Abstract

Systems and methods for establishing power saving data transmissions with machine-to-machine (M2M) communication capable devices and like user equipment in wireless networks are generally disclosed herein. One embodiment includes data transmission techniques to bundle small M2M data packet transmissions in an initial wireless network access process, performed before the device begins to negotiate the wireless network connection with a base station (BS). If the M2M data is successfully transmitted to the BS in the initial communication(s), then further connection does not need to occur, saving power and transmissions needed to negotiate and establish the wireless network connection. Configurations for a system, base station, and user equipment (user equipment including various M2M communication capable devices) are also described herein, including configurations for implementing the data transmission techniques.
