Description

Configuration method, device, terminal and network equipment of candidate cell

Technical Field

The application belongs to the technical field of mobile communication, and particularly relates to a configuration method, a device, a terminal and network side equipment of a candidate cell.

Background

The dual connectivity (Dual Connectivity, DC) technology provides a terminal (also referred to as User Equipment (UE)) with resources of two network nodes, one of which is referred to as a Master Node (MN) and the other as a Secondary Node (SN). At each network node, a carrier aggregation technique (Carrier Aggregation, CA) is used, i.e. a series of serving cells, also called cell groups (cell groups), controlled by the node are configured for the UE. MN controls the primary cell group (MCG, master Cell Group) and SN controls the secondary cell group (SCG, secondary Cell Group). Each Cell group contains one Special Cell (SpCell) and a series of Secondary cells (Scell). The special Cell is called a Primary Cell (PCell) in the MCG, and the special Cell is called a Primary secondary Cell (PSCell, primary Secondary Cell) in the SCG. SpCell uses the primary carrier in one cell group, while other secondary cells use the secondary carrier, and resource scheduling within one cell group is performed by SpCell.

The UE may perform the candidate cell configuration by evaluating the candidate cell and performing a conditional handover (Conditional Handover, CHO) or a conditional primary and secondary cell addition or modification (Conditional PSCell Additional or Change, CPAC) after the execution condition is satisfied, and releasing the candidate cell after the completion, so that the network may perform repeated candidate cell configuration on the UE later, causing unnecessary signaling load.
