Samsung patents 5G method to cut power use for VR data

Samsung has filed a patent for a way to manage data retransmissions in 5G networks, specifically for high-speed applications like virtual reality. The method helps devices save battery by pausing their listening mode when they know a data packet was sent successfully, even if the network usually expects a confirmation.

Why it mattersThis could make VR headsets and other 5G devices last longer between charges by reducing unnecessary network checks.

In the filing’s own words

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to the present disclosure, when a configured grant is set, a terminal and a base station can efficiently transmit and receive data even when data to be transmitted from a CG resource has a short transmission time requirement.

What exactly they claim (claim 1)

1. A method performed by a terminal in a wireless communication system, the method comprising: receiving a control message comprising configured grant (CG) configuration information from a base station; based on the CG configuration information, identifying that information indicating deactivation of retransmission monitoring is configured; receiving information on an uplink transmission through a physical downlink control channel (PDCCH), the information on the uplink transmission being associated with a configured scheduling-radio network temporary identifier (CS-RNTI) having a new data indicator (NDI) configured as 0; and driving a discontinuous reception (DRX)-hybrid automatic repeat request (HARQ)-round trip time (RTT) timer after a first uplink data transmission based on the information received through the PDCCH.
