BASE STATION, TERMINAL, RECEIVING METHOD, AND TRANSMISSION METHOD |
摘要 |
An object of this disclosure is to improve the channel estimation accuracy without degradation of transmission quality. Control section (101) configures a predefined number of demodulation reference signals (DMRSs) for terminal (200) configured to perform repetition of an uplink signal over multiple subframes, when a coverage enhancement level corresponding to the number of the multiple subframes is smaller than a determined value, and configures, for the terminal, a number of DMRSs obtained by adding a predetermined number of DMRSs to the predefined number, when the terminal applies the repetition and the coverage enhancement level is equal to or larger than the determined value, the uplink signal being formed by time-multiplexing a data symbol with a DMRS in one subframe. Receiving section (110) receives the uplink signal including the configured number of DMRSs and transmitted from the terminal. Channel estimation section (115) performs channel estimation using the DMRS included in the received uplink signal. |
