Optionally, in the embodiment of the disclosure, the system information area includes one or more cells, and system information of each cell (Cell) in a system information area is completely the same or mostly the same; or the system information area includes one Or multiple network side devices, and the system information of each network side device in a system information area is completely the same or mostly the same.

In this implementation manner, the system information area may be defined to include one or more cells, and the system information of each cell is identical or mostly the same, that is, it may be understood as one or more system informations that are identical or mostly identical. Defined as a system information area. The system information area has a mapping relationship with one or more cells. In addition, the cell may be a cell under a 5G NR NB, or may be a cell under one or more TRPs managed and controlled by the CU. The cell has a physical cell identifier (PCI), and a cell can be identified by means of frequency + PCI. The UE can search for the cell and the PCI at the corresponding frequency. When the SIA contains only one In the case of a cell, the SIA is equivalent to a cell. In addition, one SIA may contain multiple cells at different frequency points. For example: as shown in Figure 3.

In addition, in this implementation manner, the defined system information area may include one or more network side devices, and the system information of each network side device is identical or mostly the same, that is, it may be understood as one or more system information. An identical or mostly identical network side device is defined as a system information area. The system information area has a mapping relationship with one or more network side devices. For example, an SIA may include one or more TRPs, and the TRP has a physical layer identifier (for example, a TRP ID), and the UE may search for the TRP and the TRP ID through a physical layer signal, for example, by using a synchronization signal (Sync Signal) or a reference signal. (RS, Reference Signal), etc. Search for the TRP and TRP ID. In addition, one SIA can also contain multiple TRPs at different frequencies. In this embodiment, the system information area may be specifically as shown in FIG. 3.

In addition, the SIA has a SIA ID, which may be a physical layer identifier or a high layer identifier. When the SIAID is the physical layer identifier, the UE may search for the SIA and the SIA ID by using a physical layer signal (for example, a synchronization signal, a reference signal, etc.); when the SIA ID is a high layer identifier, the network side device may notify the UE of the SIA ID and the Cell. Or mapping relationship between TRPs, for example: SIA1: Cell1, Cell2; SIA2: Cell3 or SIA3: TRP1; SIA4: TRP2, TRP3, TRP4.

In addition, the system information of each cell or network side device in the SIA is mostly the same, and may be: the SIB is the same, and the MIB is different. Therefore, when the Cell or the TRP is replaced, the MIB needs to be re-read; the SIB may be the same, but the SIB of the network side periodic broadcast and the SIB ratio of the on-demand are different. The SIB here may be other system information blocks except the MIB in the system information.

In addition, it should be noted that the system information area defined by this embodiment may be any system information area in the embodiment of the present disclosure, for example, the current SIA and the foregoing neighboring area SIA.

Optionally, in the neighboring area SIA, the UE does not acquire the same system information in the neighboring area SIA and in the current SIA.

In this implementation manner, after the UE accesses or moves to the neighboring area SIA, the UE does not need to obtain the same system information in the neighboring area SIA and the current SIA, because the UE has acquired the current SIA. These system information. Therefore, in the neighboring area SIA, the UE only needs to acquire system information in the neighboring area SIA that is different from the current SIA.

Optionally, the method further includes: the identifier of the neighboring area SIA is a physical layer identifier, and the UE If the physical layer identifier of the neighboring area SIA is detected, the neighboring area SIA is determined. In this implementation manner, when the identifier of the neighboring area SIA is the physical layer identifier, the UE detects the physical identifier and determines the neighbor. District SIA. For example, when the UE moves, after the UE detects the SIA ID of the neighboring SIA, it considers that the neighboring SIA is found.

Optionally, the method further includes: the identifier of the neighboring area SIA is a high-level identifier, and the UE detects the cell identifier of the neighboring cell, and determines whether the cell identifier is in the cell list corresponding to the current SIA, If not, it is determined that the neighboring area SIA is found.

