20130058256 | PORT MAPPING METHOD AND APPARATUS, AND COMMUNICATION SYSTEM - Embodiments described herein disclose a port mapping method and apparatus, and a communication system. A method includes: obtaining static port mapping information that includes a corresponding relationship between a public network port number, a DHCP client identifier, and a private network port number; obtaining a corresponding relationship between the DHCP client identifier and a private network IP address, and a public network IP address of a NAT gateway; and establishing a port mapping relationship according to the obtained public network IP address of the NAT gateway, the corresponding relationship between the DHCP client identifier and the private network IP address, and the static port mapping information. | 03-07-2013 |
20130083768 | UPLINK BASEBAND SIGNAL COMPRESSION METHOD, DECOMPRESSION METHOD, DEVICE AND SYSTEM - Embodiments of the present invention disclose an RRU, which performs IDFT on a PUSCH signal that is obtained after resource block demapping, where due to a characteristic of an extremely low peak to average power ratio of SC-FDMA modulation, a signal after IDFT has an extremely low peak to average power ratio at this time, and an amplitude range of the signal changes slightly; amplitude/phase conversion is performed on the signal after the IDFT, where the signal after the IDFT is represented by using amplitude and phase, and then amplitude quantization and phase quantization are performed respectively to obtain a quantized amplitude signal and a quantized phase signal respectively. | 04-04-2013 |
20130117480 | METHOD FOR CONFIGURING STORAGE SYSTEM CONNECTION, DEVICE AND STORAGE SYSTEM - A method for configuring a connection in a storage system is provided. A configuring device determines that the configuring device cannot communicate with a first control board; searches a route information table for route information related to the first control board, wherein the route information is route information between an adapter card and the first control board, wherein the adapter card is connected to a north bridge of the first control board through a PCIe bus; modifies the searched out route information by changing an address of the first control board in the route information to an address of a second control board, and stores the modified route information in the route information table. | 05-09-2013 |

20130100151 | DISPLAY DRIVER PROCESSING METHOD, DEVICE AND SYSTEM - A computing machine includes a virtual machine monitor and a display adapter. The virtual machine monitor receives a graphics device interface (GDI) instruction including display content information and virtual machine identification information from a virtual machine, obtains video memory identification information by querying a correspondence between the virtual machine identification information and the video memory identification information, and sends a display driver message including the display content information and the video memory identification information to the display adapter. The display adapter receives the display driver message, stores the display content information in a video memory in the display adapter according to the video memory identification information, and sends the display driver message to a client terminal via a network interface card in the display adapter. | 04-25-2013 |
20130100909 | METHOD AND APPARATUS FOR RETRIEVING A TRANSMISSION OPPORTUNITY CONTROL IN REVERSE DIRECTION GRANT - Embodiments of the present invention disclose a method and an apparatus for retrieving transmission opportunity control in reverse direction grant, so that a conflict occurring between a case where an RD Initiator continues sending another frame to an RD Responder after retrieving TXOP control and a case where a terminal other than the RD Initiator sends a block acknowledgement to the RD Responder can be avoided. The method provided in the embodiments of the present invention includes: when an RD Initiator fails to correctly demodulate a frame sent by an RD Responder, retrieving, by the RD Initiator, TXOP control by using a PIFS if it is impossible for the RD Responder to enable an MU-MIMO mode, and retrieving, by the RD Initiator, the TXOP control by using a duration if it is possible for the RD Responder to enable the MU-MIMO mode, where the duration is longer than the PIFS. | 04-25-2013 |

20130144954 | Method and Apparatus for Cooperation Between Push Devices - A method and an apparatus for cooperation between push devices to improve the validity and reachability of Internet Protocol (IP) connections. The method for cooperation between push devices includes: obtaining, by a Push proxy, a Push identifier and an address of a Push client; storing, by the Push proxy, a mapping between the Push identifier and the address of the Push client; and if the address of the Push client changes, updating, by the Push proxy, the corresponding address in the mapping. With the embodiments of the present invention, validity and reachability of IP connections can be improved, and the real-time performance and reliability of Push messages can be improved. | 06-06-2013 |
20130148608 | MULTI-ANTENNA DIVERSITY SCHEDULING METHOD AND APPARATUS - The present invention provides a multi-antenna diversity scheduling method and apparatus. The method includes: transmitting pilot signals through x transmit antennas, where pilot signals on 1 to x−1 transmit antennas are a product of pilot symbols and a phase sequence, the phase sequence changes with at least one of time and frequency, the phase sequence changes more frequently than a user channel, and x is a positive integer greater than or equal to 2; receiving a transient channel quality information (CQI) value returned by a user according to the pilot signals; and according to the CQI value and a scheduling algorithm, scheduling the user to transmit data. | 06-13-2013 |
