摘要:
The present invention relates to a method in which a terminal carries out channel quality measurement in a power-efficient fashion in a mobile communication system in which carrier aggregation is employed. If the terminal supports measurement based on serving cell quality, then an additional judgment is made as to whether the terminal is configured for simultaneous communication with a plurality of serving cells and, if the terminal does support measurement based on serving cell quality and is configured for simultaneous communication with a plurality of serving cells, then a decision is made as to whether the quality-representing value for the plurality of serving cells is at or above a threshold value and, if the quality-representing value for the plurality of serving cells is at or above the threshold value, then a quality measurement is carried out within a limited range taking into account the plurality of serving cells.

A method and apparatus of reporting a power headroom in a wireless communication system is provided. A user equipment determines a power headroom based on a configured transmit power and transmits a power headroom report to a base station. The power headroom report includes a power headroom level indicating the power headroom and a backoff indicator indicating whether the user equipment applies power backoff due to power management.

The present invention relates to a method in which a terminal establishes component carriers in a wireless communication system. More particularly, the method comprising the following steps: determining whether or not a second component carrier, which is associated with a first component carrier by means of system information, exists; if the second component carrier exists, establishing a relationship between the second component carrier and the first component carrier; and, if the second component carrier does not exist, establishing a relationship between a primary component carrier and the first component carrier.

The present invention relates to a method for limiting measurement reports by limiting objects of measurement and evaluation for a measurement report, and user equipment therefore. The method for limiting measurement reports by user equipment in a mobile communication system according to the present invention comprises: receiving a cell list that includes information about at least one cell; receiving a measurement setup message that includes a measurement limiting command for limiting objects of measurement and evaluation to the at least one cell included in the cell list; measuring the quality of signals that are received from neighbor cells; performing the measurement and evaluation on the basis of the signal quality having been measured to determine whether the quality measurement should be reported; and transmitting a measurement report message that includes the information about measurement reports generated in accordance with the measurement and evaluation, wherein, in the measurement and evaluation step, whether the measurement should be reported is evaluated only for a received signal from the at least one cell included in the cell list.

A method and apparatus of reporting a measurement result in a wireless communication system is provided. A user equipment receives, from a base station, measurement configuration information comprising a reporting condition for triggering reporting of a measurement result on M component carriers among N component carriers, where M≦N. The user equipment determines whether the reporting condition is satisfied by measuring the N component carriers. If the reporting condition is satisfied, the user equipment reports a measurement result on the M component carriers to the base station.
