System and method for adaptive transmission time interval (TTI) structure

A method of communicating data in a wireless channel, the method comprising:

• receiving, by a user equipment (UE), a first message from a base station, the first message indicating a first transmission time interval length configuration;
• and
• communicating, by the UE, a first data transmission through a first transmission time interval of a radio frame and a second data transmission through a second transmission time interval of the radio frame, wherein the first transmission time interval has a first transmission time interval length,
• wherein the radio frame has the second transmission time interval having a second transmission time interval length which is different from the first transmission time interval length, and a boundary of first transmission time interval aligns with the second transmission time interval in a certain timing point within the radio frame, and
• wherein the first transmission time interval corresponds to a first frequency band of a first time-frequency region, and the second transmission time interval corresponds to a second frequency band of a second time-frequency region, the first time-frequency region occupying a different bandwidth partition than the second time-frequency region.

A user equipment (UE) configured for wireless communications, the UE comprising:

• a non-transitory memory storage comprising instructions;
• and
• one or more processors in communication with the memory, wherein the one or more processors execute the instructions to:
• receive a first message from a base station, the first message indicating a first transmission time interval length configuration;
• and
• communicate a first data transmission through a first transmission time interval of a radio frame and a second data transmission through a second transmission time interval of the radio frame, wherein the first transmission time interval has a first transmission time interval length,
• wherein the radio frame has the second transmission time interval having a second transmission time interval length which is different from the first transmission time interval length, and a boundary of first transmission time interval aligns with the second transmission time interval in a certain timing point within the radio frame, and
• wherein the first transmission time interval corresponds to a first frequency band of a first time-frequency region, and the second transmission time interval corresponds to a second frequency band of a second time-frequency region, the first time-frequency region occupying a different bandwidth partition than the second time-frequency region.

A base station comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• communicate a first data through a first transmission time interval of a radio frame, wherein the first transmission time interval has a first transmission time interval length;
• and
• communicate a second data through a second transmission time interval of the radio frame, wherein the second transmission time interval has a second transmission time interval length which is different from the first transmission time interval length,
• wherein a boundary of first transmission time interval aligns with the second transmission time interval at in a certain timing point within the radio frame, and
• wherein the first transmission time interval corresponds to a first frequency band of a first time-frequency region, and the second transmission time interval corresponds to a second frequency band of a second time-frequency region, the first time-frequency region occupies a different bandwidth partition than the second time-frequency region.
