Title: DATA TRANSMISSION METHOD, APPARATUS, AND SYSTEM
Abstract:
The present application relates to the field of wireless communication technology, specifically to a data transmission method, apparatus, and system. Provided in the present application is a data transmission method: a UE receives data from a first access network device to which a serving cell belongs; the UE sends a decoding result of the data to the first access network device and a second access network device to which a coordinating cell belongs; and, if the decoding result is negative acknowledgment NACK signalling, then the UE receives the data retransmitted by the first access network device, and receives the data from the second access network device. The present application is designed to flexibly assist a first access network device to transmit or retransmit data to a UE by means of a second access network device, in order to improve the reliability of data transmission in a low latency scenario.
