摘要： A unified open loop single-user/multiple-user multiple-input-multiple-output (MIMO) system and method are disclosed. The system and method operate without use of channel state information feedback. Instead, the method utilizes channel quality indicator feedback to schedule users to spatial resource blocks. Both symmetric multi-user MIMO schemes (like 2×2 and 4×4) and asymmetric multi-user MIMO schemes are considered. CQI feedback and reduction proposals are also introduced. The method may be used in a proposed network topology.

摘要： A beam selection method in open loop MU-MIMO is disclosed, for an asymmetric antenna configuration. The proposed beam selection method employs limited feedback, as compared with single-user closed-loop MIMO and multiple-user closed-loop MIMO, in which the base station requires channel state information (CSI). The multi-user MIMO beam selection method selects the portion of beams from candidate beams for data transmission, meaning that the base station is training M beams. From this, the subscriber station selects N beams from the total M beams, with N≦M.

摘要： The invention relates to a kit, a device and a method for detecting the copy number of fetal chromosomes and tumor cell chromosomes. The method for detecting the copy number of fetal chromosomes or tumor cell chromosomes of the invention includes the following steps: collecting maternal plasma or plasma of tumor patient; separating the plasma from blood cells in blood; preparing Deoxyribonucleic Acids (DNA) in the plasma into a sequencing library; sequencing the DNA sequencing library; comparing a sequencing result with a genomic sequence map to determine which chromosome the DNA sequence comes from and the length of each DNA sequence; and calculating the ratio of the DNA segments from the chromosomes to be detected to all DNA segments in the same sample by a sequencing and comparison result of DNA, correcting the ratio according to a GC content of the DNA segments from the chromosomes to be detected, and calculating the variation of the corrected ratio of the DNA segments from the chromosomes to be detected in a sample to be detected, and determining the copy number of the chromosomes to be detected according to degree of variation.
