Detailed ways

For the conditional PCell handover scenario with PSCell addition or change, only cell-level execution conditions are configured. Taking PCell as an example, when the execution conditions of PCell are met, the UE still cannot determine the appropriate PSCell to perform PSCell addition or change. , which will cause the UE to only perform PCell handover, or the PSCell accessed by the UE is not the optimal PSCell or fails, resulting in network performance degradation. Similarly, when the execution conditions of the PSCell are met first, the UE still cannot determine a suitable PCell for handover, which will make the UE only able to add or change the PSCell, or the PCell accessed by the UE is not the optimal PCell or directly resulting in access failure.

The character "/" generally indicates that the contextual objects are an "or" relationship.

The term "plurality" in the embodiments of the present disclosure refers to two or more, and other quantifiers are similar.

The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

In order to facilitate a clearer understanding of the various embodiments of the present disclosure, some relevant background knowledge is firstly introduced as follows.

(1) Main idea of CHO/CPAC switching

In order to improve the robustness and reliability of mobility, 3GPP R16 introduced conditional handover and PSCell condition change in the secondary node (Secondary Node, SN) without the participation of the master node (Master Node, MN), and 3GPP R17 introduced the SN Conditions between PSCells are changed, and conditions for PSCells are added.

Whether it is CHO, the condition of PSCell within SN is changed, the condition of PSCell between SNs is changed, or the condition of PSCell is added, the main idea is that the network side pre-configures multiple target cells for the UE, that is, the configuration information of the target cell and the execution The condition is sent to the UE. When the UE receives the configuration information of the target cell, it will not immediately execute the handover or PSCell change or PSCell addition like the traditional handover, PSCell change or PSCell addition, but will save the received configuration and save the configuration options The cell performs measurement and evaluation until there is a cell that meets the execution conditions, and the UE executes the stored reconfiguration message corresponding to the cell, and performs the corresponding handover or PSCell change or PSCell addition process, that is, completes downlink synchronization and triggers random access. into the target PCell or PSCell.

R16 only supports the network side to configure CHO or CPAC for the UE alone, that is, the UE only judges whether the PCell handover condition is met when configuring CHO, and only executes the PCell handover process, that is, the PCell handover process does not accompany the addition or change of the PSCell, or only when CPAC is configured It is judged whether the execution condition of adding or changing the PSCell is satisfied, so that only the adding or changing process of the PSCell is executed, that is, the adding or changing process of the PSCell is not accompanied by the switching process of the PCell.

(2) Multi-beam

The New Radio (NR) system supports multiple beams, and different beams can be identified by the Synchronization Signal Block (SSB) index, and the UE can also measure the channel state information reference signal (Channel State Information-Reference Signal , CSI-RS) signal to perform beam adjustment, and the network can determine the serving beam by measuring the strength of the reference signal.

R17 or R18 is expected to introduce research on the coexistence scenario of CHO and multi-radio access dual connectivity (Multi-RAT Dual Connectivity, MRDC). Compared with the CHO scenario, adding or changing a PSCell while performing conditional PCell handover can be performed while performing PCell handover. Establishing the MRDC at the same time can reduce the time delay of establishing the MRDC, and help to improve the network throughput, or complete the mobility management of the PSCell while maintaining the PCell connection.

In addition, according to the current research conclusion of CHO, the network side can only configure cell-level execution conditions for the UE. However, in a conditional PCell handover scenario with PSCell addition or change, if only cell-level execution conditions are configured, when the PCell execution conditions are met, the UE still cannot determine that the PSCell addition or change is satisfied. This will cause the UE to only perform PCell handover, or the PSCell accessed by the UE is not an optimal PSCell or the handover fails, thereby degrading network performance. The same problem also exists when the execution conditions of the PSCell are met first, and the UE still cannot determine a suitable PCell for handover, which will make the UE only perform addition or change of the PSCell, or the PCell accessed by the UE is not optimal PCell may directly cause access failure.

In view of the above problems, each embodiment of the present disclosure provides a solution, the core idea of which is: for the conditional PCell switching scenario with PSCell addition or change, the execution condition related to beam information is introduced, that is, the network side can additionally be a candidate The execution conditions related to beam information corresponding to the configuration of the target PCell. When the cell-level execution condition of a certain PCell is satisfied, the UE can further select the best PSCell from the candidate PSCells associated with the PCell according to the execution condition related to the beam information, and simultaneously initiate The access of the PSCell. This solution is also applicable when the measurement target is a PSCell, and the cell-level execution conditions and additional beam information-related execution conditions are configured for the candidate target PSCell. When it is determined that the PSCell is added or changed, the appropriate PCell access is selected according to the beam information, thereby Improve the success rate and reliability of switching.

It should be noted that, for the convenience of subsequent discussions, the embodiments of the present disclosure are mainly described by taking the measurement target cell as the PCell as an example. Of course, those skilled in the art can know that the technical solutions of the various embodiments of the present disclosure are not limited to the measurement target cell The scenario where the cell is the PCell is also applicable to the scenario where the measurement target cell is the PSCell.

In each embodiment of the present disclosure, the measurement target cell is a PCell or PSCell; the associated target cell is: for the scenario where the measurement target cell is a PCell, the associated target cell is a PSCell; for the scenario where the measurement target cell is a PSCell , the associated target cell is a Pcell.

For the scenario where the measurement target cell is a PCell, the target measurement node is the target MN; for the scenario where the measurement target cell is a PSCell, the target measurement node is the target SN.
