Closed-loop signalling method for controlling multiple transmit beams and correspondingly adapted transceiver devices

Abstract: The present invention relates to a closed-loop signaling method for controlling multiple transmit beams, comprising the steps of receiving (S21) a plurality of at least two beams from a first transceiver (Node_B) via a plurality of transmission channels at a second transceiver (UE), evaluating (S22), at said second transceiver, characteristics of said plurality of beams received at said second transceiver, determining at least one dominant beam using said characteristic, deriving (S24) control information for being fed back from said second transceiver (UE) to said first transceiver (Node_B), based on said evaluated characteristics, wherein said control information for dominant characteristics is allocated a different quantization resolution as compared to a less dominant beam (S25, S26, S27). Also, the present invention relates to a transceiver device (UE), adapted for being used in such a closed-loop signaling method for controlling multiple transmit beams.

An open ecosystem for mobile-cloud convergence

Abstract: We show how a disruptive force in mobile computing can be created by extending today’s unmodified cloud to a second level consisting of self-managed data centers with no hard state called cloudlets. These are located at the edge of the Internet, just one wireless hop away from associated mobile devices. By leveraging lowlatency offload, cloudlets enable a new class of real-time cognitive assistive applications on wearable devices. By processing high data rate sensor inputs such as video close to the point of capture, cloudlets can reduce ingress bandwidth demand into the cloud. By serving as proxies for distant cloud services that are unavailable due to failures or cyberattacks, cloudlets can improve robustness and availability. We caution that proprietary software ecosytems surrounding cloudlets will lead to a fragmented marketplace that fails to realize the full business potential of mobile-cloud convergence. Instead, we urge that the software ecosystem surrounding cloudlets be based on the same principles of openness and end-to-end design that have made the Internet so successful.

Transmission of Data Within a Communications Network

Abstract: The invention relates to methods for providing a network element 5 of a communications network with data, in particular HSDPA related data. In order to enable the transmission of user data, it is proposed that a controller 4 of the network uses a dedicated frame structure for assembling frames with said user data. The frames can then be transmitted from the controller 4 via an interface to the network element 5. In order to enable the transmission of control parameters, it is further proposed that an interface application protocol is employed which allows the controller 4 to add control parameters to control messages transmitted from the controller 4 to a network element 5 via the interface.

Accelerometer based gesture recognition using continuous HMMs

Abstract: This paper presents a gesture recognition system based on continuous hidden Markov models. Gestures here are hand movements which are recorded by a 3D accelerometer embedded in a handheld device. In addition to standard hidden Markov model classifier, the recognition system has a preprocessing step which removes the effect of device orientation from the data. The performance of the recognizer is evaluated in both user dependent and user independent cases. The effects of sample resolution and sampling rate are studied in the user dependent case.

Evolution and future directions of the ad hoc on-demand distance-vector routing protocol

Abstract: The ad hoc on-demand distance-vector (AODV) routing protocol has been designed for use in ad hoc networks, which are presently receiving wide interest within many diverse research communities. These networks represent a significant departure from traditional wired networks due to the distinguishing characteristics of both the wireless channel and mobile devices. Consequently, AODV incorporates many novel features for handling mobility, reduced capacity links, and the variable, indeterminate nature of the signaling range of wireless media. Since its initial design, AODV has evolved in a number of ways for improved performance, robustness, and better scalability. Nevertheless, we see many opportunities for continued improvement. This paper describes the current state of AODV, including its base functionality as well as optional features that improve performance and add capabilities. We also offer some direction for the continued evolution of AODV by presenting areas that can be targeted for future enhancements. Many of the described current and planned features are a result of AODVs history and evolution within the Internet engineering task force. � 2003 Elsevier B.V. All rights reserved.
