Abstract: A multimedia redirection method, a multimedia server, and a computer system. The method includes: receiving a virtual-desktop login request of a user, where the virtual-desktop login request includes an identifier of the user; acquiring, according to the identifier of the user, metadata of a multimedia instance that is not shut down by the user before a last disconnection, where the metadata includes path information of a multimedia file corresponding to the multimedia instance; and sending the metadata to a client of the user so that the client acquires, according to the metadata, multimedia data corresponding to the metadata and plays the multimedia data. The adoption of technical solutions of the present invention can implement that multimedia that is not closed before a last disconnection may be automatically played when a user logs in again, thereby improving experience of multimedia application of the user.

Abstract: This application discloses a wireless communication apparatus and a signal processing method. The wireless communication apparatus includes a power amplifier and a bias circuit. The power amplifier includes a signal input port, a signal output port, a power supply port, and a bias port. The power amplifier is configured to: receive a power supply signal through the power supply port, receive a bias signal through the bias port, receive a radio frequency signal through the signal input port, and output a power amplified radio frequency signal. The bias circuit is configured to generate the bias signal. A timing feature of the bias signal is synchronized with a timing feature of a switch signal of a power amplifier, to compensate for a nonlinear change in the TDD scenario.

Abstract: A resource scheduling method and apparatus. The method includes: determining at least one candidate destination physical machine and a physical machine on which a to-be-scheduled virtual machine is located; calculating a candidate communication cost required after the to-be-scheduled virtual machine is scheduled in a simulative way to each candidate destination physical machine; determining a destination physical machine among the at least one candidate destination physical machine according to the communication cost; and scheduling the to-be-scheduled virtual machine to the destination physical machine. In the solutions provided in the embodiments of the present invention, a destination physical machine is determined by calculating a candidate communication cost required after the to-be-scheduled virtual machine is scheduled in a simulative way to each candidate destination physical machine, and then resource scheduling is performed.
