Abstract
A method, device and computer readable medium for determining an Synchronization Signal Block (SSB) position. The SSB position is determined by determining an actual transmission position of a target SSB according to various SSB positions being set in a radio frame; and sending indication information of the actual transmission position to a terminal device, wherein the various SSB positions being set in the radio frame are spaced from each other by at least one OFDM symbol, and at least one slot in the radio frame comprises two SSB positions.

A determination method for an SSB position, performed by a network device, the method comprising:
- determining an actual transmission position of a target SSB according to various SSB positions being set in a radio frame;
- and
- sending indication information of the actual transmission position to a terminal device;
- wherein the various SSB positions being set in the radio frame are spaced from each other by at least one OFDM symbol, and at least one slot in the radio frame comprises two SSB positions;
- wherein in a case where a sub-carrier space is 480 kHz, a range of an OFDM symbol index value in the radio frame for a first OFDM symbol occupied by an SSB position is {16, 21, 26, 31, 36, 41, 46, 51}+112n, wherein n takes a value of 0 or 1;
- or in a case where the sub-carrier space is 960 kHz, a range of the OFDM symbol index value in the radio frame for the first OFDM symbol occupied by an SSB position is {16, 21, 26, 31, 36, 41, 46, 51, 56, 61, 66, 71, 76, 81, 86, 91}+112n, wherein n takes a value of 0 or 1.
