Embodiment Construction

[0056] The solution of the present invention is especially suitable for WCDMA (Wideband Code Division Multiple Access), UMTS (Universal Mobile Telephone System) and IMT-2000 wireless systems. Thus, the invention is applicable to at least TDMA (Time Division Multiple Access) based and CDMA (Code Division Multiple Access) based wireless systems.

[0057] first pass figure 1 Examine how to send data according to existing technologies. In this example, the transmitter 90 only transmits signal 1 and signal 2 over the same channel, but the same principle can be applied to 3 or more signals that need to be transmitted. These signals are generally received with different quality standards. Carrier-to-interference ratio or bit error rate BER can be used as quality criterion. The BER of signal 1 is eg BER1=e -3 , while the BER of signal 2 is e.g. BER2=e -6. Since the quality requirements are signal-specific, these signals should be sent at different transmit powers / symbol rates. ...

Abstract

The invention relates to a data transmission method of a wireless system. The wireless system comprises at least one base station and a terminal including a receiver and a transmitter. The base station is communicated with the terminal through at least one physical channel. The method is characterized in that the transmitter transmits at least two signals on the physical channel, the signals have different quality requirements when being received. By eliminating codes and repeating codes, the transmitter changes the element rate of each signal to satisfy the quality requirements, combines the signals on the same physical channel.

Description

[0001] This application is a divisional application filed by Nokia Networks Co., Ltd. on March 25, 1999, the application number is 99800395.6, and the title of the invention is "Data Communication and Wireless Communication". technical field [0002] The invention relates to a data transmission method for a wireless system comprising at least one base station and terminal equipment including a receiver and a transmitter, the base station and the terminal equipment communicate with each other through at least one physical channel. [0003] The invention also relates to a wireless system, in particular a wireless system comprising at least one base station and a terminal device comprising a receiver and a transmitter, the base station and the terminal device communicating with each other via at least one physical channel. Background technique [0004] Existing mobile phone systems wish to provide users with an ever-increasing number and variety of services. IMT-2000 (Internati...
