A device implementing unified coordination of wireless communications over multiple physical layers may include a MAC module communicatively coupled to first and second physical layer modules that are each configured to communicate with another device over first and second physical wireless channels, respectively. The MAC module may be configured to provide data to the first physical layer module for transmission to the another device over the first physical wireless channel, where the first physical wireless channel is associated with a first link parameter. The MAC module may be further configured to facilitate initializing the second physical wireless channel based at least in part on the first link parameter of the first physical wireless channel, and after initialization of the second physical wireless channel, provide second data to the second physical layer module for transmission to the another device over the second physical wireless channel.

Unified coordination of multiple physical layer devices

A device implementing unified media access control (MAC) for multiple physical layer devices may include at least one processor communicatively coupled to first and second physical layer modules that are configured to communicate with another device over first and second wireless channels, respectively. The at least one processor may be configured to receive one or more data items to be transmitted to the another device and to select at least one of the first or second physical layer modules for transmission of the one or more data items based at least in part on a first condition of the first physical wireless channel and a condition of the second physical wireless channel. The at least one processor may be further configured to provide the one or more data items to the selected at least one of the first or second physical layer modules for transmission to the another device.

A multimode wireless communication device includes a first radio section operably to convert outbound analog baseband signals into first outbound RF signals and to convert first inbound RF signals into inbound analog baseband signals when the wireless communication device is in a first mode of operation and a second radio section that performs similar functions in a second mode of operation. A diplexer section includes a first diplexer for coupling to a first antenna, and a second diplexer for coupling to a second antenna, and that selectively couples the first radio section to one of the first antenna and the second antenna, and that selectively couples the second radio section to one of the first antenna and the second antenna. First and second T/R switches are coupled to the first and second diplexers and to respectively, to the first and second radio sections.

Multimode wireless communication device

A programmable transmitter generates a frame in a frame format according to one of a plurality of operating modes using a frame structure table storing a respective frame format for each of the operating modes. The transmitter includes a frame structure engine that receives a mode selection signal indicative of a select operating mode, and accesses the frame structure table to determine the frame format of the select operating mode. The frame structure engine produces a control signal to a frame generator to control the generation of a frame in the frame format of the select operating mode.

A multimode wireless communication device includes a first circuit having a digital baseband processing module to convert outbound data into outbound digital baseband signals and to convert inbound digital baseband signals into inbound data, an analog to digital converter module to convert inbound analog baseband signals into the inbound digital baseband signals, and a digital to analog converter module to convert the outbound digital baseband signals into outbound analog baseband signals. A second circuit includes a first radio section and a third circuit includes a second radio section. A diversity antenna arrangement includes a first antenna, a second antenna, a first diplexer coupled to the first antenna, and a second diplexer coupled to the second antenna, that selectively couples the first radio section to one of the first antenna and the second antenna, and that selectively couples the second radio section to one of the first antenna and the second antenna.

An integrated radio circuit includes a receiver section, a transmitter section, an analog to digital converter section, a digital to analog converter section, a digital baseband processing module, a first dual function input/output (I/O) module, and a second dual function I/O module. The first dual function input/output (I/O) module is operably coupled to provide inbound digital baseband signals as selected inbound digital baseband signals to the digital baseband processing module when the integrated radio circuit is in a normal mode of operation and to provide test inbound digital baseband signals as the selected inbound digital baseband signals to the digital baseband processing module when the integrated radio circuit is in a test mode. The second dual function I/O module is operably coupled to provide outbound digital baseband signals to the digital to analog converter section when the integrated radio circuit is in the normal mode of operation and to output the outbound digital baseband signals when the integrated radio circuit is in the test mode.

A digital-to-analog converter (DAC) disposed in a data transmission path to convert data from a digital format to an analog format to be transmitted is powered down during a receive mode of operation for a wireless communication device. Likewise, an analog-to-digital converter (ADC) disposed in a data reception path to convert received data from an analog format to a digital format is powered down during a transmit mode of operation.
