Abstract:
Music can be broadcast from a radio station and recorded onto a cache of a personal electronic device, such as a portable digital music player. The recording can occur such that there is segmenting of music into different cache portions based upon classification. Instead of playing music from the radio station, music can be played from the cache to ensure high quality and desirable variety. Different rules can be used to govern which music is played as well as how music should be removed from the cache. In addition, targeted advertisements can be used that relate to the music in the cache as well as a user location.

Description:
BACKGROUND 
       [0001]    1. Field 
         [0002]    The following description relates generally to wireless communications and, more particularly, to managing multiple multimedia services, commonly in conjunction with a mobile device. 
         [0003]    2. Background 
         [0004]    Wireless communication systems are widely deployed to provide various types of communication content such as, for example, voice, data, and so on. Typical wireless communication systems can be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, . . . ). Examples of such multiple-access systems can include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, and the like. 
         [0005]    Generally, wireless multiple-access communication systems can simultaneously support communication for multiple mobile devices. Each mobile device can communicate with one or more base stations via transmissions on forward and reverse links. The forward link (or downlink) refers to the communication link from base stations to mobile devices, and the reverse link (or uplink) refers to the communication link from mobile devices to base stations. Further, communications between mobile devices and base stations can be established via single-input single-output (SISO) systems, multiple-input single-output (MISO) systems, multiple-input multiple-output (MIMO) systems, and so forth. 
         [0006]    MIMO systems commonly employ multiple (NT) transmit antennas and multiple (NR) receive antennas for data transmission. A MIMO channel formed by the NT transmit and NR receive antennas can be decomposed into NS independent channels, which can be referred to as spatial channels. Each of the NS independent channels corresponds to a dimension. Moreover, MIMO systems can provide improved performance (e.g., increased spectral efficiency, higher throughput and/or greater reliability) if the additional dimensionalities created by the multiple transmit and received antennas are utilized. 
         [0007]    MIMO systems can support various duplexing techniques to divide forward and reverse link communications over a common physical medium. For instance, frequency division duplex (FDD) systems can utilize disparate frequency regions for forward and reverse link communications. Further, in time division duplex (TDD) systems, forward and reverse link communications can employ a common frequency region. FDD and TDD can be implemented upon a MIMO system through a WWAN (Wireless Wide Area Network). However, conventional techniques can provide limited or no feedback related to channel information.

     DETAILED DESCRIPTION 
       [0040]    Various aspects are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It can be evident, however, that such aspect(s) can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments. 
         [0041]    As used in this application, the terms “component,” “module,” “system” and the like are intended to include a computer-related entity, such as but not limited to hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a computing device and the computing device can be a component. One or more components can reside within a process and/or thread of execution and a component can be localized on one computer and/or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. The components can communicate by way of local and/or remote processes such as in accordance with a signal having one or more data packets, such as data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems by way of the signal. 
         [0042]    Furthermore, various aspects are described herein in connection with a terminal, which can be a wired terminal or a wireless terminal. A terminal can also be called a system, device, subscriber unit, subscriber station, mobile station, mobile, mobile device, remote station, remote terminal, access terminal, user terminal, terminal, communication device, user agent, user device, or user equipment (UE). A wireless terminal can be a cellular telephone, a satellite phone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device having wireless connection capability, a computing device, portable (or personal) media player (PMP), or other processing devices connected to a wireless modem. Moreover, various aspects are described herein in connection with a base station. A base station can be utilized for communicating with wireless terminal(s) and can also be referred to as an access point, a Node B, or some other terminology. 
         [0043]    Moreover, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from the context, the phrase “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, the phrase “X employs A or B” is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from the context to be directed to a singular form. 
         [0044]    Moreover, various aspects or features described herein can be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques. The term “article of manufacture” as used herein is intended to encompass a computer program accessible from any computer-readable device, carrier, or media. For example, computer-readable media can include but are not limited to magnetic storage devices (e.g., hard disk, floppy disk, magnetic strips, etc.), optical disks (e.g., compact disk (CD), digital versatile disk (DVD), etc.), smart cards, and flash memory devices (e.g., EPROM, card, stick, key drive, etc.). Additionally, various storage media described herein can represent one or more devices and/or other machine-readable media for storing information. The term “machine-readable medium” can include, without being limited to, wireless channels and various other media capable of storing, containing, and/or carrying instruction(s) and/or data. 
         [0045]    The techniques described herein can be used for various wireless communication systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other systems. The terms “system” and “network” are often used interchangeably. A CDMA system can implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband-CDMA (W-CDMA) and other variants of CDMA. Further, cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA system can implement a radio technology such as Global System for Mobile Communications (GSM). An OFDMA system can implement a radio technology such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM□, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunication System (UMTS). 3GPP Long Term Evolution (LTE) is a release of UMTS that uses E-UTRA, which employs OFDMA on the downlink and SC-FDMA on the uplink. UTRA, E-UTRA, UMTS, LTE and GSM are described in documents from an organization named “3rd Generation Partnership Project” (3GPP). Additionally, cdma2000 and UMB are described in documents from an organization named “3rd Generation Partnership Project 2” (3GPP2). Further, such wireless communication systems can additionally include peer-to-peer (e.g., mobile-to-mobile) ad hoc network systems often using unpaired unlicensed spectrums, 802.xx wireless LAN, BLUETOOTH and any other short- or long-range, wireless communication techniques. Additionally, aspects can be practiced in relation to MediaFLO, DVB-H (Digital Video Broadcasting-Handheld), ISDB-T (Integrated Services Digital Broadcasting-Terrestrial), and the like. 
