Hidden channel hopping sequence based on swapping sequence offsets using allocated swapping schedule
Patent number: 9673856Abstract: In one embodiment, a method comprises: allocating, to each network device in a time slotted channel hopping network, a corresponding swapping schedule that maps the network device to different unique sequence offsets for different timeslots allocated to the corresponding network device, each unique sequence offset identifying a corresponding shifted position in a prescribed repeating channel hopping sequence relative to an epochal start of a linearly increasing timeslot value; and causing each network device to transmit according to its corresponding swapping schedule, enabling a channel hopping sequence of each network device to be undetectable relative to the prescribed repeating channel hopping sequence.Type: GrantFiled: November 24, 2015Date of Patent: June 6, 2017Assignee: Cisco Technology, Inc.Inventors: Pascal Thubert, Patrick Wetterwald, Jean-Philippe Vasseur, Eric Michel Levy-Abegnoli -
Patent number: 9660765Abstract: Low latency wireless communication applications require highly dynamic allocation of resources. Providing allocation information on a highly dynamic basis increases the overhead of control signaling for allocation. A technique known as blind decoding is used to reduce the control signaling overhead for allocation information. However, blind decoding may occasionally lead to invalid detection of allocation messages which in turn may lead to a number of problems such as wasted bandwidth, increased power consumption, reduced throughput, etc. A method and apparatus are disclosed that detect the invalid allocation messages by maintaining a record of previously received allocation messages and using it to check the validity of the newly received allocation messages.Type: GrantFiled: July 13, 2015Date of Patent: May 23, 2017Assignee: MBIT WIRELESS, INC.Inventors: Keerthivasan Suresh, Kirubakaran Ponnurangam, Krishnavelan Sivaraman

Patent number: 9660744Abstract: In one embodiment, a method includes receiving transmission segments from at least one device over a plurality of channels pursuant to a channel-switching schedule, the channel-switching schedule comprising an iteratively-repeated channel sequence. The iteratively-repeated channel sequence comprises a plurality of channels, the channel-switching schedule specifying an assigned transmission duration for each channel. In addition, the method includes, for at least one channel of the plurality of channels, detecting interference during a time segment of the assigned transmission duration, the time segment comprising at least one of a beginning portion and an ending portion of the assigned transmission duration. Further, the method includes responsive to the detected interference, determining to shift, by a specified quantity of time, a future channel switch indicated by the iteratively-repeated channel sequence.Type: GrantFiled: January 13, 2015Date of Patent: May 23, 2017Assignee: Enforcement Video, LLCInventor: A.

Patent number: 9660698Abstract: The present invention relates to a wireless communication arrangement comprising a node and a leaky cable running between a first and second converter arrangement. The first converter arrangement connects a first downlink signal and a second downlink signal to the cable, and converts the second downlink signal from a first frequency to a second frequency. The cable's other end is connected to the second converter arrangement which converts the second downlink signal from the second frequency to the first frequency. The second converter arrangement also converts a first uplink signal from a third frequency to a fourth frequency. The first converter arrangement receives the converted first uplink signal from the second converter arrangement and converts it from the fourth frequency to the third frequency. The first frequency is separated from the second frequency, and the third frequency is separated from the fourth frequency.Type: GrantFiled: May 29, 2013Date of Patent: May 23, 2017Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Anders Derneryd, Andreas Nilsson

Patent number: 9603129Abstract: A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. Currently active CPEs request bandwidth using unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE.Type: GrantFiled: January 31, 2014Date of Patent: March 21, 2017Assignee: Wi-LAN, Inc.Inventors: Kenneth L.

Patent number: 9537613Abstract: Systems and methodologies are described that facilitate identifying resources upon which an acknowledgment can be sent or received in a wireless communication environment that leverages coordinated multi-point (CoMP). The resources can be identified based upon a criterion that can be identifiable to a non-anchor cell base station (as well as an anchor cell base station, a mobile device, etc.). The criterion can be an identifier corresponding to a mobile device, where the identifier maps to a predetermined set of resources. Examples of the identifier can include a media access control identifier (MACID), a cell radio network temporary identifier (C-RNTI), a short C-RNTI, etc. Further, the criterion can be physical resources corresponding to a transmission, where the acknowledgment is responsive to the transmission. Moreover, the acknowledgment can be sent or received in connection with a cooperation technique (e.g.Type: GrantFiled: October 15, 2009Date of Patent: January 3, 2017Assignee: QUALCOMM IncorporatedInventors: Ravi Palanki, Alexei Y.
