Abstract: A coexistence system including first and second transceiver modules and an arbitration module. The first transceiver module generates a first request signal and operates according to a first wireless communication standard. The first request signal requests transmission or reception for the first transceiver module. The second transceiver module generates a second request signal and an overlap signal and operates according to a second wireless communication standard. The second request signal requests permission for the second transceiver module to transmit or receive. The overlap signal indicates whether desensitization is expected of a frequency of the first transceiver module or a frequency of the second transceiver module. The arbitration module (i) based on the overlap signal, arbitrates the first and second request signals, and (ii) based on the arbitration of the first and second request signals, selectively connect antennas to the first and second transceiver modules in one multiple configurations.

Abstract: A network device including first, second and third transceiver modules, which transmit or receive first, second and third data signals. A control module generates a mask signal based on a parameter of the first, second or third transceiver modules. The mask signal includes a direction bit and a first channel that identifies a first frequency. The direction bit indicates a range of frequencies. Transmission on the first frequency and some of the range of frequencies causes desensitization of the second data signal. A hopping module, based on a clock signal, selects a second channel for the third data signal. An output module, based on the mask signal and the second channel, generates an overlap signal indicating whether potential desensitization of the first or third data signal exists. An arbitration module, based on the overlap signal, provides the first or third transceiver module access to a first or second switch module.

Abstract: A coexistence system including a first transceiver module and a second transceiver module. The first transceiver module generates an uplink indication signal and, subsequent to a first predetermined period after having transmitted the uplink indication signal, transmits first signals from a first network device to a second network device during an uplink period. The uplink indication signal indicates the first signals are to be transmitted subsequent to the first predetermined period. The first signals and the second signals respectively conform to first and second wireless communication standards. The second transceiver module, based on the uplink indication signal, transmits: the second signals during a portion of the uplink period unused by the first transceiver module; or a signal indicating a second predetermined period. The second predetermined period indicates to the second network device not to transmit the second signals to the second transceiver module during the second predetermined period.

Abstract: A first network device including first and second transceiver modules. The first transceiver module: during a first downlink period, transmits an uplink indication (UI) signal; and during an uplink period and subsequent to transmitting the UI signal, transmits a first data signal. The UI signal indicates when the first data signal is transmitted. The second transceiver module, prior to transmission of the UI signal, transmits a notice signal that indicates to a second network device not to transmit data to the second transceiver module during a second downlink period. The second downlink period is subsequent to an unused portion of the uplink period. The second transceiver module: transitions to a power save mode prior to transmission of the first data signal; and transmits a second data signal from the first network device based on the UI signal, subsequent to transmission of the first data signal, and during the unused portion.

Abstract: The present disclosure describes methods and apparatus for generating expanded code words to support error correction in a data communication system. In some aspects data to be encoded and a first subset of bits of a first bit sequence are obtained. A first combined bit sequence is generated by combining the data and the first subset of bits. A first code word is generated by applying an error correcting code to the first combined bit sequence. The first code word is combined with the first bit sequence, resulting in first encoded data that includes both first parity information and the data. The generating, applying, and combining are repeated with a second subset of bits of a second bit sequence, resulting in second encoded data that includes both second parity information and the data, the second encoded data being based on a second code word rather than the first code word.
