The present invention relates to a method and an apparatus for supporting handover and, more particularly, to a method and an apparatus for adjusting handover related parameters. In order to achieve the above-described objective, a method for supporting handover by a base station in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: transmitting a handover parameter to a terminal, based on a handover purpose; receiving, from the terminal, a handover measurement report based on the handover parameter; storing information for the handover purpose; and transmitting, to a target base station, a handover request message including the information for the handover purpose.

Method and apparatus for supporting handover in wireless communication system

Technology for a wireless multi-hop network is provided. A method by which a source node operates in a wireless multi-hop network includes selecting one of first to M-th frame structures (M is a natural number greater than or equal to 2), based on a data packet generation interval, when the source node is in an active state, synchronizing with neighboring nodes in a first synchronization period of the selected frame structure, and when the source node is in the active state, transmitting a control packet to a next hop in a data period of the selected frame structure, and waiting for a response from the next hop, the control packet indicating that the source node will transmit a data packet in a sleep period subsequent to the data period and including information on the selected frame structure. Here, each of the first to M-th frame structures defines a frame including at least one synchronization period, at least one data period, and at least one sleep period, and having a different duty cycle.