         [0046]    Various aspects or features will be presented in terms of systems that can include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems can include additional devices, components, modules, etc. and/or can not include all of the devices, components, modules etc. discussed in connection with the figures. A combination of these approaches can also be used. 
         [0047]    Referring now to  FIG. 1 , a wireless communication system  100  is illustrated in accordance with various embodiments presented herein. In some aspects, a communication network  102  comprises a wireless access network  104  operable to enable wireless communications and a media distribution network  106  operable to distribute a plurality of content  134  to a plurality of wireless devices, including wireless devices  122  and  128 . System  100  comprises a base station  108  that can include multiple antenna groups. For example, one antenna group can include antennas  110  and  112 , another group can comprise antennas  114  and  116 , and an additional group can include antennas  118  and  120 . Two antennas are illustrated for each antenna group; however, more or fewer antennas can be utilized for each group. Base station  108  can additionally include a transmitter chain and a receiver chain, each of which can in turn comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art. 
         [0048]    Base station  108  can communicate with one or more mobile devices such as mobile device  122  and mobile device  128 ; however, it is to be appreciated that base station  108  can communicate with substantially any number of mobile devices similar to mobile devices  122  and  128 . Mobile devices  122  and  128  can be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable device for communicating over wireless communication system  100 . As depicted, mobile device  122  is in communication with antennas  118  and  120 , where antennas  118  and  120  transmit information to mobile device  122  over a forward link  124  and receive information from mobile device  122  over a reverse link  126 . Moreover, mobile device  128  is in communication with antennas  110  and  112 , where antennas  110  and  112  transmit information to mobile device  128  over a forward link  130  and receive information from mobile device  128  over a reverse link  132 . In a frequency division duplex (FDD) system, forward link  124  can utilize a different frequency band than that used by reverse link  126 , and forward link  130  can employ a different frequency band than that employed by reverse link  132 , for example. Further, in a time division duplex (TDD) system, forward link  124  and reverse link  126  can utilize a common frequency band and forward link  130  and reverse link  132  can utilize a common frequency band. 
         [0049]    The set of antennas and/or the area in which they are designated to communicate can be referred to as a sector of base station  108 . For example, multiple antennas can be designed to communicate to mobile devices in a sector of the areas covered by base station  108 . In communication over forward links  124  and  130 , the transmitting antennas of base station  108  can utilize beamforming to improve signal-to-noise ratio of forward links  124  and  130  for mobile devices  122  and  128 . Also, while base station  108  utilizes beamforming to transmit to mobile devices  122  and  128  scattered randomly through an associated coverage, mobile devices in neighboring cells can be subject to less interference as compared to a base station transmitting through a single antenna to all its mobile devices. 
         [0050]    Further, communication network  102  comprises one or more content providers  136 ,  138  operable to provide all or some portion of the plurality of content  134  for distribution to users in network  102 . For example, the plurality of content  134  supplied by content providers  136 ,  138  may comprise at least one of video, audio, multimedia content, real-time content, non real-time content also referred to as “clips,” scripts, programs, data or any other type of suitable content. The plurality of content  24  may include one or any combination of subscribed to programming, ad hoc and/or on-demand programming, advertising or any other form of content presented during a break within and/or simultaneously with other content. In some aspects, content providers  136 , 138  communicate with the media distribution system  106  via a communication link  140 , which may comprise any suitable type of wired and/or wireless communication interface. 
         [0051]    In some aspects, media distribution network  106  may comprise a transport system that operates to create and transport a multimedia content flow  142 , including one or more media services  144 , across one or more data network  146 . For example, such a transport system may include a multicast mechanism  148 . In some aspects of multicasting, each flow  142  is a logical stream within a “multiplex,” which is a set of flows available in a given geographical area. For example, multicast mechanism  148  may comprise all or some portion of a multicast system such as a Forward Link Only (FLO) network, including the MEDIAFLO™ System available from Qualcomm, Inc. of San Diego, Calif. It is to be appreciated that MediaFLO is one example of a broadcast network, and that other examples may include DVB-H (Digital Video Broadcasting-Handheld) and T-DMB (Terrestrial-Digital Multimedia Broadcasting) systems. Further, media service  144  comprises one or some combination of the plurality of content  134 , where a media service customized for a specific retailer may be referred to as a “channel.” As such, each flow  142  is able to deliver the same service  144  to a plurality of endpoints at the same time, as the flow is available to any device tuning in to the proper frequency, thereby avoiding scalability issues. Therefore, media distribution network  106  may be operable to transport media content in a one-to-many fashion. 
         [0052]    Now referring to  FIG. 2 , an example system  200  is disclosed for managing retention of information (e.g., multimedia content such as music, videos, Internet broadcasts, etc.). A media application  202  can be used to stream content from a source to a content device (e.g., the mobile device  122  or  128  of  FIG. 1 ). The media application  202  can function such that multiple streams of information can be transmitted to the content device at a single time. 
         [0053]    A buffer  204  can be used as a temporary storage location for streamed information collected by the media application  202 . Various modules can operate upon the information retained in the buffer  204 . For instance, there can be analysis of the information to determine characteristics, perform a classification, etc. In addition, the buffer  204  can be used to temporarily retain information until a determination can be made on other portions of the system  200  (e.g., determine if there is room in a cache  206  for the information to be stored). 
