The purpose of RRC CONNECTION RE-ESTABLISHMENT procedure is to re-establish the RRC connection, which involves the resumption of SRB1 operation and the re-activation of security (without changing algorithms).
Read moreWhat is RRC connection setup?
The RRC CONNECTION SETUP message is used to establish SRB1 . It contains configuration information for SRB1. This allows subsequent signaling to use the DCCH logical channel. The configuration for SRB1 can be a specific configuration or the default configuration.

The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station.

RRC Connected State LTE UE monitors control channels associated with shared data channel to determine if the data is scheduled for it or not . The Channel quality feedback information is also provided by the UE after measurements. It also performs neighbor cell measurements of UTRAN,EUTRAN and GSM cells.
Read moreWhat is resource grid in LTE?
– A resource grid is characterized by one subframe in time domain and full carrier bandwidth in the frequency domain . – There are a set of resource grids per transmission direction (uplink or downlink).
Read moreWhat is SSF in LTE?
A Special subframe has three past DwPTS(Downlink Pilot Time Slot),GP (Guard Period) and UpPTS (Uplink Pilot Time Slot) and all of these have configurable lengths while the sum of the lengths has to be 1 ms or 14 symbols.
Read moreWhat is DwPTS?
DwPTS. The DwPTS is used for downlink synchronization . During the cell search procedure, the UE acquires the timing of the DwPTS by correlating with the SYNC-DL code transmitted in the DwPTS. The UE must identify which SYNC-DL sequence is used out of 32 SYNC-DL possible sequences.
