Patent number: 8346158Abstract: A repeater system combines co-located antennas, an intentional imbalance in signal amplification between downlink and uplink, stability management and an amplification indicator to create a user-installed solution to co-channel interference within cellular systems, in strong signal environments such as elevated locations or high-rise building. The invention may be particularly relevant to cellular systems, such as CDMA, that allow limited imbalance between uplink and downlink path losses, thus enabling the design of an inexpensive repeater with a weaker or non-existent uplink, and which creates moderate signal amplification for selected line-of-sight signals, defeating co-channel interference over a small area. The difference in signal amplification on the downlink and uplink is maintained at a level below the capacity of the system to support imbalance, guaranteeing reliable cellular calls.Type: GrantFiled: April 12, 2012Date of Patent: January 1, 2013Assignee: Bandwidth Wireless Limited Liability CompanyInventor: Frank P.

Patent number: 8335178Abstract: A user terminal (MS) is in wireless communication with a relay station (Access RS), the relay station being in communication with a super-ordinate station such as a base station (MR-BS) such that the user terminal can perform either single-hop communication with the access relay station or multi-hop communication with the super-ordinate station. The system defines at least one specific signal to be used in a bandwidth request for multi-hop and/or single hop communication. When the user terminal needs bandwidth, it issues a bandwidth request to the relay station indicating a single hop or multi-hop communication by including or not including the specific signal. The relay station decides whether or not to issue its own bandwidth request to the super-ordinate station based on the presence or absence of the specific signal.Type: GrantFiled: March 25, 2009Date of Patent: December 18, 2012Assignee: Fujitsu LimitedInventor: Yanling Lu

Patent number: 8331423Abstract: Provided are an apparatus and a method for providing a relay service in a wireless communication system. The apparatus includes a modulator, an encoder, and a transmission unit. The modulator modulates a transmission signal according to a modulation degree. The encoder encodes a modulation symbol provided from the modulator using a convolution code of a ring domain. The transmission unit transmits the signal provided from the encoder to a relay station. The relay station detects a signal where signals received from different transmission ends are added in a real domain, and relays the detected signal, thereby providing a relay service without an additional time resource.Type: GrantFiled: April 1, 2009Date of Patent: December 11, 2012Assignees: Samsung Electronics Co., Ltd., Korea Advanced Institute of Science and TechnologyInventors: Eun-Yong Kim, Ju-Mi Lee, Tak-Ki Yu, Sang-Min Lee, Sung-Soo Kim, Joo-Hwan Chun

Patent number: 8320828Abstract: In a multiuser MIMO system, entire system throughput achieved during retransmission is significantly enhanced. When an interference signal addressed to another user equipment (UE2) 200b has been demodulated successfully, a user equipment (UE1) 200a holds the demodulated data pertaining to the interference signal, and feeds back ACK information about the UE2 and CQI information achieved after elimination of the interference signal to a radio base station (BS) 100. When the UE2 performs retransmission after ended in a receiving failure and when the UE1 has demodulated the interference signal addressed to the UE2 successfully, the BS changes the distribution of communication resources in such a way that communication resources for the UE2 become larger than those for the UE1.Type: GrantFiled: January 25, 2008Date of Patent: November 27, 2012Assignee: Panasonic CorporationInventors: Tomohiro Imai, Masayuki Hoshino, Yasuaki Yuda, Katsuhiko Hiramatsu

Patent number: 8311005Abstract: Methods and systems for reusing macro cell resources in femto cell base stations or relay stations in a non-collaborative manner are disclosed. In addition, orthogonal resource allocation between a macro cell base station and femto cell base stations/relay stations may be dynamically adjusted by considering user-population variance. Moreover, an additional level of spatial reuse by femto cell base stations or relay stations can be provided by employing macro cell user location information.Type: GrantFiled: September 25, 2009Date of Patent: November 13, 2012Assignee: NEC Laboratories America, Inc.Inventors: Karthikeyan Sundaresan, Sampath Rangarajan

Patent number: 8295763Abstract: A system and method of applying a known modification to a signal to enable a determination of a signal received by a first node is received directly from a second node or indirectly through a repeater. The repeater receives a primary signal and creates a secondary signal as a function of the primary signal and a known modification, wherein the known modification identifies the repeater. The primary signal is transmitted and injected with the secondary signal as the first signal to the primary receiver.Type: GrantFiled: November 17, 2011Date of Patent: October 23, 2012Assignee: Andrew LLCInventors: Martin Alles, Joseph P.
