摘要:
A method of receiving a control signal by a user equipment in a wireless communication system is disclosed. The present invention includes receiving control regions including the control channel relevant to each of a plurality of component carriers via a plurality of component carriers and detecting the control channel for the user equipment by performing blind decoding by a unit of CCE (control channel element) aggregated at a preset level in a search space included in the control regions. And, start positions of the search spaces in the plurality of component carriers is in a certain relationship. Moreover, the preset level is identically set for each of the plurality of component carriers.

The present invention provides a method and device for effecting uplink HARQ (hybrid automatic repeat request) on a wireless communications system. A terminal receives HARQ setting data from a base station. If the terminal receives a NAC signal for an initial transmission block, the transmission characteristics of a retransmission block for the initial transmission block are adjusted on the basis of the HARQ setting data.

The present invention relates to a method for monitoring a control channel and an apparatus thereof. A reference carrier is set, and then the multi-carrier sends blind decoding area information based on the reference carrier to monitor a control channel. A terminal monitors the control channel based on the blind decoding area information. The terminal performs blind decoding only for a component carrier required, and thus reduces power consumption and reception complexity.

The present invention relates to a method and to an apparatus for random access in a wireless communication system to which carrier aggregation is applied. According to one aspect of the present invention, a method in which a base station supports random access of a terminal in a wireless communication system that supports carrier aggregation, comprises a step in which the base station allocates, to the terminal, a dedicated PRACH preamble for a second random access in an uplink component carrier (hereinafter, referred to as UL CC) which is additionally allocated or the configuration of which is changed after a first random access, and receives the dedicated PRACH preamble from the terminal.
摘要:
A wireless device and method for a multiple carrier system are provided. The wireless device comprises a carrier management unit for determining at least one of a plurality of carriers as a reference carrier for monitoring a control channel and a control channel unit for monitoring the control channel over the reference carrier, wherein the carrier management unit switches the reference carrier to at least one of remaining carriers of the plurality of carriers. Accordingly, control channel traffic can be prevented from concentrating on a particular carrier, and a diversity gain can be achieved.

The present invention relates to a method for allocating a relay backhaul resource in a wireless communication system and to an apparatus for same. In detail, the present invention provides a signal-receiving method in which a terminal receives a signal in a wireless communication system, and to an apparatus for same, wherein the method comprises a step of receiving, from a base station, information on one or more first resource blocks (RB) allocated for a relay, a step of receiving resource allocation information through a control channel from the base station, and a step of receiving a predetermined resource block indicated by the resource allocation information among logically continuous second resource blocks. The second resource blocks are logically continuous when excluding said one or more first resource blocks from the entirety of the resource block.

The present invention provides a method and an apparatus for transmitting a sounding reference signal. A terminal receives from a base station a sounding reference signal (SRS) configuration that includes a cell specific SRS configuration and a terminal specific SRS configuration, via a downlink carrier. The terminal then transmits a sounding reference signal based on the SRS configuration via an uplink carrier that is linked to the downlink carrier.
摘要:
Provided are a method and a device for monitoring the control channel in a multicarrier system. The terminal determines a plurality of terminal-specific search spaces corresponding respectively to a plurality of scheduled component carriers in a control region within a subframe. The terminal monitors a downlink control channel for the scheduled component carriers corresponding respectively to the plurality of terminal-specific search spaces.
摘要:
The present invention relates to a method and device for monitoring the control channel in a multicarrier system. Each of a plurality of sub-search spaces corresponds to each of a plurality of scheduled component carriers. The terminal monitors a downlink control channel for a scheduled component carrier corresponding to each of the plurality of sub-search spaces. Each of the plurality of sub-search spaces is defined displaced to the extent that they are offset from each other.
