Embodiment Construction
[0020] Certain terms are used throughout the specification and following claims to refer to particular components. Those skilled in the art can understand that a manufacturer may use different terms to refer to the same component. This description and the following claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a distinguishing criterion. The "comprising" mentioned throughout the specification and subsequent claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect means of electrical connection. With the narration of the following specific embodiments and in conjunction with the full text Figure 1 to Figure 10 The present invention is illustrated, but the devices, components, methods, and steps in the following description are used to explain the present invention, and should not be used to limi...

An apparatus for performing downlink or uplink processing in a wireless communication system and a data processing method. An apparatus for performing downlink processing in a wireless communication system to maintain efficiency of system bandwidth includes a sharing-ring buffer, a MAC-PHY interface, a security engine, and a DMA processor. The sharing-ring buffer is for storing multi-format data.The MAC-PHY interface is for receiving input data and storing the input data into the sharing-ring buffer to form stored data, the security engine is for retrieving stored data from the sharing-ring buffer, decrypting the retrieved data to form decrypted data and storing the decrypted data in the sharing-ring buffer, and the DMA processor is for accessing the sharing-ring buffer to obtain the decrypted data. The method and apparatus of the present invention is capable of improving the whole operating rate of the a wireless communication system and remarkably reducing the scale of the wirelesscommunication system.
Description
technical field [0001] The present invention relates to wireless communication, and more specifically, to a device and data processing method for performing downlink (DL) or uplink (uplink) processing in a wireless communication system. Background technique [0002] figure 1 It is a schematic diagram of a typical frame (ftame) structure applied in a wireless communication system according to the prior art, wherein the wireless communication system is, for example, a Worldwide Interoperability Microwave Access (WiMAX) communication system. WiMAX communication system can be based on figure 1 A schematic diagram of the frame structure shown in , using downlink bursts (bursts) as well as uplink bursts for communication. exist figure 1 In , taking Orthogonal Frequency Division Multiple Access (OFDMA) as an example, the figure shows information contained in OFDMA symbols and burst content. Taking the kth to k+33th symbols of OFDMA symbols as an example, wherein, the kth symbol...