         [0054]    A cache  206  can be used to retain information obtained through use of the media application  202 . According to one embodiment, the cache  206  can operate as a sectored cache such that the cache  206  is divided (e.g., physically, logically, etc.) into different portions. For example, the media application  202  can obtain streamed music from a radio station. The buffer  204  can temporarily retain the music while a classification of the music is determined (e.g., jazz, pop, etc.). Based upon the classification, different cache portions can be used for retention of information types (e.g., a grouping of songs in a particular genre). For instance, there can be a cache portion  208  for jazz music, a cache portion  210  for rock music, and a cache portion  212  for country music. It is to be appreciated that one song can be retained in multiple cache portions (e.g., a song that includes rock music and country music elements can be retained in portions  210  and  212 ). In one implementation, a song is physically retained in one portion but logically retained in multiple portions (e.g., can be accessed 
         [0055]    The size of the cache portions  208 ,  210 , and  212  can be designated by a user as well as adaptively changed automatically based upon how often the user listens to a particular music type (e.g., ongoing modification based upon user habits). In addition, a user can request that a new cache portion be created and/or a cache portion be removed. For instance, the user can request the cache portion  210  for rock music be divided into two new portions—one portion for hard rock and one portion for soft rock. The cache  206  can automatically be modified such that the change is implemented. While being disclosed as user initiated, it is to be appreciated that the cache  206  can self-modify, the cache  206  can be modified through use of a third-party entity, etc. In addition, the cache  206  and/or cache portions can operate on a first-in-first-out basis. 
         [0056]    A user interface  214  can operate in conjunction with an overall user experience so music is played from the cache  206 . The user experience can allow a user to select a channel that corresponds to a cache portion and thus allow different functionality (e.g., stop, repeat, skip, etc.). The user interface  214  can disguise playing from the cache  206  as originating from a radio station. According to one implementation, live, streaming content is saved to the cache  206  and the content being output from a device implementing the system  200  “lags” the received streaming content. This “lag” allows the device to maintain quality, etc., such as based on temporarily losing signal there would not be an impact upon a user&#39;s perception of the live stream. 
         [0057]    With one embodiment, a user can listen exclusively to content on the cache  206  and could be unaware that she is not listening to live content. For instance, the media application  202  can present to the user a large number of virtual radio stations (e.g., through the user interface  214 ). The device could capture the songs from a live music broadcast service or from a tailored and dedicated broadcast service for this embodiment. A particular song can be assigned to specific radio stations based on meta-data associated with the song (e.g., based on genre) and played for the user while the user designates an appropriate station. The device could continue to capture new content being broadcasted to supply and maintain the cache  206  with fresh content to minimize exposure of the user to the same song too many times, e.g., a song to which the user has had multiple exposure can be replaced with a new song being broadcasted. The replacement policy can consider many variables when trying to minimize excessive exposure to the same song, e.g., battery life, battery status, number of songs assigned to each station, current exposure status of songs, users listening habits, etc. A media application radio station can attempt to mirror a live radio station—however, suitable modifications can be made. Advertisements can be integrated with the media application radio station under similar constraints of songs—for instance, that advertisements are related to a genre (e.g., a country music concert advertisement is likely more relevant on a country music station than an advertisement for a new jazz album) and a user is not highly exposed to the advertisement. If connectivity is lost with the broadcast service, then the media application  202  can continue operation without the user becoming aware of the loss. The system  200  can be implemented such that there is no mirror of a live station and the media application  202  presents functional stations to a user through use of the cache  206 . This can facilitate that the number of virtual radio stations can be much larger than the number of radio stations a live broadcast service with the same bandwidth could support. 
         [0058]    While commonly there is use of broadcasts (e.g., concerning MediaFLO™), it is to be appreciated that aspects disclosed herein can be practiced through a unicast and/or multicast experience on a broadcast network. With unicast, there can be sending of information packets to a single destination. While such transmissions can be picked up by multiple receivers, commonly only an addressed receiver will digest the data. Physically, messages can be directed over those links (e.g., only over those links) in a network (e.g., a network required to achieve delivery)—thereby limiting the number of devices on the network that actually receive the messages to a minimum. Unicast allows a user to request personalized data on the fly—at a time designated by a user, the user can select content which is then transmitted to him. 
         [0059]    Regarding multicast, there can be transmitting information packets addressed to a range of receivers. Multicast can typically implement on an otherwise unicast based network using network addressing methods for the delivery of information to a group of destinations simultaneously. Multicast methods generally strive for efficiency through delivering the messages over each link of the network only once, creating copies only when the links to the multiple destinations split (e.g., typically at network switches and routers). Multicast can be used for streaming media and Internet television applications where the media is streamed to all requesting users in the same time frame (e.g., a user is watching the same stream at the same time as the other requesters). 
         [0060]    For a broadcast, there can be transmitting information (e.g., packetized, non-packetized) to units capable of receiving the transmission (e.g., all units without distinction). Broadcast network are usually physically separate from unicast based networks as generally, broadcast transmissions of user data is not efficient on a unicast based network. Broadcast networks are also generally thought of as being one way communication paths. For example, the MediaFLO™ system can be described as “forward link only” referring to the one-way flow of data. It is to be noted that most digital video broadcasting networks, such as MediaFLO™, use digital rights management systems to prevent the decoding of the received data absent subscriptions. In some ways this mimics functionality of multicast systems in that only those users electing (e.g., paying) to receive the content can view the content. 
