Patent ID: 11064554

Abstract:
To provide a radio communication device and a radio communication method that can surely avoid a state that communication cannot be started because of a disagreement in states in an intermediate layer, which is lower to RRC layer, when transitioning between a connected state (RRC-Connected) and a suspended state (RRC-Suspended) in the RRC layer. UE (100) includes a state controlling unit (120) that controls the RRC layer to be in the connected state or the suspended state, and an interruption processing unit (130) that initializes at least a part of states in the intermediate layer, specifically MAC layer/RLC layer/PDCP layer, after the RRC layer has transitioned from the connected state to the suspended state. The state controlling unit (120) causes the RRC layer to resume from the suspended state to the connected state based on the state of the intermediate layer initialized by the interruption processing unit (130).
