Random Access Preamble for Minimizing PA Backoff |
| 摘要 |
An example method in a user equipment comprises generating a random access preamble signal and transmitting the random access preamble signal. This generating of the random access preamble signal comprises generating a Single-Carrier Frequency-Division Multiple Access (SC-FDMA) random access preamble signal comprising two or more consecutive preamble symbol groups, each preamble symbol group comprising a cyclic prefix portion and a plurality of identical symbols occupying a single subcarrier of the SC-FDMA random access preamble signal. The single subcarrier for at least one of the preamble symbol groups corresponds to a first subcarrier frequency and the single subcarrier for an immediately subsequent one of the preamble symbol groups corresponds to a second subcarrier frequency. |

1. A method, in a user equipment, the method comprising:
generating a Single-Carrier Frequency-Division Multiple Access (SC-FDMA) random access preamble signal comprising two or more consecutive preamble symbol groups, each preamble symbol group comprising a cyclic prefix portion and a plurality of identical symbols occupying a single subcarrier of the SC-FDMA random access preamble signal, such that the single subcarrier for at least one of the preamble symbol groups corresponds to a first subcarrier frequency and the single subcarrier for an immediately subsequent one of the preamble symbol groups corresponds to a second subcarrier frequency; and transmitting the SC-FDMA random access preamble signal. |