         [0061]    Referring to  FIG. 3 , an example system  300  is disclosed for using a cache  206  to manage information, such as multimedia content. A content device  302  (e.g., a mobile device  122  or  128  of  FIG. 1 , cellular telephone, personal digital assistant, music player, etc.) can interact with a provider  304  to collect content. In a conventional configuration, a user can employ a radio to listen to music where the music is broadcast over public airwaves. In addition, a user can download music from a music store and retain the music upon a personal device. 
         [0062]    In accordance with aspects disclosed herein, there can be a merger of aspects related to radio play and/or music store with local media usage (e.g., songs stored on a local cache). With one embodiment, a user can attempt to play music from the radio station—however, as opposed to playing music from the radio station (e.g., directly broadcast from the radio station), music can be played from the cache  206 . The cache  206  can automatically select a song—selection of a song can be based upon if the song is new or already played, time last played, users explicit feedback for the same song, relation to songs played by a same artist, user implicit feedback (e.g. skipping a song or playing it again), quality, randomization so play does not seem as a endless loop, etc. 
         [0063]    Playing music from the cache  206  can enable greater user functionality (e.g., pause music, repeat, etc.), protect from losses in signal coverage from the radio, and the like. In one example, music played from the cache  206  mirrors what is played by the radio; when a signal to the radio is lost, the music continues to play (e.g., notifying the user of the interruption, not notifying the user, and the like). If a song is playing on the live stream that is in the cache, when the live stream is lost the song can be identified in the cache and the song continued. Allowing a user to listen to music from the live source can enable the user to appreciate potential new content and determine if music should be retained. As a song plays from the live stream, it can be retained in the buffer  204  of  FIG. 2  (as well as after play for a time) so a user can determine if the content should be retained in the cache  206 . 
         [0064]    The content device  302  can retain information upon the cache  206  supplied from the cache  206 . While the cache  206  is disclosed as being separate from the content device  302  (e.g., as a removable flash memory device), it is to be appreciated that the cache  206  can integrate as part of the content device  302 . The content device  302  can use a recognizer  306  that identifies multimedia content, such as music. For example, as information enters the content device (e.g., from a radio station, through download from a music store), an identification can occur on the information—identification that information is music, that the content is multimedia information that is authorized for storage, and the like. Identification can occur through analyzing the information as well as metadata associated with the information and making a determination on identity. Other identifications can occur, such as information not being multimedia content, information being unknown, etc. Once identified, a maintainer  308  can retain at least a portion of the identified multimedia content (e.g., content identified as music) automatically in the cache  206  in a format used by the cache  206  (e.g., performing modification of the content from a transmitted form to a retainable form if appropriate). 
         [0065]    The provider  304  can supply multimedia content to the content device  302 . A classifier  310  can be used that identifies a broadcast load (e.g., an amount of space available to transmit content). Based upon the identification, a resolver  312  can determine an amount of multimedia content to provide based upon the identified load. For example, the provider  304  can produce multiple songs in one transmission or produce more detailed songs of higher quality (e.g., songs subjected to a higher sampling rate). It is to be appreciated that aspects disclosed herein can be practiced through playing content for the cache  206 —playing content for the cache  206  cancan enable more content than can fit on a live channel, can have higher likelihood of availability (e.g., no concern for signal quality), have higher guarantee of quality, and the like. 
         [0066]    Referring to  FIG. 4 , an example system  400  is shown for placement of multimedia content upon a cache  206  for use of a content device  302 . The placement can be organic such that it follows general desires of a user, commonly based upon past history. An examiner  402  can be employed that observes usage related to multimedia content. Based upon the observation, a separator  404  can determine how to divide the cache  206  (e.g., by classifications, sizes, etc.) and then divide the cache  206  into at least two classifications (e.g., movies, television programs, academic lectures, etc.). In addition, the cache  206  can configure such that a user can override organization of the separator  404  to create new portions, modify size, etc. 
         [0067]    A recognizer  306  can be used to identify new content (e.g., transferred from a provider  304 ) and an organizer  406  can classify the identified multimedia content, such that the classification is based upon the cache portions. According to one embodiment, a collected song can include metadata describing a genre of the song. The organizer  406  can understand the genre through the metadata (e.g., the content is classified by a supplier). In one implementation, the content is placed in a cache portion associated with the genre—if a cache portion does not exist for that genre, then a new portion can be created for the genre. Alternatively, the content can be evaluated and a determination can be made on what existing cache portion the content best fits and/or if the content is close enough to an existing genre to merit placement (e.g., if placement is merited or a determination of portion is made, then storage of the content can occur; if there is not merit, then a new portion can be created and subsequent storage occurs). 
         [0068]    A grouper  408  can be used that matches the multimedia content with a classified cache that corresponds to the classification of the multimedia content—this can occur such that there is the automatic retention upon the matched classified cache. It is to be appreciated that content can be placed in more than one cache portion (e.g., in multiple physical locations, in multiple logical locations, etc.). The user can select to override operation of the grouper  408  and manually place content in an appropriate cache portion. A maintainer  308  can automatically retain at least a portion of the identified multimedia content automatically in a cache  206  (e.g., through use of the grouper  408 ). 
         [0069]    Referring to  FIG. 5 , an example system  500  for deleting content in a cache  206  of a content device  302  based upon usage of the content is showed. A recognizer  306  can identify multimedia content from a provider  304  and a maintainer  308  can retain at least a portion of the identified multimedia content automatically in a cache  206 . With the content placed in the cache  206 , a tag can be associated with the content—the tag can signify that the content should be observed for usage. 
