Abstract

The present invention provides a control system for multiple MIMO signals, comprising: a first base station configured to perform coordinated multipoint transmission to multiple subscriber stations, the first base station comprising: multiple antennas configured for transmitting data and control information; a transmitter coupled to the plurality of antennas, the transmitter configured to transmit a plurality of symbols in a subframe; and a controller comprising processing circuitry configured to The physical downlink shared channel (PDSCH) used by the second base station serving as the anchor cell uses the same scrambling sequence, and performs coordinated multipoint transmission with the first base station, and transmits in the same corresponding Start the transmission of multiple symbols with the same number of symbols in the resource elements of , to synchronize the transmission of multiple symbols.

Description

technical field [0001] In the field of wireless communications, the present invention generally relates to the field of wireless communications for control systems of multiple MIMO signals. Background technique [0002] Modern communications require higher data rates and performance. Multiple-input multiple-output (MIMO) antenna systems, also known as multi-element antenna (MEA) systems, achieve higher spectral efficiency of the allocated radio frequency (RF) channel bandwidth by exploiting spatial or antenna diversity of both the transmitter and receiver , or in other cases, the transceiver. [0003] In a MIMO system, each of the multiple data streams is individually mapped and modulated before being precoded and transmitted by a different physical or active antenna. [0004] The combined data stream is then received at multiple antennas of the receiver. At the receiver, each data stream is separated and extracted from the combined signal. This process is typically perf...
