Samsung patents method to cut data overhead in 5G/6G uplinks

Samsung has filed a patent application for a method that reduces the amount of extra control data needed when a phone sends information to a cell tower. The system uses a specific type of control signal to tell the phone how much space to use for sending data, aiming to make 5G and 6G connections more efficient.

Why it mattersThis is a technical improvement to how mobile networks manage data traffic, which could help make future 5G and 6G connections slightly more efficient, though it is not a consumer-facing feature.

In the filing’s own words

The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. Specifically, the present disclosure relates to a method for transmitting and receiving an uplink data channel through MC-DCI and a device capable of performing same in a wireless communication system. The present disclosure provides a device and method capable of effectively providing services in a mobile communication system.

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 for configuring uplink data transmission supporting up to 8 layers; receiving, from the base station, information for configuring dynamic waveform switching for a physical uplink shared channel (PUSCH); receiving, from the base station, downlink control information (DCI) for scheduling the uplink data transmission, the DCI comprising scheduling information for the PUSCH and a waveform switching indicator for the PUSCH; and based on the DCI, transmitting the PUSCH to the base station, wherein the scheduling information comprises frequency resource allocation information for the PUSCH, and wherein a value of the frequency resource allocation information indicates one number among multiples of one or more predetermined integers, and as many consecutive resource blocks as a number corresponding to the one number are scheduled.
