1. A method for operating in an idle mode for Machine To Machine (M2M) communication, comprising:
- entering, by a M2M device, into an idle mode;
receiving, by the M2M device in the idle mode, a paging message from a base station, the paging message includes a M2M group identifier, a network access type, a resource offset and a monitoring duration,the M2M group identifier that identifies a M2M group to which the M2M device belongs,the network access type indicating a resource allocation for a ranging request,the resource offset indicating an offset that the M2M device starts to monitor an uplink resource assignment,the monitoring duration indicating a time duration that the M2M device monitors the uplink resource assignment; and
monitoring, by the M2M device, the uplink resource allocation beginning from the offset during the monitoring duration,wherein a cyclic redundancy check (CRC) of the uplink resource assignment is masked with the 12 least significant bits of a fixed M2M deregristation identifier (FMDID) to decode the uplink resource assignment, andwherein the 4 most significant bits of the FMDID are included in the uplink resource assignment.

Abstract
A method and device for operating in an idle mode for Machine To Machine (M2M) communication are provided. A M2M device receives a paging message from a base station. The paging message includes a M2M group identifier that identifies a M2M group to which the M2M device belongs. The M2M device monitors an uplink resource allocation beginning from an offset during a monitoring duration.

6. A wireless device configured for operating in an idle mode for Machine To Machine (M2M) communication, comprising:
-
a radio frequency unit for receiving and transmitting a radio signal; and a processor operatively coupled with the radio frequency unit and configured to; enter into an idle mode; receive, at the idle mode, a paging message from a base station, the paging message includes a M2M group identifier, a network access type, a resource offset and a monitoring duration, the M2M group identifier that identifies a M2M group to which the wireless device belongs, the network access type indicating a resource allocation for a ranging request, the resource offset indicating an offset that the wireless device starts to monitor an uplink resource assignment, the monitoring duration indicating a time duration that the wireless device monitors the uplink resource assignment; and monitor the uplink resource allocation beginning from the offset during the monitoring duration, wherein a cyclic redundancy check (CRC) of the uplink resource assignment is masked wit the 12 least significant bits of a fixed M2M deregristation identifier (FMDID) to decode the uplink resource assignment, and wherein the 4 most significant bit bits of the FMDID are included in the uplink resource assignment. - View Dependent Claims (7, 8, 9, 10)
