Title: A FLEXIBLE AND SCALABLE AIR INTERFACE FOR MOBILE COMMUNICATION
Abstract:
A flexible time-frequency grid is proposed. A baseline OFDM format consisting of CP and a following symbol interval is scaled in time to generate a set of extended OFDM frame formats. The set of extended OFDM frame formats is further extended by scaling in bandwidth. The OFDM frame formats and the extended OFDM frame format set are used dynamically in the wireless communication system in accordance to the changes of the communication environment. Furthermore, various methods are proposed to avoid and/or combat performance degradation of the resource elements (REs) interfered by non-orthogonal REs in the neighborhood due to different OFDM symbol configurations in the flexible time-frequency grid.
