Embodiment Construction

[0017] The present invention can be applied to various wireless systems employing the Code Division Multiple Access (CDMA) method. These examples describe the application of the invention in a cellular radio network. The general structure of the cellular wireless network is shown in Figure 1. Fig. 1 only includes blocks relevant to describing the present invention, and it is obvious to a skilled person that a conventional cellular radio network also includes other functions and structures, which need not be described in detail here. Examples of wireless systems according to the present invention are as follows: European future mobile phone system, i.e. broadband wireless system (WCDMA wireless system) using code division multiple access, UMTS system (Universal Mobile Telephone System), and ITM-2000 system (International Mobile Phone 2000). These examples are based on the WCDMA system, and its description is detailed in ETSI (European Telecommunications Standards Institute) t...

Abstract

The invention relates to a method of physical channel power control in a radio system and to a radio system. The method comprises (458) establishing a physical channel with at least one spreading code, (452) placing at least one service in the physical channel, and (464) performing physical channel power control according to the carrier / interference target set for the physical channel. According to the invention one service is (460) selected from among the active services placed in the physical channel, and the carrier / interference target of the one selected service is (462) set to lead physical channel power control.

Description

technical field [0001] The present invention relates to a method of physical channel power control in a wireless system, the method comprising: using at least one spreading code to establish a physical channel; arranging at least one service on the physical channel; according to the carrier / interference index set for the physical channel Perform physical channel power control. Background technique [0002] According to the prior art, the power control of a physical channel is performed according to the carrier / interference index set for the channel. In the prior art, only one kind of service is sent on the physical channel at a certain time. It is problematic if several different services such as user's voice, moving video images or data are transmitted simultaneously on the physical channel, because the power control is not optimized as the channel conditions change. Each service has its own quality requirements and has different channel coding and interleaving schemes. ...
