Patent number: 9769850Abstract: The present invention provides a method, a device and a system for transmitting data, which relate to the field of network technology. A station sends a request-to-send frame to an access point to obtain a channel, at the same time, the access point actively sends a middle-clear-to-send frame, so as to indicate which stations can send data, thereby reducing the time overhead in the data transmission process, improving the flexibility of the system, and avoiding system errors. Specifically, the method includes: an access point AP receives a request-to-send RTS frame sent by a station STA; sends a middle-clear-to-send MCTS frame to a scheduled STA; receives an F frame sent by the scheduled STA according to the MCTS frame; sends a final-clear-to-send FCTS frame to another scheduled STA; and receives data sent by the another scheduled STA according to the FCTS frame. The present invention is applied to data transmission.Type: GrantFiled: October 27, 2015Date of Patent: September 19, 2017Assignee: Huawei Technologies Co., Ltd.Inventors: Lvxi Yang, Peng Wang, Fang Wang, Xun Yang

Patent number: 9755979Abstract: Capacity enhancement of a direct communication link using a variable redundancy delivery network. An estimated information rate between a source node and a terminal node may be partitioned into a first information rate provided via the direct communication link and a second information rate to be provided via the variable redundancy delivery network. One or more parameters of the variable redundancy delivery network may be calculated to provide the second information rate based on a non-uniform probability density of messages requested by the terminal node. Capacity and reliability of storage media devices in the variable redundancy delivery network may be traded off to provide the second information rate.

Patent number: 9736752Abstract: Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.Type: GrantFiled: December 22, 2005Date of Patent: August 15, 2017Assignee: QUALCOMM IncorporatedInventors: Rajiv Laroia, Pablo Anigstein, Vladimir Parizhsky, Murari Srinivasan, George Tsirtsis
