System providing faster and more efficient data communication
A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine.

This application provides a reference signal sequence transmission method. The method includes: generating a reference signal sequence based on a frame number of a radio frame; mapping at least a part of reference signals in the reference signal sequence to a resource position that corresponds to the radio frame and that is used to transmit the at least a part of reference signals; and sending the at least a part of reference signals or an orthogonal reference signal at the resource position, where the orthogonal reference signal is obtained by multiplying the at least a part of reference signals by a preset orthogonal code. |

Wireless communication method and apparatus
Provided in embodiments of the present application are a wireless communication method and apparatus, capable of transmitting multiple SRS types. The method comprises: a terminal apparatus receiving trigger signaling sent by a network apparatus for triggering an aperiodic sounding reference signal (SRS); the terminal apparatus determining, according to the trigger signaling, an SRS type of the aperiodic SRS; the terminal apparatus determining, according to the determined SRS type, a resource and/or transmission mode for sending the aperiodic SRS; and the terminal apparatus sending to the network apparatus, on the basis of the determined resource and/or determined transmission mode, the aperiodic SRS. |
