In one non-limiting, exemplary embodiment, incremental HARQ combining is performed in the DL for system information (e.g., the BCCH) without the interactive ACK/NACK responses that are an element of conventional HARQ. Instead, a number of unsolicited HARQ repeats are sent. That is, one or more HARQ incremental repeats of the BCCH frame are sent without any ACK/NACK feedback (e.g., from the UE). In one non- limiting, exemplary embodiment, a method includes: transmitting a system information message from a base station to a user equipment (201); and retransmitting the system information message as an unsolicited HARQ message from the base station to the user equipment, wherein the unsolicited HARQ message is not triggered by an indication from the user equipment (202). In further exemplary embodiments, the system information message is retransmitted as the unsolicited HARQ message in order to maintain a target BLER within a coverage area of the base station.
