Abstract

The invention provides a data transmission control method, a network side device and a terminal, wherein the method comprises the following steps: the network side device maps code words on at least one data layer; the network side device maps the data layer on at least one quasi colocalization QCL group, wherein the QCL group is an antenna port group established according to a QCL relation amongvarious antenna ports; and the network side device performs data transmission based on the QCL group. With the method, the device and the terminal provided by the invention, data transmission of a multi-array antenna is realized.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a data transmission control method, network side equipment and terminal. Background technique [0002] In the current LTE system, during data transmission, the high-level transmission block is first mapped to at most two codewords, then the codewords are mapped to layers through the layer mapping module, and then the signal is mapped to the antenna port through layer-to-port mapping. The existing data transmission mechanism can support the transmission of up to 2 codewords and 8 data streams, but this method is only suitable for MIMO (Multiple-Input Multiple-Output) transmission of a single array. However, in a large-scale antenna system, multiple independent AAS (Adaptive Antenna System, adaptive antenna system) sub-array modules are likely to be used. The clock synchronization may be different, and the locations may be far apart, which cannot be used directly. Existing transmis...
