Method and apparatus for controlling operation state of base station in wireless communication system

摘要

Methods and apparatus are provided for controlling transition of an operation state of a cell in a wireless communication system. The cell includes a transceiver configured to transmit and receive signals to and from a terminal and another cell. The cell also includes a controller configured to transition an operation state of the cell from an active state to a dormant state, transmit a discovery signal, determine whether a cell activation signal is received from a node that controls the cell, and transition the operation state of the cell from the dormant state to the active state when the cell activation signal is received.

主权项

1. A method for activating a cell, by the cell, in a wireless communication system, the method comprising the steps of
transitioning an operation state of the cell from an active state to a dormant state; transmitting a discovery signal including cell state information indicating that the operation state of the cell is the active state or the dormant state; determining whether a cell activation signal is received from a node that controls the cell; and transitioning the operation state of the cell from the dormant state to the active state, if the cell activation signal is received.
