20130142153 | WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD - A wireless communication apparatus is capable of improving communication efficiency by reducing the amount of control information transmitted. A channel quality information extraction section extracts CQI's from a received signal. An allocation control section allocates subcarriers for every communication terminal apparatus and selects a modulation scheme in such a manner that required transmission rate is satisfied for each communication terminal apparatus based on required transmission rate information, etc. and CQI's for communication terminal apparatus of each user. A required subcarrier number determining section decides the number of subcarriers allocated to every communication terminal apparatus so as to satisfy the required transmission rate for each communication terminal apparatus. A required subcarrier number information generating section generates information for the number of subcarriers allocated to every communication terminal apparatus. A subcarrier allocation section allocates packet data to selected subcarriers. Modulating sections adaptively modulate packet data allocated to each subcarrier. | 06-06-2013 |
20130322340 | BASE STATION APPARATUS AND RADIO COMMUNICATION METHOD FOR RECEIVING INFORMATION INDICATIVE OF CHANNEL QUALITY FROM MOBILE STATION - A wireless communication method and apparatus are provided for selecting quality-reporting sub-carrier bands based on sub-carrier band quantity information received from a base station. The method includes generally four steps. First, from a base station, information indicating quantity of sub-carrier bands is acquired. Second, channel quality of each of a plurality of sub-carrier bands within a communication band is measured from a received signal. Third, sub-carrier bands are selected from the plurality of sub-carrier bands, wherein quantity of the selected sub-carrier bands corresponds to the quantity of sub-carrier bands indicated by the acquired information. Fourth, information indicating channel quality of the selected sub-carrier bands is reported to the base station. | 12-05-2013 |

20140254571 | RANDOM ACCESS METHOD, RADIO COMMUNICATION TERMINAL DEVICE, RECEIVING METHOD, AND BASE STATION APPARATUS - Random access technology is provided for establishing an individual channel between a radio communication terminal device and a base station device in a short time and a radio communication terminal device executing the random access method. A RACH sub-channel allocation unit allocates a transmission packet input from a replication unit to an arbitrary sub-carrier at the RACH arbitrary time slot at random. An allocation unit judges whether an overlap is generated in the allocation result obtained by the RACH sub-channel allocation unit. | 09-11-2014 |
