Abstract: A user equipment (UE) and a method are presented. The UE comprises a receiver unit and a processing circuit, and is configured for receiving wireless signals. The processing circuit is arranged for performing pre-detection of the received signals providing an initial estimation of transmitted signals. The processing circuit is also arranged for splitting the transmitted signal into disjoint subgroups, each one covering a subgroup of all layers used for the transmitted signal such that the subgroups together cover all the layers. The processing circuit is also arranged for interference cancellation performed on the subgroups of transmitted signals based on the initial estimation of the transmitted signals. The processing circuit is also arranged for detection of the subgroups of transmitted signals by utilization of an MLD algorithm, wherein the subgroup of layers within each one of the subgroups of transmitted signals is detected simultaneously.

Abstract: A failure compensation method includes detecting a Digital Beam-forming (DBF) coefficient of each of multiple transceiver channels in real time. When a failure of any one of the transceiver channels is detected, a current group of DBF coefficients of the multiple transceiver channels at a current failure status and corresponding failure mode information are obtained. Optimization processing is performed on the current group of DBF coefficients through a preset optimization algorithm so as to calculate a first group of DBF coefficients which is more adaptive to the failure mode information than the current group of DBF coefficients. The DBF coefficients of the transceiver channels are updated according to the first group of DBF coefficients.

Abstract: A device-cloud collaboration method, platform, and apparatus, where the device-cloud collaboration method includes: obtaining current spatial information of each target terminal; tracking a spatial information change of each target terminal, to obtain a spatial information change status of each target terminal; and determining, based on spatial information-based arbitration conditions preset for different target mobile applications and the spatial information change status of the target terminal corresponding to the different target mobile applications, whether to trigger subsequent operations related to the different target mobile applications. The device-cloud platform blocks a change in which the user is not interested through arbitration of a spatial information change of the user, and provides an appropriate spatial information change to a mobile application, or triggers a subsequent operation of the mobile application.
