Abstract: This application provides a UCI sending and receiving method and a communications apparatus. In the method, an association relationship between a PUCCH and a PUSCH is established, so that when resources of the PUSCH and the PUCCH overlap, a terminal device can determine UCI on which PUCCHs can be transmitted by multiplexing the resource of the PUSCH. A network device may receive the UCI on the PUSCH. Because the network device may know in advance which PUCCHs and PUSCHs are sent to the network device, the network device can demodulate and decode a signal on the received PUSCHs, to successfully obtain UCI. The network device can make a proper decision based on the UCI.

Abstract: This application provides a channel measurement method and a communications apparatus. The method includes: A terminal device generates first indication information and sends the first indication information to a network device, where the first indication information is determined based on received precoded reference signals of P ports and is used to indicate Q ports in the P ports; the P ports correspond to P angle-delay pairs; each angle-delay pair includes one angle vector and one delay vector; the precoded reference signal of each of the P ports is obtained by precoding a reference signal based on one angle vector and one delay vector; and the Q ports correspond to Q angle-delay pairs in the P angle-delay pairs.

Abstract: Embodiments of the disclosure include methods of prenatal testing using non-invasive means that identify single gene disorders. In specific embodiments the methods are non-invasive and employ tagging circulating cell-free fetal DNA from the biological mother with particular adaptors that employ unique barcodes, followed by steps to enrich targets and steps for thorough sequencing.

Abstract: The disclosure concerns methods and compositions for obtaining reliable copy numbers of highly homologous gene(s) using next generation sequencing. The methods determine whether or not an individual is a carrier of an autosomal recessive gene mutation using a determination of copy number of two genes, in specific embodiments. In at least some cases, an individual is identified whether or not he or she is a carrier or affected for a genetic defect in SMN1, wherein the defect is associated with spinal muscular atrophy.
