Patent number: 9756526Abstract: Techniques are provided for constructing or determining a training sequence as a part of transmission preamble to minimize (or at least reduce) a peak-to-average power ratio (PAPR) at a transmitting node. In one example, a long training field (LTF) sequence of a preamble is determined that combines a set of interpolating sequences with LTF tone values. The LTF tone values may cover at least a portion of bandwidth of a first size, with each of the LTF tone values repeated for different subcarriers. The phases of tones of the LTF sequence may be rotated per bandwidth of the first size and certain tones of the LTF sequence may have a stream of values at pilot locations. For example, the phases of tones of the LTF sequence may be rotated in an effort to reduce PAPR during a transmission of the LTF sequence.Type: GrantFiled: November 11, 2014Date of Patent: September 5, 2017Assignee: QUALCOMM IncorporatedInventors: Lin Yang, Didier Johannes Richard Van Nee, Hemanth Sampath

Patent number: 9735944Abstract: A method and system for minimizing the control overhead in a multi-carrier wireless communication network that utilizes a time-frequency resource is disclosed. In some embodiments, one or more zones in the time-frequency resource are designated for particular applications, such as a zone dedicated for voice-over-IP (VoIP) applications. By grouping applications of a similar type together within a zone, a reduction in the number of bits necessary for mapping a packet stream to a portion of the time-frequency resource can be achieved. In some embodiments, modular coding schemes associated with the packet streams may be selected that further reduce the amount of necessary control information. In some embodiments, packets may be classified for transmission in accordance with application type, QoS parameters, and other properties. In some embodiments, improved control messages may be constructed to facilitate the control process and minimize associated overhead.Type: GrantFiled: May 22, 2015Date of Patent: August 15, 2017Assignee: Neocific, Inc.Inventors: Xiaodong Li, Haiming Huang, Titus Lo, Ruifeng Wang

Patent number: 9713166Abstract: In a heterogeneous cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, the data transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node.Type: GrantFiled: April 25, 2014Date of Patent: July 18, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Stefan Parkvall, David Astely, Erik Dahlman, David Hammarwall, Bengt Lindoff, Stefano Sorrentino, Leif Wilhelmsson

Patent number: 9712272Abstract: Embodiments pertain to systems, methods, and component devices for dynamic non-orthogonal multiple access (NOMA) communications. A first example embodiment includes user equipment (UE) configured to receive a first downlink control indicator (DCI) from an evolved node B (eNB) and process the first subframe as a first higher power NOMA subframe in response to a first power ratio signal. The DCI includes the first power ratio signal for a first NOMA subframe. The UE may then receive, from the eNB, a second DCI, the second DCI comprising a second power ratio signal for a second subframe and process, by the UE, the second subframe as a second lower power NOMA subframe in response to the second power ratio signal. Additional embodiments may further use another DCI with a third power ratio signal to configure the UE to receive orthogonal multiple access (OMA) communications.Type: GrantFiled: December 19, 2014Date of Patent: July 18, 2017Assignee: Intel IP CorporationInventors: Yuan Zhu, Fangze Tu, Qinghua Li, Xiaogang Chen

Patent number: 9706439Abstract: In a mesh network composed of multiple-radio nodes, we assign each radio to one of a plurality of channels, and treat a plurality of links between a pair of nodes as one logical link (bonded link). In some embodiments, the routing protocol is adapted to view each bonded link as one link having a combination of at least some of the properties of the constituent physical links. Traffic sent along a path is dynamically load balanced between the interfaces at each intermediate node based on the current utilization of each interface. In at least some embodiments, route discovery packets record the metrics of each component link of the bonded links leaving a node, but only one route discovery packet per pair of nodes is forwarded, reducing the route discovery packet traffic compared to if each route discovery packet were forwarded over each component link between the pair of nodes.Type: GrantFiled: May 10, 2014Date of Patent: July 11, 2017Assignee: Firetide, Inc.Inventors: Sachin Kanodia, Mohan Natarajan, Jorjeta Gueorguieva Jetcheva

Patent number: 9699693Abstract: An architecture is described that can provide enhancement with respect to circuit switched fall back. In particular, the architecture can reduce the signaling and delay of conventional systems that are necessitated by establishing a radio resource control connection prior to establishing the circuit switched fall back connection. For example, when user equipment is not in a radio resource control connected state at the time of a circuit switched fall back call, the radio resource control connection can be at least partially avoided by responding to a radio resource control connection request message with a radio resource control connection reject message that includes target cell reselection information.Type: GrantFiled: November 12, 2014Date of Patent: July 4, 2017Assignee: AT&T MOBILITY II LLCInventors: Weidong Hu, Inderpreet Singh Ahluwalia, Yung Shirley Choi-Grogan
