Physical resource block PRB grid indication method and device

An apparatus, comprising:

• a non-transitory memory having a storage medium, wherein the non-transitory memory stores a program;
• and
• a processor in communication with the non-transitory memory, wherein the processor is configured to execute the program to cause the apparatus to:
• obtain location information, wherein the location information indicates an offset between a second location of a physical resource block (PRB) in a system common PRB grid and a first location in a synchronization signal block, the system common PRB grid having a first subcarrier spacing, the first location being a beginning subcarrier of the synchronization signal block and the first location overlapping with the PRB, and the second location being a boundary location of the PRB in the system common PRB grid, wherein a value of the offset is M indicating an offset of M subcarriers between the first location and the second location, M is a value of a preset value set, and the preset value set is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23};
• and
• send the location information via a physical broadcast channel.

An apparatus, comprising:

• a non-transitory memory having a storage medium, wherein the non-transitory memory stores a program;
• and
• a processor in communication with the non-transitory memory, wherein the processor is configured to execute the program to cause the apparatus to:
• receive a physical broadcast channel;
• and
• obtain location information carried on the physical broadcast channel, wherein the location information indicates an offset between a second location of a physical resource block (PRB) in a system common PRB grid and a first location in a synchronization signal block, the system common PRB grid having a first subcarrier spacing, the first location being a beginning subcarrier of the synchronization signal block and the first location overlapping with the PRB, and the second location being a boundary location of the PRB in the system common PRB grid, wherein a value of the offset is M indicating an offset of M subcarriers between the first location and the second location, M is a value of a preset value set, and the preset value set is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23}.

A method, comprising:

• receiving a physical broadcast channel;
• and
• obtaining location information carried on the physical broadcast channel;
• wherein the location information indicates an offset between a second location of a physical resource block (PRB) in a system common PRB grid and a first location in a synchronization signal block, the synchronization signal block including the physical broadcast channel, a primary synchronization signal and a secondary synchronization signal, the system common PRB grid having a first subcarrier spacing, the first location being a beginning subcarrier of the synchronization signal block and the first location overlapping with the PRB, and the second location being a boundary location of the PRB in the system common PRB grid, wherein a value of the offset is M indicating an offset of M subcarriers between the first location and the second location, M is a value of a preset value set, and the preset value set is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23}.
