Patent number: 9870855Abstract: Multiplexing circuitry is disclosed that includes filtering circuitry, which provides a first transfer function between a common port and a first port and a second transfer function between the common port and a second port. The first transfer function and second transfer function provide a first passband and a second passband, respectively. The first transfer function also has a stopband provided within the second passband of the second transfer function because the filtering circuitry includes a first filter path and a second filter path, wherein the second filter path has a first and second parallel resonant circuit provided in shunt with respect to the second filter path and weakly coupled to one another.

Patent number: 9872278Abstract: 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.Type: GrantFiled: October 29, 2014Date of Patent: January 16, 2018Assignee: Huawei Technologies Co., Ltd.Inventors: Shukun Wang, Dingzhang Dai, Xin Huang, Boya Lv
