DETAILED DESCRIPTION

[0018] FIG 1 depicts a simplified functional block diagram of a wireless communication system 100 consistent with some exemplary embodiments. The wireless communication system 100 may, in some exemplary embodiments, include user equipment 114 wirelessly coupled via wireless links 122 to a base station 110. The base station 110 may be coupled via a local link 124 to a display 180 configured to present video, such as for example high-definition video.

[0019] In some exemplary embodiments, the user equipment 114 may wirelessly transmit video, such as high-definition video, to the base station 1 10 via one or more wireless links 122, which may comprise cellular radio bearers. The base station 1 10 may receive the high- definition video and then provide output video via local link 124 to an input port at display 180, where the video is presented. System 100 may enable user equipment 114 to use another, and in some instances larger, or more capable, display 180, rather than a user interface at user equipment 114. For example, rather than use a 4 inch screen on a smart phone, the user may transmit video to base station 110, which is directly coupled to display 180, which may be a larger and/or a higher resolution display. Accordingly, high-definition videos, such as movies, clips, and the like, may be provided to the display 180 using, for example, one or more wireless links 122, such as standards- compliant cellular radio bearers between user equipment 114 and base station 110.

[0020] In some exemplary embodiments, the user equipment 114 may include one or more of the following: at least one processor, at least one non-transitory computer-readable storage medium (e.g., memory, storage, and the like), a radio interface, a user interface, and the like. The user equipment 114 may be implemented as, for example, a mobile device, a stationary device, a mobile station, a mobile unit, a subscriber station, a wireless terminal, a tablet, a wireless gaming device, a smart phone, a cellular phone, and the like.

[0021] In some exemplary embodiments, the user equipment 114 may communicate with base station 110 via wireless links 122 in accordance with one or more public land mobile network standards. Examples of public land mobile network standards include: the IEEE 802.16 series of standards (commercially known as WiMAX); GERAN (GSM/EDGE Radio Access Network); UTRAN (UMTS Terrestrial Radio Access Network); E-UTRAN (Evolved-UTRAN, which is also referred to as Long Term Evolution (LTE) and/or Long Term Evolution-Advanced (LTE-A)); and any other wireless technology/standard as well as any subsequent additions or revisions to those standards. For example, the wireless links 122 may comprise one or more cellular radio bearers, such as an uplink and a downlink, established between the user equipment 114 and the base station 110.

[0022] In some exemplary embodiments, the base station 110 may be implemented as a wireless base station, such as for example a Node B base station, an evolved Node B base station, a femtocell base station, and/or any other type of base station. In some exemplary embodiments, the base station 1 10 may be controlled by a network operator, in which case the frequencies (and/or the bandwidth allocations) being used by the base station 110 are controlled by, and in accordance with those used by, the network operator, such as a public land mobile network operator. However, the base station 110 may also use other frequency bands as well including frequency bands allocated to private users and unlicensed bands. Moreover, the base station 110 may change frequencies and adjust power to adapt to a licensed and/or unlicensed radio frequency environment. For example, the base station 110 may adapt, when communicating with user equipment 114, by selecting a low power, selecting a given frequency to avoid licensed and/or unlicensed users, and/or allocating a bandwidth for the video being transmitted from the user equipment 114 to the base station 110.

[0023] FIG. 2 depicts an example implementation of base station 110 in the dongle form factor, although other form factors may be implemented as well. The dongle form factor of base station 110 may enable base station 110 to be readily used with display 180. The base station 110 at FIG. 2 also includes an output port 210, which provides video (received at the base station from the user equipment 114) to an input port at display 180, where the video is presented.

[0024] In some exemplary embodiments, the dongle base station 110 depicted at FIG. 2 may be configured as a so-called "base station on a chip." Moreover, the dongle base station 110 depicted at FIG. 2 may be configured, in some exemplary embodiments, as a private base station serving only the display 180 and one or more devices, such as user equipment 114, seeking to present video, such as high-definition video, on display 180.

[0025] Referring again to FIG. 1 , the base station 110 may, in some exemplary embodiments, couple via one or more wireless links 122 to user equipment 114 and also couple via the local link 124 to display 180. As noted, wireless link 122 may be implemented as one or more cellular radio bearers or connections. The local link 124 may be implemented as a wired connection to the display 180, although a wireless link local 124 between the base station and the display (e.g., a Bluetooth link and the like) may be used as well. In any case, the local link 124 may couple a video output port of base station 110 to an input port at display 180 to enable presentation of the video, such as high-definition video. Examples of input ports at display 180 include High- Definition Multimedia Interface (HDMI), digital visual interface (DVI), component video, separate video (S-Video), and the like.

