Title: Dynamic configuration of physical transport data frame of flexible orthogonal frequency division multiplex
Inventor: MICHAEL J SIMON
IPC: H04L27/26
Filed: 2019-09-03
Abstract: To construct physical transport frame of OFDM dynamically.SOLUTION: A frame includes multiple compartments, OFDM symbol of each compartment can have a corresponding cyclic prefix size and corresponding FFT size. For example, a different compartment, such as a user device having different maximum delay diffusion and/or a range of different mobility, may have a goal of different collection of user device. Furthermore, sample speed of each frame can be reconfigured dynamically, and further resolution is possible in control of subcarrier interval. Since the cyclic prefix of different OFDM symbol can have a different length, a frame conforming to the payload interval, having an arbitrary value of the cyclic prefix size in each compartment and the FFT size of each compartment can be constructed. The compartments can be multiplexed by time and/or frequency.SELECTED DRAWING: Figure 18
