CPC H04W 52/325 (2013.01) [H04W 52/146 (2013.01)] | 29 Claims |
1. A demodulation reference signal (DMRS) transmitting method, comprising:
determining a power boost value for a DMRS; and
transmitting the DMRS based on the determined power boost value, wherein the power boost value satisfies at least one of the following :
the power boost value is 0 dB when an uplink scheduling command associated with the DMRS is downlink control information (DCI) of a first format, an uplink transmission waveform is cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM), and a quantity of symbols occupied in uplink transmission is less than or equal to 2;
the power boost value is 0 dB when a radio resource control (RRC) connection is not established, an uplink transmission waveform is CP-OFDM, and a quantity of symbols occupied in the uplink transmission is less than or equal to 2; or
the power boost value is 0 dB when an uplink scheduling command associated with the DMRS is DCI, cyclic redundancy check (CRC) of the DCI is scrambled by using a temporary configure radio network temporary identity (TC-RNTI), an uplink transmission waveform is CP-OFDM, and a quantity of symbols occupied in the uplink transmission is less than or equal to 2;
wherein the first format is not 0_1.