[0026] The display 180 may be implemented as any type of monitor or display capable of presenting video transmitted by the user equipment 114. For example, the display 180 may be implemented as a high-definition video monitor or a high-defmition television configured to present a video (including other information carried along with the video stream, such as for example audio, icons displayed at the user interface of user equipment 114, and the like). The phrase "video stream" refers to a channel of video being transmitted from the user equipment 114 to the base station 110. The video stream may be a so-called "real-time" video stream generated by a camera, such as a camera at user equipment 114, and/or generated as a video stream, such as a clip, a movie, etc., stored, either compressed or uncompressed, in memory 335. The video may also include so- called "static" content, such as icons, images, and the like presented at the user interface of user equipment 114 and then transmitted to the base station 110 for presentation at display 180. In some example embodiments, the display 180 may present video configured as high-definition video, such as video formatted as 480p, 720p, 720i, 1080p, and 1080i, although any other resolution or format may be presented by display 180 as well.

[0027] FIG. 3 depicts an example implementation of user equipment 114 consistent with some of the exemplary embodiments described herein. The user equipment 114 may include one or more of the following components: an antenna 320, a radio interface 370, a camera 380, a processor 330, a memory 335, a video compressor 340, a public subscriber identity module 345, a private subscriber identity module 350, and the like.

[0028] In some exemplary embodiments, the antenna 320 may include one or more antennas. Moreover, the antenna 320 may couple signals to, and/or from, radio interface 370. The radio interface 370 may include one or more components, such as for example filters, converters (e.g., digital-to-analog converters and the like), processors, symbol demappers, an Inverse Fast Fourier Transform (IFFT) module, a Fast Fourier Transform module, a precoder, a demodulator, a modulator, and the like.

[0029] In some exemplary embodiments, the user equipment 114 may further include at least one processor 330 for controlling the user equipment 114 and for accessing and executing program code stored in at least one memory 335 (which configures the user equipment and/or processor to perform the operations described herein). The processor 330 may also control the transmission of video and/or high-defmition video to display 180 via wireless links 122 as described herein.

[0030] In some exemplary embodiments, the processor 330 may include one or more of the following: one or more microprocessors; one or more processors with, or without,

accompanying digital signal processor(s); one or more special -purpose computer chips; one or more field-programmable gate arrays (FPGAS); one or more controllers; one or more application-specific integrated circuits (ASICS), and/or one or more computers. In some implementations, the user equipment 114 may also be compatible with one or more of the following: WiMAX, LTE, LTE- Advanced, and the like.

[0031] The memory 335 may, in some exemplary embodiments, include one or more of the following: read-only memory, random access memory, FLASH memory, and any other mechanism configured to store and/or retain information. For example, the memory 335 may be used to store compressed or uncompressed video for transmission to base station 110 and display 180. The memory 335 may also store other information, such as for example code/instructions to provide the operations disclosed herein.

[0032] The video compressor 340 may, in some exemplary embodiments, compress and/or decompress video, such as for example high-definition video. For example, user equipment 1 14 may store a video, such as a movie, a video stream, etc., at memory 335, and the video may, in some exemplary embodiments, be compressed by video compressor 340 before storage at memory 335. Similarly, when the video is read from memory 335, the video compressor 340 may also decompress the video before transmission, although the video may also be transmitted by user equipment 114 to base station 110 in a compressed format in which case the base station 110 would decompress the video. By compressing the video content, storage requirements may be reduced at memory 335.

[0033] Although video compression is described, in some exemplary embodiments, video compressor 340 may not be used. For example, when there is sufficient storage at memory 335, video compression 340 may not be used. Moreover, when camera 380 captures a video stream and immediately transmits the video steam in a so-called "real-time" format to base station 110, the video compressor 340 may be by-passed to enable transmitting uncompressed video to base station 110 for presentation at display 180.

[0034] In some exemplary embodiments, the public subscriber identity module 345 may be used to authenticate user equipment 1 14 to a network, such as an operator of a public land mobile network (e.g., authenticating with a authentication server in the operator's network). For example, the public subscriber identity module 345 may comprise a card, a module, and/or a circuit securely storing a secret key and the like to authenticate a user to the network.

[0035] In some exemplary embodiments, the private subscriber identity module 350 may be implemented as a real, physical subscriber identity module (SIM) card or a virtual subscriber identity module. A virtual subscriber identity module refers to information, such as a file, stored in memory, such as the memory 335. The virtual subscriber identity module may provide information similar to what a physical subscriber identity module card provides, but the virtual subscriber identity module is configured to only access the so-called "private" base station 110 in the dongle coupled to display 180.

