DEMODULATION REFERENCE SIGNAL BASED MODULATION AND CODING SCHEME DETERMINATION IN DOWNLINK ALLOCATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18185836 titled 'DEMODULATION REFERENCE SIGNAL BASED MODULATION AND CODING SCHEME DETERMINATION IN DOWNLINK ALLOCATION
The abstract describes a method for determining the modulation and coding scheme (MCS) in downlink allocation based on the demodulation reference signal (DMRS) in a wireless communication system.
- Transmitting a first transmission with a first MCS and DMRS to a second device via a downlink channel.
- Receiving a second transmission from the second device containing channel quality data and HARQ data in response to the first transmission.
- Adjusting the MCS based on the channel quality data to apply a second MCS to a third transmission.
Potential Applications: - Wireless communication systems - 5G networks - Internet of Things (IoT) devices
Problems Solved: - Efficient allocation of resources in downlink communication - Improving data transmission reliability - Enhancing overall network performance

Original Abstract Submitted
Demodulation reference signal (DMRS) based modulation and coding scheme (MCS) determination in downlink allocation is described herein. A method as described herein can include transmitting, by a first device comprising a processor, a first transmission to a second device via a downlink channel, wherein the first transmission utilizes a first MCS and comprises a DMRS; receiving, by the first device, a second transmission from the second device in response to the transmitting of the first transmission, wherein the second transmission comprises channel quality data, indicative of a channel quality of the downlink channel as estimated by the second device based on the DMRS, and a hybrid automatic repeat request (HARQ) data corresponding to the first transmission; and adjusting, by the first device, the first MCS based on the channel quality data, resulting in a second MCS to be applied to a third transmission to the second device.
