Publication number: 20160066290Abstract: The present disclosure is directed to a system and method for performing timing synchronization via network listening. The system and method can be implemented in a non-synchronized base station to receive Cell-Specific Reference Signals (CRSs) of a synchronized base station during guard periods of special subframes. To allow the non-synchronized base station to receive the CRSs, the non-synchronized base station can configure one or more of its special subframes to have a shorter downlink part than corresponding special subframes of the synchronized base station. The system and method of the present disclosure can use the received CRSs to synchronize the timing of the non-synchronized base station to the timing of the synchronized base station. To prevent a substantial loss in downlink throughput due to the non-synchronized base station using a shorter DwPTS part, tracking can be performed on a once per multiple radio frame basis.Type: ApplicationFiled: September 3, 2014Publication date: March 3, 2016Applicant: Broadcom CorporationInventors: Yonatan COHEN, Sharon LEVY, Rafael CARMON

Patent number: 8958321Abstract: A method for managing power control of enhanced dedicated channel (E-DCH) uplink (UL) channels of at least one user equipment (UE) that is located on a femtocell base station (FBS), is provided herein. The method includes calculating, for the UE, a maximum dedicated physical control channel (DPCCH) power level. The method also includes lower, by the FBS, a DPCCH power level for the UE when the actual DPCCH power level is exceeding the maximum DPCCH power level for the UE. The lowering of the DPCCH power level is independent of a signal-to-interference (SIR) target for the FBS.Type: GrantFiled: February 1, 2012Date of Patent: February 17, 2015Assignee: Broadcom CorporationInventors: Sharon Levy, Felix Gess

Publication number: 20120202460Abstract: A method of invoking denial of service in 3G networks is provided. The method includes receiving a downlink UMTS signal that is operating at a downlink UMTs frequency provided by the UMTS base station. A reference downlink UMTS signal is provided with a reference downlink UMTS frequency. The reference downlink UMTs frequency is aligned with the downlink UMTS frequency based on a frequency offset between the downlink UMTS frequency and the reference downlink UMTS frequency to provide an aligned frequency. A common pilot channel (CPICH) is transmitted over the reference downlink UMTS signal operating at the aligned frequency. Service for the UMTS base station is denied when the CPICH is combined with a UMTS base station CPICH operating at the downlink frequency.Type: ApplicationFiled: February 2, 2012Publication date: August 9, 2012Applicant: Broadcom CorporationInventors: Felix GESS, Ilya DEGTYAR, Sharon LEVY, Benny ARVIV
