Embodiment Construction

[0020]Please refer to FIG. 2, which is a functional block diagram of a communications device 100. For the sake of brevity, FIG. 2 only shows an input device 102, an output device 104, a control circuit 106, a central processing unit (CPU) 108, a memory 110, a program code 112, and a transceiver 114 of the communications device 100. In the communications device 100, the control circuit 106 executes the program code 112 in the memory 110 through the CPU 108, thereby controlling an operation of the communications device 100. The communications device 100 can receive signals input by a user through the input device 102, such as a keyboard, and can output images and sounds through the output device 104, such as a monitor or speakers. The transceiver 114 is used to receive and transmit wireless signals, delivering received signals to the control circuit 106, and outputting signals generated by the control circuit 106 wirelessly. From a perspective of a communications protocol framework, t...

Abstract

A method of improving reset of an evolved media access control (MAC-ehs) protocol entity for a user equipment of a wireless communications system is disclosed. The MAC-ehs entity includes a plurality of reordering queues and a plurality of reassembly entities. The method includes receiving a reset request for resetting the MAC-ehs entity, delivering all reordering packet data units (PDUs) stored in the plurality of reordering queues to the corresponding reassembly entities for performing a reassembly process to deliver complete upper layer PDUs to an upper layer entity, and discarding all PDU segments still existing in the plurality of reassembly entities.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60916546, filed on May 7, 2007 and entitled “Method and Apparatus for allocating HARQ configuration and concatenation and delivery of MAC PDUs”, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a method and apparatus for improving reset of an evolved media access control, named MAC-ehs hereinafter, protocol entity in a user equipment of a wireless communications system, and more particularly to a method and apparatus for resetting the MAC-ehs protocol entity by correctly discarding previously stored packet data unit segments in a user equipment in a wireless communications system.[0004]2. Description of the Prior Art[0005]The third generation (3G) mobile telecommunications system has adopted a Wideband Code Division Multiple Access (WCDMA) wireless air interface ...
