METHOD, APPARATUS, SYSTEM AND COMPUTER PROGRAM FOR LTE CARRIER BANDWIDTH EXTENSION USING INCREASED SUBCARRIER SPACING

摘要

There is provided a method comprising providing, in dependence on a first subcarrier spacing of a first subframe structure, a second subcarrier spacing of a second subframe structure, wherein the first subframe structure has a first subframe length and at least one first cyclic prefix length and providing a second subframe length of the second subframe structure, the second subframe length comprising m symbols, wherein each symbol contains a second cyclic prefix, the second cyclic prefix length modified by a length variant.
