    摘要: A method and an apparatus for transmitting and receiving Time Division Duplex (TDD) frame configuration information are disclosed. The base station transmits TDD frame configuration information as system information to a user equipment through a common control channel so as to dynamically change the TDD frame configuration according to uplink and downlink traffic conditions. The base station may deliver the same system information to all user equipments in the cell, removing ambiguity in User Equipment (UE) operations and avoiding interference. In comparison to an existing method of delivering TDD frame configuration information through system information update, the disclosed method enables user equipments to rapidly cope with traffic changes. In addition, user equipments may receive and apply TDD frame configuration information at the same time.

    摘要: Methods and apparatus are provided to support HARQ in a communication system adopting cross-carrier scheduling. A second cell is scheduled at a first cell. Data, transmitted by a terminal, at a subframe of the second cell is received. A subframe, in the first cell, is determined for transmitting a HARQ acknowledgement corresponding to the data, and a subframe, in the first cell, is determined carrying scheduling information of the second cell. It is determined whether the subframe for transmitting the HARQ acknowledgement and the subframe carrying scheduling information of the second cell are the same. When the subframe for transmitting the HARQ acknowledgement and the subframe carrying the scheduling information are not the same, the subframe for transmitting the HARQ acknowledgement and the subframe carrying the scheduling information are matched to each other.

    摘要: Methods and apparatus for transmitting and receiving signals are provided for facilitating a cell search in a wireless communication system supporting various types of multicarrier transmission. A carrier type indication signal indicating a type of carrier supported by the base station is generated. The carrier type indication signal is transmitted with synchronization signals, to one or more terminals in a cell of the base station. A type of a carrier supported by a base station is determined based on a carrier type indication signal transmitted by the base station. A cell search procedure is performed to access the base station according to the type of the carrier supported by the base station.

    摘要: A method and an apparatus for operating a subframe and transmitting channel information for controlling interference in a communication system are provided. If a macro evolved Node B (eNodeB) determines and reports an uplink protection subframe for suppressing uplink transmission to a neighboring eNodeB, transmits scheduling information for uplink data through a downlink subframe corresponding to an uplink protection subframe, and the uplink protection subframe determined by the neighboring eNodeB is reported, a small eNodeB sets the reported uplink protection subframe as a flexible subframe, and uses the flexible subframe for downlink transmission. If the flexible subframe is used for the downlink transmission, a terminal of the small eNodeB measures and transmits non-period channel information in the flexible subframe through at least one uplink subframe.
