Abstract
As a promising technique for 6G integrated sensing and communication,cooperative integrated sensing and communication (CoISAC) technology harnesses additional sensing information from various network nodes to over-come challenges of ISAC systems such as low sensing accuracy,non-line-of-sight path scenario,and limited sensing range. The current status of CoISAC technology was summarized and analyzed. A novel performance metric and two cooperative approaches were proposed. The challenges faced by CoISAC technology were analyzed,and the future development trend of CoISAC technology was forecasted.
