In a user equipment (UE) of a wireless communication network, the UE configured to operate in half duplex frequency division duplexing (HD-FDD) mode in the network the UE configures for one or more conditions under which the UE will transmit under HD-FDD mode in uplink (UL) to the network and not receive in downlink (DL) from the network during a Random Access Channel (RACH) procedure. The UE determines whether the configured one or more conditions obtain for a particular RACH procedure. Upon determining that the configured one or more conditions obtain for the particular RACH procedure, the UE transmits under HD-FDD mode in UL during the particular RACH procedure in accordance with the configured one or more conditions.
