, greatly simplifying the AP design, as only one transceiver operating at one frequency band is required. In a more sophisticated case with two transceivers, a full-duplex operation could be used, where both the access link and the backhaul link operate at the same time on the same band - here it would be possible to constrain the AP operation SO that it would transmit at both the links or receive at both the links at the same time, but never transmit and receive simultaneously, removing the need for self-interference cancellation, or alternatively transmitting always on one link only and receiving on another link, eliminating the need for two transceivers, but leading to more challenging self-interference environment. In the area of multiple access there are foreseen discussions on slightly modified variants of OFDM technology, such as Non-Orthogonal Multiple Access (NOMA), as is foreseen to be studied during 2015 on the LTE-Advanced evolution track, with the example principle shown in Figure 17.5. In general, the expected development of the processing capability will allow more advanced receivers, but if the bandwidths and on the other hand processing times become shorter (to achieve lower latencies) then all the developments for the computing power will definitely be needed as well. As part of the 5G deployment, the interworking with LTE will be important. As especially with higher frequency bands the full network coverage is very costly to achieve, use of LTE to complement the coverage of 5G is foreseen. The tightest interworking would be achieved with carrier aggregation or dual connectivity-like approach, as also noted in [3]. 17.6 Expected 5G Schedule ITU-R Working Party 5D decided on the process and timeline for the development of the IMT-2020 requirements and certification of a system as IMT-2020 compliant in 2014.
