Problems solved by technology

In this case, if a high-priority logical channel has a large amount of data to transmit, due to the limitation that only one service-enhanced packet data unit can be transmitted in one transmission time interval, the service data cannot be transmitted as soon as possible, which may reduce its service quality

Embodiment Construction

[0014] Please refer to FIG. 1 , which is a functional block diagram of a wireless communication device 100 . For simplicity, FIG. 1 only shows an input device 102 , an output device 104 , a control circuit 106 , a CPU 108 , a storage device 110 , a program code 112 and a transceiver 114 of the wireless communication device 100 . In the wireless communication device 100, the control circuit 106 executes the program code 112 stored in the storage device 110 through the central processing unit 108, thereby controlling the operation of the wireless communication device 100, which can receive user input through the input device 102 (such as a keyboard) signals, or output images, sounds, and other signals through the output device 104 (such as a screen, a speaker, etc.). The transceiver 114 is used for receiving or sending wireless signals, and transmitting the received signals to the control circuit 106 , or outputting the signals generated by the control circuit 106 by radio. In ...

Abstract

In order to transmit available data of high priority services as soon as possible, the present invention provides a method of constructing packets in a wireless communications system. The wireless communications system has a medium access control layer. The method includes the following steps. A plurality of group packet data units, called PDUs hereinafter, corresponding to a logic channel is concatenated in a transmission time interval, called TTI hereinafter. The concatenated plurality of group PDUs is appended to a transmission PDU in the TTI. A plurality of data description signals with respect to the plurality of group PDUs is added into the transmission PDU during the TTI, where the plural data description signals are fully or partially the same.

Description

technical field [0001] The present invention relates to a method for constructing a group and its related device, in particular to a method for constructing a group in a Medium Access Control Layer (MAC Layer) of a wireless communication system and its related communication device. To improve an existing packet format. Background technique [0002] The third-generation mobile communication technology adopts the wireless access method of Wideband Code Division Multiple Access (WCDMA), which is used to provide high spectrum utilization efficiency, wide-ranging coverage and high-quality, high-speed multimedia Data transmission can meet various QoS service requirements at the same time, provide flexible and diversified two-way transmission services, provide better communication quality, and effectively reduce the communication interruption rate. Through the third-generation mobile communication system, users can realize real-time video communication, conference calls, real-time...
