Der eNB überwacht Parameter von Bandbreiten in dem unlizenzierten Spektrum, wenn mindestens einer der Parameter eine Änderung der Verfügbarkeit für eine ausgewählte der Bandbreiten anzeigt, der eNB erzeugt einen Steueranzeiger, der die Änderung der Verfügbarkeit auf die Bandbreite definiert, und strahlt den Steuerindikator an die UE aus, wobei der Steueranzeiger eine Modifikation in einem Sendeempfänger der UE beeinflusst, welcher der Bandbreite zugeordnet ist.

Light-emitting device and display panel

A light-emitting device and a display panel. A light-emitting color of the light-emitting device is a primary color of either red or green, and the light-emitting device includes: a light-emitting layer with a host material; a compensation layer for carrying holes and disposed on a hole injection side of the light-emitting layer; the light-emitting device has a starting state and an operating state, and a starting voltage of the light-emitting device in the starting state is lower than an operating voltage of the light-emitting device in the operating state; in the starting state, there is a first activation energy difference value ΔEa1 between activation energies of the host material and the compensation layer, and the first activation energy difference value ΔEa1<0 eV.

Apparatus and methods for synchronization recovery in a hybrid network

Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected "tune-away" period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.

Automatic improvement of software applications

A computer-implemented method including tracking data describing a new population of users of a software application including different graphical user interfaces (GUIs). The method also includes generating a distribution by mapping the data to lookalike cohorts. The method also includes extracting, using a random sampling algorithm, samples from the distribution. The method also includes generating, from the samples, a normal distribution of predicted long term values of the new population of users. The method also includes selecting an expected long term value from the normal distribution. The method also includes generating, from the normal distribution, an estimated distribution, around the expected long term value, of estimated long-term values for the new population. The method also includes selecting, using the expected long term value and the estimated distribution, a selected GUI from among the different GUIs. The method also includes modifying the software application by presenting the selected GUI.

Multi-device collaboration method, electronic device, and multi-device collaboration system

A distributed system is run in a device in the method. The distributed system includes a system service, a first-type service located at an upper layer of the system service, and a second-type service located at an upper layer of the first-type service and having an interface display function. Both the first-type service and the second-type service are atomic services. A second device migrates a teaching video to a first device, and the first device plays the teaching video. A second-type service in the first device may call a first-type service in another device, to control the another device to capture a user action picture video, process the teaching video and the user action picture video to obtain teaching guidance, and play the teaching guidance.
