Abstract: An information transmission method includes a step of receiving first downlink control information. The first downlink control information includes frequency hopping indication information of a physical uplink control channel (PUCCH) and/or transmission mode indication information of the PUCCH, or the first downlink control information is downlink control information scrambled by a first radio network temporary identifier. The method further includes performing data transmission based on the downlink control information. Based on the first downlink control information, the terminal device can perform frequency hopping to obtain a frequency diversity gain and to improve flexibility. Also transmission may be repeated to improve transmission performance, and a frequency resource may be adjusted to achieve load balancing or obtain a frequency diversity gain.

Abstract: The invention discloses a three-dimensional atrial septal puncture method including positioning the heart from a body surface by a three-dimensional projection positioning method and displaying interventional instruments by the three-dimensional system and guiding the same into a heart cavity. The method also includes constructing a right atrium three-dimensional model by delivering a catheter with a positioning device to the right atrium and reconstructing and fusing pre-operative image data by the three-dimensional system. The method also includes setting parameters, connecting an interventional operating device with a pressure sensor tail wire and an electrode tail wire, and displaying a guidewire or a puncture needle. The method includes delivering and positioning the long sheath, analyzing and marking the fossa ovalis position by a structure and potential method.
