    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： A method of defining physical channel transmit/receiving timings and resource allocation is provided for use in a Time Division Duplex (TDD) communication system supporting carrier aggregation. A method for receiving, at a base station, a Hybrid Automatic Repeat Request (HARQ) acknowledgement from a terminal in a Time Division Duplex (TDD) system supporting carrier aggregation of a primary cell and at least one secondary cell includes transmitting a downlink physical channel through one of the primary and secondary cells, receiving the HARQ acknowledgement corresponding to the downlink physical channel of the primary cell at a first timing predetermined for the primary cell, and receiving the HARQ acknowledgement corresponding to the downlink physical channel of the secondary cell at second timing, wherein the second timing is determined according to the first timing.
