Description

Condition reconfiguration method, device, apparatus and storage medium

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for conditional reconfiguration.

Background

The current 3GPP (3 rd Generation Partnership Project) protocol only supports that a network side individually configures CHO (Conditional HandOver) or CPAC (Conditional PSCell (Primary Secondary Cell, primary Secondary Cell) Additional/Change for a UE (User Equipment), that is, the UE only determines whether a PCell (Primary Cell ) HandOver Condition is satisfied when configuring the CHO, and thus only executes a PCell HandOver process, that is, the PCell HandOver process does not accompany a PSCell (Primary Secondary Cell) addition or Change, or only determines whether an execution Condition added or changed by the PSCell is satisfied when configuring the cpap, and thus only executes the PSCell addition or Change process, that is, the PSCell addition or Change process does not accompany the PCell (Primary Secondary Cell ) addition or Change process. This may cause the UE to perform only a handover of the PCell or only an addition or change of the PSCell, resulting in a degradation of network performance.

Detailed Description

In a conditional PCell handover scenario with PSCell addition or change, only cell-level execution conditions are configured, and taking a PCell as an example, when the execution conditions of the PCell are met, the UE still cannot determine a suitable PSCell to perform PSCell addition or change, which may cause the UE to only perform handover of the PCell, or cause the PSCell accessed by the UE to be not an optimal PSCell or to fail, thereby causing network performance degradation. Similarly, when the execution condition of the PSCell is satisfied first, the UE still cannot determine a suitable PCell for handover, which may cause the UE to only perform addition or change of the PSCell, or cause the PCell accessed by the UE to be a non-optimal PCell or directly cause access failure.

In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

To facilitate a clearer understanding of the embodiments of the present application, some relevant background information is first presented below.

(1) Main idea of CHO/CPAC switching

In order to improve the robustness and reliability of the movement, conditional handover and PSCell condition change in a SN (Secondary Node) without participation of a MN (Master Node) are introduced into the 3gpp rr 16, PSCell condition change between SNs and conditional PSCell addition are introduced into the 3gpp rr 17.

The main idea of the method is that a network side pre-configures a plurality of target cells for a UE, namely, sends configuration information and execution conditions of the target cells to the UE in advance, no matter the CHO is used, the PSCell condition in the SN is changed, the PSCell condition between SNs is changed, or the PSCell is added. After receiving the configuration information of the target cell, the UE does not perform handover or PSCell change or PSCell addition as in the conventional handover, PSCell change or PSCell addition, but stores the received configuration, and performs measurement and evaluation on the candidate configured cells, until there is a cell satisfying the execution condition, the UE executes the stored reconfiguration message corresponding to the cell to perform the corresponding handover or PSCell change or PSCell addition process, that is, completes downlink synchronization and triggers the random access process to access 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 determines whether the PCell handover condition is satisfied when configuring CHO so as to perform only the PCell handover procedure, that is, the PCell handover procedure is not accompanied by PSCell addition or change, or only determines whether the PSCell addition or change execution condition is satisfied when configuring CPAC so as to perform only the PSCell addition or change procedure, that is, the PSCell addition or change procedure is not accompanied by the PCell handover procedure.

(2) Multi-beam

An NR (New Radio, new air interface) system supports multiple beams, different beams can be identified by SSB (Synchronization Signal Block) index, a UE can also adjust the beams by measuring CSI-RS (Channel State Information-Reference Signal) signals, and a network can determine a serving beam by measuring the strength of the Reference Signal.

A research on a CHO and MRDC (Multi-RAT (Radio Access Technology, radio Access Technology) Dual Connectivity, multiple Radio Access Technology Dual Connectivity) coexistence scenario is expected to be introduced into R17 or R18, and with respect to the CHO scenario, adding or changing PSCell while performing conditional PCell handover can establish MRDC while performing PCell handover, reduce delay in establishing MRDC, and contribute to improving network throughput, or complete mobility management of PSCell while maintaining PCell Connectivity.

In addition, according to the current research conclusion of CHO, the network side can only configure the 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 execution conditions of the PCell are satisfied, the UE still cannot determine that the PSCell addition or change is satisfied. This may cause the UE to perform handover of only the PCell, or the PSCell accessed by the UE is not the optimal PSCell or the handover fails, thereby causing network performance degradation. The same problem exists in that when the execution condition of the PSCell is satisfied first, the UE still cannot determine a suitable PCell for handover, which may cause the UE to perform only addition or change of the PSCell, or cause the PCell accessed by the UE to be not the optimal PCell or directly cause access failure.

In order to solve the above problem, embodiments of the present application provide a solution, and a core idea thereof is: in a conditional PCell switching scene with PSCell addition or change, an execution condition related to beam information is introduced, namely the network side can additionally configure the execution condition related to the corresponding beam information for the candidate target PCell. When the cell-level execution condition of a certain PCell is satisfied, the UE may further select an optimal PSCell from candidate PSCell cells associated with the PCell according to the execution condition related to the beam information, and initiate access to the PCell cell and the PSCell cell at the same time. The solution is also applicable to the measurement target PSCell, the candidate target PSCell is configured with cell level execution conditions and execution conditions related to extra beam information, and when the PSCell is determined to be added or changed, a proper PCell is selected to be accessed according to the beam information, so that the success rate and the reliability of switching are improved.

It should be noted that, for convenience of subsequent discussion, the embodiments of the present application are mainly described by taking the measurement target cell as the PCell, and of course, a person skilled in the art may know that the technical solution of the embodiments of the present application is not limited to a scenario in which the measurement target cell is the PCell, and may also be applicable to a scenario in which the measurement target cell is the PSCell.

