A multi-chip antenna diversity architecture and method includes a first receiver chip that receives a first input signal from a first antenna. The first receiver chip includes a first tuner that amplifies the first input signal, a crystal operatively connected to a first crystal oscillator circuit, and a first crystal oscillator clock buffer that receives a clock signal from the first crystal oscillator circuit. A first demodulator demodulates the input signal received from the first tuner. A second receiver chip receives a second input signal from a second antenna. The second receiver chip includes a second crystal oscillator circuit, a second crystal oscillator clock buffer, a second tuner, and a second demodulator that receives diversity data from the first demodulator. The first crystal oscillator clock buffer drives the clock signal to the second crystal oscillator clock buffer, the second tuner, and the second demodulator of the second receiver chip.

A system and method includes a pair of voltage-controlled oscillators (VCOs) that include a first VCO generating a first signal associated with data transmission of a first type of wireless data signal; and a second VCO generating a second signal associated with data transmission of a second type of wireless data signal, wherein the first type of wireless data signal uses a different carrier frequency than the second type of wireless data signal. The system further includes a multiplexer operatively connected to the pair of VCOs that selectively outputs the first signal or the second signal to generate a selectively outputted signal; and a mixer operatively connected to the switch that combines the selectively outputted signal with at least one additional signal and outputs a composite signal. The first type of wireless data signal includes a WiFi signal. The second type of wireless data signal includes a Bluetooth signal.

A system and method of permitting coexistence of WiFi and Bluetooth data transfer on a single chip in UE including a transceiver includes using CTS data packets to protect Bluetooth signals for SCO communication links; using only WiFi circuitry in the chip to determine when Bluetooth data transfer is required by the UE; establishing a specified period of the Bluetooth data transfer; and starting WiFi medium contention only upon an end of the specified period of the Bluetooth data transfer on the single chip. The power save mode of the WiFi circuitry may be used with Bluetooth ACL data packets in WiFi periodic data transfer gaps. The WiFi data transfer has no timing constraints, whereas the Bluetooth data transfer has timing constraints and can only occur during the specified period. The WiFi data transfer does not occur when the Bluetooth data transfer is occurring.


A receiver arranged to process a flow of data in a communication system for downlink shared channels and a method for processing the flow of data sequence. The receiver includes a processor that receives a subframe comprising a data packet; a demapper that receives supplemental channel data symbols and is positioned after the processor in a sequence of the flow of data; means for performing rate matching of estimated the data symbols and positioned after the demapper in the data sequence; and a Hybrid Automatic Retransmission Request (HARQ) buffer positioned before the demapper in the data sequence. The communication system includes a long-term evolution (LTE) communication system.


Unbiased media contention in the presence of conflicting wireless operation of data transmission includes beginning media contention only during Bluetooth operation; treating the Bluetooth operation as a rejection of media transmission; holding a backoff timer associated with a backoff period steady for a specified duration; upon immediate completion of the Bluetooth operation, WiFi contends with a small backoff value when media access is busy; using a small random number for the backoff period during a non-Bluetooth data transfer period; and keeping an overall backoff timer unbiased for a duration of the data transmission. The specified duration may include an end of the Bluetooth operation or a maximum backoff time that is reached. The random number for the backoff period includes uniform distribution in a contention window. A mean backoff timer value equals a uniform mean value minus a ratio of a Bluetooth operation period to a total backoff period.

Memory management for WiFi Media Access Control (MAC) frames includes dividing a memory into equally-sized smaller chunks; writing a MAC frame that is larger in size than one-chunk size into several chunks; appending special information to each chunk to specify whether the chunk is a starting chunk or an intermediate chunk of the MAC frame or whether the chuck is currently unoccupied at all; linking the chunks carrying the MAC frame; and specifying a task waiting to be performed for the MAC frame. The several chunks may be noncontiguous or contiguous. The memory management technique may further comprise searching the memory for chunks comprising frames waiting for a certain task. The memory management technique may further comprise marking the chunks as empty after the certain task is completed.
