Abstract: Provided are a method and device for configuring a pilot, wherein the method includes: configuring a user pilot according to subcarrier indexes of REs occupied by the user pilot, wherein the subcarrier indexes of the REs occupied by the user pilot are in subcarrier indexes of REs occupied by user data on PUSCH, and include the following pilot parameters: REstart and RBnumber, and further include REset and/or REinterval; and adjusting power of a pilot at a transmitting end and performing pilot resource mapping according to Powerfactor corresponding to the pilot parameters, where Powerfactor=(REset+REinterval)/REset. Through the disclosure, the problem that a pilot design scheme of the PUSCH in the related art is poor on flexibility is solved.

Abstract: The present disclosure provides a method for detecting a random access signal. The method includes: determining a temporary peak detection sequence according to a received time domain random access signal; determining an interference cancellation weight for a frequency domain cyclic shift sequence corresponding to a search window in the temporary peak detection sequence, and performing interference cancellation on the temporary peak detection sequence according to the interference cancellation weight, obtaining a final peak detection sequence; and performing peak detection on the final peak detection sequence. The present disclosure discloses an apparatus and system for detecting a random access signal at the same time. According to the method, the present disclosure can eliminate the deterioration of the leak detection performance and the false detection performance caused by the interference during the random access signal detection, improve the detection accuracy and save resources.
