摘要： The invention discloses a beamforming method for polarized antenna array consisting of a plurality of antenna elements, applied to single layer beamforming or dual layer beamforming, which includes the steps: determining (201) first beamforming weights for phase compensation among the antenna elements within each polarization direction; determining (202) second beamforming weights for phase compensation between equivalent channels of two polarization directions; and calculating (203) hybrid beamforming weights as product of the first beamforming weights and the second beamforming weights. A beamforming apparatus for polarized antenna array is also provided in the invention as well as a radio communication device and a system thereof. With the invention, the single-layer and dual-layer beamforming weights are determined for the cross-polarized antenna array without requiring full channel knowledge or the aid of PMI.

摘要： A method of and system for time-division-based channel collision collaboration in a wireless communication system including at least two Wireless Regional Area Networks (WRANs) with overlapping service areas that employ dynamic frequency hopping is provided. The method includes performing, by at least one Consumer Premise Equipment (CPE) located in an overlapping portion of service areas of at least two WRANs, spectrum sensing and feeding idle channel information back to respective Base Stations (BSs) of the at least two WRANs, broadcasting, by each of the at least two WRANs, a pre-occupation announcement message for a qualified idle channel, and determining, by a WRAN with the highest priority of the at least two WRANs, a time resource allocation for WRANs in a channel collision state of the at least two WRANs. The method addresses problems, such as a large delay and impaired wireless access due to an absence of an idle channel for adjacent WRANs, may be avoided, while the WRANs may maintain their QoSs. Therefore, transmission power of a WRAN during non-operation period may be conserved.

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 micromixer is fabricated using a selective high intensity focused ultrasound foaming technique. The micromixer (300) employs a 3D porous region (302) for effective mixing. The 3D porous micromixer can achieve sufficient mixing results with a short mixing length for flows with a Reynolds number as low as 0.1. The fabrication process of the micromixer is rapid, low-cost, and biocompatible. The pore size of the micromixer can be controlled by adjusting the selective high intensity focused ultrasound foaming parameters. The micromixer has potential for use in lab-on-a-chip and micro-total- analysis devices.
