20160165460 | Self-care self-tuning wireless communication system - A customer self-service tuning system assists a mobile device user in adjusting his network settings and device configuration. Device, network and performance metrics are stored for a population. Over time all of these suggest changes in the device or network that change measured performance. The potential improvement(s) are presented to the user for selection. Performance measurements are taken and the user can choose to go forward with the new configuration or to revert. Each time a user requests self-care service, a new cohort is extracted from the then current overall population and analyzed for similarity to the user at that point in time. Each time an improvement is selected, the history of device states and network states is augmented. Identified variances are transformed into an action plan specific to a user and implemented on the device or network upon concurrence. | 06-09-2016 |

20160192226 | COMMUNICATIONS TERMINAL WITH LINEAR OPERATING POINT DETERMINATION - It is determined, e.g., in a communications terminal, that a test triggering event has occurred. A test is initiated based on the determination that the test triggering event has occurred. One or more transmissions are transmitted at one or more respective specified power levels. Measurement data is received from a remote measurement unit indicating respective received power levels of the one or more transmissions by the remote measurement unit. Based on the measurement data, a maximum transmit power level is determined. | 06-30-2016 |
20160192229 | CHANNEL MEASUREMENT METHOD, TERMINAL DEVICE, AND BASE STATION - The present invention discloses a channel measurement method, including: acquiring first channel information, where the first channel information includes one or more of the following information: first CSI of a first channel, and first measurement configuration information used for measuring the first channel; receiving second measurement configuration information sent by a base station and used for measuring a second channel, and measuring the second channel according to the first channel information and the second measurement configuration information, to obtain second CSI. The present invention further discloses a terminal device and a base station. Subsets of a CSI-RS pattern of a whole antenna and a CSI-RS pattern of a partial antenna are configured and feedbacks to quality information of a whole channel and quality information of a partial channel are combined, so that not only signaling is reduced but also feedback accuracy is improved. | 06-30-2016 |