In this implementation manner, the identifier of the neighboring area SIA can be implemented as a high-level identifier, and the UE determines whether the neighboring area SIA is found by detecting the cell identifier of the neighboring cell. For example, when the UE moves, the UE determines the current SIA (or the SIA) corresponding to the Cell list by obtaining the mapping relationship between the SIA ID and the Cell. After the UE detects the PCI of the neighboring cell, it compares with the known Cell list. If it is not in the Cell list corresponding to the current SIA, the UE is considered to belong to the adjacent SIA, that is, the adjacent SIA is considered to be found.

Optionally, the method further includes: the identifier of the neighboring area SIA is a high-level identifier, and the UE detects the device identifier of the neighboring network side device, and determines whether the device identifier is in the device list corresponding to the current SIA. If not, it is determined that the neighboring area SIA is found.

In this implementation manner, the identifier of the neighboring area SIA can be implemented as a high-level identifier, and the UE determines whether the neighboring area SIA is found by detecting the device identifier of the neighboring network side device. For example, when the UE moves, the UE determines the TRP list corresponding to the SIA by obtaining the mapping relationship between the SIA ID and the TRP. After the UE detects the TRP ID of the neighboring TRP, it compares it with the known TRP list. If it is not in the TRP list corresponding to the SIA, it considers that the TRP belongs to the adjacent SIA, that is, it considers that the adjacent SIA is found.

Optionally, the foregoing UE receives the indication information of the neighboring system information sent by the network side device, where the UE reports the neighboring area measurement result corresponding to the neighboring area SIA to the network side device, to receive the network side. The neighboring system information difference indication information returned by the device in response to the neighboring area measurement result.

In this implementation manner, the neighboring area system information similarity indication information is obtained by using the neighboring area measurement result, that is, the network side device receives the neighboring area measurement result, and may return the neighboring area system information similarity indication information to the UE. Wherein, the neighboring area measurement result can determine the neighboring area system information Obtain. For example, the neighboring area measurement result includes: an identifier of the neighboring area SIA; or a physical layer identifier of one or more cells in the neighboring area SIA; or one or more network side apparatuses of the neighboring area SIA The physical layer identification; or the neighboring area measurement result is used to make a mobility decision.

The measurement result of the neighboring area includes the SIA ID of the neighboring area SIA, and the indication information of the neighboring area system information may be the neighboring area system information similarity indication information corresponding to the neighboring area SIA, where the neighboring area system information similarity indication may be a neighbor Zone SIB similarity indication list.

If the neighboring area measurement result includes the physical layer identifier of the Cell or the TRP in the neighboring area SIA, the neighboring area system information similarity indication information may be the neighboring area system information similarity indication information corresponding to the Cell or the TRP in the adjacent SIA, where The neighboring system information difference indication may be a neighboring SIB similarity indication list.

In addition, if the neighboring cell measurement result is used to perform a mobility decision (for example, a handover decision, a TRP change decision), the UE acquires the target SIA delivered by the network side device, and the neighboring cell system information and the same indication information of the target cell or the target TRP, that is, The neighboring system information similarity indication information of the neighboring area SIA is sent. For example, the UE acquires the target SIA, the neighboring cell SIB similarity indication list corresponding to the target cell or the TRP in an RRC message (for example, a handover command message, a TRP change message). In addition, in this embodiment, the UE may be a UE in a connected state.

Optionally, the foregoing UE receives the indication information of the neighboring system information sent by the network side device, where the UE sends a request message to the network side device, to receive the location returned by the network side device in response to the request message. The neighboring area system information similarity indication information, where the request message is used to acquire the neighboring area system information similarity indication information; or the UE acquires the neighboring area system included in the system information broadcast by the network side device Information similarities and indications indicate information.

In this implementation manner, the UE may send a request to the network side device to obtain the neighboring area system information similarity indication information, and obtain the neighboring area system information similarity indication information in the broadcast system information. For example, the idle state UE or the inactive UE sends a request message, which is used to obtain the neighboring system information and the same information indication information, so that the UE obtains the pre-configured neighboring system information similarity indication information sent by the network side device. Specifically, the UE may perform a request and a response through a random access procedure, and the request message is sent in Msg3, and the response message is received in Msg4. For another example, the idle state UE or the inactive UE acquires pre-configured neighbor system information difference indication information in the system information of the network side periodic broadcast.

