Apparatus and method for inter-band pairing of carriers for time division duplex transmit- and receive-switching and its application to multiplexing of different transmission time intervals

A scheduling entity configured for wireless communication, comprising:

• at least one processor;
• a non-transitory computer-readable medium communicatively coupled to the at least one processor;
• and
• a transceiver communicatively coupled to the at least one processor,
• wherein the at least one processor is configured to:
• utilize the transceiver to transmit a scheduling grant to at least one subordinate entity to grant resources on a first carrier for wireless communication between the scheduling entity and the at least one subordinate entity, the first carrier being a time division duplex (TDD) carrier;
• utilize the transceiver to wirelessly communicate with the at least one subordinate entity utilizing a first transmission time interval (TTI), utilizing the granted resources on the first carrier
• utilize the transceiver to wirelessly communicate with the at least one subordinate entity utilizing a second TTI having a different duration than the first TTI and at least partially overlapping the first TTI, over a second carrier paired with the first carrier but separated from the first carrier in frequency;
• and
• utilize the transceiver to transmit a grant modification to the at least one subordinate entity to modify the granted resources of the scheduling grant transmitted to the at least one subordinate entity.
