摘要： The present invention discloses a node for transmission mode switching for downlink transmission in a downlink channel (100), comprising: a configuring unit (110) adapted to configure an initial transmission mode for the downlink transmission as a default transmission mode; a deriving unit (120) adapted to derive channel quality metric (CQM) of the downlink channel; a first determining unit (130) adapted to determine a first predefined threshold on the basis of link level simulation of a first transmission mode and a second transmission mode; and a first switching unit (140) adapted to switch the transmission mode from the initial transmission mode to the first transmission mode or the second transmission mode on the basis of the CQM and the first predefined threshold. The present invention provides a simple, direct and efficient approach for transmission mode switching for downlink transmission in a downlink channel on the basis of available feedback from UE (or other kinds of terminals if appropriate) and/or link adaptation decisions from eNB (or other kinds of base stations if appropriate), provides high peak rate while maintaining cell coverage, and provides a proprietary solution without any impact on protocol/standard or UE implementation.

摘要： When a high SIR can be achieved for downlink data transmission, for example in a MIMO system, or when higher order modulation, such as 64 QAM, can be used, it is desired to measure the instantaneous downlink channel quality indicator (CQI), and report the measured CQI to the network using the same number of bits as when a lower SIR can be achieved. In order to do this, a true CQI is derived based upon at least one network controlled parameter and a measured channel quality parameter; and the true CQI value is scaled to a new CQI value such that the new CQI will fall within a specified range of CQI values; so that the new CQI achieved by scaling the derived CQI value can be reported with every CQI value over the entire reporting range requiring the same number of bits.

摘要： A selective high intensity ultrasonic foaming technique is described to fabricate porous polymers for biomedical applications. Process variables, including ultrasound power, scanning speed, and gas concentration have an affect on pore size. Pore size can be controlled with the scanning speed of the ultrasound insonation and interconnected porous structures could be obtained using a partially saturated polymers. A gas concentration range of 3-5% by weight creates interconnected open-celled porous structures. The selective high intensity ultrasonic foaming method can be used on biocompatible polymers so as not to introduce any organic solvents. The method has use in cell related biomedical applications such as studying cell growth behaviors by providing a porous environment with varying topological features.
