Abstract
Received Signal Strength Indicator (RSSI) is measured accurately even in a case where a discovery signal is transmitted. A receiver receives a plurality of subframes, at least one of which includes a discovery signal, and a measurer measures Reference Signal Reception Power (RSRP) using a first resource in which the discovery signal is mapped, measures RSSI using a second resource different from the first resource for which the discovery signal is mapped, and calculates Reference Signal Reception Quality (RSRQ) using RSRP and RSSI.
Claims12
A communication apparatus comprising:
- a receiver which, in operation, receives discovery signal information indicating subframes in which discovery signals are transmitted;
- and
- a measurement circuitry which, in operation, measures Reference Signal Reception Power (RSRP) and Received Signal Strength Indicator (RSSI) for Reference Signal Reception Quality (RSRQ) by using only the subframes in which the discovery signals are transmitted,
- wherein a number of first resource elements used for measuring the RSSI within the subframes is larger than a number of second resource elements used for measuring the RSRP.
A reception quality measurement method comprising:
- receiving discovery signal information indicating subframes in which discovery signals are transmitted;
- and
- measuring Reference Signal Reception Power (RSRP) and Received Signal Strength Indicator (RSSI) for Reference Signal Reception Quality(RSRQ) by, using only the subframes in which the discovery signals are transmitted,
- wherein a number of first resource elements used for measuring the RSSI within the subframes is larger than a number of second resource elements used for measuring than the RSRP.
