  • the SBP perception measurement process includes SBP establishment interaction, perception measurement session establishment, perception measurement interaction, SBP reporting, and SBP shutdown.
  • the SBP initiator can perform perception measurement interactions with one or more devices within a negotiated perception time window. Based on different measurement types, the device can then be requested to provide a perception measurement report.
  • the current SBP perception measurement process is used in actual SBP perception measurement scenarios. However, due to factors such as dynamic changes in the perception scenario and increased interference, measurement results may be inaccurate.
  • a communication method is provided. This method can be executed by an SBP responder or by a chip or circuit in the SBP responder, and this application does not limit this.
  • SBP responder for ease of description, the following description uses the SBP responder as an example.
  • the SBP responder receives first indication information from the perception responder, including: after the first perception measurement interaction, the SBP responder receives a perception measurement termination frame from the perception response end, the perception measurement termination frame including the first indication information, wherein the first perception measurement interaction is the perception measurement interaction included in the perception measurement process.
  • the perception responding end may send a first perception measurement report frame, where the first perception measurement report frame may include a first perception measurement report measured during the first perception measurement interaction.
  • the first perception measurement report frame may not include a perception measurement report.
  • the sensing responder may transmit the first indication information by including the first indication information in a first sensing measurement report frame fed back during the first sensing measurement interaction. For example, the sensing responder moves during the first sensing measurement interaction, so that the sensing responder can feed back the first indication information via the first sensing measurement report frame. Reusing the existing sensing measurement report frame to feed back the first indication information can improve backward compatibility of the solution.

After receiving the second indication information, the SBP initiator knows that the sensing responder has moved, and the sensing measurement reports received before and after the movement may no longer be valid. Therefore, when executing the sensing algorithm, the SBP initiator can discard some data, avoiding further processing of erroneous data and reducing unnecessary system processing burden.

Abstract

La présente demande concerne un procédé de communication. Le procédé comprend les étapes suivantes : un répondeur SBP envoie à un répondeur de détection une trame de demande de mesure de détection pour demander la mise en œuvre d'une mesure de détection ; et, pendant la mesure de détection, si le répondeur de détection se déplace, envoyer à un initiateur de détection des premières informations d'indication servant à indiquer que le répondeur de détection s'est déplacé. Ainsi, un répondeur SBP peut en apprendre davantage concernant un état de déplacement d'un répondeur de détection en temps voulu pendant une mesure de détection. Le processus de mesure de détection est adapté à un scénario dans lequel un dispositif se déplace.
