Mobile Communication System, Base Station And Mobile Terminal
Abstract: The present invention has an object to provide a mobile communication system capable of reducing energy consumption of a network node in a local area range. In the present invention, when judging that there is a shift trigger in Step ST1503, a local eNB shifts from a normal operation to an energy saving operation in Step ST1504. In the energy saving operation, the local eNB stops the operation of transmitting at least a part of downlink transmission signals to be transmitted to a user equipment (UE) and performs the operation of receiving an uplink transmission signal transmitted from the UE. When judging that it has received the uplink transmission signal (RACH) in the energy saving operation in Step ST1510, the local eNB shifts to the normal operation in Step ST1511. Figure 15

Specification
We claim:
1. A mobile communication system comprising a base station (72) and a mobile
terminal (71) which can perform radio communication with the base station (72),
wherein the base station (72) turning off a downlink transmission is configured to transmit only measurement signals periodically, and
the mobile terminal (71) is configured to discover the base station (72) turning off the downlink transmission based on the measurement signals.
2. The mobile communication system according to claim 1,
wherein synchronization signals and reference signals are used as the measurement signals.
3. The mobile communication system according to claim 1,
wherein transmission period of the measurement signals is determined by the base station (72) itself.
4. A base station (72) used in a mobile communication system comprising the
base station (72) and a mobile terminal (71) which can perform radio communication
with the base station (72),
wherein the base station (72) turning off a downlink transmission is configured to transmit only measurement signals periodically.
5. A mobile terminal (71) used in a mobile communication system comprising a
base station (72) and the mobile terminal (71) which can perform radio
communication with the base station (72),
wherein the mobile terminal (71) is configured to receive measurement signals transmitted periodically by the base station (72) turning off a downlink transmission, and
the mobile terminal (71) is configured to discover the base station (72) turning off the downlink transmission based on the measurement signals.
