Abstract
Official abstract text for this publication.
Extended duration cyclic prefixes with lower overhead are disclosed in which an integer multiple sequence of carriers above the nominal 300 carrier-per-25 resource blocks (RBs) definition are selected to reduce the cyclic prefix overhead below the normative 20%. Sets of durations are then provided associated with each such integer multiple sequence of carriers that allow for the combined duration of the symbol duration and extended duration cyclic prefix to result in an integer number of carriers for each RB.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of wireless communication, comprising: selecting a cyclic prefix overhead for orthogonal division multiple access (OFDMA) symbols to be transmitted in a broadcast, wherein the cyclic prefix overhead is determined based on an integer multiple of a standard carriers-to-resource blocks (RBs) definition, wherein the integer multiple comprises a number of carriers selected to result in an integer number of carriers relative to 300 carriers per 25 RBs;…
