Abstract: Methods, systems, and devices for wireless communications are described. The method includes operating in narrowband communications, receiving a message in a physical broadcast channel via the narrowband communications, identifying a message type of the message in the received physical broadcast channel, decoding a master information block in the physical broadcast channel based on the identified message type, and identifying a search space for a physical downlink control channel for receiving a system information block based on the decoded master information block. In some cases, the method includes coexisting with an additional device operating in wideband communications and identifying an indication in the decoded master information block that indicates an additional master information block is to be transmitted.
