20150146679 | INTERFERENCE CANCELLATION IN WIRELESS NETWORKS - The present application relates to a method of a wireless device for interference cancellation (IC) in a cellular radio network system comprising a serving network node serving said wireless device. The method comprises using a first IC method for at least partly removing a time aligned symbol of an interfering radio signal from at least a first symbol of a time slot received from the serving network node. The method also comprises using a second IC method, different from the first IC method, for at least partly removing a non-time aligned symbol of an interfering radio signal from at least a second symbol of said time slot received from the serving network node. | 05-28-2015 |
20150105031 | Efficient Whole-Body SAR Estimation - A method for estimating a whole-body Specific Absorption Rate (SAR) caused in a body by electromagnetic fields emitted by a wireless communication device ( | 04-16-2015 |
20140192727 | METHODS AND ARRANGEMENTS IN A WIRELESS COMMUNICATION SYSTEM - Method and arrangement in a user equipment for adjusting signals transmitted in uplink to a network node based on a feedback value received from the network node. The method includes transmitting a signal, to be received by the network node. A feedback signal is received from the network node, providing feedback on the transmitted signal. A value of a time delay of the received feedback signal is obtained. Signals transmitted in the uplink are adjusted according to the received feedback signal to compensate for the obtained time delay value of the received feedback signal. Related methods and arrangements in a network node are presented. | 07-10-2014 |
20130219048 | Quantifying User Quality of Experience by Passive Monitoring - A method is implemented in a network element to generate quality of experience (QoE) metrics for hypertext transfer protocol (HTTP) sessions over a network between a user device and an HTTP server. The QoE metrics are based on detecting premature termination of a download process that indicate low QoE. This QoE metric data can then be utilized by network administrators or service providers to adjust network characteristics to improve the QoE or to offer changes in services to a customer that would improve the QoE. | 08-22-2013 |

20120281142 | TECHNIQUE FOR VIDEO QUALITY ESTIMATION - An objective video quality estimation technique is disclosed. The technique may be based on a video bitstream model, using parameters taken from the video coding layer of the bitstream for estimating the quality of the video. The technique can be implemented as a method, a computer program, a computer program product, a device, or any one of a server node, a client terminal and a network node comprising the device. As a method embodiment, the technique comprises receiving a video bitstream comprising a series of picture frames; determining an error occurrence in a picture frame of the video bitstream; determining at least one of a temporal propagation and a spatial propagation of the error; and estimating the quality of the video bitstream based on result of the determination. | 11-08-2012 |
20110310868 | P-GW/GGSN ISSUED PAGING REQUESTS - Example embodiments presented herein provide a system and method enabling optimized communication in a wireless network, thereby reducing network resource utilization.
