself supports receiving DCI for activating group common SPS in the USS, if it receives DCI scrambled by CS-RNTI in the USS, the network side device can instruct the terminal to reactivate the group common SPS by default, so that Reactivate the group common SPS without thinking that the network side device instructs the terminal to reactivate the UE-specific SPS.

In one embodiment, the terminal is configured with group common SPS and not configured with UE-specific SPS.

When the terminal receives the DCI scrambled by CS-RNTI in the USS, it will not think that the network side device instructs the terminal to reactivate the UE-specific SPS, that is, it will not reactivate the UE-specific SPS, which will lead to a certain extent Even if the UE-specific SPS configuration is configured for the terminal, UE-specific SPS cannot be reactivated smoothly. Therefore, in this case, the network side device can choose to configure the group common SPS configuration for the terminal instead of UE-specific SPS configuration for the terminal. Specific SPS configuration reduces resource waste.

Of course, the network-side device can also configure both the group common SPS configuration and the UE-specific SPS configuration for the terminal, which can be selected according to actual needs.

Fig. 6 is a schematic flowchart of another method for determining reactivation of semi-persistent scheduling according to an embodiment of the present disclosure. As shown in Figure 6, the terminal is configured with group common SPS and/or UE-specific SPS on the first frequency domain resource, and the type of semi-persistent scheduling determined to be reactivated according to the instruction of the network side device includes:

In step S601, the type is determined according to the RNTI that scrambles the DCI transmitted by the network side device on the second frequency domain resource.

It should be noted that the DCI may be located in the USS of the terminal, and in the case that the second frequency domain resources are exclusively allocated to the terminal, then the DCI may be located in the USS of the terminal or may not be located in the USS of the terminal. in the USS of the terminal.

In an embodiment, the group common SPS and/or UE-specific SPS configured by the network side device for the terminal may be configured for the first frequency domain resource. In this case, the network side device may transmit the DCI scrambled through the RNTI on the second frequency domain resource to indicate the type of SPS that the terminal needs to reactivate.

Of course, the network side device may also transmit DCI scrambled by RNTI on the first frequency domain resource to indicate the type of SPS that the terminal needs to reactivate, which may be specifically selected by the network side device according to needs.

In an embodiment, the first frequency domain resource includes a first component carrier CC, and the second frequency domain resource includes a second CC; and/or the first frequency domain resource includes a first bandwidth part BWP, so The second frequency domain resource includes a second BWP.

As shown in Figure 7, for example, the network side device configures group common SPS and UE-specific SPS for the terminal on the first CC, and the terminal fails to correctly demodulate and determine the RNTI corresponding to the DCI used to activate the group common SPS in slot#n, The network side device can send UE-specific PDCCH (which carries RNTI scrambled DCI) to the terminal on the second CC, for example, in slot#n+5, to instruct the terminal to reactivate the group common SPS on the first CC , after reactivating the group common SPS, the terminal can receive the PDSCH of the group common SPS at slot#n+6 according to the configuration of the group common SPS.

For example, the network side device configures group common SPS and UE-specific SPS for the terminal on the first BWP, and the network side device can send DCI scrambled by RNTI to the terminal in the USS on the second BWP to instruct the terminal to reactivate group common SPS, or reactivate UE-specific SPS.

It should be noted that, in this embodiment, the format of the DCI can be DCI format 1_1 or DCI format 1_2, since the DCI in these two formats can carry information about the frequency domain, it is convenient to indicate the frequency where the SPS that needs to be activated is located. Domain resources, for example, indicate the CC and BWP where the SPS that needs to be activated resides.

Fig. 8 is a schematic flowchart of another method for determining reactivation of semi-persistent scheduling according to an embodiment of the present disclosure. As shown in FIG. 8 , the type of the reactivated semi-persistent scheduling determined according to the instruction of the network side device includes:

In step S801, DCI for activating the SPS transmitted in the USS is received;

In step S802, the type is determined according to the identifier of the USS where the DCI is located.

In an embodiment, the corresponding relationship between the USS identifier (for example, ID) and the type of the SPS may be pre-stored in the terminal, for example, stipulated in the protocol or pre-configured by the network side device.