         [0070]    An observer  502  can be employed that monitors usage of retained multimedia content. In one implementation, each time content is used (e.g., a song is played, a video is watched), a counter can be incremented; however, other implementations can be used, such as random times a check is made and an appropriate counter is incremented. A threshold level can be used, and when the counter is equal to or greater than the level, the content can be deleted. A manager  504  can be used that determines if the retained content should be deleted based at least upon a result of the monitoring—upon a positive determination, the content can be deleted. Limiting content by a number of times the content is played can assist in eliminating how often a piece of content is played. After deletion, there can be a time period determined and used before the content can again be retained in the cache  206 . According to one embodiment, the manager  504  does not function without consent of the user (e.g., globally, with each deletion, etc.) or the threshold level is provided by the user. 
         [0071]    Referring to  FIG. 6 , an example system  600  is disclosed for deleting content from a provider  306  or other source upon cache  206  based upon the content remaining on the cache  206  for too long of a period of time. A recognizer  306  can identify multimedia content perceived by a content device  304  that should be retained upon the cache  206 —the content commonly originates from a provider  306  (e.g., via a base station). A maintainer  308  can determine if the content should be retained and automatically retain the content based upon a positive determination. 
         [0072]    When retaining the content, a timestamp can be associated with the content to disclose when the content enters the cache  206 . A timer  602  can be used that determines an amount of retention time for retained multimedia content. The amount of retention time used to determine when to delete can be designated by a user, supplied through use of artificial intelligence techniques, etc. 
         [0073]    It is to be appreciated that artificial intelligence techniques can be used to practice determinations and inferences disclosed in the subject specification. These techniques employ one of numerous methodologies for learning from data and then drawing inferences and/or making determinations related to dynamically storing information across multiple storage units (e.g., Hidden Markov Models (HMMs) and related prototypical dependency models, more general probabilistic graphical models, such as Bayesian networks, e.g., created by structure search using a Bayesian model score or approximation, linear classifiers, such as support vector machines (SVMs), non-linear classifiers, such as methods referred to as “neural network” methodologies, fuzzy logic methodologies, and other approaches that perform data fusion, etc.) in accordance with implementing various automated aspects described herein. These techniques can also include methods for capture of logical relationships such as theorem provers or more heuristic rule-based expert systems. These techniques can be represented as an externally pluggable module, in some cases designed by a disparate (third) party. 
         [0074]    A measurer  604  can determine if the retained content should be deleted based at least upon the determined retention time such that content with a longest retention time is deleted. According to one embodiment, when content is retained for a period of time, the content can be deleted (e.g., automatically, with user approval, etc.). However, content automatic deletion can be limited such that content retained for a longest period is deleted when space is at a premium (e.g., to create storage space for new content). Multiple factors can be taken into account when determining if deletion should occur (e.g., period of time, number of times content is played, etc.). The measurer  604  can be limited in functionality such that operation is restricted for times when there is a need for more memory—a determination is made from the measurer  604  that there is a need for more space and the measurer  604  can determine what content should be deleted (e.g., based upon number of times used, time retained on the device, etc.). 
         [0075]    Referring to  FIG. 7 , an example system  700  is disclosed that regulates retention of information upon a cache  206  for a content device  302 —the information can originate from a provider  304 . A recognizer  306  can be used that identifies multimedia content. According to one embodiment, a user can download content for a music store and based upon a download request, identification can occur. 
         [0076]    Quality of content (e.g., audio quality for a song, quality derived from a wireless connection, etc.) can be of high importance. An analyzer  702  can be used that determines a quality level of the multimedia content. A selector  704  can determine if the multimedia content is of a sufficient quality level, automatic retention occurs upon determining that the identified multimedia content is of the suitable quality level. If a negative determination is made (e.g., the level is not of a high enough quality), then content can be disregarded. For example, obtained content can be compared against matching content (e.g., a same song) and a conclusion can be drawn on which song is of higher quality—a higher quality song is retained while a lower quality song is deleted. A maintainer  308  can retain at least a portion of the identified multimedia content automatically in a cache  206 . 
         [0077]    Deletion can occur based upon a quality level of content. For example, content can be retained in the cache  206  until the cache  206  is filled. Upon filling the cache  206 , content can be deleted based upon content quality (e.g., content with a lowest quality is deleted first). An evaluator  706  can be used that determines if the retained content should be deleted based at least upon the determined quality level of the retained multimedia content such that multimedia content of a lowest quality level is deleted. Other examples of removal from a full cache  206  are longest in time, designated by a user, first in-first out, expiration, etc. 
         [0078]    Referring to  FIG. 8 , an example system  800  is disclosed for regulating content retention regarding content expiration. A provider  304  can transfer multimedia content to a content device  302 . According to one embodiment, the provider  304  can sell or give the content to the content device  302 —however, there can be restrictions on the content such as the content cannot be saved elsewhere (e.g., a location other than the cache  206 ), the content is to be deleted after a number of plays, deleted after a set amount of time, etc. An identifier  302  and maintainer  304  can facilitate placement of the content upon the cache  206 . 
         [0079]    A verifier  802  can determine if retained multimedia content is expired (e.g., been retained too long, played too many times, there is a violation of a usage agreement, there is tampering with the cache  206 , etc.). A confirmer  804  can delete the retained multimedia content if it is determined that the content is expired. A notice can be transferred to the user notifying of the deletion. In an alternative embodiment, when expiration occurs, a notice can be given to a user that deletion occurs until the user takes an action (e.g., negotiates to have the expiration removed by paying more money, user requests deletion not occur, and the like). 
