The multi-dimensional co construction fair competition environment implements a full-automatic anti cheating mechanism, continuously reviews violations manually, and reviews the codes of the team to be awarded line by line, so as to establish a fair competition environment in an all-round way and ensure the fairness and impartiality of the competition. Introduction to race track title race track 1: joint design of AI based channel estimation and channel state information feedback organizer: China Academy of information and communication and oppo Guangdong Mobile Communication Co., Ltd. race task: this race title considers using AI's information compression ability, nonlinear recovery ability and even integrated optimization ability to take the pilot signal (csi-rs) on a small amount of time-frequency resources received by the user as the input, Strive to complete the channel characteristic information recovery as accurately as possible at the base station, so that the base station can realize the construction of high-quality wireless communication links. Specifically, the characteristics of this competition are as follows: Based on the requirements of wireless communication system close to reality, this competition examines the utilization of pilot signals and the feedback performance of channel characteristic information of contestants' schemes in a complex and diverse channel environment; In this competition, we need to evaluate the performance of the scheme respectively under the given conditions of two different pilot densities (full pilot and under pilot), and investigate the gain effect of the contestant's scheme for different pilot conditions; In the traditional communication module division, the channel estimation and channel state information feedback based on the received pilot will be designed and optimized independently. However, with the empowerment of AI technology, there are actually many implementation ideas on how to obtain better final feedback effect, such as integrated cross module joint design or sub module design according to classical division. Players can freely choose the most appropriate implementation method in order to achieve the best performance. Track 2: AI based high-precision positioning organizers: China information and Communication Research Institute, Huawei Technology Co., Ltd. and vivo Mobile Communication Co., Ltd. race task: this race question contains three test cases. Using the reasoning ability of AI, the channel characteristic information of users and surrounding base stations is processed as algorithm input, and the user position coordinates are output. Through the optimization of AI algorithm, the user positioning accuracy is improved. Specifically, the characteristics of this competition are as follows: under a given channel data set, this competition examines the generalization ability of player models in different spatial consistency scenarios; In view of the difference in the number of available sites, the reasoning ability of the player model in the case of different available sites is investigated; In this competition, we need to consider the difficulty of obtaining label data in the actual environment, and use a large amount of unlabeled data to assist a small amount of labeled data to jointly improve the positioning accuracy of the model. The schedule setting competition adopts the mode of online competition, offline sharing and award. Players sign up, form teams and submit work evaluation on the official competition platform datamountain. After the online competition is over and the works are reviewed, the top ten award-winning teams or individuals in the ranking list need to participate in the offline achievement sharing meeting and attend the award ceremony.
