Title: Reference signal sending and signal detection method and apparatus
Inventor: WEI YI
IPC: H04L27/26
Filed: 2019-09-10
Abstract: A reference signal sending and signal detection method and apparatus. The method comprises: determining an initial seed parameter of a pseudo-random sequence, and generating a pseudo-random sequence according to the initial seed parameter, wherein the initial seed parameter is determined according to attribute information of the terminal device; determining a cyclic shift value according to the pseudo-random sequence, and determining a reference signal according to the cyclic shift value; and sending the reference signal to the network device. In the method flow, the initial seed parameter of the pseudo-random sequence for determining a cyclic shift value is determined according to the attribute information of the terminal device. Therefore, different terminal devices use different pseudo-random sequences for determining a cyclic shift value. According to the method, the difference between the cyclic shift values used by any two terminal devices in a cell to determine a reference signal can be randomized, so that the interference between reference signals sent between terminal devices can be reduced, thereby realizing the effect of interference randomization, and improving the performance of channel time domain filtering.
