1. A User Equipment (UE) comprising:
one or more processors; and
at least one memory, wherein the at least one memory stores instructions that, when executed by the one or more processors, cause the one or more processors to:
cause a Radio Resource Control (RRC) layer to determine, using a pre-configured uplink resource, to transmit uplink data in an RRC idle state without performing a random access procedure;
cause a Medium Access Control (MAC) layer to transmit the uplink data to a base station using the preconfigured uplink resource; and
cause the MAC layer to determine and indicate to the RRC layer that the transmission of the uplink data on the preconfigured uplink resource has failed in response to determining that a response for the transmission of the uplink data has not been received from the base station during a time duration, wherein
when the UE receives an RRC connection release message containing a configuration of the pre-configured uplink resource, a pre-configured uplink resource validity timer is started, and
the RRC layer determines, using the pre-configured uplink resource, to transmit the uplink data in the RRC idle state without performing the random access procedure when (i) the pre-configured uplink resource validity timer is running and (ii) a reference signal received power (RSRP) does not exceed a configured threshold.
