    摘要： A multi-user multiplexing method, a base station, and a user terminal are disclosed. The method includes: a base station weights, using a precoding matrix, multiple data streams that need to be transmitted to N user terminals to obtain to-be-transmitted data streams mapped onto K physical transmit antennas; weights, using the precoding matrix, a pilot signal that needs to be transmitted to the N user terminals to obtain to-be-transmitted pilot signals mapped onto the K physical transmit antennas; and sends the to-be-transmitted data streams and the to-be-transmitted pilot signals to the N user terminals by using the K physical transmit antennas. The to-be-transmitted data streams and the to-be-transmitted pilot signals are mapped onto different time-frequency resources. N is a positive integer greater than or equal to 2, K is a positive integer, and the precoding matrix is calculated according to characteristics of channels from the K physical transmit antennas to the N user terminals.

    摘要： Embodiments of the present invention disclose a video data transmission method and a related device. The method may include: when a base station receives information about a selection result and measurement configuration information, where the information about the selection result and the measurement configuration information are sent by a selection apparatus, determining, by the base station according to the selection result, that the present base station is a primary base station; acquiring, by the base station, channel quality information by using the measurement configuration information; and generating, by the base station, decision information according to the channel quality information and video service information that is acquired from a transmission conversion apparatus, and sending the decision information to the transmission conversion apparatus, so that the transmission conversion apparatus instructs, according to the decision information, a unicast service network element to perform unicast transmission for video data and/or instructs, according to the decision information, a multicast service network element to perform multicast transmission for video data. According to the present invention, hybrid unicast and multicast transmission may be performed for a DASH service, so that a radio resource such as network bandwidth can be better used, and a user can obtain higher video quality.

    摘要： The present invention provides a method for device-to-device communication, a terminal for device-to-device communication and a base station. The method for the device-to-device D2D communication includes: a terminal receives uplink scheduling signaling transmitted by a base station with in a n th subframe, wherein the uplink scheduling signaling is used for scheduling D2D transmission within a (n+m) th subframe, and n and m are positive integers; the terminal implements the D2D transmission with in the (n+m) th subframe according to the uplink scheduling signaling. The D2D method, D2D terminal and the base station of the embodiments of the present invention may adopt different transmission modes of D2D control signaling under a condition that different frame structures are determined.
