Abstract

The present invention relates to a method and a device for machine type communication in a wireless communication system, and according to one embodiment of the present invention, a method for receiving a paging message in a wireless communication system for supporting MTC comprises the steps of: determining whether there is a terminal within a normal coverage (NC) or an extended coverage (EC), transmitting, to a network, state information including EC function support information and/or area display information of the NC or the EC according to the determination result; determining a paging receiving time according to an operation mode related to the state information, and receiving the paging message according to the determined paging receiving time.

Claims

1. A method performed by a terminal in a wireless communication system, the method comprising:

receiving configuration information related to a cell reselection from a base station;

applying a cell reselection rule based on the configuration information related to the cell reselection;

performing intra-frequency measurement or inter-frequency measurement based on a result of the applying and a timer for an enhanced coverage in case that the terminal is in the enhanced coverage;

identifying a cell reselection criterion based on the performed measurement; and

performing the cell reselection based on the identified cell reselection criterion, irrespective of configured frequency priorities while the terminal is in the enhanced coverage.

2. The method of claim 1, wherein the timer for the enhanced coverage starts or re-starts based on the terminal being camped on a base station in the enhanced coverage or the intra-frequency measurement or the inter-frequency measurement being performed.

3. The method of claim 1, wherein, while the terminal is in the enhanced coverage, the terminal regards the configured frequency priorities as same as one another.

4. A terminal in a wireless communication system, the terminal comprising:

a transceiver; and

a controller,

configured to;

receive, from a base station via the transceiver, configuration information related to a cell reselection,

apply a cell reselection rule based on the configuration information related to the cell reselection,

perform intra-frequency measurement or inter-frequency measurement based on a result of the applying and a timer for an enhanced coverage in case that the terminal is in the enhanced coverage,

identify a cell reselection criterion based on the performed measurement, and

perform the cell reselection based on the identified cell reselection criterion, irrespective of configured frequency priorities while the terminal is in the enhanced coverage.

5. The terminal of claim 4, wherein the timer for the enhanced coverage starts or re-starts based on the terminal being camped on a base station in the enhanced coverage or the intra-frequency measurement or the inter-frequency measurement being performed.

6. The terminal of claim 4, wherein, while the terminal is in the enhanced coverage, the terminal regards the configured frequency priorities as same as one another.
