Method for simultaneous communication over fdd and tdd networks
A recently granted patent (Publication Number: US11903005B2) discloses a method for operating a station to enable simultaneous communication over two different Radio Access Networks (RANs) using different carrier signals. The method involves aligning the timing of transmissions from the station over the first Frequency Division Duplex (FDD) RAN to match the timing for transmissions over the second Time Division Duplex (TDD) RAN. This alignment is achieved by delaying or advancing Receipt Acknowledgement message transmissions in the first RAN compared to a fixed timing, allowing for efficient communication without interference.
Furthermore, the patent describes the configuration of the station for Carrier Aggregation (CA) or Dual Connectivity (DC) functionality, where a control signal instructs the station to align the timing of transmissions between the two RANs. The method also addresses harmonic interference caused by transmissions on the first carrier signal to reception on the second RAN, with the frequency of the second carrier signal being a harmonic of the first carrier signal. The patent covers various scenarios involving different Radio Access Technologies (RATs) and provides a detailed process for configuring the station for optimal simultaneous communication over the two RANs.
