    摘要： An apparatus and a system for transmitting channel state information acquires channel state information of a channel between a mobile terminal and two or more cooperative base stations. The apparatus quantizes the channel state information separately by using a preset single-cell codebook used for quantizing the channel between the mobile terminal and each one of the two or more cooperative base stations. The apparatus acquires united codeword indexes of the quantized channel state information in the single-cell codebook; and transmits the united codeword indexes of the quantized channel state information in the single-cell codebook.

    摘要： An integrated optically pumped vertical cavity surface emitting laser (VCSEL) is formed by integrating an electrically pumped in-plane semiconductor laser and a vertical cavity surface emitting laser together with a beam steering element formed with the in-plane semiconductor laser. The in-plane semiconductor laser can be a number of different types of in-plane lasers including an edge emitting laser, an in-plane surface emitting laser, or a folded cavity surface emitting laser. The in-plane semiconductor laser optically pumps the VCSEL to cause it to lase. The in-plane semiconductor laser is designed to emit photons of relatively short wavelengths while the VCSEL is designed to emit photons of relatively long wavelengths. The in-plane semiconductor laser and the VCSEL can be coupled together in a number of ways including atomic bonding, wafer bonding, metal bonding, epoxy glue or other well know semiconductor bonding techniques. The beam steering element can be an optical grating or a mirrored surface.
