Abstract

According to an aspect, a wireless device identifies system frame numbers (SFNs) that are used for wireless transmissions that use a broadcast channel (BCH) transmission time interval (TTI), where frequency hopping cycles (FHCs) are not aligned with a cycle of the SFNs. The wireless device receives FH information indicating how the FHC used for wireless transmissions relates to the SFN cycle and identifies an SFN timing for the wireless transmissions based on the FH information.
