Such mobile devices 104 can include various data inputs to enable device-specific features and/or any other suitable data transmission associated with the base stations 102, the mobile device 104, a disparate mobile device 104, etc. In particular, the mobile device 104 can include a motion input that can employ four or more degrees of freedom for data entry and/or motion entry. Generally, the motion input can be incorporated into any suitable mobile device 104 such as, but not limited to, a cellular phone, a smartphone, portable device, a text messenger, a hand-held device, a mini-computer, a portable digital assistant (PDA), a hand-held computing device, a satellite radio, a satellite device, a global positioning system (GPS), a GPS device, and/or any other suitable device that can receive data via an input.
Specifically, the motion input can be integrated into at least one side on the mobile device 104, wherein the mobile device 104 can have a front, a back, and at least two sides associated therewith. In one example, the motion input can be substantially similar to at least one of a mouse input device, a trackball, a roller-ball, and/or a touchpad. For instance, a mobile communication device can employ a trackball embedded on at least one side. The user can grasp the mobile communication device in a hand, wherein at least one digit can utilize the embedded trackball (e.g., motion input) to enter data with four or more degrees of freedom. Thus, a left-handed user can maneuver a cursor on a mobile device display utilizing the motion input on the left side of the mobile device 104 with their left thumb.
Conventionally, such mobile devices 104 and/or hand-held devices are limited in providing degrees of freedom for data entry. Implementing an external mouse and/or trackball device to the mobile device limits the use of such device and, even more so, defeats the purpose of providing mobility and ease of use. Moreover, typical inputs for mobile devices 104 and/or portable devices are limited to directional inputs such as up, down, left, and right. Thus, the motion input provide superior functionality with allowing data entry in N degrees of freedom, where N is a positive integer. In other words, the data entry utilizing the incorporated motion input can allow analog-like data entry and/or control for the mobile device 104 and/or portable device.

On at least one side of the casing, a motion input 206 can be embedded and/or incorporated into the portable device 200. It is to be appreciated that the motion input 206 can be a trackball, a roller-ball, a touchpad, a motion-detection device, and/or any other suitable device that can detect and/or collect data associated with motion. The motion input 206 can be at least partially protruding from an aperture on the side of the portable device 200. As depicted, the motion input 206 can be a spherical object, wherein at least a portion of such spherical object is protruding from the side to allow contact with a digit associated with a user for motion detection. However, it is also to be appreciated that the motion input 206 can be a touchpad (e.g., discussed infra).
The motion input 206 can be positioned on the portable device 200 such that upon the grasping and/or holding of such device, the motion input 206 can detect and/or collect data associated with at least one digit (e.g., thumb, finger, etc.). A user can hold the portable device 200 with the back portion on the palm of a hand with four fingers on one side and the thumb on the other side. Thus, the positioning of the motion input 206 can correlate with any of these digits on either side of the device (e.g., an additional or optional motion input is shown at 208). Although such configuration and/or placement of the motion input 206 can vary based on user-preferences, the thumb is an extremely versatile digit and placement of the motion input 206 can coincide therewith. Moreover, based on whether the device is for a left-handed user and/or a right-handed user, the motion input can be placed on the respective side (e.g., for a left-handed user, the motion input 206 will be on the left side while for a right-handed user, the motion input 206 will be on the right side). In addition, the portable device 200 can include more than one motion input 206 for ambidextrous users and/or to allow the portable device 200 to be utilized by either user (e.g., left-handed and/or right-handed). In other words, the portable device 200 can include a plurality of motion inputs 206, wherein each motion input 206 can have a respective functionality associated therewith. Moreover, the motion input 206 can also be used (in addition to navigating data) to provide input such as clicks that indicate user selection, transfer of control, or any other suitable action utilizing a motion input 206. For instance, a user can depress the motion input 206 (e.g., ball/button, trackball, a roller-ball, a touchpad, a motion-detection device, and/or any other suitable device that can detect and/or collect data associated with motion, etc.) that may activate a switch to indicate the click.
For example, the portable device can be a cellular phone that includes a camera, calendar, address book, Internet browser, media player, audio recorder, etc. By incorporating the motion input 206 into the cellular phone, data selection, navigation, and/or device functionality is greatly enhanced and optimized. The motion input 206 can provide N degrees of freedom for motion input, where N is a positive integer. For example, the cellular phone may include a cursor that can be navigated in a diagonal direction with the motion input 206 which cannot be implemented with conventional data inputs on portable devices. Moreover, the motion input 206 can provide analog-like input to navigate data related to the cellular phone, which bodes extremely well for navigating data (e.g., utilizing a cursor, etc.) with a device providing numerous functions. Thus, a user can easily select a particular application and/or function (e.g., camera, calendar, address book, Internet browser, media player, audio recorder, etc.) and/or activate such data related thereto, and so on and so forth.
In another example, the motion input 206 can also provide a key input functionality, wherein the motion input 206 can be depressed into the side of the portable device 200 (e.g., substantially similar to a button input). In the example with the motion input 206 being a roller-ball and/or trackball, the spherical object can be depressed inwards toward the side of the portable device 200 to replicate a button being depressed. Thus, the motion input 206 can navigate and/or select data associated with the portable device 200. In the example with the motion input 206 being a touchpad, the touchpad can detect a tap and/or quick touching that replicates a clicking on a mouse. Such detection of tapping and/or quick touching can be utilized to select data as well.
As still another example, the motion input 206 can be activated and/or de-activated to reduce the chances of accidental contact and/or data entry/navigation. For instance, any activation and/or de-activation technique can be utilized such as a button, a key, a voice command, a switch, a password, a fingerprint, a double-click, a sequence of inputs (e.g., particular motions on the motion input), retinal scan, etc. In other words, based on the motion input allowing data entry and/or navigation for the portable device, it is to be appreciated that any suitable technique and/or mechanism can be employed to reduce accidental contact and ensure data collection from the motion input is intentional.

