摘要： A transmission path state estimation unit estimates a state of a transmission path to a wireless terminal based on a DRS (Demodulation Reference Signal) included in uplink user data received from the wireless terminal when a re-sending request is received after transmission of an SRS is stopped. A transmission unit forms directivity of a plurality of antennas based on the estimated state of the transmission path and transmits downlink user data.

摘要： An eNB1-1 transmits an RRC Connection Reconfiguration message to UE2-1 to UE2-3, in which SRS parameters and an application timing parameter are set, the SRS parameters differ for each of the UE2-1 to the UE2-3 and the application timing parameter is common in the UE2-1 to the UE2-3. The UE2-1 to the UE2-3 receive the RRC Connection Reconfiguration message and recognize the SRS parameters and the application timing parameter set in the message. Furthermore, when an application timing of the SRS parameter arrives, the UE2-1 to the UE2-3 apply the SRS parameter to the SRS and transmit the SRS.
