Abstract: Embodiments of the present application provide a method and an apparatus for CSI feedback, an electronic device, and a storage medium. The method for CSI feedback includes: determining a CSI measurement resource corresponding to each data layer group during CSI measurement; determining first correspondence relations between each data layer group and DMRS ports during CSI measurement; determining mapping modes between each data layer group and CSI-RS ports during CSI measurement; determining transmission mode used in CSI measurement and CSI reporting mode corresponding to the transmission mode; and performing CSI feedback according to the CSI measurement resource, the first correspondence relations, the mapping modes, the transmission mode used in the CSI measurement and the CSI reporting mode corresponding to the transmission mode. Therefore, the embodiments of the present application improve flexibility and accuracy of CSI feedback and reduce complexity of CSI feedback.

Abstract: A wireless transmission scheduling method is proposed. The method may be a synchronous media access control (MAC) wireless transmission scheduling method optimized for a user datagram protocol (UDP) of a personal wireless network-based data transmission system. The method may include setting a superframe period, a beacon period, and a contention period by a master station in a network. The method may also include calculating transmission periods of one or more slave stations participating in the network and a transmission period of the master station. The method may further include transmitting information about the calculated transmission periods of the one or more slave stations to the one or more slave stations participating in the network. The method may further include transmitting data by the one or more slave stations and the master station in the transmission periods assigned to the one or more slave stations and the master station.
