  • Patent number: 9872278
    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.