After receiving the DCI for activating the SPS in the USS, the terminal can determine the identifier of the USS where the DCI is located, and then identify the corresponding SPS type according to the correspondence between the identifier and the type of the SPS.

As shown in Figure 9, for example, the network side device configures at least two USS identifiers for the terminal, which are USS#1 and USS#2 respectively. Corresponding to UE-specific SPS, USS#2 corresponds to group common SPS.

The terminal did not correctly demodulate and determine the RNTI corresponding to the DCI used to activate the group common SPS in slot#n. The network side device can send UE-specific PDCCH to the terminal in slot#n+5, and the DCI scrambled by the RNTI carried in it is in In the USS corresponding to USS#2. After receiving the DCI carried by the UE-specific PDCCH transmitted in slot#n+5, the terminal can determine that the DCI is in the USS corresponding to USS#2, and then can determine that USS#2 corresponds to the group common SPS, thereby activating the group common SPS. Receive downlink information on the PDSCH corresponding to the group common SPS (for example, at slot#n+6).

In addition, the terminal can also send UE-specific PDCCH to the terminal in the USS corresponding to USS#1 as needed, for example, send UE-specific PDCCH to the terminal on slot#n+4, and the terminal receives the UE-specific PDCCH transmitted on slot#n+4 The DCI carried by the UE-specific PDCCH can determine that the DCI is in the USS corresponding to USS#1, and then it can be determined that the USS#1 corresponds to the UE-specific SPS, thereby activating the UE-specific SPS, and then the PDSCH corresponding to the UE-specific SPS ( For example, it is located at slot#n+7) to receive downlink information.

In the above-mentioned embodiments, the way in which the network side device instructs the terminal to activate which SPS is mainly an implicit indication method, that is, the DCI is not directly used to indicate the type of SPS that the terminal needs to activate, but is indicated by scrambling the RNTI of the DCI . The following embodiments mainly illustrate the technical solutions of the present disclosure by way of explicit indication.

In an embodiment, the determining the type of the reactivated semi-persistent scheduling according to the instruction of the network side device includes:

The type is determined according to the indication information sent by the network side device.

In one embodiment, the indication information includes at least one of the following: medium access control layer control element MAC CE; radio access control RRC signaling; DCI.

In an embodiment, the network side device may indicate the type of SPS that the terminal needs to activate by means of an explicit indication, for example, sending one or more pieces of indication information to the terminal, and the content carried in the indication information is to directly indicate the type of. Wherein, the instruction information can be sent in the form of MAC CE, can also be sent in the form of RRC signaling, and can also be sent in the form of DCI, which can be selected according to needs.

Fig. 10 is a schematic flowchart of a method for reactivating semi-persistently scheduled according to an embodiment of the present disclosure. The reactivation method of semi-static scheduling shown in this embodiment can be performed by network-side devices, and the network-side devices can communicate with terminals, including but not limited to mobile phones, tablet computers, wearable devices, sensors, Internet of Things equipment and other communication devices. The network-side equipment includes but is not limited to network-side equipment in communication systems such as 4G, 5G, and 6G, such as base stations and core networks.

In one embodiment, the network side device can configure one or more sets of SPS configurations for the terminal, and when it needs to use one of the SPSs, it can instruct the terminal so that the terminal activates one of the SPSs, and according to the activated SPS configuration to receive downlink information.

There can be various types of SPS configured by the network side device for the terminal. The following embodiment mainly configures the configuration of the group common semi-static scheduling group common SPS and the configuration of the UE-specific semi-static scheduling UE-specific SPS for the network side device for the terminal. , to give an exemplary description of the technical solution of the present disclosure.

The above group common SPS can be configured to the terminals of the same group (group), but because different terminals belonging to the same group, the channel transmission conditions can also be different, so some terminals can correctly demodulate and determine the RNTI, while some terminals can not. Demodulate and determine the RNTI. The terminal that correctly demodulates and determines the RNTI can return confirmation information ACK to the network side device, and the terminal that fails to correctly demodulate and determine the RNTI can return non-confirmation information NACK to the network side device, and the network side device can according to the received feedback Determine which terminals are not correctly demodulated to determine the RNTI.

For a terminal whose RNTI has not been correctly demodulated, the network side device can re-instruct the terminal to reactivate the group common SPS.

