MULTI-CELL COOPERATIVE DATA TRANSMISSION METHOD, SYSTEM AND DEVICE THEREOF

摘要

The present invention provides a multi-cell cooperative data transmission method. The method includes: the aggregate of cooperative cells of a UE (User Equipment) is obtained; a network side device allocates time and frequency resources for said UE, and determines the time domain initial locations for resource mapping of each cooperative cell according to the number of the OFDM (Orthogonal Frequency Division Multiplexing) symbols occupied by the control channels, wherein the determined time domain initial locations for resource mapping of each cooperative cell are the same; the network side device determines the available RE (Resource Element) according to the time domain initial locations for resource mapping, and each cooperative cell in turn maps the data symbols to the available REs from the time domain initial position for resource mapping in order to send them. With the present invention, the problem of resource mapping during multi-cell cooperative transmission can be solved.
