Light connection method and apparatus for use in wireless communication system

The present disclosure presents a method performed by a user equipment (UE) and a base station in a wireless communication system. The method executed by the UE comprises the following steps: receiving a first radio resource control (RRC) message associated with RRC release, wherein the first RRC message comprises information associated with a recovery identifier; after the first RRC message is received, sending a random access lead code to the base station; receiving, from the base station, a random access response as a response to the transmission of the random access preamble; and transmitting a second RRC message associated with an RRC recovery request to the base station based on the random access response, the second RRC message including one of a complete recovery identifier or a short recovery identifier, in which system information received from the base station indicates which of the complete recovery identifier and the short recovery identifier is to be used for the RRC recovery request. 本公开提出了由无线通
