摘要:
The present invention relates to a method and to an apparatus for optimizing the power consumption of a terminal in a mobile communication system. The method for optimizing power consumption of a terminal in a mobile communication system comprises: a determination step of determining whether there is a need for changing a configuration for a discontinuous reception operation of the terminal; and a transmission step of transmitting, to a base station, a request message for a change in the discontinuous reception operation, if it is determined that the change is needed.

The present invention relates to a method and a device for cell activation in a carrier aggregation system, and the method for activating a cell of a terminal according to one embodiment of the present invention comprises: a step for receiving an activation message of a first cell; a step for activating the first cell when the message of the first cell is received; an information obtaining step for obtaining uplink activation information of the first cell; and a transmission determination step for determining whether to execute an uplink transmission according to the uplink activation information. According to an embodiment of the present invention, efficient carrier management plan can be provided.

A method and terminal apparatus for transmitting a status report comprising a received status of packet data in a mobile communication system are provided, in which whether transmission of an implicit Negative Acknowledge (NACK) signal is required for requesting retransmission of at least one non-received data packet whose sequence number is unidentified is determined, if transmission of the implicit NACK signal is required, the implicit NACK signal including a sequence number of the last packet is generated among successfully received data packets, and a status report including the implicit NACK signal is transmitted to the transmitter, and if transmission of the implicit NACK signal is not required, a status report is transmitted to the transmitter including at least one of an ACK signal comprising a sequence number of a successfully received data packet and an explicit NACK signal comprising a sequence number of a non-received data packet whose sequence number is identified.

The present invention defines an efficient contention-based access procedure in a mobile communication system. The present invention is directed to a 3GPP LTE/LTE-A mobile communication system under discussion in the 3GPP as one of the representative next generation mobile communication system.
摘要:
A method and a UE apparatus for radio resource management in a mobile communication system. When a discontinuous reception period or an inactivity period of a UE exceeds a threshold, an ENB releases resources for uplink control information transmission allocated to the UE, and the UE recognizes the release of the resources and stops transmitting the uplink control information through the resources. This reduces the explicit reconfiguration procedure through an RRC message, which is otherwise necessary whenever the UE enters a new discontinuous reception mode.

Methods and apparatus are provided for reporting a Power Headroom (PH) of a User Equipment (UE) in a wireless communication system having a plurality of aggregated uplink carriers. The PH is calculated for a Power Headroom Report (PHR)-triggered uplink carrier. A PHR having the PH and an identifier of the PHR-triggered uplink carrier is generated, and the PHR is transmitted to a network. Also, a PHR having the PH is generated, and the PHR is transmitted to a network over one of a plurality of PHR-transmitting uplink carriers configured to correspond to the PHR-triggered uplink carrier.
摘要:
A method for receiving a packet by a terminal in a mobile communication system including a base station providing a packet, and a terminal that discontinuously receives a packet from the base station in Discontinuous Reception (DRX) cycles each having an active period and a sleep period. The packet reception method includes receiving, from the base station, configuration information for a DRX service, including a DRX cycle length; setting, as a starting point of the DRX cycle, a point at which a first packet is received from the base station; receiving a packet from the base station for an active period at the beginning of the starting point; and transitioning to a sleep period and waiting for a next active period.
摘要:
A method and apparatus for detecting contention in an RA procedure in a mobile communication system is provided in which an L2/L3 message is received from a UE in uplink resources allocated to the UE by an RA preamble response message that was transmitted for an RA procedure initiated by the UE, a CR message associated the RA procedure is transmitted to the UE, if the L2/L3 message is an initial access message, and predetermined control information is transmitted to the UE on a downlink control channel without transmitting the CR message, if the L2/L3 message is not an initial access message.
摘要:
An apparatus and method for performing cell selection to a Home cell or a Private network in a mobile communication system are provided, in which a User Equipment (UE) determines a candidate cell by measuring a serving cell and neighbor cells, receives an indicator indicating a Home cell or a Private network in system information from the candidate cell, determines whether the candidate cell is included in a Home cell or Private network list set in the UE, and selects the candidate cell if the candidate cell is included in the Home cell or Private network list.
摘要:
A retransmission method and apparatus performed in a transmitter of a mobile communication system supporting a Hybrid Automatic Retransmission reQuest (HARQ) operation and an Automatic Retransmission request (ARQ) operation for retransmission of a packet are provided. At least one ARQ entity generates at least one ARQ packet, and an HARQ entity transmits an HARQ packet including the at least one ARQ packet to a receiver, and transmits a local NACK signal indicating transmission fail of the ARQ packet to a corresponding ARQ entity, if the HARQ packet fails in transmission.
