摘要:
A Power Headroom Report (PHR) method and apparatus for a mobile communication system supporting carrier aggregation are provided. The method for transmitting PHR of a terminal in a mobile communication system includes configuring, when a PHR is triggered for at least one activated serving cell, an extended PHR for the at least one activated serving cell, the PHR being triggered when a change of a downlink path loss in the at least one activated serving cell is greater than a predetermined threshold value, and transmitting the extended PHR.

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.

To solve the above-mentioned problem, a method in which a terminal reports channel state information comprises the following steps: receiving, from a base station, information on a plurality of patterns to be used in a channel state measurement; receiving, from the base station, selection information for selecting a pattern from among the plurality of patterns that is to be used in the channel state information to be reported to the base station; measuring a channel state using the information on the plurality of patterns; and selecting a portion of the measured channel state based on the selection information, and reporting the selected portion to the base station. The above-described solution enables the efficient reporting of channel state information including CQIICSI, thus improving communication efficiency.

The present invention proposes a method for activating secondary carriers in addition to the primary carrier in a wireless communication system supporting carrier aggregation technology. Through the present invention, the UE sorts the operations for activating an SCell into two groups that are executed at different timings, thereby facilitating communication without malfunctioning.

A method and apparatus for reporting Power Headroom (PH) of a User Equipment (UE) per carrier efficiently in a mobile communication system supporting carrier aggregation are provided. The method includes calculating PHs for multiple activated carriers based on whether data channel transmission takes place on each carrier, configuring indicators indicating whether the data channel transmission takes place on the corresponding carriers, and transmitting the PHs and indicators as aggregated in an extended PH Report (PHR) on one of the carriers.

A method and apparatus for determining a maximum transmission power per carrier in a mobile communication system supporting carrier aggregation are provided. The method for determining the maximum transmission power of a terminal in a mobile communication system supporting carrier aggregation includes checking whether a data channel transmission occurs on each of a plurality of carriers of which Power Headrooms (PHs) are reported in an extended PH Report (PHR), and determining the maximum transmission power of each carrier of the plurality of carriers in consideration of whether the data channel transmission occurs on a carrier corresponding to the data channel transmission.
