<p>A radio circuit (20) for operation with a digital baseband circuit (10). The radio circuit (20) comprises an interface unit (165) for communicating data and commands over a communication link (30) between the digital baseband circuit (10) and the radio circuit (20). Furthermore, the radio circuit (20) comprises an event-scheduling unit (180), a local time-reference unit (170), a synchronization unit (175), and an execution-control unit (185). The event-scheduling unit (180) is arranged to receive event-request commands, wherein each event-request command specifies an event to be executed in the radio circuit (20) and a time instant at which the specified event is to be executed, from the digital baseband circuit (10). Furthermore, the event-scheduling unit (180) is arranged to, in response to receiving an event request-command, schedule the specified event to be executed on the specified time instant. The execution-control unit (185) is arranged to issue execution of each scheduled event at the scheduled time instant based on time information from the local time reference unit (170). By means of the synchronization unit (175), the local time-reference unit (170) is synchronized with a time-reference unit (14) in the digital baseband circuit (10) in response to a synchronization command. A communication circuit (5) comprising the radio circuit (20), a method of operating the radio circuit (20), a computer program product, and a computer readable medium are also disclosed.</p> |
