20150017944 | Flexible Device Upgrade Plan - Described herein are techniques for receiving, by a telecommunication service provider, used telecommunication devices from a plurality of subscribers of the telecommunication service provider. The used telecommunication devices may each have been purchased with an installment plan on which a balance is owed, and different balances may be owed on different ones of the used telecommunication devices. In exchange for the used telecommunication devices, the telecommunication service provider may pay off up to at least part of each of the balances. Further, prior to paying off the balances, the telecommunication service provider may obtain identifiers for the used telecommunication devices and verify that the obtained identifier for each used telecommunication device matches an identifier that is associated with one of the subscribers and is stored in a data store of the telecommunication service provider. | 01-15-2015 |

20140106695 | Antenna Clustering For Multi-Antenna Aperture Selection - The specification and drawings present a new method, apparatus and software related product for antenna clustering for multi-antenna aperture selection (MAAS), e.g., in LTE wireless systems, using multi-core DSP processing with sub-optimum selection of N out of M of antenna signals and minimizing the performance degradation due to the sub-optimal antenna/antenna signal selection. Assigning each DSP core (machine) to N/K antennas (i.e., to antenna signals) having a similar property (e.g., polarization) and a same tier, the selection of N out of M using a predefined criterion (e.g., best SINR) is reduced to selecting N/K out of M/K which reduces the computation complexity by a factor of K, where K is a number of the DSP cores. | 04-17-2014 |

20100166098 | METHOD AND APPARATUS FOR ANTENNA SELECTION AND POWER CONTROL IN A MULTIPLE INPUT MULTIPLE OUTPUT WIRELESS COMMUNICATION SYSTEM - A MIMO base station is provided that includes a multi-channel transmitter having an input Fourier Transform Matrix (FTM) and an output FTM that are each coupled to an intervening signal processing section having multiple radio frequency (RF) amplifiers. A signal applied to an input port of the input FTM is distributed to all RF amplifiers of the transmitter by the input FTM and then is recombined by the output FTM such that the signal is routed to a single antenna of the multiple antennas of an antenna array. Thus, for both MIMO and non-MIMO transmissions, all RF amplifiers are used to amplify each input signal, but the non-MIMO transmission signal then is recombined such that only a single transmit antenna then is used to transmit the signal. The base station further provides antenna selection for a single antenna transmission and gain allocation among the multiple antennas for a MIMO transmission. | 07-01-2010 |
