Abstract:
1. A method for reducing transmission power consumption in a base station (BS) by adjusting a transmission interval of a control signal, the method comprising: transmitting, by the BS, the control signal at second intervals by changing the transmission interval of the control signal from a first interval into a second interval that is longer than the first interval; receiving a first message including information that requests adjusting of the transmission interval of the control signal; and transmitting the control signal at the first intervals by changing the transmission interval into the first interval, wherein, before changing of the transmission interval of the control signal, the method comprises: transmitting a mode change request message indicating that the BS is to change the transmission interval of the control signal to a core network (CN) that controls the BS; and receiving, from the CN, a response message in response to the message.
