Abstract: Systems, methods, and apparatus are described that provide for communicating coexistence messages over a multi-drop serial bus. A data communication method includes configuring a common memory map at each of a plurality of devices coupled to a serial bus, receiving at a first device coupled to the serial bus, first coexistence information directed to a second device coupled to the serial bus, generating at the first device, a coexistence message that includes the first coexistence information, and transmitting the coexistence message to the second device over the serial bus. The first coexistence information in the coexistence message may be addressed to a location in the common memory map calculated based on a destination address associated with the first coexistence information and a unique identifier of the first device.

Abstract: A method, an apparatus, a receiver component, and a computer program product for wireless communication are provided. The apparatus may receive a first portion of a communication from a transmitter component via a wireless coexistence interface between the receiver component and the transmitter component; determine at least one of a radio access technology (RAT) identifier or a transmit operation based at least in part on the first portion of the communication; and at least one of: process a second portion of the communication based at least in part on the RAT identifier; or perform the transmit operation. Numerous other aspects are provided.

Abstract: In a device comprising a serial bus and a plurality of devices, register/address mappings and/or unique group identifiers are used to convey additional information in messages/datagrams over the serial bus without explicitly sending such information in the message/datagram. Such register/address mappings may be done beforehand, and in conjunction with group-specific identifiers, may reduce transmission latency by keeping the size of the messages/datagrams small. Since all devices on the serial bus have prior knowledge of such register/address mappings and/or group-specific identifiers, recipient devices are able to infer information from the group-specific identifiers and/or register/address sent in each message/datagram that is not explicitly sent within such message/datagram.
