Patent ID: 11916712

Abstract:
Method and apparatus to use different GI sequences for different FDM UEs. The apparatus calculates a GI of each UE from a set of UEs based at least on a delay spread associated with each UE from the set of UEs. The apparatus multiplexes data and the GI of each respective UE from the set of UEs to generate a waveform. The apparatus transmits the waveform to the set of UEs. The apparatus may receive, from each UE from the set of UEs, the delay spread associated with each UE from the set of UEs. The apparatus may multiplex the GI of each respective UE from the set of UEs prior to performing a DFT operation on the GI and the data. The apparatus may multiplex the GI of each respective UE from the set of UEs after performing an IDFT operation to generate the waveform.
