Patent ID: 8548517

Claim:
A radio circuit for operation with a digital baseband circuit, comprising: an interface unit for communicating data and commands over a communication link between the digital baseband circuit and the radio circuit; an event-scheduling unit arranged to: receive event-request commands, wherein each event-request command specifies an event to be executed in the radio circuit and a time instant at which the specified event is to be executed, from the digital baseband circuit; and in response to receiving an event request-command, schedule the specified event to be executed on the specified time instant; a local time-reference unit that generates a multi-bit time value; a synchronization unit adapted to synchronize the local time-reference unit with a time-reference unit in the digital baseband circuit in response to a synchronization command, wherein the time-reference unit in the digital baseband circuit generates a multi-bit time value; and an execution-control unit arranged to issue execution of each scheduled event at the scheduled time instant based on time information from the local time-reference unit, wherein the time instant at which the specified event is to be executed is specified as a time value to be generated by the local time-reference unit of the radio circuit or as a time value to be generated by the time-reference unit in the digital baseband circuit.
