Methods and apparatus for simultaneous multiprotocol processing of different radio standards using a common pipeline

An apparatus, comprising:

• a wireless interface configured to receive radio data symbols in accordance with a plurality of radio protocols;
• a timing circuit configured to receive a plurality of synchronization signals and generate an internal time reference that is selectively synchronized to the plurality of synchronization signals;
• a controller configured to receive a plurality of job requests including a first job request describing reception of data using a first radio protocol of the plurality of radio protocols and a second job request describing reception of data using a second radio protocol of the plurality of radio protocols;
• a scheduler configured to generate event queues based on the internal time reference, the event queues including:
• a queue of (i) first radio data symbols associated with the first job request, and (ii) first wait cycles interspersed with the first radio data symbols and having wait intervals corresponding to a transmit interval of the first radio protocol;
• and
• a queue of (i) second radio data symbols associated with the second job request, and (ii) second wait cycles interspersed with the second radio data symbols and having wait intervals corresponding to a transmit interval of the second radio protocol, wherein the transmit interval of the second radio protocol is shorter or longer than the transmit interval of the first radio protocol;
• and
• an event processor configured to process the event queues to control the wireless interface to receive the first and second radio data symbols and wait during the first and second wait cycles.
