20110223929 | SCHEDULING TRANSMISSION OF DATA AT A BASE STATION BASED ON AN INTERFERENCE INDICATOR MESSAGE FROM ANOTHER BASE STATION - A system includes a first base station of a first vendor configuration and a second base station of a second vendor configuration. A link is between the first and second base stations. The first base station is configured to receive at least one interference indicator message from the second base station, and schedule transmission of data based on the at least one interference indicator message. Scheduling the transmission of data includes determining whether to transmit the data using a current resource or to delay transmission of the data. | 09-15-2011 |
20110286499 | Reduced Complexity Channel Estimation for Uplink Receiver - The present invention proposes an LTE eNodeB receiver channel estimation technique that is referred to as reduced complexity minimum mean squared error (MMSE) technique for channel estimation. From the invention's assumptions, estimations and modified calculations, the present invention generates precise channel estimates of RS using the reduced complexity MMSE matrix and previously computed LS channel estimates H | 11-24-2011 |
20120099503 | Methods and Systems for User Equipment Positioning Using Intercell Interference Coordination - Methods, devices and systems for determining positions of user equipments (UEs) based on uplink position signals are described. Cooperating base stations measure received positioning signals and report measurements to serving base stations. Cooperating base stations can also adapt resource allocation to mitigate interference on the uplink to positioning signals. Cooperation between base stations can be coordinated via inter-base station links, e.g., X2 interfaces in LTE systems. | 04-26-2012 |
