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: In accordance with some embodiments of the present invention, a controller receives an indication of acceptance by a customer of an offer for a subsidy from a second vendor (e.g., a subsidizing vendor). The offer may define, for example, a reduction in the price charged for an item purchased from a first vendor and an obligation for the customer to fulfill in exchange for the subsidy. The customer is charged a second price for the items, which is less than the total price, and may even be zero.

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: 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: Exemplary embodiments are related to enhancing power efficiency of an electronic device. A device may include a power management module and a radio-frequency (RF) module coupled to the power management module. The device may further include a digital module coupled to each of the power management module and the RF module and configured to dynamically adjust at least one setting of the power management module based on one or more RF conditions.

Abstract: A method for reducing idle mode power consumption is disclosed. An idle mode is entered. A neighboring base station is selected. If the selected neighboring base station is assigned a high-frequency monitoring mode, a signal strength of the neighboring base station is measured. A low-frequency monitoring mode is assigned to the selected neighboring base station if the signal strength of the selected neighboring base station has been below a power threshold for longer than a time threshold. Other aspects, embodiments, and features are also claimed and described.

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: 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.

Abstract: In accordance with at least some embodiments, systems and methods provide for storing an indication of an initial purchase of a first new product from a supplier and by an initial purchaser and facilitating a provision to the initial purchaser of the second product by the supplier and a return of the pre-owned product from the initial purchaser to the supplier.
