METHOD AND APPARATUS FOR DOWNLINK OFDMA HAVING DFT-PRECODING APPLIED THERETO - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18341200 Titled 'METHOD AND APPARATUS FOR DOWNLINK OFDMA HAVING DFT-PRECODING APPLIED THERETO'
Simplified Explanation
The abstract describes a communication system, specifically for 5G or 6G networks, that supports faster data transfer rates compared to 4G LTE. The system involves a method performed by a base station, which includes determining the number of chunks on which a specific type of data processing called DFT precoding is performed. The base station also determines a power backoff value for its power amplifier. It then transmits information about the number of DFT-precoding chunks to a terminal device. Additionally, the base station sends downlink control information (DCI) to the terminal, which includes a field for allocating resources based on the number of DFT-precoding chunks. Finally, the base station transmits data to the terminal according to the resource allocation field in the DCI.
Original Abstract Submitted
The disclosure relates to a 5G or 6G communication system for supporting a higher data transfer rate beyond a 4G communication system, such as LTE. A method by a base station in a communication system according to an embodiment may include: determining the number of DFT-precoding chunks on which DFT precoding is performed; determining a power backoff value of a power amplifier (PA) of the base station; transmitting information indicating the number of DFT-precoding chunks to a terminal; transmitting downlink control information (DCI) including a resource allocation field, configured based on the number of DFT-precoding chunks, to the terminal; and transmitting data to the terminal according to the resource allocation field included in the DCI.
