Abstract: A method and system for sending transmission acknowledgement information are disclosed, which relate to the wireless communication field; and solves the problem that full-duplex communication cannot be performed smoothly. The method includes: when a sender completes to send a radio frame to a receiver and needs the receiver to reply transmission acknowledgement information, if the receiver is sending a radio frame to the sender, the receiver replies the transmission acknowledgement information to the sender according to a determined mode for the transmission acknowledgement information. The above technical scheme applies to the WLAN, which achieves a timely data transmission acknowledgement mechanism.

Abstract: Provided is a method for interference alignment applied to a multi-cell and multi-user Multiple Input Multiple Output (MIMO) system. The method includes that: a BS divides multiple users in a cell into a plurality of user groups, and notifies the multiple users of grouping information; and when one of the plurality of user groups is interfered by a neighbor cell, users in the one of the plurality of user groups cooperate with each other to perform interference alignment. The disclosure also provides a pre-coding method and system based on interference alignment. The disclosure, by means of grouping and cooperation of the users and designing of a receiving matrix of each user, achieves the effect of interference alignment in a signal transmission space of the BS.

Abstract: In a wireless network, full duplex communication is established using a half-duplex mechanism. During a full duplex communication opportunity, a first quantum of data is transmitted from a first station to a second station and a second quantum of data is received by the first station from the second station. The full duplex transmission opportunity is implicitly or explicitly established and ended using a transmission mechanism understood by half duplex wireless stations.
