20090197613 | METHOD AND APPARATUS FOR DETERMINING THE LOCATION OF A NODE IN A WIRELESS SYSTEM - A method and apparatus for determining the location of a node within a wireless communication system is provided herein. In order to determine the location of a node, a series of GSM network measurement reports (NMRs) received at multiple base stations are analyzed by location-finding equipment. Multiple reports from the same mobile unit are analyzed for their received signal strength and multiple location estimates are then determined for the node. The location estimates are then averaged and weighted to determine an accurate location estimate for the node. | 08-06-2009 |
20100267397 | METHOD AND APPARATUS FOR DETERMINING A MOBILITY OF A MOBILE STATION IN A WIRELESS COMMUNICATION SYSTEM - An infrastructure-based mobililty determination module (MDM) receives multiple measurement reports from the MS and, for each received measurement report, stores values corresponding to values included in the report that are associated with measurements of parameters associated with received signals, wherein each stored value is stored in association with a wireless access node sourcing the corresponding signal. For each of one or more pairings of received measurement reports, the MDM then determines a signal parameter measurement change value corresponding to a change from the signal parameter measurement values associated with a first measurement report of the pairing to the signal parameter measurement values associated with a second measurement report of the pairing. Based on the one or more signal parameter measurement change values, the MDM determines an average signal parameter measurement change value and, based on the average signal parameter measurement change value, determines a mobility of the MS. | 10-21-2010 |
20150365157 | Antenna Selection in Coordinated Multipoint Communications - An apparatus and method for antenna selection in uplink coordinated multipoint communications, where a plural number of geographically separated antennas are present, forming a plural number of cells. This apparatus and method relates to selecting a PRACH configuration, sharing information regarding the selected PRACH preamble amongst cells; an user equipment, upon receiving instruction from its serving cell, transmits a PRACH preamble. All cells, including serving cell, detects the selected PRACH preamble in the received PRACH transmission transmitted by the user equipment, determining pathloss information regarding the quality of the detected selected PRACH preamble, and selecting a set of cooperative multipoint antennas from the plural number of antennas based on the determined channel quality information for this user equipment. This apparatus and method is also applicable for antenna selection in the case of a single cell with a plural number of geographically separated antennas. | 12-17-2015 |
