Pseudo-random sequence mapping in wireless communications |
| 摘要 |
Systems and methodologies are described that facilitate scrambling of downlink reference signals utilizing a pseudo-random sequence (PRS) corresponding to a primary synchronization code (PSC) and secondary synchronization code (SSC) combination. In an aspect, a method includes receiving a scrambled downlink reference signal, determining a pseudo-random sequence based on received PSC and SSC, and descrambling a portion of subframes of the downlink reference signal according to the pseudo-random sequence and a determined cyclic prefix length for one or more of the portion of subframes. |

1. A method for wireless communications, comprising:
receiving a scrambled downlink reference signal; determining a pseudo-random sequence based on received primary and secondary synchronization codes that directly map to the pseudo-random sequence; and descrambling a portion of subframes of the scrambled downlink reference signal according to the pseudo-random sequence and a determined cyclic prefix length for one or more of the portion of subframes. |
