摘要:
The present invention relates to a method and an apparatus for transmitting/receiving a control format indicator channel for a relay backhaul link in a wireless communication system. According to one aspect of the present invention, a method for transmitting a control format indicator channel for a relay backhaul link in a wireless communication system is configured such that a base station generates a relay physical control format indicator channel (hereinafter, referred to as “R-PCFICH”) containing information on a relay physical downlink control channel (hereinafter, referred to as “R-PDCCH”) region, and transmits the R-PCFICH through a first OFDM symbol of the R-PDCCH region.
摘要:
Provided is a method for transmitting an acknowledgment through a base station in a multi-carrier system. The method for transmitting the acknowledgment through the base station in the multi-carrier system comprises the steps of receiving a plurality of uplink transmission blocks through at least one uplink carrier; determining a downlink channel for transmitting a plurality of ACK/NACK signals corresponding to the transmission blocks on the basis of the at least one uplink carrier; and transmitting the ACK/NACK signals on the determined downlink channel.

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.

摘要:
The present invention relates to a method and device for monitoring the control channel in a multiple carrier system. A terminal determines an extended search space comprising a plurality of sub-search spaces, and each of the plurality of sub-search spaces corresponds to at least one of a plurality of scheduled component carriers. The terminal monitors a downlink control channel for the scheduled component carrier corresponding to each of the plurality of sub-search spaces. At least one of the plurality of sub-search spaces is a shared sub-search space corresponding to at least two of the plurality of scheduled component carriers.

Provided are an apparatus and a method for monitoring a control channel in a multi-carrier system. A plurality of sub-search spaces within an extended search space corresponds to a plurality of scheduled component carriers, respectively. Each of the plurality of sub-search spaces includes a plurality of control channel elements (CCEs), and the CCEs of the plurality of sub-search spaces are interleaved with each another within the extended search space.
摘要:
Provided are a cell searching method and an apparatus in a multi-carrier system. A terminal acquires a first physical cell identity (PCI) for a first downlink component carrier, and acquires an expanded PCI for a second downlink component carrier. A first downlink reference signal through the first downlink element carrier is transmitted on the basis of the PCI, and a second downlink reference signal through the second downlink component carrier is transmitted on the basis of the expanded PCI.
