    摘要： The present invention provides a method for accessing a wireless network, so as to implement acquisition of system synchronization during the process of accessing the wireless network in the situation that a physical frame structure can be configured dynamically. The method for acquiring system synchronization comprises: searching a physical frame on a current sub-channel; resolving a system information channel (SICH) and a control channel (CCH) in the found physical frame, wherein the SICH indicates a structure of the physical frame, and the CCH indicates allocation of system resources; and acquiring a system parameter from the physical frame by using the resolving result. A device for implementing the above method is further provided.

    摘要： Disclosed is a communication method comprising: determining the length, N, of a random access sequence on the basis of system configuration information, where N is less than or equal to the number of available subcarriers; determining a cyclic shift parameter collection and a cyclic prefix on the basis of a system coverage area as designed; acquiring and on the basis of a MAC address of a central access point (CAP), or of a physical layer identifier thereof, and of a predetermined generator polynomial, generating a PN sequence of length N, then constellation-mapping and subcarrier-mapping the PN sequence; cyclically shifting, on the basis of the cyclic shift parameter, the constellation-mapped and subcarrier-mapped sequence, then orthogonally transforming the cyclically shifted sequence; acquiring the sequence needed, adding the cyclic prefix thereto, acquiring a random access signal; and performing subsequent processing then transmitting to a receiving-end. Also provided in the present invention is a corresponding communication system. The present invention provides improved support for wireless communication system random access, and improved system stability and reliability.
