摘要： A terminal apparatus executing radio communication with a base station apparatus, the terminal apparatus: transmits a first message, including a random access preamble and identification information of the terminal apparatus, for starting a random access procedure to the base station apparatus; receives a second message, including a random access response to the first message, from the base station apparatus; and selects one random access preamble group from among a plurality of random access preamble groups on the basis of a first condition, a second condition, a third condition, and a status of the terminal apparatus, in order to notify the base station apparatus of the status of the terminal apparatus when transmitting the first message. Consequently, even when a 2-step random access procedure is adopted, radio resources for the radio communication between the base station apparatus and the terminal apparatus can be used efficiently.

摘要： There is provided a terminal including: a reception unit that receives, from a base station, a measurement configuration which associates information indicating an object cell on which given processing is to be performed, with a conditional configuration indicating a condition to initiate the given processing; a measurement unit that measures reception quality of a cell; and a control unit that initiates the given processing corresponding to the conditional configuration when the measured cell is included in the object cell and the reception quality of the measured cell fulfills the condition to initiate the given processing.