[0036] The private subscriber identity card 350 may include a private, or secret, key used to authenticate user equipment 114 to base station 110. In this example implementation, the private subscriber identity module 350 may be used to authenticate, rather than use the public subscriber identity module 345 which is used to authenticate the user to an operator of a public land mobile network (e.g., authenticating with a authentication server in the operator's network). For example, the user of user equipment 114 may select base station 110 as a private network to which user equipment 114 authenticates using the secret key at private subscriber identity module 350. Although the previous example describes using a private subscriber identity module 350 and/or a virtual subscriber identity module to authenticate to base station 110 coupled to display 180, other authentication mechanisms may be used as well. For example, user equipment 114 may use the public subscriber identity module 345, use other authentication procedures including a simple password, and/or by pass authentication altogether.

[0037] FIG. 4 depicts an example of base station 110 consistent with some exemplary embodiments. The base station 110 may include one or more of the following: an antenna 420, a radio interface 440, a processor 430, a memory 435, an authenticator 460, a video compressor 475, and a display interface 445.

[0038] In some exemplary embodiments, the antenna 420 may include one or more antennas. The antenna 420 may couple signals to, and/or from, radio interface 440. The radio interface 440 may include one or more components, such as for example filters, converters (e.g., digital-to-analog converters and the like), processors, symbol demappers, an Inverse Fast Fourier Transform (IFFT) module, a Fast Fourier Transform module, a precoder, a demodulator, a modulator, and the like. [0039] As noted, the base station 110 may, in some exemplary embodiments, be implemented as a wireless base station, such as for example a Node B base station, an evolved Node B base station, a femtocell base station, and/or any other type of base station. Moreover, the base station 110 may also be compatible with one or more of the following: IEEE 802.16, LTE, LTE- Advanced, and the like. As noted above, the base station 100 may also be implemented as a dongle, a base station on a chip, and/or a private base station. Furthermore, base station 110 may, in some exemplary embodiments, be coupled to a public land mobile network, which may include access networks, a core network, an Internet, and/or an Internet Protocol Multimedia Subsystem (IMS).

[0040] In some exemplary embodiments, the base station 110 may further include at least one processor 430 for controlling the base station 110 and for accessing and executing program code stored in at least one memory 435 (which configures the base station and/or the processor to perform the operations described herein). Moreover, the processor 430 may also control base station 110, such that the video carried by the wireless links 122 is demodulated into a video stream and then output via display interface 445, which is coupled to an input at display 180.

[0041] The processor 430 may, in some exemplary embodiments, include one or more of the following: one or more microprocessors; one or more processors with, or without,

accompanying digital signal processor(s); one or more special-purpose computer chips; one or more field-programmable gate arrays (FPGAS); one or more controllers; one or more application-specific integrated circuits (ASICS), and/or one or more computers.

[0042] In some exemplary embodiments, the memory 435 may comprise one or more of the following: read-only memory, random access memory, FLASH memory, and any other mechanism configured to store and/or retain information (e.g., code, instructions, video, etc.) to provide the operations disclosed herein. The memory 435 may also buffer video streamed to display interface 445 and display 180. [0043] In some exemplary embodiments, the base station 110 may also include an authenticator 460 to authenticate the user equipment 114 accessing the base station 110 coupled to display 180. For example, the authenticator 460 may be able to authenticate (or initiate

authentication) of the user equipment 114. Although the authenticator 460 is depicted within base station 110, in some exemplary embodiments, the authenticator 460 is located in other devices. For example, the base station 110 may authenticate using the authentication mechanisms provided in a public land mobile network.

[0044] The base station 110 may, in some exemplary embodiments, also include a video de-compressor 475. For example, when the video is transmitted in a compressed format by user equipment 1 14, the video de-compressor 475 may decompress the video, such as high-definition video.

[0045] In some exemplary embodiments, the display interface 445 may directly couple the base station 110 to the display 180. Moreover, the display interface 445 may output a video (e.g., a high-definition video stream) formatted in accordance with an input port at display 180. For example, display interface 445 may output a high-definition video stream in one or more formats (e.g., HDMI, DVI, component video, S- Video, and the like) to an input port at display 180.

Furthermore, the display interface 445 may provide the video stream output in a wired and/or wireless (e.g., Bluetooth) form to an input port at display 180.

[0046] FIG. 5 depicts another example of a wireless communication system 500. The system 500 is similar in some respects to wireless communication system 100 described above.

