Abstract

One embodiment of the specification provides a cell reselection method of a terminal. The cell reselection method comprises the steps of: receiving, from a serving cell, a common parameter to be used for a cell selecting procedure and a category-specific parameter; measuring the serving cell and / or a neighboring cell; and determining whether the measurement result value satisfies cell selection criteria. At this point, if the terminal is set to use the category-specific parameter, cell reselection can be evaluated by reflecting the category-specific parameter in the measurement result value.

Description

technical field [0001] The present invention relates to wireless communication, and more specifically, relates to a cell selection method and a measurement method for cell reselection. Background technique [0002] 3GPP (3rd Generation Partnership Project) LTE (Long Term Evolution), which is an improvement of UMTS (Universal Mobile Telecommunications System), has been introduced as 3GPP Release 8. 3GPP LTE uses OFDMA (Orthogonal Frequency Division Multiple Access) in the downlink , using SC-FDMA (Single Carrier-Frequency Division Multiple Access) in the uplink. 3GPP LTE employs MIMO (Multiple Input Multiple Output) with up to four antennas. Recently, 3GPP LTE-A (LTE-Advanced), which is an evolution of 3GPP LTE, is being discussed. [0003] In addition, in the 3GPP system, handover refers to a process of transferring a user equipment communicating in a current cell to another cell, and cell reselection refers to a process of transferring a user equipment in an idle state in...
