Now days, use of IEEE 802.22 based LTE network is growing worldwide due to its high speech capability. IEEE 802.22 is nothing but cognitive radio networks which are suffering from problems like efficient bandwidth and spectrum allocation, delay and loss ratio etc. In addition t o this there is another research problem in this domain called power efficiency. Many methods already presented in literature, however most of methods failed to achieve the tradeoff between, transmission power, transmission rate, and bandwidth. In this pap er we are extending two kinds of techniques presented such as QBC1 and QBC2 which are variants of main QBC (Queue Based Control) algorithm presented. QBC1 and QBC2 mean for different conditions of LTE network. Performance of QBC1 and QBC2 showing that QBC1 is having better Delay and Los performance as compared to QBC2, and QBC2 is having better power consumption performance as compared to QBC1. Therefore we are presenting hybrid technique which is known as HQBC (Hybrid QBC), which is main goal of improving performance in terms of los, delay, and power consumption as compared to QBC1 and QBC2. This can be achieved by using concept of multilevel queues and dynamic network adaptation.
