Claim of US Patent No. 9,313,825

1. An apparatus comprising:
a radio frequency (RF) component;
a first media access controller (MAC) and a first baseband (BB) configured to allow the radio frequency (RF) component to
communicate in accordance with a first wireless communication standard, wherein the first media access controller is further
configured to generate predictive data that predicts when transmission is expected by the first MAC as required by the first
baseband;

a second media access controller (MAC) and a second baseband (BB) configured to allow the radio frequency (RF) component to
communicate in accordance with a second wireless communication standard, wherein the second wireless communication standard
is different from the first wireless communication standard;

a lookup table configured to generate a baseband control signal to regulate access to the RF component by using at least the
predictive data as an input into the lookup table; and

a coexistence engine configured to arbitrate, based at least in part on the baseband control signal from the lookup table,
access of the radio frequency (RF) component to (i) the first media access controller (MAC) and the first baseband (BB) or
(ii) the second media access controller (MAC) and the second baseband (BB), wherein the first MAC is configured to provide
the predictive data to the coexistence engine.
