    • The present invention involves defining the operation of a terminal for determining which time alignment timer is to be applied to a certain condition when specific time alignment timers operate for each carrier-wave group in the event a wireless communication system uses a carrier aggregation technique. According to the present invention, a terminal may perform communication without malfunctions using a time alignment timer suitable for a certain condition. In detail, a method for a terminal to operate a time alignment timer according to the present invention comprises the steps of: receiving, from a base station, a message including a timing advance command and an index on a timing advance group (TAG); and operating the time alignment timer for the TAG, wherein the index has a value of 00 when the TAG includes a first cell. In the meantime, a method for a terminal to operate a time alignment timer according to the present invention comprises the steps of: operating a first time alignment timer for a first timing advance group (TAG) including a first cell; operating a second time alignment timer upon receipt of a timing advance command for a second TAG that does not include the first cell; and, if the first time alignment timer has expired, deeming the second time alignment timer to also be expired. In addition, a method for a base station to control a time alignment timer according to the present invention comprises the steps of: determining whether or not an uplink timing of a terminal needs correction; and transmitting a message including a timing advance command and an index on a timing advance group (TAG), wherein the index has a value of 00 when the TAG includes a first cell.
    • 本发明涉及在无线通信系统使用载波聚合技术的情况下,当特定的时间对准定时器对每个载波组进行操作时,定义终端的操作,以确定将哪个时间对准定时器应用于特定条件。 根据本发明,终端可以使用适合于一定条件的时间对准定时器来执行无故障的通信。 具体地说,根据本发明的终端操作时间对准定时器的方法包括以下步骤:从基站接收包括定时提前命令和定时提前组(TAG)上的索引的消息; 以及操作TAG的时间对准定时器,其中当TAG包括第一小区时,该索引具有值00。 同时,根据本发明的终端操作时间对准定时器的方法包括以下步骤:为包括第一小区的第一定时提前组(TAG)操作第一时间对准定时器; 在接收到不包括第一小区的第二TAG的定时提前命令时操作第二时间对准定时器; 并且如果第一次对准定时器已经到期,则认为第二时间对准定时器也到期。 此外,根据本发明的基站控制时间对准定时器的方法包括以下步骤:确定终端的上行链路定时是否需要校正; 以及在定时提前组(TAG)上发送包括定时提前命令和索引的消息,其中当所述TAG包括第一小区时,所述索引具有值00。

    • A method and an apparatus for configuring uplink transmission power and apparatus in a mobile communication system supporting downlink and uplink carrier aggregation are provided. The method includes determining a per-terminal maximum transmission power and per-serving cell maximum transmission powers based on ?TC,c as a value for allowing an adjustment of additional transmission power for multiple serving cells, Maximum Power Reductionc (MPRc) as a value determined according to an amount of transmission resources allocated to the terminal, and Additive-MPRc (A-MPRc) as a value determined according to local characteristics and frequency band characteristics, determining per-serving cell uplink transmission powers by restricting required transmission powers for respective serving cells to the corresponding per-serving cell maximum transmission powers, comparing a sum of the per-serving cell uplink transmission powers with the per-terminal maximum transmission power, and adjusting the per-serving cell uplink transmission powers according to comparison result.