It is to be appreciated that the touchpad motion input 302 can be on any location on the side of the portable device 300 that corresponds to a digit (e.g., finger, thumb, etc.). Such configuration and/or placement of the touchpad motion input 302 can vary based on user-preferences, yet the thumb is an extremely versatile digit and placement of the touchpad motion input 302 can coincide therewith. Furthermore, the touchpad motion input 300 can be sunk into the side to signify its presence, raised from the side to signify its presence, and/or flush with the side to blend into the side of the portable device 300. Although the touchpad motion input 302 is illustrated as a rectangle, it is to be appreciated that any suitable size and/or shape can be utilized to implement the touchpad motion input 302.

For example, the memory 402 can include instructions on collecting data from the motion input and/or touchpad motion input, wherein such instructions can be executed by the processor 404 to allow for data navigation associated with the portable apparatus 400. The data navigation can be implemented such that an analog-like input can be provided by the motion input to allow N degrees of freedom, where N is a positive integer. Moreover, the motion input can be utilized to activate and/or employ particular functions and/or features associated with the portable apparatus 400.
In another example, the instructions within the memory 402 can relate to coordinating motion input data collected with navigation within a display on the portable apparatus 400. Thus, a particular movement (e.g., motion input data) can be detected, collected, and utilized from the motion input to correlate with data displayed on the portable apparatus 400. For instance, a movement in the Y direction with the motion input can correlate to a movement in the Y direction on the display. In still another example, the memory 402 can store instructions associated with settings, user profiles, configurations, scaling features (e.g., an amount of movement for the motion input translates to particular amount of movement on the display, etc.), etc., wherein the processor 404 can retrieve and execute such instructions to allow the implementation of analog-like navigation with the motion input.

TMTR 920 receives and converts the stream of symbols into one or more analog signals and further conditions (e.g., amplifies, filters, and frequency upconverts) the analog signals to generate a downlink signal suitable for transmission over the wireless channel. The downlink signal is then transmitted through an antenna 925 to the terminals. At terminal 930, an antenna 935 receives the downlink signal and provides a received signal to a receiver unit (RCVR) 940. Receiver unit 940 conditions (e.g., filters, amplifies, and frequency downconverts) the received signal and digitizes the conditioned signal to obtain samples. A symbol demodulator 945 demodulates and provides received pilot symbols to a processor 950 for channel estimation. Symbol demodulator 945 further receives a frequency response estimate for the downlink from processor 950, performs data demodulation on the received data symbols to obtain data symbol estimates (which are estimates of the transmitted data symbols), and provides the data symbol estimates to an RX data processor 955, which demodulates (i.e., symbol demaps), deinterleaves, and decodes the data symbol estimates to recover the transmitted traffic data. The processing by symbol demodulator 945 and RX data processor 955 is complementary to the processing by symbol modulator 915 and TX data processor 910, respectively, at access point 905.
On the uplink, a TX data processor 960 processes traffic data and provides data symbols. A symbol modulator 965 receives and multiplexes the data symbols with pilot symbols, performs modulation, and provides a stream of symbols. A transmitter unit 970 then receives and processes the stream of symbols to generate an uplink signal, which is transmitted by the antenna 935 to the access point 905.
At access point 905, the uplink signal from terminal 930 is received by the antenna 925 and processed by a receiver unit 975 to obtain samples. A symbol demodulator 980 then processes the samples and provides received pilot symbols and data symbol estimates for the uplink. An RX data processor 985 processes the data symbol estimates to recover the traffic data transmitted by terminal 930. A processor 990 performs channel estimation for each active terminal transmitting on the uplink. Multiple terminals may transmit pilot concurrently on the uplink on their respective assigned sets of pilot subbands, where the pilot subband sets may be interlaced.
Processor 990 and 950 direct (e.g., control, coordinates, manage, etc.) operation at access point 905 and terminal 930, respectively. Respective processors 990 and 950 can be associated with memory units (not shown) that store program codes and data. Processors 990 and 950 can also perform computations to derive frequency and impulse response estimates for the uplink and downlink, respectively.
For a multiple-access system (e.g., FDMA, OFDMA, CDMA, TDMA, etc.), multiple terminals can transmit concurrently on the uplink. For such a system, the pilot subbands may be shared among different terminals. The channel estimation techniques may be used in cases where the pilot subbands for each terminal span the entire operating band (possibly except for the band edges). Such a pilot subband structure would be desirable to obtain frequency diversity for each terminal. The techniques described herein may be implemented by various means. For example, these techniques may be implemented in hardware, software, or a combination thereof. For a hardware implementation, the processing units used for channel estimation may be implemented within one or more application specific integrated circuits (ASICs), digital signal processors (DPSs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, other electronic units designed to perform the functions described herein, or a combination thereof. With software, implementation can be through modules (e.g., procedures, functions, and so on) that perform the functions described herein. The software codes may be stored in memory unit and executed by the processors 990 and 950.
