摘要 |
To suppress concentration of channel quality information requests and reports in a case of discontinuously transmitting reference signals at specific resources in a time domain, and thereby preventing degradation in throughput. A transmission apparatus transmits an instruction of CSI request distributed for each reception apparatus in a subframe concurrently with or earlier than a reference signal CSI-RS to each of reception apparatuses. Each of the reception apparatuses detects the CSI request from the transmission apparatus and calculates CSI from a channel estimation value of CSI-RS received thereafter. Then, the reception apparatus identifies CSI report subframe of the own apparatus from CSI report interval information of a given time interval notified in advance, the subframe in which the CSI request is detected and transmission timing of CSI-RS, and transmits a feedback signal including CSI report value by using PUSCH at the timing of the CSI report subframe. |

1. An integrated circuit to control a process, the process comprising:
detecting a request signal for requesting a transmission of a signal; and transmitting the signal, upon detection of the request signal, in a subframe which is configured to be specific for a terminal among a plurality of terminals and which is one among a plurality of subframes that are configured using a value common to the plurality of terminals, wherein the transmitting includes transmission of the signal with a period that is specific for the terminal among the plurality of terminals, the period being from the detection of the request signal to a transmission of the signal. |