In the embodiment, the information about the similarity and dissimilarity information of the neighboring cell system can be pre-configured, and when the network planning is performed in the initial stage of network deployment, the current SIA knows the list of neighboring SIAs, and the list of cells or TRPs in the neighboring zone SIA. For example, the neighboring SIAs of SIA1 are SIA2 and SIA3, then the neighboring SIAs of SIA1 are {SIA2, SIA3}; the neighboring SIAs of SIA1 are SIA2 and SIA3, SIA2 contains Cell3, SIA3 contains TRP1, then the adjacent SIA of SIA1 The list of cells under is {Cell3} or the list of TRPs is {TRP1}

Optionally, the foregoing request message includes: an identifier of the neighboring area system information area; or a physical layer identifier of one or more cells in the neighboring area system information area; or one or more of the neighboring area system information areas The physical layer identifier of the network side device.

In this implementation manner, the UE may send the request message to the network side device, where the request message may include the identifier of the neighboring system information area, or may be a physical layer of one or more cells in the neighbor system information area. The identifier, and may also include a physical layer identifier of one or more network side devices in the neighbor system information area. Therefore, after receiving the request message, the network side device may determine the neighboring area system information area requested by the UE, and send the neighboring area system information similarity indication information to the UE. It should be noted that, the foregoing request message does not include the foregoing identifier information, that is, the network side device pre-configures the neighboring cell system information similarity indication information for the UE.

Optionally, the neighboring system information difference and the same indication information includes the neighboring area system information similarity indication content, or the neighboring area system information similarity indication information further includes: the identifier of the neighboring area SIA, and the neighboring area SIA A cell identifier of one or more cells or a device identifier of one or more network side devices in the neighboring area SIA.

In this implementation manner, the neighboring area system information similarity indication information may include the neighboring area system information similarity indication content. And may also include or exclude the identity of the neighboring area SIA, the cell identity of one or more cells in the neighboring zone SIA, or the device identity of one or more network side devices in the neighboring zone SIA. For example, in the implementation manner of reporting the neighboring area measurement result by the UE described above, the neighboring area system information similarity indication information may include only the neighboring area system information similarity and indication content. The neighboring system information difference indication content is used to indicate the difference between the system information of the current SIA and the system information of the neighboring area SIA.

Optionally, in this implementation manner, the neighboring system information difference indicates that the content is in accordance with system information. The sending mode indicates whether the system information is the same; or the neighboring system information difference indicating content indicates whether the system information is the same through the system information indicating list.

In this embodiment, whether the system information is the same according to the system information transmission manner may be implemented, and whether the system information is the same through the system information indication list may also be implemented. For example, if the neighboring system information difference indication content indicates that the system information is the same according to the system information sending manner, the neighboring area system information similarity indicating content includes indication content for indicating whether the system information of the broadcast transmission is the same, and is used for And indicating that the system information sent by the same is the same indication content; if the neighboring system information is different from the indication content, the system information indication list indicates whether the system information is the same, the neighboring system information difference indication content includes: the same system information The index, the index of the different system information, or the system information indicates a bitmap indicating the same system information and different system information.

For example, the neighboring system information difference indication content may be indicated in the form of a bitmap, for example, 10, indicating that the SIB of the periodic broadcast is the same, and the on-demand SIB is different. Further, when the SIBs of the periodic broadcast are different, the system information of the SIBs that are periodically broadcasted may be different. When the SIBs of the on-demand are different, the system information of the SIBs may be different according to the requirements. The above-mentioned on-demand SIB can be understood as an SIB that is sent by the network side device only when receiving a request sent by the UE.

