Terminal device, base station device, measurement method, and integrated circuit
Provided is a technology related to a terminal device, a base station device, a communication system, a measurement method and an integrated circuit that efficiently perform cell measurement. The base station device configures a primary cell and one or more secondary cells to the terminal device, and indicates a measurement object, a reporting configuration including information indicating a threshold associated with an RSSI report and a report interval, and a measurement identity for linking the reporting configuration and the measurement object, to the terminal device. When, in each configured measurement identity, an associated reporting configuration includes information indicating the threshold associated with the RSSI report and the report interval, the terminal device periodically reports an average value of RSSIs measured in a duration of the report interval, and a percentage of the RSSIs being beyond the threshold as a measurement result.
1. A terminal device
configured to:
configure a primary cell and one or more secondary cells, and
in a case where, with respect to each configured measurement identity, a reporting configuration, which is associated with the each configured measurement identity, includes information indicating a threshold associated with a Received Signal Strength Indicator (RSSI) report and a report interval, periodically report, as a measurement result, (i) an average value of RSSIs measured in a duration of the report interval and (ii) a percentage of the RSSIs being beyond the threshold.
2. A base station device
configured to:
configure a primary cell and one or more secondary cells to a terminal device; and
indicate (i) a measurement object, (ii) a reporting configuration including information indicating a threshold associated with a Received Signal Strength Indicator (RSSI) report and a report interval, and (iii) a measurement identity for linking the reporting configuration and the measurement object, to the terminal device to cause the terminal device to periodically report, as a measurement result, (i) an average value of RSSIs of a frequency indicated by the measurement object in a duration of the report interval and (ii) a percentage of the RSSIs being beyond the threshold.
3. A measurement method of a terminal device comprising at least the steps of:
configuring a primary cell and one or more secondary cells; and
in a case where, with respect to each configured measurement identity, a reporting configuration, which is associated with the each configured measurement identity, includes information indicating a threshold associated with a Received Signal Strength Indicator (RSSI) report and a report interval, periodically reporting, as a measurement result, (i) an average value of RSSIs measured in a duration of the report interval and (ii) a percentage of the RSSIs being beyond the threshold.
