Claim 0:
1. A method comprising:
transmitting, from a lower layer a Baseband Unit (BBU) to a layer of a Remote Radio Unit (RRU), via a fronthaul interface, a discovery reference signal (DRS) transmission; wherein a Control Unit (CU) of the BBU is configured to:
send the DRS signal at a time DRSth,1 (DRS Threshold1) or a time DRSth,2 (DRS Threshold2);
send an LBT DRS request at a target subframe for Listen Before Talk (LBT) sensing; and
determine if a discovery measurement timing configuration (DMTC) offset time has passed, and
if so, end the DRS transmission; and if not,
determine if a current time is DRSth,1 or DRSth,2, (Tnow=DRSth,1 or Tnow=DRSth,2?); and
if so, send the DRS transmission.
