Abstract
System and method embodiments are disclosed to provide mechanisms wireless communications. A method comprises transmitting, by a network device to a non-long term evolution (LTE) user equipment (UE), a bandwidth partitioning information describing a non-LTE bandwidth partition of a system bandwidth. The system bandwidth comprises an LTE bandwidth partition coexisting with the non-LTE bandwidth partition in the system bandwidth, and the LTE bandwidth partition is within the non-LTE bandwidth partition or the LTE bandwidth partition is adjacent to the non-LTE bandwidth partition.
