Abstract
A technology related to a terminal apparatus, a communication method, and an integrated circuit is provided for efficiently monitoring a status of communication. The terminal apparatus communicates with the base station apparatus by switching between a first frequency and a second frequency in a cell, a timer for monitoring a radio link in the cell starts based on consecutively detecting that out of synchronization occurs a prescribed number of times, the timer stops in the case of switching between the first frequency and the second frequency, and any one of the first frequency and the second frequency is a frequency by which the terminal apparatus has established Radio Resource Control connection.
Claims13
A terminal apparatus for communicating with a base station apparatus via a cell,
- the terminal apparatus communicating with the base station apparatus by switching between a first frequency and a second frequency different from the first frequency in the same cell,
- wherein a timer for monitoring a radio link in the cell is common between the first frequency and the second frequency,
- the timer starts based on consecutively detecting that out of synchronization (out-of-sync) occurs a prescribed number of times,
- the timer stops in the case of switching between the first frequency and the second frequency, and
- any one of the first frequency and the second frequency is a frequency by which the terminal apparatus has established Radio Resource Control (RRC) connection on the same cell.
A terminal apparatus for communicating with a base station apparatus via a cell,
- the terminal apparatus communicating with the base station apparatus by switching between a third frequency and a fourth frequency different from the third frequency in the same cell,
- wherein, in a case of monitoring a radio link in the cell, detection for out of synchronization (out-of-sync) is performed only by any one of the third frequency and the fourth frequency, and
- any one of the third frequency and the fourth frequency is a frequency by which the terminal apparatus has established Radio Resource Control (RRC) connection on the same cell.
A communication method to be applied to a terminal apparatus for communicating with a base station apparatus via a cell, the method comprising at least the step of:
- communicating with the base station apparatus by switching between a first frequency and a second frequency different from the first frequency in the same cell,
