This method includes (i) obtaining, for each oriented link of each node, P values Vjj′i, where i=1 to P, respectively representative of the distribution percentages of its maximum transmission capacity between elements placed into P different operating states, and (ii) building with these obtained values Vjj′i an operating state table of the nodes of the group, which for each of the links is representative of its available, unavailable, and, if any, partially available transmission capacities. | 2014-01-23 |
20140022946 | METHOD AND APPARATUS FOR SETTING REVERSE LINK CQI REPORTING MODES IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus for setting Reverse Link CQI Reporting Modes in an access terminal is provided, comprising determining a value for CQIReportingMode received as a parameter in a transmitted message and setting the reverse link CQI reporting mode of the access terminal based on CQIReportingMode value. The CQIReportingMode value is indicative of a reporting mode selected from a plurality of reporting modes. | 2014-01-23 |
20140022947 | HIGH-THROUGHPUT CHANNEL OPERATION IN A MESH WIRELESS LOCAL AREA NETWORK - High throughput channel operation in a mesh wireless local area network (WLAN) is disclosed. A mesh network comprises a plurality of mesh points and a network management entity (NME). The NME is configured to retrieve capability and configuration data from the mesh points. The NME configures at least one mesh point with respect to IEEE 802.11n channelization and legacy protection mode based on the capability and configuration data. | 2014-01-23 |
