    摘要： A method and apparatus for transmitting HARQ-ACK information are provided. The method includes: in a CA TDD system, when uplink-downlink configurations of aggregated serving cells are different, and a mode of PUCCH format 1b with channel selection is configured to be used to feed back the HARQ-ACK, determining, according to a timing relationship between the PDSCH and the HARQ-ACK information complied by a secondary serving cell, a set of downlink subframes of aggregated serving cells in a feedback window corresponding to an uplink subframe; and determining, according to the relationship between the sets of downlink subframes of the aggregated serving cells in a feedback window corresponding to uplink subframe, the transmission mode of the HARQ-ACK information of the serving cells and the used PUCCH resources when transmitting the HARQ-ACK information; and on the determined PUCCH resources, transmitting the HARQ-ACK information by using the determined transmission mode of the HARQ-ACK information.

    摘要： A transmitting method of a signal on a random access channel in a wireless communication system, comprises the steps that: a terminal transmits a preamble on the random access channel with a set time length ahead of the end position of an uplink pilot time slot, and the length of the preamble is the length of two symbols without a cyclic prefix. Another transmitting method of a signal on a random access channel in a wireless communication system, comprises the steps that: a terminal transmits a cyclic prefix and a preamble on the random access channel with a set time length ahead of the end position of an uplink pilot time slot, and the length of the preamble is the length of two symbols without a cyclic prefix. The methods can avoid the interference of the preamble to the data of the uplink subframe, and can improve the coverage area of the random access channel and the work efficiency of the time division duplex system.

    摘要： A signal transmission method in a Time Division Duplex (TDD) system is disclosed. The method comprises following steps: within a time length of a half-frame of a radio frame, base station transmits signal on a downlink special time slot, thereafter does not transmit signal on a Guard Period (GP), and then receives signal on an uplink special time slot; all time lengths of other uplink or downlink normal time slots for transmitting signal are equal; the total time length of the downlink special time slot, the guard period and the uplink special time slot is integer times of the time length of an uplink or downlink normal time slot. In addition, a frame structure adopted in the TDD system which corresponds to the method is disclosed. The present invention makes it flexible to set the duration of the GP and it is guaranteed that, even if a synchronization signal adopts power promotion, it will not bring great interference to uplink reception of other base stations; in addition, the utilization efficiency of the system is improved.