The index of the same system information is the index of the same system information in the neighboring area SIA and the current SIA, and may be an SIB index list, for example, the same SIB list, for example, {SIB1, SIB2, SIB6, SIB8}. Similarly, the index of the different system information may also be an SIB index list, for example: {SIB3, SIB4, SIB5, SIB7, SIB9, ..., SIB20}. The system information indication bitmap may indicate which system information is the same and which system information is different. For example, the system information indication bitmap may be 11000101000000000000, indicating that SIB1, SIB2, SIB6, and SIB8 are the same, and other SIBs are different.

Optionally, in the foregoing implementation manner, the system information is considered to be the same for the system information that is not included in the current SIA and the neighboring area SIA, or is not available in the current SIA but not in the neighboring area SIA. If the system information is different, the system information is considered to be different; or the system information that is in the neighboring area SIA but not in the current SIA is considered to be different.

In this embodiment, it may be implemented that some special cases in the two system information areas define the same or different system information. For example, if both system information areas do not have SIB10, they are considered the same. Another example For example, if the current SIA has SIB10 and the neighboring area SIA does not, it is considered different.

Optionally, the foregoing UE obtains the system information of the neighboring area SIA according to the information about the neighboring area system information, and includes: if the neighboring area system information similarity indication information indicates system information and neighbors of the current system information area. If the system information of the area system information area is the same, the system information of the current system information area is used as the system information of the neighboring area system information area; or the neighboring area system information similarity indication information indicates the current SIA system. The information is partially the same as the system information of the neighboring area SIA, and the system information of the system information of the current SIA is the same as the system information of the neighboring area SIA, and the system information of the neighboring area SIA is obtained. The system information of the neighboring area SIA is different from the system information of the current SIA.

In this embodiment, if the system information of the current system information area is the same as the system information of the neighbor system information area, the system information of the current system information area may be directly used as the system of the neighbor system information area. The information does not need to be acquired to the neighboring system information area to save the energy consumption and network resources of the UE. In addition, system information that is the same as the system information of the neighboring area SIA in the system information of the current SIA may be implemented, as system information of the neighboring area SIA, and a system that acquires the system information of the neighboring area SIA and the current SIA. Information about different system information. The obtaining the different system information may be that after the UE accesses or moves to the cell or the network side device in the neighboring area SIA, the system or the network side device that accesses or enters acquires different system information. For example, the UE obtains the neighboring cell identifier and the corresponding neighboring cell SIB similarity and inference indication list by using the neighboring cell system information and the similarity indication information, so as to know which of the two SIAs have the same SIB and which SIBs are different. When the UE accesses or enters the neighboring area SIA, the same system information is used as the system information of the new SIA (ie, the neighboring area SIA). For different system information, the UE reads the system information of the new SIA.

For example, the idle state UE or the inactive UE obtains a list of neighboring SIAs that are known on the network side, and the corresponding neighboring cell SIBs are different from the indication list, so as to know which SIBs in the neighboring area SIA are the same and which SIBs are different. Or the idle state UE or the inactive UE obtains a list of the Cell or TRP in the neighboring area SIA that is known by the network side, and the corresponding neighboring area SIB difference indication list, so as to know which SIBs in the neighboring area SIA to which the Cell or TRP list belongs is the same. Which SIBs are different. When the UE moves to a neighboring area SIA indicated in the list, a cell or a neighboring area SIA to which the TRP belongs, the same system information is used as the system information of the new SIA, and the UE reads the new system information for different system information. System information of the SIA.

For another example, the connected state UE obtains the SIA ID of the neighboring cell SIA included in the neighboring cell measurement result, and the corresponding neighboring cell SIB difference and similar indication list, so as to know which SIBs in the neighboring zone SIA are the same and which SIBs are different. Or the connected UE obtains the physical layer identifier of the Cell or the TRP in the neighboring SIA included in the neighboring area measurement result, and the corresponding neighboring area SIB identifier list, so as to know which SIBs in the neighboring SIA to which the Cell or the TRP belongs are the same. Which SIBs are different.

