Event handling in a radio circuit

摘要

A radio circuit comprises an interface unit for communicating data and commands over a communication link between a digital baseband circuit and the radio circuit. Furthermore, the radio circuit comprises an event-scheduling unit, a local time-reference unit, a synchronization unit, and an execution-control unit. The event-scheduling unit is arranged to receive event-request commands specifying 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. Furthermore, the event-scheduling unit 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 is arranged to issue execution of each scheduled event at the scheduled time instant based on time information from the local time reference unit. The local time-reference unit is synchronized with a time-reference unit in the digital baseband circuit in response to a synchronization command, from the synchronization unit.

1. A digital baseband circuit for operation with a radio 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 digital baseband circuit and a time instant at which the specified event is to be executed, from the radio circuit; andin response to receiving an event request-command, schedule the specified event to be executed on the specified time instant; a time-reference unit that 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 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 a 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.
