Patent number: 9973958Abstract: Systems and methods for improved inter-frequency measurement are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The eNB may determine a measurement pattern indicating when the UE should perform inter-frequency measurements. The measurement pattern may be selected such that the UE performs measurements more often than once per measurement cycle. The measurement pattern may be selected to balance timing requirements for the UE with increased power consumption that may result from more frequent measurements. The eNB may determine the measurement pattern based on an estimate of UE speed and a number of frequencies to be monitored. A default pattern may be used if the UE speed and/or number of frequencies do not exceed predetermined thresholds.Type: GrantFiled: September 26, 2014Date of Patent: May 15, 2018Assignee: INTEL IP CORPORATIONInventors: Rui Huang, Yang Tang, Yujian Zhang, Hong He, Candy Yiu

Patent number: 9935832Abstract: Mechanisms for designating particular nodes in a network as measurement endpoint (MEP) nodes are disclosed. Network topology information that identifies a plurality of nodes and communication links in a network is accessed. An initial chromosome generation is established. Each chromosome in the chromosome generation comprises a structure that identifies each node in the plurality of nodes that has an MEP capability and that includes an MEP state indicator for each node. A succession of a plurality of chromosome generations are generated by evolving each chromosome generation into a successive chromosome generation based on a genetic selection function and a fitness function until a threshold condition is met. An optimal chromosome from a successive chromosome generation is determined.
