Patent number: 8654701Abstract: A method of supporting frequency-selective repeaters (eNodeRs) in a wireless telecommunication system. A base station (eNodeB) classifies User Equipments (UEs) into two categories or lists of users: a white list containing UEs that may need the assistance of repeaters, and a black list containing UEs that do not need repeater assistance. The eNodeB transmits one of these two lists to the eNodeRs. The eNodeRs do not amplify resource blocks (RBs) scheduled for black list UEs. Each repeater may decide on its own whether to amplify signals for a non-black list UE by measuring signals from the UE and comparing them with predefined criteria.Type: GrantFiled: October 16, 2009Date of Patent: February 18, 2014Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Muhammad Kazmi, Jiansong Gan, Robert Baldemair, Zhang Zhang

Patent number: 8649816Abstract: The wireless communication system is configured to adaptively change a status report (SR) cycle and a discontinuous reception (DRX) cycle on the basis of a quality of a radio link between a terminal device and a network device. When the quality of the radio link is good, the DRX cycle or the SR cycle is lengthened accordingly, and when the quality of the radio link is poor, the DRX cycle or the SR cycle is shortened accordingly. Furthermore, when the quality of the radio link is good for a long time, the power consumption can be significantly reduced by turning off the terminal device, and after a certain time, turning on the device.Type: GrantFiled: December 16, 2011Date of Patent: February 11, 2014Assignee: Electronics and Telecommunications Research InstituteInventor: Pyeong Jung Song

Patent number: 8649731Abstract: Provided is a communication system that can allocate resources on an uplink for a CQI report, and can reduce the overhead of the CQI relay transmission from a relay station apparatus to a base station apparatus. To each mobile station apparatus (501, 502) that transmits CQI directly to a base station apparatus (500), resource blocks on a base station apparatus uplink to be used for the transmission of each CQI to the base station apparatus are allocated. Resource blocks on the base station apparatus uplink to be used for each relay station to relay-transmit to the base station apparatus CQI received from the mobile station apparatuses are allocated on the basis of the allocation result of resource blocks on a relay station apparatus uplink for each relay station apparatus (510, 520).Type: GrantFiled: June 18, 2009Date of Patent: February 11, 2014Assignee: Sharp Kabushiki KaishaInventors: Takashi Onodera, Toshizo Nogami, Osamu Nakamura, Hiroshi Nakano

Patent number: 8649793Abstract: A method and an arrangement in a radio network node for adapting transmission power of resource elements for demodulation reference signals, referred to as “reference elements” are provided. The radio network node is configured for multiple-input multiple-output transmission, referred to as “MIMO transmission”, to a user equipment. The MIMO transmission comprises at least three layers. Two consecutive subcarriers of a resource block carry at least three reference elements. A first subcarrier of the resource block carries data elements. The radio network node adapts transmission power of said at least three reference elements such that an average transmission power, over said two consecutive subcarriers, of said at least three reference elements is equal to a transmission power, for the first subcarrier, of the data elements for said at least three layers. The radio network node uses the adapted transmission power to transmit, to the user equipment, said at least three reference elements.Type: GrantFiled: November 29, 2010Date of Patent: February 11, 2014Assignee: Telefonaktiebolaget LM Ericsson (publ.)Inventors: Yang Hu, David Astely, George Jongren, Jianfeng Wang
