摘要： Disclosed are a method for transceiving data in a wireless access system, and a base station and terminal therefor. More particularly, the present invention relates to a method for transceiving data, and to a base station device for the method, wherein the method comprises the steps of: transmitting, in a single first subframe, a physical downlink control channel (PDCCH) including downlink scheduling information on each terminal; and transmitting, in a plurality of second subframes, a physical downlink shared channel (PDSCH) relevant to said PDCCH to each terminal. The PDCCH supports a carrier aggregation that includes a field indicating said plurality of second subframes in which said PDSCH is transmitted.

摘要： The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting uplink control information, and to an apparatus for the method, wherein the method comprises the steps of: generating a plurality of HRAQ-ACKs; selecting, from among a plurality of resource indices, one first resource index, and two second resource indices, each corresponding to the plurality of HARQ-ACKs; transmitting, through a first antenna port, a first modulation symbol corresponding to the plurality of HARQ-ACKs and a first reference signal for demodulating the first modulation symbol; and transmitting, through a second antenna port, a second modulation symbol corresponding to the plurality of HARQ-ACKs and a second reference signal for demodulating the second modulation symbol. Both a transmission resource for the first modulation symbol and a transmission resource for the first reference signal are given using said one first resource index. A transmission resource for the second modulation symbol is given using one of said two second resource indices, and a transmission resource for the second reference signal is given using the other of said two second resource indices.

摘要： The present invention relates to methods of allocating a Timing Advance (TA) value used for at least one timing advance group in a wireless access system for supporting carrier aggregation (CA), methods of adjusting a wireless frame transmission time by using the TA value, and devices for supporting same. According to one embodiment of the present invention, a method of adjusting transmission timing for at least one TA group in a wireless access system for supporting CA includes: receiving, by a terminal, a physical downlink control channel (PDCCH) signal including a reserved bit (i.e. a TA group indicator) indicating at least one TA group; receiving a medium access control (MAC) message including at least one TA value corresponding to at least one TA group; and transmitting an uplink signal by applying a TA value corresponding to a TA group in the TA group that the reserved bit indicates. At this point, each of the at least one TA group may include at least one primary cell (i.e. a P cell).

摘要： Disclosed are a method for transceiving a preamble in a wireless access system that supports a carrier aggregation/multi cells, and an apparatus for the same. More particularly, the method of the present invention comprises a step of transmitting a preamble to a terminal via an extension carrier that does not operate as a single carrier but operates only as a portion of a carrier aggregation. The preamble is generated based on a pseudo-random sequence.

摘要： The present invention relates to a method for transmitting and receiving synchronization signals in a wireless access system for supporting carrier aggregation/multiple cells (CA) and an apparatus therefor. Specifically, the present invention includes the steps of transmitting a first synchronization signal through an extension carrier which is not operated as a single carrier but is operated as a part of the CA, wherein a transmission area of the first synchronization signal differs from a transmission area of a second synchronization signal which is transmitted through a legacy carrier capable of being operated as the single carrier.
