Samsung patents method for organizing wireless data acknowledgments

Samsung has been granted a patent for a method that helps mobile devices confirm they have received data correctly. The system uses specific timing rules to organize these confirmation signals, or acknowledgments, based on how the data was scheduled by the network.

Why it mattersThis is a technical improvement to how 5G networks handle data verification, which may help ensure more reliable connections but is unlikely to be visible to everyday users.

In the filing’s own words

The present disclosure discloses a method and device for signal transmission. According to an aspect of the present disclosure, a method for receiving one or more physical downlink shared channel (PDSCH), includes: receiving, by a user equipment (UE), a physical downlink control channel (PDCCH), wherein the received PDCCH includes downlink control information (DCI) for scheduling one or more PDSCHs; receiving, by the UE, one or more PDSCHs according to the received DCI; determining and transmitting, by the UE, a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for one or more PDSCHs according to the received PDSCH and PDCCH.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving a physical downlink control channel (PDCCH) including downlink control information (DCI) for scheduling one or more physical downlink shared channels (PDSCHs); receiving the one or more PDSCHs based on the DCI; and transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for the one or more PDSCHs, wherein the DCI includes time resource allocation information associated with a PDSCH time domain resource allocation (TDRA) table T, wherein a candidate PDSCH receiving position for placing each HARQ-ACK bit in the HARQ-ACK codebook is determined based on a set of time offsets and a set of rows associated with the PDSCH TDRA table T, and wherein for a row of the PDSCH TDRA table T including more than one start and length indicator value (SLIV) entries: the set of time offsets is determined based on (i) a timing value between a PDSCH associated with the more than one SLIV entries and the transmission of the HARQ-ACK codebook and (ii) a difference between a slot where a last PDSCH of PDSCHs corresponding to the more than one SLIV entries is located and a slot where each of the PDSCHs is located, and the set of rows associated with the PDSCH TDRA table T includes a union of rows corresponding to the more than one SLIV entries.
