Patent number: 9042941Abstract: A method includes selecting a subset k of N accessible antennas to use to process a transmission received at the N antennas and sent by a user equipment, and processing the transmission from the user equipment at least by using baseband information from the k antennas. An apparatus includes one or more processors and one or more memories including computer program code. The one or more memories and the computer program code are configured to, with the one or more processors, cause the apparatus to perform at least the following: selecting a subset k of N accessible antennas to use to process a transmission received at the N antennas and sent by a user equipment; and processing the transmission from the user equipment at least by using baseband information from the k antennas. Additional apparatus, computer programs, and computer program products are disclosed.Type: GrantFiled: June 15, 2012Date of Patent: May 26, 2015Assignee: Nokia Solutions and Networks OyInventors: Phil Fleming, Shirish Nagaraj, Alan Rottinghaus, Roy Yang, Yuda Luz, David Baietto, Gerald Gutowski

Patent number: 8934561Abstract: A method is disclosed that includes accessing baseband information for a number, N (N>1), of antennas accessible by a number of baseband units, where the baseband information correspond to a transmission by a user equipment and is received at the N antennas. The method includes determining values for one or more metrics for the baseband information for the N antennas. The method includes selecting, based on the determined values, a subset k of the N antennas and corresponding baseband information to use to determine output data for the transmission by the user equipment. The method includes determining the output data for the user equipment using the baseband information from the k antennas. Apparatus and computer program products are also disclosed.Type: GrantFiled: June 15, 2012Date of Patent: January 13, 2015Assignee: Nokia Siemens Networks OYInventors: Phil Fleming, Shirish Nagaraj, Alan Rottinghaus, Roy Yang, Yuda Luz, David Baietto

Patent number: 8903369Abstract: Systems and techniques for managing interference between pico cells in a pico cluster. Pico eNodeBs are configured in groups for each of a plurality of UEs, based on factors such as signal to noise ratio and geographic location. All signals from UEs may be measured by all eNodeBs in the cluster, but a pico group decodes packets only of UEs associated with the pico group. Decoded packets are exchanged between pico groups, and when a pico group is unable to decode packets of an associated UE, is uses the decoded packets received in exchanges to reconstruct an interference signal. The interference signal is subtracted from the received signal and the resulting received signal is used to decode the packets of the UE.Type: GrantFiled: February 24, 2012Date of Patent: December 2, 2014Assignee: Nokia Siemens Networks OyInventors: Phil Fleming, Shirish Nagaraj, Raghavendra M. Ramakrishna, Michael Honig

Method for optimizing forward link data transmission rates in spread-spectrum communications systems
Patent number: 6947436Abstract: An apparatus and method that optimizes the data rate for forward link data transmissions in a spread-spectrum communications system 106 is provided. The spread-spectrum communications system 106 comprises a wireless infrastructure 103, at least one wireless mobile receiving device 105, and an radio frequency (RF) forward link 104 between the wireless infrastructure 103 and the wireless mobile receiving device 105. The data rate of the RF forward link 104 is optimized in the wireless infrastructure 103 by estimating or measuring the bottleneck link speed of the data transmission and adjusting the data rate for the RE forward link 104 according to several embodiments of a data rate optimization algorithm. The algorithm creates an optimum range for the data rate of the RF wireless link 104 which maximizes system capacity and reduces transmission delays to the wireless mobile receiving device 105.Type: GrantFiled: February 1, 2001Date of Patent: September 20, 2005Assignee: Motorola, Inc.Inventors: John M.
