Abstract
A cell search method for a terminal capable of cell search control includes: receiving a message including first cell search information from a macro cell base station that manages a macro cell; updating second cell search information stored in the terminal based on the first cell search information; and searching for an accessible cell based on the updated second cell search information.
Claims17
A method for a mobile device terminal to control cell search, the method comprising:
- receiving a message including first cell search information from a macro cell base station that manages a macro cell;
- updating second cell search information stored in the terminal based on the first cell search information;
- searching for an accessible cell based on the updated second cell search information,
- wherein the receiving of the message comprises receiving a paging message,
- wherein the receiving of the paging message comprises:
- detecting and receiving a physical downlink control channel signal while the terminal maintains an idle state;
- determining whether the physical downlink control channel signal corresponds to the terminal by comparing a cell ID in the physical downlink channel signal with a home cell ID of the terminal;
- and
- when the physical downlink control channel corresponds to the terminal, demodulating a physical downlink shared channel.

A mobile device terminal comprising:
- a receiving unit for receiving a message including first cell search information from a macro cell base station that manages a macro cell;
- a processing unit for updating second cell search information that the terminal stores based on the first cell search information;
- and
- a searching unit for searching for an accessible cell based on the updated second cell search information,
- wherein the processing unit updates a cell ID,
- wherein the processing unit activates a first cell ID when the first cell ID included in a first cell search list is included in a second cell search list and deactivates a second cell ID when the second cell ID included in the first cell search list is not included in the second search list.