In each embodiment of the present application, the measurement target cell is a PCell or a PSCell; the associated target cell is: aiming at a scene that a measurement target cell is a PCell, the associated target cell is a PSCell; and aiming at the scene that the measurement target cell is the PSCell, the associated target cell is the Pcell.

Aiming at the situation that a measurement target cell is a PCell, a target measurement node is a target MN; and for the PSCell scene of the measurement target cell, the target measurement node is the target SN.

Fig. 1 is a schematic flowchart of a conditional reallocation method provided in an embodiment of the present application, where the method is applied to a network node (e.g., a base station), and as shown in fig. 1, the method includes the following steps:

The measurement target cell may be a PCell or a PSCell, the associated target cell is a PSCell in a scenario in which the measurement target cell is a PCell, and the associated target cell is a PCell in a scenario in which the measurement target cell is a PSCell.

In order to enable the user terminal to select a suitable candidate target PCell and its associated candidate target PSCell, or to enable the user terminal to select a suitable candidate target PSCell and its associated candidate target PCell, the network node may send a reconfiguration message including one or more conditional reconfiguration information and assistance information for determining a beam to the user terminal. The condition reconfiguration information at least comprises configuration information of a measurement target cell, configuration information of an associated target cell, cell-level execution conditions of the measurement target cell and beam information related execution conditions.

After receiving the reconfiguration message and the auxiliary information for determining the beam, the user terminal may perform measurement evaluation on a candidate measurement target cell based on a cell-level execution condition of the measurement target cell, and when the measurement evaluation finds that the cell-level execution condition of a certain candidate measurement target cell is satisfied, the user terminal may determine that the candidate measurement target cell is an access measurement target cell.

After determining the access measurement target cell, the user terminal may determine an associated target cell corresponding to the access measurement target cell based on the execution condition related to the beam information and the assistance information for determining the beam, and access the determined access measurement target cell and the determined associated target cell.

Optionally, the auxiliary information for determining the beam may be sent by the network node to the user terminal in various ways, for example, may be included in the conditional reconfiguration information, or may be sent to the user terminal through a broadcast message or dedicated signaling (i.e., sent before or along with the conditional reconfiguration). When the auxiliary information for determining the beam is included in the conditional reconfiguration information and is sent to the user terminal, the auxiliary information for determining the beam may be included in the execution condition related to the beam information in the conditional reconfiguration information or may be included in addition to the execution condition related to the beam information in the conditional reconfiguration information.

According to the condition reconfiguration method provided by the embodiment of the application, the network node can send the reconfiguration message containing the execution conditions related to the beam information to the user terminal and the auxiliary information for determining the beam, so that the user terminal can be assisted to determine the appropriate access measurement target cell and the associated target cell, and the success rate and the reliability of switching are improved.

specifically, the conditional reconfiguration configuration information may include configuration information of a measurement target cell and configuration information of an associated target cell, an execution condition at a cell level of the measurement target cell, and an execution condition related to beam information corresponding to the associated target cell, taking the measurement target cell as a PCell as an example, for a candidate target PCell 1 corresponding to a plurality of candidate target pscells (e.g., PSCell1, PSCell 2, and PSCell 3), one conditional reconfiguration configuration information may include configuration information of PCell 1 and configuration information of PSCell1, an execution condition at a cell level of PCell 1, and an execution condition related to beam information corresponding to PSCell1, and another conditional reconfiguration configuration information may include configuration information of PCell 1 and configuration information of PSCell 2, an execution condition at a cell level of PCell 1, and an execution condition related to beam information corresponding to PSCell 2, and another conditional reconfiguration configuration information may include configuration information of PCell 1 and configuration information of PSCell 3, and beam information corresponding to PSCell 3.

specifically, the conditional reconfiguration information may include configuration information of one measurement target cell, configuration information of at least one associated target cell, a cell-level execution condition of the measurement target cell, and an execution condition related to beam information corresponding to each associated target cell. Taking the measurement target cell as the PCell as an example, for a candidate target PCell 1, which corresponds to a plurality of candidate target pscells (such as PSCell1, PSCell 2, and PSCell 3), for example, one condition reconfiguration configuration information may include configuration information of the PCell 1, configuration information of the PSCell1, PSCell 2, and PSCell 3, an execution condition of a cell level of the PCell 1, and an execution condition related to beam information corresponding to the PSCell1, PSCell 2, and PSCell 3.

Step 1, a target MN side acquires a candidate target PSCell cell determined by a target SN side and PSCell addition or change configuration information generated by the candidate target PSCell cell.

And 2, the target MN side selects a candidate target PCell cell from the PCell cells recommended by the source MN side.

Step 2-1, aiming at the condition that the switching configuration information of the PCell comprises configuration information added or changed by one PSCell: for each candidate target PCell cell, the target MN side generates PCell handover configuration information for it that includes configuration information for only one candidate target PSCell cell.

Step 2-2, aiming at the condition that the switching configuration information of the PCell comprises configuration information added or changed by a plurality of PSCells: for each candidate target PCell cell, the target MN side generates PCell handover configuration information for it, including configuration information of all candidate target PSCell cells received from the target SN side. The PSCell may be the same Cell group or may be different.

And 3, the target MN side transmits the generated switching configuration information of the PCell containing the configuration information added or changed by one or more PSCells to the source MN side.

And step 4, the UE receives the RRC reconfiguration message with one or more pieces of conditional reconfiguration information, and acquires the cell-level execution condition contained in each piece of conditional reconfiguration information and the execution condition related to the beam information.

And step 5, the UE starts to measure and evaluate the candidate PCell cell and the associated candidate PSCell cell based on the cell-level execution condition.

Step 6, optionally, corresponding to step 4, the ue acquires the auxiliary information for determining the beam through a dedicated signaling; or the UE acquires the auxiliary information for determining the beam from the system message (steps 6 and 7 do not distinguish the order).