As shown in Figure 10, the reactivation method of the semi-persistent scheduling may include the following steps:

In step S1001, determine the type of semi-persistent scheduling SPS that the terminal is expected to reactivate;

In step S1002, an instruction is given to the terminal to enable the terminal to determine the type.

In one embodiment, when the network side device instructs the terminal to reactivate the SPS, it can determine the type of the semi-persistent scheduling SPS that the terminal is expected to reactivate as needed, and then indicate the type of the SPS reactivated by the terminal. Determine the type of SPS that needs to be reactivated, and then reactivate the corresponding type of SPS, and successfully communicate with the network side equipment through the configuration of the reactivated SPS, such as receiving downlink information, to avoid reactivating the wrong type of SPS and causing failure to communicate with the network The side device communicates smoothly, affecting the communication effect.

In step S1101, determine the radio network temporary identifier RNTI for scrambling the downlink control information DCI for activating the SPS in the user equipment dedicated search space USS according to the type;

In step S1102, scrambling the DCI through the determined RNTI;

In step S1103, the USS transmits the DCI to the terminal, so that the terminal determines the type according to the RNTI that scrambles the DCI.

The CRC of DCI is scrambled by CS-RNTI, or scrambled by GS-RNTI;

The NDI (New data indicator, new data indication) field in DCI is 0;

After making the above judgment, the terminal can further judge whether the validation (verification) field in the DCI satisfies the activation conditions. If the activation conditions are met, the high-level configuration information corresponding to the configuration of the SPS that needs to be activated and the dynamic scheduling information in the DCI to determine how to receive the PDSCH of the SPS.

In one embodiment, the determining the RNTI for scrambling the DCI in the USS according to the type includes:

In response to expecting the terminal to reactivate group common SPS, scrambling the DCI through the first RNTI; and/or in response to expecting the terminal to reactivate UE-specific SPS, scrambling the DCI through the second RNTII.

The network-side device and the terminal may pre-store the correspondence between the RNTI and the type of the SPS. In the correspondence, the first RNTI corresponds to the group common SPS, and the second RNTI corresponds to the UE-specific SPS. When the network side device needs to instruct the terminal to reactivate the group common SPS, it can scramble the DCI through the first RNTI, and when it needs to instruct the terminal to reactivate the UE-specific SPS, it can scramble the DCI through the second RNTI.

In one embodiment, the first RNTI is different from the GS-RNTI used to scramble the DCI for the initial activation of the group common SPS, and/or different from the GS-RNTI used for scrambling the DCI for the initial activation of the UE-specific SPS CS-RNTI is different.

In step S1202, the USS transmits the DCI to the terminal, so that the terminal determines to reactivate the group common SPS according to the CS-RNTI scrambling the DCI.

Then when it is determined that the terminal itself supports receiving DCI for activating the group common SPS in the USS, if the terminal needs to reactivate the group common SPS, when it can receive the DCI scrambled by CS-RNTI in the USS, the terminal receives the DCI in the USS After receiving the DCI scrambled by CS-RNTI, the network-side device can instruct the terminal to reactivate the group common SPS by default, thereby reactivating the group common SPS, instead of thinking that the network-side device instructs the terminal to reactivate the UE-specific SPS.

In step S1402, the USS corresponding to the identifier transmits the DCI scrambled by the CS-RNTI to the terminal, so that the terminal determines the type according to the identifier of the USS where the DCI is located.

In an embodiment, the network-side device and the terminal may pre-store the correspondence between the identifier (for example, ID) of the USS and the type of the SPS. The network-side device can first determine the type of SPS that needs to be reactivated by the terminal, and then query the USS ID corresponding to the determined type according to the correspondence between the USS ID and the SPS type, and then can correspond to the queried USS ID. The DCI used to activate the SPS is transmitted to the terminal in the USS. After receiving the DCI for activating the SPS in the USS, the terminal can determine the identifier of the USS where the DCI is located, and then identify the corresponding SPS type according to the correspondence between the identifier and the type of the SPS.

As shown in Figure 9, for example, the network side device configures at least two USS identifiers for the terminal, which are USS#1 and USS#2 respectively. In the corresponding relationship between the USS identifier stored in the terminal and the type of SPS, USS#1 Corresponding to UE-specific SPS, USS#2 corresponds to group common SPS.
