Abstract: Protocol adaptation layer for wireless communications. Communication devices that include one or more radio modules operable in accordance with multiple communication protocols establish communications using one communication protocol and then switch to another communication protocol. This switching to another communication protocol may be performed based on a variety of factors including effectuating communications of higher throughput, supporting uni-directional communications vs. bi-directional communications, or any other desired factor. In some embodiments, various communication devices include two radio modules that are each implemented to operate in accordance with one particular communication protocol. Alternatively, a multi-protocol capable radio module may support and operate in accordance with more than one communication protocol. Examples of possible communication protocols include those compliant with Bluetooth, IEEE 802.11, and/or 802.15.3c.

Abstract: Method and system encodes a signal according to a code rate that includes a ratio of uncoded bits to coded bits. An outer encoder encodes the signal into code words. An interleaver converts the code words into a byte sequence for wireless transmission. An inner encoder executes a convolutional code to generate an encoded signal. The encoded signal is transmitted over a plurality of subcarriers associated with a wide bandwidth channel having a spectral efficiency associated with the code rate. The outer encoder includes a Reed-Solomon encoder having a rate that increases the code rate of uncoded bits to coded bits.

Abstract: Aspects of the invention described herein may enable a greenfield access mode in IEEE 802.11n WLAN systems in comparison to an alternative approach that may not provide greenfield access. The utilization of greenfield access may reduce the portion of time required to transmit data due to overhead comprising preamble fields and header fields. This may enable higher data throughput rates to be achieved. This may further enable more robust transmission of data by enabling comparable data rates to be maintained while reducing the coding rate of encoded transmitted data. The reduction of the coding rate may enable comparable data rates to be maintained for transmission via RF channels characterized by lower SNR while still achieving desired target levels of packet error rates. In another aspect of the invention, mixed mode access may be achieved while reducing the portion of time required for transmitting data due to overhead.

Abstract translation: 与可能不提供绿地访问的替代方法相比，本文所述的本发明的方面可以实现IEEE 802.11n WLAN系统中的绿地接入模式。 绿地访问的利用可以减少由于包括前导字段和报头字段的开销而发送数据所需的时间部分。 这可以实现更高的数据吞吐率。 这可以通过在减少编码的发送数据的编码率的同时保持可比较的数据速率来进一步实现数据的更鲁棒的传输。 编码率的降低可以使得能够维持用于通过以较低SNR表征的RF信道的传输的可比数据速率，同时仍然实现期望的目标级别的分组错误率。 在本发明的另一方面，可以在减少由于开销而发送数据所需的时间的部分的同时实现混合模式访问。

Abstract: An integrated circuit radio transceiver and associated method comprises a multi-mode device operable to support personal area network communications as well as traditional wireless local area network communications. In one embodiment, IEEE 802.11 protocol IBSS communications are used to transport Bluetooth communication data packets. In another embodiment, a direct link comprising direct packet transfers without beaconing is performed between the multi-mode device and another multi-mode device. Thus, the multi-mode device is operable to establish traditional BSS communications with an Access Point in addition to establishing peer-to-peer communications with another multi-mode device to transport the Bluetooth communications over the 802.11 IBSS communication link or over an IEEE 802.11 direct communication link.
