Abstract
Disclosed is a method and apparatus to help facilitate providing of multiple Downlink Control Information (DCI) messages that separately schedule downlink communication of bearer data to a wireless communication device (WCD) in a given sub-frame, to help ensure receipt of such multiple DCI messages by the WCD. As disclosed, a base station will include in at least one such DCI message an indication that there is in the sub-frame at least one other such DCI message. When the WCD receives and reads the one such DCI message, the WCD may thereby learn from the indication that there is at least one other such DCI message in the sub-frame. The WCD may then search for and find the at least other such DCI message in the sub-frame and/or may use the indication as a basis to verify receipt of all such DCI messages in the sub-frame.
