The present document covers equipment, which may operate in frequency bands that have paired frequencies, which can be used by either equipment employing Frequency Division Duplex (FDD) or Time Division Duplex (TDD) techniques. For use with Time Division Duplex only one frequency of the frequency pair will be used and for the purpose of the present document the tx/rx separation will be zero.
The present document contains a revision to allow flexible channel spacings where block assignments have been made in accordance with ERC P-MP recommendations. Nevertheless, the channel spacing is intended be the same in down-link and up-link directions.