However, the wireless communication system 500 depicts user equipment 514 and dongle form factor base station 550. The user equipment 514 is similar to user equipment 114 but further includes a user interface 510 and a video compressor 340. The dongle form factor base station 550 is similar to base station 110 but further includes a video decompressor 475. [0047] When a user decides to connect to dongle form factor base station 550 and display 180, a user at user equipment 514 may indicate that decision by, for example, selecting an icon 512 at user interface 510. The selection of icon 512 is received by a processor at user equipment 514, which may initiate a connection to the dongle form factor base station 550. Once the user equipment 514 is authenticated, user equipment 514 may connect to the base station 550 and transmit compressed video (which is compressed by video compressor 340). The compressed video is received at dongle form factor base station 550. The video de-compressor 475

decompresses the video. The decompressed video is then output by dongle form factor base station 550 to local link 124 and display 180, where the video is presented. In the example depicted at FIG. 5, the video 590 presented at display 180 comprises the contents of the user interface 510 of user equipment 514, but the video 590 presented at display 180 may include any other content, such as a high-definition movie, a clip, and the like.

[0048] FIG. 6 depicts an example of a process 600 which may be implemented, in some exemplary embodiments, at user equipment, such as user equipment 114 and/or 514. The description of process 600 also refers to FIGs. 1, 3, and 5.

[0049] In some exemplary embodiments, the user equipment (e.g., a processor in the user equipment) may receive, at 605, an indication that a user seeks to connect to the base station which is coupled to a display. For example, a user of user equipment 514 may select an icon 512 to initiate a connection to base station 550 in order to present high-definition video at display 180. This indication (e.g., a selection of the icon 512) may be received at processor 330.

[0050] The user equipment may, in some exemplary embodiments, authenticate, at 610, to the base station. The user equipment 514 may, for example, authenticate to the base station 550 using, for example, a secret key in at least one of the private subscriber identity module 350 and the public subscriber identity module 345. The user equipment 514 may also use a simple password and/or a virtual subscriber identity module to authenticate to base station 550. In some exemplary embodiments, the user equipment 514 and base station 550 exchange messages to authenticate one another by passing the authentication mechanisms provided by a network operator of a public land mobile network coupled to base station 550, although the network operator's authentication mechanisms may be used as well.

[0051] At 615, the user equipment 514 may, in some exemplary embodiments, generate a video for transmission from the user equipment to the base station coupled to the display. For example, the user equipment 514 may have a video to be displayed, but rather than display the video at the user equipment 514 (e.g., using the relatively small screen of a cell phone), the video is displayed on a larger, or more capable, display 180. In this example, the video may include high- definition video content with resolutions ranging from 480p to 1080p resolution. In some exemplary embodiments, the generated video may be stored in memory 335 after compression by video compressor 340. The compressed video may, in some exemplary embodiments, be read from memory 335 and then transmitted to base station 550, where the video de-compressor 475 decompresses the video. However, in some exemplary embodiments, the video compressor 340 may decompress the video stored in memory 335 before transmission to base station 550.

Furthermore, when real-time video is used, the video may not be compressed but instead transmitted directly to base station 550. In any case, the user equipment 514 may generate the video by forming a video stream.

[0052] In some exemplary embodiments, the user equipment may transmit, at 620, the video through one or more wireless links, such as cellular radio bearers to the base station to enable the base station to provide the video to a display for presentation. As noted above, the video at user equipment 514 may be transmitted to base station 550 via one or more links 122, such as standard cellular radio bearers established between the user equipment 514 and the base station 550. The base station 550 may thus be used to provide the user equipment's video to display 180 for presentation.

[0053] FIG. 7 depicts an example of a process 700 which may be implemented, in some exemplary embodiments, at a base station, such as base station 110 and/or 550. The description of process 700 also refers to FIGs. 1, 4, and 5.

[0054] In some exemplary embodiments, the base station may authenticate, at 710, the user equipment. The base station 550 may authenticate user equipment 514 in a manner compatible with the authentication process used at 610.

[0055] In some exemplary embodiments, the base station may receive, at 715, a video or video stream from links 122 (e.g., one or more radio bearers) and the user equipment. For example, the base station 550 may receive the video transmitted at 620 through one or more standard radio channels (e.g., radio bearers) established between the base station 550 and user equipment 514. The base station 550 may process the signal(s) carried by the radio channels, or bearers, and provide a video stream to display interface 445. The display interface 445 may process the video stream into one or more formats to enable presentation at display 180. For example, the display interface 445 may process the video stream into HDMI, DVI, component video, S-Video, and the like.

[0056] In some exemplary embodiments, the base station may provide, at 720, an output to the display to enable presentation of the video at the display. For example, the output of display interface 445 may be provided to an input of display 180. Moreover, the output of display interface 445 may be formatted in a manner compatible with the input at display 180. For example, the output of display interface 445 may provide the video stream in one or more of the following formats: HDMI, DVI, component video, S-Video, Bluetooth, and the like. Thus, the base station may be used as a way to route video from the user equipment (e.g., a cellular phone, a tablet, a smart phone, etc.) to a separate display 180, which may be better suited for video presentation than a user interface (and/or display) at the user equipment.
