20100084454 | FRICTION PLUG WELDING METHODS AND SYSTEMS - Friction plug welding methods and systems plug a hole extending through a component part from front and back faces thereof. A sacrificial plate having an opening therethrough may be positioned against the back face of the component part with assistance from a restraint part (which is also preferably provided with a space of sufficient dept to receive a terminal end of the male plug) so that the opening is coaxially aligned with the hole to be plugged. Upon advancing a male plug of a plug rod into the hole under friction plug welding conditions, a friction weld region will therefore be formed between the male plug and defining surfaces of both the hole extending through the component part and the opening extending through the sacrificial plate. The plug rod may include an annular shoulder flange which defines a plane parallel to the front face of the component part so that flash flow from the friction welding will be displaced laterally of the hole. The male plug may be frustroconically shaped. An annular arcuate surface may also be provided which joins the male plug to the shoulder flange. | 04-08-2010 |

20150289272 | Method and Apparatus for Resource Allocation Satisfying Multiple Performance Constraints - A low-complexity, efficient Radio Resource Allocation method performed by a base station of a wireless communication network allocates a first plurality of frequency resources among a second plurality of requesting mobile terminals. Each mobile terminal employs a service such that two or more services are represented in the second plurality. The RRA method satisfies all of an exclusivity constraint that each frequency resource is allocated to only one mobile terminal, an adjacency constraint that all frequency resources allocated to any given mobile terminal are contiguous in a frequency domain, and a minimum service requirement constraint that a predetermined number of the mobile terminals employing each service be granted a required data rate. The RRA method comprises two phases: Unconstrained Maximization and Reallocation. In the Unconstrained Maximization phase, frequency resources are iteratively allocated to mobile terminals in an opportunistic way, obeying the exclusivity and adjacency constraints but without concern for the minimum service requirement constraint; the resulting allocation is tested for fulfillment of the minimum service requirement constraint; and one or more mobile terminals are removed from the allocation based on the minimum service requirement constraint test. In the Reallocation phase, frequency resources from one or more mobile terminals that have their required data rate fulfilled are reallocated to one or more mobile terminals that do not have their required data rate fulfilled. | 10-08-2015 |

20120002743 | Statistical Joint Precoding in Multi-Cell, Multi-User MIMO - A network node jointly precodes multi-user (MU) multiple-input multiple-output (MIMO) transmissions simultaneously sent from geographically distributed base stations to a plurality of mobile terminals over associated downlink MU-MIMO channels. The node receives feedback that describes statistics of the downlink MU-MIMO channels, including channel mean and covariance. The node then computes, based on the channel means and covariances, uplink input covariances for the mobile terminals that would collectively maximize a first or second-order approximation of the ergodic capacity of dual uplink MU-MIMO channels, subject to a global transmit power constraint that comprises the sum of individual transmit power constraints for the base stations. Notably, the node also adjusts the uplink input covariances as needed to satisfy the individual transmit power constraints for the base stations, maps the uplink input covariances to corresponding downlink input covariances, and jointly precodes MU-MIMO transmissions sent over the downlink MU-MIMO channels based on those downlink input covariances. | 01-05-2012 |
