If the relevant end-user 5G era dawns from 2020, LTE will have a very large distribution and co-exist next to 5G. But Huawei wants to realize not only parallel to LTE 5G, but even in the same frequency spectrum in the divided frequency blocks. The idea was the producer for MWC 2017th
5G, LTE and 3G will coexist for a long time
The new mobile radio standard 5G will coexist for a long time in addition to LTE, the German Telekom sees even 3G until 2020 and beyond next 5G in use. That said Deutsche Telekom CEO Timotheus Höttges under the MWC.
Allocation of frequency blocks for 5G and LTE
For Huawei 5G is not necessarily limited to the previously regarded as a standard frequency range above 6 GHz. The network division of the Group, which invested as mobile equipment currently heavily in research of new technologies for 5G shows the trade fair in Barcelona, a concept in which the spectrum below 3 GHz, ie the classical LTE frequencies used for 5G become.
However, this does not take place exclusively on the used therein frequency blocks (carriers), but in the assigned areas of the frequency blocks, which are currently being used not for LTE. A mobile operator can thereby define himself as he distinguished the carrier management.
The graph shown here originates from Qualcomm and showing in the right of the two images in the height of four antennas of a MIMO configuration and the various frequency blocks in width for the Carrier Aggregation (CA). The black marked by computer base range of the frequency blocks could be used in the example of Huawei for 5G and the other region for LTE.
Note: The custom graphic shown by Huawei at the booth could not therefore be photographed, image manipulation other graphics.
minimize unused resources on the network
The concept shown by Huawei could increase the efficiency of existing infrastructure and minimize unused resources on the network. To known standards, the manufacturer but does not hold at least according to the current definition therefore, a concrete example when an operator does not yet exist for it. The German Telekom goes for all mobile operators of aggregated costs in the amount of 300 to 500 billion euros for the nationwide development of 5G in Europe. Huawei’s new approach could cost transitional reduce slightly.
