TL;DR: This paper studies resource allocation for a multiuser MECO system based on time-division multiple access (TDMA) and orthogonal frequency-divisionmultiple access (OFDMA), for which the optimal resource allocation is formulated as a mixed-integer problem.
Abstract: Mobile-edge computation offloading (MECO) off-loads intensive mobile computation to clouds located at the edges of cellular networks. Thereby, MECO is envisioned as a promising technique for prolonging the battery lives and enhancing the computation capacities of mobiles. In this paper, we study resource allocation for a multiuser MECO system based on time-division multiple access (TDMA) and orthogonal frequency-division multiple access (OFDMA). First, for the TDMA MECO system with infinite or finite cloud computation capacity, the optimal resource allocation is formulated as a convex optimization problem for minimizing the weighted sum mobile energy consumption under the constraint on computation latency. The optimal policy is proved to have a threshold-based structure with respect to a derived offloading priority function , which yields priorities for users according to their channel gains and local computing energy consumption. As a result, users with priorities above and below a given threshold perform complete and minimum offloading, respectively. Moreover, for the cloud with finite capacity, a sub-optimal resource-allocation algorithm is proposed to reduce the computation complexity for computing the threshold. Next, we consider the OFDMA MECO system, for which the optimal resource allocation is formulated as a mixed-integer problem. To solve this challenging problem and characterize its policy structure, a low-complexity sub-optimal algorithm is proposed by transforming the OFDMA problem to its TDMA counterpart. The corresponding resource allocation is derived by defining an average offloading priority function and shown to have close-to-optimal performance in simulation.

02 Oct 2001TL;DR: In this paper, a method for transmitting data in a data communication system having a mobile terminal and a transmitting/receiving terminal is described, where a first connection request and a telephone number of the receiving data terminal by the transmitting data terminal to the mobile terminal is transmitted.
Abstract: A method for transmitting data in a data communication system having a mobile terminal and a transmitting/receiving terminal is enclosed. The method includes the steps of establishing a voice communication channel between the mobile terminal and a receiving data terminal in the data communication system set to a Voice mode, setting the data communication system to a Data mode without disconnecting the voice communication channel by transmitting a first connection request and a telephone number of the receiving data terminal by the transmitting data terminal to the mobile terminal, establishing a data communication channel between the transmitting and receiving data terminals, and transmitting data to the receiving data terminal through the data communication channel. By sending a receiving side telephone number to the mobile terminal together with a connection request signal (ATD command) as shown in the data communication method according to the present invention, a user can transmit or receive data more conveniently during the wireless conversation. The mode of the communication system can simply be converted from a Voice mode to a Data (Fax) mode by transmitting a ATD command together with a receiving side telephone number so that it can provide a substantial convenience to a user when transmitting or receiving data during the wireless phone conversation.

05 May 2011TL;DR: In this article, a 3D user interface using 3D objects arranged in a virtual 3D space is presented, which enables a user to manipulate a mobile terminal with a new visual effect.
Abstract: A mobile terminal and controlling method thereof are disclosed. The present invention includes displaying a 3D user interface including at least one 3D object on a display unit, selecting at least one stereoscopic region from the 3D user interface by a first input via a user input unit, displaying at least one polyhedron corresponding to each of the selected at least one region on the display unit, and changing a display state of each of the at least one polyhedron to correspond to a second input via the user input unit, wherein the step of changing the display state is performed to enlarge, reduce, rotate or scroll the at least one polyhedron according to the second input. Accordingly, the present invention provides a 3D user interface using a 3D object arranged in a virtual 3D space, thereby facilitating a user to manipulate a mobile terminal with a new visual effect.

TL;DR: Some of the deployment scenarios in which CoMP techniques will likely be most beneficial and an overview of CoMP schemes that might be supported in LTE-Advanced given the modern silicon/DSP technologies and backhaul designs available today are discussed.
Abstract: 3GPP has completed a study on coordinated multipoint transmission and reception techniques to facilitate cooperative communications across multiple transmission and reception points (e.g., cells) for the LTE-Advanced system. In CoMP operation, multiple points coordinate with each other in such a way that the transmission signals from/to other points do not incur serious interference or even can be exploited as a meaningful signal. The goal of the study is to evaluate the potential performance benefits of CoMP techniques and the implementation aspects including the complexity of the standards support for CoMP. This article discusses some of the deployment scenarios in which CoMP techniques will likely be most beneficial and provides an overview of CoMP schemes that might be supported in LTE-Advanced given the modern silicon/DSP technologies and backhaul designs available today. In addition, practical implementation and operational challenges are discussed. We also assess the performance benefits of CoMP in these deployment scenarios with traffic varying from low to high load.
