20150208278 | BASE STATION APPARATUS AND RETRANSMISSION CONTROL METHOD - Provided is a terminal device that is capable of improving the characteristics of a response signal having poor transmission characteristics when ARQ is utilized in communication using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. At the time of channel selection, a control unit ( | 07-23-2015 |
20150215086 | BASE STATION, TERMINAL, SEARCH SPACE SETTING METHOD AND DECODING METHOD - The invention provides a base station that does not cause the number of blind decodings to be increased and further can prevent the flexibility of resource allocation from degrading. A search space setting unit ( | 07-30-2015 |
20150215919 | INTEGRATED CIRCUIT FOR CHANNEL ALLOCATION FOR WIRELESS COMMUNICATION DEVICE - Disclosed is a base station in which the frequency usage efficiency can be improved when the communication bandwidths are asymmetric in the uplink line and the downlink line. A base station can communicate by using a plurality of downlink unit bands and a smaller number of uplink unit bands. A control unit allocates uplink resource allocation information and downlink resource allocation information to a PDCCH which is arranged in each of the plurality of downlink unit bands, and allocates a response signal to the uplink line data to a PHICH which is arranged in the same number of downlink unit bands from the plurality of downlink unit bands as there are uplink unit bands. A transmit RF unit transmits the resource allocation information or the response signal. | 07-30-2015 |
20150237638 | INTEGRATED CIRCUIT FOR TRANSMITTING AND RECEIVING REFERENCE SIGNAL IN RADIO COMMUNICATION - It is possible to provide a radio communication terminal device and a radio transmission method which can improve reception performance of a CQI and a reference signal. A phase table storage unit stores a phase table which correlates the amount of cyclic shift to complex coefficients {w1, w2} to be multiplied on the reference signal. A complex coefficient multiplication unit reads out a complex coefficient corresponding to the amount of cyclic shift indicated by resource allocation information, from the phase table storage unit and multiplies the read-out complex coefficient on the reference signal so as to change the phase relationship between the reference signals in a slot. | 08-20-2015 |
20150257171 | BASE STATION APPARATUS, MOBILE STATION APPARATUS, AND TRANSMISSION METHOD - A base station able to maintain backward compatibility with an LTE mobile station while minimizing the amount of increase in uplink scheduling information reception and demodulation/decoding processing in independent uplink/downlink cell data transmission. A wireless communication system includes a cell # | 09-10-2015 |
20150263842 | TERMINAL APPARATUS AND RESPONSE SIGNAL MAPPING METHOD - This invention relates to a terminal apparatus that can possibly reduce situations in which upstream channel data are punctured by a plurality of response signals. When having received at least one piece of downstream allocation control information corresponding to a second downstream unit band, which is other than a first downstream unit band, of a plurality of unit bands, a control unit ( | 09-17-2015 |
20150270941 | WIRELESS BASE STATION APPARATUS, WIRELESS TERMINAL APPARATUS, FREQUENCY RESOURCE ALLOCATION METHOD, AND METHOD OF FORMING TRANSMISSION SIGNAL - A wireless base station apparatus and wireless terminal apparatus with a configuration which can prevent reductions in the accuracy of channel estimation when non-contiguous band transmission and SRS transmission are employed in an uplink line. In the base station apparatus ( | 09-24-2015 |
