In a method of operating a device configured to communicate according to at least a first communication protocol and a second communication protocol, a time division multiplexing (TDM) pattern is obtained. The TDM pattern is defined for communication according to the first communication protocol is obtained. The TDM pattern defines communication periodicity that includes a scheduled period and an unscheduled period. A guard interval is reserved within the unscheduled period, and the unscheduled period is used for communication according to the second communication protocol. The guard interval is used to transition to an inactive state with respect to the second communication protocol.
