Abstract
Embodiments of the present invention provide a communication terminal apparatus and a method. The communication terminal apparatus includes: a switch unit, a radio frequency unit, and a controller. The controller controls the switch unit to perform switching according to a preset ratio of uplink signal time duration resources to downlink signal time duration resources. The embodiments of the present invention can solve a problem of inflexible uplink and downlink time duration resource configuration.
