Samsung patents 5G scheduling tweak to save phone battery
Samsung has patented a method for 5G devices to manage data transmission timing more efficiently. The system waits for a specific delay period before applying new scheduling rules, which prevents conflicting signals and reduces the power needed to process data.
In the filing’s own words
Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security, and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. In addition, the present disclosure provides a method and a device for reducing terminal power consumption in a wireless communication system. A method of a terminal in a communication system, according to one embodiment of the present disclosure, comprises the steps of receiving, from a base station, downlink control information (DCI) including a minimum offset indication field that indicates a first minimum offset, confirming an application delay for applying the first minimum offset, and transmitting/receiving data to/from the base station on the basis of the first minimum offset after the application delay from the time when the DCI had been received, wherein, during the application delay from the time when the DCI had been received, DCI including a minimum offset indication field that indicates a minimum offset different from the first minimum offset cannot be received from the base station.
What exactly they claim (claim 1)
1. A method of a terminal in a communication system, the method comprising: receiving, from a base station, first downlink control information (DCI) in slot n, wherein the first DCI indicates a first minimum offset value; identifying an application delay for applying the first minimum offset value; and applying the first minimum offset value in slot n+k, where k is the application delay, wherein, in a time interval corresponding to the application delay from slot n, second DCI indicating another minimum offset value having a value different from the first minimum offset value is not received, and wherein the application delay is identified based on a subcarrier spacing of a physical downlink control channel (PDCCH), a subcarrier spacing of a physical downlink shared channel (PDSCH), and a symbol position of the first DCI in slot n.
