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.

Abstract: Examples of the present disclosure relate to a method, device and apparatus for communication, and a computer-readable medium. An example of the method includes: conducting, based on a channel response between a transmitter and a receiver, spectral shaping on a first sequence at the transmitter, so as to obtain an intermediate sequence, where the spectral shaping at least partially counters the channel response; remapping the intermediate sequence, so as to obtain a second sequence, where the second sequence has less signal levels than the intermediate sequence; and transmitting the second sequence to the receiver, so as to train an equalizer of the receiver. In this way, the method can accelerate training of the equalizer without sacrificing performance of the equalizer or introducing any additional hardware cost.

Abstract: Embodiments of the present disclosure relate to methods, devices and apparatuses for optical communication, and a computer readable medium. An embodiment of the method comprises determining, at an optical line terminal, a channel characteristic of a channel from an optical network unit to the optical line terminal; determining, based on the channel characteristic, a preamble property for a transmission from the optical network unit to the optical line terminal, the preamble property at least partially compensating for transmission distortion caused by the channel characteristic; transmitting preamble information to the optical network unit, the preamble information being for generating a preamble having the preamble property; and receiving the preamble having the preamble property from the optical network unit. In this way, a training speed of an equalizer of the optical line terminal can be improved, and preamble overhead can be reduced.
