First Claim
1. A method for wideband coverage enhancement (WCE) in a wireless network, the method comprising;
- determining, by controller logic of a base station operable in the wireless network, if a legacy system information block (SIB) message payload size is larger than a WCE SIB message payload size by a threshold amount, wherein the legacy SIB message payload comprises system information to aid one or more UE operable in the wireless network implementing a non wideband coverage enhancement communication mode and the WCE SIB message payload comprises system information to aid one or more UE operable in the wireless network implementing a wideband coverage enhancement communication mode;
if the legacy SIB message payload size is larger than the WCE SIB message payload by the threshold amount, transmitting, using a transmit processor of the base station, a multiple subframe coverage enhancement (CE) discovery reference signal (DRS) having the legacy SIB message payload and the WCE SIB message payload independently encoded therein; and
if the legacy SIB message payload size is not larger than the WCE SIB message payload by the threshold amount, transmitting, using a transmit processor of the base station, the multiple subframe CE DRS having the legacy SIB message payload and the WCE SIB message payload jointly encoded therein.

Abstract
Configurations of system information blocks providing cell access information supporting wideband coverage enhancement in wireless communication networks are disclosed. Embodiments encode and transmit information elements for both a legacy system information block and a wideband coverage enhancement system information block in a multiple subframe discovery reference signal configuration. For example, embodiments may utilize a two subframe CR-DRS configuration in which a WCE SIB-MF1 message payload is encoded and transmitted independently with respect to a legacy SIB-MF1 message payload. Additionally, or alternatively, embodiment may utilize a two subframe CR-DRS configuration in which both a legacy SIB-MF1 message payload and a WCE SIB-MF1 message payload share the same DRS subframe payload by jointly encoding the legacy SIB-MF1 and WCE SIB-MF1 messages.