Optionally, in this implementation, the acquiring, by the UE, system information that is different from the system information of the current SIA in the system information of the neighboring area SIA, includes: if different system information includes system information required by the UE, And the UE acquires system information required by the UE in the different system information, where the different system information is system information that is different from system information of the current SIA in system information of the neighboring area SIA; The system information required by the UE is not included in different system information, and the UE does not acquire the different system information.

In this implementation manner, the UE can obtain only the system information required by the UE in the foregoing different system information, thereby reducing the energy consumption of the UE and saving network resources. For example, the different system information includes: {MIB, SIB3, SIB4, SIB5, SIB7, SIB9, ..., SIB20}, and the UE only needs MIB, SIB7, SIB9, so that the UE only needs to acquire MIB, SIB7, SIB9. It should be noted that the system information required by the UE may include on-demand SI required by the UE and broadcasted system information (broadcast SI) required by the UE.

Optionally, in the foregoing implementation manner, the UE receives, by the network side device, the information about the neighboring system information and the same information, and the information about the neighboring system information of the first neighboring area SIA sent by the network side device The indication information and/or the neighboring cell system information dissimilarity indication information of the second neighboring area SIA, where the first neighboring area SIA is the neighboring area SIA that the UE needs to perform handover or change, and the second neighboring area SIA is the The UE performs the reconstructed neighboring area SIA; the UE uses the system information of the system information of the current SIA and the system information of the neighboring area SIA as the system information of the neighboring area SIA, and acquires the neighboring area. The system information of the SIA that is different from the system information of the current SIA, includes: if the UE performs handover or changes successfully, the UE indicates information according to the neighboring system information of the first neighboring area SIA. The system information of the system information of the current SIA that is the same as the system information of the first neighboring area SIA is used as the system information of the first neighboring area SIA, and the system information of the first neighboring area SIA is obtained. With the SIA's Department The system information is different from the system information; or if the UE performs the reconstruction successfully, the UE compares the system information of the current SIA with the second according to the neighboring system information of the second neighboring area SIA The system information of the neighboring area SIA is the same as the system information of the second neighboring area SIA, and the system information of the system information of the second neighboring area SIA is different from the system information of the current SIA; or If the UE performs the re-establishment after the handover or the change is successful, the UE sends the current SIA system information to the second neighbor according to the neighboring system information dissimilarity indication information of the second neighboring area SIA. The system information of the area SIA is the same as the system information of the second neighboring area SIA, and the system information of the second neighboring area SIA is different from the system information of the current SIA.

In this implementation manner, the neighboring system information similarity indication information of the first neighboring area SIA and/or the neighboring area system information similarity indication information of the second neighboring area SIA may be obtained by the UE from the network side device. In this way, the system information of the first neighboring area SIA can be obtained by using the neighboring area system information similarity indication information of the first neighboring area SIA. The information about the neighboring system information of the neighboring area SIA in the foregoing neighboring area may be used to obtain the system information of the second neighboring area SIA.

The reconstruction may be performed by the UE when the radio link fails, or may be performed when the UE performs handover or fails to change. For example, if the UE fails to perform the radio link, the UE selects a neighboring SIA, a neighboring cell or a neighboring SIA to which the TRP belongs, and uses the same system information as the system information of the new SIA. For different system information, the UE reads the system information of the new SIA.

For another example, the UE obtains the SIA ID of the target SIA in the RRC message, and the corresponding neighboring cell SIB difference indication list, so as to know which SIBs in the target SIA are the same and which SIBs are different. Or the UE obtains the physical layer identifier of the target cell or the TRP in the RRC message, and the corresponding neighboring cell SIB difference indication list, so as to know which SIBs in the target cell or the SIA to which the TRP belongs are the same, and which SIBs are different. When the UE accesses the target SIA, the target cell or the SIA to which the TRP belongs, the same system information is used as the system information of the new SIA. For different system information, the UE reads the system information of the new SIA. In addition, the RRC message further includes the neighboring system information dissimilarity indication information at the time of reestablishment. When the UE fails to perform the handover or the TRP fails to be changed, the UE selects a measured neighboring SIA, a cell or a TRP to be associated with the reconfiguration. Adjacent SIA, using the same system information as the new SIA The system information is used. For different system information, the UE reads the system information of the new SIA.

