摘要:
When a base station apparatus and a mobile station apparatus communicate with each other using a wider frequency band consists of multiple carrier components, efficient communication is achieved without increasing control information (control signal) notified from the base station apparatus to the mobile station apparatus. The base station apparatus and the mobile station apparatus communicate with each other such that each of multiple uplink carrier components corresponds to each of multiple downlink carrier components or multiple downlink carrier component groups including multiple downlink carrier components.

A communication method for sounding reference signal transmission is provided. A communication method of a user equipment in a mobile communication system in which a base station apparatus schedules a physical uplink shared channel in an uplink component carrier by using a downlink control information format, the method comprising: receiving, from the base station apparatus, the downlink control information format including first information which instructs to transmit sounding reference signal and second information which indicates the uplink component carrier in which the physical uplink shared channel is scheduled by the downlink control information format, transmitting, to the base station apparatus, sounding reference signal on the uplink component carrier indicated by the second information in case that the first information is detected.
摘要:
In a mobile station device capable of transmitting up to a predetermined number of transport blocks to a base station device on a single physical uplink shared channel, an object is to efficiently perform HARQ in case that the mobile station device receives an uplink grant that disables a part of uplink data. The mobile station device receives downlink control information transmitted by the base station device and used for scheduling the physical uplink shared channel. In case that the downlink control information indicates that a specific transport block is disabled, the mobile station device sets ACK for a HARQ process corresponding to the specific transport block.

An advertisement distributing system, advertisement distributing server, and advertisement distributing method, program and recording medium are provided for encouraging the users to buy a product in such a manner that the most suitable program video scene is selected in accordance with the advertisement distributed by an advertiser, and distributed to the users with the advertisement. An advertising video searching unit of a server, based on an advertisement ID received from a first terminal device, searches through advertisement video, extracts a video ID corresponding to the advertisement ID and outputs it to a viewing history searching unit. A viewing history searching unit determines whether the video ID has been stored in viewing history that reflects user's taste, and outputs the corresponding video ID if it is found, to a content synthesizer. The content synthesizer distributes the advertisement data and video data to the first terminal device.

In a liquid crystal television device (10) that is a wireless communication device, speaker storage sections (12a and 12b) are integrally formed with a main body section (11) containing parts such as a liquid crystal panel section (13). Although the main body section (11) is electromagnetically shielded, the speaker storage sections (12a and 12b) are not electromagnetically shielded. Antennas (15a and 15b) are provided along with speakers (14a and 14b) in speaker storage sections (12a and 12b) so as to have directions of installation different from each other by 90 degrees. This realizes a wireless communication device including an antenna structure capable of improving transmitting/receiving sensitivity in all directions.

A mobile station apparatus efficiently switches coding schemes when coding both information indicating an ACK/NACK and first control information. A mobile station apparatus 200 determines a number of bits of information on a HARQ based on a number of downlink subframes corresponding to the information on a HARQ transmitted in a certain uplink subframe, a number of set serving cells, and a transmission mode set in each serving cell, applies spatial bundling to the information on a HARQ in a case where the determined number of bits of the information on a HARQ exceeds a predetermined value, and selects one of a first coding scheme and a second coding scheme based on the number of bits of the information on a HARQ to which spatial bundling has been applied and a number of bits of a scheduling request and codes both the information on a HARQ and the scheduling request.
