20140098661 | CARRIER SELECTION POLICY FOR JOINT SCHEDULING FOR CARRIER AGGREGATION IN AN LTE-ADVANCED SYSTEM - Various embodiments of a semi-joint scheduling algorithm for carrier aggregation in an LTE-Advanced system are provided. The proposed semi-joint scheduling algorithm combines the advantages of independent scheduling and joint scheduling while avoiding the respective shortcomings, and provides a technical foundation for a wide adoption of the carrier aggregation technology. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. | 04-10-2014 |
20140106764 | DYNAMIC CARRIER ASSIGNMENT OF CARRIER AGGREGATION IN AN LTE-ADVANCED SYSTEM - Various embodiments of a scheme of dynamic activation and release of carrier aggregation in an LTE-Advanced system are provided. When transmission need of an LTE-Advanced user is large and the user is within coverage of at least one secondary component carrier, carrier aggregation is activated while a certain amount of resource of each component carrier is preserved to support carrier aggregation. This avoids unnecessary activation and waste due to signaling cost. When the primary component carrier of an LTE-Advanced user has sufficient resource to satisfy transmission need of the user or when the user is not within coverage of at least one secondary component carrier, carrier aggregation is released. This minimizes complex measurement and cost of controlling signals due to multi-carrier scheduling. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. | 04-17-2014 |
20140204777 | CELL SWITCHING STRATEGY FOR AN LTE-ADVANCED SYSTEM BASED ON CARRIER AGGREGATION TECHNOLOGY - Various embodiments of a cell switching strategy for an LTE-Advanced system based on the carrier aggregation technology are provided. Compared with the conventional cell switching strategy, the proposed strategy monitors the channel conditions of all the component carriers that are utilized for the communication of a user. The proposed strategy switches cell for one or more of the component carriers with relatively weaker signal strength while maintaining the cell for the other component carriers with better channel quality. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. | 07-24-2014 |
20150029952 | SELF-ADAPTIVELY IMPROVING SYSTEM STABILITY - In a wireless communication system, a base station may adopt AMC and HARQ mechanisms to improve the system stability and may further be configured to combine the feedback features of AMC and HARQ to save computing resources. | 01-29-2015 |
20150072718 | CONTROLLING PEAK-TO-AVERAGE POWER RATIO (PABR) - In an example embodiment, a transmitter of a wireless communication device may incrementally increase a level of transmit power by a predefined amount, based on a channel quality indicator, up to a limited maximum level of transmit power to control the peak transmit power and further may control the Peak-to-Average Power Ratio (PAPR). | 03-12-2015 |
