DYNAMIC OFDMA TYPE SELECTION

원문 (중국어)

Solutions for dynamic orthogonal frequency division multiple access (OFDMA) type selection include: determining, by the wireless network, a propagation delay between a user equipment (UE) and a base station of the wireless network that is serving the UE over an air interface; based on at least the propagation delay exceeding a first threshold, instructing, by the wireless network, the UE to use a first OFDMA type (e.g., direct Fourier transform spread orthogonal frequency division multiplexing DFTS-OFDM)) for the air interface; based on at least the propagation delay falling below a second threshold, instructing, by the wireless network, the UE to use a second OFDMA type (e.g., cyclic prefix OFDM), wherein the second threshold is no greater than the first threshold, and wherein the second OFDMA type is different than the first OFDMA type for the air interface; and providing, by the wireless network, the data traffic session for the UE.
