Method and apparatus for reselecting a cell in heterogeneous networks in a wireless communication system
First Claim
1. A method for inter radio access technology (RAT) cell reselection by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, system information including information for inter RAT cell reselection;
determining whether the system information includes a quality value for cell reselection;
determining whether a terminal supports a quality value based cell reselection if the system information includes the quality value for the cell reselection;
performing a first cell reselection based on the quality value if the terminal supports the quality value based on the cell reselection; and
performing a second cell reselection based on a reception level value if the terminal does not support the quality value based cell reselection.

Abstract
The present disclosure provides a method for cell reselection in a wireless communication system in which various radio access technologies (RATs) coexist with each other. In a wireless communication system in which heterogeneous networks coexist with each other, the method of cell reselection between heterogeneous networks for a user equipment may include: receiving a system information block (SIB) containing cell reselection parameters from a corresponding base station; checking whether cell reselection parameters based on a cell selection quality value (Squal) are configured in the received SIB; and performing, when cell reselection parameter based on Squal are not configured, cell reselection based on a cell selection receive level value (Srxlev). The present disclosure may prevent the user equipment from performing unnecessary cell reselection.

6. A terminal for performing cell reselection, the terminal comprising:
-
a transceiver configured to transmit and receive a signal; and at least one processor configured to; control the transceiver to receive, from a base station, system information including information for inter radio access technology (RAT) cell reselection, determine whether the system information includes a quality value for cell reselection, determine whether a terminal supports a quality value based cell reselection if the system information includes the quality value for the cell reselection, perform a first cell reselection based on the quality value if the terminal supports the quality value based cell reselection, and perform a second cell reselection based on a reception level value if the terminal does not support the quality value based cell reselection. - View Dependent Claims (7, 8, 9, 10)
