    Abstract: The present invention relates to a method for cell selection in a wireless communication system. The method for cell selection by a terminal according to one embodiment of the present invention may comprise the following steps: measuring the channel quality of a first cell; measuring the channel quality of a second cell; determining whether the value obtained by applying an offset to the result of the measurement of the channel quality of the second cell is better than the result of the measurement of the channel quality of the first cell; if the value obtained by applying an offset to the result of the measurement of the channel quality of the second cell is better than the result of the measurement of the channel quality of the first cell, determining whether the value obtained by applying no offset to the result of the measurement of the channel quality of the second cell is better than a preset reference value; and, if the value obtained by applying no offset to the result of the measurement of the channel quality of the second cell is better than the preset reference value, selecting the second cell. According to one embodiment of the present invention, an operable cell can be selected to prevent malfunctions, and interference from a CSG cell may be reduced.

    Abstract: Operation of a terminal for determining which time alignment timer is applied to a certain condition when specific timers operate for each carrier-wave group in the event a wireless communication system using carrier aggregation techniques. A terminal performs communication without malfunctions using a timer suitable for a certain condition. The terminal operates the timer by receiving, from a base station, a message including a timing advance command and an index on a timing advance group (TAG), operating the timer for the TAG, the index has a value of 00 when the TAG includes a first cell. A terminal operates a timer by operating a first timer for a TAG including a first cell, operating a second timer upon receipt of a timing advance command for a second TAG that does not include the first cell, and, if the first timer has expired, deeming the second timer to also be expired.

    Abstract: A user equipment (2) has an ability to operate according to one or more spectrum emission requirement capability values (14) in a wireless communications network having at least a first serving cell (4). A message (6) is received at the user equipment (2) from the first serving cell (4) comprising a first indicator representing a first band designation (8), a second indicator representing a spectrum emission requirement value (10), and at least one additional indicator representing at least one additional spectrum emission requirement value (12), both the first and additional indicators relating to the first band designation. The user equipment (2) performs a comparison of the first and additional spectrum emission requirement values (10, 12) with the one or more spectrum emission requirement capability values (14) and determines a behaviour of the user equipment (2) in relation to the first serving cell (4) in dependence on the comparison.
