Explain The Difference Between Reference Signal (rs) And Synchronizat

1.	Explain The Difference Between Reference Signal (rs) And Synchronization Signal (ss) In The Lte? Also Mention Types Of Rs And Ss?
Answer» REFERENCE signal (RS) is used as pilot SUBCARRIER in LTE SIMILAR to other broadband WIRELESS technologies such as WLAN, WIMAX etc. Synchronization signal is used as preamble sequence in LTE for synchronization purpose. RS is used for channel estimation and tracking. SS are of two types viz. P-SS and S-SS. P-SS is used for initial synchronization. S-SS is used for frame boundary determination. RS are of two types viz. Demodulation RS (DRS) Sounding RS (SRS). DRS is used for sync and channel estimation purpose. SRS is used for channel quality estimation purpose. DRS is used in both the uplink and downlink, while SRS is used only in the uplink.
