Abstract: Embodiments of the present disclosure relate to machine learning for channel estimation against diverse Doppler effects. In this solution, the first device receives user data in a slot from a second device via a channel between the first device and the second device, the user data includes a reference symbol. Then, the first device performs, with a NN, a first channel estimation for the channel based on information on velocity of a second device and a result of a second channel estimation for the channel. The second channel estimation is performed based on the received reference symbol. After that, the first device transmits, to the second device, an indication of a result of the first channel estimation. With this solution, channel estimation is able to be performed in diverse scenarios (e.g., diverse Doppler scenarios, high-velocity scenarios and the like) with low overheads in reference signals (e.g., 1 DMRS), thereby reducing network consumption.

Abstract: Disclosed are methods for autonomous grouping. An example method, which may be performed at a first mobile station, may include: monitoring a change of a moving pose of the first mobile station; transmitting, to at least one mobile station comprising a second mobile station, information associated with the moving pose of the first mobile station in a case of a detection of the change; and configuring a group of the first mobile station based on a response of the second mobile station to the information. Related apparatuses and computer readable media are also disclosed.

Abstract: Examples of the disclosure relate to communication methods and apparatuses, an access point, stations and a computer readable medium. An embodiment of the method comprises: determining, at an access point and based on determining that a direct link between stations based sensing procedure is triggered, a first station and a second station associated with the sensing procedure; and transmitting, to at least one of the first station and the second station, a sensing performing request for performing the sensing procedure. In this way, target sensing between non-access-point stations is achieved, such that sensing coverage is extended and a sensing effect is improved.
