Abstract
A radio terminal (3) operates to perform a predetermined process regarding a first cell (Cell #2) on an unlicensed frequency (F2) based on a predetermined relationship between a frame timing of a first serving cell (Cell #1) using a licensed frequency (F1) and a frame timing of the first cell (Cell #2) using the unlicensed frequency (F2). This contributes, for example, to enabling a radio terminal to differentiate among two or more cells when these cells use the same cell identifier.

1-46. (canceled)
A radio terminal configured to perform Licensed Assisted Access (LAA) using a primary cell operating in licensed frequency and a secondary cell operating in unlicensed frequency, the radio terminal comprising:
- a transceiver;
- and
- a processor configured to:
- receive, via the transceiver, an offset value to indicate subframe of the secondary cell,
- detect the secondary cell operating in the unlicensed frequency based on:
- subframe timing of the secondary cell, the subframe timing of the secondary cell being aligned with subframe timing of the primary cell, and
- the offset value to indicate the subframe of the secondary cell, and
- measure RSRP and RSRQ of one or more discovery signals transmitted on the detected secondary cell based on:
- the subframe timing of the secondary cell, and
- the offset value to indicate the subframe of the secondary cell.
A method for a radio terminal configured to perform Licensed Assisted Access (LAA) using a primary cell operating in licensed frequency and a secondary cell operating in unlicensed frequency, the method comprising:
- receiving an offset value to indicate subframe of the secondary cell,
- detecting the secondary cell operating in the unlicensed frequency based on:
- subframe timing of the secondary cell, the subframe timing of the secondary cell being aligned with subframe timing of the primary cell, and
- the offset value to indicate the subframe of the secondary cell, and
- measure RSRP and RSRQ of one or more discovery signals transmitted on the detected secondary cell based on:
- the subframe timing of the secondary cell, and
- the offset value to indicate the subframe of the secondary cell.
