2.7.8 LTE (MWS) Capability
The device supports a BTSIG WCI-2 MWS coexistence signaling interface. The coexistence
logical signaling is designed to enable a standard interface to allow an MWS device and a
Coexistence Controller to exchange information and support cooperative coexistence.
The WCI-2 signals carry time-critical information such as the start point of an MWS frame. The
logical coexistence signaling architecture also includes transparent data messaging and vendor
specific data messaging mechanism to enable passing information to and from the collocated
MWS device and Coexistence Controller when long latency (tens of milliseconds) cannot be
tolerated.
Further information
Coexistence Signals
The logical signals assist in time alignment, protecting MWS from interference and maximizing
the usability of the Bluetooth radio.
