A system and method for borrowing one or more time slots for data transmission is disclosed. The system comprises a monitor module, a request module and an allocation module. The monitor module detects a trigger event for borrowing a time slot from a potential lender. The request module generates a borrowing request responsive to the trigger event. The allocation module receives a response responding to the borrowing request from the potential lender. The allocation module determines whether the borrowing request is approved based at least in part on the response. Responsive to an approval of the borrowing request, the allocation module allocates one or more designated time slots included in a first active period and the borrowed time slot included in a second active period for data communication.
