Subcarrier mapping techniques for guard interval-based orthogonal frequency division multiplexing communications
摘要
說明書
In some cases, the control information 215 may indicate that OFDM symbols within the GI-based OFDM communications 220 include a first set of time-domain guard interval samples and a second set of time-domain data samples, and a permutation matrix is to be used to map a first set of guard interval inputs to a subset of a set of subcarriers for the OFDM communication. The UE 115-a and the base station 105-a may communicate via the communication link 210 in accordance with the configured GI-based communications 220. In some examples, the UE 115-a and the base station 105-a may communicate over a relatively high operating frequency band, such as frequency range two (FR2), using GI-based OFDM waveforms that support uplink communications, downlink communications, or both. In some cases, UE 115-a and base station 105-a may use multiple different types of waveforms, which may include GI-based OFDM waveforms, cyclic prefix (CP)-OFDM waveforms, single carrier frequency domain waveforms (e.g., DFT-s-OFDM), a single carrier time domain waveforms (e.g., single carrier quadrature amplitude modulation (SC-QAM)), or any combinations thereof.