         [0080]    Referring to  FIG. 9 , an example system  900  is shown for playing content retained in the cache  206  (e.g., supplied for a provider  304 ). A content device  302  can include a recognizer  306  that identifies multimedia content (e.g., based on identification metadata associated with the content). An obtainer  902  can be used that collects a user instruction to retain the multimedia content (e.g., through the user interface  214  of FIG.  2 )—multimedia content associated with the user instruction is retained. A tester  904  can measure availability of cache portions to determine where to place the content. A maintainer  304  can retain at least a portion of the identified multimedia content automatically in a cache. Retention can occur upon a cache portion with a highest availability overall, highest availability in a related portion, and the like. A signal can be collect to play content and a reclaimer  906  can retrieve (e.g., remove from the cache, play from the cache, make a copy, etc.) at least a portion of the retained multimedia content. 
         [0081]    According to one embodiment, retrieval and/or deletion is governed by a scoring system. Different pieces of content can be assigned points based upon different characteristics and based upon a score, pieces can be retrieved, deleted, compressed, etc. The scoring system can be governed by a rules set that can be hard coded, modifiable by a central server, modifiable by a user, etc. For example, songs with a moderate audio quality can receive a penalty—the same can take place for songs that expired and songs previously played. The penalties can be aggregated together and retained (as well as updated when appropriate). 
         [0082]    Referring to  FIG. 10 , an example system  1000  is disclosed for managing content supplied by a provider  304 . The provider  304  can be a real-time source of content, such as a radio station, and supply content to a content device  302 . A recognizer  306  can identify content that can be placed in a cache  206 . With a proper identification, a maintainer  308  can retain the content. 
         [0083]    A regulator  1002  can be used that determines if usage of real-time multimedia content if suitable. Playing from the real-time source can occur upon determining that the usage is suitable. However, if it is not suitable (e.g., quality is too low, multiple stations are retrieved upon a single frequency, etc.), then content from the cache  206  can be played. In this scenario, a discloser  1002  plays at least a portion of the retained multimedia content. Targeted advertisements can be disclosed while playing content from the cache  206 . The advertisements can be based upon a section of a cache used (e.g., advertisement for a rock concert if the user is listening to rock, such as for a band of a song that finishes playing), a user location, etc. An augmenter  1006  can play the retained content with a tailored advertisement and the advertisement can tailored to the played content. 
         [0084]    Referring to  FIG. 11 , an example methodology  1100  is disclosed for retaining multimedia content, commonly upon a cache of a personal electronic device. Content for retention can be identified at event  1102 . Once identified, a check  1104  can be performed on if the content can be classified (e.g., does the content have a classification of a certain type such as music type, can the content be appreciated, etc.). If the classification can be classified or should be classified, then classification can occur through action  1106 . Based upon the classification, a match can occur to an appropriate storage location through event  1108 . According to one embodiment, a singular cache can be used and thus there can no classification check since items that are to be retained are stored in one location or the check  1104  determines classification should not occur. 
         [0085]    Regardless of the result of the check  1006 , there can be retaining of the identified content at action  1110 , commonly in the cache. Usage of the content can be observed through act  1112 —observation can include determining how often content is viewed, how often content is played upon a radio station perceived by a content device, and the like. Through this usage, it can be determined that the cache should be segmented. Analysis of the cache and contents can occur and based upon a result of the analysis the cache can be segmented at action  1114 . With the cache divided (e.g., into a movies section and other section), management of the cache can occur (e.g., placing movies in the movie section and other into the other section). 
         [0086]    Referring to  FIG. 12 , an example methodology  1200  is disclosed for having storage of content (e.g., a cache) integrate with a real-time content source. Content that enters a content device can be identified as such in action  1202 . A check  1204  can be performed to determine if the content should be retained. If it is determined there should be no retention (e.g., no retention at that time, no retention ever), then the content can be played at act  1206 . It is to be appreciated that content can be played while retained as well. 
         [0087]    If it is determined that the content should be saved, then retention can occur at action  1208 . An observation of content usage can take place at event  1210  and based upon the observation a check  1212  can determine if the content should be deleted. Deletion can occur based upon how long content is retained, usage restrictions, available space, quality of content, number of times played, and the like. If the check  1212  determines that the content should not be deleted, then observation can continue to occur and the check  1212  can continue to run until deletion is appropriate. It is to be appreciated that other instances (e.g., playing content) can occur while the observation and check occur. If it is determined that content should be deleted, the removal of the content can occur at act  1214   
         [0088]    At event  1216 , a user instruction can be collected to play the content (e.g., upon determining the content should not be deleted). Analysis of the user and/or the content can occur and the content can be augmented with a specific advertisement at act  1218 , the advertisement is selected based upon a result of the analysis. The content can be disclosed at event  1220  (e.g., with a general advertisement, with a tailored advertisement, without an advertisement, etc.). 
         [0089]    Referring to  FIG. 13 , an example methodology  1300  is disclosed for operation of a multimedia content provider. At action  1302 , there can be analyzing communication channels and identifying a broadcast load based upon a result of the analysis. Through event  1304  there can be determining an amount of multimedia content to provide based upon the identified load. Determining content to provide can take place at act  1306 —the determination can be based upon a user request, a station instruction, designation from a third-party, etc. With action  1308 , disclosure of the content can occur; verification can take place to determine if the content arrives and if the content does not arrive, then disclosure can be repeated. Additionally, there can be monitoring the content once delivered to determine if there is a usage violation. If a violation occurs, then a notice can be sent, the content can be removed, further disclosure to a device or user can be halted, etc. 
