Abstract:
A method and a communications system are provided. The system includes a base station and a RNC. The base station does not report the RNC whether the base station supports an E-DPCCH power boost capability. The RNC is also informed whether a UE supports and E-DPCCH power boost capability. If the UE supports E-DPCCH power boost function, the RCE designates by default that the base station also supports the E-DPCCH power boost function even though the base station does not report whether it supports or not, and configures resources for the base station to perform channel estimation by using the E-DPCCH power boost feature for the UE. If the base station itself does not support E-DPCCH power boost capability, the base station configures its resources accordingly and performs the channel estimation by using DPCCH.
Abstract:
The present invention discloses a method, an apparatus and a system for acquiring load information. In one method, a source access controller and a target access controller can interact through RAT handover related messages so that a source RAT system can acquire load information of a target RAT system when an inter-RAT PS handover is performed. This enables load balancing between different RAT systems so as to guarantee communications quality of the systems. In another method of the present invention, the source access controller and the target access controller interact through a RAN RIM based load information request message and an RIM based load information response message, so that the source RAT system can acquire load information of the target RAT system before an inter-RAT PS domain handover is performed. This enables load balancing between different RAT systems so as to guarantee the communications quality of the systems.

The base station does not report the RNC whether the base station supports an E-DPCCH power boost capability. The RNC is also informed whether a UE supports and E-DPCCH power boost capability. If the UE supports E-DPCCH power boost function, the RCE designates by default that the base station also supports the E-DPCCH power boost function even though the base station does not report whether it supports or not, and configures resources for the base station to perform channel estimation by using the E-DPCCH power boost feature for the UE. Through the solution of the system, the accuracy of channel estimation can be improved and thus a bit error rate in high-speed data transmission can be reduced.
