Data transmission method and apparatus, data receiving method and apparatus, communication device, communication system, and storage medium

摘要

A method and apparatus for transmitting data, a method and apparatus for receiving data, a communication device, a communication system and a storage medium are provided. The transmit and receive point (TRP) divides data scheduled by one downlink control information (DCI) into N data parts, and transmits the N data parts to the receiving side, where N ≥ 1. Whether the value of N and the N data portions for N > 1 are correlated is determined by at least one of the following scheduling information: transmit configuration indicator (TCI) field, demodulation reference signal (DMRS) port indication Now, modulation and coding scheme (MCS), redundancy version (RV) or new data indicator (NDI). After receiving the N data parts transmitted by the TRP, the receiving side determines whether the N data parts are correlated, according to at least one of TCI, DMRS port indicator, MCS, RV, or NDI. .
