7. The method according to claim 1 , wherein determining the target k ssb based on the target association relationship and the offset comprises:
determining, in response to communicating with a terminal in a target frequency range, the target k ssb based on the target association relationship and the offset.

9. A method of determining an offset, performed by a terminal, comprising:
determining a target association relationship between a value of offset indication information k ssb and a number of corresponding offset resource elements (REs), wherein the target association relationship comprises: in response to determining that a subcarrier spacing of remaining minimum system information (RMSI) is greater than a subcarrier spacing of a synchronization signal block (SSB), a ratio of the number of corresponding offset REs to the value of the offset indication information k ssb is equal to a quotient of the subcarrier spacing of the RMSI divided by the subcarrier spacing of the SSB; and
determining an offset of the RMSI with respect to the SSB based on a target k ssb that is received and the target association relationship.
