1. A method comprising:
- partitioning each of a plurality of frames into a plurality of sub-frames, wherein the frames are defined according to a reference system standard and wherein a cyclic prefix (CP) is one quarter of a useful symbol length;
transmitting one of the plurality of sub-frames during a pre-designated downlink transmission; and
transmitting one of the plurality of sub-frames during a pre-designated uplink transmission.

Abstract
A frame structure for support of large delay spread deployment scenarios (e.g., cellular system operation in large cell sizes or low frequency bands) is generally presented. In this regard a method is introduced comprising partitioning a radio frame into a plurality of equal-sized (or non-equal-sized) sub-frames to simplify system implementation. Other embodiments are also disclosed and claimed.