It should be noted that the multiple optional embodiments described in the foregoing embodiments may be implemented in combination with each other, and may be implemented separately.

It should be noted that the present embodiment is an implementation manner of the network side device corresponding to the embodiment shown in FIG. 2, and a specific implementation manner of the embodiment may refer to the related description of the embodiment shown in FIG. 2, so as to avoid duplicating description. This embodiment will not be described again. In this embodiment, the overhead of reducing system information can also be achieved.

The embodiments described in the above embodiments are exemplified by a plurality of examples:

example 1:

For example, the SIA ID is used as the physical layer identifier, and the connected UE performs the neighboring system information acquisition process in the handover process. The workflow is as follows:

Step 1: When the SIA ID is the physical layer identifier, when the connected state UE1 in the SIA1 moves, after detecting that the physical layer identifier of the adjacent SIA is SIAID2, it is considered that the adjacent SIA2 is found (for example, the neighboring area SIA). .

Step 2: The UE1 reports the neighboring area measurement result, which includes the physical layer identifier of the SIA2. The network side device judges that the UE1 wants to switch to the target SIA2 according to the neighboring area measurement result. The UE obtains the neighboring system information and the similarity indication information corresponding to the target SIA2 sent by the network side device in the handover command message, and may be the physical layer identifier of the SIA2 and the corresponding neighboring area SIB similarity indication list, for example, the same SIB index list. SIB1, SIB2, SIB6, and SIB8} indicate that SIB1, SIB2, SIB6, and SIB8 are the same, and other SIBs are different.

Step 3: Since the UE1 obtains the SIA ID of the target SIA2 in the handover command message, and the corresponding neighboring cell SIB difference indication list, it is known that the SIB1, SIB2, SIB6, and SIB8 in the target SIA2 are the same, and the other SIBs are different. When the UE1 accesses the target SIA2, the same system information is used as the system information of the new SIA. For different system information, the UE1 reads the system information of the new SIA.

Example 2:

The example uses the SIA ID as the upper-level identifier, and the connected-mode UE performs the neighboring system information acquisition process in the TRP change process. The workflow is as follows:

Step 1: When the SIA ID is a high-level identifier, the connected state UE2 in the SIA3 obtains the mapping relationship between the SIA ID and the TRP, and determines that the TRP list corresponding to the SIA3 is {TRP1}. When the UE2 moves, the UE2 detects the physical layer identifier of the neighboring TRP (for example, TRP ID2), and compares it with the known TRP list. Since the TRP2 is not in the TRP list corresponding to the SIA3, the TRP is considered to be adjacent. The SIA is considered to have discovered the neighboring area SIA.

Step 2: The UE2 reports the neighboring area measurement result, including the physical layer identifier TRP ID2 of the TRP2. The network side device determines that the UE2 is to be changed to the target TRP2 according to the neighboring area measurement result. The UE2 obtains, in the TRP change message, the neighboring system information and the similarity indication information corresponding to the target TRP2 delivered by the network side, which may be the physical layer identifier of the TRP2 and the corresponding neighboring area SIB similarity indication list, for example, different SIB lists {SIB3, SIB4, SIB5, SIB7, SIB9, ..., SIB20} indicate that SIB3, SIB4, SIB5, SIB7, SIB9, ... SIB19 and SIB20 are different, and other SIBs are the same.

Step 3: The UE2 obtains the physical layer identifier of the target TRP2 in the TRP change message, and the corresponding neighboring area SIB similarity indication list, so that the SIB3, SIB4, SIB5, SIB7, SIB9, SIB19, and SIB20 in the SIA to which the target TRP2 belongs are known to be different. The other SIBs are the same. When the UE 2 accesses the SIA to which the target TRP2 belongs, the same system information is used as the system information of the new SIA. For different system information, the UE reads the system information of the new SIA.

