The invention relates to a vertical vibration isolation system of single freedom and ultra-low frequency, comprising a mass block, a middle mass block, a zero point generator, a zero stiffness apparatus and a stiffness base. The zero stiffness apparatus invents the dynamic stiffness values of the system at a low cost, which greatly decreases the natural frequency of the system and realizes the passive vibration isolation within the range of ultra-low frequency. The zero point generator reduces the vibration transmissibility in the range of the ultra-low frequency and improves the efficiency ofvibration isolation; otherwise, the parameters of the zero point generator can be changed to regulate the system vibration transmissibility according to the actual amplitude and frequency requirements of the vibration isolation. The existing relationship between the zero point generator and the zero stiffness apparatus is: the zero stiffness apparatus decreases the dynamic stiffness value and also brings down the zero value of the zero point generator III and realizes zero within the range of ultra-low frequency.

The invention is used for improving the transmission efficiency of Iub interface and uses SDTP protocol to make data transmission of Iub interface. For each FP layer connection, the bottom layer needs to provide two links; when the length of FP frame is less than M bytes, one of said links maps the IP address and UDP port number to the SDTP node number and MUX-AL port number; when the length of FP frame is more than M bytes, another link directly uses IP address and UDP to package and adopt D-AL to bear.

The present invention discloses a method for transmitting uplink control signaling in a Physical Uplink Shared Channel (PUSCH). The method includes: when two transport blocks / codewords are transmitted in the PUSCH, mapping uplink control signaling to the layer corresponding to one of the two transport blocks / codewords to transmit. The present invention also discloses an apparatus for transmitting uplink control signaling in the PUSCH. The apparatus includes: a mapping unit, used for mapping uplink control signaling to the layer corresponding to one of two transport blocks / codewords when the two transport blocks / codewords are transmitted in the PUSCH; and a transmission unit, used for transmitting the uplink control signaling.
