Abstract
Systems, methods, apparatuses, and computer program products for feeder link data transport are provided. For example, baseband in-phase and quadrature (IQ) data may be processed at the transmitter and receiver of the feeder link. The orthogonal frequency division multiplexing (OFDM) waveform used in a beam may be modified for transmission over the feeder link. For example, the waveform may have a wider subcarrier spacing (SCS) and may fill an enlarged bandwidth than otherwise with a feeder link.
Claims20
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- transmit, on a feeder link, a stream of symbols multiplexed in series,
- wherein the stream of multiplexed symbols is ordered and is formed from one or more parallel streams of symbols represented by time-domain samples corresponding to one or more beams,
- wherein a sample rate of the stream of multiplexed symbols is greater than a sum of sample rates of the one or more parallel streams of symbols,
- wherein a duration of symbols of the stream of multiplexed symbols is shorter than a duration of symbols of the one or more parallel streams of symbols;
- and
- transmit, between sets of symbols of the stream of multiplexed symbols, one or more reference signals.
