while performing handover ue needs to scan neighbour cells for handover ue usually don't have access to all cells to measure(measurement event/report) then how come ue will know which cells it needs to measure?
Hi, This will be communicated to UE via RRC mesaage. Measurent configuration mesaage will contain neighbouring cell information. e.g cellid earfcn etc
DL data will be decoded by number of UE's under a eNB ,but how a particular UE will know the dl data coming is to that UEonly at PHY level because the CRNTI will be at MAC header
in contention based RACH procedure ENB will use CSI field RAR as reservd then How UE will get to know weather to send apriodic CSI to ENB or not?
