Abstract
A method for reducing power consumption of a macro Base Station (BS) in a radio communication system is provided. The method includes transmitting a preamble through at least one mini BS installed within a service coverage area of the macro BS, and transmitting a power-off command to the at least one mini BS after being switched into a power-on state, upon reception of access request information through the at least one mini BS from a terminal that received the preamble.
Claims18
A method for reducing power consumption of a macro Base Station (BS) in a radio communication system, the method comprising:
- transmitting a preamble through at least one mini BS installed within a service coverage area of the macro BS;
- and
- transmitting a power-off command to the at least one mini BS after being switched into a power-on state, upon reception of access request information through the at least one mini BS from a terminal that received the preamble.
A method for reducing power consumption of a macro Base Station (BS) in a radio communication system, the method comprising:
- transmitting a preamble upon reception of a power-on command from the macro BS;
- forwarding access request information received from a terminal that received the preamble to the macro BS;
- and
- stopping the transmitting of the preamble upon reception of a command to stop the transmitting of the preamble from the macro BS.
A method for reducing power consumption of a macro Base Station (BS) by a terminal in a radio communication system, the method comprising:
- receiving a preamble that includes indication information and determining an entity that transmits the preamble based on the indication information;
- and
- transmitting access request information to the macro BS, if the entity is not the macro BS, and performing an access procedure with the macro BS upon expiration of an access waiting time.
A macro Base Station (BS) for reducing power consumption in a radio communication system, the macro BS comprising:
- a transceiver configured to transmit a preamble through at least one mini BS installed within a service coverage area of the macro BS;
- and
- a controller configured to control the transceiver to transmit a power-off command to the at least one mini BS, after being switched into a power-on state upon recognition that access request information of a terminal that received the preamble has been received through the at least one mini BS.
A mini Base Station (BS) for reducing power consumption of a macro BS in a radio communication system, the mini BS comprising:
- a transceiver configured to recognize that a power-on command has been received from the macro BS;
- and
- a controller configured to control the transceiver to transmit a preamble, control the transceiver to forward the macro BS access request information received from a terminal that received the preamble, and control the transceiver to stop transmitting the preamble upon recognition that a command to stop the transmitting of the preamble has been received through the transceiver.
A terminal for reducing power consumption of a macro Base Station (BS) by a terminal in a radio communication system, the terminal comprising:
- a transceiver configured to receive a preamble that includes indication information;
- and
- a controller configured to determine an entity that transmits the preamble based on the indication information, control the transceiver to transmit access request information to the macro BS, if the entity is not the macro BS, and perform an access procedure with the macro BS upon expiration of an access waiting time.
