Section 6.3 says:
The Len parameter has a size of 11 bits. Hence, the total MAC PDU size is 2048 bytes.
It should say:
The Len parameter has a size of 11 bits. Hence, the total MAC PDU size is 2047 bytes.
There are 11 bits for indicating the size of the MAC PDU, thus according to me this indicates a maximum size of (binary) 111 1111 1111, which equals (decimal) 2047 (2**11 - 1).
The maximum of 2047 is also cited in the book "Fundamentals of WiMAX" by Jeffrey G. Andrews, Arunabha Ghosh and Rias Muhamed on page 48: "The maximum frame length is 2,047 bytes, which is represented by 11 bits in the GMH."
