Publication number: 20140071896Abstract: A wireless communication method and apparatus are disclosed for assigning different phases, (i.e., time periods), to perform data transmissions over designated frequency bands in a cooperative relaying system. In phase 1, a relay station (RS) listens to a wireless transmit/receive unit (WTRU) and successfully receives b information bits. In phase 2, the RS and WTRU cooperatively transmit these b information bits to the destination. These transmissions may be performed in a unicast scheme, wherein a WTRU sends information to a selected RS in phase 1, and the RS forwards the information to a base station (BS) in phase 2. The transmission may also be performed in a multicast scheme, wherein the WTRU sends information to the RS and the BS in phase 1, and the RS transmits a subset the information to the BS in phase 2.Type: ApplicationFiled: November 15, 2013Publication date: March 13, 2014Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Zinan Lin, Eldad M. Zeira, Alexander Reznik, Prabhakar R. Chitrapu, Sana Sfar

Publication number: 20130295948Abstract: Systems and methods are provided for coexistence management service for licensed and unlicensed spectrum sharing. A coexistence system may include a coexistence manager (CM) that may provide resource allocation services for a coexistence enabler (CE). CMs may negotiate with each other to resolve coexistence issues via directly or indirectly through a coexistence discovery and information server (CDIS). A channel may be exclusively used by a CE network. The networks may mitigate interference by avoiding use of the same channels. A channel may be shared by multiple CE networks. In co-channel sharing, the networks may mitigate interference via power management. Bidding processes may be implemented directly via competing CMs, for example via open or silent token auction. Bidding processes among competing CMs may be managed by a third party entity, for example a CDIS, for example via open or silent token auction.Type: ApplicationFiled: May 3, 2013Publication date: November 7, 2013Inventors: Chunxuan Ye, Scott Laughlin, Jean-Louis Gauvreau, Zinan Lin, Martino Freda

Publication number: 20130235793Abstract: A system (1300), method, and apparatus (1900) are provided for a source to choose a partner/relay from at least one candidate(1302) (1303) to transmit at least part of a message from the source (1301) to destination (1304). The choice depends on the channel conditions of the source (1301) and when the source is experiencing poor channel quality to the destination, the source selects the candidate and the modulation modes of the source (1301) and partner/relay (1302) (1303) such that the frame error rate (FER) of the source(1301) is lowered. Otherwise, a modulation mode is selected for each of the source (1301) and the partner/relay (1302) (1303) that most improves the gain in throughput of the source (1301). The present invention applies to modes consisting of binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), and 16-state quadrature amplitude modulation (16-QAM).Type: ApplicationFiled: April 17, 2013Publication date: September 12, 2013Applicants: HIGH TECH CAMPUS 5, KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Zinan Lin, Monisha Ghosh, Elza Erkip
