Hi hinmani,
DRS is an discovery reference signal which is formerly known as (PSS/SSS/CRS) ,these signals named as DRS in LAA. In future hey are planning to transmit system information as part of DRS.
How can eNB in Licensed Cell communicate with LAA and UE in Unlicensed Cell, So that how can it avoid the scheduling problem?
What are the messages are exchanged between UE and network to evaluate the approximate position of the UE ?
