Abstract: To solve the above-mentioned problem, the method for transmitting and receiving a signal by user equipment (UE) through one or more cells, according to one embodiment of the present specification, comprises the steps of: receiving, from a base station, a first message indicating whether one or more cells usable by the UE are enabled; determining which cells to enable or disable on the basis of the first message; and enabling or disabling the selected cells. According to the embodiment of the present specification, by aggregating carriers amongst different base stations, a possibility for the UE to transmit and receive high-speed data through carrier aggregation can increase.

Abstract: A bearer reconfiguration method performed by a User Equipment (UE) in a wireless communication system supporting a multi-bearer is provided. The bearer reconfiguration method includes, if the UE performs a bearer reconfiguration from a single bearer to the multi-bearer, reordering Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) received through the multi-bearer, using a timer after a completion of the bearer reconfiguration, and processing the reordered PDCP PDUs into at least one PDCP Service Data Unit (SDU). The method may also include, if the UE performs bearer reconfiguration from the multi-bearer to the single bearer, reordering PDCP PDUs received through the multi-bearer, using a timer until a predetermined condition is satisfied, and processing the reordered PDCP PDUs into at least one PDCP SDU.

Abstract: Method for radio communication with base station, by user equipment (UE), apparatus in UE for radio communication with base station, a method for radio communication with a UE by a base station, and an apparatus in a base station for radio communication with a UE are provided. The method for radio communication with a base station, by a UE, includes identifying whether an uplink resource allocated for data transmission to the base station is available, in response to a buffer status report for transmission to the base station being triggered; transmitting an uplink packet including the buffer status report using the available uplink resource, in response to the uplink resource being available; and transmitting a scheduling request to the base station, in response to the UE not having an available uplink resource and a first timer being expired, wherein the first timer starts when the buffer status report is triggered.

Abstract: Methods and apparatuses are provided for establishing time alignment by a User Equipment (UE) in a wireless communication system. Information for identifying a dedicated preamble on a downlink control channel is received from a base station. The dedicated preamble is transmitted to the base station based on the information. A response message to the transmitted dedicated preamble is received from the base station on a downlink shared channel. The response message includes a timing adjustment information and information for a Channel Quality Indicator (CQI) report. Time alignment is established based on the timing adjustment information included in the response message. The CQI report based on the information for CQI report is transmitted to the base station.
