An apparatus includes an instruction cache circuit and an instruction fetch circuit. The instruction fetch circuit is configured to retrieve, from the instruction cache circuit, a fetch group that includes a plurality of instructions for execution by a processing circuit, and to make a determination that the fetch group includes a control transfer instruction that is predicted to be taken. A target address associated with the control transfer instruction is directed to an instruction within the fetch group. The instruction fetch circuit is further configured to, based on the determination, alter instructions within the fetch group in a manner that is based on a type of the control transfer instruction.

Methods of communicating location information from a subscriber to a repeater are described. The subscriber switches from a working channel to a data revert channel, transmits a request for a periodic or one-time window to transmit an update, and determines from grant information in the response announcement the allocated window and frame before switching back to the working channel. Before the allocated time, the subscriber switches to the data revert channel, confirms whether it remains scheduled to transmit the update from a repeater announcement, and if so transmits the location update in either the current or reserved window. The announcements from the repeater contain the identity of the next window and frame and the subscriber reserved to use the window in addition to grant information. The subscribers may or may not be time-aligned and the data and data revert channels may or may not be synchronized.
