Abstract
Official abstract text for this publication.
Techniques for transmitting information using cyclically shifted sequences are described. In one design, first and second sequences may be generated by cyclically shifting a base sequence by first and second amounts, respectively. The base sequence may be a CAZAC sequence, a PN sequence, or some other sequence having good correlation properties. The cyclic shifts for the first and second sequences may be determined based on a hopping pattern. A first modulated sequence may be generated based on the first sequence and a first modulation symbol and may be sent in a first time interval. A second modulated sequence may be generated based on the second sequence and a second modulation symbol and may be sent in a second time interval. Each modulated sequence may be sent on K consecutive subcarriers using localized frequency division multiplexing (LFDM).
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for wireless communication, comprising: at least one processor configured to: determine a plurality of cyclically shifted sequences to use for exchanging a first set of modulation symbols for control information in a first time slot by a user equipment (UE), each of the plurality of cyclically shifted sequences comprising K samples and being generated by cyclically shifting a base sequence by a respective amount, wherein the respective amounts a…