         [0090]    Referring to  FIG. 14 , an example methodology  1400  is disclosed for obtaining content from a music store. At event  1402 , a user can subscribe to a music store in order to obtain content. Content can be designated by the user, suggested by the store, inferred from holdings in a personal cache, etc. and be purchased at action  1404 . At event  1406 , a user can engage content and the music store can evaluate the usage. Based upon a result of the evaluation, new music can be automatically provided to the user (e.g., for a fee, free of charge, for completion of a survey, etc.). The user can learn of new music at action  1408  (e.g., through a tailored advertisement, listening to a radio station, . . . ) and new music can be purchased and downloaded through act  1410 —thus, the music can be identified and retained. 
         [0091]    Referring to  FIG. 15 , an example methodology  1500  is disclosed for obtaining content from a real-time source, such as a radio station. A user can subscribe to a radio service (e.g., satellite radio) through event  1502 . A set of user preferences can be collected through event  1504  and based upon the preferences, a music channel can be selected at act  1506  (e.g., automatically implemented, suggested, etc.). It is to be appreciated that the user can override the preference selection and select a radio station. As part of the subscription service, a user can download music played upon a radio station. Content can be transferred at event  1508  and a user can designate a song to download at action  1510 . According to an alternative embodiment, the content can be automatically selected for downloading. The music can be identified and retained at act  1512 . 
         [0092]    Referring to  FIGS. 11-15 , methodologies relating to a usage of multimedia content. While, for purposes of simplicity of explanation, the methodologies are shown and described as a series of acts, it is to be understood and appreciated that the methodologies are not limited by the order of acts, as some acts can, in accordance with one or more embodiments, occur in different orders and/or concurrently with other acts from that shown and described herein. For example, those skilled in the art will understand and appreciate that a methodology could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all illustrated acts can be required to implement a methodology in accordance with one or more embodiments. 
         [0093]    It will be appreciated that, in accordance with one or more aspects described herein, inferences can be made regarding whether a there should be deletion of content of a cache, if content should be retained, etc. As used herein, the term to “infer” or “inference” refers generally to the process of reasoning about or inferring states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic-that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources. It will be appreciated that the foregoing examples are illustrative in nature and are not intended to limit the number of inferences that can be made or the manner in which such inferences are made in conjunction with the various embodiments and/or methods described herein. 
         [0094]      FIG. 16  is an illustration of a mobile device  1600  (e.g., the mobile device  1600  can be an example content device  302 ) that facilitates management of information upon a cache. Mobile device  1600  comprises a receiver  1602  that receives a signal from, for instance, a receive antenna (not shown), and performs typical actions thereon (e.g., filters, amplifies, downconverts, etc.) the received signal and digitizes the conditioned signal to obtain samples. Receiver  1602  can be, for example, an MMSE receiver, and can comprise a demodulator  1604  that can demodulate received symbols and provide them to a processor  1606  for channel estimation. Processor  1606  can be a processor dedicated to analyzing information received by receiver  1602  and/or generating information for transmission by a transmitter  1616 , a processor that controls one or more components of mobile device  1600 , and/or a processor that both analyzes information received by receiver  1602 , generates information for transmission by transmitter  1616 , and controls one or more components of mobile device  1600 . 
         [0095]    Mobile device  1600  can additionally comprise memory  1608  that is operatively coupled to processor  1606  and that can store data to be transmitted, received data, information related to available channels, data associated with analyzed signal and/or interference strength, information related to an assigned channel, power, rate, or the like, and any other suitable information for estimating a channel and communicating via the channel. Memory  1608  can additionally store protocols and/or algorithms associated with estimating and/or utilizing a channel (e.g., performance based, capacity based, etc.). 
         [0096]    It will be appreciated that the data store (e.g., memory  1608 ) described herein can be either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. By way of illustration, and not limitation, nonvolatile memory can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable PROM (EEPROM), or flash memory. Volatile memory can include random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation, RAM is available in many forms such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct Rambus RAM (DRRAM). The memory  1608  of the subject systems and methods is intended to comprise, without being limited to, these and any other suitable types of memory. 
         [0097]    Processor  1602  is further operatively coupled to a recognizer  1610  that identifies multimedia content and a maintainer  1612  that retains at least a portion of the identified multimedia content automatically in a cache. Mobile device  1600  still further comprises a modulator  1614  and a transmitter  1616  that transmits a signal (e.g., base CQI and differential CQI) to, for instance, a base station, another mobile device, etc. Although depicted as being separate from the processor  1606 , it is to be appreciated that the recognizer  1610  and/or maintainer  1612  can be part of processor  1606  or a number of processors (not shown). 
         [0098]      FIG. 17  is an illustration of a system  1700  that facilitates management of multimedia content. System  1700  comprises a base station  1702  (e.g. access point, provider  304  of  FIG. 3 , . . . ) with a receiver  1710  that receives signal(s) from one or more mobile devices  1704  through a plurality of receive antennas  1706 , and a transmitter  1724  that transmits to the one or more mobile devices  1704  through a plurality of transmit antennas  1708 . Receiver  1710  can receive information from receive antennas  1706  and is operatively associated with a demodulator  1712  that demodulates received information. Demodulated symbols are analyzed by a processor  1714  that can be similar to the processor described above with regard to  FIG. 16 , and which is coupled to a memory  1716  that stores information related to estimating a signal (e.g., pilot) strength and/or interference strength, data to be transmitted to or received from mobile device(s)  1704  (or a disparate base station (not shown)), and/or any other suitable information related to performing the various actions and functions set forth herein. 
