20150124709 | GENERALIZED OUTER LOOP LINK ADAPTATION - Methods and apparatus are disclosed for a generalized outer loop link adaptation procedure. A normal outer-loop control procedure corrects an estimated SINR, which may be inaccurate if the estimate SINR is mapped from a channel quality estimate that does not reflect the true radio link condition. A normal outer control procedure functions properly only when a normal Modulation and Coding Scheme (MCS) is selected. A normal MCS is the highest Modulation and Coding Scheme (MCS) with which the target Block Error Rate (BLER) can be achieved given a certain number of HARQ (Hybrid Automatic Repeat Request) transmissions. The present application discloses a generalized outer loop link adaptation procedure that functions properly whether the selected MCS is normal, aggressive, or conservative. | 05-07-2015 |
20150043433 | ALLOCATING FEEDBACK RESOURCES FOR CARRIER AGGREGATION - Methods and apparatus are disclosed for allocating PUCCH resources for HARQ feedback so as to minimize the total number PUCCH resources that are allocated while avoiding resource collision.

The base station configures a resource group for each user terminal. Each resource group comprises a predetermined number of the allocated resource sets. The base station sorts the user terminals in the order of priority from highest to lowest and selects, in order of priority, a resource set for each user terminal from its configured resource group. To select resources for the user terminal, the base station calculates a weight for each resource set available to the user terminal, and allocate an available resource set with minimum weight to the user terminal. | 02-12-2015 |

The average amplitude is measured for each of several possible groups of channelization codes for each of one or more nearby UEs that might be the targets of interfering HS-PDSCH messages. Testing whether the amplitude is approximately the same across the codes in a possible combination of channelization codes yields a metric value that indicates whether that particular combination of codes is likely to be transmitted to a given UE. A second metric that detects the most likely modulation for possible groups of channelization codes is also calculated. The metrics are combined to determine which combination of channelization codes and modulation scheme is most likely being used for addressing the neighboring UE. | 10-24-2013 |

20100061385 | METHOD AND SYSTEM FOR PROVIDING A ROUTING ARCHITECTURE FOR OVERLAY NETWORKS - A link state overlay routing protocol that is capable of routing based on flat identifiers is proposed. The very fundamental problem that exists with 5 routing based on flat identifiers is that the identifier space can not be aggregated. All existing routing is based on hierarchy and aggregations of IP-addresses to network addresses, so called subnetting. The proposed routing protocol is capable of deciding the best path to a destination taking into account different possible parameters (e.g., round trip time). The scalability of the 10 protocol is solved by not taking decisions based upon a single end-node identifier; instead the routing decisions are taken based on a network identifier. | 03-11-2010 |
