Abstract
Systems, methods, and apparatus adapted to transmit coexistence management interface (CxMi) messages over a multi-point serial bus are described. A method performed at a device coupled to a multi-point serial bus includes encoding CxMi state as one or more virtual general-purpose input/output (VGI) messages, and transmitting the VGI messages over the multi-point serial bus in a command code field of a datagram addressed to one or more devices coupled to the multi-point serial bus. The serial bus may be operated in accordance with an RFFE protocol SPMI protocol.

A method for communicating coexistence management interface (CxMi) information over a multi-point serial bus, comprising:
- encoding CxMi state information in a virtual general-purpose input/output (VGI) message;
- and
- transmitting the VGI message over the multi-point serial bus in a command code field of a datagram addressed to one or more devices coupled to the multi-point serial bus.
A data communication apparatus comprising:
- a bus interface configured to couple the apparatus to a multi-point serial bus;
- and
- a processor configured to:
- encode coexistence management interface (CxMi) state information in a virtual general-purpose input/output (VGI) message;
- provide the VGI message in a command code field of a datagram addressed to one or more devices coupled to the multi-point serial bus;
- and
- cause the bus interface to transmit the datagram over the multi-point serial bus.
A processor-readable storage medium having one or more instructions which, when executed by at least one processor or state machine of a processing circuit, cause the processing circuit to:
- encode CxMi state information in a virtual general-purpose input/output (VGI) message;
- and
- transmit the VGI message over a multi-point serial bus in a command code field of a datagram addressed to one or more devices coupled to the multi-point serial bus.
An apparatus operable for communicating coexistence management interface (CxMi) information over a multi-point serial bus, comprising:
- means for encoding CxMi state information in a virtual general-purpose input/output (VGI) message;
- and
- means for transmitting the VGI message over the multi-point serial bus in a command code field of a datagram addressed to one or more devices coupled to the multi-point serial bus.
