The method includes transmitting to a terminal a Physical Downlink Shared CHannel (PDSCH) on a downlink secondary cell and a Physical Downlink Shared CHannel (PDSCH) indicating the PDSCH on a downlink primary cell; and receiving a reception acknowledgement response on the PDSCH, which is transmitted from the terminal to an uplink primary cell. The PDSCH is transmitted when the downlink secondary cell becomes available, and the transmission timing of the reception acknowledgement response is determined by one of the PDSCH transmission timing or the PDCCH transmission timing. | 2014-02-06 |

20140036891 | Resource Management for a Mobile Telephone Terminal - A resource management unit for a mobile telephone terminal, with the terminal comprising radio transmission/reception means for transmitting and receiving radio frequency signals corresponding to bursts of symbols during allocated time slots, and a device able to operate in a first mode and in a second mode, said device interfering less with the transmission/reception of radio frequency signals when it is in the first mode than when it is in the second mode. The resource management unit is able to cause the device to change from one of the first and second modes to the other of the first and second modes during the same time slot. | 2014-02-06 |
20140036892 | SYSTEM AND METHOD FOR UNIVERSAL WIRELESS DISTRIBUTION - Systems and methods are disclosed to provide a bridge for a wireless distribution system compatible with legacy equipment, including the use of a bridge device having two WLAN modules, with the first WLAN module associating with one or more stations and the second WLAN module configured to associating with a legacy access point. Frames received by the first WLAN module are forwarded to the second WLAN module for transmission and frames received by the second WLAN module are forwarded to the first WLAN module for transmission on the basis of address information in the frames. | 2014-02-06 |
20140036893 | System and Method for Enforcing Uplink Wireless Medium Usage in Wireless Networks - The present disclosure discloses a method and network device for enforcing uplink airtime fairness in wireless local area networks. The disclosed network device receives usage limits associated with transmissions from one or more client devices. The client devices transmit packets to the network device via one or more uplink wireless mediums. The disclosed network device further collects wireless medium usage times associated with the client devices, and calculates a size for transmission windows corresponding to the client devices based on the wireless medium usage times and the usage limits. The transmission windows can be TCP advertisement windows whose size determines a rate of transmissions permitted over the wireless medium. Then, the disclosed network device sets the transmission window to the calculated size. | 2014-02-06 |
20140036894 | WIRELESS LOCAL AREA NETWORK-BASED POSITION LOCATING SYSTEMS AND METHODS - The location of one or more mobile nodes in a wireless local area network (WLAN) is determined. Nodes in the WLAN include respective ping drivers to generate ping event values related to transmit count stamps and receive count stamps for wireless messages exchanged between the nodes. Each wireless message is associated with a transmit offset corresponding to an expected transmit time. A sorting module groups the ping event values and produces a difference between the respective receive count stamps and the transmit count stamps for each wireless message. Based on the sorted ping event values, the sorting module generates transmit offset values relating to the transmit offsets. A space-time calibration unit generates, from the sorted differences and the transmit offset values, a clock rate solution and a location solution for at least one of the nodes in the WLAN. | 2014-02-06 |
20140036895 | Wireless Communication Signaling For Aggregate Data Units - Systems and techniques relating to wireless communications are described. A described technique includes obtaining data for a transmission to a wireless communication device. The wireless communication device can be configured to process incoming transmissions based on an aggregate data unit format that specifies signaling for aggregating multiple medium access control (MAC) data units. The technique includes, in a physical (PHY) frame, an aggregate data unit that is based on the data and the aggregate data unit format, the aggregate data unit including a single MAC data unit. The technique includes, in the PHY frame, an indication to signal that the MAC data unit in the aggregate data unit is singular and to cause the wireless communication device to accept the aggregate data unit without a corresponding block acknowledgement agreement. | 2014-02-06 |
