Abstract:
1. A method for performing communication by a machine to machine (M2M) device during a network entry, the method comprising: receiving, by the M2M device from a base station, information on an M2M dedicated ranging resource assigned for an application type of the M2M device, wherein the information on the M2M dedicated ranging resource assigned for the application type of the M2M device includes a cyclic shift offset value of a seed sequence used in generating a ranging code assigned to a human type communication (HTC) device, and wherein the cyclic shift offset value of the seed sequence is different from that of different application type of other M2M device; acquiring the M2M dedicated ranging resource based on the cyclic shift offset value of the seed sequence used in generating the ranging code assigned to the HTC device; and transmitting, by the M2M device, a signal to a base station through the acquired M2M dedicated ranging resource assigned for the application type of the M2M device.
