Samsung patents 5G method to fix delayed signal confirmations

Samsung has filed a patent for a method that helps 5G devices manage when to send back confirmation signals. If the usual time slot for sending these confirmations is blocked or overlaps with other data, the device waits and sends them in a later, available slot instead.

Why it mattersThis improves the reliability of 5G connections by ensuring important confirmation signals are not lost when network traffic is heavy.

In the filing’s own words

The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services The disclosure provides a user equipment (UE) in a wireless communication system and a method performed by the UE, including: receiving downlink data and/or downlink control signaling from a base station; and transmitting uplink data and/or uplink control signaling to the base station based on the downlink data and/or downlink control signaling received from the base station.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) in a communication system, the method comprising: receiving, from a base station, semi-persistent scheduling (SPS) configuration information via radio resource control (RRC) signaling, the SPS configuration information including information associated with deferral of a transmission of hybrid automatic repeat request-acknowledgement (HARQ-ACK) information bits for SPS physical downlink shared channels (PDSCHs); identifying a first physical uplink control channel (PUCCH) resource for a transmission of first HARQ-ACK information bits for SPS PDSCHs in a first slot, wherein the first PUCCH resource is configured by a parameter SPS-PUCCH-AN-List, and wherein the first PUCCH resource is not cancelled by an overlapping PUCCH or physical uplink shared channel (PUSCH) transmission; in case that the first PUCCH resource overlaps with a symbol indicated as downlink, determining a second slot associated with a transmission of one or more HARQ-ACK information bits from the first HARQ-ACK information bits; determining third HARQ-ACK information bits by appending the one or more HARQ-ACK information bits to second HARQ-ACK information bits; and transmitting, to the base station, the third HARQ-ACK information bits on a PUCCH or a PUSCH in the second slot.
