Patent drawing
Patent drawing from the official filing.

Samsung describes a way for mobile devices to confirm data receipt in future wireless networks that send and receive information simultaneously. The method helps the phone determine exactly when it should send a confirmation signal based on how the network splits its frequency bands.

Why it mattersThis improves the reliability of high-speed data connections by ensuring devices correctly acknowledge received data in complex full-duplex scenarios.

In the filing’s own words

The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present invention provides a method for generating a type-1 HARQ-ACK codebook in a wireless communication system. A method performed by a terminal of a communication system according to an embodiment of the present invention may comprise the steps of receiving configuration information related to subband non-overlapping full duplex (SBFD), identifying at least one occasion for receiving a physical downlink shared channel (PDSCH), and receiving the PDSCH in a valid occasion among the at least one occasion, wherein, in case that the configuration information corresponds to a first configuration, the valid occasion is defined as either an occasion including only a first type symbol or an occasion including only a second type symbol, and wherein, in case that the configuration information corresponds to a second configuration, the valid occasion is defined as an occasion including only a first type symbol and an occasion including only a second type symbol.

What exactly they claim (claim 1)

1. A method performed by a terminal of a communication system, the method comprising: receiving configuration information related to subband non-overlapping full duplex (SBFD); identifying at least one occasion for receiving a physical downlink shared channel (PDSCH); and receiving the PDSCH at a valid occasion among the at least one occasion, wherein, in case that the configuration information corresponds to a first configuration, the valid occasion is defined as either an occasion including only a first type symbol or an occasion including only a second type symbol, and wherein, in case that the configuration information corresponds to a second configuration, the valid occasion is defined as the occasion including only the first type symbol and the occasion including only the second type symbol.
