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.
Claims6
A radio terminal comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- perform Licensed Assisted (LAA) using a primary cell operating in licensed frequency and a secondary cell operating in unlicensed frequency, the primary cell and the secondary cell being served by at least one radio station;
- receive, from the at least one radio station, an offset value that is indicated by a number of subframes;
- and
- perform Received Signal Strength Indicator (RSSI) measurements on the unlicensed frequency, based on the offset value and a timing of a first symbol in a subframe of the primary cell.

A radio station comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- provide Licensed Assisted Access (LAA) using a primary cell operating in licensed frequency and a secondary cell operating in unlicensed frequency to a radio terminal, one or both of the primary cell and the secondary cell being served by the radio station;
- transmit, to the radio terminal, an offset value that is indicated by a number of subframes;
- and
- receive, from the radio terminal, a result of Received Signal Strength Indicator (RSSI) measurements on the unlicensed frequency, wherein
- the RSSI measurements is performed by the radio terminal based on the offset value and a timing of a first symbol in a subframe of the primary cell.

- receiving, from the at least one radio station, an offset value that is indicated by a number of subframes;
- and
- performing Received Signal Strength Indicator (RSSI) measurements on the unlicensed frequency, based on the offset value and a timing of a first symbol in a subframe of the primary cell.
