摘要： A multiuser downlink multiple-input multiple-output (MIMO) system with limited channel information feedback includes an error-free channel vector quantization scheme. Each user has multiple antennas, and the base station includes a matching number of antennas. Each MIMO channel is measured at the terminus end of a corresponding user, and used to obtain the channel state information at the receiver (CSIR). A few data bits of CSIR information are feed back to the base station through the limited feedback channels. The base station collects all these CSIR feedback data bits into a CSI at the transmitter (CSIT). The CSIT is used to determine which users are served, and how to configure a corresponding multi-user precoder. The user data channels will later all be transmitted through such precoder. A codebook of channel quantization vectors is pre-defined and distributed amongst the base station and all the users.

摘要： A sensor scheme combining nano-photonics and nano-fluidics on a single platform through the use of free-standing photonic crystals is described. By harnessing nano-scale openings, both fluidics and light can be manipulated at sub-wavelength scales. The convective flow is actively steered through the nanohole openings for effective delivery of the analytes to the sensor surface, and refractive index changes are detected in aqueous solutions. Systems and methods using cross-polarization measurements to further improve the detection limit by increasing the signal-to-noise ratio are also described.

摘要： A buffer information report can be sent to a system station from a node for relaying communications between at least one user station and the system station. The report is generated based on a report format used for uplink reporting by a user station. An indication is also sent to the system station that the node for relaying has different buffering capabilities than the user station. At the system station the buffering capabilities of the node for relaying can be determined based on the buffer information report and the indication. Communications between the system station and the node for relaying can then be controlled accordingly.
