    Abstract: A method for managing an extended Discontinuous Reception (eDRX) in a User Equipment (UE) including determining, by the UE, as to whether an eDRX enablement avoidance criterion is met, and causing, by the UE, to stop sending a request message, which is configured to enable the eDRX, to a network entity when the eDRX enablement avoidance criterion is met. The eDRX enablement avoidance criterion may include one of a data transmission pattern, a historic eDRX usage pattern, whether a configurable retry timer is deactivated, whether a number attempts made to enable the eDRX exceeds a threshold, whether a number of attempts made to enable and disable the eDRX exceeds a threshold, whether a request accept message including an indication that eDRX is not supported, is received from the network entity, or whether an indication of no eDRX support is received from the network entity may be provided.

    Abstract: The present disclosure relates to a technology for a sensor network, a machine-to-machine (M2M) communication, machine type communication (MTC), and the Internet of things (IoT). The present disclosure can be utilized for the intelligent service (a smart home, a smart building, a smart city, a smart car or a connected car, healthcare, digital education, a retail business, a security and safety-related service or the like) on the basis of the technology. Embodiments of the present invention provide a device and a method for minimizing an overhead of a mobile communication network in a machine type communication (MTC) system and minimizing power consumption in devices for MTC. According to an embodiment of the present invention, a base station device of a mobile communication network for M2M communication comprises: a transceiver for transmitting and receiving a signal to/from a leader device among a plurality of devices for M2M communication; and a control unit for transmitting, to the reader device, a downlink control signal through the transceiver in at least one predetermined interval within a scheduling interval and receiving, from the reader device, an uplink signal through the transceiver at a specific time point determined from the predetermined interval within the scheduling interval.

    Abstract: A dormant/idle mode operation of a plurality of cellular device(s) is offloaded using proximity radio interface to a second device having cellular capability so that a plurality of cellular devices can turn off the radio and baseband circuitry associated with the cellular capability, and save battery power. The second device to which the dormant/idle mode operation is offloaded acts like a proxy device for a plurality of cellular devices to perform at least one of the following functions on behalf of plurality of cellular devices: monitor network page, perform cell re-selection, perform tracking area update, or perform D2D transmission and reception, wherein the second device and the plurality of cellular devices are connected each other through a proximity radio interface.

    Abstract: A method and system for providing small cell deployment and access in a green 3GPP LTE system are disclosed. The method includes establishing, by a UE, an RRC connection with a macro cell, receiving, by the macro cell, an RRC connection establishment message from the UE, wherein the RRC connection establishment message includes an IE including an identity of a list of small cells on which the UE can initiate a connection, determining by the macro cell, at least one small cell for data transfer, verifying, by the macro, if the at least one small cell is in a sleep mode or not, triggering, by the macro cell, a connection setup message for initiating a connection between the UE and the at least one small cell if the small cell is in a wake up mode, sending, by the UE, an SRS for initial timing alignment and allocating by the at least one small cell, an uplink/downlink resource to the UE for communication with the at least one small cell.
