1. A wireless communication method, applied to a user equipment, comprising:
acquiring at least one candidate cell resource configuration, wherein the at least one candidate cell resource configuration is configured by a target node based on at least one triggering condition;
in a case that the at least one triggering condition has a satisfied triggering condition, determining a candidate cell resource configuration associated with a target triggering condition in the satisfied triggering condition as a target cell resource configuration; and
initiating a communication process associated with the target triggering condition, based on the target 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 there exist a plurality of satisfied triggering conditions, prior to the determining the candidate cell resource configuration associated with the target triggering condition in the satisfied triggering condition as the target cell resource configuration, the method further comprises:
selecting the target triggering condition from the satisfied triggering conditions according to preset triggering condition priorities.
