Method and apparatus for transmitting overhead information

A method for receiving overhead information, comprising:

• receiving at least a first and a second microwave data frame;
• reading an overhead byte from the first microwave data frame, and an overhead byte from the second microwave data frame;
• and
• parsing the overhead byte from the first microwave data frame to obtain a first overhead part according to a first microwave multi-frame indication in the first microwave data frame;
• and
• parsing the second overhead byte from the second microwave data frame to obtain a second overhead part according to a second microwave multi-frame indication in the second microwave data frame;
• and
• assembling the first overhead part and the second overhead part to obtain the overhead information corresponding to a division method from a transmitting party,
• wherein the first overhead part and the second overhead part each comprises an Adaptive Transmission Power Control (ATPC), a microwave Link path Identification (Link ID), a microwave frame channel performance state detection byte (MVV5), and a microwave frame signal trace byte (MVJ0).

An overhead information transmitting apparatus, comprising:

• an overhead part generating unit, configured to divide each of several overhead information parts of overhead information of a microwave frame into at least a first and a second overhead part, and multiplex the first overhead part of each of the several overhead information parts to generate first overhead information;
• and multiplex the second overhead part of each of the several overhead information parts to generate second overhead information;
• and combine the first overhead information and a first microwave multi-frame indication, and combine the second overhead information and a second microwave multi-frame indication, wherein the several overhead information parts comprise an Adaptive Transmission Power Control (ATPC), a microwave Link path Identification (Link ID), a microwave frame channel performance state detection byte (MVV5), and a microwave frame signal trace byte (MVJ0);
• and
• a data frame generating unit, configured to insert the combination of the first overhead information and the first microwave multi-frame indication received from the overhead part generating unit into an overhead of a first microwave data frame, and to insert the combination of the second overhead information and the second microwave multi-frame indication received from the overhead part generating unit into an overhead of a second microwave data frame, and transmit the first and the second microwave data frames.

An overhead information receiving apparatus, comprising:

• a data frame receiving unit, configured to receive at least a first and a second microwave data frame, and read an overhead byte from the first microwave data frame, and an overhead byte from the second microwave data frame;
• and
• an overhead information recovering unit, configured to parse the overhead byte from the first microwave data frame to obtain a first overhead part according to a first microwave multi-frame indication combined in the first microwave data frame;
• and parse the overhead byte from the second microwave data frame to obtain a second overhead part according to a second microwave multi-frame indication combined in the second microwave data frame;
• and assemble the first overhead part and the second overhead part to obtain the overhead information corresponding to a division method from a transmitting party,
• wherein the first overhead part and the second overhead part each comprises an Adaptive Transmission Power Control (ATPC), a microwave Link path Identification (Link ID), a microwave frame channel performance state detection byte (MVV5), and a microwave frame signal trace byte (MVJ0).
