Method and apparatus are disclosed for implementing a nonstandard bandwidth at a network device. According to an embodiment, a first amount of physical resource blocks (PRBs) available in the nonstandard bandwidth is determined. A second amount of PRBs available in a standard bandwidth corresponding to the nonstandard bandwidth is determined. A central frequency shift of the nonstandard bandwidth relative to the standard bandwidth is determined based at least on the first amount of PRBs and second amount of PRBs. A network device comprising the apparatus is also disclosed.
