A transmitting device, a transmit power control method and a control device thereof in a microwave system are provided. The transmitting device includes a transmit power control module, adapted to acquire a switching event of a modulation mode of the microwave system, and adjust a transmit power of a radio frequency transmitting module according to the switching event and a preset power control mode; and the radio frequency transmitting module, adapted to send a microwave signal to a communication peer end by adopting the transmit power adjusted by the transmit power control module. Through setting the power control module, the gain of an AM microwave system is enhanced, and the service impairment caused by the AM microwave system when actuating an ATPC function is avoided. Correspondingly, a transmit power control method in a microwave system is also provided, which enables to switch to a low modulation mode as quickly as possible without causing the service impairment when the signal is deteriorated and enhances the system gain when the signal quality is improved.

A method provided by the present invention for transmitting overhead information, includes dividing and reforming overhead information into at least two overhead parts, inserting the at least two overhead parts into overhead bytes of at least two corresponding data frames, and transmitting the at least two overhead parts via the at least two data frames which are microwave frames. Overhead information transmitting apparatus and overhead information receiving apparatus are also provided by the present invention. With the method and apparatus of the present invention, the channel bandwidth resources occupied by the overhead bytes or each microwave frame are greatly reduced. If the saved channel bandwidth is used for performing the error correction code on the transmitted information, the code gain is improved and the sensitivity requirement on the receiver is reduced so that the cost of a microwave transmitting system is reduced eventually.
