A coordinated multipoint transmission/reception method, the method comprising: receiving, in a subframe, first data and first demodulation reference signal/s that are sent by a first network side device by using n antenna port/s; receiving, in the subframe, second data and second demodulation reference signal/s that are sent by a second network side device by using m antenna port/s, wherein time-frequency resources occupied by the n antenna port/s to send the first demodulation reference signal/s are different from time-frequency resources occupied by the m antenna port/s to send the second demodulation reference signal/s, n and m are positive integers, and a time-frequency resource occupied by the first data and that occupied by the second data at least partly overlap, the m antenna port/s are not quasi co-located with the n antenna port/s; and performing demodulation processing on the first data and/or the second data based on the first demodulation reference signal/s and the second demodulation reference signal/s; wherein the first data is obtained by performing layer mapping and precoding processing on a first code word by the first network side device, and the first code word is obtained by performing modulation and coding processing on first original data by the first network side device by using a first modulation and coding scheme; and the second data is obtained by performing layer mapping and precoding processing on a second code word by the second network side device, and the second code word is obtained by performing modulation and coding processing on second original data by the second network side device by using a second modulation and coding scheme. receiving, in a subframe, first data and first demodulation reference signal/s that are sent by a first network side device by using n antenna port/s; receiving, in the subframe, second data and second demodulation reference signal/s that are sent by a second network side device by using m antenna port/s, wherein time-frequency resources occupied by the n antenna port/s to send the first demodulation reference signal/s are different from time-frequency resources occupied by the m antenna port/s to send the second demodulation reference signal/s, n and m are positive integers, and a time-frequency resource occupied by the first data and that occupied by the second data at least partly overlap, the m antenna port/s are not quasi co-located with the n antenna port/s; and performing demodulation processing on the first data and/or the second data based on the first demodulation reference signal/s and the second demodulation reference signal/s; wherein the first data is obtained by performing layer mapping and precoding processing on a first code word by the first network side device, and the first code word is obtained by performing modulation and coding processing on first original data by the first network side device by using a first modulation and coding scheme; and the second data is obtained by performing layer mapping and precoding processing on a second code word by the second network side device, and the second code word is obtained by performing modulation and coding processing on second original data by the second network side device by using a second modulation and coding scheme.
