Abstract
Integrated sensing and communication(ISAC)has been confirmed as one of the six scenarios in 6G system by the international telecommunication union(ITU).Sensing signal design is a crucial issue in researches of ISAC.Traditional uniform sensing signal shows the property of large time-frequency resource occupation and low signal design flexibility.Fortunately,non-uniform sensing signal design can help to overcome the above-mentioned problems.This paper overviews and compares the principle of three categories of non-uniform signal design,and proposes the corresponding application and link adaptations methods for ISAC sensing signal design.Finally,tests,verifications and performance comparisons for the three categories of non-uniform signal design are performed using on the ISAC prototype,which is developed by vivo.The results demonstrate that,the non-uniform sensing signal can achieve good sensing performance while significantly reduces the time-frequency resources.关键词
