Abstract
A method, NodeB and User Equipment for TDD operation in a communication system operating in TDD mode in a frequency band allocated for FDD operation. Preferably, operation is in TDD uplink and downlink mode in a first frequency band designated or normally used for FDD uplink communication, and in TDD downlink-only mode in a second frequency band designated or normally used for FDD downlink communication. The invention provides the following advantages: Provides a flexible method to deploy a time division duplex architecture in frequency division duplex spectrum. Allows flexible use of system capacity by adjusting the uplink and downlink capacity split. Removes previous FDD duplex restrictions.
