LTE is an all IP network. The scheduling in its downlink channels is a key problem. Although many algorithms have been designed and analyzed, the QoS for the users in poor channel conditions are not enough to be ensured sometimes. We design a method to enhance the capacity of the system, which is a modifying strategy available for most existing algorithms. Our intuition is to allocate more resources to the users in poorer channel conditions without declining the QoS of the users in better channel. Simulations show that our strategy can satisfy the QoS for more users.
