Abstract
A radio station (1) transmits, to a radio terminal (3) on a licensed frequency (Cell #1), control signaling (S102) associated with at least one of a measurement timing and a measurement period of terminal measurement on an unlicensed frequency (Cell #2) and receives, from the radio terminal (3) on the licensed frequency (Cell #1), a result of the terminal measurement that is executed in response to the control signaling (S102) and in accordance with at least one of the measurement timing and the measurement period (S105). This contributes, for example, to acquisition of information useful for the radio station to determine whether to allow the radio terminal to perform communication on the unlicensed frequency.

A method performed in a radio station, the method comprising:
- communicating with a radio terminal on a licensed frequency;
- transmitting, to the radio terminal on the licensed frequency, control information associated with a discovery signal measurement on an unlicensed frequency,
- wherein the control information includes:
- information indicating periodicity at which a first period, in which a discovery signal can be transmitted, occurs periodically, and
- an offset value to indicate a subframe number and a System Frame Number (SFN) at which the first period starts;
- and
- receiving, from the radio terminal on the licensed frequency, a result of the discovery signal measurement which is performed within the first period which occurs periodically at the periodicity and starts at the subframe number and the SFN indicated by at least the offset value.
A radio station comprising:
- at least one memory that stores instructions;
- and
- at least one processor configured to execute the instructions to:
- transmit, to a radio terminal on a licensed frequency, control information associated with a discovery signal measurement on an unlicensed frequency,
- wherein the control information includes:
- information indicating periodicity at which a first period, in which a discovery signal can be transmitted, occurs periodically, and
- an offset value to indicate a subframe number and a System Frame Number (SFN) at which the first period starts;
- and
- receive, from the radio terminal on the licensed frequency, a result of the discovery signal measurement which is performed within the first period which occurs periodically at the periodicity and starts at the subframe number and the SFN indicated by at least the offset value.
A method for a radio terminal, the method comprising:
- receiving, from a radio station on a licensed frequency, control information associated with a discovery signal measurement on an unlicensed frequency,
- wherein the control information includes:
- information indicating periodicity at which a first period, in which a discovery signal can be transmitted, occurs periodically, and
- an offset value to indicate a subframe number and a System Frame Number (SFN) at which the first period is started;
- performing the discovery signal measurement within the first period which occurs periodically at the periodicity and starts at the subframe number and the SFN indicated by at least the offset value;
- and
- transmitting a result of the discovery signal measurement to the radio station on the licensed frequency.
