OFDM also provides some additional benefits relevant for LTE: • OFDM provides access to the frequency domain, thereby enabling an additional degree of freedom to the channel-dependent scheduler compared to time-domain-only scheduling used in major 3G systems. • Flexible transmission bandwidth to support operation in spectrum allocations of different sizes is straightforward with OFDM, at least from a baseband perspective, by varying the number of OFDM subcarriers used for transmission. Note, however, that support of a flexible transmission bandwidth also requires flexible RF filtering, and so on, for which the exact transmission scheme is to a large extent irrelevant.
After the architecture phase, the detailed specification phase starts. It is in this phase the details for each of the identified interfaces are specified. During the detailed specification of the interfaces, the standards body may find that previous decisions in the architecture or even in the requirements phases need to be revisited. 8 The standardization phases and iterative process. 5 3GPP STANDARDIZATION 25 Finally, the testing and verification phase starts. It is usually not a part of the actual specification , but takes place in parallel through testing by vendors and interoperability testing between vendors.
It can also be used to improve the uplink coverage of TDD by relying on the possibility for continuous uplink transmission on the FDD carrier. Release 13 increased the number of carriers possible to aggregate from 5 to 32, resulting in a maximum bandwidth of 640 MHz and a theoretical peak data rates around 25 Gbit/s in the downlink. The main motivation for increasing the number of subcarriers is to allow for very large bandwidths in unlicensed spectrum as is further discussed in conjunction with LAA.
