Abstract
A wireless device may determine a coverage enhancement (CE) level (or coverage extension) by attempting to decode a received broadcast signal. The wireless device may attempt to decode a portion of the broadcast signal using a CE level that is less than the CE level of the broadcast. If the decoding attempt is successfully, the CE level may be declared as an operating CE level. If decoding is unsuccessful, the CE level may be increased decoding retried. The wireless device may continue to test-decode the broadcast signal at new (e.g., increasing) CE levels until a CE level is sufficient for a decode and is declared the operating CE level of the wireless device. In some cases, the wireless device test-decodes a broadcast channel after selecting a CE level based on a path loss measurement of a downlink signal (e.g., reference signal).
