| 20160007401 | WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, TRANSMISSION DEVICE, CONTROL METHOD, AND RECORDING MEDIUM - A wireless communication system includes a transmission device, a relay device, and a reception device and is configured to execute direct communication of directly transmitting a wireless signal from the transmission device to the reception device without routing through the relay device and indirect communication of indirectly transmitting a wireless signal from the transmission device to the reception device through the relay device. The wireless communication system includes a controller configured to estimate a disconnection continuation time that is a time during which the direct communication is not executable in a case where the direct communication is not executable while the direct communication is repeatedly executed, continue to execute the direct communication when the disconnection continuation time is shorter than a threshold time, and execute the indirect communication when the disconnection continuation time is longer than the threshold time. | 01-07-2016 |
| 20160020838 | ACTIVE MIMO ANTENNA CONFIGURATION FOR MAXIMIZING THROUGHPUT IN MOBILE DEVICES - An active antenna system and algorithm is proposed that provides for dynamic tuning and optimization of antenna system parameters for a MIMO system that will provide for greater throughput. As one or multiple antennas are loaded or de-tuned due to environmental changes, corrections to correlation and/or isolation are made by tuning the active antenna. A null-steering technique is implemented to alter the near-field and far-field characteristics to aid in modifying correlation and isolation in the multi-antenna system. | 01-21-2016 |

| 20160066204 | USER EQUIPMENT ASSISTANCE FOR INTERFERENCE MITIGATION IN UNLICENSED FREQUENCY BANDS - A first base station selects a subset of channels of an unlicensed frequency band based on indications of energy received over the channels. The first base station transmits one or more messages instructing user equipment to monitor the subset of channels and report information indicating whether at least one second base station is transmitting over the subset of channels. User equipment monitors the subset of channels of the unlicensed frequency band in response to receiving the one or more messages from a first base station indicating the subset of channels. The user equipment transmits one or more messages including information indicating whether one or more second base stations are transmitting over the subset of channels. | 03-03-2016 |
