  • Device Algorithm Capabilities Different devices have different capabilities for algorithmic processing of received CSI. Based on their algorithmic capabilities, devices are divided into three categories:
  • Strong algorithmic adaptive compensation, or strong algorithmic adaptive adjustment capability Some devices are capable of executing advanced sensing algorithms. For example, even when the device is moving or in an unstable environment, it can effectively process received CSI. Therefore, even if the channel changes, it can distinguish whether the change is caused by the sensing target or by device movement.
  • Some devices can only execute intermediate perception algorithms. For example, when the environment is unstable due to device movement, the perception algorithm may find it difficult to accurately distinguish whether the channel changes are caused by people or changes caused by device movement. Therefore, it can only process CSI feedback from stationary devices (in stable environments). For example, a mobile phone is performing perception measurement interaction in a stationary state. If the phone is moved by someone, the phone will experience more channel changes on the basis of the original channel during the period of moving from one location to another. In this case, the perception measurement interaction and concurrent CSI data performed under such changes may not be processed by the perception initiator, resulting in poor perception effect. However, if the movement ends and the device is in a stable state, the perception initiator can still process the received CSI.

Abstract

La présente demande concerne un procédé de communication, comprenant les étapes suivantes : un côté de démarrage de détection envoie, à un côté de réponse de détection, une trame de demande de mesure de détection demandant une mesure de détection ; et pendant la mesure de détection, si le côté de réponse de détection se déplace, des premières informations d'indication indiquant que le côté de réponse de détection s'est déplacé sont envoyées au côté de démarrage de détection. Par conséquent, le côté de démarrage de détection peut connaître un état de mouvement du côté de réponse de détection à temps pendant la mesure de détection. Le flux de mesure de détection est adapté à des scénarios de mouvement de dispositif.
