FIELD

This disclosure generally relates to wireless communication networks, and more particularly, to a method and apparatus for Mobile-terminated Early Data Transmission (MT-EDT) and Preconfigured Uplink Resources (PUR) in a wireless communication system.

BACKGROUND

With the rapid rise in demand for communication of large amounts of data to and from mobile communication devices, traditional mobile voice communication networks are evolving into networks that communicate with Internet Protocol (IP) data packets. Such IP data packet communication can provide users of mobile communication devices with voice over IP, multimedia, multicast and on-demand communication services.

An exemplary network structure is an Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The E-UTRAN system can provide high data throughput in order to realize the above-noted voice over IP and multimedia services. A new radio technology for the next generation (e.g., 5G) is currently being discussed by the 3GPP standards organization. Accordingly, changes to the current body of 3GPP standard are currently being submitted and considered to evolve and finalize the 3GPP standard.

SUMMARY

In accordance with the present disclosure, one or more devices and/or methods are provided. In an example from the perspective of a User Equipment (UE), the UE receives, from a network node, a paging message indicative of Mobile-terminated Early Data Transmission (MT-EDT). Responsive to receiving the paging message, the UE determines a validity of a timing parameter associated with one or more Preconfigured Uplink Resources (PUR). The UE determines, based on the validity, whether to initiate a Random Access (RA) procedure for MT-EDT or to initiate a transmission using the one or more PURs.
