Slater Matsil, LLP
Signal processing method and apparatus
A method includes: generating a reference signal sequence based on a first m-sequence and a second m-sequence, where the reference signal sequence is a gold sequence, a cyclic shift value of the first m-sequence is determined based on a physical cell identifier and first timing information, and for a same physical cell identifier, a difference between two cyclic shift values of the first m-sequence that are separately determined based on the physical cell identifier and any two pieces of adjacent first timing information is L1, where L1 is a positive integer, and the first timing information includes a synchronization signal block time index or a first part of the synchronization signal block time index; and after modulating the generated reference signal sequence, mapping a modulated reference signal sequence to N subcarriers to obtain a reference signal, where N is a positive integer greater than or equal to 1.
