Assignee: QORVO US, INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A multi-radio apparatus comprising:
a first transceiver circuit configured to communicate a first radio frequency (RF) signal in a shared RF medium;
a standard-defined coexistence interface coupled to the first transceiver circuit; and
a second transceiver circuit coupled to the standard-defined coexistence interface and configured to:
assert a medium access request via the standard-defined coexistence interface for communicating a second RF signal in the shared RF medium in response to detecting a preamble of an incoming packet in the second RF signal;
set a predetermined time-out timer immediately when the medium access request is granted, wherein the predefined time-out timer is longer than a temporal duration required for completing one or more of:
receiving the incoming packet in the second RF signal; and
receiving a medium access control (MAC) layer retransmission of the incoming packet; and

de-assert the medium access request via the standard-defined coexistence interface in response to an expiration of the predefined time-out timer.
