Abstract

The invention discloses a wireless base station, a medium access control system thereof and a data processing method. The wireless base station comprises a PHY layer and a MAC layer, the MAC layer comprises a MAC system, a MAC system comprises a bottom receiver which is used to finish receiving control information and data from a PHY layer, and receive data from wireless base layer PHY layer, analyze out PDU and PHY layers measuring information from data, and send the information to a receiving and processing apparatus, the receiving and processing apparatus which is used to finish receiving data, measuring communication channel, recording information, recombining data, managing a MAC layer, generating information and uploading SDU, which relatively processes according to the received data types which are SDU and PHY layers measuring information or MAC layer managing information, and the MAC system also comprises a sender which is used to cyclically invoke and renew data, generate relative information, and generate uplink frame with the PDU which is invoked to send to the PHY layer. The invention has high transportability and flexible high effectiveness.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless base station in a broadband wireless metropolitan area network (IEEE802.16 WirelessMAN), a media access control system and a data receiving and receiving processing method thereof. Background technique [0002] At present, research on the fourth generation mobile communication system (Fourth Generation, 4G) is being carried out extensively in the world, and its representative is the Institute of Electrical and Electronics Engineers (INSTITUTE OF ELECTRICALAND ELECTRONICS ENGINEERS, IEEE) 802.16 series standards (see Carl Eklund, Roger B. Marks, "IEEE Standard 802.16: A Technical Overview of the WirelessMAN TM Air Interface for Broadband Wireless Access", IEEEEC802.16-02 / 05, 2002). The IEEE 802.16 standard regulates the high-speed wireless access technology within the metropolitan area. The IEEE 802.16 working group released the IEEE Std 802.16-2004, wh...