         [0099]    Processor  1714  is further coupled to a classifier  1718  that identifies a broadcast load as well as a resolver  1720  that determines an amount of multimedia content to provide based upon the identified load. Information to be transmitted can be provided to a modulator  1722 . Modulator  1722  can multiplex the information for transmission by a transmitter  1724  through antenna  1708  to mobile device(s)  1704 . Although depicted as being separate from the processor  1714 , it is to be appreciated that the classifier  1718  and/or resolver  1720  can be part of processor  1714  or a number of processors (not shown). 
         [0100]      FIG. 18  shows an example wireless communication system  1800 . The wireless communication system  1800  depicts one base station  1810  and one mobile device  1850  for sake of brevity. However, it is to be appreciated that system  1800  can include more than one base station and/or more than one mobile device, wherein additional base stations and/or mobile devices can be substantially similar or different from example base station  1810  and mobile device  1850  described below. In addition, it is to be appreciated that base station  1810  and/or mobile device  1850  can employ the systems ( FIGS. 1-10  and  16 - 17 ) and/or methods ( FIGS. 11-15 ) described herein to facilitate wireless communication there between. 
         [0101]    At base station  1810 , traffic data for a number of data streams is provided from a data source  1812  to a transmit (TX) data processor  1814 . According to an example, each data stream can be transmitted over a respective antenna. TX data processor  1814  formats, codes, and interleaves the traffic data stream based on a particular coding scheme selected for that data stream to provide coded data. 
         [0102]    The coded data for each data stream can be multiplexed with pilot data using orthogonal frequency division multiplexing (OFDM) techniques. Additionally or alternatively, the pilot symbols can be frequency division multiplexed (FDM), time division multiplexed (TDM), or code division multiplexed (CDM). The pilot data is typically a known data pattern that is processed in a known manner and can be used at mobile device  1850  to estimate channel response. The multiplexed pilot and coded data for each data stream can be modulated (e.g., symbol mapped) based on a particular modulation scheme (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM), etc.) selected for that data stream to provide modulation symbols. The data rate, coding, and modulation for each data stream can be determined by instructions performed or provided by processor  1830 . 
         [0103]    The modulation symbols for the data streams can be provided to a TX MIMO processor  1820 , which can further process the modulation symbols (e.g., for OFDM). TX MIMO processor  1820  then provides N T  modulation symbol streams to N T  transmitters (TMTR)  1822   a  through  1822   t.  In various embodiments, TX MIMO processor  1820  applies beamforming weights to the symbols of the data streams and to the antenna from which the symbol is being transmitted. 
         [0104]    Each transmitter  1822  receives and processes a respective symbol stream to provide one or more analog signals, and further conditions (e.g. amplifies, filters, and upconverts) the analog signals to provide a modulated signal suitable for transmission over the MIMO channel. Further, N T  modulated signals from transmitters  1822   a  through  1822   t  are transmitted from N T  antennas  1824   a  through  1824   t,  respectively. 
         [0105]    At mobile device  1850 , the transmitted modulated signals are received by N R  antennas  1852   a  through  1852   r  and the received signal from each antenna  1852  is provided to a respective receiver (RCVR)  1854   a  through  1854   r.  Each receiver  1854  conditions (e.g., filters, amplifies, and downconverts) a respective signal, digitizes the conditioned signal to provide samples, and further processes the samples to provide a corresponding “received” symbol stream. 
         [0106]    An RX data processor  1860  can receive and process the N R  received symbol streams from N R  receivers  1854  based on a particular receiver processing technique to provide N T  “detected” symbol streams. RX data processor  1860  can demodulate, deinterleave, and decode each detected symbol stream to recover the traffic data for the data stream. The processing by RX data processor  1860  is complementary to that performed by TX MIMO processor  1820  and TX data processor  1814  at base station  1810 . 
         [0107]    A processor  1870  can periodically determine which preceding matrix to utilize as discussed above. Further, processor  1870  can formulate a reverse link message comprising a matrix index portion and a rank value portion. 
         [0108]    The reverse link message can comprise various types of information regarding the communication link and/or the received data stream. The reverse link message can be processed by a TX data processor  1838 , which also receives traffic data for a number of data streams from a data source  1836 , modulated by a modulator  1880 , conditioned by transmitters  1854   a  through  1854   r,  and transmitted back to base station  1810 . 
         [0109]    At base station  1810 , the modulated signals from mobile device  1850  are received by antennas  1824 , conditioned by receivers  1822 , demodulated by a demodulator  1840 , and processed by a RX data processor  1842  to extract the reverse link message transmitted by mobile device  1850 . Further, processor  1830  can process the extracted message to determine which preceding matrix to use for determining the beamforming weights. 
         [0110]    Processors  1830  and  1870  can direct (e.g., control, coordinate, manage, etc.) operation at base station  1810  and mobile device  1850 , respectively. Respective processors  1830  and  1870  can be associated with memory  1832  and  1872  that store program codes and data. Processors  1830  and  1870  can also perform computations to derive frequency and impulse response estimates for the uplink and downlink, respectively.
