Abstract
Better signal strength is required to provide a good signal service to the UE. For this, different methods and techniques are available, one of them is codebook type II precoding. This method has a potential to provide an amount of energy to the user in the required direction more precisely than Codebook type I. Therefore this method will be put to the test, for a given SNR range, by comparing the quality of the beamformed signal to non-beamformed signal.
Additional studies have been made about the different characteristics of the channel with simple changes in the base station with a different antenna configuration exploiting MIMO case. This will lead to have a large array gain and also spectral efficiency is increased in spatial domain.... (More)

For a better understanding of the topic and for proof of concept, it is being restricted to a single user and a single layer. (Less)
Popular Abstract
Technology has evolved in a small span of time where it has got a revolutionary change in the telecommunication and mobile phone industry. For example, earlier, we have seen that the mobile phones are being used for basic calling and messaging. After that, it has been moving towards different applications which are being added and goes on to support a lot of applications that were not supported before.
With an increase in the facilities in the new phones era, the demand of more application oriented in the mobile phone is craving for the better signal requirements and the good service quality.

For example, earlier, we have seen that the mobile phones are being used for basic calling and messaging.

With an increase in the facilities in the new phones era, the demand of more application oriented in the mobile phone is craving for the better signal requirements and the good service quality.
To match up the requirements and to satisfy the customers or users demands, a change need to be made to the services and to provide a higher and faster data rates.
The demands and requirements of the user are getting accomplished with a new technology which is 5G NR. It is codebook based. It has been implemented in LTE and LTE-A using codebook type I precoding but, major changes have been made so its directionality is more accurate leading to a better experience to the end user. A new method is being proposed, codebook type II which is in developing stages. So in this method it is being promised with much greater benefits. (Less)
