Abstract: Provided is a cell reselection method performed by a terminal in a wireless communication system. The method includes: receiving first priority information for at least one frequency; receiving second priority information for the one or more frequencies; and selectively applying, based on the state of the terminal, any one of the first priority information and second priority information and performing cell reselection. The first priority information is provided through a connection rejection message and provides instructions on the priority for the one or more frequencies to be lowered. The second priority information is provided from a current cell through system information.

Abstract: Provided are a method for transmitting data performed by a user equipment (UE) comprising an upper layer, a switching layer and a lower layer in a wireless communication system and the UE using the same. The method includes receiving, in the switching layer, data from the upper layer, assigning a priority to the data in the switching layer, selecting a link among a plurality of links in the switching layer and transmitting, in the lower layer, the data using the selected link. Here, the link is selected based on the assigned priority of the data.

Abstract: While a user equipment (UE) performs a periodic transmission on a first link or a first carrier by using a semi-persistent scheduling (SPS) resource for the first link or the first carrier to an eNodeB (eNB), the UE may receive a SPS resource for a second link or a second carrier from the eNB. Or, a certain event may occur. Then, the UE stops using the SPS resource for the first link or the first carrier, and performs a periodic transmission on the second link or the second carrier by using the SPS resource for the second link or the second carrier to the eNB.
