Abstract: Disclosed aspects relate to methods and apparatus for coexistent radio frequency (RF) systems in a wireless device. Control of a wireless device includes detecting when a turn on signal is issued to a first radio system, and then controlling the second radio system to either modify the operation of receiver circuitry in the second radio system to protect components within that system, or modify transmit circuitry to stop transmissions for protecting components within one radio system potentially affected by transmission from the other radio system in the wireless device. Disclosed also is monitoring of transmission states of the radio systems based on reading messages between the first and second radio systems and issuing a notification message based thereon such that one of the radio systems may suspend monitoring of a transmit channel for permission to transmit in order to reduce power consumption due to such monitoring of the channel.

Abstract: Slave initiated interrupts for a communication bus are disclosed. In one aspect, the communication bus is a radio frequency front end (RFFE) bus, and a slave is allowed to indicate to a master on the RFFE bus that the slave has an interrupt condition. On receipt of a slave initiated interrupt, the master may initiate a polling sequence to determine which of a plurality of slaves associated with the RFFE bus initiated the interrupt and process the interrupt accordingly. Continuing the exemplary aspect, the slave may indicate the interrupt condition to the master by driving a clock line of the RFFE bus to a non-idle state. The master may detect this manipulation of the clock line and initiate the polling sequence.

Abstract: Methods and apparatuses are described that facilitate the communication of data between a transmitter and a receiver across a serial bus interface. In one configuration, a transmitter generates a datagram based on a register address, detects whether the register address is within a high data rate (HDR) access address range, and sends a payload of the datagram to the receiver according to a HDR mode when the register address is within the HDR access address range. In another configuration, the transmitter generates a datagram including at least a command field and a data field, sends the command field to the receiver according to a single data rate (SDR) mode, wherein the command field indicates a transition to a high data rate (HDR) mode for sending the data field, and sends the data field to the receiver according to the HDR mode.

Abstract: A method for classifying radio frequency front-end (RFFE) devices. The method includes enumerating a radio frequency front-end (RFFE) slave device according to at least one classifier bit within the RFFE slave device. The method also includes adjusting an RFFE control interface of an RFFE master device according to slave device configuration information determined from the at least one classifier bit within the RFFE slave device.
