摘要:
A mobile station transmits to a base station a plurality of pre-coding indicators using respective feedback schemes of a plurality of kinds of feedback schemes that can be set simultaneously by the base station. The mobile station receives from the base station a downlink signal on which pre-coders corresponding to one of the transmitted pre-coding indicators have been applied, and a pre-coder confirmation representing whether the corresponding pre-coders have been applied. The pre-coders represented by the pre-coder confirmation are associated with one of the plural feedback schemes.

A mobile communication system in which a mobile station apparatus communicates with a base station apparatus, wherein the mobile station apparatus receives an uplink data transmission permission signal, periodically transmits a first reception quality information even in case that a transmission instruction of reception quality information is not included in the uplink data transmission permission signal, transmits a second reception quality information using the physical uplink shared channel in case that the transmission instruction of reception quality information is included in the uplink data transmission permission signal, and transmits the first reception quality information and the second reception quality information in different physical formats.
摘要:
In case that an uplink grant from a base station apparatus is detected on PDCCH, a data designated by the uplink grant, channel state information measured at the time of transmission are transmitted by PUSCH as an uplink transmission signal. Then, in case that a notice that indicates retransmission is received, the data to be retransmission and the channel state information measured at the time of retransmission are transmitted by PUSCH. Accordingly, the mobile station apparatus can transmit appropriate channel state information when designated to retransmission so that the base station apparatus can make an efficient communication control (scheduling) between the base station apparatus and the mobile station apparatus that is suitable for the current channel condition.

In the case that periodical transmission of transmission signal number-of-sequence quality indicative signal cannot be performed, the number of transmission signal sequences is clarified in association with reception quality information that is generated immediately after the case, and the base station apparatus performs appropriate communication resource allocation. A mobile station apparatus has a feedback information control section 65 that generates feedback information including reception quality information, transmission signal preprocessing information and transmission signal number-of-sequence information, and a radio transmission section 51 that periodically transmits the generated feedback information to the base station apparatus, where when the radio transmission section 51 does not transmit the transmission signal number-of-sequence information with communication resources periodically allocated from the base station apparatus so as to transmit the transmission signal number-of-sequence information, the radio transmission section 51 transmits the transmission signal number-of-sequence information to the base station apparatus with communication resources enabling transmission of the feedback information allocated from the base station apparatus subsequently to the communication resources.

To provide a mobile station apparatus and a communication system that realize an efficient transmission control for a base station apparatus to allocate resources of the PUSCH with appropriate AMC mode in accordance with the channel feedback report and the scheduling request from the mobile station apparatus, and also enable rapid transmission of the uplink data (enable rapid transmission of the UL-SCH) when the mobile station apparatus transmits only the channel feedback report. A mobile station apparatus 200 applied to a system in which a base station apparatus 100 allocates the physical uplink shared channel and the mobile station apparatus 200 transmits uplink data using the physical uplink shared channel, transmits to the base station apparatus 100 the scheduling request requesting the base station apparatus 100 to allocate resources for transmitting the uplink data, using the physical uplink shared channel.
摘要:
The present invention reduces the amount of control information for specifying the transmission method for simultaneously transmitting the uplink data and the reception quality information as well as the uplink data and the ACK/NACK, reduces delay occurring in changing the transmission method, and realizes the mapping of the uplink data and the reception quality information and that of the uplink data and the ACK/NACK, in compliance with modulation scheme and coding rate of the uplink data specified by the base station apparatus. In the mobile communication system where the base station apparatus allocates, to the mobile station apparatus, resources wherein the base station apparatus transmits, to the mobile station apparatus, control information for specifying a transmission format for the mobile station apparatus to transmit information using the uplink, while the mobile station apparatus simultaneously transmits, to the base station apparatus, the uplink data and the reception quality information based on the specified transmission format in case of having received the control information from the base station apparatus.
