The process also includes receiving spectrum usage information by the primary wireless system from the second wireless system. The process further includes determining by the primary wireless system whether the second wireless system complies with spectrum sharing band conditions between the primary wireless system and the second wireless system.Type: GrantFiled: June 3, 2015Date of Patent: January 14, 2020Assignee: The Aerospace CorporationInventors: Laurence F. Zapanta, Peter G. Kim, Beau Backus, James P. Roberts

Patent number: 10470112Abstract: A method of wireless communication includes configuring a small cell with activation parameters. The activation parameters include a new carrier type having a reduced periodicity. The method also includes configuring a UE with time restricted measurements. The time restricted measurements correspond to the new carrier type and the reduced periodicity. The method further includes receiving small cell signal measurements from the UE and initiating an activation sequence in response to the small cell signal measurements.Type: GrantFiled: June 23, 2015Date of Patent: November 5, 2019Assignee: QUALCOMM IncorporatedInventors: Aleksandar Damnjanovic, Durga Prasad Malladi, Siddhartha Mallik, Naga Bhushan, Yongbin Wei, Gavin Bernard Horn

Patent number: 10462810Abstract: Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.Type: GrantFiled: October 27, 2017Date of Patent: October 29, 2019Assignee: Intel CorporationInventors: Aris Papasakellariou, Timothy M.

Patent number: 10355895Abstract: A distributed radio frequency communication system facilitates communication between a wireless terminal and a core network. The system includes a remote radio unit (RRU) coupled to at least one antenna to communicate with the wireless terminal. The RRU includes electronic circuitry to perform at least a first portion of a first-level protocol of a radio access network (RAN) for communicating between the wireless terminal and the core network. The system also includes a baseband unit (BBU) coupled to the core network, and configured to perform at least a second-level protocol of the RAN. A fronthaul link is coupled to the BBU and the RRU. The fronthaul link utilizes an adaptive fronthaul protocol for communication between the BBU and the RRU. The adaptive fronthaul protocol has provisions for adapting to conditions of the fronthaul link and radio network by changing the way data is communicated over the fronthaul link.Type: GrantFiled: March 11, 2016Date of Patent: July 16, 2019Inventors: Alan Barbieri, Dario Fertonani

Patent number: 10356807Abstract: Techniques are described for wireless communication. A first method may include inserting, in a first transmission using a first radio access technology (RAT), a channel occupancy identifier for a second transmission using a second RAT. The first method may also include transmitting the first transmission having the channel occupancy identifier over an unlicensed radio frequency spectrum band. A second method may include receiving, at a receiver operated using a first RAT, a channel occupancy identifier for a transmission using a second RAT. The channel occupancy identifier may be received over an unlicensed radio frequency spectrum band. The second method may also include decoding the channel occupancy identifier to identify a backoff period, and refraining from accessing the unlicensed radio frequency spectrum band using the first RAT based at least in part on the identified backoff period.Type: GrantFiled: July 6, 2015Date of Patent: July 16, 2019Assignee: QUALCOMM IncorporatedInventors: Srinivas Yerramalli, Aleksandar Damnjanovic, Kiran Kumar Somasundaram, Tao Luo, Onkar Jayant Dabeer, Durga Prasad Malladi, Naga Bhushan, Yongbin Wei, Peter Gaal, Wanshi Chen, Anastasios Stamoulis, Hao Xu, Xiaoxia Zhang

Patent number: 10349429Abstract: A system and method for frequency redirection in a communication system. In one embodiment, an apparatus accesses a communication system using first system information associated with a first frequency providing a first radio measurement. The apparatus receives an instruction to evaluate at least one frequency, and performs a second radio measurement over a second frequency without reading second system information associated with the second frequency. The apparatus accesses the communication system using the second system information associated with the second frequency when the second radio measurement exceeds a threshold, and performs a third radio measurement over a third frequency when the second radio measurement is less than or equal to the threshold and without reading third system information associated with the third frequency.Type: GrantFiled: December 17, 2017Date of Patent: July 9, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Badawi Yamine, Tomas Hedberg

Patent number: 10327156Abstract: A resource allocation method according to the present invention may comprise the steps of: allocating a signal of an external resource to a predetermined resource according to a preconfigured resource allocation frame structure by a first base station governing a first cell; allocating a signal of an internal resource to the resource according to the resource allocation frame structure by a second base station governing a second cell adjacent to the first cell; and frequency-hopping the signal of the internal resource by the second base station when the signal of the internal resource overlaps the signal of the external resource. Accordingly, proposed is a resource allocation method capable of stably receiving a signal even when a terminal moving in a dense small cell structure is located at a cell edge, that is, an inter-cell boundary area.Type: GrantFiled: July 15, 2014Date of Patent: June 18, 2019Assignee: LG ELECTRONICS INC.Inventors: Ilmu Byun, Hyunsoo Ko, Kungmin Park, Heejeong Cho, Hyeyoung Choi
