Wireless communication method, source node and target node

A wireless communication method, applied to a source node, comprising:

• receiving at least one candidate cell resource configuration sent by a target node, wherein the at least one candidate cell resource configuration is configured by the target node based on at least one triggering condition, the at least one candidate cell resource configuration is configured to, in a case that a user equipment determines that the at least one triggering condition has a satisfied triggering condition, enable the user equipment to determine a candidate cell resource configuration associated with a target triggering condition in the satisfied triggering condition as a target cell resource configuration and initiate, based on the target cell resource configuration, a communication process associated with the target triggering condition;
• and
• sending a radio resource control (RRC) reconfiguration message to a user equipment, wherein the RRC reconfiguration message comprises the at least one candidate cell resource configuration;
• wherein the at least one triggering condition corresponds to service requirements, and the at least one triggering condition comprises one or more of:
• a data packet transmission delay is greater than or equal to a first preset threshold;
• a packet loss rate of data packet is greater than or equal to a second preset threshold;
• a data transmission rate is greater than or equal to a third preset threshold;
• or
• a secondary cell group (SCG) access failure;
• wherein the communication process associated with the target triggering condition comprises one of:
• in a case that the data transmission rate is greater than or equal to the third preset threshold, initiating a secondary node (SN) Addition process for the target node;
• in a case that the data packet transmission delay is greater than or equal to the first preset threshold, initiating an SN Modification process for a source node;
• or
• in a case of a secondary cell group (SCG) access failure, initiating an SN Change process for the target node;
• wherein the at least one triggering condition is agreed by an agreement, and the method further comprises:
• sending a handover request sent to the target node, wherein the handover request contains 1 bit to indicate that the handover request is a condition-based handover request.
