Abstract

The invention discloses a method and an apparatus in a communication node used for wireless communication. The communication node receives the first signaling; the first signaling is used for determining a first measurement configuration set, and the first measurement configuration set is associated with a first index; receiving a second signaling, the second signaling being used for determining a first condition configuration set, the first condition configuration set comprising the first index; when the first condition configuration set originates from a first entity, performing measurement according to the first measurement configuration set; when the first set of condition configurations originates from a second entity, measurements are performed according to a second set of measurement configurations. According to the invention, the MN and the SN can be supported to perform CPC configuration at the same time.

Description

technical field [0001] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular, to a multi-connection transmission method and apparatus. Background technique [0002] During the formulation process of Release 16 of the 3GPP (the 3rd Generation Partnership Project), mobility enhancements on NR (New Radio, new air interface) and LTE (Long Term Evolution, long-term evolution) have been completed. Reduce data transfer interruptions during handovers and improve handover robustness. Condition-based PSCell (Primary SCG Cell, primary and secondary cell) is discussed in the work items (Work Item, WI) of eDCCA (enhanced Dual Connection and Carrier Aggregation) and Mobility Enhancement (Mobility Enhancement). Addition / Change (Conditional PSCell Addition / Change, CPAC), but not completed due to time constraints. The 86th RAN meeting passed the "further enhancement of MR-DC (Multi-Radio Dual-Connectivity, Multi-Radio D...
