Abstract: In the method, a first device receives a mixed signal including a target signal from a target device among a plurality of second devices and an interfering signal from the plurality of second devices. The first device determines a distribution characteristic of an amplitude of the mixed signal within an amplitude variation range, the distribution characteristic being associated with the target device and an interfering device generating the interfering signal. The first device determines the interfering device from the plurality of second devices based on the distribution characteristic. An interfering device in a communication system may be detected in real-time and accurately.

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: Example embodiments of the present disclosure relate to channel state based beamforming enhancement. A first device receives, from a second device, a second message indicating a second channel state. The second message has a second length less than a first length of a first message indicating a first channel state previously received from the second device. The first device obtains combined beamforming features of the second device according to a trained combining model associated with the second device and based on the second message and historical beamforming features of the second device. The first device generates a beam weight for the second device according to a trained beamforming model and based on the combined beamforming features. The first device may generate a beam weight for the second device according to the beamforming model without recovering CSI from the message.

Abstract: Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer-readable medium for signal equalization. According to the embodiments of the present disclosure, a balance between equalization performance and effects is achieved by using a linear equalizer and a nonlinear equalizer. In addition, signals from different uplinks are equalized using adaptive parameters, to achieve optimal equalization of various signals.
