摘要： Radio resources are saved. The base station 101 determines a possibility of transmitting data to the terminal 102, and transmits the indicator indicating the possibility of transmitting the data to the terminal 102. The terminal 102 generates a mode request message for determining a coding rate and a modulation system at the base station 101, and sets a transmission frequency of the mode request message based on the indicator transmitted from the base station 101. Accordingly, the mode request message is transmitted from the terminal 102 to the base station 101 at the determined transmission frequency.

摘要： A channel monitor detects execution data quantities of first and second receiving circuits 3 and 4 which process audio and other line switching data or packet data transmitted from a plurality of base stations. Antenna weight values calculated by an antenna weight calculator 10 and supplied to the receiving circuits 3 and 4 are variably controlled on the basis of the execution data quantities of the receiving circuits. Consequently, it becomes possible to optimize the antenna weight values used for processing the data in the receiving circuits 3 and 4, hence improving the reception quality of a terminal device.

摘要： A portable terminal monitors a signal level of a short-range wireless signal from a wireless communication apparatus. If the signal level drops so low that a state of connection for short-range wireless communications cannot be maintained between the two apparatuses, use of predetermined functions of the portable terminal is limited. A short-range wireless communication facility of the portable terminal and the wireless communication apparatus move into a particular operation mode if communications do not occur therebetween at least for a predetermined time period. In monitoring the signal level of the wireless signal from the wireless communication apparatus in the particular operation mode, the portable terminal reduces a response speed at which to detect a signal level change. This causes the wireless communication apparatus to delay issuing a request for an increase in transmission power, thereby reducing unevenness of the working distance at which to alert a user to the unusual distance traveled between the two apparatuses or beyond which to limit the use of some functions of the portable terminal.

摘要： In a communication where a retransmission is attained based on a Hybrid-ARQ (Automatic repeat ReQuest) system, retransmission having no gain is reduced, and improvement of the transmission efficiency is intended. A mode determining unit 111 of a base station carries out calculation to obtain a received signal quality difference information indicative of a difference between a received signal quality at the current stage and that of a past stage at a terminal, and supplies to a control unit 112. The control unit 112 controls a power setting unit 113 based on the received signal quality difference information supplied from the mode determining unit 111, and thus a transmission power of a signal transmitted from an adaptive coding and modulation unit 13 can be controlled. The present invention can be applied to a base station of a portable telephone communication network, for example.

摘要： An X-ray imaging apparatus 1 includes an imaging device 31. Imaging device 31 has a lens 33, an imaging device 37, a circuit for driving the imaging device, and a board 53, 57 having a circuit used for processing video signals that are produced from the imaging device. These structural elements of the imaging device 31 are integrally rotatable as one body. Even when an X-ray image intensifier and an X-ray generator are revolved around the object, an output image formed on the output surface can be displayed as an upright image, if required. In addition, only the structural component by which the lens and the board 53 are connected together requires a certain level of precision, so that the cost for preparing the structural components of the apparatus is low as a whole.
