Patent ID: 8908583

Claim:
A method of allocating resources in a wireless communication system, comprising: entering, by a wireless device, into a base station by performing a downlink channel scanning and an uplink channel scanning, a synchronization with the base station, and a procedure of calculating a transmission parameter for a downlink channel and an uplink channel; generating, by the wireless device, a persistent service flow through a dynamic service addition (DSA) procedure, wherein the DSA procedure is performed by communicating a DSA request message and a DSA response message between the wireless device and the base station, wherein at least one of the DSA request message or the DSA response message includes a first parameter indicating whether at least one of the wireless device or the base station support a persistent scheduling allocation, wherein at least one of the DSA request message or the DSA response message includes a second parameter indicating whether at least one of the wireless device or the base station supports an autonomous allocation and deallocation for the resources allocated by the persistent scheduling allocation, and wherein the second parameter is represented by a bitmap format; receiving, by the wireless device from the base station, an allocation message for allocating persistent scheduling resources used in persistent scheduling, the wireless device making a transition between Low Power Consumption (LPC) mode and active mode; communicating with the base station, by the wireless device, using the persistent scheduling resources, for active duration in which the wireless device operates in the active mode; and deallocating the persistent scheduling resources automatically when the active duration is finished, wherein the wireless device is a Machine Type Communication (MTC) device for MTC.
