Problems solved by technology

Then, for most of the HS TTI 24 with very low HS Tx power, the SIR target for most DCH users is much higher than needed, which is clearly a waste of power
[0006] For the second solution, except as figure 2 In addition to the similar power interaction between HS and DCH in , there is another problem - low power utilization efficiency, because the HS power limit does not change, even when encountering very high HS and very low DCH More power can be allocated for HS service when traffic load is encountered or more power can be allocated for DCH service when encountering very low HS and very high DCH traffic load

Embodiment Construction

[0029] figure 1 A communication system (such as a WCDMA communication system) comprising a Radio Access Network (RAN) such as a UMTS Terrestrial Radio Access Network (UTRAN) architecture is depicted, which includes connections to one or more Radio Network Controllers (RNCs) 10 At least one radio base station (RBS) (or Node B) 15 ( figure 1 Two are shown in ). The RAN is connected to a core network (CN) 12 . The RAN and CN 12 provide communication and control for multiple user equipments (UEs) 18, each using downlink (DL) and uplink (UL) channels. On the downlink channel, the RBS 15 transmits data to each user equipment 18 at a respective power level. On the uplink channel, the user equipment 18 transmits data to the RBS 15 at respective power levels. According to a preferred embodiment of the present invention, the communication system is described herein as a WCDMA communication system. However, those skilled in the art will recognize that the method and apparatus of t...

Abstract

The invention relates to a method and an arrangement of efficiently utilizing radio resources in a communication network, comprising a communication network node communicating with one or more user equipments over a radio interface, wherein at least two communication services are provided on said radio interface, each having a certain amount of power allocated in an interactively way. The interaction between said at least two communication services is minimized in order to obtain an enhanced power utilization.

Description

technical field [0001] The present invention relates to a method and a device in a communication system, in particular to a device capable of effectively utilizing wireless resources in a communication network and a method for realizing such utilization. The invention also relates to a computer readable medium containing a computer program for efficient utilization of radio resources in a communication network. Background technique [0002] Telecommunication systems according to 3GPP standards offer high and variable bit rates and are able to provide users with new types of services including real-time audio and video, still images and text, such as news, sports scores and weather forecasts. With High Speed ​​Downlink Packet Access (HSDPA), a feature of the 3GPP standard, system capacity and peak data rates are increased in the downlink direction, while transmission delays are reduced. In order to use HSDPA services, users must have user equipment that supports HSDPA, other...
