METHOD AND APPARATUS FOR TRANSMITTING DOWNLINK SIGNAL IN MIMO WIRELESS COMMUNICATION SYSTEM Russian patent published in 2014 - IPC H04B7/04 

FIELD: radio engineering, communication.

SUBSTANCE: invention discloses a method of receiving a downlink signal from a base station to user equipment in a multiple input multiple output (MIMO) wireless communication system, which supports dual layer transmission based on first and second antenna ports, the method comprising steps of receiving downlink control information (DCI) through a downlink control channel; and receiving downlink data through a downlink data channel. The downlink data include one or more of a first transport block and a second transport block. The downlink control information includes a new data indicator (NDI) for each of the first and second transport blocks, and if the first transport block is disabled and the second transport block is enabled, the new data indicator for the first transport block indicates an antenna port through which the second transport block is received.

EFFECT: high throughput.
