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: Access terminals are adapted to regulate power in wireless receiver circuits. In one example, access terminals include a communications interface with at least one wireless receiver circuit. A processing circuit coupled with the communications interface can receive a transmission during a Frequency Correction Channel (FCCH) frame. Following the received transmission, at least a portion of the receiver circuit may be powered down. A determination may also be made whether the received transmission was reliable. The receiver circuit can subsequently be powered up, and another transmission can be received on a subsequent channel. When the received transmission was sufficiently reliable, the other transmission may be a transmission during a Synchronization Channel (SCH) frame. When the received transmission is not sufficiently reliable, the other transmission may be another transmission received during a subsequent Frequency Correction Channel (FCCH) frame. Other aspects, embodiments, and features are also claimed and described.

Abstract: Systems, methods, and apparatus for improving throughput of a serial bus are described. A method performed at a device coupled to a serial bus includes detecting a transition in signaling state of a first wire of the serial bus while a first pair of consecutive bits is being received from the first wire of the serial bus, determining that no transition in signaling state of the first wire occurred while a second pair of consecutive bits is being received from the first wire, defining bit values for the first pair of consecutive bits based on direction of the transition in signaling state detected while the first pair of consecutive bits is being received, and sampling the signaling state of the first wire while the second pair of consecutive bits is being received to obtain a bit value used to represent both bits in the second pair of consecutive bits.

Abstract: Methods and apparatuses are described that facilitate data communication between a first slave device and a second slave device across a serial bus interface. In one configuration, a master device receives, from a first slave device, a request to send a masked-write datagram to a second slave device via a bus, wherein the masked-write datagram is addressed to a radio frequency front end (RFFE) register of the second slave device. The masked-write datagram includes a mask field identifying at least one bit to be changed in the RFFE register and a data field providing a value of the at least one bit to be changed in the RFFE register. The master device detects whether the first slave device is authorized to send the masked-write datagram to the second slave device and permits the first slave device to send the masked-write datagram to the second slave device if authorization is detected.

Abstract: Systems, methods, and apparatus for data communication are provided. An apparatus maybe configured to generate a mask field in a packet to be transmitted through an interface to a slave device, the mask field having a first number of bits, provide a control-bit field in the packet, the control-bit field having a second number of bits, where the second number of bits is less than the first number of bits, and transmit the packet through the interface. The packet may be addressed to a control register of the slave device. The control register may have the first number of bits. Each bit in the control-bit field may correspond to a bit of the control register that is identified by the mask field.

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 16-bit address and a mask-and-data pair burst length, the 16-bit address including a most significant byte (MSB) and a least significant byte (LSB), compares the MSB to a receiver base address maintained in a shadow register, compares the mask-and-data pair burst length to a receiver masked-write burst length maintained in the shadow register, and sends the datagram to the receiver via the bus interface when: the MSB is equal to the receiver base address maintained in the shadow register, and the mask-and-data pair burst length is equal to the receiver masked-write burst length maintained in the shadow register.

Abstract: A method, an apparatus, and a computer program product for communication within a wireless terminal. The method can be implemented using dedicated logic and managed and controlled by state machines and/or sequencers. Data received or provided in a memory of a first integrated circuit of a terminal is encoded and transmitted in a data packet to a second integrated circuit. A header identifying the data type and providing a destination is included in the data packet. The destination may be identified as a memory address memory of the second integrated circuit that is mapped to a corresponding memory address of the first integrated circuit at which the data is received. In an aspect, the apparatus receives a header, detects an error in the received header, determines a failure to identify a packet boundary when the error is detected, and performs a search operation to identify the packet boundary.

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.
