Data processing method, base station, and receiving device

A data processing method, comprising:

• obtaining, by a receiving device, a demodulation pilot pattern in a transmission time unit, wherein the demodulation pilot pattern comprises a first demodulation pilot pattern of a first codeword and a second demodulation pilot pattern of a second codeword;
• the first demodulation pilot pattern indicates a time-frequency resource of each OFDM symbol in a first set, and the second demodulation pilot pattern indicates a time-frequency resource of each OFDM symbol in a second set;
• and a modulation and coding scheme (MCS) indication value of the first codeword is greater than an MCS indication value of the second codeword;
• and
• receiving, by the receiving device, a pilot signal based on the demodulation pilot pattern, wherein the pilot signal is sent by a base station after being mapped by the base station to a time-frequency resource based on a demodulation pilot map;
• and a transmission time of a first OFDM symbol in the first set is before a transmission time of a first OFDM symbol in the second set, the first OFDM symbol in the first set is an OFDM symbol with an earliest transmission time in the first set, and the first OFDM symbol in the second set is an OFDM symbol with an earliest transmission time in the second set.

A base station, comprising:

• a processor configured to obtain a demodulation pilot pattern in a transmission time unit, wherein the demodulation pilot pattern comprises a first demodulation pilot pattern of a first codeword and a second demodulation pilot pattern of a second codeword, the first demodulation pilot pattern indicates a time-frequency resource of each orthogonal frequency division multiplexing (OFDM) symbol in a first set, and the second demodulation pilot pattern indicates a time-frequency resource of each OFDM symbol in a second set, and a modulation and coding scheme (MCS) indication value of the first codeword is greater than an MCS indication value of the second codeword;
• and
• a transceiver configured to:
• map a pilot signal to a time-frequency resource based on the demodulation pilot pattern, and
• send the pilot signal to a receiving device, wherein a transmission time of a first OFDM symbol in the first set is before a transmission time of a first OFDM symbol in the second set, the first OFDM symbol in the first set is an OFDM symbol with an earliest transmission time in the first set, and the first OFDM symbol in the second set is an OFDM symbol with an earliest transmission time in the second set.
