  • Publication number: 20140050230
    Abstract: Disclosed is a wireless communication method, comprising: determining a type of a media access control MAC frame header according to a type of a media access control protocol data unit MPDU; assigning a value to a function field in the MAC frame header to generate the MAC frame header; generating an MPDU, the MPDU at least comprising the MAC frame header; and encapsulating the MPDU and sending the encapsulated MPDU. Further disclosed are a transmitting device and a receiving device. By using the method and devices of the present invention, a signaling format having complete functions and compact structure and being easy to implement and extend is implemented, which is applicable to a newly defined medium-to-short distance wireless communication system, and reduces the complexity in processing.

  • Publication number: 20110188605
    Abstract: A framing method of the common interleaved frame is provided, which includes the following steps: obtaining the position information of each sub-channel in the common interleaved frame; depositing data bits in each sub-channel accordingly based on the position information of each sub-channel and the number of bits comprised in the capacity unit CU; wherein the number of bits comprised in the CU is determined by a symbol mapping mode of each sub-channel. The method can help the skilled in the art to make a CIF with the data bits at the transmitter of the T-MMB system. A framing device of the common interleaved frame is also provided in the present invention.
