摘要:
Provided are a ranging method in a wireless communication system and a device therefor. A plurality of M2M (machine-to-machine) devices transmit ranging codes, and a base station determines whether a network surge has occurred based on the received ranging codes. When network surge occurs, the base station transmits a network surge indicator and a network surge ranging parameter to a plurality of M2M devices.

Disclosed are M2M equipment and base station capable of adjusting load through a scheduling delay. M2M equipment according to the present invention may comprise a receiver which receives a first message including a scheduling delay indicator directing the M2M equipment to delay transmission of uplink data from a base station, and a processor for controlling transmission of the uplink data to be delayed in response to scheduling delay direction of the first message.

Provided are a method and device for ranging in a wireless communication system. A machine-to-machine (M2M) device receives an advanced air interface-system configuration descriptor (AAI-SCD) message including information on a dedicated ranging channel for the M2M device and an M2M parameter change count from a base station, and attempts ranging through the dedicated ranging channel to the base station. At this point, the M2M parameter change count orders information on the dedicated ranging channel in the AAI-SCD message to change.

A method of allocating resources in a wireless communication system is provided. A wireless device which makes a transition between Low Power Consumption (LPC) mode and active mode receives, from a base station, an allocation message for allocating persistent scheduling resources used in persistent scheduling. The wireless device communicates with the base station using the persistent scheduling resources, for active duration in which the wireless device operates in the active mode. The wireless device deallocates the persistent scheduling resources automatically when the active duration is finished.

Disclosed are an apparatus and method for performing group-based machine to machine (M2M) communication. According to one embodiment of the present invention, a method in which a plurality of M2M communication devices from a group, and a specific M2M communication device which is a member of the group performs communication with a base station, comprises the following steps: transmitting, to the base station, a first message for requesting network registration; receiving, as a response to the first message, a second message containing information on the representative M2M communication device which is a representative of the group; and transmitting, to the representative M2M communication device, data to be transmitted to the base station on the basis of the second message.
