Samsung patents method to switch 5G signal shapes on the fly

This filing describes a way for a phone to change the mathematical shape of its uplink signal based on instructions from the cell tower. The phone checks a specific control message to decide whether to use a standard signal format or a different one for sending data.

Why it mattersIt helps networks manage data traffic more efficiently by allowing the tower to dictate the best signal format for each transmission.

In the filing’s own words

The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. Provided is a method comprising the steps of: receiving, from a base station, information indicating through higher layer signalling that a waveform change indicator for a PUSCH is included in DCI; receiving the DCI for scheduling the PUSCH from the base station, the DCI including the waveform change indicator; and transmitting uplink data on the PUSCH to the base station on the basis of the DCI, wherein the PUSCH is transmitted on the basis of CP-OFDM when the DCI includes an FDRA field and the FDRA field corresponds to resource allocation type 0.

What exactly they claim (claim 1)

1. A method performed by a terminal in a communication system, the method comprising: receiving, from a base station, information indicating that a waveform switching indicator for a physical uplink shared channel (PUSCH) is included in downlink control information (DCI) through higher-layer signaling; receiving, from the base station, the DCI scheduling the PUSCH, the DCI including the waveform switching indicator; and transmitting, to the base station, uplink data on the PUSCH based on the DCI, wherein, in case that the DCI includes a frequency domain resource assignment (FDRA) field and the FDRA field corresponds to resource allocation type 0, the PUSCH is transmitted based on cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM).
