Publication number: 20230059005Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.Type: ApplicationFiled: August 26, 2022Publication date: February 23, 2023Inventors: Jing SUN, Tao LUO, Tamer KADOUS, Juan MONTOJO, Xiao Feng WANG, Sony AKKARAKARAN