Example 3:

In the example, when the SIA ID is used as the upper layer identifier, the idle state UE obtains the pre-configured neighboring system information and similarity indication information (adjacent Cell) to perform the neighboring system information acquisition process. The workflow is as follows:

Step 1: When the SIA ID is a high-level identifier, the idle state UE3 in the SIA2 obtains the mapping relationship between the SIA ID and the cell, and determines that the cell list corresponding to the SIA2 is {Cell3}. When the UE3 moves, the UE3 detects the physical layer identifier of the neighboring cell (for example, PCI2), and compares it with the known Cell list. Since Cell2 is not in the Cell list corresponding to the SIA2, the Cell2 belongs to the adjacent SIA. That is, it is considered that adjacent SIAs are found.

Step 2: The UE3 sends a request message in the random access process, which is used to obtain the neighboring system information and the same information indication information, and the UE3 obtains the pre-configured neighboring system information and similarity indication information delivered by the network side. The adjacent SIA of SIA2 is SIA1, and SIA1 includes Cell1 and Cell2, then the list of cells under the adjacent SIA known by SIA2 is {Cell1, Cell2}. In the response message, the UE3 obtains the list of the neighboring SIAs under the known neighboring SIAs (Cell1, Cell2) and the corresponding neighboring cell SIBs, for example, 10, indicating that the SIBs of the periodic broadcast are the same, and the on-demand SIBs are different. .

Step 3: The UE3 obtains the same list of the cell list {Cell1, Cell2} and the corresponding neighboring area SIB in the neighboring cell SIA in the response message, so that the SIB of the periodic broadcast in the neighboring area SIA to which the Cell list belongs is the same, on-demand SIB is different. When UE3 moves to the Cell2 indicated in the list When the neighboring area SIA is used, the same system information is used as the system information of the new SIA. For different system information, the UE reads the system information of the new SIA.

Example 4:

When the SIA ID is used as the upper-layer identifier, the inactive UE obtains the pre-configured neighboring system information and similarity indication information (adjacent TRP) to perform the neighboring system information acquisition process. The workflow is as follows:

Step 1: When the SIA ID is a high-level identifier, the inactive UE4 in the SIA4 obtains the mapping relationship between the SIA ID and the TRP, and determines that the TRP list corresponding to the SIA4 is {TRP2, TRP3, TRP4}. When the UE4 moves, the UE4 detects the physical layer identifier of the neighboring TRP (for example, TRP ID1), and compares it with the known TRP list. Since the TRP1 is not in the TRP list corresponding to the SIA4, the TRP1 is considered to be adjacent. SIA, that is, it is considered that adjacent SIAs are found.

Step 2: The UE4 obtains the pre-configured neighboring cell system information similarity indication information of the network side periodic broadcast. The adjacent SIA of SIA4 is SIA3, and SIA3 contains TRP1, then the list of TRPs under the adjacent SIA known by SIA4 is {TRP1}. The UE4 obtains the known neighboring SIA TRP list {TRP1} and the corresponding neighboring SIB difference and similar indication list sent by the network side in the system information message of the periodic broadcast, for example, 11000101000000000000, indicating that the SIB1, the SIB2, the SIB6, and the SIB8 are the same. Other SIBs are different. In particular, this SIA4 does not have SIB8. Since the neighboring area SIB8 is the same, there is no SIB8 in the neighboring area.

Step 3: The UE4 obtains the TRP list {TRP1} under the adjacent SIA and the corresponding neighboring cell SIB similarity indication list in the system information message of the periodic broadcast, so as to know the SIB1, SIB2, SIB6, and SIB8 in the adjacent SIA to which the TRP list belongs. The same, other SIBs are different. When the UE4 moves to the neighboring SIA to which the TRP1 indicated in the list belongs, the same system information is used as the system information of the new SIA. For different system information, the UE reads the system information of the new SIA.
