Apparatus and method for subframe arrangement

An apparatus, comprising:

• at least one processor;
• and
• at least one memory including computer program code,
• wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
• generate at least one symbol of a subframe for control information based on a first subcarrier spacing;
• generate at least one data symbol of the subframe based on a second subcarrier spacing;
• and transmit the subframe comprising the at least one symbol for control information and at least one data symbol.

An apparatus, comprising:

• at least one processor;
• and
• at least one memory including computer program code,
• wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
• receive a subframe comprising at least one symbol for control information and at least one data symbol;
• decode the at least one symbol for control information based on a first subcarrier spacing;
• and obtain from the decoded at least one symbol information regarding a second subcarrier spacing used on the at least one data symbol.

A method, comprising:

• generating at least one symbol of a subframe for control information based on a first subcarrier spacing;
• generating at least one data symbol of the subframe based on a second subcarrier spacing;
• and
• transmitting the subframe comprising the at least one symbol for control information and at least one data symbol.
