Relaying operation in 3GPP LTE: challenges and solutions

Abstract: With the ever growing demand of data applications, traditional cellular networks face the challenges of providing enhanced system capacity, extended cell coverage, and improved minimum throughput in a cost-effective manner. Wireless relay stations, especially when operating in a halfduplex operation, make it possible without incurring high site acquisition and backhaul costs. Design of wireless relay stations faces the challenges of providing backward compatibility, minimizing complexity, and maximizing efficiency. This article provides an overview of the challenges and solutions in the design of relay stations as one of the salient features for 3GPP LTE advanced.

Mobile phone with music reproduction function, music data reproduction method by mobile phone with music reproduction function, and the program thereof

Abstract: A mobile phone 100 with music reproduction function comprising a reproduction unit 106 that reproduces music data and a ring tone which are recorded in a music data recording medium 105 and a ring tone, a communication unit 108 that detects an incoming call from outside and a control unit 103 that instructs the reproduction unit 106 to perform a fade-out process of reproducing music data and to perform a fade-in process of outputting a ring tone when the communication unit 108 detects an incoming call while the reproduction unit 106 is reproducing music data.

Image predictive coding method

Abstract: When dividing inputted image data to be coded into image data of a plurality of small regions which are adjacent to each other and coding the image data of an objective small region to be processed among the image data of the plurality of divided small regions which are adjacent to each other, reconstructed image data of a reproduction small region adjacent to the image data of the objective small region to be processed is used as image data of an intra-frame prediction small region of the objective small region to be processed, the image data of the intra-frame prediction small region is used as image data of an optimum prediction small region and image data of a difference small region which are differences between the image data of the objective small region to be processed and the image data of the optimum prediction small region is generated. Then, the generated image data of the difference small region is coded and outputted, and then the coded image data of the difference small region is decoded, so that the reconstructed image data of the reproduction small region is generated by adding the decoded image data of the difference small region to the image data of the optimum prediction small region.

User interface system

Abstract: A user interface system having an improved usability is provided. The user interface system comprises: an operation section (21) an operation section for receiving an instruction inputted by a user; a finger position detecting section (32) for detecting a group of first coordinate values, each indicating a current position of a fingertip, of a user, which is placed on an operation surface of the operation section; a component storing section (4) for storing component data representing a GUI (Graphical User Interface) component; an assignment section (34) for uniquely assigning the component data stored in the component storing section to each of the first coordinate values detected by the finger position detecting section (32); an image generating section (35) for generating a GUI image representing a user interface in which the GUI component represented by the component data stored in the component storing section (4) is uniquely associated with each of the first coordinate values detected by the finger position detecting section (32), in accordance with an assignment performed by the assignment section; and a display controlling section (36) for displaying the GUI image generated by the image generating section (35) on a display screen.

Image encoding method and image decoding method

Abstract: There are provided a coefficient number detector (109) for detecting the number of coefficients having a value other than 0 for each block from the coefficients generated, a coefficient number storage unit (110) for storing the number of coefficients detected, and a coefficient number encoder (111) for selecting a variable length encoding table according to the number of coefficients of the encoded block positioned around the block to be encoded and performing variable length encoding to the coefficient number by referencing the variable length encoding table which has been selected.
