A common protocol structure is to have a header containing a length field, followed by data of length bytes, followed by additional protocol fields such as a CRC. If the length field is variable, the position of subsequent URH-specified protocol fields defined by fixed position will not be in the correct location.

I do not know the best way to address this, but quick and easy way to support

The concept of the WRAN software uses the IEEE 802.22 frame structure for prototyping to make use of super frames and preambles for cognitive channel management, which allows a dynamic resource allocation between base stations, but also between multiple users at one base station. Orthogonal Frequency Division Multiple Access (OFDMA) is used in the upper layers, as Modulation techniques QPSK, 16-QAM and 64-QAM is supported. The software will support a connection-oriented MAC layer with cognitive functionality for dynamic and adaptive scheduling and management of coexistence of base stations in the same time-frequency domain (super frames).
