This work carried out a survey on Antennae Adaptive Downtilt for Long Term Evolution(LTE), towards realisation and actualising of Antennae Vectorization, this paper highlighted various contribution made by different authors, The Long Term Evolution (LTE) is one of communication standards for next-generation mobile phones, which has evolved the high-speed data communication standard HSDPA for the mainstream 3G (third generation) mobile phone system W-CDMA and beyond. A survey explained the workings of a scheduling algorithm that help enhance the capacity of an LTE system which is based on dynamically adapted Proportional Fair (PF). A new scheme was implemented to boost energy efficiency in the user equipment while retaining an overall packet wait around the latency level also for real time applications in the downlink of LTE networks, a novel algorithm of scheduling is proposed and implemented in some of the paper reviewed. Some of the proposed algorithm reduced the number of packets that has been dropped due to congestion as well as the number of lost packets due to bad channel quality, and thus enhancing the system performance. LTE Downlink 2x2 MIMO Channel B indoor model with SFBC: Design and BER analysis. The BER and SFBC were analyzed using Matlab based 2x2 MIMO orthogonal frequency division multiplexing (MIMO-OFDM) with space frequency block coding (SFBC). Benefiting from Active Antenna Systems (AAS), many active antenna technologies such as 3D beamforming and vertical sectorization could be easily implemented. Vertical sectorization can be realized by multiple antenna elements, by which two separate beams with their distinct antenna parameters are arranged to serve vertically split inner and outer cells. In our work, performance with various electrical tilt angles have been analysed and also observe the optimization space of the overlap between two vertical sectors and the gain in terms of cell capacity. In all other authors worked on how Antennae Adaptive Downtilt for Long Term Evolution(LTE) can help improve performance.
