Patent number: 8718018Abstract: A user equipment (UE) is provided which reduces uplink signaling overhead in the process of reporting inter-frequency measurement results over a RACH. For measurement reporting, the UE receives an SIB including a cell information list for non-used frequency cells and a threshold from an RNC, compares signal strengths of signals received from the non-used frequency cells with the threshold, and acquires at least one inter-frequency cell ID indicating at least one non-used frequency cell having signal strength exceeding the threshold from the cell information list. The at least one inter-frequency cell ID is included in a RACH message as measurement result information for the at least one non-used frequency cell, and transmitted to the RNC. The RNC determines that the cell corresponding to the inter-frequency cell ID has signal strength exceeding the threshold.Type: GrantFiled: September 14, 2012Date of Patent: May 6, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Kyeong-In Jeong, Gert Jan Van Lieshout, Himke Van Dervelde, No-Jun Kwak

Patent number: 8718542Abstract: A wireless communication system and method comprising co-location of a pico evolved node B (“eNB”) and a macro up-link repeater is disclosed. User Equipment (“UE”) communicates with a macro eNB via the up-link repeater with reduced transmission power as compared to the transmission power required for the UE to communicate directly with the macro eNB. As a result, the UE does not desensitize the pico eNB receiver. The up-link repeater comprises a donor antenna that radiates a highly directional beam to the macro eNB.Type: GrantFiled: September 22, 2010Date of Patent: May 6, 2014Assignee: Powerwave Technologies S.a.r.l.Inventor: Richard Neil Braithwaite

Patent number: 8699942Abstract: A method and arrangement in a first node (101) for determining radio characteristics of a radio link between a first repeater (103, 203) and at least one second repeater (104, 204) are provided. The first node sends a first message, to the first repeater (103, 203), instructing the first repeater (103, 203) to send a radio signal being measureable by the second repeater (104, 204). Furthermore, the first node sends a second message, to said at least one second repeater, instructing said at least one second repeater (104, 204) to measure on the radio signal. The first node receives measurement data of the radio signal, measured by said at least one second repeater (104, 204). The first node (101) determines radio characteristics of the radio link between the first repeater (103, 203) and said at least one second repeater based on the measurement data.Type: GrantFiled: November 18, 2008Date of Patent: April 15, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Pål Frenger, Niklas Johansson, Peter Larsson
