摘要 |
<p>The signal has an additional OFDM high-speed downlink packet access (HS-DPA) line for distribution of broadband data, and presenting a sub-frame structure. The start of a sub frame of the line is off-centered from a non-zero duration time interval (delta t) relative to an instant (t 0) found on a main UMTS line to permit synchronization at the sub-frame level of the additional line, by detection of the instant and addition of the interval. Independent claims are also included for the following: (A) a process for synchronization of the additional channel associated to a symmetric bidirectional main channel (B) a base station of a cellular telephony system.</p> |
