Proactive Base Station Selection Based on Human Blockage Prediction Using RGB-D Cameras for mmWave Communications

Wireless-link-quality Prediction and Device-position Estimation Based on Relationship between Wireless-communication-link and Physical-space Information

“…Wireless-link quality is strongly affected by the objects blocking the line of sight between a base station and user terminals as the radio frequency becomes high such as over the SHF band (> 3 GHz). Wireless-link-quality prediction for the millimeter wave (60 GHz) was proposed [9], and the authors used a depth camera to detect signal blocking. We developed prediction technologies for the SHF band by using high-definition (HD) cameras and confirmed that the long-term prediction corresponding to second-order future was achieved using physicalspace information [10].…”

“…With the progressive development of intelligent business, such as intelligent transportation and autonomous driving, abundant types of sensors, including Radar, LIDAR and Depth/RGB cameras, will be mounted on the communications equipment or the infrastructures [3]- [4]. These sensors can be explored to assist many communications tasks, such as beam alignment [5]- [8], channel covariance matrix estimation [9], as well as the prediction for blockage, base station (BS) handover, as well as received power [10]- [11]. Among them, the visual perception by cameras has drawn much attention recently, due to its universality, low cost, and high resolution compared with the Radar and LIDAR.…”

“…Naturally, user matching, i.e., identifying the visual user from all the environmental objects, is a critical problem for the visual aided communications. However, the authors of [10]- [11] assume the user is static. The authors of [12] design a vision aided service identification method, and the authors of [13] propose a vision based beam selection method.…”
