  • The Signal Strength indicator of total wide-band received power within the entire channel bandwidth is called USSI.
  • Having too low or too high UL RSSI will contribute to poor quality in the network

Too low RSSI could simply mean the cell is “deaf” and cannot “listen” to any UE

  • Possible reasons are components failure, incorrect parameter settings, incorrect equipment installation, etc.

  • On the other hand, too high RSSI is equally undesirable. This case is more often seen.Due to the high noise interference, it could likely lead to frequent drop calls, call setup failure and poor voice quality. Cells with UL RSSI > -90 dBm can be considered as having high UL interference.

Hi,

In LTE, while UE makes an RRC Connection attempt and in the followed by procedures, if S1AP: Initital Context Setup Request is BLOCKED from MME to eNB, then what eNB should do ideally?

Should it do UE context release, if Initial Context Setup Request message is not received at aNB?
