Title: Method and apparatus for processing reference signal
Inventor: WEI YI
IPC: H04J13/00
Filed: 2020-07-31
Abstract: Provided in embodiments of the present application are a method and apparatus for processing a reference signal. The method comprises: determining a base sequence on the basis of a first Zadoff-Chu sequence that has a length of N zc ; according to the base sequence, generating a reference signal sequence that has a length of M; and then generating a reference signal according to the reference signal sequence and sending same to a receiving end. The base sequence is one of L candidate base sequences, wherein L≥31 and L is an integer; and the value of N zc  is a prime number in the set [97,431]. In the embodiments of the present application, since the Zadoff-Chu sequence used for generating the candidate base sequence is longer, the number of candidate base sequences increases, so that the number of base sequences available in one cell may be increased, thus satisfying the demand for a large number of terminals in the one cell to require more base sequences in a scenario in which the number of terminals in the cell has greatly increased, and the terminals in the cell do not need to make different terminals take turns sending uplink reference signals by means of a time division manner, which ensures the performance of a system.

Title: Firecracker device
Inventor: ZHOU XIAOWEN
IPC: B01F23/10
Filed: 2020-07-31
Abstract: The present invention relates to a firecracker device, comprising: a gas supply assembly, used to provide combustible gas; a firecracker tube assembly, having a combustion chamber formed therein to allow the combustible gas to burn; and a mixing tube, connected between the gas supply assembly and the firecracker tube assembly. A mixing chamber communicating between the gas supply assembly and the combustion chamber is formed in the mixing tube, and an air suction port communicating the mixing chamber to the exterior is provided on the mixing tube. When the combustible gas provided by the gas supply assembly flows through the mixing chamber at a high speed, negative pressure is generated in the mixing chamber, and exterior air enters the mixing chamber by means of the air suction port and mixes with the combustible gas. Finally, a combustible gas flow mixed with the exterior air enters the combustion chamber, and combusts and explodes in the combustion chamber to produce detonation, so as to achieve the effect of simulating the sound of firecrackers. The firecracker device needs only one gas supply assembly to provide combustible gas. When the combustible gas passes through the mixing tube, the combustible gas mixes with the air entering from the air suction port, such that an additional oxygen cylinder is not needed. Therefore, the overall structure is light, convenient to convey.
