TL;DR: In this paper, a base station apparatus is disclosed that is capable of communicating with user equipment used in a mobile communication system, which includes a determination unit determining whether a path loss value reported from the user equipment satisfies a predetermined condition.
Abstract: A base station apparatus is disclosed that is capable of communicating with user equipment used in a mobile communication system. The base station apparatus includes a determination unit determining whether a path loss value reported from the user equipment satisfies a predetermined condition, an instruction signal generation unit, based on a result of the determination made by the determination unit, generating an instruction signal indicating whether the user equipment should reduce a transmission power value in response to a request from an other cell to reduce the transmission power value, and a transmission unit transmitting the instruction signal to the user equipment. Further, the path loss value is derived based on an average receiving quality value and a target quality value.

TL;DR: The main challenges are to distill the essence of the method, to formalize it and to provide a framework to support its use in areas that go beyond the original domain of application.
Abstract: Platforms have become an important concept in the design of electronic systems. We present here the motivations behind the interest shown and the challenges that we have to face to make the Platform-based Design method a standard. As a generic term, platforms have meant different things to different people. The main challenges are to distill the essence of the method, to formalize it and to provide a framework to support its use in areas that go beyond the original domain of application.

TL;DR: Translations between OSL and two rights expression languages (RELs) from the DRM area make it possible to use DRM mechanisms to enforce OSL policies and enhance the interoperability of DRM mechanisms.
Abstract: We present the Obligation Specification Language (OSL), a policy language for distributed usage control. OSL supports the formalization of a wide range of usage control requirements. We also present translations between OSL and two rights expression languages (RELs) from the DRM area. These translations make it possible to use DRM mechanisms to enforce OSL policies. Furthermore, the translations enhance the interoperability of DRM mechanisms and allow us to apply OSL-specific monitoring and analysis tools to the RELs.

TL;DR: It is shown in this paper that a greedy user can substantially increase his share of bandwidth, at the expense of the other users, by slightly modifying the driver of his network adapter.
Abstract: IEEE 802.11 works properly only if the stations respect the MAC protocol. We show in this paper that a greedy user can substantially increase his share of bandwidth, at the expense of the other users, by slightly modifying the driver of his network adapter. We explain how easily this can be performed, in particular, with the new generation of adapters. We then present DOMINO (detection of greedy behavior in the MAC layer of IEEE 802.11 public networks), a piece of software to be installed in or near the access point. DOMINO can detect and identify greedy stations without requiring any modification of the standard protocol. We illustrate these concepts by simulation results and by the description of a prototype that we have recently implemented

TL;DR: In this article, a hybrid user equipment and advanced user equipment data offloading architecture is provided, which includes a backhaul link to a telecommunication network and/or the Internet.
Abstract: A hybrid user equipment and advanced user equipment data offloading architecture is provided. In this hybrid architecture, the advanced user equipment includes a backhaul link to a telecommunication network and/or the Internet. The user equipment can send and receive data through the advanced user equipment using the backhaul link.
