The method may further include determining a cost of granting the request, the cost being based at least in part on a cost to a lending cell within the first wireless network from which the spectral resources will be borrowed and a cost to neighboring cells of the lending cell. The method may further include lending the spectral resources to the second wireless node based at least in part on the determined cost of granting the request.Type: GrantFiled: September 19, 2008Date of Patent: October 21, 2014Assignee: Nokia CorporationInventors: Carl Simon Wijting, Klaus Doppler

Patent number: 8867563Abstract: Embodiments of the present invention provide for content optimization of a physical layer preamble. In one embodiment of the invention, a method for encapsulating a payload for transmission through a network is disclosed. The method comprises the step of programming a legacy physical layer length value in a legacy physical layer preamble. The legacy physical layer preamble is configured such that it can be received by any legacy stations that may be on the network, and such that a separate physical layer length value can be derived from the legacy physical layer preamble. Using such a system, content optimization of a physical layer preamble is provided.Type: GrantFiled: August 26, 2010Date of Patent: October 21, 2014Assignee: QUALCOMM IncorporatedInventor: James Cho

Patent number: 8867656Abstract: When a determination is made that communication by an SM scheme is suitable, a setting unit performs switching from a communication level by an STC scheme to the communication level by the SM scheme, between the communication level at a first level of MCS by the space-time coding scheme and the communication level at a second level of MCS by the SM scheme. When a determination is made that communication by the SM scheme is unsuitable, the setting unit performs switching from the communication level by the STC scheme to the communication level by the spatial multiplexing scheme, between the communication level at a third level of MCS, which is higher than the first level, by the space-time coding scheme and a fourth level of the modulation scheme and the coding rate, which is higher than the second level, by the SM scheme.Type: GrantFiled: December 14, 2011Date of Patent: October 21, 2014Assignee: KYOCERA CorporationInventor: Takeo Miyata

Patent number: 8861543Abstract: A communication device and methods are disclosed. A first throughput is calculated when a current modulation scheme and a current encoding rate is changed, and a second throughput is calculated when a current retransmission unit is changed. The current modulation scheme and the current encoding rate are changed to provide a changed modulation scheme and a changed encoding rate, if the first throughput is greater than or equal to the second throughput when prescribed conditions are met. The current retransmission unit is changed to provide a changed retransmission unit, if the first throughput is less than the second throughput. Information is transmitted to a communication device of a communication partner based on the changed modulation scheme, the changed encoding rate, and the changed retransmission unit.Type: GrantFiled: January 27, 2012Date of Patent: October 14, 2014Assignee: Kyocera CorporationInventor: Yoshizo Sato

Patent number: 8854993Abstract: A system for facilitating interaction with one or more radio modules incorporated within an apparatus. An interface may be provided to supply parameters usable by one or more radio modules for regulating communication. In at least one example configuration, the interface may receive information pertaining to one or more communication flows, may utilize the communication flow information to determine operational conditions for managing the one or more communication flows, and may formulate parameters for controlling one or more radio modules based on the operational condition information. These formulated parameters may then be provided to the one or more radio modules in the apparatus.Type: GrantFiled: December 29, 2009Date of Patent: October 7, 2014Assignee: Nokia CorporationInventors: Ville Pernu, Jussi Tuomas Benjamin Ratilainen

Patent number: 8856347Abstract: A method, system and article of manufacture are disclosed for selecting a channel instance for connecting a client application with a server application in a multi-channel computer system. In this computer system, when a new channel instance is used to connect one of the client applications with one of the server applications, defined channel instance information is established for the channel instance. The method of this invention comprises the steps of when a new application connection request is made, locking existing channel instance information; and after said locking, scanning through a list of channel instance connections for one of the channel instances that is a candidate channel instance for that new application connection request. The method comprises the further steps of, in response to finding a candidate channel instance, determining whether the candidate channel instance is suitable for the new application connection request.Type: GrantFiled: October 9, 2008Date of Patent: October 7, 2014Assignee: International Business Machines CorporationInventors: Peter A. Broadhurst, Paul G. Clarke, Michael Horan, Jitendra K. A. Patel
