Problems solved by technology

With the various types of wireless communications (e.g., SISO, MISO, SIMO, and MIMO), and particularly within communication devices that may employ multiple communication paths therein, the present art does not provide an adequate solution by which various communications maybe performed and operated in a communication device without deleterious affecting one another.
Often times, such media related content communications are relatively more time critical than non-media related content communications.
Particularly in the context of wireless communications, the present art does not provide an adequate means by which media related content communications may be effectuated in a robust, reliable, and perceptually acceptable manner.

embodiment 300

[0048]FIG. 4 is a diagram illustrating an embodiment 300 of a wireless communication device that includes the host device 318-332 and an associated radio 460. For cellular telephone hosts, the radio 460 is a built-in component. For personal digital assistants hosts, laptop hosts, and / or personal computer hosts, the radio 460 may be built-in or an externally coupled component.

[0049]As illustrated, the host device 318-332 includes a processing module 450, memory 452, a radio interface 454, an input interface 458, and an output interface 456. The processing module 450 and memory 452 execute the corresponding instructions that are typically done by the host device. For example, for a cellular telephone host device, the processing module 450 performs the corresponding communication functions in accordance with a particular cellular telephone standard.

[0050]The radio interface 454 allows data to be received from and sent to the radio 460. For data received from the radio 460 (e.g., inboun...

embodiment 400

[0057]As one of average skill in the art will appreciate, the wireless communication device of the embodiment 400 of FIG. 4 may be implemented using one or more integrated circuits. For example, the host device may be implemented on one integrated circuit, the digital receiver processing module 464, the digital transmitter processing module 476 and memory 475 may be implemented on a second integrated circuit, and the remaining components of the radio 460, less the antenna 486, may be implemented on a third integrated circuit. As an alternate example, the radio 460 may be implemented on a single integrated circuit. As yet another example, the processing module 450 of the host device and the digital receiver and transmitter processing modules 464 and 476 may be a common processing device implemented on a single integrated circuit. Further, the memory 452 and memory 475 may be implemented on a single integrated circuit and / or on the same integrated circuit as the common processing modu...

embodiment 600

[0085]FIG. 6 is a diagram illustrating an embodiment 600 of a wireless communication device including multiple transceivers (or radios) therein. This diagram shows a wireless communication device 610 as being operative to support communications with various other wireless communication devices such as wireless communication devices 650, 660, and so on up to 670. In some embodiments, the wireless communication device 610 includes two radios 620 and 630. In some embodiments, the wireless communication device 610 includes more than two radios (e.g., respective radios 620 and so on up to 630 including at least one radio there between). Each respective radio includes a respective power amplifier (PA). For example, radio 620 includes a PA 620a, and radio 630 includes a PA 630a. In embodiments including more than two radios, radio 630 includes a PA 630a. Also, each of the respective radios may also include other components therein as well (e.g., 620b in radio 620, 630b in radio 630, etc.)....

Abstract

Synchronized calibration for wireless communication devices. A protocol is presented herein that allows for calibration operation(s) by one or more wireless communication devices to mitigate (or eliminate) the disruption caused to the communication medium thereby. A calibration announcement frame is provided by a wireless communication device intending to perform calibration operation(s), and respective receiving wireless communication devices may adaptively determine whether to perform a calibration operation based thereon. In response to a calibration announcement frame, one or more other wireless communication devices may also perform calibration operation(s) (e.g., in accordance with a group calibration event, simultaneously, etc.) or may perform some operations as to minimize any effects that may be incurred during such a calibration operation(s) (e.g., enter into some robust operational mode, power savings mode, etc.). Such a calibration announcement frame may indicate respective time slots (e.g., maintenance window) during which respective wireless communication devices may perform calibration operation(s).
