Title: CODING SCHEME AND EXTENDED SYNCHRONIZATION ACCESS BURST FOR EC-GSM-IOT ENHANCEMENT
Abstract:
A wireless device, a Radio Access Network (RAN) node, and various methods are described herein for improving the coverage performance of the Extended Coverage (EC)- Random Access Channel (RACH). For instance, the wireless device, the RAN node, and various methods can improve the coverage performance of the EC-RACH by utilizing a new access burst (referred to herein as Extended Synchronization Access Burst (ESAB)), a new coding scheme (referred to herein as RACH11') for the CC5 2TS EC-RACH, and/or an access burst mapping scheme for the CC5 2TS EC-RACH.
