Transmit diversity is by default Transmission mode in RRC connection setup. It may or may not change in Reconfiguration to TM3 or TM4 based different transmission mode satisfied conditions.
why eNB sends rrc reconfiguration to connected UE when we add or modify inter frequency for SIB5 on eNB
As i understand, UE reads SIB5 after reading paging in idle mode. Why RRC reconfig is required at this time ?
