Abstract
A wireless communication system operates in a combined FDD and TDD mode. During a first time period, data may be transmitted at a first frequency band and received at a second frequency band. During a second time period, data is transmitted at the second frequency band and received at the first frequency band. The first and second time periods may be of identical durations, thereby creating a 50% duty cycle. When the base station operates with multiple frequency bands, spatial processing parameters such as the spatial signature or copy weights of the mobile stations may be collected in all frequency bands, thereby allowing the full processing advantage of adaptive antenna.
